SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

Please see the note under “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations,” for a description of special factors potentially affecting forward-looking statements included in this report.

CAUTIONARY NOTE TO UNITED STATES INVESTORS—INFORMATION CONCERNING

PREPARATION OF RESOURCE AND RESERVE ESTIMATES

McEwen Mining Inc. (“McEwen Mining,” “we”, “our”, “us” or the “Company”) is required to prepare reports under the Securities Exchange Act of 1934 and the Canadian Securities Administrators’ National Instrument 43-101 “Standards of Disclosure for Mineral Projects” (“NI 43-101”), under the Canadian securities laws because we are listed on the Toronto Stock Exchange (“TSX”) and subject to Canadian securities laws. Standards under NI 43-101 are materially different than the standards generally permitted in reports filed with the United States (“U.S.”) Securities and Exchange Commission (“SEC”) under Industry Guide 7 (“Guide 7”).

Definitions of terms under NI 43-101 differ materially from the definitions of those and related terms under Guide 7 promulgated by the SEC. Under Guide 7, mineralization may not be classified as a “reserve” unless a determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Under Guide 7 standards, a “final” or “bankable” feasibility study or other report is required to report reserves, the three-year historical average precious metals prices are used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate government authority.

One consequence of these differences is that “reserves” calculated in accordance with Canadian standards may not be “reserves” under Guide 7 standards. U.S. investors should be aware that the McEwen Mining properties with reserves as defined by Guide 7 are the Black Fox mine, the Gold Bar mine and the San José mine. All other properties do not have “reserves” as defined by Guide 7 and Investors are cautioned not to assume that any part or all of the disclosed mineralized material will be confirmed or converted into Guide 7 compliant “reserves”.

Further, since we have no reserves on some of our properties as defined in Guide 7, we have in the past and will continue to expense substantially all design, construction and development costs with regard to those properties, even though these expenditures are expected to have a future economic benefit in excess of one year. Only certain types of property and equipment which have alternative uses or significant salvage value may be capitalized without proven and probable reserves. We also expense our asset retirement obligations on those properties. Companies that have reserves under Guide 7 typically capitalize these costs, and subsequently depreciate or amortize them on a units-of-production basis as reserves are mined. Unlike these other companies, on our properties that have no reserves we depreciate or amortize any capitalized costs based on the most appropriate amortization method, which includes straight-line or units-of-production method over the estimated life of the mine, as determined by our internal mine plans. Because of these and other differences, our financial statements may not be comparable to the financial statements of mining companies that have established reserves on all of their properties.

Under NI 43-101, we report measured, indicated and inferred resources, which are measurements that are generally not permitted under Guide 7. The estimation of measured and indicated resources involve greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves under Guide 7. U.S. investors are cautioned not to assume that any part of measured or indicated resources will ever be converted into economically mineable reserves. The estimation of inferred resources involves far greater uncertainty as to their existence and economic viability than the estimation of other two categories of resources. Inferred mineral resources could be upgraded to indicated mineral resources with continued exploration. Therefore, U.S. investors are also cautioned not to assume that all or any part of inferred resources exist, or that they can be legally or economically mined.

Canadian regulations permit the disclosure of resources in terms of “contained ounces” provided that the tonnes and grade for each resource are also disclosed; however, Guide 7 only permits issuers to report “mineralized material” in tonnage and average grade without reference to contained ounces. Under U.S. regulations, the tonnage and average grade described herein or disseminated by us would be characterized as mineralized material. We provide such disclosure about our properties to allow a means of comparing our projects to those of other companies in the mining industry, many of which are Canadian and report pursuant to NI 43-101, and to comply with applicable disclosure requirements.

We also note that drill results are not indicative of mineralized material in other areas where we have mining interests. Furthermore, mineralized material identified on our properties does not and may never have demonstrated economic or legal viability.

RELIABILITY OF INFORMATION

Minera Santa Cruz S.A. (“MSC”), the owner of the San José mine, is responsible for and has supplied to us all reported results from the San José mine. The technical information contained herein with regard to the San José mine is, with few exceptions as noted, based entirely on information provided to us by MSC. Our joint venture partner, a subsidiary of Hochschild Mining plc, and its affiliates other than MSC do not accept responsibility for the use of project data or the adequacy or accuracy of this information.

PART I

ITEM 1. BUSINES S

History and Organization

We are a mining and minerals production and exploration company focused on precious and base metals in the United States, Canada, Mexico and Argentina. We were incorporated under the laws of the state of Colorado in 1979. We own 100% of the Black Fox mine and Stock mill in Ontario, Canada, a 100% interest in the Gold Bar mine in Nevada, 100% of the formerly-producing El Gallo Project in Sinaloa, Mexico, and a 49% interest in MSC, the owner and operator of the San José mine in Santa Cruz, Argentina. MSC is controlled by the majority owner of the joint venture, Hochschild Mining plc (“Hochschild”). Since we own less than a 50% interest in MSC, we account for our interest as an unconsolidated subsidiary using the equity method of accounting. In addition to our operating properties, we hold interests in advanced-stage and exploration-stage properties and projects in the United States, Canada, Mexico and Argentina, including the Los Azules (“Los Azules”) copper project in Argentina.

Our commencement of Canadian operations in 2017 was facilitated by the acquisition of Lexam VG Gold Inc. (“Lexam”) in April 2017 and the acquisition of the Black Fox mine and Stock mill in October 2017. These two acquisitions provided us an operating mine, mill and significant land interests in the historic Timmins mining district of Ontario.

Our 100% owned Gold Bar mine in Nevada poured its first gold ingot on February 16, 2019 and achieved commercial production on May 23, 2019. Construction activities started in late 2017 following the receipt of the final permit on November 8, 2017. At the El Gallo Project, mining and crushing activities ceased during the second quarter of 2018, with production activities since that time limited to residual leaching.

Our objective is to increase shareholder value through the exploration for and economic extraction of gold, silver and other valuable minerals. Other than the San José mine in Argentina, we generally conduct our activities as the sole operator, but we may enter into arrangements with other companies through joint venture or similar agreements in an effort to achieve our strategic objectives. We hold our mineral property interests and operate our business through various subsidiary companies, each of which is owned directly, or indirectly, by us.

Our principal executive office is located at 150 King Street West, Suite 2800, Toronto, Ontario, Canada M5H 1J9 and our telephone number is (866) 441-0690. We also maintain offices in Elko, Nevada (U.S.), Matheson, Canada, Guamuchil, Mexico, and San Juan, Argentina. Our website is www.mcewenmining.com. We make available at no cost our periodic reports including Forms 10-K, 10-Q and 8-K, and news releases and certain of our corporate governance documents, including our Code of Ethics, on our website. Our common stock is listed on the New York Stock Exchange (“NYSE”) and on the Toronto Stock Exchange (“TSX”) under the symbol “MUX”.

In this report, “McEwen Mining”, the “Company”, “our” and “we” refer to McEwen Mining Inc. together with our subsidiaries, unless otherwise noted. “Au” represents gold; “Ag” represents silver; “Cu” represents copper, “oz” represents troy ounce; “gpt” represents grams per metric tonne; “ft.” represents feet; “m” represents meter; “sq.” represents square, and C$ refers to Canadian dollars. All our financial information is reported in United States (U.S.) dollars, unless otherwise noted.

Segment Information

Our operating segments include USA, Canada, Mexico, MSC and Los Azules. Financial information for each of our reportable segments can be found under Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations and Item 8. Financial Statements and Supplementary Data, Note 3, Operating Segment Reporting.

Products

The end product at our gold and silver operations is either in the form of doré or concentrate. Doré is an alloy consisting primarily of gold and silver but also containing other impurity metals. Doré is sent to third party refiners to produce bullion that meets the required market standard of 99.95% gold and 99.9% silver. Ore concentrate, or simply concentrate, is raw mineralized material that has been ground finely to a powdery product from which gangue (waste) is removed, thus concentrating the metal component. Concentrate, as well as slag and fine carbons (by-products of the gold production process), are sent to third party smelters for further recovery of gold and silver.

Table of Contents

During 2020, production from the Gold Bar mine consisted of 100% doré, the production at the Black Fox mine was 99% doré and 1% slag and fine carbon and from the El Gallo Project approximately 97% doré and 3% slag and fine carbon. Production from the San José mine consisted of approximately 44% doré and 56% concentrate.

​

During 2020, we reported the following consolidated production attributable to us:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | Gold |  | Silver |  | Gold equivalent
Consolidated Production | ​ | ounces | ​ | ounces | ​ | ounces(1)
Gold Bar mine | ​ | 27,910 | ​ | 691 | ​ | 27,918
Black Fox mine |  | 24,337 |  | 1,395 |  | 24,353
El Gallo Project | ​ | 8,012 | ​ | 4,935 | ​ | 8,072
San José mine (on 49% basis) |  | 31,843 |  | 2,013,048 |  | 54,500
Total Production | ​ | 92,102 | ​ | 2,020,069 | ​ | 114,843

(1) | Calculated using an average silver to gold ratio of 86:1 at the 100% owned operations and a ratio of 89:1 at the San José mine. With a ratio of 86:1, gold equivalent ounces at the San José mine amount to 55,250.

Gold and silver bullion obtained from the doré produced in USA, Canada, Mexico and the San José mine is sold at the prevailing spot market price. Concentrates produced by the San José mine are provisionally priced, whereby the selling price is subject to final adjustments at the end of a period ranging from 30 to 90 days after delivery to the customer. The final price is based on the market price at the relevant quotation period stipulated in the contract. Due to the time elapsed between shipment and the final settlement with the buyer, MSC estimates the prices at which sales of metals will be settled. At the end of each financial reporting period, previously recorded provisional sales are adjusted to estimated settlement metals prices based on relevant forward market prices until final settlement with the buyer.

During 2020, revenues from gold and silver sales were $48.9 million for the Gold Bar mine, $41.4 million for the Black Fox mine, $14.5 million for the El Gallo Project, and $107.4 million for the San José mine on a 49% basis. Revenue from the San José mine is not included in our Consolidated Statements of Operations and Comprehensive (Loss) as we use the equity method of accounting for MSC. See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations for additional information regarding production and operating results for our properties, and Item 8. Financial Statements and Supplementary Data, Note 2, Summary of Significant Accounting Policies—Investments and Note 10, Investment in Minera Santa Cruz S.A. (“MSC”) – San José Mine for additional information regarding the equity method of accounting.

Like all metal producers, our operations are affected by fluctuations in metal prices. The following table presents the annual high, low and average daily London P.M. Fix prices per ounce for gold and London Fix prices per ounce for silver over the past three years and 2021 to the most recent practical date on the London Bullion Market:

On March 10, 2021, the London P.M. Fix for gold was $1,716 per ounce and the London fix for silver was $25.65 per ounce.

Mineralized Material Processing Methods

Gold and silver are extracted from mineralized material by either milling or heap leaching depending on, among other things, the amount of gold and silver contained in the material, whether the material is naturally oxidized or not, and the amenability of the material to treatment. At the Gold Bar mine and the El Gallo Project, both open pit operations, the mineralized material is processed using heap leaching methods. Heap leaching consists of stacking crushed, oxidized material on impermeable pads, where a weak cyanide solution is applied to the surface of the heap to dissolve and leach the gold and silver. The gold and silver-bearing solution is then collected and processed into doré bars.

Table of Contents

At Black Fox, mineralized material from the underground mine is transported to the mill site and fed to the mill’s crushing circuit. Following additional processing and refining, the operation produces doré bars.

At San José, mineralized material from the underground mine is processed at a mill site, producing a concentrate and doré product.

Hedging Activities

Our strategy is to provide shareholders with exposure to gold and silver prices by selling our gold and silver ounces at spot market prices and consequently, we do not hedge our gold or silver sales. We may, however, from time to time, manage certain risks associated with fluctuations in foreign currencies using the derivatives market.

Gold and Silver Reserves

We have established gold and/or silver reserves at three of our properties: Gold Bar, Black Fox and San José. In 2020, through consultations with field experts, we completed work around the Gold Bar mineral reserve to revise the previous estimate. The work included drilling and metallurgical testing, geological and structural modelling and a 110,500 feet (33,700 m) drill program. On January 7, 2021, we announced the updated Indicated Resource and Probable Reserve Estimates of the Gold Bar mine and subsequently filed the 43-101 Technical Report on February 22, 2021.

The following table summarizes the estimated portion of proven and probable gold and silver reserves attributable to us for the Gold Bar mine, the Black Fox mine and San José mine as of December 31, 2020:

(1) | The reserve estimate for the Black Fox mine as at December 31, 2020 was prepared by Channa Kumarage P.Eng., Senior Mine Planner and Patrick Lachapelle P.Eng., Technical Services Manager, and reviewed by Rory Greyvensteyn, General Manager, all employees of our company. The mineral reserves were estimated using a gold price of $1,650 per ounce. Reserves are stated at a mill feed reference point and include diluting materials and mining losses.

(2) | The reserve estimate for the Gold Bar mine as at December 31, 2020 was prepared by Joseph McNaughton, P.E., Senior Mining Engineers, Partner, Independent Mining Consultants and reviewed by Jeff Choquette and Todd Wakefield of Mine Technical Services Ltd. The reserves stated in the table above are contained within an engineered pit design between the $1,250/oz and $1,400 gold sales price Lerchs-Grossman pit shells.

(3) | The reserve estimate for the San José mine as at December 31, 2020, presented on a 49% basis, was prepared by Hochschild and audited by P&E Mining Consultants Inc. (“P&E”). The mineral reserves were estimated using metal prices of $1,800 per ounce of gold and $20 per ounce of silver. The reserves, as presented, are in place and include mining dilution and mining losses, but do not include allowances for mill or smelter recoveries. The reserve estimate for our 49% interest is based on that percentage of the 100% basis.

Competitive Business Conditions

We compete with many companies in the mining and mineral exploration and production industry, including large, established mining companies with substantial capabilities, personnel, and financial resources. There is a limited supply of desirable mineral lands available for claim-staking, lease, or acquisition in the United States, Canada, Mexico, or Argentina, and other areas where we may conduct our mining or exploration activities. We may be at a competitive disadvantage in acquiring mineral properties, since we compete with these individuals and companies, many of which have significantly greater financial resources and larger technical staffs than we do. From time to time, specific properties or areas which would otherwise be attractive to us for exploration or acquisition may be unavailable due to their previous acquisition by other companies or our lack of financial resources.

Table of Contents

Competition in the industry is not limited to the acquisition of mineral properties, but also extends to the technical expertise to find, advance, and operate such properties; the labor to operate the properties; and the capital for the purpose of funding such exploration and development. Many competitors not only explore for and mine precious and base metals but conduct refining and marketing operations on a world-wide basis. Such competition may result in not only our company being unable to acquire desired properties, but to recruit or retain qualified employees or to acquire the capital necessary to fund our operation and advance our properties. Our inability to compete with other companies for these resources would have a material adverse effect on our results of operation, financial condition and cash flows.

General Government Regulations

In the United States, Canada, Mexico and Argentina, we are subject to various governmental laws and regulations, including environmental regulations. Other than operating licenses for our mining and processing facilities and concessions granted under contracts with the host government, there are no third party patents, licenses or franchises material to our business. The applicable laws and regulations applicable to us include but are not limited to:

| ● | mineral concession rights;

| ● | surface rights;

| ● | water rights;

| ● | mining royalties;

| ● | environmental laws;

| ● | mining permits;

| ● | mining and income taxes;

| ● | health and safety laws and regulations;

| ● | labor laws and regulations; and

| ● | export regulations.

We believe that all of our properties are operated in compliance with all applicable governmental laws and regulations.

