Glossary

“assay” means to test minerals by chemical or other methods for determining the amount of metals contained therein.

“claim” means a mining interest giving its holder the right to prospect, explore for and exploit minerals within a defined area.

“feasibility study” means a comprehensive study undertaken to determine the economic feasibility of a project; typically to determine if a construction and/or production decision can be made.

“grade” means the amount of precious metal in each ton of mineralized material, expressed as troy ounces per ton.

“heap leaching” means a process whereby gold and silver are extracted by “heaping” crushed mineralized material onto impermeable leach pads and applying a weak cyanide solution that dissolves the gold and silver from the material into a precious metal-laden solution for further recovery.

“lode” is a vein-like deposit or rich supply of or source of gold or other minerals.

“mineral deposit” is a body that contains mineralization that has been delineated by appropriately spaced drilling and/ or underground sampling to estimate a sufficient tonnage and average grade of metal(s). Such a deposit does not qualify as a reserve until a comprehensive evaluation based upon unit cost, grade, recoveries, and other material factors conclude legal and economic feasibility of extraction at the time of reserve determination.

“NSR” means net smelter return.

“ore” means mineral-bearing material, which is economically (valuable enough to be mined at a profit) and legally extractable.

“placer” means alluvial deposit containing particles or larger pieces of gold or other minerals.

“probable reserves” means reserves for which quantity and grade and/or quality are computed from information similar to that used for proven (measured) reserves, but the sites for inspection, sampling and measurement are farther apart or are otherwise less adequately spaced. The degree of assurance, although lower than that for proven (measured) reserves, is high enough to assume continuity between points of observation.

“proven reserves” means reserves for which (a) quantity is computed from dimensions revealed in outcrops, trenches, workings or drill holes; grade and/or quality are computed from the results of detailed sampling and (b) the sites for inspection, sampling and measurement are spaced so closely and the geologic character is so well defined that size, shape, depth, and mineral content of reserves are well-established.

“quartz” is one of the most common of all rock-forming minerals and one of the most important constituents of the earth’s crust. Quartz may be transparent, translucent, or opaque; it may be colorless or colored.

“recovery” means that portion of the metal contained in the mineralized material that is successfully extracted by processing, usually expressed as a percentage.

“reserve” or “mineral reserve” is the economically and legally mineable part of a Measured and/or Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at Pre-Feasibilty or Feasibility level as appropriate that include application of modifying factors. Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified ( CIM Definition Standards , 2014).

“resource” or “mineral resource” is a concentration or occurrence of solid material of economic interest in or on the Earth’s crust in such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity, grade or quality, continuity and other geological characteristics of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge, including sampling ( CIM Definition Standards , 2014).

“stripping ratio” or “strip ratio” means the ratio of waste tons to ore tons mined.

“tailings” means refuse materials resulting from the washing, concentration, or treatment of mineralized material.

“ton” means a short ton (2,000 pounds).

“vein” is a deposit of non-sedimentary origin, which may or may not contain valuable minerals; lode.

“waste” means rock or other material lacking sufficient grade and/or other characteristics to be economically processed or stockpiled and which must be mined to access the valuable portion of a mineral deposit.

PART I

Item 1. Business

OUR COMPANY

Unless the context otherwise indicates, the terms “Comstock,” “we,” “us,” “our,” “our Company” or “the Company” mean Comstock Mining Inc. and its consolidated subsidiaries.

The Company is a Nevada-based, gold and silver mining exploration, development and production company with extensive, contiguous property in the historic Comstock and Silver City mining districts (collectively, the “Comstock District”) and additional mining, commercial and industrial properties located in Storey and Lyon Counties, Nevada. The Comstock District is located within the western portion of the Basin and Range Province of Nevada, near Reno and Carson City. The Company began acquiring properties and developing projects in the Comstock District in 2003. Since then, the Company has consolidated a substantial portion of the historic Comstock District, secured permits, built an infrastructure and brought exploration projects into production.

The Company and its subsidiaries now own or control approximately 9,272 acres of mining claims and parcels in the Comstock District and surrounding area. The acreage is comprised of approximately 2,347 acres of patented claims and surface parcels (private lands) and approximately 6,925 acres of unpatented mining claims (public lands), which the Bureau of Land Management (“BLM”) administers. The Company's headquarters is in Gold Hill, Nevada, on a five-acre parcel at the intersection of American Flat road and State Route 342.

Because of the Comstock District’s historical significance, the geology is well known and has been extensively studied by the Company, our advisors and many independent researchers. We have expanded our understanding of the geology of the project area through vigorous surface mapping and drill hole logging. The volume of geologic data is immense, particularly in the Lucerne and Dayton resource areas. We have amassed a large library of historical data and detailed surface mapping of Comstock District properties and continue to obtain historic information from private and public sources. We use such data in conjunction with information obtained from our recent mining operations, to target geological prospective exploration areas and plan exploratory drilling programs, including expanded surface and underground drilling.

The Company continues evaluating and acquiring properties, expanding its footprint and exploring all of our existing and prospective opportunities for further exploration, development and mining. The near-term goal of our business plan is to maximize intrinsic stockholder value realized, per share, by continuing to acquire and develop mineralized and potentially mineralized properties, exploring, developing and validating qualified resources (measured, indicated and inferred) and reserves (proven and probable) that enable the commercial development of our operations through extended, long-lived mine plans that are economically feasible and socially responsible, including mine plans for both the Lucerne and Dayton resource areas, with both surface and underground development opportunities.

Our Lucerne resource area is located in Storey County, Nevada, approximately three miles south of Virginia City and 30 miles southeast of Reno. The Lucerne resource area was host to the Company’s most-recent test mining operations from 2012 through 2016. The heap processing facility for gold and silver is in American Flat, approximately three quarters of a mile west of the Lucerne mine. The heap leach facility was redesigned and expanded in late 2013 and again in the fourth quarter of 2014, to accommodate future production plans.

The Company achieved initial production and held its first pour of gold and silver on September 29, 2012. The Company ceased mining in 2015 and completed processing in 2016, and accordingly did not have any gold or silver production or mining revenue during 2017. From 2012 through 2016, the Company mined and processed approximately 2.6 million tons of mineralized material, and produced 59,515 ounces of gold and 735,252 ounces of silver.

Our Dayton resource area is located in Lyon County, Nevada, approximately six miles south of Virginia City. Access to the properties is by State Routes 341/342, a paved road.

The Company's exploration and development activities to date have focused on less than 10% of our extensive Comstock District properties. We continue to develop longer-term exploration plans for additional exploration targets. In addition to targets in our Lucerne and Dayton resource areas, some of the more promising exploration targets include the Spring Valley group, Occidental group and Gold Hill group.

The Company’s real estate segment owns significant non-mining properties, including the Gold Hill Hotel, rentable homes and cottages in Gold Hill and Silver City, Nevada, the 225-acre Daney Ranch in Dayton, Nevada and a 98-acre

Industrial Park in Silver Springs, Nevada, including senior water rights. The Gold Hill Hotel includes an operating historic hotel, restaurant and a bar. In 2015, the Company entered into an agreement to lease the Gold Hill Hotel to independent operators while retaining ownership. The initial term of the lease agreement was effective on April 1, 2015, and ends in March 2020. The tenant may renew the lease for two extended terms of five years each. Lease payments are due in monthly installments.

Financial information for each of our segments is disclosed in Note 12 to the consolidated financial statements.

Figure 1 - Comstock Mining's Land Position in the Comstock District

Current Projects

The Company has identified many exploration targets on its land holdings in the Comstock District, but has focused, to date, on the Lucerne resource area (including surface and underground exploration) and the Dayton resource area. We are working to develop comprehensive exploration plans for the remaining areas, which include the Spring Valley group, Occidental group, and Gold Hill group of exploration targets. Exploration activities will proceed subsequent to and in some cases concurrent with the ongoing exploration and development of the Lucerne and Dayton resource areas.

The Lucerne resource area has been the primary focus of the Company’s exploration and development efforts since 2007. It includes the previously mined Billie the Kid, Hartford and Lucerne mining patents, and extends east and northeasterly to the area of the historic Woodville (southern-most of the historic Comstock bonanzas), Succor and Lager Beer patents and north to the historic Justice and Keystone mines. The Lucerne resource area is approximately one mile along strike, with explored widths from 600 to 1,800 feet, representing less than three percent of the land holdings controlled by the Company. The Lucerne is the site of our previous mining activities and ongoing exploration program, and the Company holds the key mining permits required to resume surface or underground mining this area.

Our Lucerne exploration activities included open pit gold and silver test mining from 2004, through 2006, and from late 2012 through 2016. As defined by the Securities Exchange Commission (“SEC”) Industry Guide 7, we have not yet established any proven or probable reserves at our Lucerne mine.

On October 3, 2017, the Company entered into an Option Agreement (the “Option Agreement”) with Tonogold Resources, Inc. (“Tonogold”). Under the terms of the Option Agreement, Tonogold has certain rights to participate in certain activities, including engineering, development, drilling and test-work, towards completing a technical and economic feasibility assessment on certain properties within the Lucerne resource area (the “Lucerne Property”). If all obligations and prerequisites are satisfied and subject to compliance with the Option Agreement, Comstock and Tonogold may effect a joint venture for the future development and mining of mineral resources in the Lucerne Property.

Under the terms of the Option Agreement, Tonogold can earn a 51% interest in the Company’s wholly-owned subsidiary, Comstock Mining LLC, which owns the Lucerne Property, by making $20 million in capital expenditures on the Lucerne Property within 42 months following signing of the Option Agreement. If Tonogold meets all of the prerequisites, Tonogold is also granted the option to purchase 51% of certain equipment and property located at the Company’s American Flat property for an additional purchase price of $25 million.

The Dayton resource area is south of Virginia City in Lyon County, Nevada. It generally includes the historic Dayton, Kossuth and Alhambra patents, including the old Dayton Consolidated mine workings, south to where the Kossuth patent crosses State Route 341. The historic Dayton mine was the last meaningful underground mining operation in the Comstock District, before being closed after the War Production Board promulgated Limitation Order L-208, 7 F. R. 7992 on October 8, 1942, that closed down all gold mining operations in the United States and its territories. The Dayton resource area ranks as one of the Company’s top exploration and potential mine development targets. In January 2014, the Lyon County Board of Commissioners approved strategic master plan and zoning changes on the Dayton, Kossuth and Alhambra mining patents and other properties located in the Dayton resource area, enabling a more practical, comprehensive feasibility study for mining. Geological studies and development planning are currently underway utilizing data from extensive metallurgical testing and assessment during 2017, 30,818 feet of drilling completed in 2015, geophysical analysis and interpretation completed in 2013 and extensive geological data from pre-2013, drill programs.

The Spring Valley group of exploration targets lies at the southern end of the Comstock District, where the mineralized structures, trending to the south from the Dayton resource area, lie mostly concealed beneath a veneer of sediment gravels. The area includes the Kossuth patented claim south of State Route 341, the Dondero patented property, the Daney patented claim, the New Daney lode mining claims, and the Company’s placer mining claims in Spring Valley and Gold Canyon.

The Occidental group and Gold Hill group of exploration targets represent longer-term exploration target areas that contain many historic mining operations, including the Overman, Con Imperial, Caledonia, and Yellow Jacket mines. We believe that our consolidation of the Comstock District has provided us with opportunities to utilize the historical information available to identify drilling targets with significant potential.

Our Comstock exploration activities included open pit gold and silver test mining from late 2012 through 2016. As defined by the Securities Exchange Commission (“SEC”) Industry Guide 7, we have not yet established any proven or probable reserves at our Comstock Lode Project.

Employees

As of December 31, 2017 , we have 12 full-time employees, inclusive of our general and administrative function.

Principal Markets

We sell our gold and silver production on world markets at prices established by commodity markets. These prices are not within our control. We did not have any production or revenue in our mining segment during 2017, and we had $0.1 million of revenues in our real estate segment for the year ended December 31, 2017 . We had an operating loss of $8.9 million in our mining segment and an operating profit of $ 30,590 in our real estate segment, respectively, during the year ended December 31, 2017 . We had total assets of $25.5 million and $ 5.4 million in our mining and real estate segments, respectively, as of December 31, 2017 . See Note 12 to our audited consolidated financial statements for additional information regarding our segments.

Government Regulation

Mining operations and exploration activities are subject to various national, state, and local laws and regulations in the United States, which govern prospecting, development, mining, production, exports, taxes, labor standards, occupational health, waste disposal, protection of the environment, mine safety, hazardous substances, and other matters. We have obtained or have pending applications for substantially all of those licenses, permits, and other authorizations currently required for our mining, exploration and other development programs. We believe that we are in compliance in all material respects with applicable mining, health, safety and environmental statutes and regulations. Capital expenditures relating to compliance with laws and regulations that regulate the discharge of materials into the environment, or otherwise relating to the protection of the environment, comprise a substantial part of our historical capital expenditures and our anticipated future capital expenditures. For example, we incur certain expenses and liabilities associated with our reclamation obligations. See “Reclamation” section below.

Reclamation

We are generally required to mitigate long-term environmental impacts by stabilizing, contouring, re-sloping, and re-vegetating various portions of a site after mining and mineral processing operations are completed. These reclamation efforts are conducted in accordance with plans reviewed and approved by the appropriate regulatory agencies.

The Nevada Revised Statutes (NRS) 519A to 519A.280 and Nevada Administrative Code (NAC) 519A.010 to 519A.415 promulgated by the Nevada State Environmental Commission and the Nevada Division of Environmental Protection (“NDEP”), Bureau of Mining and Reclamation (“BMRR”) require a surety bond to be posted for mining projects so that after completion of the work on such mining projects, the sites are left safe, stable and capable of providing for a productive post-mining use. Over the past four years, the Company has provided a reclamation surety bond, through the Lexon Surety Group (“Lexon”), with the BMRR. The BMRR, with concurrence from Storey County, has approved our most recent reclamation plan, as revised, and our estimated total costs related thereto of approximately $7.4 million , including, $7.1 million for BMRR and $0.6 million of additional reclamation surety bonding primarily with Storey County. For the years ended December 31, 2016 , and 2015 , the Company had provided estimates and surety bonds in the amounts of $11.6 million and $8.6 million, respectively.

As part of the surety agreement, the Company agreed to pay a 2.0% annual bonding fee and has signed a corporate guarantee. The cash collateral percentage held on deposit by Lexon is typically 32.7% or less of the current bond amount. The current bond amount with the State and County is $7.4 million and at December 31, 2017 , $2.5 million of collateral was held on deposit.

Competition

We compete with other mineral exploration and mining companies in connection with the acquisition of gold and other mineral properties and the attraction and retention of human capital. Such competitors may have substantially greater financial resources than we do.

History

The Company began acquiring properties and developing projects in the Comstock District in 2003. The Company produced over 12,000 ounces of gold and over 53,000 ounces of silver from 2004 through 2006 from our Billie the Kid mine and American Flat heap leach processing facilities. Our test mining activities were concluded in January 2007, when based on our longer-term production plans, we prioritized land consolidation and mine planning.

After five years of intensive geological mapping and interpretation, drilling, resource modeling and mine planning, the Company restarted mining operations in the third quarter of 2012 and resumed pouring doré bars of silver and gold in September 2012. The Company produced 59,515 ounces of gold and 735,252 ounces of silver from September 2012 through December 2016. The Company completed leaching from its existing leach pads in December 2016, and has since focused on exploration and development activities, primarily in the Lucerne and Dayton resource areas.

Customers

Substantially all mining revenues recorded to date relate to the same customer. As gold can be sold through numerous gold market traders worldwide, the Company is not economically dependent on a limited number of customers for the sale of its product. The real estate segment has numerous customers and is not dependent on any one customer.

Financing Events

In April 2017, the Company entered into an equity purchase agreement (the “Purchase Agreement”) with Leviston Resources LLC (“Leviston”) for the purchase of up to $7.25 million in shares of the Company's common stock and filed a prospectus supplement to its existing shelf registration statement for the purchase of up to $3.25 million in shares of the Company’s common stock from time to time, at the Company’s option, limited to $0.75 million per month, subject to certain volume and pricing restrictions. On December 28, 2017, the Company filed a second prospectus supplement to its existing shelf registration statement for the purchase of up to $4 million in shares of the Company's common stock, from time to time, with similar terms under the Purchase Agreement. During 2017, the Company received net proceeds of $3.15 million from the sale of shares under the Purchase Agreement and has $4.1 million available as of December 31, 2017.

Effective June 28, 2016, the Company entered into a sales agreement with IAA with respect to an at-the-market offering program (“ATM Agreement”) pursuant to which the Company may offer and sell, from time to time at its sole discretion, shares of its common stock, having an aggregate offering price of up to $5.0 million. During 2017, and 2016, the Company received net proceeds of $4.1 million, and $0.5 million, respectively, under the ATM Agreement, and has $0.3 million available as of December 31, 2017.

Item 1A. Risk Factors

An investment in our securities involves risk. You should carefully consider the following risk factors, in addition to those discussed elsewhere in this report, in evaluating our Company, its business, its industry and prospects. The risks described below are not the only ones facing us. Additional risks not presently known to us, or that we currently deem immaterial, may also have a material adverse effect on us. The following risks could cause our business, financial condition, results of operations or cash flows to be materially and adversely affected. In that case, the market price of our securities could decline, and you could lose part or all of your investment.

You may lose all or part of your investment.

If we are unable to find, effectively develop, mine, recover and sell adequate quantities of gold and silver, it is unlikely that the cash generated from our internal operations will suffice as a source of the liquidity necessary for anticipated working capital requirements. There is no assurance that the Company’s initiatives to improve its liquidity and financial position will be successful. Accordingly, there is substantial risk that the Company will be unable to continue as a going concern. In the event of insolvency, liquidation, reorganization, dissolution or other winding up of the Company, the Company’s creditors would be entitled to payment in full out of the Company’s assets before holders of common stock would be entitled to any payment, and the claims on such assets may exceed the value of such assets.

We have a limited operating history.

We have a limited operating history. The success of our Company is significantly dependent on the uncertain events of the discovery and exploitation of mineralized materials on our properties or selling the rights to exploit those materials. If our business plan is not successful and we are not able to operate profitably, then our securities may become worthless and investors may lose all of their investment in our Company.

Because we may never earn significant revenues from our mine operations, our business may fail.

We recognize that if we are unable to generate significant revenues from the exploration and exploitation of our mineralized materials in the future, we will not be able to earn profits or continue operations. We have yet to generate positive earnings and there can be no assurance that we will ever operate profitably. There is no history upon which to base any assumption as to the likelihood that we will prove successful, and we can provide no assurance that we will generate significant revenues or ever achieve profitability. If we are unsuccessful, our business will fail and investors may lose all of their investment in our Company.

Transportation difficulties and weather interruptions may affect and delay proposed mining operations and impact our business plans .

Our mining properties are accessible by road. The climate in the area is hot and dry in the summer but cold and subject to snow and other precipitation in the winter, which could at times hamper accessibility depending on the winter season precipitation levels. As a result, our exploration and mining plans could be delayed for several months each year. Such delays could affect our anticipated business operations and increase our expenses.

Moreover, extreme weather events (such as increased frequency or intensity of hurricanes or prolonged drought, flooded or frozen terrain) have the potential to disrupt operations at our projects. Extended disruptions to supply lines due to extreme weather could result in interruption of activities at the project sites, delay or increase the cost of construction of the projects, or otherwise adversely affect our business.

Supplies and equipment needed for exploration may not always be available. If we are unable to secure exploration supplies we may have to delay our anticipated business operations .

Competition and unforeseen limited sources of supplies needed for our proposed exploration work could result in occasional shortages of supplies of certain products, equipment or materials. There is no guarantee we will be able to obtain certain products, equipment and/or materials as and when needed, without interruption, or on favorable terms, if at all. Such delays could affect our anticipated business operations and increase our expenses.

We have invested capital in high-risk mineral projects where we have not conducted sufficient exploration and engineering studies .

We have invested capital and have otherwise been involved in various mineral properties and projects in the Comstock District where we have not conducted sufficient exploration and engineering studies to minimize the risk of project failure. Our mineral projects involve high risks because we have not invested sufficiently in the characterization of mineralized material, geologic analysis, metallurgical testing, mine planning and economic analysis. Standard industry practice calls for a mining company to prepare a formal mine plan and mining production schedule and have these documents reviewed and validated by a third party specialist. We have not had a formal mine plan and mining production schedule economically validated by a third party specialist.

We will not be successful unless we recover precious metals and sell them for a profit.

Our success depends on our ability to recover precious metals, process them, and successfully sell them for more than the cost of production. The success of this process depends on the market prices of metals in relation to our costs of production. We may not be able to generate a profit on the sale of gold or other minerals because we have limited control over our costs and have no ability to control the market prices. The total cash costs of production at any location are frequently subject to great variation from year to year as a result of a number of factors, such as the changing composition of the grade of the mineralized material mined for production, and metallurgy and exploration activities in response to the physical shape and location of the mineral deposit. In addition, costs are affected by the price of commodities, such as fuel and electricity. Such commodities are at times subject to volatile price movements, including increases that could make production unprofitable. A material increase in production costs or a decrease in the price of gold or other minerals could adversely affect our ability to earn a profit on the sale of gold or other minerals.

We do not have proven or probable reserves, and there is no assurance that the quantities of precious metals we produce will be sufficient to recover our investment and operating costs.

