Item 4. Information on the Company

Cautionary Note to United States Investors

In Canada, an issuer is required to provide technical information with respect to mineralization, including reserves and resources, if any, on its mineral exploration properties in accordance with Canadian requirements, which differ significantly from the requirements of the SEC applicable to registration statements and reports filed by United States companies pursuant to the Securities Act, or the Exchange Act. As such, information contained in this annual report concerning descriptions of mineralization under Canadian standards may not be comparable to similar information made public by United States companies subject to the reporting and disclosure requirements of the SEC. In particular, this annual report on Form 20-F includes the terms “mineral resource,” “measured mineral resource,” “indicated mineral resource” and “inferred mineral resource”. Investors are advised that these terms are defined in and required to be disclosed under Canadian rules by National Instrument 43-101 (“NI 43-101”). U.S. Investors are cautioned not to assume that any part of the mineral deposits in these categories will ever be converted into reserves. However, these terms are not defined terms under SEC Industry Guide 7 and are not recognized in reports and registration statements filed with the SEC by U.S. domestic issuers. In addition, NI 43-101 permits disclosure of “contained ounces” of mineralization. In contrast, the SEC only permits issuers to report mineralization as in place tonnage and grade without reference to unit measures.

The definitions of proven and probable reserves used in NI 43-101 differ from the definitions in SEC Industry Guide 7. Under SEC Industry Guide 7 (under the Exchange Act), as interpreted by the staff of the SEC, mineralization may not be classified as a “reserve” for United States reporting purposes unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Among other things, all necessary permits would be required to be in hand or issuance imminent in order to classify mineralized material as reserves under the SEC standards.

United States investors are cautioned not to assume that any part or all of the mineral deposits identified as an “indicated mineral resource,” “measured mineral resource” or “inferred mineral resource” will ever be converted to reserves as defined in NI 43-101 or SEC Industry Guide 7. Further, “inferred mineral resources” have a great amount of uncertainty as to their existence and economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian securities legislation, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, but are used to form the basis of a preliminary economic assessment. U.S. investors are cautioned not to assume that part or all of an inferred mineral resource exists, or is economically or legally mineable.

A. History and development of the Company

The Company was incorporated by Memorandum of Association under the laws of the Province of British Columbia on May 15, 1968, and on August 22, 1969, by virtue of an amalgamation with Ace Mining Company Ltd., became a public company whose common shares are registered under the Exchange Act, changing its name to Avino Mines & Resources Limited. On April 12, 1995, the Company changed its corporate name to International Avino Mines Ltd. and effected a reverse stock split of one common share for every five common shares outstanding. On August 29, 1997, the Company changed its corporate name to Avino Silver & Gold Mines Ltd., its current name, to better reflect the business of the Company of exploring for and mining silver and gold. In January 2008, the Company announced the change of its financial year end from January 31 to December 31. The change was completed in order to align the Company’s financial statement reporting requirements with its Mexico subsidiaries which operate on a calendar fiscal year.

The Company is a reporting issuer in all of the Provinces of Canada, except for Quebec, a foreign private issuer with the SEC and is listed on the TSX Venture Exchange (Tier 1 status) under the symbol “ASM”, on the NYSE-MKT under the symbol “ASM”, and on the Berlin and Frankfurt Stock Exchanges under the symbol “GV6”. In September, 2013, the Company’s listing on the TSX Venture Exchange was reclassified from Tier 2 to Tier 1 status. The principal executive office of the Company is located at Suite 900, 570 Granville Street, Vancouver, British Columbia V6C 3P1, and its telephone number is 604-682-3701.

The Company is a natural resource company, primarily engaged in the extracting and processing of gold, silver, and copper and the acquisition and exploration of natural resource properties. The Company’s principal business activities have been the exploration for and extracting and processing of gold, silver, and copper at mineral properties located in the State of Durango, Mexico. The Company also owns other exploration and evaluation assets in British Columbia and the Yukon Territory, Canada.

B. Business overview

Operations and Principal Activities

The Company is a Canadian-based resource firm focused on silver, gold, and copper exploration, extraction and processing. The Company has a long prior history of operation, beginning in 1968 with the development of the Avino Silver Mine, located in the state of Durango, Mexico (the “Avino Mine”). From 1974 to 2001, the Avino Mine produced silver, gold, copper and lead and provided hundreds of jobs for the Durango region before closing due to depressed metal prices and closing of a smelter. Beginning in 2002, the Company re-directed its corporate strategy to focus almost entirely on silver, and began acquiring silver properties in North America. The Company acquired the Eagle property in Canada’s Yukon Territory and the Aumax silver and gold property in British Columbia. Each property produced encouraging assays for silver through drilling and sampling, however, in late April 2012, the Company relinquished its interest in the Aumax silver and gold property to focus on its property in Mexico. The Avino Mine in Mexico and surrounding mineral leases continue to hold silver potential. These properties, along with other silver and gold projects, will remain the Company’s principal focus for the foreseeable future.

Presently, the Company is an exploration-stage company pursuant to SEC Industry Guide 7 as it has not yet established mineral reserves. On October 1, 2012, the Company declared that extracting and processing resources at levels intended by management had been achieved at the San Gonzalo Mine. The decision was based on the following criteria:

The above factors were considered in making the decision that extracting and processing resources at levels intended by management had been achieved as at October 1, 2012, and management is confident that its decision is appropriate and accurately reflects the stage the Company is in.

In the second quarter of 2016, the Company declared that effective April 1, 2016 extracting and processing resources at levels intended by management had been achieved at the Avino Mine following an advancement and test period of 19 months. The decision was based on the following criteria:

The above factors were considered in making the decision that extracting and processing resources at levels intended by management had been achieved as at April 1, 2016, and management is confident that its decision is appropriate and accurately reflects the stage the Company is in.

In August 2014, Avino and Bralorne Gold Mines Ltd. (“Bralorne”) entered into a binding arrangement agreement, whereby Avino would acquire all of the outstanding common shares of Bralorne, which Avino did not already own, by way of a plan of arrangement under the Business Corporations Act (British Columbia). Bralorne holds an undivided 100% interest in the Bralorne Mine project in British Columbia.

On July 8, 2014, Avino acquired a 33.33% interest in Bralorne from an unrelated party on the open market for cash consideration of $2,660,000 in connection with its intention to acquire all of the outstanding common shares of Bralorne. With the acceptance of the TSX-V, Avino also made a $1,250,000 loan to Bralorne (in three tranches) to provide immediate working capital. The loan carried interest at 12% per annum, and the principal amount and accrued interest were secured by a general security agreement against all of the assets of Bralorne. On October 20, 2014, under the plan of arrangement, Bralorne shareholders received 2,636,845 common shares of Avino, resulting in Bralorne becoming a wholly-owned subsidiary of Avino. All unexercised outstanding stock options of Bralorne were cancelled, and Bralorne’s common shares were delisted from the TSX Venture Exchange and the OTCQX.