Reclamation Obligations

Under applicable laws in the jurisdictions where our properties are located, we are required to reclaim disturbances caused by our mining activities. Accordingly, we have recorded estimates in our financial statements for our reclamation obligations, in accordance with United States Generally Accepted Accounting Principles (“US GAAP” or “GAAP”) the most significant of which are related to our properties in the U.S., Canada and Mexico.

Estimated future reclamation costs are based primarily on legal and regulatory requirements. At December 31, 2020, we accrued $34.0 million for reclamation costs relating to currently developed and producing properties. These amounts are included in Asset Retirement Obligation on the Consolidated Balance Sheets.

U.S. Environmental Laws

We are subject to extensive environmental regulation under the laws of the U.S. and Nevada, the state where our U.S. operations are conducted. For example, certain mining wastes from the extraction and processing of ores would be considered hazardous waste under the Resource Conservation and Recovery Act (“RCRA”) and state law equivalents, but we are currently exempt from the extensive set of Environmental Protection Agency (“EPA”) regulations governing hazardous waste. If our mine wastes were treated as hazardous waste under RCRA or such wastes resulted in operations being designated as “Superfund” sites under the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”) or state law equivalents for cleanup, significant expenditures could be required for the construction of additional waste disposal facilities, for other remediation expenditures, or for natural resource damages. Under CERCLA, any present or past owners or operators of a Superfund site generally may be held liable and may be forced to undertake remedial cleanup action or to pay for the government’s cleanup efforts. Such owners or operators may also be liable to governmental entities for the cost of damages to natural resources, which may be substantial. Additional regulations or requirements may also be imposed upon our operations, tailings, and waste disposal areas, as well as upon mine closure under federal and state environmental laws and regulations, including, without limitation, CERCLA, the Clean Water Act, Clean Air Act, the Endangered Species Act and state law equivalents.

Table of Contents

We have reviewed and considered current federal legislation relating to climate change and do not believe it to have a material effect on our operations. Future changes in U.S. federal or state laws or regulations could have a material adverse effect upon us and our results of operations.

Foreign Government Regulations

Canada, where the Black Fox mine, Stock mill and other exploration and development projects are located, and Mexico, where the El Gallo Project and Fenix Project are located, have both adopted laws and guidelines for environmental permitting that are similar to those in effect in the U.S. The permitting process requires a thorough study to determine the baseline condition of the mining site and surrounding area, an environmental impact analysis, and proposed mitigation measures to minimize and offset the environmental impact of exploration and mining operation activities. We have received all permits required to operate our current activities in Canada and Mexico and have received all permits necessary for the exploration activities being conducted at our other non-U.S. properties.

Customers

Production from Gold Bar, Black Fox, and the El Gallo Project is sold as refined metal on the spot market or doré under the terms set out in doré purchase agreements.

We have doré purchase agreements with Canadian financial institutions, Asahi Refining (“Asahi”), our refiner, and with metals trading companies. Under the terms of our doré purchase agreements, we have the option to sell approximately 90% of the gold and silver contained in doré bars produced at Gold Bar, Black Fox and the El Gallo Project prior to the completion of refining. During the year ended December 31, 2020, 95% of our consolidated sales were made to The Bank of Nova Scotia and Asahi, with 34% of the sales made through the doré purchase agreement.

During the year ended December 31, 2020, 90% of total sales from the San José mine were made to three companies: Aurubis AG, a Germany company, accounted for 21% of that amount, Argo-Heraeus, a Swiss company, accounted for 21% of such amount and LS Nikko Copper Inc., a South Korean company, accounted for 48% of that amount. MSC has sales agreements with each of these purchasers.

In the event that our customer relationships or MSC’s customer relationships were interrupted for any reason, we believe that we or MSC could locate other purchasers for our products. However, any interruption may temporarily disrupt the sale of our products and may affect our operating results.

Human Capital Resources

As of December 31, 2020, we had 377 employees including 83 in the United States, 24 in Toronto, Ontario, Canada, 166 in Timmins, Ontario, Canada, 98 employees based in Mexico, and 6 in Argentina. All of our employees based in Toronto work in an executive, technical or administrative position, while our employees in the United States, Timmins, Mexico, and Argentina include management, laborers, craftsmen, mining, geology and environmental specialists, information technologists, and various other support roles. As of December 31, 2020, MSC had 1,431 employees in Argentina.

A portion of our employees in Mexico are covered by union labor contracts with whom we believe we have good relations. We also frequently engage independent contractors in connection with certain administrative matters and the exploration of our properties, such as drillers, geophysicists, geologists, and other specialty technical disciplines.

​

For Canada and United States, we also engage independent contractors for technical and professional expertise as well as extractive and exploration activities such as drilling, geophysics, hauling and crushing.

ITEM 1A. RISK FACTOR S

Our business activities and financial condition are subject to significant risks, including those described below. You should carefully consider these risks. If any of these risks actually occurs, our business, financial condition, and/or results of operation could be adversely affected. This report, including Management’s Discussion and Analysis of Financial Condition and Results of Operations, contains forward looking statements that may be affected by several risk factors, including those set forth below. The following information summarizes all material risks known to us as of the date of filing this report:

Table of Contents

Risks Relating to Our Financial Condition, Results of Operation and Cash Flows

Our results of operations, cash flows and the value of our properties are highly dependent on the market prices of gold, silver, and copper and these prices can be volatile.

The profitability of our gold and silver mining operations and the value of our mining properties are directly related to the market price of gold, silver and copper. The price of gold, silver and copper may also have a significant influence on the market price of our common stock. Historically, the market price of gold and silver has fluctuated significantly and is affected by numerous factors beyond our control. These factors include supply and demand fundamentals, global or national political or economic conditions, expectations with respect to the rate of inflation, the relative strength of the U.S. dollar and other currencies, interest rates, gold and silver sales and loans by central banks, forward sales by metal producers, accumulation and divestiture by exchange traded funds, and a number of other factors such as industrial and commercial demand. The volatility of mineral prices represents a substantial risk which no amount of planning or technical expertise can fully eliminate.

We derive all of our revenue from the sale of gold and silver and our results of operations will fluctuate as the prices of these metals change. A period of significant and sustained lower gold and silver prices would materially and adversely affect our results of operations and cash flows. In the event metal prices decline or remain low for prolonged periods of time, our existing producing properties may become uneconomic and we might be unable to develop our undeveloped properties, which may further adversely affect our results of operations, financial performance and cash flows. An asset impairment charge may also result from the occurrence of unexpected adverse events that impact our estimates of expected cash flows generated from our producing properties or the market value of our non-producing properties, including a material diminution in the price of gold and/or silver.

Our results of operations have been and could in the future be materially and adversely affected by the impairment of assets.

During 2020, the price of gold, as measured by the London PM fix, fluctuated between $1,474 and $2,067 per ounce, while the price of silver fluctuated between $12.00 and $28.90 per ounce. As at March 10, 2021, gold, silver and copper prices were $1,716 per ounce, $25.65 per ounce, and $4.01 per pound, respectively.

A material reduction in cash flow resulting from the revision of our mine plan and reserve estimate at the Gold Bar mine in Nevada has required reductions in certain operating expenditures for most of 2020 in order to preserve working capital. In light of the working capital reduction, the Company completed 4 equity raises: September 10, 2020, December 31, 2020, January 29, 2021, and February 9, 2021 for gross proceeds of $64.4 million. It also renegotiated its debt facility in 2020 to more favorable repayment terms.

​

We initially established reserves at Gold Bar as of December 31, 2017, and such estimate was updated as of December 31, 2018. As of the date of filing this report, the further updated reserve estimate for the Gold Bar mine was completed and updated report filed on February 22, 2021. The operations are now fully funded including the Company’s newest Froome development project at its Fox Complex in Canada which is expected to reach commercial production in late Q4 of this year.

​

We have incurred substantial losses in recent years and may never return to profitability.

During the three years ended December 31, 2020, we have incurred pre-tax losses on an annual basis of $153.7 million, $63.6 million and $47.6 million. As of December 31, 2020, our accumulated deficit, which includes non-cash impairment charges, was $1.2 billion. In the future, our ability to become profitable will depend on the profitability of the Gold Bar, Black Fox and San José mines, our ability to bring the Froome project into production and generate revenue sufficient to cover our costs and expenses, and our ability to advance, sell or otherwise monetize our other properties, including the Los Azules copper project. In pursuit of that objective, we will seek to identify additional mineralization that can be extracted economically at operating and exploration properties. For our non-operating properties that we believe demonstrate economic potential, we need to either develop our properties, locate and enter into agreements with third party operators, or sell the properties. We may suffer significant additional losses in the future and may not be profitable again. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis.

Table of Contents

Our business requires substantial capital investment and we may be unable to raise additional funding on favorable terms to develop additional mining operations. In addition, our continued reliance on equity funding will result in continued dilution to our existing shareholders.

We have in the past and will likely in the future require significant capital to develop our exploration projects. A significant portion of that funding in the past has come in the form of sales of our common stock. We continue to evaluate capital and development expenditure requirements as well as other options to monetize certain assets in the Company’s portfolio including Los Azules, Grey Fox, Stock and the Fenix Project. If we make a positive decision to develop one or more of these initiatives, the expenditures incurred may significantly exceed our working capital. Our ability to obtain necessary funding, in turn, depends upon a number of factors, including the state of the economy, our operating results and applicable commodity prices. We may not be successful in obtaining the required financing to advance our projects or other purposes, on terms that are favorable to us or at all, in which case, our ability to replace reserves and continue operating would be adversely affected. Failure to obtain such additional financing could result in delay or indefinite postponement of further exploration or potential development and the possible partial or total loss of our interest in certain properties. Even if we are successful in obtaining additional equity capital, it will result in dilution to existing shareholders.

Our indebtedness adversely affects our cash flow and may adversely affect our ability to operate our business.

As of December 31, 2020, we had an outstanding long term, secured debt with a principal amount of $50.0 million. Repayment of the loan is secured by a lien on certain of our and our subsidiaries’ assets. This debt requires us to make monthly interest payments and, beginning in August 2022, to begin making monthly principal payments of $2 million for 12 months and a final $26 million payment on August 31, 2023.We cannot be certain that our cash flow from operations will be sufficient to allow us to pay the principal and interest on our debt and meet our other obligations. Even if we have sufficient cash flow to retire the debt, those payments will affect the amount of cash we have available to invest in capital investment, exploration, ongoing operations and other purposes. Payments on our debt may also inhibit our ability to react to changing business conditions.

Any failure to meet our debt obligations could harm our business and financial condition and may require us to sell assets or take other steps to satisfy the debt.

Our ability to make payments on and/or to refinance our indebtedness and to fund planned capital expenditures will depend on our ability to generate sufficient cash flow from operations in the future. We cannot assure that our business will generate sufficient cash flow from operations or that future borrowings will be available to us in an amount sufficient to enable us to pay principal and interest on our indebtedness or to fund our other liquidity needs. Decreases in precious metal prices, in addition to our ability to execute our mine plans at existing operations, may adversely affect our ability to generate cash flow from operations. If our cash flow and existing capital resources are insufficient to fund our debt obligations, we may be forced to reduce our planned capital expenditures, sell assets, seek additional equity or debt capital, or restructure our debt, and any of these actions, if completed, could adversely affect our business and/or the holders of our securities. We cannot assure you that any of these remedies could, if necessary, be completed on commercially reasonable terms, in a timely manner or at all. In addition, any failure to make scheduled payments of interest and principal on our outstanding indebtedness could result in the immediate acceleration of the debt and foreclosure of our assets.

Restrictive debt covenants could limit our growth and our ability to finance our operations, fund our capital needs, respond to changing conditions, and engage in other business activities that may be in our best interests.

Our credit facility contains covenants that restrict or limit our ability to:

| ● | Pay dividends or distributions on our capital stock;

| ● | Borrow additional funds;

| ● | Repurchase, redeem, or retire our capital stock;

| ● | Make certain loans and investments;

| ● | Sell assets;

| ● | Enter into certain transactions with affiliates;

| ● | Create or assume certain liens on our assets;

| ● | Make certain acquisitions; or

| ● | Engage in certain other corporate activities.

Table of Contents

As part of our facility, the debt can be called in certain circumstances, including on demand in the event of a material adverse change in our business or our inability to satisfy certain financial tests on an ongoing basis. Our ability to comply with these requirements may be affected by events beyond our control, and we cannot assure you that we will satisfy them in the future. In addition, these requirements could limit our ability to obtain future financings, make needed capital expenditures, withstand a future downturn in our business or the economy in general, or otherwise conduct necessary corporate activities. We may also be prevented from taking advantage of potential business opportunities that arise because of the restrictive covenants under our debt agreement. A breach of any of the covenants in our debt agreements could result in a default under the agreement.

Increased operating and capital costs could affect our results of operations.

Costs at any particular mining location are subject to variation due to a number of factors, such as variable ore grade, changing metallurgy and revisions to mine plans in response to the physical shape and location of the ore body, as well as the age and utilization rates for the mining and processing- related facilities and equipment. In addition, costs are affected by the price and availability of input commodities, such as fuel, electricity, labor, chemical reagents, explosives, steel, concrete and mining and processing related equipment and facilities. Commodity costs are, at times, subject to volatile price movements, including increases that could make production at certain operations less profitable. Further, changes in laws and regulations can affect commodity prices, uses and transport. Reported costs may also be affected by changes in accounting standards. A material increase in costs at any significant location could have a significant effect on our results of operation and operating cash flow.

We could have significant increases in capital and operating costs over the next several years in connection with the development of new projects in challenging jurisdictions and in the sustaining and/or expansion of existing mining and processing operations. Costs associated with capital expenditures may increase in the future as a result of factors beyond our control. Increased capital expenditures may have an adverse effect on the results of operation and cash flow generated from existing operations, as well as the economic returns anticipated from new projects.

If we do not hedge our exposure to reductions in gold and silver prices, we may be subject to significant reductions in price.

We do not use hedging transactions with respect to any of our gold and silver production and we do not expect to do so in the future. Accordingly, we may be exposed to more significant price fluctuations if gold and/or silver prices decline. While the use of hedging transactions limits the downside risk of price declines, their use also may limit future revenues from price increases. Hedging transactions also involve the risk that the counterparty may be unable to satisfy its obligations.

Estimates relating to new development projects and mine plans of existing operations are uncertain and we may incur higher costs and lower economic returns than estimated.

Our decision to develop a project is typically based on the results of feasibility studies, which estimate the anticipated economic returns of a project. However, the actual project profitability or economic feasibility may differ from such estimates as a result of any of the following factors, among others:

| ● | Changes in tonnage, grades and metallurgical characteristics of mineralized material to be mined and processed;

| ● | Changes in input commodity and labor costs;

| ● | The quality of the data on which engineering assumptions were made;

| ● | Adverse geotechnical conditions;

| ● | Availability of an adequate and skilled labor force;

| ● | Availability, supply and cost of utilities such as water and power;

| ● | Fluctuations in inflation and currency exchange rates;

| ● | Changes in metals prices; or

| ● | Changes in tax laws, the laws and/or regulations around royalties and other taxes due to the regional and national governments and royalty agreements.

​ |  |  |

Our recent development activities, including Gold Bar and Black Fox, may not result in the expansion or replacement of past production with new production, or one or more of these new production sites or facilities may be less profitable than

Table of Contents

currently anticipated or may not be profitable at all, any of which could have a material adverse effect on our results of operations and financial position.

For our existing operations, we base our mine plans on geological, metallurgical and engineering assumptions, financial projections and commodity price estimates. These estimates are periodically updated to reflect changes in our operations, including modifications to our proven and probable reserves and mineralized material, revisions to environmental obligations, changes in legislation and/or our political or economic environment, and other significant events associated with mining operations. There are numerous uncertainties inherent in estimating quantities and qualities of gold, silver and copper and costs to mine recoverable reserves, including many factors beyond our control, that could cause actual results to differ materially from expected financial and operating results or result in future impairment charges.