We do not have proven or probable reserves. Substantial expenditures are required to acquire existing gold properties with established reserves or to establish proven or probable reserves through drilling, analysis and engineering. Any sums expended for additional drilling, analysis and engineering may not establish proven or probable reserves on our properties. We drill in connection with our mineral exploration and mining activities and not with the purpose of establishing proven and probable reserves. While we estimate the amount of mineralized material we believe exists on our properties, our calculations are subject to uncertainty due to several factors, including the quantity and grade of the mineralized material, metal prices and recoverability of minerals in the mineral recovery process. There is a great degree of uncertainty attributable to the calculation of any mineralized material, particularly where there has not been significant drilling, mining and processing. Until the mineralized material located on our properties is actually mined and processed, the quantity and quality of the mineralized material must be considered as an estimate only. In addition, the estimated value of such mineralized material (regardless of the quantity) will vary depending on metal prices. Any material change in the estimated value of mineralized material may negatively affect the economic viability of our properties. In addition, there can be no assurance that we will achieve the same recoveries of metals contained in the mineralized material as in small-scale laboratory tests or that we will be able to duplicate such results in larger scale tests under on-site conditions or during production. There can be no assurance that our exploration activities will result in the discovery of sufficient quantities of mineralized material to recover our investment and operating costs.

The cost of our exploration and acquisition activities is substantial, and there is no assurance that the quantities of minerals we discover or acquire will justify commercial operations or replace reserves (to the extent reserves are established in the future).

Mineral exploration, particularly for gold and other precious metals, is highly speculative in nature and frequently is nonproductive. There can be no assurance that our exploration and acquisition activities will be commercially successful. If gold mineralization is discovered, it may take a number of years from the initial phases of drilling until production is possible, during which time the economic feasibility of production may change. Substantial expenditures are required to acquire existing gold properties, to establish mineral reserves through drilling and analysis, to develop metallurgical processes to extract metal from the mineralized material, and in the case of new properties, to develop the processing facilities and infrastructure at any site chosen for mineral exploration. There can be no assurance that any gold reserves or mineralized material that may be discovered or acquired in the future, if any, will be in sufficient quantities or of adequate grade to justify commercial operations or that the funds required for mineral production operation can be obtained on a timely or reasonable basis, if at all. Mining companies must continually replace mineralized material or reserves depleted by production. There can be no assurance that we will be successful in replacing any reserves or mineralized material acquired or established in the future.

The price of gold and silver fluctuate on a regular basis and a downturn in price could negatively impact our operations and cash flow.

Our operations will be significantly affected by changes in the market price of gold and silver if we are able to produce gold or other minerals. Gold and silver prices can fluctuate widely and may be affected by numerous factors, such as expectations for inflation, levels of interest rates, currency exchange rates, purchases and sales by governments and central banks, monetary policies employed by the world’s major central banks, fiscal policies employed by the world’s major industrialized economies, forward selling or other hedging activities, demand for precious metals, global or regional political and economic crises and production costs in major gold-producing regions, such as but not limited to South Africa and the former Soviet Union. The aggregate effect of these factors, all of which are beyond our control, is impossible for us to predict. If gold or silver prices decline substantially, it could adversely affect the realizable value of our assets and potentially, future results of operations and cash flow.

We plan to pursue opportunities to acquire properties with gold or silver reserves or mineralized material with exploration potential. The price that we pay to acquire these properties will be influenced, in large part, by the price of gold and silver at the time of the acquisition. We expect our potential future revenues to be derived from the production and sale of gold and silver from these properties or from the sale of some of these properties. The value of any mineralized material, and the value of any potential mineral production therefrom, will vary in direct proportion to variations in those mineral prices. The price of gold and silver has fluctuated widely as a result of numerous factors beyond our control. The effect of these factors on the price of gold and silver, and therefore the economic viability of our projects, cannot accurately be predicted. Any drop in the price of gold or silver would negatively affect our asset values, cash flows, potential revenues and profits.

The use of hedging instruments may not prevent losses being realized on subsequent price decreases or may prevent gains being realized from subsequent price increases.

We may from time to time sell some future production of gold pursuant to hedge positions. If the gold price rises above the price at which future production has been committed under these hedge instruments, we will have an opportunity loss. If the gold price falls below that committed price, we may experience losses if a hedge counterparty defaults under a contract when the contract price exceeds the gold price. As of December 31, 2017 , we have no open hedge positions.

We compete with other mineral exploration and mining companies which could lead to the loss of opportunities.

We compete with other mineral exploration and mining companies or individuals, including large, established mining companies with substantial capabilities and financial resources, to acquire rights to mineral properties containing gold and other minerals. There is a limited supply of desirable lands available for claim staking, lease or other acquisition. There can be no assurance that we will be able to acquire such properties when competing against competitors with substantially greater financial resources than we have.

The estimation of the ultimate recovery of gold and silver is subjective. Actual recoveries may vary from our estimates.

We utilize the heap leach process to extract gold and silver from mineralized material. The heap leach process extracts gold and silver by placing mineralized material on an impermeable pad and applying a diluted cyanide solution that dissolves a portion of the contained gold and silver, which are then recovered in metallurgical processes. We use several integrated steps in the process of extracting gold and silver to estimate the metal content of the mineralized material placed on the leach pad. The final amounts are not determined until a third-party smelter converts the doré and determines final ounces of gold and silver available for sale. We then review this end result and reconcile it to the estimates we developed and used throughout the production process. Based on this review, we adjust our estimation procedures when appropriate. Due to the complexity of the estimation process and the number of steps involved, among other things, actual recoveries can vary from estimates, and the amount of the variation could be significant and could have a material adverse impact on our financial condition and results of operations.

Resource and other mineralized material statements are estimates only, and are subject to uncertainty due to factors including metal prices, inherent variability of the mineralized material and recoverability of metal in the mining process.

Our reports of mineral resources, other mineralized material and grading are estimates and depend upon geological interpretation and statistical inferences or assumptions drawn from drilling and sampling analysis, which may prove to be unpredictable. There is a degree of uncertainty attributable to the calculation of mineral resources and corresponding grades. Until mineral resources and other mineralized materials are actually mined and processed, the quantity of mineralized material

and grades must be considered as an estimate only. In addition, the quantity of mineral resources and other mineralized materials may vary depending on metal prices. Any material change in the quantity of mineral resources, other mineralized materials, mineralization, grade or stripping ratio may affect the economic viability of our properties. In addition, we can provide no assurance that gold recoveries or other metal recoveries experienced in small-scale laboratory tests will be duplicated in larger scale tests under on-site conditions or during production.

Our mining production depends on the availability of sufficient water supplies.

Our mining operations require significant quantities of water for mining, processing and related support facilities. Most of our mining operations are in areas where water is scarce and competition among users for continuing access to water is significant. Continuous production at our mines is dependent on our ability to maintain our water rights and claims, and the continuing physical availability of the water supplies.

Cost estimates and timing of new projects are uncertain, which may adversely affect our expected production and profitability.

The capital expenditures and time required to develop and explore our properties, including the Lucerne Mine and Dayton resource areas, are considerable and changes in costs, construction schedules or both, can adversely affect project economics and expected production and profitability. There are a number of factors that can affect costs and construction schedules, including, among others:


•	availability of labor, energy, transportation, equipment, and infrastructure;


•	changes in input commodity prices and labor costs;


•	fluctuations in currency exchange rates;


•	availability and terms of financing;


•	changes in anticipated tonnage, grade and metallurgical characteristics of the mineralized material to be mined and processed;


•	recovery rates of gold and other metals from the mineralized material;


•	difficulty of estimating construction costs over a period of a year;


•	delays in completing any environmental review or in obtaining environmental or other government permits;


•	weather and severe climate impacts; and


•	potential delays related to social, political and community issues.

We may experience increased costs or losses resulting from the hazards and uncertainties associated with mining.

The exploration for natural resources and the development and production of mining operations are activities that involve a high level of uncertainty. These can be difficult to predict and are often affected by risks and hazards outside of our control. These factors include, but are not limited to:


•	environmental hazards, including discharge of metals, concentrates, pollutants or hazardous chemicals;


•	industrial accidents, including in connection with the operation of mining transportation equipment, milling equipment and/or conveyor systems and accidents associated with the preparation and ignition of large-scale blasting operations, milling, processing and transportation of chemicals, explosives or other materials;


•	surface or underground fires or floods;


•	unexpected geological formations or conditions (whether in mineral or gaseous form);


•	ground and water conditions;


•	fall-of-ground accidents in underground operations;


•	failure of mining pit slopes and tailings dam walls;


•	seismic activity; and


•	other natural phenomena, such as lightning, cyclonic or tropical storms, floods or other inclement weather conditions.

Our activities are inherently hazardous and any exposure may exceed our insurance limits or may not be insurable.

Mineral exploration and operating activities are inherently hazardous. Operations in which we have direct or indirect interests will be subject to all the hazards and risks normally incidental to exploration and production of gold and other metals, any of which could result in work stoppages, damage to property and possible environmental damage. The nature of these risks is such that liabilities might exceed any applicable liability insurance policy limits. It is also possible that the liabilities and hazards might not be insurable, or we could elect not to insure ourselves against such liabilities because of the high premium costs, in which event, we could incur significant costs that could have a material adverse effect on our financial condition.

Our ability to execute our strategic plans depends upon our success in obtaining a variety of required governmental approvals that may be opposed by third-parties.

We do not possess all of the governmental approvals necessary to conduct the full extent of the operations contemplated by our strategic plan. Those operations will be delayed, hindered or prevented to the extent that we are unable to obtain the necessary permits and approvals in a timely fashion or at all. This inability may occur due to a variety of factors, including opposition by third parties, such as members of the public or environmental groups. We expect that future permit and approval applications and issuances will meet with similar opposition. We may encounter delays and added costs if permits and approvals are challenged.

Mining companies are increasingly required to consider and provide benefits to the communities in which they operate.

As a result of public concern about the real or perceived detrimental effects of economic globalization and global climate impacts, businesses generally, and corporations in natural resource industries, face increasing public scrutiny of their activities. These businesses are under pressure to demonstrate that, as they seek to generate satisfactory returns on investment to shareholders, other stakeholders, including employees, governments, and communities surrounding operations benefit and will continue to benefit from their commercial activities. Such pressures tend to be particularly focused on companies whose activities are perceived to have a high impact on their social and physical environment. The potential consequences of these pressures include reputational damage, legal suits, increasing social investment obligations and pressure to increase taxes and royalties payable to governments and communities.

Our operations are subject to strict environmental laws and regulations, which could result in added costs of operations and operational delays.

Our operations are subject to strict environmental regulations, which could result in additional costs and operational delays. All phases of our operations are subject to environmental regulation. Environmental legislation is evolving in the United States generally, and Nevada specifically, in a manner that may require stricter standards and enforcement, increased fines and penalties for non-compliance, more stringent environmental assessments of proposed projects, and a heightened degree of responsibility for companies and their officers, directors, and employees. There is no assurance that any future changes in environmental regulation will not negatively affect our projects.

At the state level, mining operations in Nevada are regulated by the Nevada Division of Environmental Protection ("NDEP"). Nevada state law requires our Nevada projects to hold Nevada water pollution control permits, which dictate operating controls and closure and post-closure requirements directed at protecting surface and ground water. In addition, we are required to hold Nevada reclamation permits required under Nevada law. These permits mandate concurrent and post-mining reclamation of mines and require the posting of reclamation bonds sufficient to guarantee the cost of mine reclamation. Other Nevada regulations govern operating and design standards for the construction and operation of any source of air contamination and landfill operations. Any changes to these laws and regulations could have a negative impact on our financial performance and results of operations by, for example, requiring changes to operating constraints, technical criteria, fees or surety requirements.

Regulations and pending legislation governing issues involving climate change could result in increased operating costs which could have a material adverse effect on our business .

Our business is an energy-intensive undertaking, resulting in a significant carbon footprint. A number of governments or governmental bodies have introduced or are contemplating regulatory changes in response to the potential impacts of climate change that are viewed as the result of emissions from the combustion of carbon-based fuels. Legislation and increased regulation and requirements regarding climate change could impose increased costs on us and our suppliers, including increased energy, capital equipment, environmental monitoring and reporting and other costs to comply with such regulations. Until the timing, scope and extent of any future requirements becomes known, we cannot predict the effect on our financial condition, financial position, results of operations and ability to compete.

Because our land holdings are within the Carson River Mercury Superfund Site, our operations are subject to certain soil sampling and potential remediation requirements, which may result in added costs and delays; and we are also potentially subject to further costs as the result of on-going government investigation and future remediation decisions.

Substantially all of our land holdings are within the Carson River Mercury Superfund Site (CRMS) Study Area and portions are within the risk area boundaries identified by NDEP and the United States Environmental Protection Agency (USEPA). These risk areas have been defined due to the known or suspected presence of certain contaminants of concern, including mercury, arsenic and lead. To comply with the agencies’ requirements in these areas, the Company conducts soil sampling pursuant to a plan that has been approved by NDEP. This sampling is intended to demonstrate the absence of contamination before mining, processing or other operations in that area. If contamination above agency-established levels of concern is encountered, the Company intends to excavate and process such materials for metals recovery wherever feasible. If metals recovery is not feasible, the Company may avoid or defer excavating in that area, remove the materials for disposal, or cover the area with clean fill material. Through this sampling program and, if necessary, removal of contaminated materials, the Company intends to enable NDEP and USEPA to better define the Carson River Superfund Site and the currently designated risk areas so as to eventually exclude our land holdings from such areas and from the Site itself to the maximum extent feasible. NDEP and USEPA are continuing to study the ecological and human health risks that may be presented by contaminated sediments in certain portions of the Carson River watershed and downstream areas. The agencies’ studies indicate that these contaminants are primarily associated with historic mining tailings that have been redistributed into these waterways. The agencies have not adopted a remedial plan for these sediments nor have they decided whether remediation will be undertaken. Thus, there is no assurance that the Company will not be asked to undertake additional investigatory or remediation activities or to pay for such activities by the agencies or that future changes in CRMS-related requirements will not negatively affect our operations.

Our insurance and surety bonds for environmental-related issues are limited.

Our insurance and surety bonds against environmental risks are limited as to the maximum protection against potential liability for pollution or other hazards as a result of the disposal of waste products occurring from exploration and production. Further, there is no assurance that insurance carriers or surety bond providers will be able to meet their obligations under our arrangements with them. In the event that our environmental liabilities and costs exceed the coverage provided by our insurance carriers and surety bond providers or such parties are unable to meet their obligations, we would have limited funds available to us to remedy such liabilities or costs or for future operations. If we are unable to fund the cost of remedying an environmental problem, we also might be required to enter into an interim compliance measure pending completion of the required remedy.

We are subject to federal and state laws that require environmental assessments and the posting of bonds, which add significant costs to our operations and delays in our projects.

Mining companies must post a bond or other surety to guarantee the cost of post-mining reclamation. These requirements could add significant additional cost and delays to any mining project undertaken by us. Our mineral exploration operations are required to be covered by reclamation bonds deemed adequate by regulators to cover these risks.

BLM requires that mining operations on lands subject to its regulation obtain an approved plan of operations subject to environmental impact evaluation under the National Environmental Policy Act ("NEPA"). Any submission or significant modification to a plan of operations may also require the completion of an environmental assessment or Environmental Impact Statement ("EIS") prior to approval.

The Company’s costs of close- down, reclamation and rehabilitation could be higher than expected.

Close-down and reclamation works to return operating sites to the community can be extensive and costly. Estimated costs are provided for, and updated annually, over the life of each operation but the provisions might prove to be inadequate due to changes in legislation, standards and the emergence of new, or increases in the cost of, reclamation techniques. In addition, the expected timing of expenditure could change significantly due to changes in the business environment that might vary the life of an operation.

We may be subject to litigation.

We may be subject to legal proceedings. Due to the nature of our business, we may be subject to a variety of regulatory investigations, claims, lawsuits and other proceedings in the ordinary course of our business. The results of these legal proceedings cannot be predicted with certainty due to the uncertainty inherent in litigation, including the effects of discovery of new evidence or advancement of new legal theories, the difficulty of predicting decisions of judges and juries and the possibility that decisions may be reversed on appeal. There can be no assurances that these matters will not have a material adverse effect on our business.

Title claims against our properties could require us to compensate parties making such claims, if successful, and divert management’s time from operations.

There may be challenges to our title in the properties in which we hold material interests. If there are title defects with respect to any of our properties, we might be required to compensate other persons or perhaps reduce our interest in the affected property. The validity of unpatented mineral claims, which constitute most of our holdings in the United States, is often uncertain and may be contested by the federal government and other parties. The validity of an unpatented mineral claim, in terms of both its location and its maintenance, depends on strict compliance with a complex body of federal and state, statutory and decisional law. Although we have attempted to acquire satisfactory title to our properties, we have not obtained title opinions or title insurance with respect to the acquisition of the unpatented mineral claims. The investigation and resolution of title issues would divert management’s time from ongoing exploration programs.

Our business depends on a limited number of key personnel, the loss of whom could negatively affect us.

Our officers and employees are important to our success. If any of them becomes unable or unwilling to continue in their respective positions, and we are unable to find suitable replacements, our business and financial results could be materially negatively affected.

Our business may be adversely affected by information technology disruptions.

Cybersecurity incidents are increasing in frequency, evolving in nature and include, but are not limited to, installation of malicious software, unauthorized access to data and other electronic security breaches that could lead to disruptions in systems, unauthorized release of confidential or otherwise protected information and the corruption of data. We believe that we have implemented appropriate measures to mitigate potential risks. However, given the unpredictability of the timing, nature and scope of information technology disruptions, we could be subject to manipulation or improper use of our systems and networks or financial losses from remedial actions, any of which could have a material adverse effect on our financial condition and results of operations.

We rely on contractors to conduct a significant portion of our operations and construction projects.

A significant portion of our operations and construction projects are currently conducted in whole or in part by contractors. As a result, our operations are subject to a number of risks, some of which are outside our control, including:


•	negotiating agreements with contractors on acceptable terms;


•	the inability to replace a contractor and its operating equipment in the event that either party terminates the agreement;


•	reduced control over those aspects of operations which are the responsibility of the contractor;


•	failure of a contractor to perform under its agreement;


•	interruption of operations or increased costs in the event that a contractor ceases its business due to insolvency or other unforeseen events;


•	failure of a contractor to comply with applicable legal and regulatory requirements, to the extent it is responsible for such compliance; and


•	problems of a contractor with managing its workforce, labor unrest or other employment issues.

In addition, we may incur liability to third parties as a result of the actions of our contractors. The occurrence of one or more of these risks could adversely affect our results of operations and financial position.

Our business requires substantial capital investment and we may be unable to raise additional funding on favorable terms.

The construction and operation of potential future projects and various exploration projects will require significant funding. Our operating cash flow and other sources of funding may become insufficient to meet all of these requirements, depending on the timing and costs of development of these and other projects. As a result, new sources of capital may be needed to meet the funding requirements of these investments and fund our ongoing business activities. Our ability to raise and service significant new sources of capital will be a function of macroeconomic conditions, future gold and silver prices, our operational performance and our current cash flow and debt position, among other factors. In the event of lower gold and silver prices, unanticipated operating or financial challenges, or a further dislocation in the financial markets as experienced in recent years, our ability to pursue new business opportunities, invest in existing and new projects, fund our ongoing operations and retire or service all of our outstanding debt could be significantly constrained.

We may not be successful in selling off non-mining related assets.

Our short-term plans include the sale of non-core, non-strategic, non-mining assets. The success of these plans depends on the market prices and demand for the purchase of such assets. We may not be able to generate sufficient funds from the sale of these assets to pay off our indebtedness or offset our other liquidity needs.

Our substantial indebtedness and payment obligations could adversely affect our operations, financial condition, cash flow, and operating flexibility.

Our significant amount of outstanding indebtedness and lease payment obligations, and the covenants contained in our debt agreements and documents governing such obligations could have a material adverse effect on our operations and financial condition. The size and terms of certain of our agreements limits our ability to obtain additional debt financing to fund future working capital, acquisitions, capital expenditures, engineering and product development costs, and other general corporate requirements. Other consequences for our operations could include:


•	making it more difficult for us to satisfy our obligations with respect to our other indebtedness, which could in turn result in an event of default on such other indebtedness;


•	impairing our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, general corporate purposes or other purposes;


•	requiring us to dedicate a substantial portion of our cash flow from operations to debt service payments, thereby reducing the availability of cash for working capital, capital expenditures, acquisitions, general corporate purposes or other purposes;


•	limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate; and


•	placing us at a competitive disadvantage compared to our competitors that have proportionately less debt.

Our ability to make required payments of principal and interest on our debt will depend on our future performance and the other cash requirements of our business. Our performance is subject to general economic, political, financial, competitive, and other factors that are beyond our control in addition to challenges that are unique to the Company. We cannot provide any assurance that our business will generate sufficient cash flow from operations or that future borrowings will be available in an amount sufficient to enable us to service our indebtedness and lease obligations.

Our debt and lease agreements contain certain restrictive covenants and customary events of default. These restrictive covenants limit our ability to take certain actions, such as, among other things: make restricted payments; incur additional debt and issue certain preferred stock; create liens; engage in mergers or consolidations or transfer all or substantially all of our assets; make certain dispositions and transfers of assets; place limitations on the ability of our restricted subsidiaries to make distributions; enter into transactions with affiliates; and guarantee indebtedness. One or more of these restrictive covenants may limit our ability to execute our preferred business strategy, take advantage of business opportunities, or react to changing industry conditions.

