HL Hecla Mining Company

Legal, Regulatory and Market Risks

We are currently involved in ongoing legal disputes that may materially adversely affect us.

There are several ongoing legal disputes in which we are involved, including putative class action and derivative lawsuits filed against us involving our Nevada Operations unit, and additional actions may be filed against us and our board and certain officers.  We may be subject to future claims, including additional claims relating to our Nevada Operations unit. Further, we could experience claims regarding environmental damage or compliance, safety conditions or other matters at our mines.  The outcomes of these pending and potential claims are uncertain. We may not resolve these claims favorably. Depending on the outcome, these actions could cause adverse financial effects or reputational harm to us. If any of these disputes result in a substantial monetary judgment against us, are settled on terms in excess of our current accruals, or otherwise impact our operations (such as by limiting our ability to obtain permits or approvals), our financial results or condition could be materially adversely affected. For a description of some of the lawsuits and other claims in which we are involved, see Note 7 of Notes to Consolidated Financial Statements.

We are required to obtain governmental permits and other approvals in order to conduct mining operations.

In the ordinary course of business, mining companies are required to seek governmental permits and other approvals for continuation or expansion of existing operations or for the commencement of new operations. Obtaining the necessary governmental permits is a complex, time-consuming and costly process. The duration and success of our efforts to obtain permits are contingent upon many variables not within our control. Obtaining environmental permits, including the approval of reclamation plans, may increase costs and cause delays or halt the continuation of mining operations depending on the nature of the activity to be permitted and the interpretation of applicable requirements established by the permitting authority. Interested parties, including governmental agencies and non-governmental organizations or civic groups, may seek to prevent issuance of permits and intervene in the process or pursue extensive appeal rights. Past or ongoing violations of laws or regulations involving obtaining or complying with permits could provide a basis to revoke existing permits, deny the issuance of additional permits, or commence a regulatory enforcement action, each of which could have a material adverse impact on our operations or financial condition. In addition, evolving reclamation or environmental concerns may threaten our ability to renew existing permits or obtain new permits in connection with future development, expansions and operations. We cannot assure you that all necessary approvals and permits will be obtained and, if obtained, that the costs involved will not exceed those that we previously estimated. It is possible that the costs and delays associated with the compliance with evolving standards and regulations could become such that we would not proceed with a particular development or operation.

Specific examples of where we face permitting risk include the following:

See “Certain of our mines and exploration properties are located on land that is or may become subject to traditional territory, title claims and/or claims of cultural significance by certain Indigenous tribes, and such claims and the attendant obligations of the federal government to those tribal communities and stakeholders may affect our current and future operations.” and “Legal challenges could prevent the Rock Creek or Montanore projects from ever being developed.”

We are often required to post surety bonds or cash collateral to secure our reclamation obligations and we may be unable to obtain the required surety bonds or may not have the resources to provide cash collateral, and the bonds or collateral may not fully cover the cost of reclamation and any such shortfall could have a material adverse impact on our financial condition. Further, when we use the services of a surety company to provide the required bond for reclamation, the surety companies often require us to post collateral with them, including in the form of letters of credit. Currently we utilize letters of credit issued under our revolving credit facility as the source of such collateral, and as a result, there are less funds available for us to borrow under the facility for other purposes. In the event that we are unable to obtain necessary bonds or to post sufficient collateral, we may experience a material adverse affect on our operations or financial results. See the risk factors below, “Our Senior Notes and the guarantees thereof are effectively subordinated to any of our and our guarantors’ secured indebtedness to the extent of the value of the collateral securing that indebtedness,” “Any downgrade in the credit ratings assigned to us or our debt securities could increase future borrowing costs, adversely affect the availability of new financing and may result in increased collateral requirements under our existing surety bond portfolio,” and ““Mine closure and reclamation regulations impose substantial costs on our operations, and include requirements that we provide financial assurance supporting those obligations. These costs could significantly increase.”

We face substantial governmental regulation, including the Mine Safety and Health Act, various environmental laws and regulations and the 1872 Mining Law.

Our business is subject to extensive U.S. and foreign federal, state, provincial and local laws and regulations governing environmental protection, natural resources, prospecting, development, production, post-closure reclamation, taxes, labor standards and occupational health and safety laws and regulations, including mine safety, toxic substances and other matters. The costs associated with compliance with such laws and regulations are substantial. Possible future laws and regulations, or more restrictive interpretations of current laws and regulations by governmental authorities, could cause additional expense, capital expenditures, restrictions on or suspensions of operations and delays in the development of new properties.

U.S. surface and underground mines like those at our Lucky Friday, Greens Creek and Nevada Operations units are continuously inspected by the U.S. Mine Safety and Health Administration (“MSHA”), which inspections often lead to notices of violation under the Mine Safety and Health Act. Any of our U.S. mines could be subject to a temporary or extended shutdown as a result of a violation alleged by MSHA.

In addition, we have been and are currently involved in lawsuits or regulatory actions in which allegations have been made of our causing environmental damage, being responsible for environmental damage caused by others, violating environmental laws, or violating environmental permits, and we may be subject to similar lawsuits or actions in the future. Moreover, such environmental matters have involved both our current and historical operations as well as the historical operations of entities and properties we have acquired. See the risk factors below titled “Our operations are subject to complex, evolving and increasingly stringent environmental laws and regulations,” “Compliance with environmental regulations, and litigation based on such regulations, involves significant costs and can threaten existing operations or constrain expansion opportunities,” and “Our environmental and asset retirement obligations may exceed the provisions we have made.”

Some mining laws prevent mining companies that have been found to engage in bad conduct from obtaining future permits until remediation or restitution has occurred. If we are found to be responsible for any such conduct, our ability to operate existing projects or develop new projects might be impaired until we satisfy costly conditions.

We cannot assure you that we will at all times be in compliance with applicable laws, regulations and permitting requirements. Failure to comply with applicable laws, regulations and permitting requirements may result in lawsuits or regulatory actions, including orders issued by regulatory or judicial authorities causing operations to cease or be curtailed, which may require corrective measures including capital expenditures, installation of additional equipment or remedial actions. Any one or more of these liabilities could have a material adverse impact on our financial condition.

In addition to existing regulatory requirements, legislation and regulations may be adopted, regulatory procedures modified, or permit limits reduced at any time, any of which could result in additional exposure to liability, operating expense, capital expenditures or restrictions and delays in the mining, production or development of our properties. Mining accidents and fatalities or toxic waste releases, whether or not at our mines or related to metals mining, may increase the likelihood of additional regulation or changes in law or enhanced regulatory scrutiny. In addition, enforcement or regulatory tools and methods available to regulatory bodies such as MSHA or the U.S. Environmental Protection Agency (“EPA”), which have not been or have infrequently been used against us or the mining industry, in the future could be used against us or the industry in general.

From time to time, the U.S. Congress considers proposed amendments to the 1872 Mining Law, which governs mining claims and related activities on federal lands. The extent of any future changes is not known and the potential impact on us as a result of U.S. Congressional action is difficult to predict. Changes to the 1872 Mining Law, if adopted, could adversely affect our ability to economically develop mineral reserves on federal lands.

Our operations are subject to complex, evolving and increasingly stringent environmental laws and regulations. Compliance with environmental regulations, and litigation based on such regulations, involves significant costs and can threaten existing operations or constrain expansion opportunities.

Our operations, both in the United States and internationally, are subject to extensive environmental laws and regulations governing wastewater discharges; remediation, restoration and reclamation of environmental contamination; the generation, storage, treatment, transportation and disposal of hazardous substances; solid waste disposal; air emissions; protection of endangered and protected species and designation of critical habitats; mine closures and reclamation; and other related matters. In addition, we must obtain regulatory permits and approvals to start, continue and expand operations. New or revised environmental regulatory requirements are frequently proposed, many of which result in substantially increased costs for our business. See the risk factor above, “We are required to obtain governmental permits and other approvals in order to conduct mining operations” and the risk factor below, “Mine closure and reclamation regulations impose substantial costs on our operations, and include requirements that we provide financial assurance supporting those obligations. These costs could significantly increase.”

Our U.S. operations are subject to the Clean Water Act, which requires permits for certain discharges into waters of the United States. Such permitting has been a frequent subject of litigation and enforcement activity by environmental advocacy groups and the EPA, respectively, which has resulted in declines in such permits or extensive delays in receiving them, as well as the imposition of penalties for permit violations. In 2015, the regulatory definition of “waters of the United States” that are protected by the Clean Water Act was expanded by the EPA, thereby imposing significant additional restrictions on waterway discharges and land uses. However, in 2018, implementation of the relevant rule was suspended for two years, and in December 2019 a revised definition that narrows the 2015 version was implemented. Even with the recently narrowed rule, it is possible that in the future the definition could again be expanded, or states could take action to address a perceived fall-off in protection under the Clean Water Act, either of which could increase litigation involving water discharge permits, which may result in delays in, or in some instances preclude, the commencement or continuation of development or production operations. Enforcement actions by the EPA or other federal or state agencies could also result. Adverse outcomes in lawsuits challenging permits or failure to comply with applicable regulations or permits could result in the suspension, denial, or revocation of required permits, or the imposition of penalties, any of which could have a material adverse impact on our cash flows, results of operations, or financial condition. See Note 7 of Notes to Consolidated Financial Statements.

Some of the mining wastes from our U.S. mines currently are exempt to a limited extent from the extensive set of EPA regulations governing hazardous waste under the Resource Conservation and Recovery Act (“RCRA”). If the EPA were to repeal this exemption, and designate these mining wastes as hazardous under RCRA, we would be required to expend additional amounts on the handling of such wastes and to make significant expenditures to construct hazardous waste storage or disposal facilities. In addition, if any of these wastes or other substances we release or cause to be released into the environment cause or has caused contamination in or damage to the environment at a U.S. mining facility, that facility could be designated as a “Superfund” site under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (“CERCLA”). Under CERCLA, any present owner or operator of a Superfund site or the owner or operator at the time of contamination may be held jointly and severally liable regardless of fault and may be forced to undertake extensive remedial cleanup action or to pay for the cleanup efforts. The owner or operator also may be liable to federal, state and tribal governmental entities for the cost of damages to natural resources, which could be substantial. Additional regulations or requirements also are imposed on our tailings and waste disposal areas in Alaska under the federal Clean Water Act.

Legislative and regulatory measures to address climate change and greenhouse gas emissions are in various phases of consideration. If adopted, such measures could increase our cost of environmental compliance and also delay or otherwise negatively affect efforts to obtain permits and other regulatory approvals with regard to existing and new facilities. Proposed measures could also result in increased cost of fuel and other consumables used at our operations, including the diesel generation of electricity at our Greens Creek operation, used when we are unable to access hydroelectric power. Climate change legislation may also affect our smelter customers who burn fossil fuels, resulting in fewer customers or increased costs to us, and may affect the market for the metals we produce with effects on prices that are not possible for us to predict.

Adoption of these or similar new environmental regulations or more stringent application of existing regulations may materially increase our costs, threaten certain operating activities and constrain our expansion opportunities.

Some of our facilities are located in or near environmentally sensitive areas such as salmon fisheries, endangered species habitats, wilderness areas, national monuments and national forests, and we may incur additional costs to mitigate potential environmental harm in such areas.

In addition to evolving and expanding environmental regulations providing governmental authorities with the means to make claims against us, private parties have in the past and may in the future bring claims against us based upon damage to property and injury to persons resulting from the environmental, health and safety impacts of prior and current operations (including for exposure to or contamination by lead). Laws in the U.S. such as CERCLA and similar state laws may expose us to joint and several liability or claims for contribution made by the government (state or federal) or private parties. Moreover, exposure to these liabilities arises not only from our existing but also from closed operations, operations sold to third parties, or operations in which we had a leasehold, joint venture, or other interest. Because liability under CERCLA is often alleged on a joint and several basis against any property owner or operator or arranger for the transport of hazardous waste, and because we have been in operation since 1891, our exposure to environmental claims may be greater because of the bankruptcy or dissolution of other mining companies which may have engaged in more significant activities at a mining site than we but which are no longer available for governmental agencies or other claimants to make claims against or obtain judgments from. Similarly, there is also the potential for claims against us based on agreements entered into by certain affiliates and predecessor companies relating to the transfer of businesses or properties, which contained indemnification provisions relating to environmental matters. In each of the types of cases described in this paragraph, the government (federal or state) or private parties could seek to hold Hecla Limited or Hecla Mining Company liable for the actions of their subsidiaries or predecessors.