We are subject to foreign currency risks which may increase our costs and affect our results of operation.

While we transact most of our business in U.S. dollars, certain expenses, such as labor, operating supplies, and property and equipment, may be denominated in Canadian dollars, Mexican pesos or Argentine pesos. As a result, currency exchange fluctuations may impact our operating costs. The appreciation of non-U.S. dollar currencies against the U.S. dollar increases costs and the cost of purchasing property and equipment in U.S. dollar terms in Canada, Mexico and Argentina, which can adversely impact our operating results and cash flows.

The value of cash and cash equivalents denominated in foreign currencies also fluctuates with changes in currency exchange rates. Appreciation of non-U.S. dollar currencies results in a foreign currency gain on such investments and a depreciation in non-U.S. dollar currencies results in a loss. We have not utilized market risk sensitive instruments to manage our exposure to foreign currency exchange rates but may in the future actively manage our exposure to foreign currency exchange rate risk. We also hold portions of our cash reserves in Canadian, Mexican and Argentine currency.

Our continuing reclamation obligations at Tonkin, Gold Bar, Black Fox and other Timmins properties, El Gallo, and other properties could require significant additional expenditures.

We are responsible for the reclamation obligations related to disturbances on all our properties. In Canada and the United States, we are required to post bonds to ensure performance of our reclamation obligations. As of December 31, 2020, we have accrued $34.0 million in estimated reclamation costs for our properties, including $31.8 million covered by surety bonds for projects in the United States and Canada. We have not posted a bond in Mexico as none is required by the current legislation; however, we have recorded a liability based on the estimated amount of our reclamation obligations in that jurisdiction.

There is a risk that any surety bond or recorded liability, even if increased based on the analysis and work performed to update the reclamation obligations, could be inadequate to cover the actual costs of reclamation when actually carried out. The satisfaction of bonding requirements and continuing reclamation obligations will require a significant amount of capital. Further, it is possible that the United States Bureau of Land Management (“BLM”) may request that we provide additional long-term financing supported by a long-term trust for an amount that cannot be determined at present. There is a risk that we will be unable to fund any additional bonding requirements or that the surety bonds may no longer be accepted by the governmental agencies as satisfactory reclamation coverage, in which case we would be required to replace the surety bonding with cash, and further, that the regulatory authorities may increase reclamation and bonding requirements to such a degree that it would not be commercially reasonable to continue exploration activities, which may adversely affect our results of operations, financial performance and cash flows.

There is no guarantee that we will declare distributions to shareholders.

From June 2015 to September 2018, we paid a distribution to holders of our common stock on a semi-annual basis. Those distributions were suspended in March 2019. Any determination to reinstate this distribution on our common stock will be based primarily upon covenants in outstanding debt instruments, our financial condition, results of operations and capital requirements, including for capital expenditures and acquisitions, and our Board of Directors’ determination that the distribution to shareholders is in the best interest of our shareholders and in compliance with all laws and agreements applicable to the Company.

Risks Relating to our Operation as a Mining Company

Our estimates of proven and probable reserves and mineralized material are based on interpretation and assumptions and may yield less mineral production under actual conditions than is currently estimated or result in additional impairment charges to our operations.

Unless otherwise disclosed proven and probable reserves and mineralization figures presented in our filings with securities regulatory authorities, including the SEC, news releases and other public statements that may be made from time to time, are based upon estimates made by both independent and our own internal professionals. Estimates of proven and probable reserves and mineralized material are subject to considerable uncertainty and are based, to a large extent, on the prices of gold and silver and interpretations of geologic data obtained from drill holes and other exploration techniques. These prices and interpretations are subject to change. If we determine that certain of our estimated reserves or mineralized material have become uneconomic, we may be forced to reduce our estimates. Actual production may be significantly less than we expect and such reductions may result in impairment charges such as we experienced in 2020.

When making determinations about whether to advance any of our projects to development, we rely upon such estimated calculations as to the mineralized material and grades of mineralization on our properties. Until ore is mined and processed, mineralized material and grades of mineralization must be considered as estimates only. We cannot ensure that these estimates will be accurate, or this mineralization can be mined or processed profitably.

Any material changes in mineral estimates and grades of mineralization may affect the economic viability of placing a property into production and such property’s return on capital. There can be no assurance that minerals recovered in small scale tests will be recovered in large-scale tests under on-site conditions or in production scale. Extended declines in market prices for gold and/or silver may render portions of our mineralization estimates uneconomic and result in reduced reported mineralization or adversely affect the commercial viability of one or more of our properties. Any material reductions in estimates of mineralization, or of our ability to extract this mineralization, could have a material adverse effect on our results of operations or financial condition.

Investors should also be aware that calculations of “reserves” differ under SEC reporting standards and those under other international standards, such as Canada. Investors should also be aware that mineralized material may never be converted into reserves. Please also see, CAUTIONARY NOTE TO UNITED STATES INVESTORS-INFORMATION CONCERNING PREPARATION OF RESOURCE AND RESERVE ESTIMATES.

We may be unable to replace gold and silver reserves as they become depleted.

Like all metal producers, we must continually replace reserves depleted by production to maintain production levels over the long term and provide a return on invested capital. Depleted reserves can be replaced in several ways, including expanding known ore bodies, by locating new deposits or acquiring interests in reserves from third parties. Exploration is highly speculative in nature, involves many risks and uncertainties and is frequently unsuccessful in discovering significant mineralization. Accordingly, our current or future exploration programs may not result in new mineral producing operations. Even if significant mineralization is discovered, it will likely take many years from the initial phases of exploration until commencement of production, during which time the economic feasibility of production may change.

From time to time, we may acquire ore reserves from other parties, as we did in 2017. Such acquisitions are based on an analysis of a variety of factors including historical operating results, estimates of and assumptions regarding the extent of ore reserves, the timing of production from such reserves and cash and other operating costs. In addition, we may rely on data and reports prepared by third parties (including the ability to permit and comply with existing regulations) and which may contain information or data that we are unable to independently verify or confirm in advance. Other than historical operating results, all of these factors are uncertain and may have an impact on our revenue, our cash flow and other operating issues, as well as contributing to the uncertainties related to the process used to estimate ore reserves.

As a result of these uncertainties, our exploration programs and acquisitions may not result in the expansion or replacement of our current production with new ore reserves or operations, which could have a material adverse effect on our business, prospects, results of operations and financial position.

Our acquisitions may not achieve their intended results.

Our acquisitions subject us to many risks. The Fox Complex acquired in 2017 was a distressed asset which has struggled to produce positive cash flows during its years of operation. We are working to improve the operations but with a small

reserve base, the success of this operation is dependent upon finding additional mineralization through exploration and there is no guarantee that we will be able to convert this mineralization into mineable reserves. We may discover title defects or adverse environmental or other conditions relating to the properties acquired in the transactions of which we are currently unaware. Environmental, title, and other problems could reduce the value of the properties to us, and, depending on the circumstances, we could have limited or no recourse to the sellers with respect to those problems. We have assumed substantially all of the liabilities associated with acquired properties and would be entitled to indemnification in connection with those liabilities in only limited circumstances, for limited periods and in limited amounts. Potential remedies may not be adequate to cover any liabilities we incur, and such liabilities could be significant.

We own our 49% interest in the San José mine under the terms of an option and joint venture agreement (“OJVA”), and therefore we are unable to control all aspects of the exploration and development of, and production from, this property.

Our interest in the San José mine is subject to the risks normally associated with the conduct of joint ventures. A disagreement between joint venture partners on strategic decisions or how to conduct business efficiently, the inability of joint venture partners to meet their obligations to the joint venture or third parties, or litigation arising between joint venture partners regarding joint venture matters could have a material adverse effect on the viability of our interests held through the joint venture. Since all day-to-day decisions are made by the majority owner of the venture, we are unable to participate in those decisions, including whether and when to pay dividends to the venture partners.

Even if we are successful in achieving one or more of our strategic initiatives at the project, development at Los Azules presents development challenges that may negatively affect, if not completely negate, the feasibility of development of the property.

The Los Azules property is located in a remote location that is currently accessed by 75 miles of dirt road with eight river crossings and two mountain passes above 13,451 feet. Even assuming that technical difficulties associated with this remote location can be overcome, the significant capital costs required to develop the project may make the project uneconomical. If the long term price of copper were to decrease significantly below the current price or capital cost estimates increase significantly, Los Azules may not be feasible for development, and we may have to write-off the remaining carrying value of the asset. Furthermore, the project’s economic feasibility has not yet been demonstrated through a full feasibility study. The Preliminary Economic Assessment (“PEA”) is preliminary in nature, includes NI 43-101 mineral resources that are considered too speculative geologically to have economic considerations applied to them that would allow them to be categorized as mineral reserves either under Guide 7 or NI 43-101, and there is no certainty that the PEA will be realized.

We may acquire additional exploration-stage properties on which reserves may never be discovered.

We have in the past and may in the future acquire additional exploration-stage properties. There can be no assurance that we have or will be able to complete the acquisition of such properties at reasonable prices or on favorable terms and that reserves will be identified on any properties that we acquire. We may also experience negative reactions from the financial markets if we are unable to successfully complete acquisitions of additional properties or if reserves are not located on acquired properties. These factors may adversely affect the trading price of our common stock or our financial condition or results of operations.

The nature of mineral exploration and production activities involves a high degree of risk and the possibility of uninsured losses that could materially and adversely affect our operations.

Exploration for and production of minerals is highly speculative and involves greater risk than many other businesses. Many exploration programs do not result in the discovery of mineralization, and any mineralization discovered may not be of sufficient quantity or quality to be profitably mined. Few properties that are explored are ultimately advanced to production. Our current exploration efforts are, and future development and mining operations we conduct will be, subject to all of the operating hazards and risks normally incident to exploring for and developing mineral properties, such as, but not limited to:

| ● | economically insufficient mineralized material;

| ● | fluctuations in production costs that may make mining uneconomical;

| ● | availability of labor, contractors, engineers, power, transportation and infrastructure;

| ● | labor disputes;

| ● | potential delays related to social, public health, and community issues;

13

Table of Contents

| ● | negotiations with aboriginal groups or local populations affecting our efforts to explore, develop or produce gold and silver deposits;

| ● | unanticipated variations in grade and other geological problems;

| ● | environmental hazards;

| ● | water conditions;

| ● | difficult surface or underground conditions;

| ● | metallurgical and other processing problems;

| ● | mechanical and equipment performance problems;

| ● | industrial accidents, personal injury, fire, flooding, cave-ins, landslides and other natural disasters; and

| ● | decrease in reserves or mineralized material due to a lower silver, gold or copper price.

Any of these risks can materially and adversely affect, among other things, the development of properties, production quantities and rates, costs and expenditures, potential revenues and production dates. We currently have no insurance to guard against any of these risks, except in very limited circumstances. If we determine that capitalized costs associated with any of our mineral interests are not likely to be recovered, we would incur a write-down of our investment in these interests. All of these factors may result in losses in relation to amounts spent would then not be recoverable.

Our operations are subject to permitting requirements which could require us to delay, suspend or terminate our operations on our mining properties.

Our mining operations, including ongoing exploration drilling programs and development efforts, require permits from various state and federal governments, including permits for the use of water and for drilling wells for water. We may be unable to obtain these permits in a timely manner, on reasonable terms or on terms that provide us sufficient resources to develop our properties, or at all. Even if we are able to obtain such permits, the time required by the permitting process can be significant. If we cannot obtain or maintain the necessary permits, or if there is a delay in receiving these permits, our timetable and business plan for exploration of our properties will be adversely affected, which may in turn adversely affect our results of operations, financial condition, cash flows and market price of our securities.

Due to an increased level of non-governmental organization and aboriginal and local group activity targeting the mining industry, the potential for the government or process instituted by non-governmental organizations, aboriginal and local, to delay the issuance of permits or impose new requirements or conditions upon mining operations may be increased. Any changes in government policies may be costly to comply with and may delay mining operations. Future changes in such laws and regulations, if any, may adversely affect our operations, make our operations prohibitively expensive, or prohibit them altogether. If our interests are materially adversely affected as a result of a violation of applicable laws, regulations, or permitting requirements or a change in applicable law or regulations, it would have a significant negative impact on the value of our company and could have a significant impact on our stock price.

Our operations in Argentina and Mexico are subject to political and social risks.

With respect to our affiliated company, Minera Santa Cruz S.A (“MSC”) which owns the San José mine, there are risks relating to an uncertain or unpredictable political and economic environment in Argentina, illustrated by the following:

| ● | Argentina defaulted on foreign debt repayments and on the repayment on a number of official loans to multinational organizations in 2002 and 2003, and defaulted again on its bonds in 2014.

| ● | In 2012, Argentina’s President announced the nationalization of the majority stake of Yacimientos Petrolíferos Fiscales (YPF), Argentina’s largest oil company.

| ● | In December 2017, Argentina enacted comprehensive tax reform (Law No. 27,430 (the “Law”)). Specifically, the Law introduces amendments to tax and other various laws, including a special regime comprising an optional revaluation of assets for income tax purposes. The Law gradually reduces the corporate tax rate from 35% to 25% over the period of 2018 to 2020.

| ● | In 2018, Argentina’s federal government introduced a decree imposing a temporary tax on all exports from Argentina. The tax was introduced as an emergency measure due to the significant peso devaluation during the year. The estimated impact to MSC is a tax of approximately 7.5% of revenue.

| ● | In September 2019, Argentine authorities implemented new foreign exchange regulations which impact the results of MSC. The main restrictions include, but are not limited to, full repatriation of proceeds of exports in cash and bank savings to be denominated only in Argentine pesos and authorization from Argentina Central Bank being required for dividend distributions abroad and intercompany loan payments.

| ● | In October 2019, Alberto Fernández and former president Cristina Fernández de Kirchner were elected to office. The prior president, Mr. Mauricio Macri, who assumed office in December 2015, implemented several significant economic and policy reforms, including reforms related to foreign exchange and trade, fiscal policy, labor laws and tax rules. The fiscal, monetary and currency adjustments undertaken by the Macri administration subdued growth in the short-term, and some measures, including the export tax, have negatively impacted Argentina sourced revenues. There remains uncertainty about changes that may be adopted by the new administration and their impact on the Argentina economy and our business.

| ● | In December 2019, the Argentina federal government approved a decree delaying the corporate tax rate to change from 30% to 25% to the end of 2021 and extending the temporary export tax introduced in September 2018 to the end of 2021. Furthermore, the decree suspended the increase in the dividend withholding tax from 7% to 13% until January 2021.

| ● | In 2020, the Alberto Fernández administration marked its first year in office, a year in which it faced numerous challenges including renegotiating Argentina’s foreign debt, managing currency crises, and, most difficult, designing Argentina’s response to the COVID-19 pandemic.

​

With respect to the El Gallo Project in Mexico, there has been an ongoing level of violence and crime relating to drug cartels and gangs in Sinaloa State where we operate, and in other regions of Mexico. Our facility at the El Gallo Project was robbed in 2015. On December 17, 2019, the US State Department issued a Level 2 (“increased caution”) warning with respect to five Mexican states, including Sinaloa State, due to violent crime. These events may disrupt our ability to carry out exploration and mining activities and affect the safety and security of our employees and contractors. On September 8, 2020, the US State Department issued a Level 3 (“Reconsider travel”) revaluating travel to Mexico with respect to COVID-19 and warning travel to five Mexican states, including Sinaloa State, due to violent crime. These events may disrupt our ability to carry out exploration and mining activities and affect the safety and security of our employees and contractors.

Our operations and properties in Canada expose us to additional political risks.