Upon an event of default, if not waived by our financing parties, our financing parties may declare all amounts outstanding as due and payable, which may cause cross-defaults under our other obligations. If our current financing parties accelerate the maturity of our indebtedness or obligations, we may not have sufficient capital available at that time to pay the amounts due to our financing parties on a timely basis, and there is no guarantee that we would be able to repay, refinance, or restructure the payments on such debt and lease obligations. Further, the financing parties would have the right to foreclose on certain of our assets, which could have a material adverse effect on our Company.

Our stock is a penny stock and trading of our stock may be restricted by the SEC’s penny stock regulations, which may limit a stockholder’s ability to buy and sell our stock.

Our stock is a penny stock. Rule 3a51-1 generally defines “penny stock” to be any equity security that has a market price (as defined) less than $5.00 per share or an exercise price of less than $5.00 per share, subject to certain exceptions. Our securities are covered by the penny stock rules, which impose additional sales practice requirements on broker-dealers that sell to persons other than established customers and “accredited investors.” The term “accredited investor” refers generally to institutions with assets in excess of $5,000,000 or individuals with a net worth in excess of $1,000,000 (excluding one’s primary residence) or annual income exceeding $200,000 individually or $300,000 jointly with their spouse. The penny stock rules (including Rule 15g-9) require a broker-dealer, prior to a transaction in a penny stock not otherwise exempt from the rules, to deliver a standardized risk disclosure document in a form prepared by the SEC, which provides information about penny stocks and the nature and level of risks in the penny stock market. The broker-dealer also must provide the customer with current bid and offer quotations for the penny stock, the compensation of the broker-dealer and its salesperson in the transaction, and monthly account statements showing the market value of each penny stock held in the customer’s account. The bid and offer quotations, and the broker-dealer and salesperson compensation information, must be given to the customer orally or in writing prior to effecting the transaction and must be given to the customer in writing before or with the customer’s confirmation. In addition, the penny stock rules require that, prior to a transaction in a penny stock not otherwise exempt from these rules, the broker-dealer must make a special written determination that the penny stock is a suitable investment for the purchaser and receive the purchaser’s written agreement to the transaction. These disclosure requirements may have the effect of reducing the level of trading activity in the secondary market for the stock that is subject to these penny stock rules. Consequently, these penny stock rules may affect the ability of broker-dealers to trade our securities. We believe that the penny stock rules discourage investor interest in and limit the marketability of our common stock. The Financial Industry Regulatory Authority (FINRA) sales practice requirements may also limit a stockbroker’s ability to buy or sell our stock.

In addition to the “penny stock” rules promulgated by the SEC, FINRA has adopted rules that require that in recommending an investment to a customer, a broker-dealer must have reasonable grounds for believing that the investment is suitable for that customer. Prior to recommending speculative low priced securities to their non-institutional customers, broker-dealers must make reasonable efforts to obtain information about the customer’s financial status, tax status, investment objectives, and other information. Under interpretation of these rules, FINRA believes that there is a high probability that speculative low priced securities will not be suitable for at least some customers. The FINRA requirements make it more difficult for broker-dealers to recommend that their customers buy our common stock, which may limit your ability to buy or sell our stock and have an adverse effect on the market for our shares.

If we are unable to maintain the listing standards of the NYSE American, our common stock may be delisted, which may have a material adverse effect on the liquidity and value of our common stock.

Our common stock is traded on the NYSE American. To maintain our listing on the NYSE American, we must meet certain financial and liquidity criteria. The market price of our common stock has been and may continue to be subject to significant fluctuation as a result of periodic variations in our revenues and results of operations. If we fail to meet any of the NYSE American’s listing standards, we may be delisted. In the event of delisting, trading of our common stock would most likely be conducted in the over the counter market on an electronic bulletin board established for unlisted securities, which could have a material adverse effect on the market liquidity and value of our common stock.

The price of the Company’s common stock may fluctuate significantly, which could negatively affect the Company and holders of its common stock.

The market price of the Company’s common stock may fluctuate significantly from time to time as a result of many factors, including:


•	investors’ perceptions of the Company and its prospects;


•	investors’ perceptions of the Company’s and/or the industry’s risk and return characteristics relative to other investment alternatives;


•	investors’ perceptions of the prospects of the mining and commodities markets;


•	difficulties between actual financial and operating results and those expected by investors and analysts;


•	our inability to obtain permits or otherwise fail to reach Company objectives;


•	changes in our capital structure;


•	trading volume fluctuations;


•	actual or anticipated fluctuations in quarterly financial and operational results;


•	volatility in the equity securities market; and


•	sales, or anticipated sales, of large blocks of the Company’s common stock.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us or our business. We have relatively little research coverage by securities and industry analysts. If no additional industry analysts commence coverage of the Company, the trading price for our common stock could be negatively impacted. If one or more of the analysts who cover us downgrades our common stock or publishes inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, demand for our common stock could decrease, which could cause our stock price and trading volume to decline.

We do not expect to pay any cash dividends for the foreseeable future.

We currently expect to retain all available funds and future earnings, if any, for use in the operation and growth of our business and do not anticipate paying any cash dividends in the foreseeable future. Any future determination to pay cash dividends will be at the discretion of our Board, subject to compliance with applicable law, our organizational documents and any contractual provisions, including under agreements for indebtedness we may incur, that restrict or limit our ability to pay dividends, and will depend upon, among other factors, our results of operations, financial condition, earnings, capital requirements and other factors that our Board deems relevant. Investors seeking cash dividends in the foreseeable future should not purchase our common stock.

The concentrated beneficial ownership of our common stock and the ability it affords to control our business may limit or eliminate other shareholders' ability to influence corporate affairs.

Based on filings made with the SEC, Mr. John V. Winfield, and entities that he controls (the “Winfield Group”) own 10,135,648 shares of the Company’s common stock, or 20.4% . Separately, Van Den Berg Management, Inc. owns 5,588,077 shares of the Company’s common stock, or 11.2% . Because of this concentrated stock ownership, the Company’s largest shareholders could be in a position to significantly influence the election of our board of directors and all other decisions on all matters requiring shareholder approval. As a result, the ability of other shareholders to determine the management and policies of the Company is significantly limited. The interests of these shareholders may differ from the interests of other shareholders with respect to the issuance of shares, business transactions with or sales to other companies, selection of officers and directors and other business decisions. This level of control may also have an adverse impact on the market value of our shares because our largest shareholders may institute or undertake transactions, policies or programs that may result in losses, may not take any steps to increase our visibility in the financial community and/or may sell sufficient numbers of shares to significantly decrease our price per share.

Restrictions imposed by the 2015 Stockholders' Agreement may inhibit growth.

The 2015 Stockholders’ Agreement limits the ability of the Company to incur debt, among other things. Such restrictions could significantly impact the Company’s ability to take certain actions that potentially could enhance shareholder value. Refer to Part III, Item 13 for more information about the Stockholder’s Agreement.

The terms of the Operating Agreement of Northern Comstock LLC require significant cash payments and may significantly dilute the ownership interests of the common stock.

The Operating Agreement of Northern Comstock LLC requires that the Company make monthly cash capital contributions of $30,000 to Northern Comstock LLC and annual capital contributions in the amount of $482,500 payable in common stock or cash, at the Company's option, unless the Company has cash and cash equivalents in excess of $10,500,000 on the date of such payments, wherein the Company would then be required to pay in cash. The number of shares to be delivered is calculated by dividing the amount of the capital contribution by the volume-weighted average closing price of the Company’s common stock on its primary trading market for the previous 20 consecutive trading days prior to such capital contribution. The Operating Agreement also provides for a one-time acceleration of $812,500 of the capital contributions payable when the Company receives net cash proceeds from sources other than operations that exceed $6,250,000. The agreement also includes an ongoing acceleration of the Company’s capital contribution obligations equal to 3% of the net smelter returns generated by the properties subject to the Northern Comstock LLC joint venture. The Operating Agreement also provides that if the Company defaults in its obligation to make the scheduled capital contributions, then the remaining capital contribution obligations may be converted into the principal amount of a 6% per annum promissory note payable by the Company on the same schedule as the capital contributions, secured by a mortgage on the properties subject to the Northern

Comstock LLC joint venture. The Operating Agreement requires that the remaining capital contributions, totaling $7.95 million at December 31, 2017 continue until September 2027, unless prepaid by the Company.

The Company may issue additional common stock or other equity securities in the future that could dilute the ownership interest of existing stockholders.

The Company is currently authorized to issue 790,000,000 shares of common stock, of which 47,236,103 shares were issued and outstanding as of December 31, 2017 , and 50,000,000 shares of preferred stock, of which no Preferred Shares are issued or outstanding as of the December 31, 2017 . To maintain its capital at desired levels or to fund future growth, the Board may decide from time to time to issue additional shares of common stock, or securities convertible into, exchangeable for or representing rights to acquire shares of common stock. The sale of these securities may significantly dilute stockholders’ ownership interest and the market price of the common stock. New investors in other equity securities issued by the Company in the future may also have rights, preferences and privileges senior to the Company’s current stockholders that may adversely impact its current stockholders.

We have made and may in the future pursue investments in other companies, which could harm our operating results.

We have made, and could make in the future, investments in other companies, including privately-held companies in a development stage. Many of these private equity investments are inherently risky because the companies’ businesses may never develop, and we may incur losses related to these investments. In addition, we may be required to write down the carrying value of these investments to reflect other-than-temporary declines in their value, which could have a material adverse effect on our financial position and results of operations.

We may pursue acquisitions, divestitures, business combinations, joint ventures or other transactions with other companies, involving our properties or new properties, which could harm our operating results, may disrupt our business and could result in unanticipated accounting charges.

Acquisitions of other companies or new properties, divestitures, business combinations, joint ventures or other transactions with other companies may create additional, material risks for our business that could cause our results to differ materially and adversely from our expected or projected results. Such risk factors include the effects of possible disruption to the exploration activities and mine planning, loss of value associated with our properties, mismanagement of project development, additional risk and liability, indemnification obligations, sales of assets at unfavorable prices, poor execution of the strategic plan for the transaction, permit requirements, debt incurred or capital stock issued to enter into such transactions, the impact of any such transactions on our financial results, negative stakeholder reaction to any such transaction and our ability to successfully integrate an acquired company’s operations with our operations. If the purchase price of any acquired businesses exceeds the current fair values of the net tangible assets of such acquired businesses, we would be required to record material amounts of goodwill or other intangible assets, which could result in significant impairment and amortization expense in future periods. These charges, in addition to the results of operations of such acquired businesses and potential restructuring costs associated with an acquisition, could have a material adverse effect on our business, financial condition and results of operations. We cannot forecast the number, timing or size of future transactions, or the effect that any such transactions might have on our operating or financial results. Furthermore, potential transactions, whether or not consummated, will divert our management’s attention and may require considerable cash outlays at the expense of our existing operations. In addition, to complete future transactions, we may issue equity securities, incur debt, assume contingent liabilities or have amortization expenses and write-downs of acquired assets, which could adversely affect our profitability.

Diversity in application of accounting literature in the mining industry may impact our reported financial results.

The mining industry has limited industry-specific accounting literature and, as a result, we understand diversity in practice exists in the interpretation and application of accounting literature to mining-specific issues. As diversity in mining industry accounting is addressed, we may need to restate our reported results if the resulting interpretations differ from our current accounting practices. See Note 2 to the Consolidated Financial Statements for a summary of our significant accounting policies.

Item 2. Properties

The Comstock District

Location, Access, and Title to the Property

The Company and its subsidiaries own or control property located in Storey and Lyon Counties, Nevada. The property is located predominantly in the Comstock and Silver City districts, just south of Virginia City, Nevada. Paved state routes from Reno, Carson City, and Virginia City provide access to the property. The Comstock District has been the focus of our efforts since 2003.

Our mineral estate in the Comstock District and surrounding area consists of patented mining claims, unpatented mining claims administered by the BLM, five mineral leases, one joint venture (providing exclusive rights to exploration, development, mining and production), and fee ownership of real property. This includes 110 patented and 382 unpatented mineral lode claims, as well as 39 unpatented placer claims. The Company holdings consist of approximately 9,272 acres of mining claims and parcels. The acreage is comprised of approximately 2,347 acres of patented claims (private lands) and surface parcels (private lands), and approximately 6,925 acres of unpatented mining claims that the BLM administers.

Figure 2 - Comstock Mining's Property and Mineral Leases in the Comstock District

The Company holds the following mineral leases, as shown in Figure 2:

Fred Garrett - Lease

On April 1, 2008, we entered into a mineral exploration and mining lease agreement with Fred Garrett et al, covering one patented claim located in Storey County, Nevada. The lease remains in effect as long as exploration, development, mining, or processing operations are being conducted on a continuous basis, without a lapse of activity for more than 180 days. We pay a royalty to the lessor of $250 per month or a 3% net smelter royalty (“NSR”), whichever is greater. We are responsible for the payment and filing of annual maintenance fees, if any, and taxes for these claims.

James Obester Lease

On August 1, 2008, we entered into a mineral exploration and mining lease agreement with James Obester, covering ten unpatented claims located in Storey County. The lease remains in effect as long as exploration, development, mining, or processing operations are conducted on a continuous basis, without a lapse of activity of more than 180 days. We pay a royalty to the lessor amounting to $200 per month for the first two years and later increasing to $300 per month for the following three years, and then increasing to $500 per month thereafter. In addition, a NSR royalty percentage is applicable. The royalty percentage is a 2% NSR when the market price of gold is $900 or less per ounce and 3% NSR when gold is greater than $900 per ounce. We are also responsible for payment and filing of annual maintenance fees, if any, and taxes for these claims.

Railroad & Gold - Lease

On October 1, 2009, we entered into a mineral exploration and mining lease agreement with Railroad and Gold, LLC covering nine patented mining claims and sixteen unpatented mining claims in Storey County. The lease also includes rights for nine town lots and a rural parcel in American Flats. The lease is for an initial term of 15 years, but remains in effect for as long as exploration, development, mining, or processing operations are conducted on a continuous basis. We made an initial payment of $25,000 for the lease. The Company makes annual advance minimum royalty payments, which started with $30,000 on the first anniversary, and increasing by $5,000 each year. We are also required to pay a 4% NSR, which will be reduced by the sum of previously paid advance minimum royalties. We are also responsible for payment and filing of annual maintenance fees, if any, and taxes for these claims. Effective January 1, 2016, the royalty was reduced to 1% NSR in exchange for 24 monthly payments of $2,083. Additionally, starting January 1, 2016, the annual payment on the lease was reduced for 2016 to $18,000 per year and $20,400 per year in 2017 and 2018.

New Daney - Lease

On June 2, 2010, we entered into a mineral exploration and mining lease agreement with New Daney Company, Inc. covering seven unpatented lode claims. These claims are located in Lyon County and are contiguous with the Company’s Spring Valley mineral holdings. All production from the property is subject to a 3% NSR. Once permits have been obtained to put the property into production, lease payments will be treated as advance royalties, which will be credited against the NSR. The Company makes advance minimum royalty payments of $200 per month. The lease is for an initial term of five years. We have the option, if we believe the property warrants further development, to extend an additional five years and then continuously thereafter as long as exploration, development, mining, or processing operations are conducted on a continuous basis. The lease was amended December 18, 2015 to extend the lease through 2020, and to include an option to purchase the claims, including the NSR, for $100,000.

Renegade Mineral Holdings - Lease

On October 14, 2010, we acquired twenty-six unpatented lode-mining claims along the southern extension of the Occidental Lode structure in Storey County, Nevada. The historic Occidental Lode, also referred to as the Brunswick Lode, is located 1.5 miles due east of and sub-parallel to the veins of the main Comstock Lode. These claims adjoined and extended the Company’s previous holdings of six patented and six unpatented claims, significantly expanding the Company’s position on the Occidental Lode. The Lease has an initial term of three years and, in the event we determine that exploration results warrant further development, then the term can be extended initially for two additional six-year terms and then continuously thereafter as long as the Company is producing on property adjacent to or in the vicinity of these claims. The agreement includes a 3% NSR from production with the gold price capped at $2,000 per ounce. We are also responsible for payment and filing of annual maintenance fees, if any, and taxes for these claims. The lease was amended in October 2013 to formally extend the lease for the first additional six-year term. The lease still provides for a second additional six-year term, and then continuously thereafter.

Northern Comstock LLC- Joint Venture

On October 20, 2010, the Company entered into an operating agreement (the “Operating Agreement”) to form Northern Comstock LLC (“Northern Comstock”) with Mr. Winfield, our largest shareholder, and an entity controlled by Mr. Winfield, DWC Resources, Inc. (“DWC”). As part of the Operating Agreement, the Company obtained rights relating to certain property formerly owned by DWC in Storey County, Nevada (the “DWC Property”) and two groups of properties leased by Mr. Winfield in Storey County, Nevada from the Sutro Tunnel Company (the “Sutro Property”) and Virginia City Ventures (the “VCV Property”).

Pursuant to the terms of the Operating Agreement for Northern Comstock, DWC contributed the DWC Property to Northern Comstock and John Winfield contributed his rights under the Sutro and the VCV leases to Northern Comstock. The Company contributed 862.5 shares of Series A-1 Preferred Stock in each annual period from 2010 to 2013, and contributes its services in the area of mine exploration, development and production to Northern Comstock. The terms of the Operating Agreement provided that on each anniversary of the Operating Agreement, up to and including the thirty-ninth (39 ^th ) anniversary, the Company would make additional capital contributions in the amount of $862,500, in the form of Series A-1 Preferred Stock or cash (upon request of Northern Comstock, which request for cash can be denied by the Company in certain circumstances).

On August 27, 2015, the Company signed an Amendment to the Operating Agreement with Northern Comstock LLC. The Amendment resulted in reduced capital contribution obligations of the Company from $31.05 million down to $9.75 million. The Operating Agreement requires that the Company make monthly cash capital contributions of $30,000 to Northern Comstock LLC and annual capital contributions in the amount of $482,500 payable in stock or cash, at the Company's option, unless the Company has cash and cash equivalents in excess of $10,500,000 on the date of such payments, wherein the Company would then be required to pay in cash. The number of shares to be delivered is calculated by dividing the amount of the capital contribution by the volume-weighted average closing price of the Company’s common stock on its primary trading market for the previous 20 consecutive trading days prior to such capital contribution. The Operating Agreement also provides for a one-time acceleration of $812,500 of the capital contributions payable when the Company receives net cash proceeds from sources other than operations that exceed $6,250,000. The agreement also includes an ongoing acceleration of the Company’s capital contribution obligations equal to 3% of the net smelter returns generated by the properties subject to the Northern Comstock joint venture. The Operating Agreement also provides that if the Company defaults in its obligation to make the scheduled capital contributions, then the remaining capital contribution obligations may be converted into the principal amount of a 6% per annum promissory note payable by the Company on the same schedule as the capital contributions, secured by a mortgage on the properties subject to the Northern Comstock joint venture. The Operating Agreement requires that these capital contributions commence in October 2015, and end in September 2027, unless prepaid by the Company.

The Operating Agreement provides the Company with the exclusive rights of development, production, mining and exploration on the respective properties and requires the Company to make certain expenditures toward that end. Under the terms of the Operating Agreement, all cash flows from the bullion or other minerals recovered from the ore mined out of the ground but untreated and minerals produced from the milling or reduction of ore to a higher grade produced from the DWC Property, Sutro Property or VCV Property, as applicable, or finished products produced from any such property, will be distributed to the Company after the payment of royalties associated with such properties.

Mineral production from the DWC Property is subject to a 1% NSR royalty payable to Mr. Art Wilson. Mineral production on the Sutro Property is subject to a royalty of 5% NSR. Mineral production from the VCV Property is subject to a 5% NSR royalty. The Company makes advance minimum royalty payments of $1,000 per month on the Sutro Property and $6,000 per year on the VCV Property leases. Each lease is for an initial term of five years. We have the option, if we believe the property warrants further development, to extend an additional five years and then continuously thereafter as long as exploration, development, mining, or processing operations are conducted on a continuous basis.

Facilities Area

The heap leach facility and former Company headquarters originally occupied a 40-acre site in Storey County, Nevada, at 1200 American Flat Road, approximately three miles south of Virginia City and 30 miles southeast of Reno, Nevada. The property was included in the acquisition of Plum Mining by the Company in November 2003. The site has expanded, through land acquisitions, to 400 acres. The Company’s headquarters is at our Corporate Campus at 117, 119 and 123 American Flat Road in Gold Hill, Nevada, covering a 5-acre parcel. Our mining and reclamation operations have taken place over a nearly 100-acre area.

New Claims

The Company completed a study of lands open to mineral entry near the Company's Dayton resource area and Spring Valley exploration targets. Thirty lode claims were located, perfected and filed with Lyon County and the Bureau of Land Management in 2017. The recently staked lode claims were positioned adjacent to the Company’s Wonder and Amazon patents, to control lands hosting favorable geology and provide an additional contiguous corridor to our northern land holdings located west of State Route 341. The block of new claims adds approximately 470 net acres to the Company's already significant land position in the historic Comstock District. Exploration efforts can now be expanded to include the new, adjacent claims.

The Como Project

The Como Project is located in Lyon County, Nevada, approximately 15 miles east of Carson City. The Company performed geological reconnaissance on this property, but has not drilled or collected any samples. We own a 100% interest in eight unpatented lode-mining claims, covering an area of approximately 168 acres in Lyon County, Nevada, that comprise the Como Project.