The laws and regulations, changes in such laws and regulations, and lawsuits and enforcement actions described in this risk factor could lead to the imposition of substantial fines, remediation costs, penalties and other civil and criminal sanctions against us. Further, substantial costs and liabilities, including for restoring the environment after the closure of mines, are inherent in our operations. There is no assurance that any such law, regulation, enforcement or private claim, or reclamation activity, would not have a material adverse effect on our financial condition, results of operations or cash flows.

Mine closure and reclamation regulations impose substantial costs on our operations and include requirements that we provide financial assurance supporting those obligations. These costs could significantly increase and we might not be able to provide financial assurance.

We are required by U.S. federal and state laws and regulations and by laws and regulations in the foreign jurisdictions in which we operate to reclaim our mining properties. The specific requirements may change and vary among jurisdictions, but they are similar in that they aim to minimize long term effects of exploration and mining disturbance by requiring the control of possible deleterious effluents and re-establishment to some degree of pre-disturbance land forms and vegetation. In some cases, we are required to provide financial assurances as security for reclamation costs, which may exceed our estimates for such costs. Conversely, our reclamation costs may exceed the financial assurances in place and those assurances may ultimately be unavailable to us.

The EPA and other state, provincial or federal agencies may also require financial assurance for investigation and remediation actions that are required under settlements of enforcement actions under CERCLA or equivalent state regulations. Currently there are no financial assurance requirements for active mining operations under CERCLA, and a lawsuit filed by several environmental organizations which sought to require the EPA to adopt financial assurance rules for mining companies with active mining operations was dismissed by a federal court. In the future, financial assurance rules under CERCLA, if adopted, could be financially material and adverse to us. See the risk factors above, “We are required to obtain governmental permits and other approvals in order to conduct mining operations” and “Our operations are subject to complex, evolving and increasingly stringent environmental laws and regulations. Compliance with environmental regulations, and litigation based on such regulations, involves significant costs and can threaten existing operations or constrain expansion opportunities.”

 Our environmental and asset retirement obligations may exceed the provisions we have made.

We are subject to significant environmental obligations.  At December 31, 2019, we had accrued $108.4 million as a provision for environmental and asset retirement obligations. We cannot assure you that we have accurately estimated these obligations, and in the future our accrual could materially change. Our environmental and asset retirement obligations could have a material adverse impact on our cash flows, results of operations, or financial condition. For information on our potential environmental liabilities and asset retirement obligations, see Note 4 and Note 7 of Notes to Consolidated Financial Statements.

State ballot initiatives could impact our operations.

In recent years there have been several proposed or implemented ballot initiatives that sought to directly or indirectly curtail or eliminate mining in certain states, including Alaska, where our Greens Creek mine operates, and Montana, where we are seeking to develop the Montanore and Rock Creek projects. While both a salmon initiative in Alaska and a water treatment initiative in Montana were defeated by voters in November 2018, in the future similar or other initiatives that could impact our operations may be on the ballot in these states or other jurisdictions (including local or international) in which we currently or may in the future operate. To the extent any such initiative was passed and became law, there could be a material adverse impact on our financial condition, results of operations or cash flows.

Legal challenges could prevent the Rock Creek or Montanore projects from ever being developed.

The proposed development of our Rock Creek project has been challenged by several regional and national conservation groups at various times since the U.S. Forest Service (“USFS”) issued its initial Record of Decision (“ROD”) in 2003 approving Revett Mining Company’s plan of operation (Revett is now our wholly-owned subsidiary, named Hecla Montana, Inc.). Some of these challenges have alleged violations of a variety of federal and state laws and regulations pertaining to water rights and permitting activities at Rock Creek, including the Endangered Species Act, the National Environmental Policy Act (“NEPA”), the 1872 Mining Law, the Federal Land Policy Management Act, the Wilderness Act, the National Forest Management Act, the Clean Water Act, the Clean Air Act, the Forest Service Organic Act of 1897, and the Administrative Procedure Act. As a result of litigation challenging the ROD, in May 2010, the USFS was directed by the Montana Federal District Court to produce a Supplemental Environmental Impact Statement (“SEIS”) to address NEPA procedural deficiencies that were identified by the court.  The new SEIS was prepared and in August 2018, a new final ROD was issued. In early 2019, a group of environmental groups and other organizations filed a lawsuit challenging the ROD.   We cannot predict how any future challenges will be resolved or if they will continue to delay the planned development at Rock Creek. Even if the ROD is successfully defended, we would still be required to comply with a number of requirements and conditions as Rock Creek development progresses, failing which could make us unable to continue with development activities.

A joint final Environmental Impact Statement with respect to our Montanore project was issued in December 2015 by the USFS and Montana Department of Environmental Quality("DEQ"), and each agency issued a ROD in February 2016 providing approval for development of the Montanore project. However, private conservation groups have taken and may in the future take actions to oppose or delay the Montanore project. On May 30, 2017, the Montana Federal District Court issued Opinions and Orders in three lawsuits challenging previously granted environmental approvals for the Montanore project. The Orders overturned the approvals for the project granted by the USFS and the United States Fish and Wildlife Service, and in each case remanded the ROD and associated planning documents for further review by the agencies consistent with the Court’s Opinions. In June 2017, the Court vacated the agencies’ approvals for the project. As a result, additional work must be performed by the agencies to address the deficiencies in the ROD and associated planning documents identified by the Court, and new approvals must be granted, before the project may proceed beyond certain preliminary actions. In addition, the validity of Montanore’s water discharge permit under Montana law is pending before the Montana Supreme Court after it was vacated by a state court in July 2019. In the meantime, the site is operating under the previously issued permit as authorized by law.

In March 2018, each of Hecla Mining Company and our CEO was notified by the DEQ of alleged violations of Montana’s mine reclamation statutes and related regulations due to our CEO having been an officer of a mining company that declared bankruptcy in 1998, together with the fact that subsequently, proceeds from that company’s sureties were insufficient to fully fund reclamation at that company’s mine sites in Montana. To date, no action has been taken to revoke or deny any permits held by our subsidiaries, however, those subsidiaries have commenced litigation challenging the DEQ’s assertion. The DEQ in turn has initiated litigation against Hecla Mining Company and our CEO in an effort to halt the development of the Montanore and Rock Creek projects. It is possible that the litigation may be resolved unfavorably, which could have the effect of delaying, increasing the costs of, or preventing exploration and development efforts at the two projects.

We face risks relating to transporting our products, as well as transporting employees and materials at Greens Creek.

Certain of the products we ship to our customers are subject to regulatory requirements regarding shipping, packaging, and handling of products that may be considered dangerous to human health or the environment. Although we believe we are currently in compliance with all material regulations applicable to shipping, packaging, and handling our products, the chemical properties of our products or existing regulations could change and cause us to fall out of compliance or force us to incur substantial additional expenditures to maintain compliance with applicable regulations. Further, we do not ship our own products but instead rely on third party carriers to ship our products to our customers. To the extent that any of our carriers are unable or unwilling to ship our products in accordance with applicable regulations, including because of difficulty in obtaining, or increased cost of, insurance, or are involved in accidents during transit, we could be forced to find alternative shipping arrangements, assuming such alternatives would be available, and we could face liability as a result of any accident. Any such changes to our current shipping arrangements or accidents involving the shipment of our products could have a material adverse impact on our operations and financial results.

In addition, Greens Creek operates on an island and is substantially dependent on various forms of marine transportation for the transportation of employees and materials to the mine and for the export of its products from the mine. Any disruption to these forms of marine transportation could adversely impact mine operations, and possible effects could include suspension of operations.

The titles to some of our properties may be defective or challenged.

Unpatented mining claims constitute a significant portion of our undeveloped property holdings in the United States. For our operations in Canada and Mexico, we hold mining claims, mineral concession titles and mining leases that are obtained and held in accordance with the laws of the respective countries, which provide Hecla the right to exploit and explore the properties. The validity of the claims, concessions and leases could be uncertain and may be contested. Although we have conducted title reviews of our property holdings, title review does not necessarily preclude third parties (including governments) from challenging our title. In accordance with mining industry practice, we do not generally obtain title opinions until we decide to develop a property. Therefore, while we have attempted to acquire satisfactory title to our undeveloped properties, some titles may be defective.

Risks Relating to Our Common Stock and Our Indebtedness

The price of our stock has a history of volatility and could decline in the future.

Shares of our common and outstanding preferred stock are listed on the New York Stock Exchange (“NYSE”). The market price for our stock has been volatile, often based on:

The market price of our stock at any given point in time may not accurately reflect our value, and may prevent stockholders from realizing a profit on, or recovering, their investment.

Our Series B preferred stock has a liquidation preference of $50 per share or $7.9 million.

If we were liquidated, holders of our preferred stock would be entitled to receive approximately $7.9 million (plus any accrued and unpaid dividends) from any liquidation proceeds before holders of our common stock would be entitled to receive any proceeds, but after holders of all notes issued under the indenture governing our Senior Notes received any proceeds.

We may not be able to pay common or preferred stock dividends in the future.

Since January 2010, we have paid all regular quarterly dividends on our Series B preferred stock.  The annual dividend payable on the Series B preferred stock is currently $0.6 million. Prior to 2010, there were numerous occasions when we did not declare dividends on the Series B Preferred Stock, but instead deferred them. We cannot assure you that we will continue to pay preferred stock dividends in the future.

Our board of directors adopted a common stock dividend policy that has two components: (1) a dividend that links the amount of dividends on our common stock to our average quarterly realized silver price in the preceding quarter, and (2) a minimum annual dividend of $0.01 per share of common stock, in each case payable quarterly, when declared. See Note 9 of Notes to Consolidated Financial Statements for more information on our common stock dividend policy.

From the fourth quarter of 2011 through and including the fourth quarter of 2019, our board of directors has declared a common stock dividend under the policy described above (although in some cases only a minimum dividend was declared and none relating to the average realized price of silver due to the prices not meeting the policy threshold). The declaration and payment of common stock dividends, whether pursuant to the policy or in addition thereto, is at the sole discretion of our board of directors, and we cannot assure you that we will continue to declare and pay common stock dividends in the future. In addition, the indenture governing our Senior Notes limits our ability to pay dividends.

 Our existing stockholders are effectively subordinated to the holders of our Senior Notes.

In the event of our liquidation or dissolution, stockholders’ entitlement to share ratably in any distribution of our assets would be subordinated to the holders of our Senior Notes. Any rights that a stockholder may have in the event of bankruptcy, liquidation or a reorganization of us or any of our subsidiaries, and any consequent rights of stockholders to realize on the proceeds from the sale of any of our or our subsidiaries’ assets, will be effectively subordinated to the claims of the holders of our Senior Notes.

Additional issuances of equity securities by us would dilute the ownership of our existing stockholders and could reduce our earnings per share.

We may issue securities in the future in connection with raising capital, acquisitions, strategic transactions or for other purposes. To the extent we issue any additional equity securities (or securities convertible into equity), the ownership of our existing stockholders would be diluted and our earnings per share could be reduced.

The issuance of additional shares of our preferred or common stock in the future could adversely affect holders of common stock.

The market price of our common stock may be influenced by any preferred or common stock we may issue.  Our board of directors is authorized to issue additional classes or series of preferred stock without any action on the part of our stockholders.  This includes the power to set the terms of any such classes or series of preferred stock that may be issued, including voting rights, dividend rights and preferences over common stock with respect to dividends or upon the liquidation, dissolution or winding up of the business and other terms.  If we issue preferred stock in the future that has preference over our common stock with respect to the payment of dividends or upon liquidation, dissolution or winding up, or if we issue preferred stock with voting rights that dilute the voting power of our common stock, the rights of holders of the common stock or the market price of the common stock could be adversely affected.

If a large number of shares of our common stock are sold in the public market, the sales could reduce the trading price of our common stock and impede our ability to raise future capital.