Avino’s remaining Mexican properties other than San Gonzalo and Avino as well as its Canadian properties are all in the exploration stage. In order to determine if a commercially viable mineral deposit exists in any of these properties, further geological work will need to be done, and based upon the results of that work a final evaluation will need to be made to conclude on economic and legal feasibility. The Company is currently focusing on extracting and processing resources at the San Gonzalo Mine and the Avino Mine, exploration of the Avino property in Mexico and the Bralorne Mine project in British Columbia, Canada. The Company's other Canadian properties are not deemed to be material and are subject to care and maintenance for further exploration and evaluation, if any.

Competition

The mining industry in which the Company is engaged is highly competitive. Competitors include well-capitalized mining companies, independent mining companies and other companies having financial and other resources far greater than those of the Company. The Company competes with other mining companies in connection with the acquisition of gold, silver and other base metal properties. In general, properties with a higher grade of recoverable minerals and/or which are more readily mined afford the owners a competitive advantage in that the cost of production of the final mineral product is lower.

Seasonality

Certain of our operations are conducted in British Columbia and the Yukon Territory. The weather during the colder seasons in these areas can be extreme and can cause interruptions or delays in our operations. As a result, the preferable time for activities in these regions is the spring and summer when costs are more reasonable and access to the properties is easier. In the summer months, however, if the weather has been unusually hot and dry, access to the Company’s properties may be limited as a result of access restrictions being imposed to monitor the risks of forest fires.

Governmental Regulation

The current and anticipated future operations of the Company, including exploration and evaluation activities and extracting and processing resources on its properties, require permits from various federal, territorial and local governmental authorities and such operations are and will be governed by laws and regulations governing prospecting, development, mining, production, exports, taxes, labor standards, occupational health, waste disposal, toxic substances, land use, environmental protection, mine safety and other matters. Companies engaged in the development and operation of mines and related facilities generally experience increased costs and delays in production and other schedules as a result of the need to comply with applicable laws, regulations and permits. Such operations and exploration activities are also subject to substantial regulation under these laws by governmental agencies and may require that the Company obtain permits from various governmental agencies. The Company believes it is in substantial compliance with all material laws and regulations which currently apply to its activities. There can be no assurance, however, that all permits which the Company may require for construction of mining facilities and conduct of mining activities will be obtainable on reasonable terms or that such laws and regulations, or that new legislation or modifications to existing legislation, would not have an adverse effect on any exploration or mining project which the Company might undertake.

The Company believes it has obtained all necessary permits and authorizations required for its current exploration and mining activities. The Company has had no material costs related to compliance and/or permits in recent years, and anticipates incurring necessary expenditures to maintain compliance in the future. Unfavorable amendments to current laws, regulations and permits governing operations and activities of resource exploration companies, or more stringent implementation thereof, could have a materially adverse impact on the Company and cause increases in capital expenditures which could result in a cessation of operations by the Company.

Failure to comply with applicable laws, regulations and permitting requirements may result in enforcement actions thereunder, including orders issued by regulatory or judicial authorities causing operations to cease or be curtailed, and may include corrective measures requiring capital expenditures, installation of additional equipment or remedial actions. Parties engaged in exploration and mining activities may be required to compensate those suffering loss or damage by reason of the mining activities and may have civil or criminal fines or penalties imposed for violation of applicable laws or regulations.

The enactment of new laws or amendments to current laws, regulations and permits governing operations and activities of mining companies, or more stringent implementation thereof, could have a material adverse impact on the Company and cause increases in capital expenditures or costs of extracting and processing resources or reductions in levels of extracting and processing resources at its mining properties or require abandonment or delays in the exploration and evaluation of new mining properties.

Governmental Regulation - Mexico

Mineral exploration and mining in Mexico is covered under the Mining Law as first published in June 1992, and most recently amended in August 2014. Mining activities in Mexico are administered by the Ministry of Economy. Environmental regulations are covered under “Ley General del Equilibrio Ecológio y la Protección al Ambiente” (General Law of Ecological Balance and Environmental Protection) and its regulations. Certain other environmental laws, including “Ley de Aguas Nacionales” (Law of National Waters) and “Ley Forestal” (Forestry Law) and their associated regulations may also cover certain operations. The kind of permits or authorizations required to conduct mining or mineral exploration operations in Mexico depend upon the type of operation. Common exploration activities do not require prior environmental authorization or licenses, but it is advisable to request a confirmation from the National Water Commission that planned operations will not affect the water table. It is also necessary to confirm that any planned operations will not be conducted in protected natural areas.

Governmental Regulation - British Columbia

The Bralorne Mine holds a Mining Permit under the Mining Act of British Columbia as administered by the Ministry of Energy and Mines. The Permit M-207 is currently under a Permit Amendment process to update the Permit for production including the incorporation of the updated Interim Closure and Reclamation Plan. A Draft Permit Amendment has been issued by the Ministry of Energy and Mines for review by Ministry of Environment (British Columbia) and the First Nations.

The Bralorne Mine would be subject to the Metal Mining and Effluent Regulations under the Fisheries Act as administered by Department of Fisheries and Oceans Canada for effluent flowrate of greater than 50m3/day. Current final discharge flowrates from the TSF seepages are less than this flowrate. The Bralorne Mine holds an emission and an effluent Permit under the Ministry of Environment (British Columbia). Both environmental Permits are current. Bralorne Mines has applied for a Permit amendment for expanded water treatment under the effluent Permit 14480. The Permit amendment is underway.

Mining activities in British Columbia are subject to the Mines Act and the Health, Safety and Reclamation Code (the “Code”), which are administered by the Minister of Energy and Mines, and in particular its Mines and Minerals Resource Division, as well as the Chief Inspector of Mines. Mining permits are issued upon meeting certain conditions, including the provision of a reclamation bond, and mining activities are regularly inspected for compliance with the Code.

C. Organizational structure

The Company’s Mexican subsidiaries are the wholly owned subsidiary Oniva Silver and Gold Mines S.A. de C.V., referred to as “Oniva”, Promotora, in which the Company has direct ownership of 79.09%, and Avino Mexico in which the Company has a 98.45% direct ownership and an additional 1.22% indirect ownership held through Promotora. The Company’s total effective ownership interest in Avino Mexico is 99.67%. All of these subsidiaries are incorporated under the laws of Mexico. The Company also owns 100% of Bralorne Gold Mines Ltd., incorporated in British Columbia, Canada.

D. Property, plant and equipment

The Company is extracting resources and processing it to yield a bulk silver/gold concentrate at the San Gonzalo Mine and a copper concentrate from the Avino Mine, both of which are located on the Avino property in Durango, Mexico. The Company is also exploring options to re-process a large tailings resource left from past mining on the Avino property. In addition, the Company is exploring four silver and gold projects in Canada. All of the Company’s mineral property interests in Canada are wholly-owned by the Company. In Mexico, the Company has a 99.67% interest in Avino Mexico, a Mexican company which is involved in the mining of commercial resources and resource exploration and evaluation, including the operation of the Avino and San Gonzalo Mines. The Company owns and manages its Canadian properties. Exploration in Canada is focused on the Bralorne Mine project in southwest British Columbia which was acquired by the Company in 2014. The Bralorne Mine project is considered in the advanced exploration phase and extracting and processing resources at trial levels took place between 2011 and 2014. In addition to the Bralorne Mine project, Avino has in recent years conducted limited prospecting, trenching and drill programs on the Eagle, Olympic-Kelvin, and Minto properties.