Present Condition of Property and Work Performed

We have completed extensive geological mapping, sampling, and drilling on a limited portion of the Comstock District mineral property, particularly the Lucerne and Dayton resource areas, in order to characterize the mineralized material. We have performed metallurgical testing, mine planning, and economic analysis, and have produced internal reports of our mineralized material inventory. We conducted test mining operations from 2004 through 2006 and from 2012 through 2016. However, we have not established reserves that meet the requirements of SEC Industry Guide 7. Therefore, any activities that we perform on our lands and claims are considered exploratory in nature, including test mining.

Geology, Structure and Mineralization

Gold and silver mineralization in the Lucerne resource area is highly dependent on geologic attributes including but not limited to: multiple episodes of mineralization; numerous fault structures of varying orientations that acted as fluid conduits for precious metal transport; and amenable host rocks for deposition of economic concentrations of precious metals. The primary host rocks for the current Comstock resource areas are early Miocene age volcanic rocks, primarily andesitic to rhyolite volcanic flows, domes and intrusive rocks.

From 2007 through 2016, the Company drilled 997 RC and core holes in the Lucerne resource area, totaling 370,522 feet. The Lucerne geologic database now contains 1,850 holes totaling 473,224 feet, including 2004-2005, drilling by the Company and previous drilling by other mining companies.

Mineralization in the Lucerne resource area is located in the historic mine sites of the Lucerne open-cut, Justice, Keystone, Silver Hill, Hartford, Billie the Kid, and Woodville. The mentioned historic mines extracted precious metals from mining vein material from the northwest striking Silver City fault zone. Detailed studies by our geologic staff have identified within the Silver City fault zone four definitive sub-parallel northwest striking mineralized structures. The spacing between each of these structures is approximately 100 to 150 feet. Currently, definition and infill drilling on 50 to 100 foot centers has confirmed gold and silver mineralization over a strike distance of approximately one mile along the Silver City fault zone. Mineralization is open-ended to the north and south along strike and down-dip to the east, including the Chute Zone in the eastern portion of the Lucerne resource area.

Our geologists have also identified structurally complex zones developed within the Silver City fault zone that have enhanced precious metals grade of contiguous mineralization averaging 0.10 gold ounces per ton extending approximately 200 feet. The structural complexity is explained by a series of northeasterly striking structures that represent a separate, later mineralizing event intersecting with the northwesterly striking assembly of Silver City fault zone structures.

During 2014, 2015 and 2016, the mineralized material extracted from the Lucerne resource area and historical dumps progressively increased in silver content. In early 2014, the silver to gold ratio was approximately 10:1. As the open cut developed the northern Justice portion of the Lucerne and deepened down-dip along the Silver City fault zone, the silver to gold ratio increased. The 2014 weighted average of silver to gold ratio was 17.5:1. During 2015 the weighted average silver to gold ratio was 18.5:1. This compares to historic ratios of silver to gold of as high as 100:1 located in the northern Comstock District.

Future Exploration Potential

The Comstock Mining district is a well-known, historic mining district, with over 150 years of production-based history. From our first acquisition in the Comstock District, we have accumulated a vast collection of historic reports and maps on properties in the district. The data collection has been transformed into digital files with two-dimensional and three-dimensional presentation capabilities. Our exploration efforts in the past have been focused primarily upon the Lucerne and Dayton resource areas. We have conducted detailed geologic exploration and resource modeling on less than 10% of our approximate 9,272 -acre land position. Going forward the Company will continue ongoing exploration and development programs in the Lucerne and Dayton resource areas and expand the exploration to underground mineral targets. This will include but not be limited to further compilation and review of historic surface and sub-surface geology, geochemical and geophysical investigations and drilling.

Dayton Resource Area

The Company plans to conduct definition drilling and geotechnical core programs within the Dayton resource area. The Dayton southern expansion program includes exploration and definition drilling of targets identified by the conventional percussion drill program, magnetic, IP and resistivity geophysical surveys.

The Company plans to advance the Dayton resource area to full feasibility, with a production ready mine plan within the next two years. The volcanic host rocks and structural controls of the mineralization defined to date for the Dayton resource area are projected south into Spring Valley. Economic gold mineralization has been intercepted in several wide spaced drill holes conducted during prior Spring Valley drilling programs. Over the past several months, the technical staff has identified multiple drill targets within several specific locations that encompass the Dayton resource area and Spring Valley. The new targets are based on the Company's latest review of previous geophysical studies and current interpretation of the geology. The Company's long-term plan is to further develop the Lucerne resource area and the Dayton Spring Valley complex, while advancing plans for exploring the remaining historic mining areas, which include the Occidental group and Gold Hill group of exploration targets.

The geologic and engineering team completed underground mapping, sampling, and surveying in a number of historic mine tunnels on and near the Dayton resource area. Several historic mines operated in the Dayton area, leaving access to multiple structures from underground. Some historical adits have remained open or have been uncovered by the Company. Where accessible, the workings were inspected; geology mapped and mineralized material sampled. Once sampling was completed, the workings were surveyed to document the size of the mine workings, the location of the openings and location of the samples. The samples were then assayed at the Company’s in house metallurgical laboratory for gold and silver.

This underground sampling program has provided a wealth of assay information and provided critical information for furthering the geologic understanding of the Dayton. In some cases structures identified on the surface were traced underground and in other cases new structures were identified underground were surface expressions were absent or obscured. To facilitate one of the long lead items required to bring a project into production is baseline hydrologic data.

Dayton Hydrologic Study

A Reverse Circulation ("RC") drill program was designed to support the Water Pollution Control Permit application. The initial program would require fourteen drill sites to evaluate the hydrological regime of the mine location and an additional five drill holes for the proposed process facility.

The RC drilling would identify water levels and flow direction throughout the Dayton Project's hydrologic regime by testing multiple inner structurally bounded hydraulic cells. The measured static water levels, rate of flow and direction would be added to the mine model with respect to economic mineralization, proposed design mining depths and provide the initial mine water management requirements.

Several specific drill holes will provide multiple engineering attributes of the hydrologic and rock properties, including the potential of identifying additional economic resources. The completion of the RC drill holes will be used to position surgical core holes for geo-technical and metallurgical properties, acid/base accountability of waste rock and work indices of mineralized material.

A minimum of six RC drill holes will have three vibrating piezometers cemented down hole. One piezometer located within the top of the static water level. Another piezometer positioned mid-range within the water column and the third

piezometer located at the contact of the Miocene volcanic rocks and the Paleozoic basement rocks. The data collected from the placement of the piezometers will be used to better position monitor well locations.

Spring Valley

Spring Valley is located south of the Dayton resource area and south and east of State Route 341. Ground magnetic geophysical surveys identified a linear anomalous corridor, defined by a series of relative magnetic lows. Limited drilling in Spring Valley has intercepted altered volcanic host rocks and identified several mineralized zones. Selected drill hole intercepts are highlighted (see Figure 4 in the Exploration section of the Management Discussion and Analysis). The expanded exploration program for Spring Valley will include phased drilling programs that will continue southerly from SR341 to the historic Daney mine site (see Figure 5 in the Exploration section of the Management Discussion and Analysis). The targeted area has a total strike length of approximately 8,000 feet.

Occidental

The Occidental vein is a sub parallel vein system to the Comstock Lode and is considered by the Company to be an underexplored, potentially significant exploration target. The Occidental has also been historically referred to as the Brunswick Lode, with historic production records reporting 25,000 tons mined and processed from 1868 to 1894, at an average grade of approximately 0.75 opt gold equivalent. The underground workings were relatively shallow (350 ft) compared to some of the Comstock Lode mines that were developed to depths in excess of 3,000 feet. The Occidental vein system, spanning patented and unpatented claims, has a measured strike length of over 7,600 feet, on land controlled by the Company. Detailed geologic assessment combined with new technological advances in 3-D geophysical surveys will be reviewed to best define future drilling and development plans for this exploration target.

Gold Hill

The northern Comstock underground targets of the Gold Hill Group will be prioritized and exploration proposals will follow. Several locations in the Gold Hill Group have been selected for a focused underground development evaluation. The historic mining record of the area has multiple accounts of mining activity and production prematurely halted. The reasons for halting the historic mining activity have been documented by reports describing litigation, unfavorable rock conditions and economic mineralization crossing claim boundaries owned by other mining companies of the time. The Company now controls the contiguous lands of the Gold Hill group and has an opportunity to explore the mineral potential of this area more cost effectively by utilizing knowledge gained from the review of the historical records.

Item 3. Legal Proceedings

The Company’s mining and exploration activities are subject to various laws and regulations governing the protection of the environment. These laws and regulations are continually changing and are generally becoming more restrictive. The Company believes its operations are in compliance with applicable laws and regulations in all material respects. The Company has made, and expects to make in the future, expenditures to comply with such laws and regulations, but cannot predict the full amount of such future expenditures.

On January 31, 2014, the Comstock Residents Association (the “CRA”) and two of its members filed a civil action in the Third Judicial District Court of the State of Nevada in and for Lyon County (the “District Court”) against the Lyon County Board of Commissioners (the “Commissioners”) and the Company, asking the District Court to reverse the Commissioners’ decision to grant an application for master plan amendment and zone change submitted and approved by the Commissioners on January 2, 2014 (the “Application”).

Prior to the approval of the Application, the master plan designation and zoning precluded mining on certain property of the Company in the area of Silver City, Lyon County. In April 2015, the District Court ruled in favor the Company and the Commissioners. The written Order Denying Petition for Judicial Review was filed and mailed to all parties on June 15, 2015. On July 14, 2015, the CRA and one individual (together “Appellants”) filed a Notice of Appeal of the Court Order, appealing the decision to the Nevada Supreme Court. On December 9, 2015, Appellants filed their Opening Brief in the Nevada Supreme Court, generally repeating the arguments that were made at the District Court. On January 15, 2016, the Company and the Commissioners jointly filed an Answering Brief. Briefing in the Nevada Supreme Court was completed with the Appellants’

filing of a Reply Brief on March 3, 2016. An oral argument before a three-judge panel of the Nevada Supreme Court took place on September 14, 2016.

On December 2, 2016, the Nevada Supreme Court entered an order affirming all three of the District Court’s decisions associated with 1) the Commissioners’ discretion and authority for changing master plans and zoning, 2) their compliance with Nevada’s Open Meeting Law and 3) their compliance with Nevada statutory provisions. Specifically, the Supreme Court affirmed the District Court’s conclusions that Lyon County did not abuse its discretion and that it acted with substantial evidence in support of their decision, that the County did not violate Nevada’s Open Meeting Law and that the County did not violate statutory provisions regarding master plans.

The Supreme Court did reverse the District Court’s dismissal of CRA’s claim of a due process violation, concluding that this claim should not have been dismissed and that further proceedings are necessary in the District Court on this single claim. The Company and the Commissioners filed a motion for summary judgment with the District Court bases on the evidence in the record and the District Court held a hearing on December 11, 2017. The District Court concluded that the Supreme Court's reversal of CRA's due process claim required that CRA be afforded the opportunity to conduct discovery. Therefore, the District Court has allowed a limited time for CRA to conduct discovery on its due process claim and indicated that it would set the matter for a final hearing in mid-March 2018. To date, CRA has not conducted any discovery. The Company and the Lyon County District Attorney look forward to positive resolution of CRA's lone remaining claim.

Refer to the relevant portions of Note 17 of the Financial Section of this report for additional information on legal proceedings.

From time to time, we are involved in lawsuits, claims, investigations and proceedings that arise in the ordinary course of business. We maintain insurance to mitigate losses related to certain risks. There are no matters pending or threatened that we expect to have a material adverse impact on our business, results of operations, financial condition or cash flow.

Item 4. Mine Safety Disclosures

Under Section 1503(a) of the Dodd-Frank Wall Street and Consumer Protection Act, mine operations are required to include in their periodic reports filed with the SEC certain information concerning mine safety violations and other regulatory matters. The required information is included in Exhibit 95 to this report.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion provides information that we believe is relevant to an assessment and understanding of the consolidated results of operations and financial condition of the Company as of and for the year ended December 31, 2017 , as well as our future results. It should be read in conjunction with the consolidated financial statements and accompanying notes also included in this Form 10-K.

Overview

The Company and its subsidiaries now own or control approximately 9,272 acres of mining claims and parcels in the broader Comstock District and surrounding area. The acreage is comprised of approximately 2,347 acres of patented claims and surface parcels (private lands) and approximately 6,925 acres of unpatented mining claims (public lands), which the Bureau of Land Management (“BLM”) administers.

Because of the Comstock District’s historical significance, the geology is well known and has been extensively studied by the Company, our advisors and many independent researchers. We have expanded our understanding of the geology of the project area through vigorous surface mapping and drill hole logging. The volume of geologic data is immense, particularly in the Lucerne and Dayton resource areas. We have amassed a large library of historic data and detailed surface mapping of Comstock District properties and continue to obtain historic information from private and public sources. We use such data in conjunction with information obtained from our recent mining operations, to target geological prospective exploration areas and plan exploratory drilling programs, including expanded surface and underground drilling.

The Company continues evaluating and acquiring properties, expanding its footprint and evaluating all of our existing and prospective opportunities for further exploration, development and mining. The near-term goal of our business plan is to maximize intrinsic stockholder value realized, per share, by continuing to acquire and develop mineralized and potentially mineralized properties, exploring, developing and validating qualified resources (measured, indicated and inferred) and reserves (proven and probable) that enable the commercial development of our operations through extended, long-lived mine plans that are economically feasible and socially responsible, including mine plans for both the Lucerne and Dayton resource areas, with both surface and underground development opportunities.

Our Lucerne resource area is located in Storey County, Nevada, approximately three miles south of Virginia City and 30 miles southeast of Reno. The Lucerne resource area was host to the Company’s most-recent test mining operations from 2012 through 2015. The Company’s headquarters is on American Flat road, immediately north of the Lucerne resource area. The heap processing facility is in American Flat, approximately three quarters of a mile west of the Lucerne mine.

The Company achieved initial production and held its first pour of gold and silver on September 29, 2012. The Company ceased mining in 2015 and concluded processing in 2016, and accordingly did not have any gold or silver production or mining revenue during 2017. From 2012 through 2016 , the Company mined and processed approximately 2.6 million tons of mineralized material, and produced 59,515 ounces of gold and 735,252 ounces of silver.

Exploration & Development

District-wide

The Company's long-term plans contemplate the exploration and development of specific, identified geological target areas across the District, which the Company has grouped into the Lucerne and Dayton resource areas, and the Spring Valley group, Occidental group, and Gold Hill group of exploration targets. These exploration targets represent over 7 miles of mineralized strike length, with current and historical grades of gold and silver. Refer to Figure 3.

Figure 3 - General Overview of Priority Exploration Targets

Lucerne Resource Area

During 2016, the Company focused on exploration and development of certain properties within the Lucerne resource area primarily underground core drilling, underground drift (tunnel) development, and underground sampling into the Quartz Porphyry (“PQ”) and Succor geological targets. The Company encountered contiguous mineralized intercepts (10 to 40 feet) from bays 3 through 6 as it moved north of the Silver City/Succor structural intersection and within and bordering the PQ mass. The configuration of the longer and higher-grade intercepts occur along the hanging wall contact of the PQ intrusive mass within both the Alta Andesite and PQ host rocks. The intervals show continuity laterally and vertically along the structural contact.

Future drill programs were being developed with a phased approach to extend the PQ mineralization and scope the Succor and Woodville targets but the Company suspended those plans due to the higher than expected complexity of the underground development effort and the uncertainty about the total capital required for delivering a commercially viable mine plan. Ultimately, the Company decided to assess, evaluate and pursue partners willing and able to commit the additional mining expertise and capital resources required to explore and develop a commercially viable Lucerne-based mine plan.

On October 3, 2017, the Company entered into an Option Agreement (the “Option Agreement”) with Tonogold Resources, Inc. (“Tonogold”). Under the terms of the Option Agreement, Tonogold will have the right to participate in certain activities, including but not limited to, engineering, development, drilling and test-work, towards completing a technical and economic feasibility assessment on certain properties within the Lucerne Property and if all obligations and prerequisites are satisfied and subject to compliance with the Option Agreement, Comstock and Tonogold may effect a joint venture for the future development and mining of mineral resources on the Lucerne Property.

Under the terms of the Option Agreement, Tonogold can earn a 51% interest in the Company’s presently wholly-owned subsidiary, Comstock Mining LLC, which owns the Lucerne Property, by making capital expenditures on the Lucerne Property of $20 million by no later than 42 months following signing of the Option Agreement and payments of $2.2 million to the Company. In addition, if all conditions are met, Tonogold is also granted the option to purchase 51% of certain equipment and property located at the Company’s American Flat property for a purchase price of $25 million. Tonogold is also granted a right of first refusal if the Company elects, in its sole discretion, to sell certain mining properties.

The initial payment of $0.2 million was paid by Tonogold to the Company at the time that the Option Agreement went into effect. If Tonogold elects to proceed with the project, Tonogold would have to make another payment of $2 million within the six-month period following the date that the Option Agreement was signed. If Tonogold does not elect to extend the option beyond the initial six months, it will be required to make a further payment to the Company equal to $1 million less Tonogold’s actual expenditures on the Lucerne Property during such initial six-month period.

The Option Agreement calls for a Technical Committee composed of three Tonogold participants and two Comstock participants to oversee all of the engineering, development, drilling and test-work activities, and others, towards completing a technical and economic feasibility assessment. The Technical Committee reviewed the initial phase of the proposed due diligence program during November 2017.

Dayton Resource Area

The Company plans to advance the Dayton Project to full feasibility, with a production ready mine plan within the next two years. The plan includes expanding the current resource at the Dayton resource area and continuing southerly into Spring Valley with incremental expansion programs that include exploration and definition drilling of targets identified by the prior conventional percussion, RC and diamond core drill programs and magnetic, IP and resistivity geophysical surveys (see Figure 4).

In-house Dayton engineering and mine planning have resulted in profiling various economic pit shells with multiple cutoff grade scenarios. Multiple layout plans for the mine and corresponding processing facilities have been conceptually developed and located on lands 100% privately held by the Company, thus simplifying and shortening the critical permitting chain. A definition drill plan is in place and is permitted. An expanded drill plan is currently being designed and detailed plans will be submitted to the regulatory agencies for permitting.

In addition to infrastructure and drill planning, we performed due diligence assisted by SRK Consulting. The due diligence resulted in confirmation of the scoping level mine plans and agreement on the conceptual processing layout. The

Company plans to conduct definition drilling and geotechnical core programs within the Dayton resource area, as previously described, and advance this area to full feasibility, with a production-ready mine plan within the next two years

The volcanic host rocks and structural controls of the mineralization defined to date for the Dayton resource area are known to continue south into Spring Valley. Potentially economic gold mineralization has been intercepted in several wide spaced drill holes conducted during prior Spring Valley drilling programs. The technical staff has identified multiple drill targets within several specific locations that encompass the Dayton resource area and Spring Valley. The new targets are based on the Company's latest review of previous geophysical studies and current interpretation of the geology.

Figure 4 - Dayton -Spring Valley Magnetic Geophysics

Dayton - Spring Valley Group Targets

Spring Valley is located south of the Dayton resource area and south and east of State Route 341. Ground magnetic geophysical surveys identified a linear anomalous corridor, defined by a series of relative magnetic lows. Altered volcanic host rocks have been intercepted by limited drilling and identified several mineralized zones, the global Dayton resource foot print is outlined with reference to the technical report authored by Behre Dolbear in January 2013. The exploration of Spring Valley will include phased drilling programs that will continue southerly from SR341 to the historic Daney mine site (Figure 5), with a potential strike length of approximately 9,600 feet.

Figure 5 - Dayton and Spring Valley Group Targets

The technical staff reviewed historic geologic and geophysical studies and prior drill programs that focused upon the Dayton resource area and extensions south into Spring Valley. The few drill holes that were completed in Spring Valley intercepted altered Miocene volcanic rock known to host the economic mineralization of the Dayton resource. Specific drill holes that encountered highly mineralized zones are highlighted on Figure 4. Collectively, several specific locations were selected and are targeted for future drilling. The Dayton resource area has open ended economic mineralization requiring additional drill holes to delineate the geometry for mine planning. South of the Dayton resource area the limited drilling coupled with the geophysical interpretation indicates the targeted exploration model extends an additional 8,000 feet (length of geophysical magnetic survey) into Spring Valley.

Several historic mines operated in the Dayton resource area, leaving access to multiple structures from underground. Some historic adits have remained open or have been uncovered by the Company. The geologic and engineering team completed underground mapping, sampling, and surveying in a number of historic mine tunnels on and near the Dayton resource area. Where accessible, the workings were inspected; geology mapped and mineralized material sampled. Once sampling was completed, the workings were surveyed to document the size of the mine workings, the location of the openings and location of the samples. The samples were then assayed at the Company’s in house metallurgical laboratory for gold and silver.

This underground sampling program has provided a wealth of assay information and provided critical information for furthering the geologic understanding of the Dayton resource area. In some cases structures identified on the surface were traced underground and in other cases new structures were identified underground where surface expressions were absent or obscured.

Combining the underground study with the prior conventional percussion, RC and diamond core drill programs and magnetic, IP and resistivity geophysical surveys (Figure 4), new targets have been generated based on the Company's latest review of previous studies and current interpretation of the geology. The Dayton and Spring Valley southern expansion of exploration programs includes offset and definition drilling of these targets.