Our properties in Canada may be of particular interest or sensitivity to one or more interest groups, including aboriginal groups (which are generally referred to as "First Nations" and “Metis” groups). We have mineral projects in Ontario that are in areas with an aboriginal presence. It is our practice to work closely with and consult with First Nations in areas in which our projects are located or which could be impacted by our activities. However, there is no assurance that relationships with such groups will be positive. Accordingly, it is possible that our production, exploration or development activities on these properties could be interrupted or otherwise adversely affected in the future by political uncertainty, native land claims entitlements, expropriations of property, changes in applicable law, governmental policies and policies of relevant interest groups, including those of First Nations. Any changes in law or relations or shifts in political conditions may be beyond our control, or we may enter into agreements with First Nations, all of which may adversely affect our business and operations and if significant, may result in the impairment or loss of mineral concessions or other mineral rights, or may make it impossible to continue our mineral production, exploration or development activities in the applicable area, any of which could have an adverse effect on our financial conditions and results of operations.

Our operations face substantial regulation of health and safety.

​

Our operations are subject to extensive and complex laws and regulations governing worker health and safety across our projects and our failure to comply with applicable legal requirements can result in substantial penalties. Future changes in applicable laws, regulations, permits and approvals or changes in their enforcement or regulatory interpretation could substantially increase costs to achieve compliance, lead to the revocation of existing or future exploration or mining rights or otherwise have an adverse impact on our results of operations and financial position.

​

Our mines are inspected on a regular basis by government regulators who may issue citations and orders when they believe a violation has occurred under local mining regulations. If inspections result in an alleged violation, we may be subject to fines, penalties or sanctions and our mining operations could be subject to temporary or extended closures.

​

In addition to potential government restrictions and regulatory fines, penalties or sanctions, our ability to operate (including the effect of any impact on our workforce) and thus, our results of operations and our financial position (including because of potential related fines and sanctions), could be adversely affected by accidents, injuries, fatalities or events detrimental (or perceived to be detrimental) to the health and safety of our employees, the environment or the communities in which we operate.

Reform of the General Mining Law in the United States could adversely affect our results of operations.

​

Periodically, members of the U.S. Congress have introduced bills which would supplant or alter the provisions of the General Mining Law of 1872, which governs the unpatented claims that we control with respect to our U.S. properties. One such amendment has become law and has imposed a moratorium on the patenting of mining claims, which reduced the security of title provided by unpatented claims such as those on our U.S. properties. If additional legislation is enacted, it could substantially increase the cost of holding unpatented mining claims by requiring payment of royalties, and could significantly impair our ability to develop mineral estimates on unpatented mining claims. Such bills have proposed, among other things, to make permanent the patent moratorium, to impose a federal royalty on production from unpatented mining claims and to declare certain lands as unsuitable for mining. Although it is impossible to predict at this time what royalties may be imposed in the future, the imposition of such royalties could adversely affect the potential for development of such mining claims, and the economics of existing operating mines on federal unpatented mining claims. Passage of such legislation could adversely affect our business.

Title to mineral properties can be uncertain, and we may be at risk of loss of ownership of one or more of our properties.

Our ability to explore and operate our properties depends on the validity of our title to that property. Our U.S. mineral properties include leases of unpatented mining claims, as well as unpatented mining and mill site claims, which we control directly. Unpatented mining claims provide only possessory title and their validity is often subject to contest by third parties or the federal government, which makes the validity of unpatented mining claims uncertain and generally riskier. Similarly, Canadian mineral properties consist of patented and unpatented claims which each have their respective risks and uncertainties. Further, there may be title defects or additional rights which are not recorded on the title. Our concessions in Mexico are subject to continuing government regulation and failure to adhere to such regulations will result in termination of the concession. Similarly, under Argentine Law, failure to comply with applicable conditions may result in the termination of the concession. Uncertainties inherent in mineral properties relate to such things as the sufficiency of mineral discovery, proper posting and marking of boundaries, assessment work and possible conflicts with other claims not determinable from public record. We have not obtained title opinions covering our entire property, with the attendant risk that title to some claims, particularly title to undeveloped property, may be defective. There may be valid challenges to the title to our property which, if successful, could impair development and/or operations.

We cannot ensure that we will have an adequate supply of water to complete desired exploration or development of our mining properties.

Our mining operations require significant quantities of water for mining, ore processing and related support facilities. Our operations in the United States, Mexico and Argentina are in areas where water is scarce and competition among users for continuing access to water is significant. Continuous production at our mines is dependent on our ability to maintain our water rights and claims and to defeat claims adverse to our current water uses in legal proceedings. Although each of our operations currently has sufficient water rights and claims to cover its operational demands, we cannot predict the potential outcome of pending or future legal proceedings relating to our water rights, claims and uses. Water shortages may also result from weather or environmental and climate impacts out of the Company’s control.

Our ongoing operations and past mining activities are subject to environmental risks, which could expose us to significant liability and delay, suspension or termination of our operations.

All aspects of our operations are subject to United States, Canada, Mexico and Argentina federal, state and local environmental regulation. These regulations mandate, among other things, the maintenance of air and water quality standards and land reclamation. They also set forth limitations on the generation, transportation, storage and disposal of solid and hazardous waste, including cyanide. Environmental legislation is evolving in a manner which will require stricter standards and enforcement, increased fines and penalties for non-compliance, more stringent environmental assessments of proposed projects, and a heightened degree of responsibility for us and our officers, directors and employees. Future changes in environmental regulation, if any, may adversely affect our operations, make our operations prohibitively expensive, or prohibit them altogether. Environmental hazards may exist on our properties that are unknown to us at the present and that have been caused by us, or previous owners or operators, or that may have occurred naturally. We utilize explosives in our business, which could cause injury to our personnel, and damage to our equipment or assets. Mining properties from the companies we have acquired may cause us to be liable for remediating any damage that those companies may have caused. The liability could include response costs for removing or remediating the release and damage to natural resources, including ground water, as well as the payment of fines and penalties. Failure to comply with applicable environmental laws, regulations and permitting requirements may also 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.

Our industry is highly competitive, attractive mineral lands are scarce, and we may not be able to obtain quality properties.

We compete with many companies in the mining industry, including large, established mining companies with substantial capabilities, personnel and financial resources. There is a limited supply of desirable mineral lands available for claim staking, lease or acquisition in the United States, Canada, Mexico and Argentina, and other areas where we may conduct exploration activities. We may be at a competitive disadvantage in acquiring mineral properties, since we compete with these individuals and companies, many of which have greater financial resources and larger technical staffs than we do. From time to time, specific properties or areas which would otherwise be attractive to us for exploration or acquisition may be unavailable to us due to their previous acquisition by other companies or our lack of financial resources. Competition in the industry is not limited to the acquisition of mineral properties but also extends to the technical expertise to find, advance, and operate such properties; the labor to operate the properties; and the capital for the purpose of funding such properties. Many competitors not only explore for and mine precious metals, but conduct refining and marketing operations on a world-wide basis. Such competition may result in our Company being unable not only to acquire desired properties, but to recruit or retain qualified employees or to acquire the capital necessary to fund our operation and advance our properties. Our inability to compete with other companies for these resources would have a material adverse effect on our results of operation, financial condition and cash flows.

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

A portion of our operations and construction projects are currently conducted in whole or in part by contractors, including specifically our operations at the Gold Bar and Black Fox mines. As a result, our operations are subject to a number of risks, some of which are outside our control, including:

| ● | Negotiating agreements with contractors on acceptable terms;

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

| ● | Reduced control and oversight over those aspects of operations which are the responsibility of the contractor;

| ● | Failure of a contractor to perform under its agreement;

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

| ● | Failure of a contractor to comply with our standards and policies, as well as with applicable legal and regulatory requirements, to the extent it is responsible for such compliance; and

| ● | Problems of a contractor with managing its workforce, labor unrest or other related employment issues.

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

If our employees or contractors engage in a strike, work stoppage or other slowdown, we could experience business disruptions and/or increased costs.

As of December 31, 2020, a number of our employees were represented by different trade unions and work councils which subject us to employment arrangements very similar to collective bargaining agreements. Further, most of our employees are based in foreign locations. The laws of certain foreign countries may place restrictions on our ability to take certain employee-related actions or require that we conduct additional negotiations with trade unions, works councils or other governmental authorities before we can take such actions.

If the employees or contractors at the Gold Bar, Mexico, or San José mines were to engage in a strike, work stoppage, or other slowdown in the future, we could experience a significant disruption of our operations. Such disruption could interfere with our business operations and could lead to decreased productivity, increased labor costs, and lost revenue.

We may not be successful in negotiating new collective bargaining agreements or other employment arrangements when the current ones expire. Furthermore, future labor negotiations could result in significant increases in our labor costs. The occurrence of any of the foregoing could have a material adverse effect on our business, financial condition, and results of operations.

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

Producing gold is an energy-intensive business, resulting in a significant carbon footprint. We utilize electricity, diesel fuel, gasoline, and natural gas to produce metal.

A number of governments or governmental bodies have introduced or are contemplating regulatory changes in response to the potential impacts of climate change that are viewed as the result of emissions from the combustion of carbon-based fuels. At the 21st Conference of the Parties of the United Nations Framework Convention on Climate Change (“UNFCC”) held in Paris in 2015, the Paris Agreement was adopted which was intended to govern emission reductions beyond 2020. The Paris Agreement went into effect in November 2016 when countries that produce at least 55% of the world's greenhouse gas emissions ratified the agreement. While there are no immediate impacts to business from the Paris Agreement, the goal of limiting global warming to “well below 2o C” will be taken up at national levels.

Some of the countries in which we operate have implemented, and are developing, laws and regulations related to climate change and greenhouse gas emissions. In December 2009, the United States Environmental Protection Agency (“EPA”) issued an endangerment finding under the U.S. Clean Air Act that current and projected concentrations of certain mixed greenhouse gases, including carbon dioxide, in the atmosphere threaten the public health and welfare. Additionally, the United States and China signed a bilateral agreement in November 2014 that committed the United States to reduce greenhouse gas emissions by an additional 26% to 28% below 2005 levels by the year 2025. The EPA in August 2015 issued final rules for the Clean Power Plan under Section 111 (d) of the Clean Air Act designed to reduce greenhouse gas emissions at electric utilities in line with reductions planned for the compliance with the Paris Agreement. On June 19, 2019, the EPA as part of a regulatory review repealed the Clean Power Plan and replaced it with the Affordable Clean Energy rule which eliminates most of the emission reduction standards included in the Clean Power Plan. That rule is now the subject of challenges in the courts.

Legislation and increased regulation and requirements regarding climate change could impose increased costs on us, our venture partners and our suppliers, including increased energy, capital equipment, environmental monitoring and reporting and other costs to comply with such regulations.

Risks Relating to Our Common Stock

A small number of existing shareholders own a significant portion of McEwen Mining common stock, which could limit your ability to influence the outcome of any shareholder vote.

As of March 10, 2021, Mr. McEwen beneficially owned approximately 18% of the 459.2 million shares of McEwen Mining common stock outstanding. Under our Articles of Incorporation and the laws of the State of Colorado, the vote of the holders of a majority of the shares voting at a meeting at which a quorum is present is generally required to approve most shareholder action. As a result, Mr. McEwen will be able to significantly influence the outcome of shareholder votes for the foreseeable future, including votes concerning the election of directors, amendments to our Articles of Incorporation or proposed mergers, acquisitions or other significant corporate transactions.

Our stock price may be volatile, and as a result you could lose all or part of your investment.

In addition to other risk factors identified herein and to volatility associated with equity securities in general, the value of your investment could decline due to the impact of any of the following factors upon the market price of our common stock:

| ● | Changes in the worldwide price for gold, silver and/or copper;

| ● | Disappointing results from our exploration or production efforts;

| ● | Producing at rates lower than those targeted;

| ● | Political and regulatory risks;

| ● | Weather conditions, including both unusually heavy rains and unusually light rains or drought;

| ● | Failure to meet our revenue or profit goals or operating budget;

| ● | Decline in demand for our common stock;

| ● | Downward revisions in securities analysts’ estimates or changes in general market conditions;

| ● | Technological innovations by competitors or in competing technologies;

| ● | Investor perception of our industry or our prospects;

| ● | Disruption of supply and demand and other economic factors due to virus and other disease;

| ● | Actions by government central banks; and

| ● | General economic trends.

Stock markets in general have in the past and may in the future experience extreme price and volume fluctuations. These fluctuations are often unrelated to operating performance and may adversely affect the market price of our common stock. Adverse price fluctuations may lead to threatened or actual delisting of our common stock from the NYSE. As a result, you may be unable to resell your shares at a desired price.

The future issuances of our common stock will dilute current shareholders and may reduce the market price of our common stock.

Under certain circumstances, our board of directors has the authority to authorize the offer and sale of additional securities without the vote of or notice to existing shareholders. We may issue equity in the future in connection with capital formation, acquisitions, strategic transactions or for other purposes. Based on the need for additional capital to fund expected growth, it is likely that we will issue additional securities to provide such capital and that such additional issuances may involve a significant number of shares of our common stock. Issuance of additional securities in the future will dilute the percentage interest of existing shareholders and may reduce the market price of our common stock and any other outstanding securities. Furthermore, the sale of a significant amount of our common stock by any selling security holders, including Mr. McEwen, may depress the price of our common stock. As a result, you may lose all or a portion of your investment.

General Risks

The Coronavirus pandemic could result in adverse operating results due to workforce reductions, supply and/or demand interruptions and travel restrictions.

On March 11, 2020, the World Health Organization (“WHO”) declared the COVID-19 virus a global pandemic. During late March and early April, our operations were disrupted by temporary shutdowns to protect our workforce from the spread of the virus. During the shutdown periods, rigorous policies and procedures were implemented at each site to minimize potential health and safety risks to our workforce. Though we have resumed operations at all our mine sites, the disruption in operations continue to adversely impact cash flows and liquidity and are expected to continue to have adverse consequences to us beyond 2020. Due to slowed ramp up in production and sales, our liquidity and financial condition have been adversely affected and we are at an increased risk of not having sufficient cash flow to fund our operations as well as an increased risk of default under our debt agreement. Achieving and maintaining normal operating capacity is also dependent on the continued availability and logistical delivery of supplies, which remains out of our control. The long-term impact of the COVID-19 outbreak on our results of operations, financial position and cash flows will depend on future developments, including the duration and spread of the outbreak and related advisories and restrictions and the viability and success of the worldwide vaccination roll out. Management continues to actively monitor the global situation on our financial condition, liquidity, operations, suppliers, industry and workforce.

We do not insure against all risks to which we may be subject in our operations.

While we currently maintain insurance policies to insure against general commercial liability claims and physical assets at our properties in the United States, Canada, Mexico and Argentina, we do not maintain insurance to cover all of the potential risks associated with our operations. We may also be unable to obtain insurance to cover other risks at economically feasible premiums or at all. Insurance coverage may not continue to be available, or may not be adequate to cover liabilities. We might also become subject to liability for environmental, pollution or other hazards associated with mineral exploration and production including bankruptcy of our refiners or other third party contractors which may not be insured against, which may exceed the limits of our insurance coverage or which we may elect not to insure against because of premium costs or other reasons. Losses from these events may cause us to incur significant costs that could materially adversely affect our financial condition and our ability to fund activities on our property. A significant loss could force us to reduce, temporarily suspend or, in the worst case, terminate our operations.

Our business is subject to the U.S. Foreign Corrupt Practices Act and similar worldwide anti-bribery laws, a breach or violation of which could lead to civil and criminal fines and penalties, loss of licenses or permits and reputational harm.

We operate in certain jurisdictions that have experienced governmental and private sector corruption to some degree. The U.S. Foreign Corrupt Practices Act and anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments for the purpose of obtaining or retaining business or other commercial advantage. Violations of these laws, or allegations of such violations, could lead to civil and criminal fines and penalties, litigation, and loss of operating licenses or permits, and may damage our reputation, which could have a material adverse effect on our business, financial position and results of operations. There can be no assurance that our internal control policies and procedures always will protect us from recklessness, fraudulent behavior, dishonesty or other inappropriate acts committed by our affiliates, employees or agents. As such, our corporate policies and processes may not prevent all potential breaches of law or other governance practices.