The Company uses detailed sampling to provide the basis for quality estimates and grades of its mineral discoveries. Samples are collected under the supervision of a qualified person who then follows procedures for the collection, sample preparation and chain of custody guidelines for the shipment of the samples to a certified commercial laboratory as set out in National Instrument 43-101. These commercial labs have standard Quality Assurance/Quality Control protocols in place for the various assaying methods that are being used on the samples. In addition, blanks, standards and duplicates are generally used to confirm the validity of the results before they are reported.

Avino Property, Durango, Mexico

Location

The property is located in Durango State in North Central Mexico, within the Sierra Madre Silver Belt on the eastern edge of the Sierra Madre Occidental mountain range. The nearest major center is the city of Durango, 82 km to the southwest of the property. The property is within the municipality of Pánuco de Coronado between the towns of Pánuco de Coronado and San José de Avino. The property is located at latitude N 24° 53’, longitude W 104° 31’, 14 km northwest of Highway 40D.

The property is situated as illustrated in the figures below:

General Property Location Map

Regional Property Location Map

Accessibility and Local Resources

The property is accessible by road and is an important part of the local community from which skilled workers are available. Access is provided by Highway 40, a four-lane highway leading from Durango, past the airport and on to the city of Torreon in Coahuila. Successive turn-offs for the property are at Francisco I Madero, Ignacio Zaragoza, and San José de Avino (Slim 2005d). The Avino mineral concessions are covered by a network of dirt roads which provide easy transport access between all areas of interest on the Property and the mill at the main Avino Mine (Gunning 2009).

The nearest major city is Durango, with a population of approximately 600 thousand. Durango is a major mining center in Mexico where experienced labour and services can be obtained. The two towns nearest the mine are Pánuco de Coronado and San José de Avino, where the majority of the employees live while working at the mine. Pánuco de Coronado has a population of approximately 12,000, and San José de Avino is a small center with a population of less than 1,000.

Geology and Mineralization

The property is located within the Sierra de Gamon, on the east flank of the Sierra Madre Occidental. The area is a geological window into the Lower Volcanic series and consists mainly of volcanic flows, sills, and tuffaceous layers of andesite, rhyolite, and trachyte. Individual rock units vary from 300 to 800 m in thickness. Andesitic rocks outcrop over most of the region with other rock types occurring more sparsely to the north (Slim, 2005d).

A large monzonitic intrusion is observed in the region in the form of dykes and small stocks, which appear to be linked to the onset of the Avino vein mineralization. Other post-mineralization dykes of intermediate to felsic composition outcrop in various areas and appear to cause minor structural displacements. Several mafic sills are also found in various parts of the region and are related to recent volcanism.

Regionally, the Avino concession is situated within a 12 km north-south by 8.5 km caldera, which hosts numerous low sulphidation epithermal veins, breccias, stockwork and silicified zones. These zones grade into a “near porphyry” environment, particularly in the Avino Mine area. The caldera has been uplifted by regional north trending block faulting (a graben structure), exposing a window of andesitic pyroclastic rocks of the lower volcanic sequence, a favourable host rock, within the caldera. This sequence is overlain by rhyolite to trachytes with extensive ignimbrite layers forming the upper volcanic sequence and is intruded by monzonite bodies. The basal andesite-bearing conglomerate and underlying Paleozoic basement sedimentary rocks (consisting of shales, sandstones and conglomerates) have been identified on the Avino concession in the south-central portion of the caldera, covering the Guadalupe, Santiago, San Jorge, the San Gonzalo Trend, Malinche, Porterito and Yolanda areas. A northerly trending felsic dyke, probably a feeder to the upper volcanic sequence, transects the Property and many of the veins. The Aguila Mexicana low temperature vein system, with significant widths but overall low precious metal values, trends north-northwest, similar to the felsic dyke and with similar continuity across the property. The two structures may occupy deep crustal faults that controlled volcanism and mineralization, with the felsic dyke structure controlling the emplacement of the Avino, Nuestra Senora and El Fuerte-Potosina volcanic centres and the Aguila Mexicana controlling the Cerro San Jose and El Fuerte-Potosina volcanic centres (Paulter 2006).

Silver- and gold-bearing veins cross-cut the various lithologies, and are generally oriented north-northwest to south-southeast and northwest to southeast. The rocks have been weathered and leached in the upper sections, as a result of contact with atmospheric waters. The oxide tailings material is primarily from this source, whereas the sulphide tailings are predominantly from material sourced at depth from the underground workings. In Mexico, these types of deposits can have large lateral extents, but can be limited in the vertical continuity of grades.

The valuable minerals found during the period of mining of the oxide zone were reported to be argentite, bromargyrite, chalcopyrite, chalcocite, galena, sphalerite, bornite, native silver, gold and native copper. The gangue minerals include hematite, chlorite, quartz, barite, pyrite, arsenopyrite and pyrrhotite. Malachite, anglesite, and limonite are common in the quartz zones of the weathered parts of the oxide material.

Property Ownership

The current Property is comprised of 23 mineral concessions, totalling 1,103.934 ha.

In 1968, Avino Mines and Resources Ltd. acquired a 49% interest in Avino Mexico and Minera San José de Avino SA, which together held mineral claims totalling 2,626 ha (6,488 ac). Avino Mines and Resources Ltd. retained Vancouver-based Cannon-Hicks & Associates Ltd. (Cannon-Hicks), a mining consulting firm, to conduct the exploration and development of the Property. Cannon-Hicks exploration activities included surface and underground sampling and diamond drilling (VSE 1979).

In early 1970, Avino Mines and Resources Ltd. signed a letter of intent with Denison Mines Ltd. for the future development of the Avino Mine. However, a formal agreement was never signed.

In May 1970, Avino Mines and Resources Ltd. signed a formal agreement with Selco Mining and Development (Selco), a division of Selection Trust Company. Due to other commitments, Selco abandoned its interest in the Project in 1973 (VSE 1979). 

In October 1973, Avino Mines and Resources Ltd. signed a new agreement with S.G.L. Ltd. and Sheridan Geophysics Ltd. Under the terms of the agreement, S.G.L. Ltd. was to provide up to $500,000 plus the management to erect a resource processing plant. The agreement provided for the return of the capital from first cash flow, plus a management fee and interest payment together with an option to convert a portion of the advanced funds to common shares. The agreement with S.G.L. Ltd. was terminated in mid-1976.

On July 17, 2006, the Company completed the acquisition of Compañía Minera Mexicana de Avino, S.A. de C.V. (“Avino Mexico”), a Mexican corporation, through the acquisition of an additional 39.25% interest in Avino Mexico, which combined with the Company’s pre-existing 49% share of Avino Mexico, brought the Company’s ownership interest in Avino Mexico to 88.25%. The additional 39.25% interest in Avino Mexico was obtained through the acquisition of 79.09% of the common shares of Promotora Avino S.A. de C.V., referred to as “Promotora”, which in turn owns 49.75% of Avino Mexico’s common shares, and the direct acquisition of 1% of the common shares of Avino Mexico.

The July 17, 2006, acquisition was accomplished by a share exchange by which the Company issued 3,164,702 shares as consideration, which we refer to as the “Payment Shares”, for the purchase of the additional 39.25% interest in Avino Mexico. The Payment Shares were valued based on the July 17, 2006 closing market price of the Company’s shares on the TSX-V.