We cannot predict what effect, if any, future issuances by us of our common stock or other equity will have on the market price of our common stock. Any shares that we may issue may not have any resale restrictions, and therefore could be immediately sold by the holders. The market price of our common stock could decline if certain large holders of our common stock, or recipients of our common stock, sell all or a significant portion of their shares of common stock or are perceived by the market as intending to sell these shares other than in an orderly manner. In addition, these sales could also impair our ability to raise capital through the sale of additional common stock in the capital markets.

The provisions in our certificate of incorporation, our by-laws and Delaware law could delay or deter tender offers or takeover attempts.

Certain provisions in our restated certificate of incorporation, our by-laws and Delaware law could make it more difficult for a third party to acquire control of us, even if that transaction could be beneficial to stockholders. These impediments include:

In addition, amendment of most of the provisions described above requires approval of at least 80% of the outstanding voting stock.

 If we cannot meet the NYSE’s continued listing requirements, the NYSE may delist our common stock.

Our common stock is currently listed on the NYSE. In the future, if we are not able to meet the continued listing requirements of the NYSE, which require, among other things, that the average closing price of our common stock be above $1.00 over 30 consecutive trading days, our common stock may be delisted. Our closing stock price on February 6, 2020 was $3.43.

If we are unable to satisfy the NYSE criteria for continued listing, our common stock would be subject to delisting. A delisting of our common stock could negatively impact us by, among other things, reducing the liquidity and market price of our common stock; reducing the number of investors willing to hold or acquire our common stock, which could negatively impact our ability to raise equity financing; decreasing the amount of news and analyst coverage of us; and limiting our ability to issue additional securities or obtain additional financing in the future.  In addition, delisting from the NYSE might negatively impact our reputation and, consequently, our business.

Any downgrade in the credit ratings assigned to us or our debt securities could increase future borrowing costs, adversely affect the availability of new financing and may result in increased collateral requirements under our existing surety bond portfolio.

As of February 6, 2020, our Senior Notes were rated "B-" with a negative outlook by Standard & Poor’s and "Caa1" with a stable outlook by Moody’s Investors Service. We cannot assure you that any rating currently assigned by Standard & Poor’s or Moody’s to us or our debt securities (including the Senior Notes) will remain unchanged for any given period of time or that a rating will not be lowered if, in that rating agency’s judgment, future circumstances relating to the basis of the rating so warrant. If we are unable to maintain our outstanding debt and financial ratios at levels acceptable to the credit rating agencies, or should our business prospects or financial results deteriorate, including as a result of declines in silver and gold prices or other factors beyond our control, our ratings could be downgraded by the rating agencies. Downgrading the credit rating of our debt securities or placing us on a watch list for possible future downgrading would likely adversely impact us, including our ability to obtain financing on favorable terms, if at all, increase borrowing costs, result in increased collateral requirements under our surety bond portfolio, and have an adverse effect on the market price of our securities, including our Senior Notes.

Our Senior Notes and the guarantees thereof are effectively subordinated to any of our and our guarantors’ secured indebtedness to the extent of the value of the collateral securing that indebtedness.

Our Senior Notes and the guarantees thereof are not secured by any of our assets or the assets of our subsidiaries. The indenture governing the Senior Notes permits us to incur secured debt up to specified limits. As a result, the Senior Notes and the guarantees thereof are effectively subordinated to our and our subsidiary guarantors’ future secured indebtedness with respect to the collateral that secures such indebtedness, including any borrowings under our revolving credit facility. Upon a default in payment on, or the acceleration of, any of our secured indebtedness, or in the event of a bankruptcy, insolvency, liquidation, dissolution, reorganization or other insolvency proceeding involving us or such guarantor, the proceeds from the sale of collateral securing any secured indebtedness will be available to pay obligations on the Senior Notes only after such secured indebtedness has been paid in full. As a result, the holders of the Senior Notes may receive less, ratably, than the holders of secured debt in the event of a bankruptcy, insolvency, liquidation, dissolution, reorganization or other insolvency proceeding involving us or such guarantor.

Any draw-downs on our $250 million revolving credit facility would be secured debt. We did not have a balance drawn on the revolving credit facility as of December 31, 2019, but utilized $33.6 million of the facility with letters of credit. See the risk factor above “We are required to obtain governmental permits and other approvals in order to conduct mining operations” for more information.

The terms of our debt impose restrictions on our operations.

The indenture governing our Senior Notes includes several significant covenants. These covenants could adversely affect us by limiting our ability to plan for or react to market conditions or to meet our capital needs. These covenants, among other things:

These restrictions may affect our ability to grow in accordance with our strategy. Further, our financial results, our substantial indebtedness and our credit ratings could adversely affect the availability and terms of any financing.

In addition, our revolving credit facility requires us to comply with various covenants, including certain financial ratios, that restrict management’s discretion to operate our business in certain circumstances. For example, these restrictions include limitations that could affect our ability to incur additional indebtedness, place liens or mortgages on our assets, sell assets or release collateral. These restrictions could make it more difficult for us to obtain additional financing or take advantage of business opportunities. Furthermore, a breach of any of these covenants could result in an event of default under the agreement governing our revolving credit facility that, if not cured or waived, could give the holders of the defaulted debt the right to terminate commitments to lend and cause all amounts outstanding with respect to the debt to be due and payable immediately. Acceleration of any of our debt could result in cross-defaults under our other debt instruments, including the indenture governing our Senior Notes, as well as certain forward sales contracts which may be outstanding from time to time. Our assets and cash flow may be insufficient to repay borrowings fully under all of our outstanding debt instruments if any of our debt instruments are accelerated upon an event of default, which could force us into bankruptcy or liquidation. In such an event, we may be unable to repay our debt obligations. In addition, in some instances, this would create an event of default under the indenture governing our Senior Notes.

Our Senior Notes are structurally subordinated to all liabilities of our non-guarantor subsidiaries.

The Senior Notes are structurally subordinated to the indebtedness and other liabilities of our subsidiaries that are not guaranteeing the Senior Notes, which include certain of our non-domestic subsidiaries and certain other subsidiaries. These non-guarantor subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any amounts due pursuant to the Senior Notes, or to make any funds available therefor, whether by dividends, loans, distributions or other payments. Any right that we or the guarantors have to receive any assets of any of the non-guarantor subsidiaries upon the liquidation or reorganization of those subsidiaries, and the consequent rights of holders of the Senior Notes to realize proceeds from the sale of any of those subsidiaries’ assets, will be effectively subordinated to the claims of those subsidiaries’ creditors, including trade creditors and holders of preferred equity interests of those subsidiaries. Accordingly, in the event of a bankruptcy, liquidation or reorganization of any of our non-guarantor subsidiaries, these non-guarantor subsidiaries will pay the holders of their debts, holders of preferred equity interests and their trade creditors before they will be able to distribute any of their assets to us or any guarantor. Unless they are guarantors of the Senior Notes or our other indebtedness, our subsidiaries do not have any obligation to pay amounts due on the Senior Notes or our other indebtedness or to make funds available for that purpose.

For the year ended December 31, 2019, our non-guarantor subsidiaries represented 8% of our sales of metals and 7% of our operating expenses. As of December 31, 2019, our non-guarantor subsidiaries represented 5% of our total assets and 2% of our total liabilities, including trade payables, deferred tax liabilities and royalty obligations.

Our variable rate indebtedness subjects us to interest rate risk, which could cause our indebtedness service obligations to increase significantly.

Borrowings under our credit facility are at variable rates of interest and expose us to interest rate risk. If interest rates increase, our debt service obligations on the variable rate indebtedness would increase even though the amount borrowed remained the same, and our net income and cash flows, including cash available for servicing our indebtedness, would correspondingly decrease. Assuming all revolving loans currently available to us were fully drawn, each one percentage point change in interest rates would result in a $1.2 million change in annual cash interest expense on our credit facility.

Key terms of the Senior Notes will be suspended if the Senior Notes achieve investment grade ratings and no default or event of default has occurred and is continuing.

Many of the covenants in the indenture governing the Senior Notes will be suspended if the Senior Notes are rated investment grade by Standard & Poor’s and Moody’s provided at such time no default or event of default has occurred and is continuing, including those covenants that restrict, among other things, our ability to pay dividends, incur debt and to enter into certain other transactions. We cannot assure you that the Senior Notes will ever be rated investment grade. However, suspension of these covenants would allow us to engage in certain transactions that would not be permitted while these covenants were in force, and the effects of any such transactions will be permitted to remain in place even if the Senior Notes are subsequently downgraded below investment grade.

We may be unable to repurchase Senior Notes in the event of a change of control as required by the indenture.

Upon the occurrence of certain kinds of change of control events specified in the indenture, holders of the Senior Notes will have the right to require us to repurchase all of the Senior Notes at a repurchase price equal to 101% of their principal amount, plus accrued and unpaid interest, if any, to the date of repurchase. Any change of control also would constitute a default under our revolving credit facility. Therefore, upon the occurrence of a change of control, the lenders under our revolving credit facility would have the right to accelerate their loans and, if so accelerated, we would be required to repay all of our outstanding obligations under such facility. We may not be able to pay the Senior Note holders the required price for their notes at that time because we may not have available funds to pay the repurchase price. In addition, the terms of other existing or future debt may prevent us from paying the Senior Note holders. We cannot assure you that we would be able to repay such other debt or obtain consents from the holders of such other debt to repurchase the Senior Notes. Any requirement to offer to purchase any outstanding Senior Notes may result in us having to refinance our outstanding indebtedness, which we may not be able to do. In addition, even if we were able to refinance our outstanding indebtedness, such financing may be on terms unfavorable to us.

Holders of the Senior Notes may not be able to determine when a change of control giving rise to their right to have the Senior Notes repurchased has occurred following a sale of “substantially all” of our assets.

The definition of change of control in the indenture governing the Senior Notes includes a phrase relating to the sale of “all or substantially all” of our assets. There is no precise established definition of the phrase “substantially all” under applicable law. Accordingly, the ability of a holder of Senior Notes to require us to repurchase its notes as a result of a sale of less than all our assets to another person may be uncertain.

Federal and state fraudulent transfer laws may permit a court to void the Senior Notes or any of the guarantees thereof, and if that occurs, holders of the Senior Notes may not receive any payments on the notes.

Federal and state fraudulent transfer and conveyance statutes may apply to the issuance of the Senior Notes and the incurrence of any guarantees of the Senior Notes. Under federal bankruptcy law and comparable provisions of state fraudulent transfer or conveyance laws, which may vary from state to state, the Senior Notes or any guarantees thereof could be voided as a fraudulent transfer or conveyance if we or any existing or future subsidiary guarantors, as applicable, (a) issued the Senior Notes or incurred such guarantee with the intent of hindering, delaying or defrauding creditors or (b) received less than reasonably equivalent value or fair consideration in return for either issuing the Senior Notes or incurring the guarantee and, in the case of (b) only, one of the following is also true at the time thereof:

As a general matter, value is given for a transfer or an obligation if, in exchange for the transfer or obligation, property is transferred or a valid antecedent debt is satisfied. A court would likely find that any subsidiary guarantor did not receive reasonably equivalent value or fair consideration for its guarantee to the extent such subsidiary guarantor did not obtain a reasonably equivalent benefit from the issuance of the Senior Notes.

We cannot be certain as to the standards a court would use to determine whether or not we or any subsidiary guarantor was insolvent at the relevant time or, regardless of the standard that a court uses, whether the Senior Notes or any guarantees would be subordinated to our or any subsidiary guarantor’s other debt. In general, however, a court would deem an entity insolvent if:

The subsidiary guarantees contain a “savings clause” intended to limit the subsidiary guarantor’s liability to the maximum amount that it could incur without causing the incurrence of obligations under its subsidiary guarantee to be a fraudulent transfer. This provision may not be effective to protect any subsidiary guarantees from being avoided under fraudulent transfer law. Furthermore, in Official Committee of Unsecured Creditors of TOUSA, Inc. v Citicorp North America, Inc., the U.S. Bankruptcy Court in the Southern District of Florida held that a savings clause similar to the savings clause used in the indenture was unenforceable. As a result, the subsidiary guarantees in that case were found to be fraudulent conveyances. The United States Court of Appeals for the Eleventh Circuit affirmed the liability findings of the Bankruptcy Court without ruling directly on the enforceability of savings clauses generally. If the TOUSA decision were followed by other courts, the risk that the guarantees would be deemed fraudulent conveyances would be significantly increased.