We depend on certain key personnel, and our success will depend on our continued ability to retain and attract such qualified personnel.

Our success is dependent on the efforts, abilities and continued service of certain senior officers and key employees and consultants. A number of our key senior officers, employees and consultants have significant experience in the precious metals industry. A loss of service from any one of these individuals may adversely affect our operations, and we may have difficulty or may not be able to locate and hire a suitable replacement.

We conduct operations in a number of foreign countries and are exposed to legal, political and social risks associated with those operations.

A significant portion of our revenue in 2020 was generated by operations outside the United States. Exploration, development, production and closure activities in many countries are potentially subject to heightened political and social risks that are beyond our control and could result in increased costs, capacity constraints and potential disruptions to our business. These risks include the possible unilateral cancellation or forced renegotiation of contracts in which we may, directly or indirectly, have an interest, unfavorable changes in foreign laws and regulations, royalty and tax increases (including taxes associated with the import or export of goods), risks associated with consumption taxes in Mexico, Argentina, and Canada, income tax refund recovery and collection processes in Mexico and Argentina, changes in US legislation as applicable to foreign operations, claims by governmental entities or indigenous communities, expropriation or nationalization of property and other risks arising out of foreign sovereignty over areas in which our operations are conducted. The right to import and export gold and silver may depend on obtaining certain licenses and quotas, which could be delayed or denied at the discretion of the relevant regulatory authorities, or could become subject to new taxes or duties imposed by U.S. or foreign jurisdictions, which could have a material adverse effect on our business, financial condition, or future prospects. In addition, our rights under local law may be less secure in countries where the rule of law is less robust and judicial systems may be susceptible to manipulation or influence from government agencies, non-governmental organizations or civic groups.

Any of these developments could require us to curtail or terminate operations at our mines, incur significant costs to renegotiate contracts, meet newly-imposed environmental or other standards, pay greater royalties or higher prices for labor or services and recognize higher taxes, or experience significant delays or obstacles in the recovery of consumption taxes or income tax refunds owed, which could materially and adversely affect our financial condition, results of operations and cash flows.

Our ongoing and future success depends on developing and maintaining productive relationships with the communities, including indigenous peoples, and other stakeholders in our operating locations. Notwithstanding our ongoing efforts, local communities and stakeholders can become dissatisfied with our activities or the level of benefits provided, which may result in civil unrest, protests, direct action or campaigns against us. Any such occurrences could materially and adversely affect our financial condition, results of operations and cash flows.

Our business could be negatively impacted by security threats, including cybersecurity threats, and other disruptions.

We face various security threats, including attempts by third parties to gain unauthorized access to sensitive information or to render data or systems unusable; threats to the safety of our employees; threats to the security of our infrastructure; and threats from terrorist acts. There can be no assurance that the procedures and controls we use to monitor these threats and mitigate our exposure to them will be sufficient in preventing them from materializing. If any of these events were to materialize, they could lead to losses of sensitive information, critical infrastructure, personnel or capabilities essential to

our operations and could have a material adverse effect on our reputation, financial condition, results of operations, or cash flows.

Our technologies, systems and networks, and those of our business partners, may become the target of cyber-attacks or information security breaches that could result in the unauthorized release, gathering, monitoring, misuse, loss or destruction of proprietary and other information, theft of property or other disruption of our business operations. In addition, certain cyber incidents, such as surveillance, may remain undetected for an extended period. A cyber incident involving our information systems and related infrastructure, or that of our business partners, could disrupt our business plans and negatively impact our operations. Although to date we have not experienced any significant cyber-attacks, there can be no assurance that we will not be the target of such attacks in the future. As cyber threats continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate any security vulnerabilities.

Several of our directors and officers are residents outside of the United States, and it may be difficult for shareholders to enforce within the United States any judgments obtained against such directors or officers.

Several of our directors and officers are nationals and/or residents of countries other than the United States, and all or a substantial portion of such persons’ assets are located outside of the United States. As a result, it may be difficult for investors to effect service of process on such directors and officers, or enforce within the United States any judgments obtained against such directors and officers, including judgments predicated upon the civil liability provisions of the securities laws of the United States or any state thereof. Consequently, shareholders may be effectively prevented from pursuing remedies against such directors and officers under United States federal securities laws. In addition, shareholders may not be able to commence an action in a Canadian court predicated upon the civil liability provisions under United States federal securities laws. The foregoing risks also apply to those experts identified in this report that are not residents of the United States.

The laws of the State of Colorado, our Articles of Incorporation and agreements with certain officers and directors may protect our directors from certain types of lawsuits.

The laws of the State of Colorado provide that our directors will not be liable to us or our shareholders for monetary damages for all but certain types of conduct as directors of the Company. Our Articles of Incorporation permit us to indemnify our directors and officers against all damages incurred in connection with our business to the fullest extent provided or allowed by law, including through stand-alone indemnity agreements. We have also entered into indemnification agreements with our executive officers and directors which require that we indemnify them against certain liabilities incurred by them in their capacity as such. The exculpation provisions may have the effect of preventing shareholders from recovering damages against our directors caused by their negligence, poor judgment or other circumstances. The indemnification provisions may require us to use our limited assets to defend our directors and officers against claims, including claims arising out of their negligence, poor judgment, or other circumstances.

Production Properties

Gold Bar mine, Nevada (100% owned)

For detailed information on the Gold Bar mine production statistics and financial results, refer to Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Overview and History

The Gold Bar mine is an open pit oxide gold mine with a processing facility, heap leach pad and gold recovery plant. The mine is located primarily on public lands managed by the BLM. We commenced project construction in November 2017 following receipt of the signed Record of Decision from the U.S. Environmental Protection Agency. The Gold Bar mine achieved commercial production on May 23, 2019.

​

The property is located within the Battle Mountain-Eureka-Cortez gold trend in Eureka County, Nevada. The property was previously mined from 1987 to 1994 by Atlas Precious Metals Inc.

Location and Access

The Gold Bar mine is located in the Southern Roberts Creek Mountains, in Eureka County, Nevada, approximately 30 miles northwest of the town of Eureka, Nevada, primarily in Township 22 North, Range 50 East (N39°48’16.5”; W116°21’09.65”). The mine site is accessed from US Highway 50 by travelling north on Robert’s Creek Road, an unimproved dirt road maintained by the Company. The mine area is approximately 15 miles from U.S. Highway 50.

Geology and Mineralization

The mine is located in the Battle Mountain-Eureka mineral belt in a large window of lower-plate carbonate rocks surrounded by upper-plate rocks. The lower-plate carbonates consist of an east-dipping section of Silurian Lone Mountain Dolomite, Devonian McColley Canyon Formation, Devonian Denay Formation, and Devonian Devils Gate Limestone (from oldest to youngest). Gold mineralization is hosted primarily in the Bartine Member of the McColley Canyon Formation, which consists of carbonate wackestones and packstones which are approximately 250 to 380 feet thick. Minor amounts of mineralization are found in the underlying dolomitic limestone Kobeh Member of the McColley Canyon Formation where it is adjacent to apparent feeder structures. The area where the project is located has “Carlin-Type” sediment-hosted gold mineralization characteristics with typical associated alteration (decalcification, silicification).

At Gold Ridge, extensive alteration (silicification) and gold mineralization occurs at surface and at depth proximal to three historical open pits. Drilling is ongoing to extend mineralization beyond the currently defined resource.

Facilities and Infrastructure

Gold Bar mine construction began in November 2017 with key site facilities and infrastructure completed by the end of 2018 and commercial production declared in May 23, 2019. The Gold Bar mine has well developed infrastructure including on-site power generation and transmission lines, water, natural gas and related supply utilities as well as buildings which support the operations and administration. The water supply for the Gold Bar mine and processing facilities comes from production wells located approximately two miles southeast from the site and powered by a diesel generator. The mining of the open pits is being carried out by a contractor and the mining progressed during 2020. Ore from the mine is transported to the crusher and conveyor system with the crushed and agglomerated material transported to the heap leach pad via an overland conveyor.

The ore is stacked onto the heap using a radial stacker and then leached with a weak cyanide solution to extract the precious metal values. The gold is then recovered from the pregnant solution in the carbon plant by adsorbing the dissolved gold onto activated carbon followed by desorption, electrowinning, retorting and smelting to recover the gold as a final doré product.

Exploration Activities

Exploration activities in 2020 focused on targets around the Gold Bar mine including drilling at the Gold Bar South target to support resource estimation and potential conversion to reserves and drilling at Ridge to test certain near-surface and deep targets. Gold Bar South, acquired by McEwen Mining in 2016, consists of 186 mining claims located approximately

24

Table of Contents

3.5 miles southeast from our Gold Bar mine. Gold Bar South hosts a near surface oxide gold deposit which, based on several historic higher-grade drill intersections, shows exploration potential laterally and at depth. See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations for more details. We expect to continue similar drilling at the Gold Bar property in 2021 with multiple near-surface targets identified.

Exploration Properties

Tonkin property (100% owned)

The Tonkin property represents our second largest holding within the Battle Mountain-Eureka Trend in Eureka County, Nevada with approximately 45 sq. miles of claims. The Tonkin property consists of the Tonkin deposit and the previously operating Tonkin mine.

From 1985 through 1989, the Tonkin mine produced approximately 30,000 ounces of gold utilizing an oxide heap leach and a separate ball mill involving bio-oxidation to treat refractory sulphide mineralized material. Due to cost escalation and recovery issues, the operation was shut down. The mine site is currently on care-and-maintenance and we continue to advance the reclamation program. We also continue evaluation work with respect to the Tonkin deposit.

Other exploration properties

We hold other exploration stage properties throughout Nevada which are not considered material at this time.

Production Properties

Black Fox mine and Stock mill, Canada (100% owned)

For detailed information on the Black Fox mine and Stock mill production statistics and financial results, refer to Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Overview and History

We acquired the Fox Complex in October 2017. It is located in the well-established Timmins Gold Mining district in Northern Ontario, Canada. Its main properties, Stock and Black Fox, are positioned along the Provincial Highway 101, with the Stock property 22 miles east of the city of Timmins and the Black Fox property 6 miles east of the town of Matheson. Given the proximity to communities in a region with primary industries of mining and forestry, local supplies and services are easily available and can be delivered in a timely manner to our operations.

​

The Black Fox mine refers to the current mining operation and is an underground gold mine and a key component of the complex, which also includes the Froome and Grey Fox deposits. The Black Fox mine initially produced from 1997 to 2001, operated by Exall Resources Limited. Re-commissioned by Brigus Gold Corporation, the mine restarted in early 2009. Primero Mining Corp. (“Primero”) acquired Brigus on March 5, 2014 and continued to operate the mine. We acquired the property on October 3, 2017 and continued the commercial operations.

​

Also, part of the Fox Complex, the Stock property hosts the Stock mill and is the site of the former Stock mine. Exploration initiated by us in 2018 and continuing in 2020 has defined two new mineralized zones at Stock East and Stock West, within a 2-mile mineralized trend along the Destor-Porcupine Fault.

​

The Black Fox mine contains 32 mining right parcels and 52 unpatented claims totaling 10 sq. miles of mining land. The complex also includes 6 sq. miles of surface land. All land parcels are located within Beatty and Hislop townships in the municipality of Black-River Matheson.

​

Location and Access

​

The Black Fox mine is located 6 miles east of Matheson, Ontario, and accessed directly from Highway 101 East. Matheson, in turn, is located approximately 45 miles from Timmins, which has a commercial airport. Timmins is approximately 342 miles by air north of Toronto.

​

The Stock mill is located approximately 17 miles from the Black Fox mine. Mineralized material is shipped to the mill from the Black Fox mine by truck.

​

Geology and Mineralization

​

All of our properties in the Timmins-Matheson region are located within the Archean aged, Abitibi greenstone belt. Gold mineralization at the Black Fox mine occurs in several different, geological environments within a complex system of structurally-prepared pathways (conduits) that host economic quantities of gold mineralization as: (1) free gold grains associated with shallow dipping quartz veins (aka ‘flats’) and stockworks within green carbonate and ankerite-altered

27

Table of Contents

ultramafic rocks; (2) gold associated with the development and distribution of pyrite, and (3) free gold carried within steeply dipping sigmoidal/sheared quartz veins.

​

Facilities and Infrastructure

​

The Black Fox mine property has well developed infrastructure including electricity, roads, water supply and high-speed internet access. There are seven fully serviced modular buildings which support various functions of the underground mine. There is also a maintenance shop, warehouse, compressed air plant, backfill plant and water management facilities. Mineralized material from the Black Fox mine is transported to, and processed at, the Stock mill, which has a nominal processing capacity of 2,000 tpd.

​

The primary water supply for the Black Fox mine comes from an on-site fresh water well and water produced from dewatering activities. Current water supplies are adequate to sustain current and planned future operations.

​

The Stock property, the site of our Stock mill, has well developed infrastructure including electricity, roads, water supply and high-speed internet access. There are also two buildings that support security and administration of the mill. There is an assay lab and several other buildings to support operations and milling, including a hoist house, warehouse and maintenance shop, mine dry building, crusher and conveyor systems and the mill building itself. The site also houses various support structures including storage and generator buildings.

​

Underground Mine Development

​

Froome, Canada (100% Owned)

​

The Froome deposit, which is part of the overall Fox Complex, is accessed from two declines from the bottom of the Black Fox pit and situated approximately one-half mile west of the Black Fox mine. The mineralized material from Froome will be hauled approximately 20 miles to the Stock Mine mill, where it will be processed. Life of mine production from the Froome deposit is expected to be approximately 2.5 years and low cost, bulk mining is expected to bridge gold production and provide cash flow while we continue to drill and assess potential additional resources at the Black Fox, Grey Fox, Stock and Lexam projects for future development towards expanded production.

​

Development of the underground access to the Froome deposit is on track, having advanced 76% by the end of the year. We plan to reach the main deposit in Q2 2021 and expect to achieve commercial production from Froome in Q4 2021. Froome offers several benefits compared to Black Fox such as a straighter, more efficient haulage route and wider, more consistent mineralization that is amenable to lower cost bulk mining methods. We are targeting an average annualized production rate of 40-45,000 gold equivalent ounces (“GEO”) from Froome over a period of approximately 2.5 years.

​

Advanced-Stage Properties

​

Grey Fox, Canada (100% owned)

​

The Grey Fox project is located 2.2 miles southeast of Black Fox mine, and is adjacent to Kirkland Lake Gold’s former

Hislop mine. Access is either by paved or well maintained, two-way, dirt roads.

​

An internal feasibility-level study was completed on the Grey Fox project in early 2015 by Primero, which recommended further development of the deposit. Further advanced project work continued until 2016, when Primero ceased all non-essential expenditures.

​

In 2019, we completed a substantial surface exploration program which focused on diamond drilling to increase and further define Grey Fox mineralized material. Exploration activities in 2020 further explored and defined the high-grade mineralization discovered at the Whiskey Jack target.

​

Exploration Properties

​

The Stock property is the site of the former Stock mine, which produced 137,000 ounces of gold from an underground operation between 1989 and 2005.

​

28

Table of Contents

Exploration activities (chiefly diamond drilling and geophysical surveys) were initiated at the Stock property in early 2018, and continued at a steady pace throughout 2019. These efforts led to growth of mineralized material at Stock East, and the discovery of a new source of potentially economic bulk mineralization known as Stock West sitting approximately 0.5 miles west of the existing mine workings. The Company resumed exploration at Stock West in late August 2020.