The Company acquired a further 1.1% interest in Avino Mexico through the acquisition from an estate subject to approval and transfer of the shares to the Company by the trustee for the estate. On December 21, 2007, approval was received and the Company obtained the 1.1% interest from the estate for no additional consideration.

On February 16, 2009, the Company converted existing loans advanced to Avino Mexico into new additional shares of Avino Mexico. As a result, the Company’s ownership interest in Avino Mexico increased to 99.28%.

On June 4, 2013, the Company converted existing loans advanced to Avino Mexico into new additional shares of Avino Mexico, resulting in the Company’s ownership increasing by 0.38% to an effective 99.67%. The issuance of shares to the Company by Avino Mexico on June 4, 2013 resulted in a reduction in the non-controlling interest from 0.72% to 0.34%.

On August 26, 2015, the Company converted existing loans advanced to Avino Mexico into new additional shares, resulting in an increase of the Company’s ownership by 0.01% to an effective 99.67%. The intercompany loans and investments are eliminated upon consolidation of the financial statements. The Company had a pre-existing effective ownership interest of 99.66% in Avino Mexico prior to the 0.01% increase. The issuance of shares to the Company by Avino Mexico on August 26, 2015, resulted in a reduction in the non-controlling interest from 0.34% to 0.33%.

Mineral Concessions and Agreements

The current Property is comprised of 23 mineral concessions, totalling 1,103.934 ha. Of these, 22 mineral concessions totalling 1,005.104 ha, are held by Avino Mexico (Avino’s Mexican subsidiary company), Promotora Avino SA de CV, and Susesion de la Sra. Elena del Hoyo Algara de Ysita. Ownership proportions and mineral concessions are summarized in the tables following the next paragraphs regarding Claim Staking and Mineral Tenure in Mexico.

Claim Staking and Mineral Tenure in Mexico

In 1992, a new Mining Law was enacted and has been amended from time to time since then. In general, and for North American companies in particular, Mexican law permits direct or indirect 100% foreign ownership of exploration and mining properties. For practical purposes, most foreign companies establish Mexican subsidiaries. Mining companies are subject to the normal corporate income tax rate of 30%. Further, in 2014 the Mexican Government enacted a new tax reform which includes a 7.5% mining royalty calculated as taxable revenues (except interest and inflationary adjustment), less allowable deductions for income tax purposes (excluding interest, inflationary adjustment, mining concessions and depreciation and depletion), less exploration expenses, and a 0.50% mining royalty on the sale of silver and gold.

In December 2005, amendments to the mining law eliminated the distinction between “exploration” and “exploitation” concessions. Currently, the mining act and regulations provide solely for mining concessions (Concesiones Mineras), which are issued for a term of fifty years, renewable for an additional term of fifty years.

Owners of mining concessions are obliged to:

Note: Concession “La Platosa” is not included because it is not held by Avino.

Map of Avino Mine Property Concessions

On February 18, 2012, through its subsidiary company Avino Mexico, Avino re-entered into an agreement (the Agreement) with Minerales de Avino, S.A. de C.V. (“Minerales”), whereby Minerales has indirectly granted to Avino the exclusive mining and occupation rights to the La Platosa concession. The La Platosa concession covers 98.83 ha and hosts the Avino vein and ET Zone.

Pursuant to the Agreement, Avino has the exclusive right to explore and mine the concession for an initial period of 15 years, with the option to extend the agreement for another 5 years. In consideration of the grant of these rights, Avino must pay to Minerales the sum of US$250,000, by the issuance of common shares of Avino. Avino will have a period of 24 months for the development of mining facilities.

Avino has agreed to pay to Minerales a royalty equal to 3.5% of NSRs. If at the commencement of commercial production from the property the monthly processing rate of the mine facilities is less than 15,000 tonnes, then Avino must pay to Minerales in any event a minimum royalty equal to the applicable NSR royalty based on processing at a minimum monthly rate of 15,000 tonnes. In the event of a force majeure, Avino shall pay the minimum royalty as follows:

Minerales has also granted to Avino the exclusive right to purchase a 100% interest in the concession at any time during the term of the Agreement (or any renewal thereof), upon payment of US$8 million within 15 days of Avino’s notice of election to acquire the Property. The purchase would be completed under a separate purchase agreement for the legal transfer of the concession. This agreement replaces all other previous agreements.

During the month of May of each year, Avino must file assessment work made on each concession for the immediately preceding calendar year. During the months of January and July of each year, Avino must pay in advance the mining taxes which are based on the surface of the concession and the number of years that have elapsed since it was issued.

Consistent with the mining regulations of Mexico, cadastral surveys have been carried out for all the listed mineral concessions as part of the field staking prior to recording (Slim 2005d). It is believed that all concessions are current and up to date. Mineral concessions in Mexico do not include surface rights. Avino has entered into agreements with communal land owners (Ejidos) of San José de Avino, for the temporary occupation and surface rights of the concessions.

Based on a review of documents, issued title certificates and the unhindered residence on the Property, Tetra Tech has verified that Avino owns the concessions through its Mexican subsidiary company, Avino Mexico, and that there is no indication of any encumbrances at the site. Furthermore, the legal document prepared by Jesús Bermúdez Fernández, dated February 18, 2012, delineating the terms of the agreement on the La Platosa concession has been sourced for information.

History

Avino Mine

The Avino deposit was originally discovered around 1555 by the Spanish conquistador, Don Francisco de Ibarra. In 1562, Francisco de Ibarra, was appointed governor of the newly formed province of Nueva Vizcaya, in the Viceroyalty of Nueva España (New Spain) and, in 1563, founded the town of Durango. Francisco de Ibarra led several expeditions in search of silver deposits in the region and is recognized as having established Minas de Avino, present day Avino Mine; San Martín, Durango; and Pánuco, Sinaloa. Mining activities at the Avino Mine are said to have commenced in 1562-1563 and have been in production until the early 1900s. Operations at the Avino Mine continued up to the onset of the War of Independence (1810) when operations were interrupted but continued through to the early 1900s.

In 1880, the Mine were taken over by Avino Mines Ltd., a company controlled by American and English interests. With aid of new industrial technology the Avino ine developed into a more efficient mining operation. By 1908, the Avino Mine was considered one of the largest open pit mines in the world and equipped with one of the largest lixification smelters (Gallegos 1960; Bannon 1970; VSE 1977; Slim 2005d).

During the outbreak of the Mexican Revolution in 1910, proceeds from the mine supplied funds to the revolutionary forces. Since much of the fighting occurred in and around Durango and the risk posed by brigands hiding in the mountains was high, the mine was abandoned in 1912.

Between 1912 and 1968, the mine was worked intermittently on a very small scale (Avino Annual Report 1980). There is no known historical record of production from the Avino Mine during this period. The Avino Property was acquired under current ownership in 1968.

In 1968, the current operators of the Avino property acquired an initial 49% interest in the property. Initial mining was by open-cut in the oxide material from 1976 until 1992 when the stripping ratio was becoming excessive and sulphide content increasing, at which date the extraction was transferred to underground. This necessitated a mill change from the prior lead concentrate production to one of copper carrying silver and gold. In the 1990s a larger ball mill was installed to increase throughput to 1,000 t/d.