To the extent that any subsidiary guarantee is avoided, then, as to that subsidiary, the guaranty would not be enforceable.

If a court were to find that the issuance of the Senior Notes or the incurrence of any guarantee was a fraudulent transfer or conveyance, the court could (1) void the payment obligations under the Senior Notes or such guarantee, (2) subordinate the Senior Notes or such guarantee to presently existing and future indebtedness of ours or of the related subsidiary guarantor or (3) require the holders of the Senior Notes to repay any amounts received with respect to such guarantee. In the event of a finding that a fraudulent transfer or conveyance occurred, holders of the Senior Notes may not receive any repayment on the Senior Notes. Further, the avoidance of the Senior Notes could result in an event of default with respect to our and our subsidiaries’ other debt that could result in acceleration of that debt.

Finally, as a court of equity, a bankruptcy court could subordinate the claims in respect of the Senior Notes to other claims against us under the principle of equitable subordination if the court determines that (1) the holders of the Senior Notes engaged in some type of inequitable conduct, (2) the inequitable conduct resulted in injury to our other creditors or conferred an unfair advantage upon the holders of the Senior Notes and (3) equitable subordination is not inconsistent with the provisions of the Bankruptcy Code.

OPERATING PROPERTIES

The Greens Creek Unit

Various of our subsidiaries collectively own 100% of the Greens Creek mine, located on Admiralty Island near Juneau in southeast Alaska. Admiralty Island is accessed by boat, float plane, or helicopter. On the island, the mine site and various surface facilities are accessed by 13 miles of all-weather gravel roads. The Greens Creek mine has been in production since 1989, with a temporary care and maintenance period from April 1993 through July 1996.  Since the start of production, Greens Creek has been owned and operated through various joint venture arrangements.  For approximately 15 years prior to April 16, 2008, our wholly-owned subsidiary, Hecla Alaska LLC, owned an undivided 29.7% joint venture interest in the assets of Greens Creek.  On April 16, 2008, we completed the acquisition of all of the equity of two Rio Tinto subsidiaries holding a combined 70.3% joint venture interest in the Greens Creek mine, and which previously operated the mine, for approximately $758.5 million.  The acquisition of these two joint venture participants gave us control of 100% of the joint venture that owns and operates the Greens Creek mine.

The Greens Creek orebody contains silver, zinc, gold and lead, and lies within the Admiralty Island National Monument, an environmentally sensitive area. The Greens Creek property includes 440 unpatented lode mining claims, 58 unpatented millsite claims, 17 patented lode claims and one patented millsite. In addition, the Greens Creek site includes properties under lease from the U.S. Forest Service ("USFS") for a road right-of-way, mine portal and mill site access, camp site, mine waste area and tailings impoundment. The USFS leases have varying expiration terms. Greens Creek also has title to mineral rights on 7,301 acres of federal land acquired through a land exchange with the USFS. We are currently exploring, but not mining, on such federal land. The claims and leases above comprise a total area of approximately 24 square miles.

The project consists of the mine, an ore concentrating mill, a tailings impoundment area, a ship-loading facility, camp facilities, a ferry dock, and other related infrastructure.  The map below illustrates the location and access to Greens Creek:

The Greens Creek deposit is a polymetallic, stratiform, massive sulfide deposit. The host rock consists of predominantly marine sedimentary, and mafic to ultramafic volcanic and plutonic rocks, which have been subjected to multiple periods of deformation. These deformational episodes have imposed intense tectonic fabrics on the rocks. Mineralization occurs most often along the contact between a structural hanging wall of quartz mica carbonate phyllites and a structural footwall of graphitic and calcareous argillite. Major sulfide minerals are pyrite, sphalerite, galena, and tetrahedrite/tennanite.

Pursuant to a 1996 land exchange agreement, the joint venture owning Greens Creek transferred private property equal to a value of $1.0 million to the USFS and received exploration and mining rights to approximately 7,300 acres of land with mining potential surrounding the existing mine. Any production from new ore discoveries on the exchanged lands will be subject to a federal royalty included in the land exchange agreement. The royalty is only due on any production from reserves that are not part of Greens Creek’s extralateral rights. Thus far, there has been no production triggering payment of the royalty. The royalty is 3% if the average value of the ore during a year is greater than approximately $161 per ton at December 31, 2019.

Greens Creek is an underground mine accessed by a ramp from surface which produces approximately 2,300 tons of ore per day. The primary mining methods are cut and fill and longhole stoping. The Greens Creek ore processing facility includes a SAG/ball mill grinding circuit to grind the run of mine ore to liberate the minerals and produce a slurry suitable for differential flotation of mineral concentrates.  A gravity circuit recovers free gold that exists as electrum, a gold/silver alloy in the ore.  Gravity concentrates are produced from this circuit prior to flotation.  Three flotation concentrates are produced: a lead concentrate which contains most of the silver recovered; a zinc concentrate which is low in precious metals content; and a zinc-rich bulk concentrate that contains gold, silver, zinc, and lead and must be marketed to a smelter utilizing an Imperial Smelting Furnace (ISF) which can simultaneously produce both zinc and lead.  Doré is produced from the gravity concentrate by a third-party processor and further refined and sold to precious metal traders. The concentrate products are sold to a number of smelters and traders worldwide.  See Note 11 of Notes to Consolidated Financial Statements for information on the significant customers for Greens Creek’s products. Concentrates are shipped from the Hawk Inlet marine terminal about nine miles from the mill.

In 2019, ore was processed at an average rate of approximately 2,318 tons per day and total mill recovery was approximately 80% for silver, 90% for zinc, 82% for lead and 69% for gold.  The processing facility was originally constructed in 1988, with the first production commencing in 1989. Various modifications and upgrades have been made since that time.  Changes to the flotation circuit have included:  installation of regrind mills in 1992; mill recommissioning in 1996; expansion of concentrate cleaning equipment in 2000 and 2001; addition of a swing cell option in 2004, allowing for a reduction in bulk concentrate production; addition of an on-stream analyzer in 2006; expansion of lead rougher equipment in 2007; retrofit of two column sparge systems in 2010 and 2011; replacement of the carbon flotation columns complete with sparger upgrades in 2012 and 2013; installation of a replacement on-stream analyzer with an additional multiplexer in 2013 and 2014; and replacement of the sulfuric acid system with a carbon dioxide system for pH control in 2015.  Significant changes to the grinding circuit since original construction have included a new motor, two stage screening, and various internal lining modifications for the SAG mill, and replacement of the primary cyclones and the addition of a trommel magnet in the ball mill. In 2017, the swing cells were replaced with Woodgrove staged flotation reactor cells.

Electricity for the Greens Creek unit is provided through the purchase of surplus hydroelectric power from Alaska Electric Light and Power Company (“AEL&P”), to the extent it is available after the power needs of Juneau and the surrounding area are met. When weather conditions are not favorable to maintain lake water levels sufficient for all of the power needs at Greens Creek to be met by available hydroelectric power, the mine relies on power provided by on-site diesel generators, which can supply the full electrical load of the operation.

The employees at Greens Creek are employees of Hecla Greens Creek Mining Company, our wholly-owned subsidiary, and are not represented by a bargaining agent. There were 443 employees at the Greens Creek unit at December 31, 2019.

Definition drilling in 2019 focused on upgrading mineralized material at the 200 South, Northwest West, Southwest, East Ore, and 9A zones. After applying economic analysis to these drilling results, we believe this mineralized material will likely be converted into reserves in the future, primarily in the East Ore, 9A, 200 South, and Northwest West zones. Ore tonnage as well as silver and gold ounces and tons of zinc and lead in the reserve experienced a notable increase in 2019 resulting primarily from high-grade definition and exploration drilling results, new density measurements, new resource modeling techniques, and various design changes made to reduce dilution. Underground exploration activities at Greens Creek in 2019 continued to define new mineralization along trend of the 200 South Zone, extending the upper zone 350 feet to the south and the lower zone 800 feet to the south.

Planned activities to potentially add reserves in 2020 include additional drilling of the East Ore, West, 9A, Upper Plate, Southwest, Northwest West, 200 South and 5250 zones. Exploration targets in 2020 are expected to include the 200 South, Northwest West and the Deep Southwest zones. Development is planned in 2020 for a major new exploration drift which we believe will enable definition of targets in the deepest areas of the 200 South Zone.

As of December 31, 2019, we have recorded a $44.7 million asset retirement obligation for reclamation and closure costs. We maintained an $88.1 million reclamation and long-term water treatment bond for Greens Creek as of December 31, 2019.  The net book value of the Greens Creek unit property and its associated plant, equipment and mineral interests was approximately $593.1 million as of December 31, 2019.

Based on current estimates of reserves and mineralized material, the currently expected remaining mine life at Greens Creek is approximately 11 years. Information with respect to production, Cost of sales and other direct production costs and depreciation, depletion and amortization, average Cash Cost, After By-product Credits, Per Silver Ounce, All-In Sustaining Costs ("AISC"), After By-product Credits, Per Silver Ounce, and proven and probable ore reserves is set forth in the following table.

The Lucky Friday Unit

Since 1958, we have owned and operated the Lucky Friday mine, a deep underground silver, lead and zinc mine located in the Coeur d’Alene Mining District in northern Idaho. Lucky Friday is one-quarter mile east of Mullan, Idaho, and is adjacent to U.S. Interstate 90. The mine site and various surface facilities are accessed by paved roads from U.S. Interstate 90.  The Lucky Friday mine is comprised of 710 acres of patented mining claims and fee lands and 535 acres of unpatented mining claims. We also own or control approximately 26 square miles of mineral interests, which include patented mining and millsite claims, fee lands, and unpatented mining claims, that are adjacent to the Lucky Friday mine property. Below is a map illustrating the location and access to the Lucky Friday unit:

There have been two ore-bearing structures mined at the Lucky Friday unit.  The first, mined through 2001, was the Lucky Friday Vein, a fissure vein typical of many in the Coeur d’Alene Mining District. The ore body is located in the Revett Formation, which is known to provide excellent host rocks for a number of ore bodies in the Coeur d’Alene Mining District. The Lucky Friday Vein strikes northeasterly and dips steeply to the south with an average width of six to seven feet. Its principal ore minerals are galena and tetrahedrite with minor amounts of sphalerite and chalcopyrite. The ore occurs as a single continuous ore body in and along the Lucky Friday Vein. The major part of the ore body has extended from 1,200 feet to 6,020 feet below surface.

The second ore-bearing structure, known as the Lucky Friday Expansion Area, or Gold Hunter, has been mined since 1997 pursuant to an operating agreement with Silver Hunter Mining Company (“Silver Hunter”), our wholly owned subsidiary.  During 1991, we discovered several mineralized structures containing high-grade silver ores in an area known as the Gold Hunter property, approximately 5,000 feet northwest of the then existing Lucky Friday workings. This discovery led to the development of the Gold Hunter property on the 4900 level. At approximately 4,900 feet below surface, the Gold Hunter Veins are hosted in a 200-foot thick siliceous lens within the Wallace Formation that transitions to the St. Regis Formation below 5,900 feet. We are currently mining at approximately 6,300 feet below surface. The veins are sub-parallel and are numbered consecutively from the hanging-wall of the favorable horizon to the footwall. The strike of the vein system is west-northwest with a dip of 85 degrees to the south. The strike length of the mineralized package is approximately 2,150 feet. The 30 Vein, which contains higher silver grades, represents approximately 65% of our current proven and probable ore reserve tonnages, while the remaining 35% of our reserves are contained in various intermediate veins having lower silver grades than 30 Vein. The width of 30 Vein ranges from approximately 0.5 feet to 15.4 feet, with an average width of approximately 7.4 feet. While the veins share many characteristics with the Lucky Friday Vein, the Gold Hunter area possesses some mineralogical and rock mechanics differences that make it more favorable to mine at this time. On November 6, 2008, we, through Silver Hunter, completed the acquisition of substantially all the assets of Independence Lead Mines Company, which held an interest in the Gold Hunter property. The acquisition included all future interests or royalty obligations to Independence and the mining claims pertaining to the operating agreement with Hecla Limited that was assigned to Silver Hunter.