Ground magnetic geophysical surveys identified a linear anomalous corridor, defined by a series of relative magnetic lows. Altered volcanic host rocks have been intercepted by limited drilling and identified several mineralized zones. Selected drill hole intercepts are highlighted (see Figure 4). The mid-level magnetic lows define a zone (up to 500 feet wide) beginning at the Dayton resource and continuing southerly approximately 8,000 feet (length of geophysical magnetic survey) towards the Daney patent. The zone is further defined by the trace of interpreted north/south trending vein swarms depicted on Figure 6. In the Dayton resource area the increased density of the vein swarms with intersecting cross structures has been indicative to host the higher grades and larger volumes of economic mineralization. This scenario is part of the exploration model and has generated a multiple drill target environment.

The Spring Valley exploration program is designed to target areas that have similar magnetic signatures of known economic grade mineralization. The magnetic geophysical survey was further studied and a structural interpretation was developed that illustrated multiple cross cutting structures (colored green) that are oblique to the southerly projected north/south vein trend (colored red), refer to Figure 6. Though rare due to alluvial cover, the outcropping quartz veins and outcropping crosscutting structures had definitive diagnostic magnetic signatures. The interpretation of the structures and veins were derived by connecting these specific magnetic attributes as identified on each 25-meter spaced survey line. Similar structures have been identified in the Dayton resource area and were found to be important components for the development of economic grades of mineralization. Geologic mapping and sample analysis conducted on the surface and in accessible underground workings have identified the north/south and the crosscutting structures to carry gold and silver values with varying silver to gold ratios. Comparisons of selected sample geochemistry, the north/south veins commonly have a relatively higher silver to gold ratio.

Figure 6 - Dayton and Spring Valley Magnetic Geophysics with Interpreted Veins and Structures

The Company also recently completed metallurgical column tests on mineralized material from the Dayton resource area that contribute to the advancement of a full feasibility assessment for the mine, updating prior metallurgical test work and the technical resource report published in January 2013. During the second quarter of 2017, the Company conducted column tests of both cyanide and non-cyanide solutions. They established four, full metallurgical column tests, two cyanide and two non-cyanide, running parallel, that supports and advances the feasibility study for establishing proven and probable reserves at the Dayton resource area. The samples were crushed, agglomerated and loaded into four ten-foot columns for leach simulation. These simulations were conducted on-site, in the Company’s metallurgical labs, and are coordinated through Cycladex Inc., (“Cycladex”) a strategic investee, and funded by U.S. National Science Foundation grants.

The Cyanide columns yielded between 82-85% gold in just 25 days. The Company has already designed and established new column tests for the primary purpose of assessing the specific consumption of the new materials and material cost for processing. This is important for assessing ultimate economic feasibility of these solutions.

These simulations will also be conducted on-site, in the Company’s metallurgical labs, and are still funded by U.S. National Science Foundation research grants. This updated metallurgical testing complement extensive metallurgical testing for the Dayton resource area that were previously published in 2011.

Production

The Company operated a heap leach based, gold and silver production system, including a zinc-precipitate based Merrill-Crowe processing plant. The Company, under the existing water pollution control permit with the State of Nevada, has the crushing and processing capacity to operate at a rate of up to 4.0 million tons of material crushed and stacked, per annum. The Merrill-Crowe system facilitated that capacity with an operating fluid processing rate of over 1,000 gallons per minute.

The Company completed mining operations in 2015. The leaching process continued through December 2016, when the Company determined that continued leaching was no longer economic. The Company mined and processed approximately 2.6 million tons of mineralized material from 2012 through 2016, producing 59,515 ounces of gold and 735,252 ounces of silver. The Company estimated recovery reached approximately 88.5% of the contained gold and 59.5% of the contained silver from the heap leach.

Operating Costs

During fiscal year 2017 , cost applicable to mining revenue was $3.4 million , as compared to fiscal year 2016 of $5.7 million , and $4.5 million net of $1.2 million of silver by-product credits. This 40% reduction of cost applicable to mining revenue is primarily a result of the cessation of mining in December, 2016, with significantly lower labor and processing costs as the Company’s fully transitioned from surface mining activities back to exploration. Costs applicable to mining revenue in 2016, includes processing labor, processing maintenance, processing reagents and assaying costs, among others. Cost applicable to mining revenue includes $3.4 million and $2.6 million of depreciation for 2017 and 2016 , respectively.

During the past 18 months and including the year ended December 31, 2017 , the Company has also focused on reducing non-mining costs. The Company has aggressively implemented organizational changes consistent with our transition from mining the Lucerne surface mine to growing our resource portfolio and related exploration and development activities toward production-ready mining projects. Accordingly, general and administrative costs and other non-mining costs, including mine claims and land costs, other real estate operating costs and environmental costs, have already declined $5.2 million as compared to 2016 . In addition, the Company eliminated royalties on both the Dayton and Lucerne resource areas and simplified the capital structure, saving an additional $5.5 million over 2015, in dividends and payments associated with the former preferred share structure. The Company incurred approximately $0.3 million in severance costs during the year ended December 2016 and none for year ended December 31, 2017 , in mining, mine support and general and administrative expenses, associated with organizational cost reductions.

Outlook

Our goal is to deliver up to $500 million of accretive share value (over $10 per share) by 2020, by acquiring, joint venturing, exploring and developing resources and reserves capable of sustaining production of more than 100,000 gold-equivalent ounces per annum. Our past efforts, especially during the past 18 months, have positioned us for this success. These production targets include both the Lucerne and Dayton Mine plans, with both surface and underground development opportunities.

Total operating expenses (excluding depreciation, amortization, and depletion expense) are expected to be $3.6 million in 2018. The Tonogold agreement, if the second phase is exercised, has the potential for reducing these annual operating expenses (excluding depreciation, amortization, and depletion expense) of $3.6 million, in 2018, by an additional $1.25 million. Interest expense is expected to be approximately $1.2 million for 2018. The Company expects to continue operating with approximately 12 employees, including expert land, permitting, geology and engineering professionals.

The Company plans to sell non-mining related lands, buildings and water rights, for expected net cash proceeds of approximately $14 million during the next twelve months resulting in a net gain of approximately $8 million. These proceeds will first be used to eliminate debt obligations due under the Debenture (including principal, accrued interest, and make whole amounts), and to fund certain exploration activities in the Dayton resource area, all while strengthening the financial position of the Company.

The Company has also commenced and plans on continuing metallurgical testing on Dayton mineralized materials and our existing leach pad materials, using both cyanide and non-cyanide alternative solutions to experiment on achieving the highest, most cost efficient processing for the Dayton and our other feasibility assessments. The Company has developed grade shells with higher average grades and believes the Dayton to have economically feasible potential and plans on developing those mine plans toward full feasibility during late 2018, with production plans following those efforts within the next two years.

The Company will report the results of the Lucerne exploration and development programs, in conjunction with Tonogold, and independently for Dayton exploration and development programs, as they become available.

Equity Raises

During the year ended December 31, 2017 , the Company issued 9,464,764 shares of common stock through the Company’s at-the-market and equity purchase offering programs. Gross proceeds from the issuance of shares totaled approximately $7.3 million at an average price per share of $0.78 .

Mining revenue decreased by $4.9 million in 2017 , as compared to the year ended 2016 . The Company ceased processing material from its leach pad in December 2016, resulting in no mining revenues for year ended 2017 .

Real estate revenue was $0.1 million for the year ended December 31, 2017 , consistent with the year ended December 31, 2016. Effective April 1, 2015, the Company entered into an agreement to lease the Gold Hill Hotel operations. The Company retains ownership to the land and the Gold Hill Hotel properties while leasing the facilities and business to independent operators. Real estate revenue decreased $ 0.1 million from 2016 to 2015 . This decrease is primarily from higher direct hospitality revenue in 2015, in addition to leasing revenue from the independent operators, whereas 2016 and 2017 consistently, reflects just the leasing revenue.

Real estate operating costs decreased $0.1 million for the year ended December 31, 2017 , as compared to the year ended December 31, 2016 . This decrease primarily resulted from costs savings related to the leasing of the facilities and business to independent operators. Real estate operating costs decreased $0.2 million for the year ended 2016 compared to the same period in 2015 . This decrease is primarily from leasing the hotel to independent operators.

Costs applicable to mining revenue decreased by $ 1.1 million for the year ended December 31, 2017 , as compared to 2016 . The 25% reduction resulted from lower processing costs and the reduction of substantially all the mining and processing staff consistent with ceasing processing operations in December 2016. Costs for the year ending in 2017, consisted solely of depreciation expense on temporarily idled mining equipment, processing facilities, and heap leach pads. Costs applicable to mining revenue decreased by $6.1 million for the year ended December 31, 2016 , as compared to 2015 . The decrease resulted from the completion of the Company’s first phase of mining and the transition toward the next phase of exploration and mine development resulting in lower mining and processing costs from the reduction of mining and processing staff.

Exploration and mine development decreased by $3.4 million in 2017 , as compared to 2016 . The decrease represents substantially all of remaining underground exploration and development costs incurred during the year ending in 2016, including the completion of the crosscut drift from the main PQ drift to the Succor vein system in Lucerne’s underground development, including approximately $1.8 million of depreciation expense associated with equipment used in that development, that did not recur in 2017. Exploration and mine development costs decreased by $2.4 million in 2016 , as compared to 2015 . The decrease is also the result of the majority of the exploration costs related to underground development activities and the completion of the Lucerne underground drifts being incurred in 215, with the remaining efforts occurring in the first two month of 2016.

Mine claim and costs decreased by $0.1 million for the year ended 2017 , as compared to 2016 , primarily due to lower lease payments. Mine claim costs consist of annual claim filing fees, lease payments and annual payments related to the Northern Comstock joint venture. Mine claim and costs decreased by $0.2 million for the year ended 2016, as compared to

2015. The operating agreement of Northern Comstock LLC was amended in the third quarter of 2015, resulting in significantly lower annual costs, of approximately $0.2 million per annum, in 2016 compared to 2015.

Environmental and reclamation costs decreased by $ 0.5 million in 2017 , as compared to year ended 2016 . The decrease is the result of lower environmental labor and lower asset retirement obligation depreciation. Environmental and reclamation expenses decreased $ 0.7 million for the year ended 2016 , as compared to the year ended 2015 . The decrease is the result of lower environmental consulting and lower third party expenses associated with engineering services and mine planning offset by an increase in costs of contract service fees to commence the underground drift and drilling, associated with the first underground exploration phase of a PQ target.

Land and road development cost were $0.1 million in 2016 and $2.9 million in 2015 due to the road realignment project that was successfully completed in 2016.

General and administrative expenses decreased by $0.9 million for the year ended 2017 , as compared to the year ended 2016 . The decrease is a result of lower payroll and administrative cost reductions, in line with targeted cost reductions.

General and administrative expenses decreased by $3.2 million for the year ended 2016 , as compared to the year ended 2015 . This decrease is primarily due to lower payroll costs of approximately $1.3 million, reduced fees, insurance and marketing of $0.6 million, reduced taxes of $0.5 million, lower legal and consulting fees of approximately $0.3 million, among other reductions, all in line with the cost reduction programs.

Interest Expense increased by $1.0 million for the year ended 2017, as compared to year ended 2016. The increase is a result of the refinancing of substantially all debt on January 13, 2017 with a Senior Secured Debenture which has a higher effective interest rate than the debt agreements refinanced. Interest expense decreased by $0.5 million in 2016 as compared to 2015 . The decrease is the result of the reduction or payoff of various financing arrangements and loans.

Other Expense decreased by $2.0 million for the year ended 2017, as compared to year ended 2016. The loss in 2016 was caused by fair value adjustments recorded on make-whole provisions from common shares issued in 2016 as payment for certain debt obligations. The debt obligations were paid in full in January 2017. The increase of $5.2 million in 2016, as compared to 2015, primarily resulted from a reduction in a loss contingency of approximately $3.2 million that was included in other income in the consolidated statements of operation in 2015, and did not recur in 2016, and from other costs associated with property and equipment purchases.

Net loss was $10.6 million and $13.0 million for the years ended December 31, 2017 , and 2016 , respectively.

The decrease of $2.4 million in 2017 from 2016 was primarily the result of a $4.9 million decrease in revenue, offset by a $7.5 million reduction of all other operating expenses, including lower costs in all other categories. The increase of $2.5 million in 2016, from 2015, was primarily the result of a $13.3 million decrease in revenue as the Company began winding down the Lucerne mining activities, offset by a $10.9 million reduction of all other operating expenses, including $6.1 million in cost applicable to mining, $2.8 million for road development and net lower costs in all other categories.

Liquidity and Capital Resources

Total current assets are $7.7 million at December 31, 2017 . Cash and cash equivalents on hand at December 31, 2017 totaled $2.1 million . The Company’s current capital resources include these cash and cash equivalents and other working capital resources, certain planned, non-mining asset sales with expected net proceeds of over $14 million and other existing financing arrangements.

Effective June 28, 2016, the Company entered into a sales agreement with IAA with respect to an ATM agreement pursuant to which the Company may offer and sell, from time to time at its sole discretion, shares of its common stock, having an aggregate offering price of up to $5 million. $4.2 million of shares were issued in 2017 and $0.5 million were issued in 2016. The Company had $0.3 million available to use under the sales agreement as of December 31, 2017. Effective April 2017, the Company also entered into a Purchase agreement with Leviston for the purchase of up to $7.25 million of shares of the Company's common stock from time to time, at the Company's option. The Company is not obligated to make any sales of shares under either the ATM or Purchase agreement, and if it elects to make any sales, the Company can set a minimum sales price for the shares. As of December 31, the Company has issued shares to Leviston and received cash proceeds of $3.15 million. The Company had $4.1 million available to be used under the Purchase Agreement as of December 31, 2017.

While the Company has been successful in the past in obtaining the necessary capital to support its operations, including registered equity financings from its existing shelf registration, borrowings, or other means, there is no assurance that the Company will be able to obtain additional equity or other financing, if needed. The Company believes it will have sufficient funds to sustain operations during the next twelve months as a result of the sources of funding described above.

Net cash used in operating activities for the year ended December 31, 2017 was $6.5 million as compared to net cash used of $2.6 million for the year ended 2016 . The Company's use of cash in 2017 , was primarily related to general and administrative, exploration, mine claim cost and environmental expenditures. The Company’s use of cash in 2016 was primarily related to underground drift and exploration expenditures, including the PQ and Succor targets and general and administrative expenses, somewhat offset by 2016 revenues. Our use of cash in 2015 , included $2.9 million for the SR-342 road realignment project, $3.3 million costs related to underground drift and exploration and $2.0 million for a reduction of accrued liabilities, offset by positive cash flow from revenues in excess of costs associated with mining revenue due to lower operating costs associated with lower labor, blasting, fuel and lower equipment costs.

Net cash provided by investing activities for the year ended December 31, 2017 , was $1.0 million , primarily from land, water rights, and equipment sales of approximately $1.1 million, offset by purchase of land, properties and equipment of approximately $0.1 million. Cash provided by investing activities for the year ended 2016 , was $2.6 million , primarily from equipment sales of approximately $3.3 million, offset by purchases of land and properties of approximately $0.8 million.

Net cash provided by financing activities for fiscal year 2017 was $7.4 million , substantially all resulting from net proceeds of $7.1 million from the sale of common stock, $0.2 million option fee received from Tonogold Resources, Inc., and $9.4 million of proceeds from issuance of a Senior Secured Debenture, offset by pay-down of long-term debt obligations of approximately $9.2 million. Net cash used in financing activities for fiscal year 2016 , was $1.4 million , comprised of net proceeds of $4.0 million from sale of securities, $0.6 million proceeds from an amended agreement with Auramet, and $0.3 million from proceeds from a short-term note, offset by the pay-down of long term debt obligations of approximately $6.3 million.

The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America which contemplates continuation of the Company as a going concern.

The Company commenced production with the Lucerne Mine in 2012, and ramped up to approximately

20,000 gold-equivalent-ounces of annual production. The Company completed leaching from its existing leach pads in December 2016 and is currently planning the exploration and development of its next two mines, first with its second surface mine in the Dayton resource area and then further developing, in collaboration through an agreement with a potential joint venture partner, the second phase of development and production from the Lucerne Mine.

The Company has recurring net losses from operations and an accumulated deficit of $222.6 million as of December 31, 2017 . For the year ended December 31, 2017 , the Company incurred a net loss of $10.6 million and used $6.5 million of cash in operations. As of December 31, 2017 , the Company had cash and cash equivalents of $2.1 million , current assets of $7.7 million and current liabilities of $1.1 million , resulting in net working capital of $6.6 million .

The Company’s current capital resources include cash and cash equivalents and other net working capital resources, along with a loan commitment agreement with $7.0 million in unused capacity, after consideration of fees due at the time of borrowing. The Company also has an at-the-market ("ATM") equity offering program with International Assets Advisory LLC ("IAA"), and an equity purchase agreement (the "Purchase Agreement") with Leviston Resources, LLC ("Leviston"), with aggregate unused capacity of $4.4 million. These capital resources are in addition to certain planned non-mining asset sales.

While the Company has been successful in the past in obtaining the necessary capital to support its operations, including registered equity financings from its existing shelf registration statement, borrowings, or other means, there is no assurance that the Company will be able to obtain additional equity capital or other financing, if needed. However, the Company believes it will have sufficient funds to sustain its operations during the next 12 months from the date the financial statements were issued as a result of the sources of funding detailed above.

Future operating expenditures above management’s expectations, including exploration and mine development expenditures in excess of amounts to be raised from the issuance of equity under the ATM Agreement and Purchase Agreement, declines in the market value of properties held for sale, or declines in the share price of the Company's common stock, would adversely affect the Company’s results of operations, financial condition and cash flows. If the Company was unable to obtain any necessary additional funds, this could have an immediate material adverse effect on liquidity and could raise substantial doubt about the

Company’s ability to continue as a going concern. In such case, the Company could be required to limit or discontinue certain business plans, activities or operations, reduce or delay certain capital expenditures or sell certain assets or businesses. There can be no assurance that the Company would be able to take any such actions on favorable terms, in a timely manner or at all.

⁽²⁾	The Company leases certain properties under operating leases expiring at various dates through 2027. See Note 17 to the Consolidated Financial Statements. Amounts include minimum rental and minimum advance royalty payments.

⁽³⁾

We are required to mitigate long-term environment impacts by stabilizing, contouring, resloping, and revegetating various portions of a site after mining and mineral processing operations are completed. These reclamation efforts are conducted in accordance with plans reviewed and approved by the appropriate regulatory agencies. The Nevada State Environmental Commission and Division of Environmental Protection and other agencies have approved our most recent reclamation plans, as revised, of approximately $6.8 million. In addition, the Company placed a $0.6 million reclamation surety bond through the Lexon Surety Group (“Lexon”) and a $1.5 million with Storey County related to reclamation as of December 31, 2017 . See Note 7 to the Consolidated Financial Statements.

Critical Accounting Estimates

The SEC has requested that all registrants address their most critical accounting policies. The SEC has indicated that a “critical accounting policy” is one which is both important to the representation of the registrant’s financial condition and results and requires management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. We base our estimates on past experience and on various other assumptions our management believes to be reasonable under the circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results will differ, and may differ materially from these estimates under different assumptions or conditions. Additionally, changes in accounting estimates could occur in the future from period to period. Our management has discussed the development and selection of our most critical financial estimates with the audit committee of our Board of Directors. The following paragraphs identify our most critical accounting policies:

Impairment of Mineral Rights and Properties, Plant and Equipment

The Company assesses its mineral rights and properties, plant and equipment for possible impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Such indicators include changes in the Company’s business plans, changes in precious metal prices and significant downward revisions of estimated mineralization quantities. If the carrying value of an asset exceeds the future undiscounted cash flows expected from the asset, an impairment charge is recorded for the excess of carrying value of the asset over its estimated fair value.

Determination as to whether and how much an asset is impaired involves management estimates on highly uncertain matters such as future commodity prices, the effects of inflation and technology improvements on operating expenses, and the outlook for global or regional demand conditions for gold and silver. However, the impairment reviews and calculations are based on assumptions that are consistent with the Company’s business plans and long-term investment decisions.

Reclamation and Remediation Obligations

Reclamation costs are allocated to expense over the life of the related assets and are periodically adjusted to reflect changes in the estimated present value resulting from the passage of time and revisions to the estimates of either the timing or amount of the reclamation and remediation costs. Reclamation obligations are based on when the spending for an existing environmental disturbance will occur. We review, on at least an annual basis, the reclamation obligation at each mine site in accordance with guidance for accounting for asset retirement obligations.

Reclamation obligations for inactive mines are accrued based on management’s best estimate of the costs expected to be incurred at a site. Such cost estimates include, where applicable, ongoing care, maintenance and monitoring costs. Changes in estimates at inactive mines are reflected in earnings in the period an estimate is revised.

Accounting for reclamation and remediation obligations requires management to make estimates unique to each mining operation of the future costs we will incur to complete the reclamation and remediation work required to comply with existing laws and regulations. Actual costs incurred in future periods could differ from amounts estimated. Additionally, future changes to environmental laws and regulations could increase the extent of reclamation and remediation work required. Any such increases in future costs could materially impact the amounts charged to earnings for reclamation and remediation.