During the underground mining period starting in 1992, Trackless mining was adopted, with all underground advancement headings sized at 4m x 4m. Mine access from surface was by a spiral ramp from a portal on the south side of the hill and there is a secondary ramp– Rampo El Trompo – on the north side, close to the maintenance shop.

Production was by sub-level stoping with a sub-vertical increment restricted from 11m to 15m to countermine dilution arising from an occasional, semi-incompetent hanging-wall. Stopes were started by raising, and then slashing to the designated width. Blasting was by parallel holes drilled with a traditional drill wagon. Rib and sill pillars were left but are generally considered as non–recoverable.

Standard mine development was by using boom jumbo with waste being dumped where possible into old stopes. Ore mucking and haulage was by scoop tram and dumped on surface at the main portal. The ore was then picked up and transferred to the plant ROM hopper about 300 m away.

A surface-stacked, downstream tailings-system was adopted with cyclones on the tails discharge line to provide coarse wall-material. Decant water was recovered by a back-slope gradient and pumping, for mill re-circulation. A second, stepped-back bench was created, possibly about 1986 or 1987. A third bench was started, apparently in 1990, with about two years placement of final oxide material then continued with the sulphide tails.

The Avino Mine and processing plant were serviced by a heavy equipment repair shop, mechanical and electrical shops, assay office, metallurgical laboratory, warehouse and other auxiliary facilities. Electric power was supplied by the government-owned Federal Electricity Commission.

In November 2001, delays in payments, low metals prices and the closure of the toll smelter led to the suspension of mine operations. During the 27 year period of extracting and processing resources starting in 1974, output from the Avino mine totalled approximately 497 tons of silver, three tons of gold, and 11,000 tons of copper. When mining activities stopped, level 12 of the mine had been reached.

The property was mainly dormant from 2002 to 2006, largely due to low copper and silver prices.

San Gonzalo Mine

The history of the San Gonzalo deposit is not well known. Shallow workings from an old mine are present in the San Gonzalo vein, and consist of small underground workings which were originally accessed by a five-level vertical shaft. These workings were sampled by M. Evans in 1954. The workings are accessible through a raise that was driven in 2012 which is being used for ventilation. No attempts have been made to duplicate the results of the 1954 sampling. The limits of past workings have been taken from old maps but are assumed to be reasonably accurate (Gunning 2009).

Current Condition

San Gonzalo Mine

Avino gained control of the property in July 2006 and exploration (see exploration section below) resumed that year; this led to the discovery of new mineralization at San Gonzalo.

The original underground workings extend over an area approximately 150 m along strike and 136 m in depth. In 2007-08 Avino conducted a 42-hole, 9,204 meter drill program to explore the San Gonzalo deposit. Drilling produced encouraging results which were input into a resource calculation in 2009.

Following a 2009 mineral resource estimate, independently verified preliminary metallurgical testing on a composite sample of San Gonzalo material was completed at SGS Minerals Services in Durango, Mexico. The results indicated the silver and gold minerals from the San Gonzalo vein at lower levels would respond favorably to flotation with gold recoveries of 89 to 90% and silver recoveries of 92 to 93%.

The San Gonzalo mining activities began in January 2010. DMG, the mining contractor, was contracted to provide this service. Their original scope of work was to drive the main haulage decline to level 2 and to intersect the vein; drift and sample to the east and the west on the vein, and to determine the extent of the mineralized zones and to extract the 10,000 tonne bulk sample for testing as per the recommendations of the Orequest Mineral Resource Estimate Report. A smaller decline to level 1 was also commissioned and its purpose was for ventilation and an escape route once the two levels were connected by raises from level 2 to level 1. This scope of work was extended with the successful completion of the bulk sample program, and mining continued with the aim of developing San Gonzalo to a state whereby it could provide mill feed at the rate of 250 tonnes per day on a sustained basis.

Processing of San Gonzalo material began in late November 2010 in the newly refurbished 250 tonne per day bulk flotation circuit. Testing with extracted material was performed initially to ensure the circuit was operating satisfactorily before the bulk sample test with material from the stopes began in January of 2011. The bulk sample test continued until early April 2011 when the limit of 10,000 tonnes was achieved for the independent verification. Processing of the remaining San Gonzalo material on stockpile continued until the middle of May. During this period of November 2010 to May 2011, the plant processed a total of 19,850 tonnes leaving approximately 14,798 tonnes remaining on stockpile in inventory by calculation.

The majority of the concentrate processed during the bulk sample test was sold and the assays from the concentrate sale were used to reconcile the mill balance as reported following the verification of the bulk sampling results. All the remaining concentrate processed from the extracted material was shipped and sold early in 2012.

Following the completion of the bulk sample which was comprised of material from levels 1 and 2, mine advancement at San Gonzalo has been ongoing. In 2012, the remaining material from the stopes on level 2 was mined and brought to the surface. During 2012, level 3 was the main focus of mining activities with two stopes having been developed and partially extracted by the end of the year. By the end of July, a decline from level 3 to level 4 had been completed and work on the ramp to level 5 had commenced. By year-end, level 5 had been reached and stope advancement on level 4 was underway. Underground advancement for 2012 totaled 2,558 meters consisting of ramp advancement, cross cuts, drifts and raises.

During 2013 the extraction of resources came mainly from level 4. Advancement of level 5 was ongoing and by year end a sampling program totaling 440 meters had been completed. The ramp from level 5 to level 6 had been completed by April 2014.

During 2014, mine exploration and advancement included the discovery of significant additional mineralization along strike to the southeast while drifting on level 5. These areas had not previously been considered for mining. Following this discovery, the extension of this new mineralized zone was explored on levels 2 through 6. Previous exploration did not encounter this area as the vein had pinched out and an offset of the vein was not considered at that time. During 2014, extraction of resources came primarily from levels 5 and 6 as well as from mined material from the new zone on level 3. Advancement work on level 6 continued throughout the fourth quarter, and by year end the main haulage ramp had progressed past the level 7 elevation of 2,043 meters above sea level towards level 8.

During 2015, San Gonzalo mill feed came primarily from stopes on levels 4, 5 and 6. During the second quarter, the ramp advance was deferred (at 70 metres below level 7) in favor of using the mining equipment to advance levels 5, 6 and 6.5 laterally along the San Gonzalo structure to the East and West where the new mineralized zones were identified in 2014.

During 2016, San Gonzalo mill feed came from stopes on level 4, 5, 6 and 7 with the bulk of the tonnage coming from stopes 4-050, 5-030, 5-500, 5-600, 6-030, 6-100 and 7-070.

Access to the underground at San Gonzalo is via a 4m by 4m decline developed at -12%. The decline is developed at about 20m to 25m from the mineralized material. San Gonzalo is using shrinkage mining for the narrower mineralized material, ~1.4m in width and cut and fill mining for mineralized material wider than 2m.

The San Gonzalo Mine has been the subject of three mineral resource estimates, the most recent of which was published on October 28,2016; please see the section below on Mineral Resource Estimates for more details.