The principal mining method at the Lucky Friday unit is ramp access, underhand cut and fill. This method utilizes rubber-tired equipment to access the veins through ramps developed outside of the ore body. Once a cut is taken along the strike of the vein, it is backfilled with cemented tailings and the next cut is accessed below from the ramp system.

In 2017, we began work with a third-party equipment manufacturer to develop a remote vein miner ("RVM"), a disc-cutting, continuous-mining machine that we believe could be used for both ramp development and ore mining without use of drill and blast methods.  We conducted engineering of the machine and ordered long-lead components for the first RVM in late 2017, and manufacturing and engineering work continued on the machine in 2018 and 2019, with fabrication completed in 2019. Testing and modification of the RVM at the manufacturer's facilities is ongoing, and delivery to Lucky Friday is expected in 2020.

As discussed further below, the unionized employees at Lucky Friday were on strike from mid-March 2017 until early January 2020, resulting in limited production during that time. The mill has operated intermittently during the strike period, and total mill recovery was approximately 94% for silver, 91% for lead and 85% for zinc during 2019. Ore at the Lucky Friday is processed using a conventional lead/zinc flotation flowsheet, with process control guided by a real-time, on-line analyzer.  Run of mine ore is crushed in a conventional three stage crushing plant consisting of a primary jaw crusher, and a secondary crushing circuit, and tertiary cone crushing stage.  Crushed ore is ground in a ball mill, and the ground slurry reports to the lead flotation circuit.  The lead circuit tailings report to the zinc flotation circuit.  Lead and zinc concentrates are thickened and filtered, and final concentrate products are shipped to smelters for final processing.  The original flotation mill was constructed in 1960 and had a capacity of 750 tons per day. Various modifications and upgrades have been made since that time, including: installation of a 1,000 ton coarse ore bin and replacement of the ball mill in 1984 to increase processing capacity to 1,000 tons per day; replacement of the double-deck crushing screen with a triple-deck screen, installation of a tertiary cone crushing stage, lead concentrate flash flotation equipment, four ball mill cyclones, a mill feed sampler, and lead concentrate column cleaners and thickeners in 2005; addition of dust collection equipment in the crushing plant in 2006; installation of zinc concentrate flash flotation, conditioning, and column cleaner equipment, and an on-stream analyzer in 2007; construction of two new water treatment plants in 2008, with ongoing enhancements to those facilities since that time; addition of a discharge event pond in 2009; sand cyclone and reagent equipment in 2011; a disc filter added at Water Treatment Plant 04-3 in 2016; and various other mill refurbishments. Current processing capacity of the Lucky Friday facility is approximately 1,000 tons per day. All lead and zinc concentrate sales during 2019 were shipped to Teck Resources Limited's smelter in Trail, British Columbia, Canada.

During 2008, we initiated engineering, procurement and development activities relating to construction of #4 Shaft, which was completed in January 2017. The #4 Shaft provides access from the 4900 level down to the 8300 level, with a total shaft depth of 8620 feet. Completion of #4 Shaft and associated development allows us to mine mineralized material below our current workings and provide deeper platforms for exploration.

During 2014, Lucky Friday continued implementation of an Environmental Management System and completed installation of remote stream gauging stations. These stations assist in performing daily monitoring activities in nearby receiving waters as required by our effluent discharge permit. Additionally, we have completed reclamation activities on the 36 acre MTIS 4 borrow site and have achieved final stabilization of the disturbed area.  In 2015, closure plans and costs were updated and developed for MTIS 3 and 4.  The closure cost for MTIS 3 is based on the closure design and cost estimate developed by a third-party firm in conjunction with cost estimates prepared by Lucky Friday personnel to complete necessary associated work to facilitate the closure of the impoundment. The closure cost for MTIS 4 is based on the most recent closure cap design and was prepared for us by a consultant. At December 31, 2019, an asset retirement obligation of approximately $10.5 million had been recorded for closure of MTIS 3 and 4, reclamation and closure of the mine and mill upon the end of the known mine life based on the current plan, and ongoing monitoring and maintenance.

The net book value of the Lucky Friday unit property and its associated plant, equipment and mineral interests was approximately $437.7 million as of December 31, 2019. The age of the facilities at Lucky Friday ranges from the 1950s to 2019.

At December 31, 2019, there were 271 employees at Lucky Friday. The United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial, and Service Workers International Union is the bargaining agent for Lucky Friday’s 199 hourly employees, and 188 of the hourly employees were on strike as of December 31, 2019. Upon expiration of the prior collective bargaining agreement and after voting against our new contract offer at the time, the unionized employees went on strike on March 13, 2017. They remained on strike until January 7, 2020, when the union ratified a new collective bargaining agreement. The current labor agreement expires on January 6, 2023. Production at Lucky Friday was suspended from the start of the strike until limited production by salaried personnel commenced in July 2017. We expect re-staffing of the mine, which has commenced, to be completed in stages, with a return to full production by the end of 2020.

Avista Corporation supplies electrical power to the Lucky Friday unit.

There was no exploration or definition drilling during 2018 and 2019 due to the strike. In 2020, definition drilling is expected to resume near the 6350-52 Ramp West, 6500 East Lateral, and 6500 Far East to test the 30 Vein and a portion of the 30 Vein offset by the Silver Fault. Drilling is also expected to refine the intermediate vein package at the 6500 level and upgrade 30 Vein resources on the eastern end of the deposit. These adjacent veins are roughly defined as intermediate veins which have become an increasingly significant component, approximately 23%, of the mine’s production mix within the current life of mine plan. Exploration may resume on the far-east end of the Lucky Friday Extension deposit. The goal of this exploration drilling is to define vein extensions for the 30 Vein and intermediate veins.

Based on current estimates of reserves and mineralized material, the currently expected mine life at Lucky Friday is approximately 18 years. Information with respect to the Lucky Friday unit’s production, Cost of sales and other direct production costs and depreciation, depletion and amortization, average Cash Cost, After By-product Credits, Per Silver Ounce, AISC, After By-product Credits, Per Silver Ounce, and proven and probable ore reserves for the past three years is set forth in the table below.

The Casa Berardi Unit

In 2013, as a result of our acquisition of Aurizon Mines Ltd. ("Aurizon"), we acquired the Casa Berardi mine, located 95 kilometers north of La Sarre in the Abitibi Region of northwestern Quebec, Canada. The mining site is reached via a 38 kilometer all season gravel road which connects with the provincial and national paved roads grid. The property borders Ontario to the west and covers parts of Casa Berardi, Dieppe, Raymond, D'Estrees, and Puiseaux townships. The project area extends east-west for more than 37 kilometers and reaches 3.5 kilometers north-south. The Casa Berardi mine gold deposits are located along a 5 kilometer east-west mineralized corridor.

Aurizon acquired the claims, leases and infrastructure comprising the Casa Berardi mine project in 1998 from TVX Gold Inc. Aurizon engaged in exploration programs beginning in 1998, and production began in late 2006.

The nearest commercial airport to the Casa Berardi mine is located at Rouyn-Noranda. La Sarre can be reached from Rouyn-Noranda via provincial roads 101 and 111. The 38 kilometer all-season gravel road to the mine site branches off from the paved Route des Conquérants road, which runs north from its intersection with road 393 north of La Sarre and passes through the village of Villebois. The branch is approximately 21 kilometers north of Villebois. A gravel road links the East Mine and the West Mine (which roughly represent the east-west boundaries of the mining lease), and a number of forestry roads provide access to the rest of the project area, from east and west.

Hecla Quebec Inc., Hecla’s wholly owned subsidiary, owns a 100% interest in the mineral titles and mining leases comprising the current Casa Berardi mine. The Casa Berardi mine is composed of 69 contiguous claims, covering 3,148.3 hectares (7,779.6 acres) and two mining leases covering 481.4 hectares (1,189.7 acres).  The total area of the Casa Berardi property is 3,629.75 hectares (8,969.3 acres).  All the claims and leases are in good standing. We own an additional approximately 45 square miles of exploration property located adjacent to the current Casa Berardi mine and comprised of approximately 230 claims, most of which are subject to a 1% NSR royalty in favor of Lake Shore Gold Corp.

We also hold a non-exclusive lease BNE 25938 for a sand and gravel pit, tailings lease 70218, and an additional 12 acres of land contiguous to mining lease BM 768 for rock waste material storage.

Under the Quebec Mining Act, claims are required to be renewed every two years. Statutorily prescribed minimum work commitments apply to all claims and leases. As of December 31, 2019, the claims and leases comprising part of the Casa Berardi mine have excess work credits of CAD$12.5 million. Claims and leases for our other projects in Quebec have excess work credits of CAD$28.2 million as of December 31, 2019.

The operation consists of an underground mine and the East Mine Crown Pillar open pit mine. The underground mine has two shafts; the West Mine shaft reaching a vertical depth of 1096 meters, and the unused East Mine shaft located 4.3 kilometers to the east, and going down to a vertical depth of 379 meters. A system of declines and drifts connecting both shafts provide access and underground services to ore zones. The surface infrastructures include a cyanidation processing mill (carbon-in-leach), tailings impoundment areas, and other facilities and infrastructures. Power supply to the site is provided by a 55 kilometer, 120kV power line from the Hydro-Québec transformation station located in the town of Normétal. The map below illustrates the location and access to Casa Berardi:

Prior to Aurizon’s ownership, the Casa Berardi underground mine operated from 1988 to 1997, producing approximately 3.9 million tons of ore at an average gold grade of 0.2 ounces per ton from two sites, the West Mine and the East Mine. Aurizon’s operations from 2006 to 2012 produced approximately 4.5 million tons of ore at an average gold grade of 0.3 ounces per ton. A total of 1,625,500 ounces of gold were recovered by the previous operators prior to 2013. The mineral deposits cover a strike length of more than 5 kilometers.

The Casa Berardi mine is located in the northern part of the Abitibi sub-province, a subdivision of the Superior province, within the Canadian Shield. The Casa Berardi area belongs to the Harricana-Turgeon Belt, which is a part of the North Volcanic Zone. The regional geology is characterized by a mixed assemblage of mafic volcanics, flysch-type sedimentary iron formations, and graphitic mudrocks that are limited by a large granodioritic to granitic batholith. Structurally, the area is enclosed in the Casa Berardi Tectonic Zone, a 15-kilometer wide corridor that can be traced over 200 kilometers. A network of east-west to east-southeast and west-northwest ductile high strain zones mainly follows the lithological contacts.

Casa Berardi can be classified as an Archean sedimentary-hosted orogenic gold deposit. Mineralization is found in large low-sulphide quartz veins developed against the Casa Berardi fault, and in disseminated sulfides and stockworks lenses associated with strongly carbonate-sericite altered ductile deformation zones obliquely oriented to the Casa Berardi fault, and extending a few hundred meters on both sides of the fault following northwest and northeast orientations. Gold mineralization emplacement was coeval with the fault`s evolution and shows a strong structural control and vertical extension, even if other factors such as the nature of some host rocks and lithological contacts seem to have favored gold deposition.

The Casa Berardi Fault is defined by a stratigraphic contact between a graphite-rich sediment sequence at the base of the Taïbi domain, a northern continuous intermediary fragmental volcanic unit, and a southern polymictic conglomerate unit. The mineralization system is composed of large, low-sulfide quartz veins and low-grade stockworks and carbonate-mica replacement zones forming in the West Mine and Principal area. On the north side of the Fault, a thick sequence of very homogeneous wacke belonging to the Taïbi Group is affected by an amphibolites metamorphic grade. One kilometer further north is the easterly elongated Recher batholith, which is part of the northwestern boundary of the Abitibi greenstone belt.