Income Taxes

Our income tax expense and deferred tax assets and liabilities reflect management’s best assessment of estimated future taxes to be paid. Deferred income taxes arise from temporary differences between the tax and financial statement recognition of revenue and expense. In evaluating our ability to recover our deferred tax assets, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial operations. In projecting future taxable income, we develop assumptions including the amount of future state, federal and foreign pretax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates that we are using to manage the underlying businesses. Valuation allowances are recorded as reserves against net deferred tax assets by the Company when it is determined that net deferred tax assets are not likely to be realized in the foreseeable future.

The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations. Income tax positions must meet a more-likely-than-not recognition threshold to be recognized.

Item 7a. Quantitative and Qualitative Disclosures about Market Risk

Metal Price – Changes in the market price of gold may significantly affect our profitability and cash flow. Gold prices fluctuate widely due to factors such as: demand, global mine production levels, investor sentiment, central bank reserves, and the value of the U.S. dollar.

Interest Rate Risk – Our exposure to market risk is confined to our cash and cash equivalents, all of which have maturities of less than three months and bear and pay interest in U.S. dollars. Since we invest in highly liquid, relatively low yield investments, we do not believe interest rate changes would have a material impact on us.

Our risk associated with fluctuating interest expense is limited to other short-term obligations we may incur in our normal operations. The interest rates on our existing long-term debt borrowings are fixed and as a result, interest due on borrowings are not impacted by changes in market-based interest rates.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Comstock Mining Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Comstock Mining Inc. and subsidiaries (the "Company") as of December 31, 2017 and 2016, and the related consolidated statements of operations, changes in stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2017, and the related notes and the schedule listed in the Index at Item 15 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

COMSTOCK MINING INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2017 , 2016 AND 2015

1. Nature of Business

Comstock Mining Inc. is a Nevada-based gold and silver exploration, development and production-focused mining company with extensive, contiguous property in the historic Comstock and Silver City mining districts (collectively, the “Comstock District”). The Comstock District is located within the western portion of the Basin and Range Province of Nevada, between Reno and Carson City, Nevada. Our Lucerne resource area is located in Storey County, Nevada, approximately three miles south of Virginia City, Nevada and 30 miles southeast of Reno, Nevada. Our Dayton resource area is located in Lyon County, Nevada, approximately six miles south of Virginia City, Nevada. The Company also owns extensive real estate holdings, including but not limited to the Gold Hill Hotel located in Gold Hill, Nevada, just south of Virginia City, the Daney Ranch, located just south of Silver City, and 98 acres of land and 257 acre-feet of senior-priority water rights in Silver Springs, Nevada. As used in the notes to the consolidated financial statements, we refer to Comstock Mining Inc., and its wholly owned subsidiaries as “we,” “us,” “our,” “our Company,” or “the Company.”

We continue expanding our property footprint and creating opportunities for exploration, development and mining. The Company now owns or controls approximately 9,272 acres of mining claims and parcels in the Comstock and Silver City Districts. The acreage is comprised of approximately 2,347 acres of patented claims (private lands) and surface parcels (private lands) and approximately 6,925 acres of unpatented mining claims, which the Bureau of Land Management, (“BLM”) administers.

2. Summary of Significant Accounting Policies

Principles of Consolidation - The consolidated financial statements include the accounts of Comstock Mining Inc., and its wholly owned subsidiaries: Comstock Mining LLC, Comstock Real Estate Inc. and Comstock Industrial LLC. Inter-company transactions and balances have been eliminated.

Basis of Presentation - The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America which contemplates continuation of the Company as a going concern.

The Company commenced production with the Lucerne Mine in 2012, and ramped up to approximately

The Company’s current capital resources include cash and cash equivalents and other net working capital resources, along with a loan commitment agreement with $7.0 million in unused capacity, after consideration of fees due at the time of borrowing. The Company also has an at-the-market ("ATM") equity offering program with International Assets Advisory LLC ("IAA"), and an equity purchase agreement (the "Purchase Agreement") with Leviston Resources, LLC ("Leviston"), with aggregate unused capacity of $4.4 million . These capital resources are in addition to certain planned non-mining asset sales.

While the Company has been successful in the past in obtaining the necessary capital to support its operations, including registered equity financings from its existing shelf registration statement, borrowings, or other means, there is no assurance that the Company will be able to obtain additional equity capital or other financing, if needed. However, the Company believes it will have sufficient funds to sustain its operations during the next 12 months from the date the financial statements were issued as a result of the sources of funding detailed above.

F-8

the Company’s results of operations, financial condition and cash flows. If the Company was unable to obtain any necessary additional funds, this could have an immediate material adverse effect on liquidity and could raise substantial doubt about the Company’s ability to continue as a going concern. In such case, the Company could be required to limit or discontinue certain business plans, activities or operations, reduce or delay certain capital expenditures or sell certain assets or businesses. There can be no assurance that the Company would be able to take any such actions on favorable terms, in a timely manner or at all.

Fair Value Measurements - The fair value of a financial instrument is the amount that could be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value should be calculated based on assumptions that market participants would use in pricing the asset or liability, not on assumptions specific to the entity. In addition, the fair value of liabilities should include consideration of non-performance risk, including the party’s own credit risk.

Fair value measurements do not include transaction costs. A fair value hierarchy is used to prioritize the quality and reliability of the information used to determine fair values. Categorization within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is defined into the following three categories:

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that are not corroborated by market data.

Long-Lived Assets - We review the carrying amount of our long-lived assets for impairment whenever there are negative indicators of impairment. An asset is considered impaired when estimated future cash flows are less than the carrying amount of the asset. In the event the carrying amount of such asset is not considered recoverable, the asset is adjusted to its fair value. Fair value is generally determined based on discounted future cash flows.

Mineral Rights and Properties - We defer acquisition costs until we determine the viability of the property. Since we do not have proven and probable reserves as defined by Securities and Exchange Commission (“SEC”) Industry Guide 7, exploration expenditures are expensed as incurred. We expense care and maintenance costs as incurred.

We review the carrying value of our mineral rights and properties for impairment whenever there are negative indicators of impairment. Our estimate of the gold price, mineralized materials, operating capital, and reclamation costs are subject to risks and uncertainties affecting the recoverability of our investment in the mineral claims and properties. Although we have made our best, most current estimate of these factors, it is possible that near term changes could adversely affect estimated net cash flows from our mineral claims and properties and possibly require future asset impairment write-downs.

Where estimates of future net operating cash flows are not available and where other conditions suggest impairment, we assess recoverability of carrying value from other means, including net cash flows generated by the sale of the asset. We use the units-of-production method to deplete the mineral rights and properties.

Properties, Plant and Equipment - We record properties, plant and equipment at historical cost. We provide depreciation and amortization in amounts sufficient to match the cost of depreciable assets to operations over their estimated service lives or productive value. We capitalize expenditures for improvements that significantly extend the useful life of an asset. We charge expenditures for maintenance and repairs to operations when incurred. Depreciation is computed using the straight-line method over estimated useful lives as follows:



Building	7 to 15 years
Vehicles and equipment	3 to 7 years
Processing and laboratory	5 to 15 years
Furniture and fixtures	2 to 3 years

Reclamation Liabilities and Asset Retirement Obligations - Minimum standards for site reclamation and closure have been established for us by various government agencies. Asset retirement obligations are recognized when incurred and recorded as liabilities at fair value. The liability is accreted over time through periodic charges to earnings. In addition, the asset retirement cost is capitalized and amortized over the life of the related asset. Reclamation costs are periodically adjusted to reflect changes in the estimated present value resulting from the passage of time and revisions to the estimates of either the timing or amount of the reclamation and abandonment costs. The Company reviews, on an annual basis, unless otherwise deemed necessary, the asset retirement obligation at each mine site.

F-9

Revenue Recognition - Revenue is recognized from sales when persuasive evidence of an arrangement exists, the price is determinable, the product has been delivered, the title has been transferred to the customer and collection of the sales price is reasonably assured. Gold revenue is recorded at an agreed upon spot price and gold ounce measurement resulting in revenue and a receivable at the time of sale. Gold revenue is recorded net of refining charges and discounts. Sales of by-products (such as silver) are credited to costs applicable to mining revenue. Real estate revenue is recognized as services are provided to customers.

Substantially all mining revenues recorded relate to a single customer. As gold can be sold through numerous gold market traders worldwide, the Company is not economically dependent on a limited number of customers for the sale of its product.

Stock Issued For Goods and Services - Common shares issued for goods and services are valued based upon the fair market value of our common stock or the goods and services received, whichever is the most reliably measurable on the date of issue.

Stock-Based Compensation - For stock-based transactions, compensation expense is recognized over the requisite service period, which is generally the vesting period, based on the estimated fair value on the grant date of the award.

Loss per Common Share - Basic net loss per common share is computed by dividing net loss, less the preferred stock dividends, by the weighted average number of common shares outstanding. Dilutive loss per share includes any additional dilution from common stock equivalents, such as stock options and warrants, and convertible instruments, if the impact is not antidilutive. Since the Company incurred net losses for the periods presented, all equity-linked instruments are considered anti-dilutive.

Comprehensive Loss - There were no components of comprehensive loss other than net loss for the years ended December 31, 2017 , 2016 and 2015 .

Income Taxes - The Company’s income tax expense and deferred tax assets and liabilities reflect management’s best assessment of estimated future taxes to be paid. Significant judgments and estimates are required in determining the consolidated income tax expense.

Deferred income taxes arise from temporary differences between the tax and financial statement recognition of revenue and expense. In evaluating the Company’s ability to recover its deferred tax assets, management considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial operations. In projecting future taxable income, the Company develops assumptions including the amount of future state and federal pretax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income, and are consistent with the plans and estimates that the Company is using to manage the underlying businesses. The Company provides a valuation allowance for deferred tax assets for which the Company does not consider realization of such deferred tax assets to be more likely than not.

Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. Other than the impacts of the new federal tax reform legislation disclosed in Note 15, management is not aware of any such changes that would have a material effect on the Company’s results of operations, cash flows or financial position.

Use of Estimates - In preparing financial statements in conformity with generally accepted accounting principles, we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenditures during the reported periods. Actual results could differ materially from those estimates. Estimates may include those pertaining to the estimated useful lives and valuation of properties, plant and equipment, mineral rights and properties, deferred tax assets, reclamation liabilities, and contingent liabilities.

Reverse Stock Split - Effective November 9, 2017, the Company completed a 1-for-5 reverse stock split of its authorized and outstanding common stock, as approved by its Board of Directors. All common shares and per share amounts set forth herein give effect to this reverse stock split.

Recently Issued Accounting Pronouncements – In January 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2017-01 - Business Combinations (Topic 805), which clarifies the definition of a business. For accounting and financial reporting purposes, businesses are generally comprised of three elements; inputs, processes, and outputs. Integrated sets of assets and activities capable of providing these three elements may not always be considered a business, and the lack of one of the three elements does not always disqualify the set from being a business. The

F-10

issuance of ASU No. 2017-01 provides a clarifying screen to determine when a set of assets and activities is not a business. Primarily, the screen requires that when substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets, the set is not a business. The amendments contained in ASU No. 2017-01 are effective for annual periods beginning after December 15, 2017 and may be early adopted for certain transactions that have occurred before the effective date, but only when the underlying transaction has not been reported in the financial statements that have been issued or made available for issuance. The Company does not believe the implementation of ASU 2017-01 will have a material effect on its financial position, operational results, or cash flows.

In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”), which amends ASC 230, Statement of Cash Flows, and the FASB’s standards for reporting cash flows in general-purpose financial statements. The amendments address the diversity in practice related to the classification of certain cash receipts and payments including debt prepayment or debt extinguishment costs. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, and early adoption is permitted. The Company is currently evaluating the impact of the adoption of this guidance on the Company’s consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Topic 842 affects any entity that enters into a lease, with some specified scope exceptions. For public business entities, the amendments in this update are effective for financial statements issued for annual periods beginning after December 15, 2018, and interim periods within those annual periods. Early application is permitted for all entities. The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements, which will require right of use assets and lease liabilities be recorded in the consolidated balance sheet for operating leases.

In May 2014, the FASB issued ASU 2014-09 (Topic 606) that introduces a new five-step revenue recognition model that an entity should use to recognize revenue when depicting the transfer of promised goods or services to customers in an amount that reflects the consideration that the entity expects to be entitled in exchange for those goods or services. This ASU also requires disclosures sufficient to enable users to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers, including qualitative and quantitative disclosures about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. On July 9, 2015, the FASB deferred the effective date to fiscal years beginning after December 15, 2017, and for interim periods within those fiscal years.

We will use the modified retrospective method to adopt the provisions of this standard effective January 1, 2018, which requires us to apply the new revenue standard to (i) all new revenue contracts entered into after January 1, 2018 and (ii) all existing revenue contracts as of January 1, 2018 through a cumulative adjustment to retained earnings. In accordance with this approach, our consolidated revenues for the periods prior to January 1, 2018 will not be revised. The Company will not record a cumulative effect adjustment to its beginning retained earnings as a result of adoption of Topic 606 as there are no revenue contracts within the scope of Topic 606 as of January 1, 2018.

Assets Held For Sale

The Company committed to a plan to sell certain land and buildings. As of December 31, 2017 , the Company had assets with a net book value of $5.4 million that met the criteria to be classified as assets held for sale. Those criteria specify that the asset must be available for immediate sale in its present condition (subject only to terms that are usual and customary for sales of such assets), the sale of the asset must be probable, and its transfer expected to qualify for recognition as a completed sale generally within one year. Proceeds from the sale of these assets are required to be used to satisfy obligations due under the terms of the debenture with GF Comstock 2 LP as described in Note 9.

6. Reclamation Bond Deposit

The Nevada Revised Statutes and Regulations require a surety bond to be posted for mining projects so that after the completion of such mining projects the sites are left safe, stable and capable of productive post-mining uses. The bond is intended to cover the estimated costs required to safely reclaim the natural environment to the regulatory standards established by the State of Nevada’s Division of Environmental Protection. Accordingly, the Company has a $7.1 million reclamation

F-12

surety bond through the Lexon Surety Group (“Lexon”) with the State of Nevada’s Bureau of Mining Regulation and Reclamation as of December 31, 2017 . In addition, the Company has a $0.5 million surety bond with Storey County related to mine reclamation as of December 31, 2017 . As part of the surety agreement, the Company agreed to pay a 2.0% annual bonding fee. The total cash collateral, per the surety agreement, was $2.5 million at December 31, 2017 , and 2016 . The total cash collateral is a component of the reclamation bond deposit in the consolidated balance sheets.

The reclamation bond deposit at December 31, 2017 and 2016 consisted of the following:



	2017		2016
Lexon surety bond cash collateral	$	2,500,000	$	2,500,000
Other cash reclamation bond deposits	122,544		122,544
Total reclamation bond deposit	$	2,622,544	$	2,622,544

7. Long-term Reclamation Liability and Retirement Obligation Asset

The Company is required to mitigate long-term environmental impacts by stabilizing, contouring, re-sloping, and re-vegetating various portions of our site after mining and mineral processing operations are completed. These reclamation efforts are conducted in accordance with plans reviewed and approved by the appropriate regulatory agencies.

We have accrued a long-term liability of $7.4 million and $7.4 million as of December 31, 2017 , and 2016 , respectively, for our obligation to reclaim our mine facility based on our most recent reclamation plan, as revised, submitted and approved by the Nevada State Environmental Commission and Division of Environmental Protection. In conjunction with recording the reclamation liability, we recorded a retirement obligation asset that is being amortized over the period of the anticipated land disturbance. Such costs are based on management’s current estimate of then expected amounts for the remediation work, assuming the work is performed in accordance with current laws and regulations. It is reasonably possible that, due to uncertainties associated with the application of laws and regulations by regulatory authorities and changes in reclamation or remediation technology, the ultimate cost of reclamation and remediation could change in the future. We periodically review the accrued reclamation liability for information indicating that our assumptions should change. The accretion of the reclamation liability and the amortization of the retirement obligation asset for the years ended December 31, 2017 , 2016 , and 2015 , totaled $0.4 million , $1.0 million , $1.4 million , respectively, and were a component of environmental and reclamation expenses in the consolidated statements of operations.

Following is a reconciliation of the aggregate retirement liability associated with our reclamation plan for the mining projects for the years ended December 31, 2017 , 2016 and 2015 :



	2017		2016		2015
Long-term reclamation liability — beginning of period	$	7,353,346	$	6,827,568	$	5,908,700
Additional obligations incurred	—		340,000		659,295
Accretion of reclamation liability	64,334		185,778		259,573
Long-term reclamation liability — end of period	$	7,417,680	$	7,353,346	$	6,827,568

Following is a reconciliation of the aggregate retirement obligation asset associated with our mining projects for the years ended December 31, 2017 , 2016 , and 2015 :



	2017			2016			2015
Retirement obligation asset — beginning of period	$	617,126		$	1,107,120		$	1,619,101
Additional obligations incurred	—			340,000			659,295
Amortization of retirement obligation asset	(334,381		)	(829,994		)	(1,171,276		)
Retirement obligation asset — end of period	$	282,745		$	617,126		$	1,107,120

The increases in the reclamation liability and retirement obligation asset in 2016 is related to the net inflated and discounted increase of the asset and liability as a result of the increase in time before the Company expects to reclaim. In 2015, the increase related to additional County bonding.

11. Fair Value Measurements

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following table presents our assets and liabilities at December 31, 2016, which are measured at fair value on a recurring basis:



			Fair Value Measurements at December 31, 2016
	Total		Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

Total Liabilities	$	1,075,960	$	1,075,960	$	—	$	—

During the years ended December 31, 2017 and 2016 , there were no transfers of assets and liabilities between Level 1, Level 2, or Level 3.

There were no assets or liabilities at December 31, 2017 , which were measured at fair value on a recurring basis.

Following is a description of the valuation methodologies used for the Company’s financial instruments measured at fair value on a recurring basis as well as the general classification of such instruments pursuant to the valuation hierarchy.

Deposit on financing agreement (Varilease Finance) - The deposit is valued as the amount of the proceeds to be received by Varilease Finance from the sale of the remaining 208,200 shares of common stock to be sold by the maturity date. The Company calculated the proceeds received for the shares based on the price the noteholder received for those shares. These inputs included a quoted contractual terms and stock price. Because the inputs are quoted, this instrument is classified within Level 1 of the valuation hierarchy.

Notes payable (Daney Ranch Property) - The note payable is valued as the difference between the $0.9 million face amount as of December 31, 2016, reduced by the proceeds to be received by the noteholder from the sale of the remaining 630,700 shares of common stock to be sold through April 2017 by the noteholder. In January 2017 the note holder sold all their shares and the note was eliminated. The Company calculated the proceeds received for the shares based on the price the noteholder received for those shares. These inputs included a quoted contractual terms and stock price. Because the inputs are quoted, this instrument is classified within Level 1 of the valuation hierarchy.

Note payable (Dayton Property “Golden Goose”) - The note payable is valued as the difference between the $0.5 million face amount, reduced by the proceeds to be received by the noteholder from the sale of the 200,000 shares of common stock to be sold by the maturity date of January 2017, by the noteholder. In January 2017 the note holder sold all their shares and the note was eliminated. The Company calculated the proceeds received for the shares based on the price the noteholder received for those shares. These inputs included a quoted contractual terms and stock price. Because the inputs are quoted, this instrument is classified within Level 1 of the valuation hierarchy.

F-18

The carrying amount of cash and cash equivalents and trade payables approximates fair value because of the short-term maturity of these financial instruments. At December 31, 2017, and December 31, 2016, the fair value of long-term debt approximated $10.5 million and $7.6 million , respectively, as determined by borrowing rates estimated to be available to the Company for debt with similar terms and conditions. The fair value of assets and liabilities whose carrying value approximates fair value is determined using Level 2 inputs, with the exception of cash and cash equivalents (Level 1).

12. Segment Reporting

Our management organizes the Company into two operating segments, mining and real estate. Our mining segment consists of all activities and expenditures associated with mining, exploration and mine development. Our real estate segment consists of land, real estate rental properties and the Gold Hill Hotel. We evaluate the performance of our operating segments based on operating income (loss). All intercompany transactions have been eliminated, and intersegment revenues are not significant. Financial information relating to our reportable operating segments and reconciliation to the consolidated totals is as follows:

13. Net Loss Per Common Share

Basic earnings per share is computed by dividing net loss available to common shareholders by the weighted average number of shares of common stock outstanding during the period. Diluted loss per share reflects the potential dilution that could occur if stock options, warrants, and convertible securities to issue common stock were exercised or converted into common stock. The following is a reconciliation of the numerator and denominator used in the basic and diluted computation of net loss per share:



	Year Ended December 31,

14. Stock-Based Compensation

2011 Equity Incentive Plan

In 2011, the Company adopted the Comstock Mining Inc. 2011 Equity Incentive Plan (the “2011 Plan”). The maximum number of shares of the Company’s common stock that may be delivered pursuant to awards granted under the 2011 Plan is 1,200,000 shares of common stock. The plan provides for the grant of various types of awards, including but not limited to restricted stock (including performance awards), restricted stock units, stock options, and other types of stock-based awards.

Performance-based Restricted Stock

On February 23, 2015, the Board of Directors granted 12,000 shares of restricted stock (performance awards) to an employee under the 2011 Equity Incentive Plan. These awards and prior awards expired unvested.