Avino Mine

In February 2012, a new long-term royalty agreement was signed to grant Avino mining rights to the main Avino vein. At the time of signing this agreement, Avino planned to refurbish the existing 1,000 TPD circuit to process the material from the main Avino vein.

To resume underground advancement at the Avino Mine, the existing underground workings had to be de-watered; the dewatering process was completed in May 2014. The process lasted for a total of 482 days, and successfully removed 1,013,069 cubic meters of acidic water which was then treated for the removal of base metals using lime. The treated water, which met agricultural standards for discharge, was used for mill processes and the excess was gravity fed to the Company-built La Caricol dam; sludge from the water treatment plant was disposed of in the tailings storage facility.

Following dewatering and rehabilitation of the haulage ramp, underground mining activities re-commenced at the Avino Mine. Full scale mining began at level 11.5 with drifts heading east and west along the vein during the third quarter of 2014. By the end of 2014, a total of 877 metres of underground advancement had taken place on levels 11.0 and 12.0 with the haulage ramp advancing to level 12.5.

Initially, new material from underground at Avino was processed on a limited scale using the existing 250 TPD Mill Circuit 2. By year end, rehabilitation of the 1,000 TPD Mill Circuit 3 had been completed and sufficient material had been stockpiled; on January 1, 2015, the Company commenced testing of mining and milling methods at levels anticipated for full-scale activities.

During 2015, underground advancement totalled 5,056 metres and took place mainly in levels 12.5 to 14.5 with the ramp advancing to level 15. The breakdown of the advance in 2015 consisted of 2,855 metres of drifts, 785 metres of ramp, 1,050 metres of crosscuts and 366 metres of raises.

During 2016, underground advancement totaled 3,901 metres with the ramp advancing to level 16. Breakdown of the advance consisted of 1,489 metres of drifts, 415 metres of ramp 1,609 metres of crosscuts and 390 metres of raises. Production mining with the Trac Drill took place on levels 12, 12.5 and 14.5. Mill feed from development mining came from levels 14.5, 15, 15.5 and the crosscuts towards the hanging wall breccia on levels 12.5 and 14.5 where high gold values were encountered.

The Avino Mine has been the subject of two mineral resource estimates, the most recent of which was published on October 28, 2016; please see the section below on Mineral Resource Estimates for more details.

Tailings Resource

Avino continues to explore options for exploiting the mine's tailings resource left from past mining of the Avino Vein. The tailings are situated approximately 500 m west-southwest of the main shaft to the main Avino mine.

This asset includes oxide and sulphide tailings, each requiring separate treatment methods. The tailings resource was created during between 1976 and 2001 during Avino's previous operation from both open pit (oxide tailings) then later underground (sulphide tailings) mining. Improved metals markets now potentially enable Avino to process the remaining silver and gold in the tailings.

The existing tailings storage facility is presently being used in connection with the operation of Mill Circuits 1, 2, and 3. In 2016, the Company finalized plans to build a new tailings storage facility which is necessary to allow the existing TSF to be decommissioned, which will enable Avino to begin assessing the upper sulphide bench as well as the lower oxide bench in areas that are currently being used to store tailings from our active operations. The assessment work is part of the recommendations contained in a 2013 technical report intended to advance the Tailings Resource towards a production decision for an agglomerated heap leach Merrill-Crowe precipitation operation.

The oxide tailings were produced between 1974 and 1993 from open pit mining of the main Avino vein. For further details regarding the oxide tailings, please see the section below titled: Mineral Resource Estimates or the Company’s Amended Resource Estimate Update for the Avino Property, Durango, Mexico dated October 27, 2016.

Project Infrastructure

The Avino Mine is connected to the local power grid with a line capacity quoted at 4 MW when the mine last operated in 2001. With the shutdown, much of this excess power was diverted to the surrounding towns in the district. Between 2001 and 2016 the powerline provided only 1,000 kW of power with 500 kW servicing the mill, 400 kW for San Gonzalo and the balance for the well at Galeana, the employee accommodation facility and water reclamation from the tailings dam. In 2009 a power line to the San Gonzalo Mine was built to replace the contractor’s diesel generator used during mine advancement.

Discussions with CFE, the federal electricity commission in Mexico, on a new 34.5kV power line were completed in 2014 along with a study covering the proposed locations of towers and power poles. Additionally, in October 2014, CFE informed the Company that it had completed internal upgrades to several transformers that would enable CFE to provide Avino with sufficient grid power to operate all three mill circuits and both underground locations in the interim period prior to the commissioning of the new power line. Construction of the new power line was completed in 2015; and energized in June 2016. The new line is now fully functional at the design capacity of 5 megawatts ("MW"). Current power consumption at the mine is approximately 2MW, leaving sufficient additional power for near-term expansion projects that are currently being organized, such as the Oxide Tailings Heap Leach/Merril-Crowe Precipitation Project (which would require 1 MW) and a possible expansion of the processing plant, which would require a further 1 MW.

While water supply was found to be limiting in the past, Avino has taken the necessary steps to secure adequate supply. To supplement the 1 Mm ³ dam built by Avino in 1989, a well (Galeana) was drilled to the west of the mine site in 1996 to a depth of 400 m and is reported to have a water level at 40 m below the collar. From this, a pipeline connection has been installed to the mine. Additionally, Avino Mexico, in cooperation with the government, has repaired a government dam (El Caracol) and raised the dam wall by 6 m. A pipeline to the mine has also been installed. This dam is shared with the population of Pánuco de Coronado for their irrigation needs, as 60% for the mine and 40% for the town, with government setting the annual total take to which percent sharing applies. Mine site water use is from a combination of tailings water reclaim, El Caracol, and Galeana with preference given to mine site sources for which no water conservation charge was applicable (Slim 2005).

Both the San Gonzalo and Avino mines are equipped with two mine dewatering pumps. The pumps at San Gonzalo are each capable of pumping 20L/s to surface via 2 six inch lines. One pump operates 24 hours per day and the other 10 hours per day. At Avino one pump operates constantly with the second on standby. Each pump is capable of handling the entire inflow via a 6 inch line. Water from both mines is pumped to the surface and is sent to the process water tanks in the plant. Any water not used in the plant flows by gravity to the La Caricol Dam for agricultural use.

Processing Plant

In September 2006, the Company conducted a review of the plant, including the condition of all equipment, capacity of each circuit, and efficiency of the plant. The review was an order of magnitude cost estimate for putting the plant back into operation at the rate of 1,000 tpd, which was approximately $3 million. In the property valuation, the replacement cost of the mill was estimated at roughly $40 million.

The Company’s processing plant was built in the 1970’s and was refurbished to accommodate increased capacity in 1993. Most of the infrastructure was in place for two 250 tpd circuits and one 1,000 tpd circuit. At the time of shutdown in 2001 due to low commodity prices and the closure of a smelter, the mill was operating at an average rate of 1,130 tpd.

In order to perform the bulk sample program at San Gonzalo, major infrastructure spending and mill repairs were required. Most of these expenditures took place in 2008 and 2009 with additional spending required more recently as further needs arose to meet the demands of mining activities.