​

Other exploration properties acquired in connection with our acquisition of Lexam VG Gold Inc. in 2017 include Davidson-Tisdale, Fuller, Paymaster, and Buffalo Ankerite. We performed minimal work at these properties in 2020.

Overview and History

We own 100% of the El Gallo Project. The El Gallo Project was the open-pit gold mine and heap leach operation originally known as the Magistral mine. We operated the mine from September 2012 to June 2018, when we ceased active mining. Present activities are limited to residual leaching production that is expected to continue until the end of 2021, as well as closure and reclamation activities.

30

Table of Contents

The El Gallo Project consists of 8 sq. miles of concessions. Concession titles are granted under Mexican mining law. Mining concessions are subject to annual work requirements and payment of annual surface taxes which are assessed and levied on a semi-annual basis in accordance with Mexican law. An annual lease agreement for surface access to the El Gallo Project is currently in place.

Location and Access

The El Gallo Project and the surrounding properties are in northwestern Mexico in the western foothills of the Sierra Madre Occidental mountain range, within the State of Sinaloa in the Mocorito Municipality, approximately 60 miles by air northwest of Culiacan, the Sinaloa State capital city. The concessions are located approximately 2.5 miles by road from the town of Mocorito. Access is by paved and well maintained, two-way dirt roads.

Facilities and Infrastructure

The El Gallo Project property has well-developed infrastructure including electricity, roads, water supply and high-speed internet access. There is a truck shop, a warehouse, a fuel depot, core logging facilities, an explosives magazine, heap leach pads, process ponds, an assay laboratory, a three stage crushing plant, an ADR process plant with a sulfidation-acidification recovery (“SAR”) circuit added in the first quarter of 2018 and an administrative office. The laboratory is equipped to process all assay samples from the mine, core, chips and soil. The metallurgical lab is capable of determining cyanide leaching amenability and gold and silver recoveries of mineralized material amenable to cyanide leaching.

Advanced-Stage Properties

Fenix Project, Mexico (100% owned)

Overview and History

Two areas of mineralized material located inside of our property are currently considered for the Fenix Project and are the basis of the resource estimate included in the feasibility study released on February 16, 2021.

The Fenix Project contemplates a two-phase development process. Phase 1 includes the reprocessing of material on the gold heap leach pad at the existing El Gallo Project. Phase 2 includes the processing of open pit silver mineralization from El Gallo Silver at the existing process plant.

The process plant is expected to use conventional and proven mineral processing and precious metals recovery technologies. Phase 1 is envisioned to have a throughput rate of 5,000 tonnes per day. During Phase 2, mineralized material from the El Gallo Silver would be processed at a maximum of 3,250 tons per day.

Tailings produced during the operation would be stored in the mined-out Samaniego open pit at the El Gallo Project. As part of this process, tailings deposition would include a delivery system designed to maximize tailings consolidation and water recovery. Utilizing the in pit tailings storage technology is expected to be cost effective and environmentally friendly as it would reduce the disturbance footprint and construction material, eliminate the construction of a tailings dam, recycle process water, and reduce closure obligations by removing the leach pad.

During the second half of 2019, we received the environmental permit approval for in-pit tailings storage in the Samaniego pit and the additional approval for the process plant for Phase 1, which entails the construction of the Carbon-In-Leach (CIL) mill circuit. A decision to pursue the project remains under review.

Access and Location

The Fenix Project is located adjacent to the El Gallo Project and is similarly accessible.

Facilities and Infrastructure

The El Gallo Project infrastructure is used to support current work on the Fenix Project.

A change in power supply by self generation with natural gas is expected to be economical with reduced capital and operating expenditures compared to the previous National Grid option, using natural gas from Waha, Texas.

Los Azules Copper Project, Argentina (100% owned)

Overview and History

The Los Azules copper project is an advanced-stage porphyry copper exploration project located in the cordilleran region in the province of San Juan, Argentina near the border with Chile. In 1994, Minera Andes acquired lands in the southern portion of the Los Azules area. Over the years there was additional exploration done by Minera Andes and other companies who owned adjacent properties around Los Azules. We acquired Minera Andes in January 2012.

32

Table of Contents

During 2020, we continued preliminary engineering and cost estimates to advance the proposed low altitude all year access route (northern access route) in an effort to improve access to the site. We also advanced the Los Azules water management plan to evaluate the project operating as a zero discharge development.

The environmental baseline monitoring work continued as well as other works, which were identified as necessary to develop a conforming Environmental Impact Assessment (“EIA”) submission. The environmental work included the geological mapping of the tailings dam design.

Location and Access

The project is located at approximately 31o 13’30” South latitude and 70o 13’50” West longitude and abuts the Chile-Argentina border. It is accessible by unimproved dirt roads with seasonal closures in winter. The elevation at the site ranges between 11,500 feet to 14,750 feet above sea level.

Geology and Mineralization

The deposit is located within a copper porphyry belt that is host to some of the world’s largest copper mines. The upper part of the system consists of a barren leached cap, which is underlain by a high-grade secondary enrichment blanket. Primary mineralization below the secondary enrichment zone has been intersected in drilling up to a depth of more than 3,280 feet below surface.

Exploration Activities

Drilling conditions in the area are difficult, especially due to the presence of highly faulted zones and areas of loose surface scree or talus. Due to snow conditions on two mountain passes on the access road to the site, seasonal exploration typically commences in December and extends into late April. Drilling programs have been undertaken at Los Azules between 1998 and 2014 and in 2017 by four different mineral exploration companies: Battle Mountain Gold (now Newmont Corporation), Mount Isa Mines S.A. (now Glencore Plc.), Minera Andes and McEwen Mining. Drilling, including early reverse circulation programs, focused initially on gold exploration and subsequently on diamond drilling for porphyry style copper mineralization. Since 2013, we have focused on baseline studies regarding flora, fauna, water quality and other environmental compliance matters.

Facilities and Infrastructure

There are currently limited facilities or infrastructure located at the project site which mainly includes portable camp structures and drill platforms.

Production Properties

San José mine, Argentina (49% owned)

For detailed information on the San José mine production statistics and financial results, refer to Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Overview and History

The San José mine is an underground gold and silver mining operation located in Santa Cruz, Argentina. We acquired our interest in the San José mine in connection with our acquisition of Minera Andes in January 2012. The property is owned and operated under an option and joint venture agreement (“OJVA”) between Minera Andes (49%) and Hochschild (51%) in the name of MSC. The property was acquired by Minera Andes in 1997, followed by an extensive exploration program from 1997 to 2001, leading to the discovery of the Huevos Verdes and Saavedra West Zones. A feasibility study was completed in October 2005 under the direction of MSC and, following construction, commercial production was declared on January 1, 2008.

The mine is part of a larger property which covers a total area of approximately 1,004 sq. miles and consists of 141 mining concessions.

MSC has purchased the land and corresponding occupation rights that are necessary to conduct its operations.

Infrastructure at the property consists of camp facilities that can accommodate up to approximately 1,100 personnel, a medical clinic, a security building, a maintenance shop, a laboratory, processing facilities, a mine and process facility warehouse, a surface tailings impoundment, support buildings and mine portals, a change house, a core warehouse, an administration building and offices. The laboratory is equipped to process all assays (core, chips and soil). MSC has installed a satellite based telephone/data/internet communication system.

Electricity is provided by an 81 mile 132 kV electric transmission line, which connects the San José mine processing facility to the national power grid.

The San José mine is a ramp access underground mining operation.

Exploration Activities‌

During 2020, continued exploration focused on San José proximity targets, continued evaluating Aguas Vivas as planned and drill program started in Telken Norte.

​

In 2021, we expect the exploration programs to be focused on resources replacement with emphasis on extensions and new structures near to current operations as well as recognizance of new exploration targets over the district.

ITEM 3. LEGAL PROCEEDING S

We are not currently subject to any material legal proceedings. To the best of our knowledge, no such proceeding is threatened, the results of which would have a material impact on our properties, results of operations, or financial condition. Nor, to the best of our knowledge, are any of our officers or directors involved in any legal proceedings in which we are an adverse party.

ITEM 4. MINE SAFETY DISCLOSURES

At McEwen Mining, safety is a core value, and we strive for superior performance. Our health and safety management system, which includes detailed standards and procedures for safe production, addresses topics such as employee training, risk management, workplace inspection, emergency response, accident investigation and program auditing. In addition to strong leadership and involvement from all levels of the organization, these programs and procedures form the cornerstone of safety at McEwen Mining, ensuring that employees are provided a safe and healthy environment and are intended to reduce workplace accidents, incidents and losses, comply with all mining-related regulations and provide support for both regulators and the industry to improve mine safety.

The operation of our Gold Bar mine is subject to regulation by the Federal Mine Safety and Health Administration (“MSHA”) under the Federal Mine Safety and Health Act of 1977 (the “Mine Act”). MSHA inspects our Gold Bar mine on a regular basis and may issue citations and orders when it believes a violation has occurred under the Mine Act. While we contract a majority of the mining operations at Gold Bar to an independent contractor, we may be considered an “operator” for purposes of the Mine Act and may be issued notices or citations if MSHA believes that we are responsible for violations.

We are required to report certain mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K, and that required information is included in Exhibit 95 filed with this report.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Introduction

In the following discussion, “McEwen Mining”, the “Company”, “we”, “our”, and “us” refers McEwen Mining Inc. and as the context requires, its consolidated subsidiaries.

This section of this Annual Report on Form 10-K generally discusses 2020 and 2019 items and year-to-year comparisons between 2020 and 2019 with a particular emphasis on 2020. For a discussion of our financial condition and results of operations for 2019 compared to 2018, please refer to Item 7 of Part II, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC on March 16, 2020.

The technical contents of this management’s discussion and analysis has been reviewed and approved by Peter Mah, P.Eng., Chief Operating Officer and Luke Willis, Director, Resource Modelling as Qualified Persons as defined by Canadian Securities Administrator National Instrument 43-101 “Standards of Disclosure for Mineral Projects”.

With regard to properties and projects that are not in production, we provide some details of our plan of operation. This section provides information up to the date of filing this report.

The discussion contains financial performance measures that are not prepared in accordance with United States Generally Accepted Accounting Principles (“US GAAP” or “GAAP”). Each of the following is a non-GAAP measure: cash gross profit, cash costs, cash cost per ounce, all-in sustaining costs, all-in sustaining cost per ounce, average realized price per ounce, and liquid assets. These non-GAAP measures are used by management in running the business and we believe they provide useful information that can be used by investors to evaluate our performance and our ability to generate cash flows. These measures do not have standardized definitions and should not be relied upon in isolation or as a substitute for measures prepared in accordance with GAAP. Cash Costs equals Production Costs Applicable to Sales and is used interchangeably throughout the document.

For a reconciliation of these non-GAAP measures to the amounts included in our Statements of Operations for the three months ended December 31, 2020 and 2019 and the years ended December 31, 2020, 2019 and 2018 and to our Balance Sheets as of December 31, 2020 and 2019 and certain limitations inherent in such measures, please see the discussion under “Non-GAAP Financial Performance Measures”, on page 58.

This discussion also includes references to “advanced-stage properties”, which are defined as properties for which advanced studies and reports have been completed indicating the presence of mineralized material or proven and probable reserves, or that have obtained or are in the process of obtaining the required permitting. Our designation of certain properties as “advanced-stage properties” should not suggest that we have or will have proven or probable reserves at those properties as defined by the SEC Industry Guide 7. This section provides information up to the date of the filing of this report.

The information in this section should be read in conjunction with our consolidated financial statements and the notes thereto included in this Annual Report on Form 10-K.

Throughout this Management’s Discussion and Analysis (“MDA”), the reporting periods for the three months ended March 31, 2020, June 30, 2020, September 30, 2020, December 31, 2020, and December 31, 2019 are abbreviated as Q1/20, Q2/20, Q3/20, Q4/20 and Q4/19, respectively, the reporting periods for the six months ended June 30, 2020 and December 31, 2020 are abbreviated as H1/20 and H2/20, respectively, and the reporting for the years ended December 31, 2020 and 2019 are abbreviated as YTD/20 and YTD/19 respectively.

In addition, in this report, gold equivalent ounces (“Au Eq. oz”) includes gold and silver ounces calculated based on a 94:1 ratio for the first quarter of 2020, 104:1 for the second quarter of 2020, 79:1 for the third quarter of 2020, and 77:1 for the fourth quarter of 2020. Beginning with the second quarter of 2019, we adopted a variable silver to gold ratio for reporting that approximates the average price during each fiscal quarter.

Note: We ceased active mining and processing at the El Gallo mine in the second quarter of 2018. Where comparative results for mining operations are presented for prior periods, we continue to use the term “El Gallo Mine.” We use the

term “El Gallo Project” to refer to the ongoing reclamation and residual heap-leaching that is taking place at the formerly-producing mine.

COVID-19 Pandemic

​

On March 11, 2020, the World Health Organization (“WHO”) declared the COVID-19 virus a global pandemic. During late March and early April, our operations were disrupted by temporary shutdowns to protect our workforce from the spread of the virus. A summary of our operations during 2020 is as follows:

​

| ● | All operations at Black Fox were temporarily suspended on March 26 and resumed on April 13;

| ● | Mining operations at the Gold Bar mine were suspended on April 1 and resumed on May 4, while leaching activities continued throughout the suspended period;

| ● | Operating activities at the El Gallo Project were suspended on April 1, while leaching activities continued. Operations resumed June 1;

| ● | Operations at the San José mine owned by MSC (operated by our joint venture partner) closed March 20 and resumed with scaled back operations by the end of April. In the third quarter, operations at the San José mine were again in a ramp-up phase as a result of the ongoing countrywide restrictions on the movement of people. On November 30, 2020 the government mandated a shutdown of mine operations in the region. Operations at the San José mine resumed on December 8, 2020; and

| ● | Our head office in Toronto, Canada was shut down on March 13 and remains closed. All employees are performing their functions remotely.

​

During and after the shutdown periods, rigorous policies and procedures have been implemented at each site to minimize potential health and safety risks to our workforce.

​

The temporary shutdowns have adversely impacted our mine operations, cash flow, and liquidity throughout 2020. In addition to the adverse effect on production and revenue, we have incurred costs in connection with the shutdowns and subsequent ramp-up at each operation. Our liquidity and financial condition have been adversely affected and as a result we have raised an additional $64.4 million in gross equity financings from September 2020 to February 2021. In addition, we renegotiated more favorable debt repayment terms in Q2 2020. We are currently maintaining normal operating capacity at our operations; however this remains dependent on the continued availability and logistical delivery of supplies, which remains out of our control. The long-term impact of the COVID-19 outbreak on our results of operations, financial position and cash flows will depend on future developments, including the duration and spread of the outbreak, related advisories and restrictions and the viability and success of the worldwide vaccination roll out. Management continues to actively monitor the global situation with respect to COVID-19 and its ongoing impacts on our financial condition, liquidity, operations, suppliers, industry and workforce.

​

The governments of the United States, Canada and Mexico have enacted or proposed legislation to provide relief to companies and/or individuals affected by the enforced reduction in operations. During 2020, we secured $1.9 million of relief from the US government under the paycheck protection (“PPP”) program. The funds are fully forgivable so long as sufficient eligible expenditures were incurred in a 24 week period. The income from the PPP program is recognized on a systematic basis as eligible forgivable expenditures are incurred. As at December 31, 2020, the full amount has been recognized as other income, as the Company is reasonably assured that it is in compliance with the forgiveness criteria of incurring the eligible expenses for forgiveness within the required timeframe. We also secured $4.5 million of government relief in Canada through the Canadian Emergency Wage Subsidy (“CEWS”) program.