The restricted stock fair value was $3.70 per share, (with a total grant date fair value of $44,400 ). The fair value was determined based on the fair value of the underlying common stock at the grant dates. The unvested restricted stock awards expired in May of 2017.

F-21

Information related to non-vested restricted stock issued under the 2011 Plan is as follows:



	Number of Shares		Weighted Average Grant Date Fair Value

Total net deferred tax assets	$	—		$	—

At December 31, 2017 , the Company had federal net operating losses of approximately $167.6 million that will begin to expire in 2023 and could be subject to certain limitations under section 382 of the Internal Revenue Code.

The Company has provided a valuation allowance at December 31, 2017 and 2016 of $44.0 million and $67.7 million , respectively, for its net deferred tax assets as it cannot conclude it is more likely than not that they will be realized. The valuation allowance changed by $(23.7) million , $4.4 million , and $3.5 million in 2017 , 2016 , and 2015 , respectively.

On December 22, 2017, the President signed into law Public Law No. 115-97, commonly referred to as the Tax Cuts and Jobs Act (TCJA), following its passage by the United States Congress. The TCJA makes significant changes to the U.S. federal income tax laws including among other changes a federal corporate tax rate reduction from 35% to 21% for tax years beginning after December 31, 2017, repeal of the corporate AMT tax system, and immediate expensing of certain types of business assets placed in service after September 27, 2017. Due to the impact of the Company’s full valuation allowance on net deferred tax assets, the TCJA has minimal impact on the Company’s provision for income taxes. Staff Accounting Bulletin No. 118 ("SAB 118") was issued to address the application of US GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the TCJA. As of the date of this filing, we have not completed our accounting for the tax effects of the TCJA. In accordance with SAB 118, we have calculated our best estimate of the impact of the TCJA in our year end income tax provision in accordance with our understanding of the law and guidance available as of the date of this filing and as a result have recorded a provisional amount of $27.3 million as additional income tax expense in the fourth quarter of 2017. The provisional amount related to the remeasurement of certain deferred tax assets and liabilities, based on the rates at which they

F-23

are expected to reverse in the future, was $27.3 million . The provisional amounts are subject to revisions as we complete our analysis of the TCJA, collect and prepare necessary data, and interpret any additional guidance issued by the U.S. Treasury Department, Internal Revenue Service (“IRS”), FASB, and other standard-setting and regulatory bodies. Any subsequent adjustment to these amounts will be recorded to tax expense in the quarter when the analysis is complete. Our accounting for the tax effects of the TCJA will be completed during the measurement period, which should not extend beyond one year from the enactment date.

As of December 31, 2017 and 2016 , the Company did not have any unrecognized tax benefits. The Company’s policy is to recognize interest and penalties related to income tax matters in income tax expense. The Company currently has no federal or state tax examinations in progress nor has it had any federal or state tax examinations since its inception. The Company is subject to U.S. federal and state income tax examination for tax years 2014 and forward.

16. Related Party Transactions

Northern Comstock LLC

The Company has an operating agreement with Northern Comstock LLC, an entity controlled by a related party. As part of the operating agreement, the Company obtained the exclusive rights of production and exploration on certain parcels in Storey County, Nevada. The terms of this agreement were amended on August 27, 2015, and September 28, 2015 (the “Amendments”), with the other members of its Northern Comstock LLC joint venture. The Amendments resulted in reduced capital contribution obligations of the Company from $31.05 million down to $9.75 million . The terms of the Amendments provide that the Company will make monthly cash capital contributions of $30,000 and annual capital contributions in the amount of $482,500 payable in stock or cash, at the Company's option, unless the Company has cash or cash equivalents in excess of $10,500,000 on the date of such payments, wherein the Company would then be required to pay in cash or in certain circumstances, the Company’s common stock. The number of shares to be delivered is calculated by dividing the amount of the capital contribution by the volume-weighted average closing price of the Company’s common stock on its primary trading market for the previous 20 consecutive trading days prior to such capital contribution. The Operating Agreement also provides for a one-time acceleration of $812,500 of the capital contributions payable when the Company receives net cash proceeds from sources other than operations that exceed $6,250,000 . The agreement also includes an ongoing acceleration of the Company’s capital contribution obligations equal to 3% of the net smelter returns generated by the properties subject to the Northern Comstock LLC joint venture. The Operating Agreement also provides that if the Company defaults in its obligation to make the scheduled capital contributions, then the remaining capital contribution obligations may be converted into the principal amount of a 6% per annum promissory note payable by the Company on the same schedule as the capital contributions, secured by a mortgage on the properties subject to the Northern Comstock LLC joint venture. The operating agreement requires that these capital contributions commence in October 2015, and end in September 2027, unless prepaid by the Company.

The Company made a payment in stock in the amount of $482,500 with the number of shares being 502,604 and 243,025 under the Northern Comstock Joint Venture agreement during the years ended December 31, 2017 and 2016, respectively. During the year ended December 31, 2017 , 2016 and 2015 , the Company recognized expense of $0.8 million , $0.8 million and $0.8 million, respectively.

17. Commitments and Contingencies

The Company leases certain properties under operating leases expiring at various dates through 2023. Future minimum annual lease payments under these existing lease agreements are as follows as of December 31, 2017 :



Year Ended December 31,	Leases
2018	$	26,400
2019	28,800
2020	28,880
2021	30,000
2022	30,000
Thereafter	54,000
	$	198,080

Expense under operating leases for the years ended December 31, 2017 , 2016 and 2015 was $0.1 million, $0.1 million and $0.1 million, respectively.

The Company has minimum royalty obligations with certain of its mineral properties and leases. Minimum royalty payments were $55,800 in 2017 . For most of the mineral properties and leases, the Company is subject to a range of royalty obligations once production commences. These royalties range from 0.5% to 5% of net smelter revenues (NSR) from minerals produced on the properties with the majority being under 3% . Some of the factors that will influence the amount of the royalties include ounces extracted and prices of gold. Royalty expense, including both NSR and minimum royalty obligations, was $55,800 , $0.1 million, and $0.2 million for the years ended 2017 , 2016 , and 2015 , respectively.

F-25

From time to time, we are involved in lawsuits, claims, investigations and proceedings that arise in the ordinary course of business. There are no matters pending that we expect to have a material adverse impact on our business, results of operations, financial condition or cash flows.

The Company will not become a member of Pelen, LLC until the member has sold the shares for proceeds of at least $585,000 . Upon the member's receipt of $585,000 of total proceeds, the Company would obtain a 25% membership interest in Pelen, LLC.

ITEM 9A. CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Annual Report, management performed, with the participation of our Principal Executive Officer and our Principal Financial Officer, an evaluation of the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Our disclosure controls and procedures are designed to ensure that information required to be disclosed in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the Exchange Act and SEC’s rules, and that such information is accumulated and communicated to our management, including our Principal Executive Officer, to allow timely decisions regarding required disclosures. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Our Principal Executive Officer concluded that, as of December 31, 2017 , our disclosure controls and procedures were effective.

Design and Evaluation of Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Exchange Act Rule 13a-15(f) and 15d-15(f). Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2017 . In making this assessment, management used the criteria for effective internal control over financial reporting described in the “Internal Control-Integrated Framework” (2013) set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on the assessment, management concluded that, as of December 31, 2017 , our internal control over financial reporting was effective based on those criteria.

Changes in Internal Control Over Financial Reporting

During the quarter ending December 31, 2017 , there was no change in our internal control over financial reporting that materially affected, or is reasonably likely to materially affect our internal control over financial reporting.

F-28

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Our management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company in accordance with and as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934 (“Exchange Act”). Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Our internal control over financial reporting includes those policies and procedures that:

(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;

(ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements; and

(iii) provide reasonable assurance regarding prevention or timely detection of unauthorized transactions.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

Management has evaluated the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017 . Management based its assessment on the framework set forth in COSO’s Internal Control – Integrated Framework (2013) in conjunction with Securities and Exchange Commission Release No. 33-8820 entitled “Commission Guidance Regarding Management’s Report on Internal Control Over Financial Reporting Under Section 13(a) or 15(d) of the Securities and Exchange Commission”. Based on the assessment, management concluded that, as of December 31, 2017 , our internal control over financial reporting was effective to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States. The concept of reasonable assurance is based on the recognition that there are inherent limitations in all systems of internal control. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

We believe that internal control over financial reporting is effective as of December 31, 2017 .

Corporate Governance

We are managed under the direction of the Board of Directors, which has adopted Corporate Governance Guidelines to set forth certain corporate governance practices. The Corporate Governance Guidelines are available on our website at

http://www.comstockmining.com/files/corporate-governance/ComstockMining_CorporateGovernanceGuidelines_20101231.pdf .

The information contained on our website is not part of this annual report on Form 10-K. These guidelines cover such matters as purpose and powers, Board size and composition, director qualifications, meetings, procedures, management reporting to the Board, director orientation and continuing education programs, director and executive officer compensation, required director responsibilities, director access to officers, employees and others, and discretionary activities that our Board or the appropriate committee should periodically consider undertaking. Each committee is authorized to exercise all power of our Board with respect to matters within the scope of its charter.

F-31

The Corporate Governance Guidelines require, among other things, that:


•	a majority of the directors shall be independent within the NYSE American listing standards;


•	a director shall advise our Nominating and Governance Committee (and receive written confirmation from counsel for the Company that there are no legal or regulatory impediments to such service) prior to accepting an invitation to serve on another public company board;


•	if a member of the Audit and Finance Committee simultaneously serves on an audit committee of more than three public companies, our Board must determine that such simultaneous service would not impair the ability of such member to effectively serve on the Audit and Finance Committee and make disclosure of such determination either in our Annual Report on Form 10-K or on or through our website;


•	our Board shall meet in regular sessions at least four times annually (including telephonic meetings );

•

our independent directors meet on a regular basis as often as necessary to fulfill their responsibilities, including at least annually in executive session without management present; and our Board shall be comprised of that number of directors (but not less than three nor more than nine) as shall be determined from time to time by the Board (with the Board's sense that five to seven directors is the right size for the Board, but that a slightly larger size may be justifiable in order to accommodate the availability of an outstanding candidate).

Our Corporate Governance Guidelines and committee charters are not intended to, and do not, expand or increase the duties, liabilities or responsibilities of any director under any circumstance beyond those that a director would otherwise have under applicable laws, rules and regulations in the absence of such Corporate Governance Guidelines or committee charters.

Independence of Directors

The Board of Directors has determined that Messrs. Kappes, Nance and Reseigh are generally “independent” directors within the listing standards of the NYSE American and the independence standards of our Corporate Governance Guidelines. Messrs. Reseigh and Nance are also independent within the standards set forth in Rule 10A-3 of the Securities Exchange Act of 1934, as amended (the "Exchange Act").

Generally, in order for a director to be considered “independent” by the Board of Directors, he or she must (1) be free of any relationship that, applying the rules of the NYSE American, would preclude a finding of independence and (2) not have any relationship (either directly or as a partner, shareholder or officer of an organization) with us or any of our affiliates or any executive officer of us or any of our affiliates (exclusive of relationships based solely upon investment) that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. On an annual basis, each director and executive officer is obligated to disclose any transactions with our Company and any of its subsidiaries in which a director or executive officer, or any member of his or her immediate family, have a direct or indirect material interest. In evaluating the materiality of any such relationship, the Board of Directors takes into consideration whether disclosure of the relationship would be required by the proxy rules under the Exchange Act. If disclosure of the relationship is required, the Board of Directors must make a determination that the relationship is not material as a prerequisite to finding that the director is “independent.”

Board of Directors Meetings

The Board of Directors meets on a regularly scheduled basis during the year to review significant developments affecting us and to act on matters requiring Board of Directors’ approval, and may hold special meetings between scheduled meetings when appropriate. During 2017 , the Board of Directors and its committees held 9 meetings of all the committees of the Board of Directors on which the directors then served. The directors attended over 82% of the aggregate of (1) the total number of meetings of all committees of the Board of Directors on which the director then served and (2) the total number of meetings of the Board of Directors.

Board of Directors Leadership Structure and Role in Risk Oversight

Our Company is led by Corrado De Gasperis, who has served as President, and Chief Executive Officer since April 2010 and Executive Chairman since September 2015.

The Board of Directors believes that the current Board leadership structure, in which the roles of Chairman and Chief Executive Officer are held by one person, is appropriate for the Company and its shareholders at this time. The current Board leadership structure is believed to be appropriate because it demonstrates to our employees, suppliers, customers, and other shareholders that the Company is under strong leadership, with a single person setting the tone and having primary responsibility for managing the Company’s operations. The Board will continue to reexamine our corporate governance

F-32

policies and leadership structure on an ongoing basis to ensure that they continue to meet the Company’s needs. The Company will review these policies and may adopt a different approach in the future if circumstances warrant a change.

The Board is responsible for overseeing risk management, and receives periodic reports from management. Management and the Board are focused on the vision for the Company, and enhancing shareholder value, management and strategic planning and oversight of Company operations. We believe that our directors provide effective oversight of the risk management function, especially through dialogue between the Board and our management.

Executive Officers

The Company had two executive officers during 2017 , Mr. De Gasperis, the Executive Chairman, Chief Executive Officer and President of the Company, who serves as the Company’s principal executive officer, and Timothy D. Smith, who serves as the Company’s Chief Accounting Officer and Secretary. See Mr. De Gasperis’ and Mr. Smith’s biographical information under Directors and Executive Officers section of Item 10.

Code of Conduct and Ethics

The Code of Conduct and Ethics applies to all employees, including senior executives, and all directors. It is intended, at a minimum, to comply with the listing standards of the NYSE American, the Sarbanes-Oxley Act of 2002 and the SEC rules adopted thereunder. Only our Board or the Audit and Finance Committee may waive the provisions of our Code of Conduct and Ethics for executive officers and directors. Our Code of Conduct and Ethics constitutes a code of ethics for purposes of Item 406 of Regulation S-K, and is posted on our website at www.comstockmining.com.

The Board has established three standing committees (the Audit and Finance Committee, the Compensation Committee and the Nominating and Governance Committee), and periodically establishes other committees, in each case so that certain important matters can be addressed in greater depth than may be possible in a meeting of the entire Board. Under the committee charters described below, members of the three standing committees must be independent directors within the meaning of the listing standards of the NYSE American. Further, members of the Audit and Finance Committee must be independent directors within the meaning of the Sarbanes-Oxley Act of 2002 and Rule 10A-3 under the Securities Exchange Act of 1934, must satisfy the expertise requirements of the listing standards of the NYSE American and must include at least on "audit committee financial expert" within the meaning of SEC rules. Our Board has determined that the three standing committees currently consist of members who satisfy such requirements.

Audit and Finance Committee

The Audit and Finance Committee assists our Board in discharging and performing its duties and responsibilities with respect to the financial affairs of the Company.

Without limiting the scope of such activities, the Audit and Finance Committee has responsibility to, among other things:


•	select, retain, determine appropriate compensation of (and provide for payment of such compensation), evaluate and, as appropriate, terminate and replace the independent registered public accounting firm;


•	review and, as appropriate, approve, prior to commencement, all audit and non-audit services to be provided by the independent registered public accounting firm;


•	review regularly with management, the director of internal audits, where applicable, and the independent registered public accounting firm any audit problems or difficulties and management’s responses thereto;


•	resolve or direct the resolution of all material disagreements between management and the independent registered public accounting firm regarding accounting and financial reporting;

•

review with management and the independent registered public accounting firm, among other things, all reports delivered by the independent registered public accounting firm with respect to critical accounting policies and practices used or to be used, alternative treatments of financial information available under generally accepted accounting principles and other material written communications between the independent registered public accounting firm and management


•	review with management major issues regarding auditing, accounting, internal control and financial reporting principles, policies and practices and regulatory and accounting initiatives, and presentation of financial statements,

F-33

and major issues as to the adequacy of the internal controls and any special audit steps adopted in light of material control deficiencies;


•	meet at least once annually with management and the independent registered public accounting firm in separate sessions;


•	review, prior to filing with the SEC, all annual and quarterly reports (and all interim reports on Form 8-K to be filed that contain financial disclosures of similar scope and magnitude as annual reports and quarterly reports).


•	assess at least annually the adequacy of codes of conduct, including codes relating to ethics, integrity, conflicts of interest, confidentiality, public disclosure and insider trading and, as appropriate, adopt changes thereto;


•	direct the establishment and maintenance of procedures for the receipt and retention of, and the treatment of, complaints received regarding accounting, internal control or auditing matters; and


•	direct the establishment and maintenance of procedures for the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters.

Members of the Audit and Finance Committee are William Nance, and Robert Reseigh. The Board has determined that each member of the Audit and Finance Committee meets the financial literacy requirements of the NYSE American and SEC, and that no members of Audit and Finance Committee violate the prohibition on serving as an Audit and Finance Committee member due to having participated in the preparation of our financial statements at any time during the past three years.. William Nance qualifies as an “audit committee financial expert” as that term is defined in the rules and regulations of the SEC, and therefore meets the NYSE American financial sophistication requirement for at least one Audit and Finance Committee member. The designation of William Nance as an “audit committee financial expert” does not impose on him any duties, obligations or liability that are greater than those that are generally imposed on him as a member of our Audit and Finance Committee and the Board, and his designation as an “audit committee financial expert” pursuant to this SEC requirement does not affect the duties, obligations or liability of any other member of our Audit and Finance Committee or the Board.

Compensation Committee

The Compensation Committee assists our Board in discharging and performing its duties with respect to management compensation, succession planning, employee relations and employee benefits, plan administration and director compensation.

Without limiting the scope of such activities, the Compensation Committee shall, among other things:


•	review and approve annually the goals and objectives relating to the compensation of the Chief Executive Officer, evaluate the performance of the Chief Executive Officer in light of such goals and objectives and annually determine the compensation of the Chief Executive Officer based on such evaluation;


•	review and approve, as appropriate, annually the compensation of the other executive officers and directors and review compensation of other members of senior management and other employees generally;


•	assess organizational systems and plans, including those relating to management development and succession planning;


•	administer stock-based compensation plans and assess compensation arrangements, plans, policies and programs and benefit and welfare plans and programs; and


•	review the Compensation Discussion and Analysis for inclusion in the annual proxy statements or annual report, as the case may be.

Members of the Compensation Committee are William Nance (chair) and Robert Reseigh, each of whom satisfies the independence requirements of NYSE American and SEC rules and regulations. Each member of our Compensation Committee is a non-employee director, as defined pursuant to Rule 16b-3 promulgated under the Exchange Act, and an outside director, as defined pursuant to Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”).

Compensation Committee Interlocks and Insider Participation

No member of the Compensation Committee was at any time an officer or employee of the Company, nor is any member of the Compensation Committee related to any other member of the Compensation Committee, any other member of the Board of Directors or any executive officer of the Company. No executive officer of the Company served as a director or member of the compensation committee of another entity, one of whose executive officers is a member of the Company’s Compensation Committee.

F-34

The Nominating and Governance Committee

The Nominating and Governance Committee assists our Board in discharging and performing its duties and responsibilities with respect to nomination of directors, selection of committee members, assessment of performance of our Board and other corporate governance matters. Without limiting the scope of such activities, the Nominating and Governance Committee shall, among other things:


•	review candidates for nomination for election as directors submitted by directors, officers, employees and stockholders; and


•	review at least annually the current directors of our Board to determine whether such individuals are independent under the listing standards of the NYSE American and the SEC rules under the Sarbanes-Oxley Act of 2002 (and non-employee directors (as defined under Exchange Act Rule 16b-3) and outside directors (as defined under Internal Revenue Code Section 162 (m))).

Members of the Nominating and Governance Committee are William Nance (chair), Daniel Kappes and Robert Reseigh, each of whom satisfies the independence requirements of NYSE American and SEC rules and regulations.

Item 11. Executive Compensation

COMPENSATION DISCUSSION AND ANALYSIS

This compensation discussion and analysis explains the material elements of the compensation for our named executive officers.

The Company’s philosophy is to align total compensation of its employees, including the named executive officers, with the achievement of the Company’s goals, most importantly, creating sustainable wealth. The adoption and implementation of compensation programs is intended to support that philosophy and the interest of the Company and its stockholders by providing appropriate forms of cash and stock-based compensation alternatives that strengthen the ability of the Company to attract, motivate and retain employees and others who focus their efforts and abilities on realizing the Company’s objectives, and are in a position to impact the financial and operational performance of the Company.

What are our compensation principles?

The Compensation Committee (for purposes of this Compensation Discussion and Analysis section, the “Committee”) designs and oversees the Company’s compensation policies and approves compensation for our named executive officers. Our goal is to create compensation plans linked to enhancing shareholder value. We strive to align the interests of shareholders with those of employees at all levels of the organization. Our focus is on achieving sustainable results through the systematic and methodical implementation of our strategic plan. These principles are inherently long-term in nature. To accomplish this, our plans are designed to:


•	Support our business strategy - We align our programs with business strategies focused on long-term growth and enhanced shareholder value. Our compensation plans allow our executives to share in that wealth creation and support an environment that promotes improvement and breakthrough performance.


•	Pay for Performance - A substantial majority of our executive pay is dependent upon the achievement of specific corporate performance goals. As a result, individual performance as it relates to compensation is only relevant insofar as it advances the goals of the Company. Our plans will result in realizing higher compensation when goals are met and lower compensation when goals are not met.


•	Pay Competitively - We establish compensation levels that are designed to meet or exceed the needs of our employees. We also assess them against companies that we believe compete with us for human capital. In this context, we believe we are more than competitive with those competing companies.