Beginning in May 2011, when the San Gonzalo stockpiled material was depleted following the bulk sample, the process plant was used to treat old stockpiles from historic extraction at the Avino Mine. These were lower-grade stockpiles which were originally considered marginal or waste due to prevailing metal prices at the time. These stockpiles were processed until underground advancement at San Gonzalo was sufficient to provide mill feed at a sustained rate of 250 tonnes per day. On October 1, 2012, Avino made the transition to San Gonzalo mill feed and declared that resource extraction and processing had reached levels intended by management at San Gonzalo.

During the second quarter of 2013, a second 250 tpd circuit (“Mill Circuit 2”) in the mill was commissioned and put into operation for the processing of remaining Avino Mine surface stockpiles. In September 2014, Mill Circuit 2 began processing new mineralized material from the Avino Mine during the mine’s commissioning phase. On January 1, 2015, Mill Circuit 2 transitioned to processing feed material from the San Gonzalo Mine stockpile which continued throughout the first half of 2015 apart from May, when Mill Circuit 2 was once again used to process Avino Mine surface stockpiles. During the second half of 2015, Mill Circuit 2 was used to process mineralized material from the Avino Mine underground in July, August, November and December; and mineralized material from the San Gonzalo Mine during September and October. In 2016, Mill Circuit 2 is expected to primarily process mineralized material from the Avino Mine.

In November 2014, Avino completed its Mill Circuit 3 expansion in preparation for the re-opening of the main Avino Mine. The refurbished circuit was initially commissioned using historic above ground Avino Mine stockpiles during November and December of 2014. Mill Circuit 3 began processing new mill feed from underground at the Avino Mine beginning on January 1, 2015. During 2015, Mill Circuit 3 was optimized to process approximately 1,150 tonnes per day. In the second quarter of 2016, the Company declared that effective April 1, 2016, extraction and processing had reached levels intended by management at the Avino Mine.

*No feasibility study or preliminary economic assessment has been carried out at the Avino Mine. The Company has determined extraction and processing of resources at levels intended by management without undertaking any further formal studies.

In January 2017, Avino announced plans to further expand the mills to an overall throughput capacity of 2,800 tonnes per day. The addition of Mill Circuit 4, which will be an exact duplication of Mill Circuit 3, commenced in January 2017, and will take approximately one year to complete. It is planned that Mill Circuit 4 will be used to process material from the Avino Mine.

Mining Fleet

To operate the Avino and San Gonzalo Mines, Avino’s mining fleet currently consists of 3 front end loaders, a D6R Cat dozer, 11 scoop trams, 5 jumbos, 2 combination backhoe and rock breakers, a surface and an underground diamond drill, 2 mini loaders, a CAT grader suitable for both surface and underground, 20 contractor provided haulage trucks, a shotcrete machine, 27 light service passenger vehicles, a contractor provided water truck, a 15 tonne capacity contractor provided truck to distribute explosives and a contractor provided fuel truck, 3 power generators, 5 air compressors and an ambulance

If the Company is unable to raise capital to meet its planned future costs, it may have to curtail planned activities.

Mineral Reserve Estimates

There are currently no mineral reserves on the Property.

Mineral Resource Estimates

Below is a summary of current mineral resources at the San Gonzalo and Avino Mines as well as the oxide tailings resource (as reported in the October 2016 Amended Resource Estimate Update for the Avino Property) grouped into the measured, indicated and inferred categories. The effective date of the resource estimates is August 31, 2016.

The resource estimates were prepared by Michael O’Brien P.Geo., Pr.Sci.Nat., who is a “Qualified Person” within the meaning of National Instrument 43-101 and who is an employee of QG Australia Pty Ltd (an ARANZ Geo Company) and independent of Avino, as defined by Section 1.5 of NI 43-101.

Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues. The quantity and grade of reported Inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred resources as an Indicated or Measured mineral resource and it is uncertain if further exploration will result in upgrading them to the Indicated or Measured mineral resource category.

Figures in the table may not add to the totals shown due to rounding.

The mineral resource estimate is classified in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum's "CIM Definition Standards - For Mineral Resources and Mineral Reserves" incorporated by reference into National Instrument 43-101 "Standards of Disclosure for Mineral Projects".

Mineral Resources are reported at cut-off grades 55, 125 and 50 g/t silver equivalent grade for the Avino, San Gonzalo and oxide tailings respectively as indicated in the table.

Method of Calculation

The estimation methods used were substantially the same for all three deposits, providing a consistent baseline for strategic planning.

Mineral resources were estimated by ordinary kriging, optimized using kriging neighborhood analysis and verification by means of nearest neighbor and inverse distance methods, swathplot comparisons of estimates and visual inspections. Block models were created for the San Gonzalo and Avino Vein Systems and the oxide Tailings deposit and estimates were made into blocks of sizes 10m easting x 5m northing x10m elevation (San Gonzalo and Avino) and 40m easting x 40m northing x 2m elevation (oxide Tailings).

Classification of the mineral resource was based on kriging variance as a measure of uncertainty with adjustment to practical geometries using geological knowledge of the deposit.

Silver equivalent cut-off grades were applied to satisfy the condition of reasonable prospects for eventual economic extraction and were calculated using conversion formulas AgEQ = Ag + 55.9 * Au + 72.99 * Cu for Avino Vein, AgEQ = Ag + 69.37 * Au for oxide tailings and AgEQ = Ag + 56.38 * Au for San Gonzalo vein System.

Cut-off grades were calculated using current costs, silver price of US$19.50/oz, gold price of US$1,250/oz and copper price of US$2.10/lb. 

Since 2013, Avino has drilled 57 new holes on the oxide tailings deposit, nearly three thousand channel samples representing 14,470 metres of vein material have been obtained on the Avino and San Gonzalo Veins, and 46 surface drill holes, (totaling 7,960 m) have been drilled on the San Gonzalo and Avino vein systems. This investment has significantly increased the amount of information available for resource estimation.

Fundamental changes since the previous mineral resource estimates are (1) depletion due to mining (over 1 million tonnes milled since the beginning of 2013), significant new sampling information (almost double in the case of the Oxide Tailings) (3) changes to silver equivalent calculation and cut-offs and (4) reclassification of mineral resources in the light of improved understanding of confidence in the deposits at distances from the underground channel samples and drill hole samples. More sampling information does not always lead to direct increases in resource tonnages and metal. In some cases, the new information provides improved understanding (developed by variogram modelling and kriging neighborhood analysis) that may demote some portions of mineral resource from high confidence categories such as measured and indicated to a lower confidence category such as inferred. Currently, for the San Gonzalo and Avino Vein Systems, estimated blocks more than thirty metres from sampling are not considered to be of sufficient confidence to be indicated category resources and have been classified as inferred resources. Consequently, the total indicated resources for the Avino Property are significantly less than those were reported previously. For the Oxide Tailings, estimated blocks more than fifty metres from sampling are not considered to be of sufficient confidence to be indicated category resources.

San Gonzalo Mine – Resource Depletion

The mineral resource estimate at San Gonzalo factors in depletion from ongoing mining activities up to the effective date of August 31, 2016. Between the effective date and December 31, 2016 a total of 46,539 tonnes were extracted.

Avino Mine – Resource Depletion

The mineral resource estimate at San Gonzalo factors in depletion from ongoing mining activities up to the effective date of August 31, 2016. Between the effective date and December 31, 2016, a total of 133,965 tonnes were extracted.