Current reserves at the Casa Berardi mine comprise eight zones at the West Mine, spread over a moderate horizontal distance from each other and located at different mine elevations, plus open pit and underground areas at the East Mine.  The 113, Lower Inter, 118, 121, 123, 124 (Principal underground and open pit), 134, and the West Mine Crown Pillar ("WMCP") open pit zones in the West Mine, and the 148 Zone (open pit and underground) and the 160 open pit in the East Mine comprise the bulk of the reserve tonnage. The zones are of varying thickness, ranging from over 50 meters to less than three meters, which is the minimum mining width. Most of the hanging walls are sub-vertical (55º to 85º) and exhibit similar wall characteristics with the exception of the Lower Inter Zone, which in a number of places has relatively shallow hanging wall configurations (less than 45º).

The underground mine at Casa Berardi is a trackless mine accessed by declines and a shaft, which produces approximately 2,300 tons of ore per day. The mining methods are longhole transversal stoping in 10 meters or more mineralization width with good access from nearby development, and longitudinal retreat stoping in narrower ore bodies or long distances from development infrastructure. Longitudinal methods have the advantage of lower waste development requirements; however, there is much less flexibility in sequencing and in access, should ground instabilities occur. Timely supply of both cemented and unconsolidated backfill plays a crucial role in controlling dilution and maintaining a short stoping cycle. We believe this mining method satisfies all of the geotechnical requirements and constraints and, as a non-entry mining method, has proven to be safe and reliable in similar operations. The mineralized zones put in reserves are of varying thickness, ranging from a few tenths of meters to 3 meters, which is the minimum mining width. Most of the hanging walls are sub-vertical (55° to 85°), with typically the graphitic Casa Berardi fault at the footwall. Production from the underground mine areas is currently planned to continue for approximately 4.5 years, with the amount of material to be moved every six months to average between 270,000 and 410,000 tons, with variable quantities of waste.

In early 2016, we made the decision to construct the East Mine Crown Pillar ("EMCP") open pit, which is just west of the East Mine infrastructure. Stripping and development of the EMCP pit is planned to take place over five stages. The first stage was completed in the first half of 2016, and processing of ore from the EMCP pit began in July 2016. Stripping and development have been ongoing, and the pit is being expanded to the west and is currently in the final stage of development. The EMCP pit, including the extension area, uses conventional open pit mining methods, and is expected to run for an additional approximately 3 years of production. The average amount of material to be moved every six months is anticipated to be approximately 330,000 tons of ore, with variable quantities of waste.

With the addition of new information, including from new pits, evaluation of the schedule for mining the other pits is ongoing. The current plan is as follows:

The gold recovery process is based on carbon-in-leach ("CIL") technology where gold is dissolved in a cyanide solution, and precipitated on activated carbon grains put in suspension. The product is doré bars poured in the mill’s refinery. Construction of the processing facility, consisting of a 3,600-ton crushing, ore processing, and tailings facility, was completed in 1988 by Inco Gold and Golden Knight Resources Inc., and ore processing began in September 1989. During the next 9 years the mill processed 3.9 million tons at an average grade of 0.2 ounces per ton.  Production at Casa Berardi was suspended in 1997 and the mill was put on care and maintenance until 2005, when major rehabilitation work was initiated by Aurizon.  Beginning in the third quarter of 2005, upgrades including refurbishing of the crushing, grinding circuits, conveyors, and leach circuits, the addition of gravity circuits, and construction of an assay laboratory were performed, resulting in an increase of mill capacity.  The mill facility was commissioned in November of 2006 and the processing rate ramped up to reach commercial production in May of 2007. In 2019, total mill recovery of gold was approximately 81%.

The mine and mill complex are permitted to process 1,600,000 dry metric tonnes (approximately 1,764,000 tons) of ore per year. Difficult ground conditions and bottlenecks in stope preparation have limited underground production to levels below the designed capacity. In 2019, the mill processed approximately 1,378,065 tons, for an average of 3,775 tons per day. The current life of mine plan is based on an average milling rate near the permitted level, with the inclusion of material from the surface mines, for the remaining mine life.

Based on current estimates of reserves and mineralized material, the currently expected remaining mine life at Casa Berardi is approximately 15 years, and includes anticipated production from the underground mine areas, the EMCP pit, and the planned new pits discussed above.

In-stope and definition underground drilling during 2019 concentrated within the 113, 118, 119, 123, 124, 148, 152, and 160 zones to refine orebody shapes and gold grade distributions for mine planning and reserves. Underground exploration drilling of the 113, 118, and 128 zones in the West Mine identified mineralization down-plunge to the west and to the east. Drilling of the 148, 152, 157, and 160 zones in the East Mine identified high grade mineralization down plunge. Surface definition and exploration drilling continues to define limits for the WMCP and EMCP.

The currently contemplated underground in-stope and definition drilling programs for 2020 are expected to appraise the high-grade ore shoots of the 113, 118, 119, 123, 128, and 134 zones in the western part of the mine and high-grade extensions of the 148 Zone in the East Mine. Underground exploration drilling is currently expected to evaluate extensions of the 113, 118 and 128 zones in the western part of the mine and the 148 and 152 zones in the East Mine.

We expect the mine plan will be modified from time to time as new information is incorporated into the plan.

The employees at Casa Berardi are employees of Hecla Quebec Inc., our wholly-owned subsidiary, and are not represented by a bargaining agent. There were 624 employees at the Casa Berardi unit at December 31, 2019. We also utilize third-party contractors, which use their employees and equipment, for some of the mining activities at Casa Berardi.

Hecla acquired Aurizon on June 1, 2013 for approximately CAD$740.8 million (US$714.5 million), and has operated the Casa Berardi mine since the acquisition. The net book value of the Casa Berardi unit property and its associated plant, equipment and mineral interests was approximately $660.9 million as of December 31, 2019. As of December 31, 2019, we have recorded a $4.5 million asset retirement obligation for reclamation and closure costs. We maintain a surety bond as financial guarantee for future reclamation and closure work.

The San Sebastian Unit

The San Sebastian mine is located approximately 60 miles northeast of the city of Durango, Mexico, on concessions acquired in 1999. Access to San Sebastian is via Mexico highway 40, approximately 6 miles east of Guadalupe Victoria, and then approximately 15 miles of paved rural road through the towns of Ignacio Allende and Emiliano Zapata.

Our concession holdings cover approximately 160 square miles, including the Francine Vein, East Francine Vein, Middle Vein, North Vein, and the Andrea Vein and multiple outlying active exploration areas. Mineral concession titles are obtained and held under the laws of Mexico, and are valid for 50 years with the possibility of extending another 50 years. There are work assessment and tax requirements that are variable and increase with the time that the concession is held. The map below illustrates the location and access to San Sebastian:

Mineralization at the project occurs as low and intermediate sulfidation epithermal veins within the Saladillo valley area. Economically, the most important veins at the project have been the Francine, East Francine, Middle and North veins located at the north end of the Saladillo valley and the Andrea Vein located 4 miles to the south. The veins are hosted within a series of shales with interbedded fine-grained sandstones interpreted to belong to the Cretaceous Caracol Formation. Most of the veins strike to the west-northwest and vein dips vary from steep toward the west to shallow toward the east. True vein widths range from 5 to 30 feet, and the average true width of the veins in the district is 8 feet.

Mineralization occurs in an epithermal setting at various paleo-depths. High-grade gold and silver occur both in the very shallow environment in the upper 1,000 feet of the crust and in deep silver-gold-lead-zinc root zones of the system at depths between 2,000 and 3,500 feet below the paleo-water table. Hypogene minerals include sphalerite, galena, argentite, pyrite, chalcopyrite, native silver and gold in electrum. The veins are oxidized down to approximately 300 feet below surface and the oxidized portions of the veins contain limonite, hematite, silver halides and various copper carbonates. Matrix minerals include fine-grained to coarsely crystalline quartz bands and chlorite-quartz-adularia bands and late calcite fill. Mineralization within the vein structures is generally deposited in high-grade “shoots” bound both laterally and horizontally by sharp gradients in grade-thickness.

Hecla operated the San Sebastian underground mine from 2001 to 2005. The historical life-of-mine production from the Francine and Don Sergio veins over four years was 11.2 million ounces of silver and 155,937 ounces of gold. Access to both underground workings was through ramps from the surface connecting one or more levels. Ore was mined by the cut-and-fill stoping method and extracted from the stopes using rubber-tired equipment and hauled to the surface in trucks.

Exploration success on the Middle, North, and East Francine veins and completion of a Preliminary Economic Assessment lead to the decision in the third quarter of 2015 to develop shallow open pit mines on those veins, with development commencing in the fourth quarter of 2015. Ore production from the Middle and East Francine veins commenced late in the fourth quarter of 2015, and from the North Vein in the first quarter of 2016. Production from the original pits concluded in December 2017. The North Vein was expanded in 2018, and limited surface ore production resumed. The pits were extended to a maximum of approximately 270 feet in depth. Near-surface material is excavated, with drill and blast techniques used for deeper material. Production from the expanded North Vein pit started in January 2018 and is expected to end in the first quarter of 2020; 159,000 tons were mined from 2018 to 2019, and 16,000 tons are planned to be mined in 2020. Production is achieved through excavating and drilling and blasting the shallow-dipping, high-grade silver veins which carried significant gold credits. Third-party contractors are used for mining from the pits.

In January 2017, work commenced to build a new underground decline and rehabilitate historical underground workings at the San Sebastian mine in order to mine deeper ore from the Middle Vein. Underground production started in January 2018 and is planned to end in the third quarter of 2020; 173,000 tons were mined from 2018 to 2019, and 34,000 tons are planned to be mined in 2020. We plan to mine ore by the cut-and-fill stoping method and for the ore to be extracted from the stopes using rubber-tired equipment and hauled to the surface in trucks.

In mid-2018, we commenced development work to obtain a bulk sample from the Hugh Zone, which was discovered in 2005 and is the down-dip sulfide extension of the past-producing Francine vein. The Hugh Zone is an area containing polymetallic mineralized material located in the deeper portion of the previously mined Francine Vein. An area of polymetallic material has also been identified in the deeper portion of the western Middle Vein, which is located approximately 700 feet north of the Francine Vein. We believe mineralization in this area remains open laterally and at depth and this area represents an excellent exploration target for underground drilling in the future. In 2019 a ramp was driven to the polymetallic zone of the Francine Vein from a crosscut in the Middle Vein. Test mining of polymetallic mineralization was conducted for most of 2019, with the aim of developing this area toward larger scale production. We entered into a toll milling agreement with another company to process our sulfide ore at their flotation mill facility in Zacatecas, which is approximately 26 miles from the San Sebastian mine site. Processing of the bulk sample material commenced in 2019. If testing of the bulk sample is successful, we believe production from the Hugh Zone has the potential to extend the mine life at San Sebastian.

In late 2018 and early 2019, a new vein, called the El Toro Vein, was discovered approximately 1.3 miles south of the San Sebastian Mine Area under thick soil cover. Drilling throughout 2019 at the El Toro Vein area defined oxide mineralization over 1.3 miles of strike length and 900 feet downdip. In late 2019 infill drilling was conducted on key portions of the El Toro Vein and studies are in progress to assess the economic feasibility of developing this area toward production through a combination of surface and underground mining. With the recent El Toro discovery, we believe the combined strike length of the primary veins at the project (Francine, Andrea, Middle, North and El Toro) is over 6 miles.

Current run of mine ore is hauled in trucks by contractors to a processing facility near Velardeña, Durango, Mexico, which is located approximately 60 miles from the San Sebastian mine site. We previously owned the Velardeña mill, but now use it to process ore under a lease arrangement. Processing of ore averaged approximately 479 tons per day in 2019, with recovery of approximately 91% for silver and 85% for gold. As of December 31, 2019, we have the ability to lease the facility through 2020. The mill is a conventional leach, counter-current decantation and Merrill Crowe precipitation circuit capable of processing up to approximately 550 tons per day, depending on ore hardness. The ore is crushed in a two-staged crushing plant consisting of a primary jaw, a secondary cone crusher and a double-deck vibrating screen. The grinding circuit includes a primary ball mill and cyclone classifiers. The ground ore is thickened followed by agitated leaching and four stages of counter-current decantation to wash solubilized silver and gold from the pulp. The solution bearing silver and gold is clarified, deaerated, and zinc dust is added to precipitate silver and gold that is recovered in plate and frame filters. The precious metal precipitate is smelted and refined into doré, and is then shipped to a third-party refiner. Since construction of the mill in 1994, two leach tanks were added in 2001, a filter press was added in 2002, and the Merrill Crowe system and Autojet Filters were expanded and modified in 2012. In addition, rehabilitation of various components of the mill was completed in 2015 prior to the start of processing of the ore from the open pits.