What are our compensation objectives?

Central to the Company’s goal of wealth creation is the achievement of predictable, sustainable growth of throughput (that is, the rate at which our system generates cash as determined by the constraint in the system (i.e., the system’s “weakest link”) identified by management). Accordingly, it is important to the Company that non-throughput based measurements are eliminated from decision-making or minimized (for example, when required by law). Additionally, we seek to use Statistical Process Control (SPC) on the most critical, interdependent processes to promote stability and predictability in our operations.

In designing our compensation plans, our overreaching objectives are to:


•	Drive superior throughput-based financial performance - we design programs that encourage our executives to achieve or exceed goals and share in that value creation.


•	Attract, retain and motivate the right people in the right role, within the broader system design - we require independent and interdependent performance and allow our executives to share in the value created based on the system’s performance.


•	Align our executives with shareholders’ long-term interests by building the opportunity for significant ownership of Company stock through our compensation programs, vesting only on the systems achievement of value enhancing performance objectives.


•	Focus on full alignment to the goal of the system, our executives vest only when the systems objectives and goals are achieved. The objectives and the vesting do not vary from the rest of program participants.

F-36

Our compensation plans are intended to serve both named executive officers and employees generally. Accordingly, we currently offer two components of compensation as explained below:

Base Compensation . Base compensation should both reflect the Company’s appreciation of the employee’s competencies (with some but not absolute consideration to the market’s valuation of those competencies) and meet the needs of the employee for stability. The objective should be that base compensation is not only enough to meet the basic needs for employees and their families, but is also enough to take the issue of money-as-a-motivator off the table.

Stock-based Compensation . We acknowledge the risk that certain stock-based compensation programs could fail to completely satisfy the compensation principles previously described because the various instruments typically used (options, warrants, time-based grants, etc.) may present no real correlation to performance and, in particular, performance against a precisely defined goal and duration. However, we believe that stock-based compensation tied to the achievement of precise goals and the Company’s strategic plan does provide meaningful rewards for stable, measurable progress. Accordingly, we adopted a shareholder approved, equity incentive plan based solely on performance-based vesting.

The following is a summary of the principal features of the 2011 Equity Incentive Plan (the “2011 Plan”) and its operation and is qualified by reference to the full text of the 2011 Plan.

Any employee of Comstock or a subsidiary of Comstock providing services to Comstock or any of its subsidiaries who is specifically identified by the Committee, and any non-employee director of Comstock or any of its subsidiaries is eligible to receive awards under the 2011 Plan. While all of our employees and non-employee directors would be eligible to participate in the 2011 Plan, most awards under the 2011 Plan have been made to our senior officers, managers, and technical and professional personnel.

The maximum number of shares of the Company’s common stock that may be delivered pursuant to awards granted under the 2011 Plan is 1,200,000 shares of common stock. No more than 1,200,000 shares of common stock may be issued under the 2011 Plan or transferred upon exercise or settlement of incentive stock options. Any shares subject to an award under the 2011 Plan that are forfeited or terminated, expire unexercised, lapse or are otherwise canceled in a manner such that the shares of common stock covered by such award are not issued may be used again for awards under the 2011 Plan.

As of December 31, 2017 , 425,840 shares remained available for issuance under the 2011 Plan. All of the awards to date have been made in the form of restricted stock. All unvested restricted stock awards granted under the 2011 Plan are subject to the following vesting requirements:

For stock granted in 2012 and earlier:

•

the final two-fifths (2/5) of the restricted shares vest on the date of certification by the Committee of the attainment of both (A) the validation through a NI 43-101 of qualified resources (at least measured and indicated) and reserves (proven and probable), in each case including those previously validated, of the Company aggregating 3,250,000 ounces of gold equivalent and (B) the completion of three months (that is, ninety (90) days) of consecutive mining operations at an annual production rate of 20,000 ounces of gold equivalent (the Company produced at greater than this rate in 2014).

For stock granted in 2013:

• Completion of one year of service with the Company (for employees that received stock grants in 2013); and

•

In addition, if a change in control of the Company (as defined in the 2011 Plan) occurs, then the shares would vest immediately and, following the date on which the participant’s employment is terminated by the Company without cause or following the participant’s disability, the portion of the award that would vest upon achieving the next objective shall vest at the time of termination. The unvested awards expire five years after the grant date.

F-37

Who are our named executive officers?

The Company’s named executive officers for 2017 were:



Name		Title
Corrado De Gasperis		Executive Chairman, Chief Executive Officer and President
Timothy D. Smith		CAO and Secretary

How do we assure that our compensation program keeps our named executive officers focused on long-term success?

We assure that our compensation programs keep our named executive officers focused on the long-term success of our Company by making a substantial portion of their long-term pay subject to the achievement of specific, longer-term, strategic, company wide performance objectives and by granting stock-based awards with vesting criteria fully linked with those, longer term, measurable strategic objectives. Moreover, the value of such stock-based awards will likely only increase based on the long-term performance of the Company as compared to other investment alternatives.

How is competitiveness established?

The Committee structures executive compensation so that targeted total cash compensation and longer-term stock based compensation opportunities are competitive with comparable positions at companies that we compete with for human capital, basically mining and construction-type companies based in Nevada. When considering what is competitive for the Company, the Committee considered the complexity of starting up a new, industrial mine, the breakthrough’s required for success, the entrepreneurial and team building competencies needed, the complexities of the regulatory and political environments and the extensive interdependencies required with all stakeholders, including the people required for operating the system. The Company does not use benchmarking against a peer group or otherwise.

In setting 2017 base salaries, target total cash compensation and target total direct compensation, the Committee considered the potential value creation inherent in our stated objectives, the time period required for achieving those objectives and the associated risks.

How is compensation established for our named executive officers?

The Committee does not rely exclusively on existing market data in establishing target levels of compensation. The Committee also does not employ a rigid or formulaic process to set pay levels, but does utilize market data as one of many tools to assist the Committee. In setting compensation levels, the Committee considers the following factors:


•	market data;


•	each executive’s competency;


•	each executive’s scope of responsibility and impact on the Company’s performance;


•	internal equity - an executive’s compensation relative to his or her peers in the system; and


•	the CEO’s recommendations for his senior team.

Each of our named executive officers’ performance is evaluated in light of our overall financial performance and the advancement of our strategic objectives approved by the Committee and the Board of Directors. For 2015, as in past years, the Committee structured a compensation package for our named executive officers comprised of base salary and benefits coupled with long-term incentives (restricted stock grants), which we believe provided an appropriate mix of financial security, wealth sharing.

F-38

Annual Compensation: Base Salaries

Base salary provides our named executive officers with a basic level of financial security and supports the Committee’s objectives in attracting and retaining top talent. Base salary increases for other named executive officers (other than our CEO) are recommended by our CEO and are reviewed and approved by the Committee.



Executive Officer	2017Annual Base Salary
Corrado De Gasperis ⁽¹⁾	$	288,000
Timothy D. Smith	110,000

_____________

⁽¹⁾ Mr. De Gasperis salary was reduced from $360,000 to $288,000 in conjunction with the Company's efforts to reduce general and administrative expenses.

The Committee is satisfied that each of the named executive officers’ salary is reasonable and appropriate.

Why did the Committee choose the performance metrics for the 2011 Equity Plan?

At the time the stock awards were granted, the Committee chose to align the vesting of stock awards directly to the achievement of the established goal of the strategic plan approved by the Board in April 2010. The goal of that business plan is to deliver stockholder value by validating qualified resources (measured and indicated) and reserves (proven and probable) of at least 3,250,000 gold equivalent ounces and achieve initial commercial mining with annual production rates of approximately 20,000 gold equivalent ounces. Accordingly, the restricted stock vests fully upon the achievement of both of these stated objectives. If the objectives are not achieved, the stock grant will not vest. In 2013, the Company achieved production rates of more than 20,000 gold equivalent ounces per year. The Committee chose to allow for partial vesting as the Company achieves intermediate objectives towards these goals, as stated above.

Benefits

The Company provides named executive officers with the same benefits provided to other Comstock employees namely, health and dental insurance (Company pays a portion of costs).

Post Termination Payments

We believe that we should provide reasonable severance benefits if an executive’s position is eliminated in the event of a change in control or, in the absence of a change in control, in certain other circumstances. It is our belief that the interests of shareholders are best served if our senior management is focused on the performance of the Company without the distraction and uncertainty that the lack of such protection would invite. We also believe that providing these benefits helps to facilitate the recruitment of talented executives, and that, relative to the overall value of any potential transaction, these potential benefits are appropriately sized.

The employment agreements for Mr. De Gasperis and Mr. Smith include severance arrangements. For additional information with respect to these arrangements, please see “Employment, Retirement and Severance Plans and Agreements”.

ADDITIONAL INFORMATION

We believe this additional information may assist you in better understanding our compensation practices and principles.

F-39

Role of the Committee and the CEO

The Committee, consisting entirely of independent Directors, is responsible for executive compensation. As part of the compensation-setting process each year, the Committee meets periodically with the CEO to review the Company’s progress toward its stated strategic objectives and receives comments from members of the Board of Directors. The CEO recommends to the Committee the compensation amounts for each of our named executive officers, other than himself.

While the Committee will ask for advice and recommendations from the CEO, the Committee is responsible for executive compensation and as such:


•	Sets named executive officer base salaries;


•	Reviews the business and financial plan and progress toward strategic goals, performance measures and action plans for our business, which are reviewed by, and subject to approval of, the entire Board of Directors;


•	Reviews annual and long-term performance against goals and objectives;


•	Reviews contractual agreements and benefits, including supplemental retirement and any payments which may be earned upon termination, and makes changes as appropriate;


•	Reviews incentive plan designs, ensures alignment and makes changes as appropriate; and


•	Reviews total compensation to ensure compensation earned by named executive officers is fair and reasonable relative to corporate and individual performance.

The Committee is authorized to retain compensation consultants or advisors but does not presently do so. Any such consultant or advisor selected by the Committee would only be selected if the Committee determined that such consultant or advisor is independent from our management pursuant to SEC and NYSE American standards.

Deductibility of Compensation

In determining the total compensation of each named executive officer, the Committee considers the tax deductibility of compensation. The Committee believes it is generally in the interests of the Company and our shareholders to provide compensation that is tax deductible by the Company. While the Committee intends that compensation be deductible, there may be instances where potentially non-deductible compensation is justifiably provided to reward executives consistent with our compensation philosophy for each compensation element.

Advisory Vote on Executive Compensation

As required by the Dodd Frank Wall Street Reform and Consumer Protection Act of 2010 and the rules and regulations promulgated by the SEC pursuant thereto, we included a proposal for a non-binding advisory resolution approving the compensation of our named executive officers for 2016 in our proxy statement for our 2017 annual meeting of stockholders. The proposal was overwhelmingly supported by stockholders with approval in excess of 96% (85,773,472 votes in favor and 3,547,920 votes against).

The Committee considered the results of the advisory vote in reviewing our executive compensation program, noting the high level of shareholder support, and elected to continue the same principles and objectives in determining the types and amounts of compensation to be paid to our named executive officers in 2017 . The Committee will continue to focus on responsible executive compensation practices that attract, motivate and retain high performance executives, reward those executives for the achievement of long-term performance and support our other executive compensation objectives.

COMPENSATION COMMITTEE REPORT

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis section of this annual report on Form 10-K with management and, based on such review and discussion, recommended to the Board of Directors that it be included in this annual report on Form 10-K.

The terms of each of Mr. De Gasperis employment agreement is described in detail in Employment, Retirement and Severance Plans and Agreements below.

Current Equity Compensation Program

In 2011, the Company adopted the 2011 Plan. For a description of the 2011 Plan, please see “Compensation Discussion and Analysis - Stock-Based Compensation.” The 2011 Plan replaced the equity plans previously adopted by the Company, including, without limitation, those adopted in 2005 and 2006.

As of December 31, 2017 , 774,160 shares have been issued and outstanding under the program and 746,160 shares have vested and 0 are unvested. On December 21, 2011, the Board of Directors granted 942,000 shares of restricted stock to certain employees under the 2011 Plan. Of these shares, Mr. De Gasperis received a grant of 550,000 shares (of which, 330,000 shares have vested and 220,000 expired).

Prior Equity Compensation Programs

In 2005, the Company adopted a stock option and incentive plan that was approved by our stockholders in October 2005. That plan expired in June 2011 upon the adoption of the 2011 Plan with no awards having been issued thereunder.

In 2006, the Company adopted another stock option and incentive plan (“2006 Plan”) that was approved by our stockholders in November 2006. The plan provided for a maximum of 800,000 shares of common stock to be issued (the shares reflect the adjustment due to the reverse stock split). Under the 2006 Plan, options, stock and other awards could have been granted to employees and non-employee directors. Stock options granted under the 2006 Plan generally vested over three years and expired ten years from the date of the grant. Options to purchase an aggregate of 10,000 fully vested options remain outstanding under the 2006 Plan. The 2006 Plan expired upon the adoption of the 2011 Plan.

Item 13. Certain Relationships and Related Transactions, and Director Independence.

The Board of Directors has adopted a written related person transaction policy that governs the review, approval or ratification of covered related person transactions. The Audit and Finance Committee manages this policy. The policy generally provides that we may enter into a related person transaction only if:


•	the Audit and Finance Committee approves or ratifies such transaction in accordance with the guidelines set forth in the policy and the transaction is on terms comparable to those that could be obtained in arm’s length dealings with an unrelated third party; or


•	the transaction is approved by the disinterested members of the Board of Directors; or


•	the transaction involves compensation approved by our Compensation Committee.

For information about certain relationships between our director nominees and the Company, please see below:

Northern Comstock LLC

On October 20, 2010, the Company entered into an operating agreement (the “Operating Agreement”) to form Northern Comstock LLC (“Northern Comstock”) with Mr. John Winfield, the Company’s former Chairman and largest shareholder, and an entity controlled by Mr. Winfield, DWC Resources, Inc. (“DWC”). As part of the Operating Agreement, the Company obtained the exclusive rights of production and exploration on certain property formerly owned by DWC in Storey County, Nevada (the “DWC Property”) and two parcels leased by Mr. John Winfield in Storey County, Nevada from the Sutro Tunnel Company (the “Sutro Property”) and Virginia City Ventures (the “VCV Property”).

On August 27, 2015, the Company announced the terms of this agreement were amended on August 27, 2015, and September 28, 2015 (the “Amendments”), with the other members of its Northern Comstock LLC joint venture. The Amendments resulted in reduced capital contribution obligations of the Company from $31.05 million down to $9.75 million. The terms of the Amendments provide that the Company will make monthly cash capital contributions of $30,000 and annual capital contributions in the amount of $482,500 payable in stock or cash, at the Company's option, unless the Company has cash or cash equivalents in excess of $10,500,000 on the date of such payments, wherein the Company would then be required to pay in the form of cash, or in certain circumstances, the Company’s common stock. The number of shares to be delivered is calculated by dividing the amount of the capital contribution by the volume-weighted average closing price of the Company’s common stock on its primary trading market for the previous 20 consecutive trading days prior to such capital contribution. The Operating Agreement also provides for a one-time acceleration of $812,500 of the capital contributions payable when the Company receives net cash proceeds from sources other than operations that exceed $6,250,000. The agreement also includes an ongoing acceleration of the Company’s capital contribution obligations equal to 3% of the net smelter returns generated by the properties subject to the Northern Comstock LLC joint venture. The Operating Agreement also provides that if the Company defaults in its obligation to make the scheduled capital contributions, then the remaining capital contribution obligations may be converted into the principal amount of a 6% per annum promissory note payable by the Company on the same schedule as the capital contributions, secured by a mortgage on the properties subject to the Northern Comstock LLC joint venture. The operating agreement requires that these capital contributions commence in October 2015, and end in September 2027, unless prepaid by the Company.

F-45

Restructuring Agreement

On July 29, 2015, the Company entered into a Restructuring Agreement (the “Restructuring Agreement”), with Northern Comstock, the members of Northern Comstock and other entities affiliated with Mr. Winfield. Pursuant to the Restructuring Agreement, the Company’s shareholders party thereto agreed to consent to the proposed amendments to the Company’s then outstanding convertible preferred stock that resulted in the elimination of certain special voting rights and Board representation rights associated with the Company’s previously outstanding Series A-1 Convertible Preferred Stock and the Company and the other members of Northern Comstock agreed to amend the terms of the First Amendment.

Stockholders' Agreement

On July 29, 2015, the Company entered into a Stockholders’ Agreement (the “Stockholders’ Agreement”), with Mr. Winfield and entities affiliated with Mr. Winfield, pursuant to which the Company is generally prohibited from incurring indebtedness in excess of $5,000,000, subject to certain limited exceptions. The prohibition set forth in the Stockholders’ Agreement is substantially identical to the negative covenant previously contained in the documents governing the Company’s previously outstanding convertible preferred stock.

Item 14. Principal Accountants Fees and Services

The Audit and Finance Committee of the Board of Directors is composed of two independent directors and operates under a written charter adopted by the Board of Directors. The Audit and Finance Committee approves the selection of our independent registered public accounting firm.

Management is responsible for our disclosure controls, internal controls and the financial reporting process. The independent registered public accounting firm is responsible for performing an independent audit of our consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) and for issuing a report thereon. The Audit and Finance Committee’s primary responsibility is to monitor and oversee these processes and to report thereon to the Board of Directors. In this context, the Audit and Finance Committee has met privately with management and Deloitte & Touche LLP, our independent registered public accounting firm. Deloitte & Touche LLP has had unrestricted access to the Audit and Finance Committee.

The Audit and Finance Committee has discussed with Deloitte & Touche LLP the matters required to be discussed by Statement on Auditing Standards No. 61, as amended (AICPA, Professional Standards, Vol. 1, AU Section 380), as adopted by the Public Company Accounting Oversight Board in Rule 3200T, including the scope of the auditor’s responsibilities and whether there are any significant accounting adjustments or any disagreements with management.

The Audit and Finance Committee also has received the written disclosures and the letter from Deloitte & Touche LLP required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the Audit and Finance Committee concerning independence, and has discussed with Deloitte & Touche LLP that firm’s independence from the Company.

The Audit and Finance Committee has reviewed and discussed the consolidated financial statements with management and Deloitte & Touche LLP. Based on this review and these discussions, the representation of management that the consolidated financial statements were prepared in accordance with generally accepted accounting principles, and the report of Deloitte & Touche LLP to the Audit and Finance Committee, the Audit and Finance Committee recommended that the Board of Directors include the audited consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2017 filed with the SEC.

The Audit and Finance Committee also reviews with management and the independent registered public accounting firm the results of that firm’s review of the unaudited financial statements that are included in our quarterly reports on Form 10-Q.

Fees Billed by our Auditors

The Audit and Finance Committee reviews the fees charged by our independent registered public accounting firm. During the fiscal years ended December 31, 2017 and December 31, 2016 , we were billed the following fees set forth below in connection with services rendered by that firm to us.

F-46



	2017	2016
	Deloitte & Touche LLP	Deloitte & Touche LLP
Audit Fees	$214,869	$299,483
Tax Fees	19,889	18,907
Total fees	$234,758	$318,390

Audit Fees . Audit fees represent fees and expenses for professional services rendered by Deloitte & Touche LLP for the audit of our annual financial statements and the reviews of the financial statements included in our quarterly reports on Form 10-Q. This category also includes fees for audits provided in connection with statutory filings or services that generally only the principal auditor reasonably can provide to a client, registration statement, implementation of new financial and accounting reporting standards, consents, and assistance with and review of documents filed with the SEC.

Audit-Related Fees . Audit-related fees include consultation on proposed transactions.

Tax Fees. Tax fees include fees and expenses for professional services for original and amended tax returns, studies supporting tax return amounts as may be required by Internal Revenue Service regulations, claims for refunds, assistance with tax audits and other work directly affecting or supporting the payment of taxes.

Audit and Finance Committee Pre-Approval Policy

The charter of our Audit and Finance Committee provides that the duties and responsibilities of our Audit and Finance Committee include the pre-approval of all audits, audit-related, tax, and other services permitted by law or applicable SEC regulations (including fee and cost ranges) to be performed by our independent auditor. Any pre-approved services that will involve fees or costs exceeding pre-approved levels will also require specific pre-approval by the Audit and Finance Committee. Unless otherwise specified by the Audit and Finance Committee in pre-approving a service, the pre-approval will be effective for the 12-month period following pre-approval. The Audit and Finance Committee will not approve any non-audit services prohibited by applicable SEC regulations or any services in connection with a transaction initially recommended by the independent auditor, the purpose of which may be tax avoidance and the tax treatment of which may not be supported by the Internal Revenue Code and related regulations.

To the extent deemed appropriate, the Audit and Finance Committee may delegate pre-approval authority to the Chairman of the Audit and Finance Committee or any one or more other members of the Audit and Finance Committee provided that any member of the Audit and Finance Committee who has exercised any such delegation must report any such pre-approval decision to the Audit and Finance Committee at its next scheduled meeting. The Audit and Finance Committee will not delegate to management the pre-approval of services to be performed by the independent auditor.

Our Audit and Finance Committee requires that our independent auditor, in conjunction with our Chief Executive Officer and Chief Accounting Officer, be responsible for seeking pre-approval for providing services to us and that any request for pre-approval must inform the Audit and Finance Committee about each service to be provided and must provide detail as to the particular service to be provided. Our Audit and Finance Committee Chair and Audit and Finance Committee financial expert is William Nance.