2020 AND Q4/20 OPERATING AND FINANCIAL HIGHLIGHTS

Highlights for the year and quarter ended December 31, 2020 are summarized below and discussed further in the Consolidated Financial Performance:

​

COVID-19 Impacts

​

| ● | Operations were temporarily suspended in Q2/20 in efforts to prevent the spread of COVID-19 among our workers, business partners, and communities. Production successfully resumed at our operating mines during Q3/20 and they remain in operation as at December 31, 2020.

| ● | The San José mine continued to operate below normal capacity during Q3/20 and Q4/20 due to government imposed travel restrictions. On November 30, 2020, the government mandated a temporary shutdown of mine operations in the region. Operations at the San José mine resumed on December 8, 2020.

​

Performance

​

| ● | We produced 114,844 gold equivalent ounces in 2020; production includes 54,500 gold equivalent ounces from the San José mine(1). We produced 30,227 gold equivalent ounces in Q4/20, including 14,805 attributable gold equivalent ounces from the San José mine(1).

| ● | We sold 115,662 gold equivalent ounces in 2020, including 54,929 attributable gold equivalent ounces from the San José mine (1). We sold 30,228 gold equivalent ounces in Q4/20, with 15,071 attributable ounces from the San José mine (1).

​

Cash Flow and Results of Operations

​

| ● | We reported cash and cash equivalents of $20.8 million at December 31, 2020; we raised $20.2 million (net proceeds of $19.6 million) through two flow-through financings in 2020.

| ● | Subsequent to the year end, we raised additional gross proceeds of $12.7 million and $31.5 million through a Canadian development expenditures (“CDE”) flow-through and an equity financing.

| ● | We re-negotiated the debt facility to remove immediate liquidity issues in 2020.

| ● | We reported 2020 revenue of $104.8 million from the sale of 60,733 gold equivalent ounces from our 100% owned properties; at an average realized price(2) of $1,771 per gold equivalent ounce.

| ● | We reported cash gross loss(2) of $4.0 million in 2020, with a gross loss of $26.9 million.

| ● | We reported 2020 net loss of $152.3 million, including an $83.8 million impairment adjustment for the Gold Bar Mine and $27.5 million spent on exploration and advanced projects. The 2020 net loss was $68.5 million before the impairment adjustment for the Gold Bar mine.

​

Exploration and Reserves

​

| ● | We completed two flow-through financings in Q3 and Q4, which provided gross proceeds of $10.4 million and $9.8 million, respectively (combined net proceeds of $19.6 million). These proceeds will be used to incur eligible exploration expenditures in the Timmins region over the next one to two years with the primary focus around the Stock West, Grey Fox and Whiskey Jack targets.

​

CONSOLIDATED PERFORMANCE

​

For the year ended December 31, 2020, we reported a net loss of $152.3 million (or $0.38 per share) compared to a net loss of $59.7 million in 2019 (or $0.17 per share). The increased loss from year to year relates primarily to a non-cash impairment charge of $83.8 million in 2020 at Gold Bar; lower revenues of $12.2 million predominantly as a result of lower production from all sites in 2020 versus 2019; and higher cost of sales of $25.5 million in 2020 as a result of COVID-19 related production suspensions and related costs; and higher production costs from Gold Bar operations in 2020. These changes were partially offset by a reduced loss from our investment in MSC, and reduced general and administration as well as exploration costs in 2020 versus 2019. MSC’s results benefited from significantly higher average realized gold and silver prices (27% and 41% higher average gold and silver prices) and lower depreciation and depletion expenses due to lower mineralized material mined and processed.

​

Cash gross loss (a non-GAAP measure) of $4.0 million for 2020 decreased by $37.7 million compared to a cash gross profit of $33.7 million in 2019, mainly as the result of the decrease in production and revenue, coupled with higher production costs applicable to sales due to higher costs per ounce in particular at Gold Bar due to operational and grade

reconciliation issues. This has been ongoing and drilling continued throughout 2020 and is ongoing to date, as well as updated independent technical studies, to mitigate this risk. See “Non-GAAP Financial Performance Measures” for a reconciliation to gross (loss) profit, the nearest GAAP measure.

​

Production from our 100% owned mines of 60,343 gold equivalent ounces in 2020 decreased by 22,423 gold equivalent ounces compared to 2019. The decrease is attributed to the temporary shutdowns of our mine operations in efforts to combat the spread of COVID-19 during the first half of 2020. Operations resumed, however, below capacity throughout most of 2020, given the challenges in mobilizing personnel and with government imposed travel restrictions. In addition to the impacts of COVID-19 on our operations in 2020, production at the El Gallo Project decreased by 8,261 gold equivalent ounces compared to 2019, as leaching continued to wind down.

​

Our share of the San José mine production of 54,500 gold equivalent ounces in 2020 was 37,153 ounces lower than in 2019; this decrease is attributable to the slow ramp up back to full production due to government imposed travel restrictions to combat the spread of COVID-19 for most of 2020.

​

CONSOLIDATED FINANCIAL REVIEW

​

Year ended December 31, 2020 compared to 2019

​

Revenue from gold and silver sales in 2020 of $104.8 million decreased by 10% compared to 2019. The decrease reflects 24,402 fewer gold equivalent ounces sold from our 100% owned mines in 2020 compared to 2019, partially offset by a higher average realized price ($1,771/oz or $368/oz higher compared to 2019).

​

The decrease in gold equivalent ounces sold includes 8,763 fewer gold equivalent ounces sold from the El Gallo Project as the operations continue to wind down, 12,923 fewer gold equivalent ounces sold from the Black Fox mine and 2,716 fewer gold equivalent ounces sold from the Gold Bar mine as a result of operational interruptions. The ongoing reserve estimate work culminated in an updated technical report filed on February 22, 2021. All of our operations were impacted by COVID-19 throughout 2020.

​

Production Costs applicable to sales in 2020 increased by 31% to $108.8 million compared to 2019; gold equivalent ounces sold in 2020 were 29% fewer than in 2019 but at a higher cash cost per ounce sold as explained in the “Consolidated Performance” section above.

​

Depreciation and depletion in 2020 decreased by $1.9 million to $22.9 compared to 2019, reflecting the decrease in gold equivalent ounces sold in 2020 and the lower depreciable and depletable asset base as a result of the impairment charge recorded at Gold Bar in the first quarter of 2020.

​

Advanced projects of $11.7 million for 2020 increased by $2.2 million compared to 2019. Advanced projects in 2020 included continued spending for the Froome development project in Timmins Ontario, engineering and permit work at the Gold Bar South property in Nevada and the Fenix project in Mexico.

​

Exploration costs of $15.9 million for 2020 decreased by $21.8 million compared to 2019. In 2020, exploration activities ramped up in the second half of the year as we announced the closing of two flow-through financing programs. Through December 31, 2020, we have incurred $1.9 million in qualifying exploration expenditures. Expenditures relate to exploration activities in Timmins at the Stock and Grey Fox targets. Exploration costs in 2019 related to expenses incurred at the Company’s Timmins operations.

​

General and administrative expenses of $9.2 million for 2020 decreased by $3.6 million, compared to 2019, due to lower salaries, financing fees, and a reduction in corporate activities in marketing and travelling in 2020 due to COVID-19.

​

Loss from investment in MSC of $1.5 million in 2020, decreased by $7.2 million from 2019, reflecting increased gross profits of $8.4 million.

​

Revision of estimates and accretion of asset retirement obligations of $1.8 million in 2020, decreased by $1.7 million from 2019, primarily due to the inclusion of the asset retirement obligations at the Gold Bar mine in 2019 as it transitioned to commercial production in May 2019. There was no such addition in 2020.

Impairment of property, plant and equipment at Gold Bar was $83.8 million. During the first quarter of 2020, we performed a comprehensive review of our Gold Bar mine and determined that indicators of impairment existed. A recoverability test was performed and we concluded that the carrying value of the long-lived assets for the Gold Bar mine was impaired based on a reduction in preliminary estimated resources and expected future production at that time. Technical work and drilling has continued throughout 2020 to better understand the resources, which culminated in an updated reserve and resource estimate announced on January 7, 2021, with an updated technical report filed on February 22, 2021. The following are key points noted in the updated technical report:

| 1. | The feasibility study base case using a gold price assumption of $1,500/oz estimates a life of mine discounted after-tax value of $55.2 million at an 8% discount rate.

| 2. | Over the expected 6-year mine life, production is expected to total 17.2 million tons of ore at a diluted gold grade of 0.025 oz/t (0.84 g/t) for a total payable gold of 302,000 oz as at December 1, 2020. This represents a net reduction of 16% in estimated reserves, relative to the reserve estimate as at December 31, 2018 of 430,000 gold ounces.

Other operating of $2.0 million compared to $nil in 2019 and reflects the expenses relating to the suspension of our operations at the Gold Bar and Black Fox mines primarily related to COVID-19 costs.

​

Other income was $6.9 million for 2020 compared to $7.1 million for 2019. Other income in 2020 includes proceeds received from COVID-19 relief funds. The 2019 amount relates primarily to gains on marketable securities of $5.3 million.

​

Income and mining tax recovery of $1.4 million for 2020 decreased by $2.4 million from 2019. The decease is mainly due to lower amortization of the flow-through premium in 2020 as compared to 2019. In addition, the income and mining tax recovery reflects the devaluation of the Argentine and Mexican peso against the U.S. dollar on the Company’s peso-denominated deferred tax liability and the reversal of deferred tax liabilities on the impairment of the US properties.

LIQUIDITY AND CAPITAL RESOURCES

Our cash and cash equivalents balance at December 31, 2020 of $20.8 million decreased by $25.7 million from the balance at December 31, 2019. The decrease in cash and cash equivalents at December 31, 2020 was due to $27.9 million of cash used in operations and $13.4 million invested in mineral property interests and plant and equipment, partly offset by $17.6 million in cash provided by financing activities. Cash provided from financing activities included gross proceeds of $20.2 million (net proceeds of $19.6 million) from the issuance of flow-through shares on September 10, 2020 and December 31, 2020. We are required to spend the flow-through proceeds on flow-through eligible Canadian exploration expenditures (“CEE”) as defined by subsection 66(15) of the Income Tax Act (Canada). We expect to fulfill our CEE commitments by the end of 2022. For more details on our flow-through financing refer to Note 14 to the Consolidated Financial Statements, Shareholders’ Equity.

​

Working capital at December 31, 2020 of $7.9 million decreased by $35.2 million from December 31, 2019, reflecting the decrease of $25.6 million in cash and cash equivalents and the decrease of $11.4 million in inventory, primarily in materials on the leach pads at the Gold Bar and El Gallo projects, which was partially offset by the decrease in current liabilities as result of the debt refinancing.

Cash used in operations of $27.9 million in 2020 decreased from $39.5 million cash used in operations in 2019. The change is attributed to a decrease in exploration expenses of $21.8 million, receipt of COVID-19 related relief funds of $6.4 million, a decrease in general and administrative expenses of $3.6 million and an increase in accounts payable of $2.0 million in 2020; partially offset by a decrease in revenue of $12.2 million and increased production costs of sales adjusted for inventory write-downs of $11.6 million.

Cash used in investing activities of $11.8 million in 2020 decreased from $14.1 million in 2019. The net difference of $2.3 million is primarily due to a decrease of $16.3 million in spending on mineral property interest and plant and equipment as the construction of the Gold Bar mine was completed in May 2019. This decrease was partially offset by lower proceeds from sale of investments ($1.3 million in 2020 compared to $6.8 million in 2019) and lower dividends received from MSC ($0.3 million in 2020 compared to $8.9 million in 2019). On January 28, 2021 we received a dividend of $2.5 million from MSC, refer to Note 23 – Subsequent Events, to the Consolidated Financial Statements.

During 2020, we spent $13.4 million on mineral property and plant and equipment, (a decrease of $16.3 million from the year 2019), predominantly on capital development, with the spending mainly related to underground development at the Fox Complex and infill drilling at Gold Bar.

Financing activities provided $17.6 million in cash in 2020 compared to $70.0 million in 2019. In 2020, this included $19.6 million from the issuance of flow-through shares, slightly offset by $2.2 million in lease obligations payments. The proceeds will be used to incur CEE at the Grey Fox, Stock and Whiskey Jack targets in Timmins over the next 2 years.

In June 2020, the loan facility was amended under a new administrative agent resulting in an extension of the required principal payments. The amendment also reduced the minimum working capital covenant to $nil at December 31, 2020. The remainder of the agreement remains in full force and effect.

During the year and subsequent to year end the Company closed on $64.4 million in gross proceeds from equity financings. As a result of this, the Company believes it has sufficient liquidity along with funds generated from ongoing operations, to fund anticipated cash requirements for operations, capital expenditures and working capital purposes. As a result, the previously disclosed going concern uncertainty disclosure has been removed, as substantial doubt no longer exists regarding the Company’s ability to meet its obligations as they become due within one year after the date that the financial statements are issued. Refer to Note 14 – Shareholders and Equity Note 23 – Subsequent Events, to the Consolidated Financial Statements.

​

Despite the significant impacts of the COVID-19 pandemic and outbreaks in the region, the Gold Bar mine produced 27,900 gold equivalent ounces in 2020 compared to 30,700 GEOs the year prior. The COVID-19 outbreak had a significant impact on production as the Gold Bar operation shut down for part of Q2 and isolation quarantine protocols resulted in reduced operating shifts in Q4 after positive COVID-19 tests of site personnel. The slower ramp up to full mining rates following the shut down was primarily due to delays related to mining contractor rehiring of operators after the shutdown resulting in slower than planned equipment operation, and the Company completing drilling, assaying, and an updated in-house resource model to develop a plan forward that includes mining from Gold Bar South. When compared to 2019 there were less ore tonnes mined, lower grades and a reduced gold production as a result. We continue to execute improvement initiatives at Gold Bar targeted to support the turnaround of the operations, which includes but are not limited to the following: improving contractor mining efficiencies, processing optimizations and ongoing exploration drilling targeting potentially economic near term gold production mineralization.

​

During Q4/20 and into Q1/21, a final updated resource model and updated resource and reserve estimates were completed which provided us with a more accurate model to plan from moving forward as compared to the 2018 feasibility study. A

feasibility study update for Gold Bar was filed on February 22, 2021. The following are key points noted in the updated technical report:

| 1. | The feasibility study base case using a gold price assumption of $1,500/oz estimates a life of mine discounted after-tax value of $55.2 million at an 8% discount rate.

| 3. | Over the expected 6-year mine life, production is expected to total 17.2 million tons of ore at a diluted gold grade of 0.025 oz/t (0.84 g/t) for a total payable gold of 302,000 oz as at December 1, 2020. This represents a net reduction of 16% in estimated reserves, relative to the reserve estimate as at December 31, 2018 of 430,000 gold ounces.

With respect to our operational experience at Gold Bar, the majority of material mined during 2020 was from the Pick West pit with the remainder of the Cabin reserve being mined and completed in Q1. The transition in 2020 to mining from the Pick West pit has returned lower ore tonnes, gold grade and contained ounces from the upper benches as compared to the feasibility block model. This is due to greater structural control of the mineralization than was previously expected, but which was exposed in the newly developed pit. Due to the differences observed between the modeled and mined ore tonnage and grade from the Pick West pit, the reserve estimate as at December 31, 2018 and the future mine plan were re-evaluated. Remodeling of these deposits have been completed in-house and reviewed by an independent third party engineering firm. Optimization of this reserve will continue into 2021 to improve ore deliveries to the pad.

​

Revenue from gold and silver sales increased by $5.1 million compared to 2019. The increase is attributed to the higher average realized gold prices in 2020 partially offset by lower gold equivalent ounces sold. The decrease in ounces sold is as a result of the COVID-19 restrictions and the underperformance of Pick West actual mining to plan as discussed above.