Exploration

Early Drilling (Prior to Mine Closure), 1968 to 2001

Avino Vein

Between 1968 and 2001, at least 25 diamond drill holes, ranging in length from 132 to 575 m, are reported to have been drilled from surface into the Avino vein. Included in this total are 10 holes that were drilled by Selco in 1970 when they were re-habilitating some of the old underground workings to provide access for sampling (Slim 2005d). No further information on these drill holes was available to Tetra Tech and they are not included in the resource estimate for the Avino vein.

Oxide Tailings, 1990 to 1991

Between November 10 and December 5, 1990, and March 8 and May 30, 1991, Avino completed six trenches and 28 vertical drill holes in the tailings along 7 fences at a spacing of roughly 50 m by 50 m (Benitez Sanchez 1991). Drilling was completed transversely to the drainage pattern of the tailings. Cut at 1 m vertical increments, 461 samples were assayed for silver and gold at the mine assay lab and occasional moisture contents were reported. Assay results from these drill holes have been previously reported (Tetra Tech 2013).

Recent Drilling (Post Mine Closure), 2001 to Present

A total of 156 surface and underground drill holes have been completed on the Avino and San Gonzalo veins, totalling 35,846.5 m. Additional exploration holes have been drilled elsewhere on the Property, but those drilling results are not considered material. Most holes were surveyed down hole using a Tropari single-shot magnetic instrument. Of those holes for which down hole surveys were completed, the majority contain three or fewer measurements, typically at the collar and near the end of hole, and sometimes part-way down the hole. Many holes were not surveyed to within 10 m of the end of the hole.

Geophysical Surveys: Induced Polarization (IP)

In December 2006, Avino conducted an 80 km line deep penetrating IP survey at the property. IP geophysics helps identify drill targets. The IP survey was completed in 2007. Avino did follow-up soil geochemical, satellite imagery and other surveys to better define targets in the covered areas.  

Avino Vein (including ET Zone) and Nearby Veins

Since 2001, Avino has drilled 34 holes below Level 12, where mining ceased, for a total of 11,523.2 m. Drilling has targeted the ET Zone in particular. There were 5 holes completed in 2006 (2,166.85 m), 12 holes in 2007 (3,906.5 m), 8 holes in 2008 (2,186.7 m), and 9 holes in 2012 (3,263.15 m).

In late September 2016, Avino began an exploration diamond drilling program between the San Luis Mine, which was last mined in the 1990’s, and the ET Mine, which is the area of current production; both areas are part of the Avino Mine.

The area between the two mines is approximately 300 metres long and 220 metres deep and was recently the subject of a geological review where it was determined that the main Avino vein showed economically viable values, was open at depth and was largely underexplored. The program has thus far been comprised of 18 holes totaling 2,955 metres, with positive results from the first 8 holes which were released in December, with the results from the remaining ten holes still pending. The drill results support the continuation of the extensive Avino vein system. This new area is close to surface and accessible from the existing Avino Mine underground workings. Assay results from all drill holes up to and including ET-12-06 have been previously reported (Tetra Tech 2012).

Tecmin Servicios, S.A. de C.V., was contracted for the 2007 and 2008 drilling programs at the ET Zone of the Avino vein. Since the Avino deposit strikes approximately east-west and dips at 60° to 70° to the south, holes are generally oriented from south to north at various bearings and dip angles in order to intersect the structure at a target depth. Holes were drilled using Avino’s Longyear 44 core rig at thin wall NQ diameter.

San Gonzalo and Nearby Veins

At San Gonzalo, Avino drilled 40 holes in 2007 (9,222.9 m), 6 in 2008 (1,782.65 m), 18 in 2011 (3,618.57 m), 15 in 2014 (3,631.93 m), and 25 in 2015 (3,197.60m) for a total of 104 drill holes and 21,453.65 m. All holes were of thin wall NQ size core diameter and were completed using Avino’s Longyear 44 core rig with the exception of 6 underground holes in 2014 and 14 in 2015. Additional holes also explored the nearby Guadalupe, San Juventino, San Lucerno, Mercedes, San Jorge, and Yolanda veins.

According to Gunning (2009), the collars for 2007 and 2008 drill holes were marked by concrete monuments and the collars have been surveyed. A check of the coordinates with a handheld global positioning system (GPS) revealed a possible 10 m constant error which may simply mean that all of the mine coordinates are not precisely Universal Transverse Mercator (UTM). However, this could also indicate the existence of a small surveying error on the Property.

In 2011, 69 holes totalling 9,862.97 m were drilled principally in the following locations: San Gonzalo (18 holes, as above), Aguila Mexicana (2 holes), Guadalupe (25 holes), La Potosina (9 holes), Mercedes (1 hole), San Jorge (3 holes), San Juventino (3 holes), San Lucero (5 holes), Tucero (1 hole), and Yolanda (2 holes). With the exception of the San Gonzalo vein, all of these locations are considered targets for further exploration.

In 2014, Avino undertook a 15 hole (3,631.93 m) surface and underground definition drill program to test the San Gonzalo vein at depth. In April 2014, a 70 meter cross cut was completed on level 6, and the underground drill program started on May 2. Three holes were drilled from the cross cut (SG-14-01 through SG-14-03).

Surface drill holes SG-14-04 through SG-14-10 were drilled between June and October 2014. Hole SG-14-11 was an underground hole drilled in October 2014 from the end of the San Gonzalo level 6 crosscut (same location as SG-14-01 through SG-14-03).

Holes SG-14-12 and SG-14-13 were drilled during October and November 2014 from the end of a crosscut on level 7. A sudden inflow of water on November 17, 2014 caused hole SG-14-13 to be terminated. Surface drilling later resumed and holes SG-14-14 and SG-14-15 were drilled by December 31, 2014.

In 2015, the Company continued its definition drill program intended to define the boundaries of the San Gonzalo structure. In total, 25 holes were completed totaling 3,197.60m metres. From January 2015, through the end of April, 19 holes were drilled of which 5 were from surface and 14 were underground holes (SG-15-1 through SG-15-16). Drilling resumed in September 2015 with Hole CH-07-01 which was the deepening of a hole drilled in 2007 on the Chihuahua vein, which is an extension of the San Gonzalo structure. Drilling then resumed at San Gonzalo to test the southeast extension of the structure; drilling for the year concluded in November with the completion of hole SG-15-24. No holes were drilled at San Gonzalo in 2016.

Reclamation

The Company has mine closure and reclamation plans for the Avino and San Gonzalo Mines and has estimated the undiscounted value of reclamation at approximately $1.7 million for the Avino Mine and approximately $0.3 million for the San Gonzalo Mine as at December 31, 2016.

As per Federal Mexican regulations (LGEEPA), both the SEMARNAT and PROFEPA ministries require Avino to present in its first semi-annual report a “General Plan to Remediate the Site” including dates, activities, techniques, and costs that will ensure restoration of affected areas, considering complete reforestation of impacted sites, removal of foundations and infrastructure that are no longer useful, roads that no longer have any use, removal and proper disposal of all rubbish, closing off adits that are no longer needed and restoration of the tailings facility at the end of its operational life. Avino will also need to present a reforestation program for the entire surface area affected during mining activities. This program will include caveats to safeguard flora and fauna.