At December 31, 2019, the net book value of the San Sebastian unit property and its associated plant and equipment was $10.8 million. Infrastructure includes the underground mine portal and development, a water supply system, maintenance shop, warehouse, laboratory, leased mill and related improvements, and various offices. Equipment and facilities are in good condition. As of December 31, 2019, $7.4 million has been accrued for reclamation and closure costs. All permits required for current mining of the open pits and the underground mine and operation of the mill are in place.

There was a total of 68 employees at the San Sebastian unit as of December 31, 2019, with most of them employed by our subsidiary that provides certain specialized services to another subsidiary that owns the mine. These employees are not represented by a bargaining agent. We currently primarily use third-party contractors for mining and operation of the processing facility. The hourly employees of the lessor of the processing facility are represented by the Sindicato Nacional de Trabajadores Mineros, Metalúrgicos, Siderúrgicos y Similares de la República Mexicana (a Mexico national union) as bargaining agent.

Based on current estimates of reserves and mineralized material, the currently expected remaining mine life at San Sebastian is approximately 9 months as of the date of filing this report.

Electric power is purchased from Comisiòn Federal de Electricidad (a Mexico federal electric company).

At San Sebastian, Short Vertical Reverse Circulation ("SVRC") drilling has proven to be an effective technique to explore for new veins under soil cover. The El Toro Vein was recently discovered through a combination of SVRC followed up with core drilling. In 2020, SVRC drilling is currently scheduled to continue to explore the soil covered area located south and west of the San Sebastian Mine area which we believe to be prospective. Several SVRC geochemistry anomalies were generated last year and new anomalies are expected to be generated 2020. These anomalies may represent new veins under cover and follow up core drilling is scheduled for 2020 to test these targets.

Information with respect to the San Sebastian unit’s production, Cost of sales and other direct production costs and depreciation, depletion and amortization, average Cash Cost, After By-Product Credits, Per Silver Ounce, AISC, After By-product Credits, Per Silver Ounce, and proven and probable ore reserves is set forth in the table below.

The Nevada Operations Unit

As a result of our acquisition of Klondex in July 2018, we obtained 100% ownership of the Fire Creek mine, Hollister mine, Midas mine and milling facility, and the Aurora mine and milling facility, and various other mineral interests comprising a total land position of approximately 110 square miles in northern Nevada.

The employees at the Nevada Operations unit are employees of Klondex Gold & Silver Mining Company, our wholly-owned subsidiary, and are not represented by a bargaining agent. There were 143 employees at the Nevada Operations unit at December 31, 2019.

As of December 31, 2019, the total net book value of the properties, plants, equipment and mineral interests at the Nevada Operations unit was approximately $511.4 million, consisting of the following (in millions):

Additional information on the Nevada Operations properties is below.

Fire Creek

In 1975, Klondex acquired the property as a very early stage exploration project. Fire Creek is located in north-central Nevada in Lander County, and to a lesser extent Eureka County, approximately 16 miles south of a major highway (Interstate 80) near other large gold deposits and mines which are owned and operated by major mining companies. Access to Fire Creek from Interstate 80 is by State Road 306, a good-quality road. Company-maintained mine and exploration roads provide access throughout the property. Fire Creek is a high-grade, epithermal vein deposit, and the land package covers approximately 18,755 acres (approximately 20.7 square miles), consisting of approximately 831 unpatented mining claims, and both leased and owned private fee lands. Our unpatented claims occupy public lands, administered by the United States Bureau of Land Management ("BLM"). Unpatented claims are governed by the laws and regulations of the U.S. federal government and the state of Nevada. Property fees are paid annually to the county in which they are held. To maintain our unpatented claims, we must file an annual notice of intent to maintain the claims within the county they are located and pay the annual mineral claim maintenance fees to the BLM. Certain of Fire Creek's claims are subject to various net smelter return ("NSR") royalties. Some of these royalties have been prepaid or advanced; however, those that have not been prepaid or advanced have no expiration date, and we may continue to incur payments on these royalties in the future. In addition, Fire Creek is subject to a 2.5% NSR royalty for all production commencing in 2019, and there is no expiration date on the royalty. Fire Creek consists of an underground, mechanized narrow vein mine, related mine support infrastructure, mining equipment, and administrative buildings, all of which are in operating condition. The map below illustrates the location and access to Fire Creek:

Mineralization at Fire Creek occurs in steeply dipping epithermal veins within Tertiary basalt flows and intrusive rocks. The mineralized basaltic rocks are a suite of mafic, extrusive rocks associated with the regional north-northwest-trending Northern Nevada Rift ("NNR") structural zone. The NNR system has been documented in multiple geophysical and geological studies and is distinguished as a linear magnetic anomaly approximately 30 miles wide that extends 190 miles south-southeast from the Oregon-Nevada border to central Nevada. The NNR originates from the McDermitt Caldera in northwest Nevada and is likely related to impingement of the Yellowstone hot-spot on continental crust.

The deposit is a low-sulfidation epithermal deposit vertically-zoned within high-angle northwest striking structures, hosted in a mid-Miocene basalt package. Mineralization occurs as shallow structurally-controlled fault hosted gold mineralization in variably altered Tertiary basalts and as native gold in steeply dipping quartz-calcite veins or structures. A package of middle Miocene basalt and basaltic andesite flow has been cut by high-angle normal faults related to both NNR and Basin and Range extension that form grabens and half-grabens which are the structural controls in the district.

High-grade mineralization has been delineated between approximately 4,900 feet and 5,700 feet and is open both up and down dip as well as along strike. Lower-grade mineralization occurs from the surface and mineralization is open at depth. Vein textures, gangue minerals, and alteration seen at Fire Creek are typical of low-sulfidation epithermal systems. Widespread propylitic alteration changes to argillic alteration proximal to veins and/or other structural fluid conduits. Low-grade gold mineralization is often spatially associated with the argillic alteration zone surrounding the high-grade gold. Mineralization often occurs along discrete horizons within vein structures. An opaline silica cap is discontinuously preserved at surface above the main mineralization at Fire Creek. Mineralized faults near this opaline silica were targeted by early prospecting and later shallow drilling by previous operators in the 1980s.

Fire Creek is defined by two major north-northwest striking vein arrays, each comprised of several en-echelon veins. Several new target areas outside of the known vein arrays have been defined by both gradient-array and dipole-dipole induced polarization surveys as well as versatile time domain electromagnetic system geophysical surveys.

The Fire Creek mine is a trackless mine accessed by a decline, and has historically produced approximately 350 tons of ore per day. The mining method is primarily longhole stoping, with ramp access utilized. Ore mined at Fire Creek is trucked approximately 165 miles to the Midas mill for processing, which is discussed in the Midas section below.

Fire Creek receives electrical power provided by NV Energy, a major Nevada power company.

As of December 31, 2019, we have recorded a $1.6 million asset retirement obligation for reclamation and closure costs at Fire Creek. We maintain a surety bond as financial security for future reclamation and closure work.

There is a lack of investment in mine development, including horizontal drifts ("Haulages") and the ramp or decline system ("Spirals"), at Fire Creek. As a result, there are not sufficient platforms to keep quality targets in the pipeline to replenish reserves as they are depleted. Because total production and capital costs had exceeded sales since acquisition, in the second quarter of 2019 we conducted a review of our Nevada operations which, among other changes, resulted in a plan to limit near-term mining at Fire Creek to areas where development has already been completed. As a result, we anticipate production at Fire Creek will continue until mid-2020, and then be suspended at that time as we continue studies of hydrology, mining and milling. See Item 1A. Risk Factors – Operation, Development, Exploration and Acquisition Risks – The issues we have faced and continue to face at our Nevada Operations unit could require us to write-down the associated long-lived assets. We could face similar issues at our other operations. Such write-downs may adversely affect our results of operations and financial condition.

In 2019, definition drilling at Fire Creek focused on the up and down extensions of known veins in the Spiral 2 and Spiral 4 areas. A small definition drilling program is planned for 2020 and is expected to focus on offsetting a high-grade drill intercept below Spiral 4.

At the Fire Creek mine, the 2020 exploration program is currently expected to be limited to detailed mapping, sampling and alteration mineral spectroscopy designed to evaluate vein targets within our extensive property.

Hollister

The Hollister property has been owned and operated since the 1900s by various mining companies which mined mercury in the early 1900s and gold and silver in the late part of the century. Klondex acquired the property in October 2016. Hollister is a fully-permitted past producing underground and open pit operation. It is located in north-central Nevada in Elko County, approximately 61.5 miles east-northeast of Winnemucca, Nevada and 17 miles southeast from the Midas mine. Hollister is accessed by all-weather paved and gravel county roads. Hollister is comprised of 1,005 unpatented lode claims and 11 unpatented mill site claims that cover an area in excess of 15,000 acres, and an additional 209 unpatented lode claims through agreements covering approximately 4,320 acres. Our unpatented claims occupy public lands administered by the BLM. Unpatented claims are governed by the laws and regulations of the U.S. federal government and the state of Nevada. To maintain our unpatented claims in good standing, we must file an annual notice of intent to maintain the claims with the county and pay the annual mineral claim filing fees to the BLM. Certain claims and areas of Hollister are subject to royalties, including seven separate NSR royalties ranging from 1% to 5%, and a 1% NSR royalty after 500,000 ounces of gold production occurring from October 3, 2016, when Klondex acquired the property. There is no expiration date on the aforementioned royalties. Hollister includes an underground mine, former open pit mines, related mine support infrastructure, mining equipment, and administrative buildings, all of which are in operating condition. The map below illustrates the location and access to Hollister:

The Hollister mine is located along the NNR, and is on trend with the north-western end of the Carlin Trend, which is approximately 5 miles wide and 40 miles long. Mineralization is related to the Miocene period of magmatic activity associated with the NNR while gold mineralization on the Carlin Trend has been dated to late Eocene/early Oligocene magmatism. Epithermal disseminated gold mineralization is hosted in volcanic tuffaceous units, andesites, and the Ordovician Vinini Formation. High-grade gold and silver mineralization is hosted as banded quartz veins in a group of near-vertical faults and fissures that trend west-northwest to east-west. The amount of displacement across these faults is small and their strike continuity varies between one hundred to several thousand feet. Primary lithologies in the area have been strongly altered by hydrothermal fluids with large areas of chalcedonic replacement bodies at the paleo water table in addition to sinter deposits.

The Hollister property also includes the Hatter Graben vein system, which is located approximately 2,500 feet east of the Hollister mine's underground development and has been down dropped approximately 800 feet lower than the current mine resource. The system of mineralized veins has a known vertical extent of 1,400 feet and strike length of 2,000 feet. This East-West trending zone is open along strike to the east and west and at depth and mineralization is strengthening in the east as historic high-grade intersections occur up to 4000 feet along strike to the east. Gold and silver mineralization is dominantly in the Ordovician quartzites, siltites and argillites. Higher grades are associated with banded quartz veins from inches to feet in width and extensive zones of quartz vein stockwork and quartz matrix breccias also contain significant mineralization. The first surface holes were initiated at Hatter Graben in the third quarter of 2018 with the intent to extend the current identified mineralized material east and west.  Drill holes at 300-foot intervals have intersected swarms with multiple veins and mineralized breccias at the anticipated distance.  Development of a drift from the Hollister mine's underground workings to the Hatter Graben area commenced in the third quarter of 2018.

The Hollister mine is a trackless mine accessed by a decline. Due to variability within the Hollister mine material, a selective mining approach is employed by matching mining methodology to stope characteristics. Hollister mining methods include cut and fill, ramp access and longhole stoping. The current Hollister mine plan primarily employs cut and fill stoping. As discussed below, ore mined at Hollister is trucked to the Midas mill for processing, and the resulting loaded carbon is stripped at the Aurora mill.

Hollister receives electrical power provided by NV Energy.

As of December 31, 2019, we have recorded a $3.0 million asset retirement obligation for reclamation and closure costs at Hollister. We maintain a surety bond as financial guarantee for future reclamation and closure work.

In 2019, definition drilling at Hollister focused on the extension of the West Gloria to the west and . two surface exploration holes to the east of the Hatter Graben resource.

At the Hollister mine, the 2020 exploration program is expected to consist primarily of detailed mapping, sampling and alteration mineral spectroscopy designed to evaluate vein targets within our extensive property. No underground or surface exploration drilling is planned in 2020 at Hollister.

As a result of our cessation of development in the second quarter of 2019, production at Hollister and development of the Hatter Graben project was suspended.

Midas

The Midas mining district has historic gold production dating as early as 1907. Since modern mining began in 1998, 2.2 million ounces of gold and 26.9 million ounces of silver have been produced by three previous owners prior to Klondex. Klondex acquired the fully-permitted Midas mine and ore milling facility in February 2014. Midas is located in north-central Nevada in Elko County and lies about 58 miles east of Winnemucca on Nevada State Highway 789, and one mile from the town of Midas, Nevada. Midas is a high-grade, epithermal vein deposit, and the land package covers approximately 30,000 acres (~47 square miles), which includes fee lands, federal unpatented mining claims, seven mining leases, BLM rights-of-way, general agreements, easements, and surface use agreements, with varied terms and annual payments. Within the land package, there are 1,489 federal unpatented mining claims, of which 1,456 are owned and 33 are leased. Owned and leased fee lands comprise approximately 2,985 acres of the land package which is a mix of surface-mineral rights and surface rights only. Our unpatented claims occupy public lands, administered by the BLM. Unpatented claims are governed by the laws and regulations of the U.S. federal government and the state of Nevada. Property fees on fee lands are paid annually to the county in which they are held. To maintain our unpatented claims, an annual notice of intent must be filed with the respective county, in addition to paying the annual mineral claim maintenance fees to the BLM. Certain of the Midas claims are subject to a royalty. Midas is also subject to a 2.5% NSR royalty from all production commencing in 2019, and there is no expiration date on the royalty. Midas includes an underground, mechanized narrow vein mine, related mine support infrastructure, mining equipment, a Merrill-Crowe refining facility, a milling circuit, and administrative buildings, all of which are in operating condition.

As of December 31, 2019, we have recorded a $16.6 million asset retirement obligation for reclamation and closure costs at Midas. We maintain a surety bond as financial security for future reclamation and closure work.

The map below illustrates the location and access to Midas:

The Midas mine is the largest known gold-silver epithermal deposit along the NNR, and is located in the Midas mining district, also known as the Gold Circle district. The Midas deposit consists of a series of complex steeply dipping, quartz-calcite-adularia precious metal veins hosted by volcanic and volcanoclastic rocks. Gold mineralization occurs as electrum and is intimately associated with selenide and sulfide minerals. It belongs to a suite of middle Miocene low-sulfidation epithermal gold and silver mineralizing systems associated with magmatism and faulting along the NNR. The mineralization model at Midas is a shallow, low-sulfidation, vertically- and laterally-zoned, epithermal gold-silver system. Rocks in the Midas district are primarily ash flow, air-fall and lithic tuffs, felsic plugs, volcanoclastic sediments and gabbroic sills and dikes.

Gold and silver mineralization at Midas is hosted in several northwest-striking veins. The veins are divided into four principal groups based on their location and orientation. The two principal groups that host the majority of the identified mineralized material are the Main Veins and East Veins. The Main Veins dip easterly and are gold dominant, while the East Veins dip to the west and contain higher silver content than the Main Veins. The Main Veins produced more than 2.2 million ounces of gold and 26.9 million ounces of silver between 1998 and 2013, principally from the Colorado Grande and Gold Crown Veins. Initial development and production from the East Veins began in 2012. The third group of veins is comprised of the Queen and Trinity Veins located to the south of the existing workings and south of the regional South Owyhee Fault. They are defined by limited underground and surface drilling and there has been no mine production from them to date. The Queen Vein and Trinity Vein systems represent high-priority, near-mine exploration targets. The fourth group of veins are west of the Main Vein system and includes the Link and Midas Trend Veins. Like the southern vein group, these veins have yet to be delineated from underground.

Mineralized material has been identified on the Main and East veins and other veins near the recently active mine workings. Active drill testing has recently taken place in these areas and has been prioritized based on ounce expectations, accessibility from existing development and geotechnical, ventilation, and hydrological considerations.

The Midas mine is located on the southeast flank of the Snowstorm Mountain range near the eastern margin of the NNR structural domain, hosted in a bimodal suite of volcanic rocks. Several other structurally controlled, epithermal precious-metal vein deposits are hosted in similar Miocene-age volcanic rocks along the NNR, including Fire Creek and the Mule Canyon mine. These mineral deposits occur along the NNR and share similar mineralization characteristics, including epithermal textures and trace-elements, locally high-grade gold and silver, mid-Miocene ages of mineralization and close temporal association with the Miocene host rocks.

The Midas mine is a modern, mechanized narrow vein mine. Design constraints included four feet minimum width for longhole stopes with development drifts spaced at 50-foot vertical intervals. Stope development drift dimensions maintained a constant height of 11 feet and a minimum width of seven feet. Cut and fill stopes are a minimum of six feet in width, and each cut is ten feet high. Mining and backfill tasks were created from all designed excavations. These tasks were assigned costs and productivities specific to the excavation or backfill task type. Alternative mining methods such as shrinkage stoping and alimak stoping may be investigated in the future. The veins at Midas can vary in thickness from a few inches to over ten feet. Production at the Midas mine was suspended in the fourth quarter of 2019.

Midas Mill

Ore from the Fire Creek, Midas and Hollister mines is processed at the Midas mill, which has a design capacity of 1,200 tons per day. Fire Creek and Midas ore was previously processed using a counter current decantation ("CCD") circuit, with Hollister ore processed using a CIL circuit. All ore has been processed using the CIL circuit since April 2019. Run-of-mine ore is crushed to 100% passing one-half inch in a conventional two-stage crushing circuit which utilizes a primary jaw crusher and a secondary cone crusher with the circuit closed by a double deck vibrating screen. The crushed product reports to the grinding circuit consisting of an 800 horsepower overflow ball mill and a 250 horsepower vert-mill. The circuit is closed using a bank of four (three operating, one standby) 10-inch cyclones. A portion of the cyclone underflow is sent to a gravity concentrator to remove coarse gold. The gravity concentrate is leached using an Acacia intense cyanidation unit with the gravity tail returned to the grinding circuit for further grinding. The ground product is thickened before being leached with cyanide for 72 hours in a series of eight leach tanks. Thickener underflow is pumped to the first in a series of four CIL tanks. The pregnant solution from the Acacia reactor also currently reports to the first CIL tank. Sodium cyanide is added to the first tank to enable gold leaching. Each of the four tanks are equipped with a carbon retention screen and a carbon advance pump. The first and fourth tanks also have a loaded carbon screen on the top of the tanks. The slurry flows through the retention screens to the next successive tank and is ultimately pumped to cyanide detoxification and to the tails facility. New carbon is added to the fourth tank and is pumped counter current to the slurry flow from the fourth tank, progressively upstream, until loaded carbon is pumped over the screen on the first tank and into carbon transport bags. The carbon transport bags are then loaded on a truck and shipped for sale to third-party processors, or hauled to the Aurora mill where they are stripped. The sludge from stripping at the Aurora mill is collected and shipped to the Midas refinery to be poured into doré bars. The bars are shipped off site for further refining by a third party.

When the CCD circuit is utilized for Fire Creek and Midas ore, the leached slurry from the leach tanks reports to a conventional five-stage counter current decantation circuit with the overflow solution from the first thickener, together with the pregnant solution from the Acacia reactor, reporting to the Merrill-Crowe circuit where zinc dust is used to precipitate the precious metal from solution. The underflow from the fifth thickener is treated to eliminate the remaining cyanide and pumped to the tailings storage facility. Mercury is removed from the precipitate in a retort oven before being smelted and poured into doré bars. The bars are shipped off site for further refining by a third party.

For 2019, total mill recovery of gold and silver was approximately 87% and 53%, respectively. The Midas mill processed ore at a steady rate during 2019. Batch processing of ore is planned until the suspension of production at Fire Creek anticipated in mid-2020, but third-party options are being evaluated.

Midas receives electrical power provided by NV Energy.

In 2019, surface exploration efforts focused on target definition within the district.

At the Midas mine, the 2020 exploration program is expected to consist primarily of detailed mapping, sampling and alteration mineral spectroscopy. No underground or surface exploration drilling is planned in 2020 at Midas.

Aurora

Gold was discovered in 1860 on the Aurora property and since that time various companies have mined from this location. Klondex acquired the property in October 2016. The Aurora project includes fully-permitted past producing underground mine and open pit mine operations, which are currently inactive. Aurora is located in west central Nevada 10 miles from the California border in Mineral County, approximately 20 miles west of Hawthorne, Nevada. Access is provided by all-weather paved and gravel county roads. Aurora consists of 92 patented mining claims, 944 acres of fee lands, and 448 unpatented lode-mining claims, totaling approximately 9,928 contiguous acres that encompass the entire district. Patented claims occupy private lands and our unpatented claims occupy public lands, administered by the BLM. Unpatented claims are governed by the laws and regulations of the U.S. federal government and the state of Nevada. To maintain our patented claims in good standing, we must pay the annual property fee payments to the county in which the claims are held. To maintain our unpatented claims in good standing, we must file an annual notice of intent to maintain the claims with the county and pay the annual mineral claim filing fees to the BLM. A portion of the patented and unpatented claims owned or leased by us and the leased fee lands are subject to underlying royalties, including a 3% royalty that would be split among two companies. Aurora includes an underground mine, former open pit mines, related mine support infrastructure, mining equipment, a milling circuit with permitted tails storage facility, and administrative buildings, all of which are in operating condition. The site has access to three-phase overland power which is used to operate the mill. The map below illustrates the location and access to Aurora:

Aurora is located within the Walker Lane structural belt of western Nevada. The Walker Lane is characterized by northwest-trending en echelon right-lateral strike slip faults that have tilted and rotated structural blocks since mid-Miocene through the Quaternary. Mineralized veins typically occur along northeasterly orientations. Northeast structures mostly host post-date vein mineralization in the district. Mineralization at Aurora occurs as low-sulfidation epithermal veins, breccias, and stockwork zones in Miocene intermediate to felsic composition volcanic rocks. The Prospectus and Humboldt areas are underlain by a complex series of andesitic flows, conglomerates, and lahars. The Martinez area is underlain by a more “porphyritic” volcanic/subvolcanic rock of andesitic to dacitic composition. Mineralized veins are typically composed of several generations of silica accompanied by variable amounts of adularia, sericite, pyrite, base metal sulfides, sulfosalts and electrum.

The Aurora mill is operational and has been used to strip loaded carbon from ore that has been processed at the Midas mill. The crushed product is ground using a SAG mill and two over flow ball mills with the circuit closed by a bank of cyclones. The cyclone overflow reports to a series of 8 CIL tanks where cyanide is added and precious metal is leached from the ore and adsorbed onto the carbon. Carbon bags are first emptied into an attrition tank. From the attrition tank the carbon is pumped over a dewatering screen, reporting to a carbon storage tank. From the carbon storage tank, the carbon is pumped over another dewatering screen, reporting to the acid wash vessel. The carbon is acid washed using dilute nitric acid to remove acid soluble scale from the carbon. After acid wash the carbon is pumped to the strip vessel where the precious metal is removed from the carbon. Hot caustic solution is pumped through the vessel to remove the precious metal from the carbon and into the pregnant strip solution tank. The strip solution is then pumped through a series of three electrowinning cells where the precious metal is removed from solution, reporting as sludge in the bottom of the cell. The sludge is collected into either buckets or bins and transported to the Midas refinery. Fluxes and sludge are added to the refinery furnace and poured into doré bars. The bars are transported to a third-party refinery for further processing.

As of December 31, 2019, we have recorded a $3.5 million asset retirement obligation for reclamation and closure costs at Aurora. We maintain a surety bond as financial security for future reclamation and closure work.

We plan to place the Aurora mill on care-and-maintenance in the first half of 2020.