​

Production costs applicable to sales was $58.5 million for 2020 versus $33.6 million in 2019. The production cost variance from year to year is related mainly to the start of leach pad stacking in 2019 and as a result a significant portion of those costs were recognized on the balance sheet as build up of inventory, whereas, in 2020 there were higher costs related to the historically mined gold ounces being drawn down from the heap leach and in-circuit inventory balances and recognized in production costs.

​

Cash cost and AISC per gold equivalent ounce of $2,106 and $2,459 were negatively impacted by the lower ore tonnes mined and placed on the heap leach pad at a decreased grade, as noted above. They were also impacted by $4.5 million of pre-strip costs and $12.4 million in write-downs of the stockpile, heap leach and in-circuit inventory balances. Higher costs were partially offset by work force and contractor reductions.

​

Gold Bar mine impairment

​

In Q1/20, we recorded an impairment charge of $83.8 million based on the preliminary revised mine plan, which indicated a significant reduction in contained ounces relative to the 2018 reserve estimate. The impairment charge reduced the carrying value of the Gold Bar mineral property interests and plant and equipment.

​

Evaluation of the resource estimate continued through the fourth quarter of 2020 and an updated resource and reserve estimate and feasibility study update for Gold Bar Mine was filed on February 22, 2021, with economic highlights noted above.

​

Exploration Activities – Nevada

​

In 2020, we spent $5.1 million on exploration activities in and around the Gold Bar mine. This is compared to the $7.2 million spent on exploration activities in Nevada in 2019.

​

The exploration activities in 2020 included 110,500 feet (33,700 m) of drilling and metallurgical testing to support the updated Reserve estimates. The drilling program included 64,000 feet (19,500 m) at the Pick deposit, 35,000 feet (10,700 m) at Gold Bar South, and an ongoing drill program at the Gold Ridge deposit with 11,500 feet (3,500 m) drilled to date.

​

Drilling at Gold Bar South has successfully advanced the project and is expected to contribute to Gold Bar mine’s future production. Subject to the receipt of permit approvals as planned, the mining of Gold Bar South could begin as early as in Q1 2022.

Canada Segmen t

​

The Canada segment is comprised of the Fox Complex, which includes the Black Fox gold mine, the Froome underground mine development and the Grey Fox and Stock advanced-stage projects, the Stock mill, and other gold exploration properties located in Timmins, Ontario, Canada.

Black Fox mine and Froome mine development

The Black Fox mine plan currently shows production winding down in H1 2021 while exploration will continue following up on known target areas with the aim to extend potentially economic mineralization and mine life. There are 111,000 ounces in the life of mine plan at the Froome Project and with more surface and underground exploration drilling planned to extend the Froome deposit near existing and planned infrastructure. Underground development will continue to advance towards the deposit in 2021. We expect to reach the main deposit in early Q2 2021, and achieve commercial production in Q4 2021.

The following table sets out operating results for the Black Fox mine for the three months ended December 31, 2020 and 2019, and the years ended December 31, 2020, 2019, and 2018:

​

2020 compared to 2019

Production decreased by 11,300 gold equivalent ounces or 32% mainly due to lower gold grades processed in 2020. In addition, mined mineralized tonnes were negatively impacted by a suspension of mining activities due to COVID-19. In the second half of the year, grade reconciliation and performance improved following more drill accesses and tighter drill spacings, a greater number of mining headings available, improved sequencing and timing, improved resource modelling accuracy and improved grade control and mining practices.

Revenue from gold and silver sales decreased by $8.6 million or 17% in 2020 compared to 2019. The change reflects a 12,923 gold equivalent ounce decrease in sales due to the technical and operational issues discussed above, partially offset by an increase in average gold price realized.

Production costs applicable to sales increased by $3.5 million or 11% compared to 2019, despite fewer gold ounces produced and sold. The increase in production costs applicable to sales is due to underground development costs being expensed as incurred due to the end of mine life.

All-in sustaining costs decreased by $5.3 million or 11% to $40.9 million in 2020, compared to 2019, due to lower sustaining capital expenditures. All-in sustaining cost per gold equivalent ounce increased in 2020 to $1,650/oz versus $1,225/oz in 2019, primarily due to 34% less gold equivalent ounces sold in 2020.

Froome Underground Mine Development

​

The Froome deposit which is part of the overall Fox Complex, is accessed from two declines at the bottom of the Black Fox pit and situated approximately one-half mile west of the Black Fox mine. The mineralized material from Froome will be hauled approximately 20 miles to the Stock Mine mill, where it will be processed.

We expect that the Froome underground decline development will access the deposit in early Q2 2021 and as of December 31, 2020 has advanced 76% of the plan. Life of mine production from the Froome deposit is estimated to be approximately 2.5 years and low cost, bulk mining is expected to bridge gold production providing cashflow while we continue to drill and assess potential additional resources at the Black Fox, Grey Fox, Stock and Lexam projects for future development towards expanded production.

We expect that operational synergies through shared resources and infrastructure with the ongoing production of the Fox Complex will improve the production and cost profile for the combined projects.

​

Exploration Activities and Expansion Study – Timmins

We remain focused on our principal exploration goal of cost-effectively discovering and extending gold deposits adjacent to our existing operations to contribute to near-term gold production. We incurred $6.5 million in 2020 for exploration initiatives, compared to $25.8 million in 2019.

​

Black Fox mine

​

In the first half of 2020, underground drilling at the Black Fox Mine continued to return encouraging high-grade intercepts at depth before being transitioned to infill drilling for near term production opportunities. The exploration activities during 2020 were confined to 42,526 feet (12,962 meters) of underground diamond drilling and related sample analysis in order to discover and identify additional mineralization adjacent to the Black Fox ore body. There is a strong potential to extend the mineralization to greater depths as well as towards the western margin of the ore body, as the mineralization remains open in all directions.

​

Grey Fox project

​

Exploration drilling commenced within the northern portion of the Grey Fox mineralization in August 2020. One drill rig was primarily focused on advancing the Whiskey Jack discovery made in late 2019, coring 16,634 feet (5,070 meters) prior to its transfer to our Stock exploration site.

​

Highlights of the Whiskey Jack drilling campaign were presented in our October 16, 2020 news release.

​

Stock property

​

The Stock exploration area sits adjacent to our Stock mill, which currently processes ore from our Black Fox mine. This facility processed ore from the historical underground Stock mine, which operated intermittently from the early 1980s until 2004, generating a total of 137,000 ounces of gold.

​

The Stock West mineralized zone was discovered in mid-2019; in 2020 five drill rigs completed 53,642 feet (16,350 meters) of follow-up drilling. Initial results suggest the potential to define a significant new zone of mineralization 800m (1/2 mile) from our Stock processing facility.

​

We returned our efforts to this high-priority target in late August by adding four surface drill rigs. The majority of our Q4 drilling was designed to infill the gaps between our encouraging 2019 intercepts. This will increase the density of the data needed to develop a 3D model and to generate an initial resource estimate. Four contracted drill rigs completed a total of 58,593 feet (17,859 meters) by year-end. Drill crews returned to site in early January 2021 as we continue to advance the potential of the Stock property. Assuming this drilling is successful in identifying sufficient gold to support a decision to re-open the historic Stock Mine, we are well positioned to act quickly and begin dewatering the mine in the second half of 2021. Previously the mine was dewatered in just 4 months through the existing shaft workings.

Fox Complex Expansion – Economic Study

​

We have engaged an independent engineering group to complete a Preliminary Economic Assessment (PEA) on the Grey Fox - Black Fox, Stock and Timmins resources utilizing our existing central milling capacity. The PEA is expected to be completed in the second quarter of 2021. The objective of the PEA is to develop a plan for the Fox Complex over a 10-year life. Production growth is envisioned to start ramping up in 2022.

Cash costs and All-in-sustaining costs and Cash cost and AISC per gold equivalent ounce

​

As the El Gallo Project’s gold and silver production and sales are the result of residual leaching activities, we have ceased relying on, and disclosing, cash cost and all-in sustaining cost per gold equivalent ounce as key metrics for the Project. The economics of residual leaching are measured by incremental revenues exceeding incremental costs; residual leaching is expected to continue as long as incremental revenues exceed incremental costs. Cash costs and all-in sustaining costs include, in addition to current period residual leaching costs, prior-year leach pad inventory costs expensed in the current period, with the latter not relevant on the evaluation of the economics of the residual leaching operations. Residual leaching costs for the year ended December 31, 2020 were $11.4 million, or $1,409 per gold equivalent ounce.

​

El Gallo project recoveries

​

Due to long process cycles, actual recoveries from the heap are difficult to measure and may fluctuate significantly based on the timing, quantity and metallurgical attributes of the mineralized material placed on the leach pads, among other variables. The cumulative recovery rate realized for gold production from September 1, 2012 (start of production) to December 31, 2020 including residual heap leaching activities following the cessation of mining activities in the second quarter of 2018, is estimated at 65%.

​

The residual leaching activities in El Gallo are expected to continue in 2021 or until it remains economical.

​

2020 compared to 2019

​

Production and revenue continued to decrease in 2020 reflecting the prior cessation of active mining as the operation moved into residual heap leaching in mid-2018. The decrease in revenue was due to the decrease in production of 50% partially offset by a higher average realized gold price.

​

Costs increased in 2020 due to a $1.7 million write-down of the stockpile, heap leach and in-circuit inventory balances.

Advanced-Stage Properties – Fenix Project

McEwen Mining announced on December 31, 2020 the results of a feasibility study for the development of its 100%-owned Fenix Project, which includes the El Gallo Gold and El Gallo Silver deposits, located in Sinaloa, Mexico.

The study envisions a 9.5-year mine life with an attractive after-tax IRR of 28% using $1,500/oz gold and $17/oz silver, with an estimated initial capital expenditure of $42 million for Phase 1 and $24 million for Phase 2. The project implementation is envisioned in two distinct phases: Phase 1 (years 1 to 6) - gold production from heap leach reprocessing, and Phase 2 (years 7 to 10) - silver production from open pit mining.

The key environmental permits for Phase 1 were received in Q3 2019, including the approval for an in-pit tailings storage facility and process plant construction.

We incurred $2.5 million during 2020 on activities required to advance the Fenix Project. This compares to the $2.4 million we spent during 2019. The Fenix Project feasibility study was published on February 16, 2021.

The feasibility study is available for review on our website and SEDAR (www.sedar.com).

The Company is currently evaluating multiple financing alternatives, including the potential divestiture of our Mexican business unit.

​

The comparative analysis below compares the operating and financial results of MSC on a 100% basis.

​

2020 compared to 2019

​

Gold and silver production decreased by 38% and 40%, respectively, in 2020 compared to 2019 as a result of a 26% decrease in processed mineralized material, coupled with 17% and 19% decreases in the average grades of gold and silver, respectively, of the mineralized material processed in 2020. The decrease in processed mineralized material reflected the suspension of mining activities due to COVID-19 followed by operating below capacity, as the ongoing countrywide restrictions on the movement of people resulted in the ramp-up being phased over a significant period of time.

​

Revenue from gold and silver sales decreased by 17% in 2020 compared to 2019, reflecting fewer gold equivalent ounces sold due to lower production as noted above, partially offset by higher average realized gold and silver prices in 2020.

54

Table of Contents

​

Cash costs decreased by $21.7 million or 14% in 2020 compared to 2019, reflecting lower activity related to tonnes of mineralized material processed and fewer ounces produced and sold. All-in sustaining costs for 2020 decreased by $40.5 million or 19% compared to 2019, mainly due to lower cash costs, coupled with lower capitalized underground mine development and sustaining capital investment in plant and equipment.

​

Cash cost and all-in sustaining cost per gold equivalent ounce sold were higher for 2020 compared to 2019, as lower aggregate fixed cash costs and AISC were spread over 39% fewer gold equivalent ounces sold, as noted above.

​

Investment in MSC

​

Our 49% attributable share of operations from our investment in MSC was a loss of $1.5 million in 2020, compared to a loss of $8.8 million in 2019, reflecting a higher gross profit of $8.4 million primarily due to lower production costs, depreciation, and lower revenue. The decrease in revenue is a result of 39% lower gold equivalent ounces sold in 2020 as compared to 2019 offset by a 27% and 41% higher gold and silver price realized.

​

On a 100% basis, improved performance reflects significantly higher gross profit of $51.0 million in 2020 compared to $34.0 million in 2019 for the reasons as listed above.

​

Higher gross profit in 2020 was due primarily to higher average realized gold and silver prices, offset by lower gold and silver ounces sold. In addition, there were lower production costs applicable to sales and depreciation and depletion expense mainly as a result of lower variable costs associated with the lower production. These all were partially offset by $11.4 million operating costs due to the COVID-19 pandemic in 2020.

​

In 2020, on a 100% basis, MSC generated a cash gross profit of $80.8 million and incurred $22.9 million of development and other capital expenditures, $10.4 million of exploration spending and $30.5 million of other expenditures, with the latter including primarily foreign exchange losses and financing fees. Current and deferred income taxes at December 31, 2020 include current income taxes payable of $4.5 million. MSC paid $0.7 million of dividends to the joint venture partners in 2020 ($0.3 million attributable to us).

Los Azules Segment, Argentina

Los Azules is a copper exploration project located in San Juan, Argentina.

Los Azules Project

During 2020, work continued on preliminary engineering and developing cost estimates to advance the proposed low altitude all year access route. Most of the surveying and staking of the mining rights was completed to be able to consolidate all the mining rights into a single mining group. The Escorpio IV and Mercedes survey were complete in January 2021.

​

In 2021, we expect to continue baseline studies related to flora, fauna, surface water quality and archeology required by the environmental and mining authorities for the current stage of exploration. In addition, the Company is looking at a road study to reduce costs for potential drilling work campaigns.

​

We are currently evaluating two alternatives with regard to Los Azules to realize more value for our shareholders: one is pursuing a joint venture with a senior mining company to bring the project into production; and the other alternative is spinning out the asset into a new public company. Concurrently we are looking at opportunities to improve the economics of Los Azules with ore sorting technologies.

​

The preliminary economic assessment (PEA) for the Los Azules Project, completed and announced in September 2017, is available on our website at www.mcewenmining.com.

NON-GAAP FINANCIAL PERFORMANCE M EASURES

We have included in this report certain non-GAAP performance measures as detailed below. In the gold mining industry, these are common performance measures but do not have any standardized meaning and are considered non-GAAP measures. We believe that, in addition to conventional measures prepared in accordance with GAAP, certain investors use such non-GAAP measures to evaluate the Company’s performance and ability to generate cash flow. We also report these measures to provide investors and analysts with useful information about our underlying costs of operations and clarity over the Company’s ability to finance operations. Accordingly, they are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. There are limitations associated with the use of such non GAAP measures. We compensate for these limitations by relying primarily on our U.S. GAAP results and using the non-GAAP measures supplementally.

The non-GAAP measures are presented for our wholly owned mines and our interest in the San José mine. The GAAP information used for the reconciliation to the non-GAAP measures for our minority interest in the San José mine may be found in Item 8. Financial Statements and Supplementary Data, Note 10, Investment in Minera Santa Cruz S.A. (“MSC”) – San José Mine. The amounts in the tables labeled “49% basis” were derived by applying to each financial statement line item the ownership percentage interest used to arrive at our share of net income or loss during the period when applying the equity method of accounting. We do not control the interest in or operations of MSC and the presentations of assets and liabilities and revenues and expenses of MSC do not represent our legal claim to such items. The amount of cash we receive is based upon specific provisions of the Option and Joint Venture Agreement (“OJVA”) and varies depending on factors including the profitability of the operations.

The presentation of these measures including the minority interest in the San José, has limitations as an analytical tool. Some of these limitations include:

| ● | The amounts shown on the individual line items were derived by applying our overall economic ownership interest percentage determined when applying the equity method of accounting and do not necessarily represent our legal claim to the assets and liabilities, or the revenues and expenses; and

| ● | Other companies in our industry may calculate their cash gross profit, cash costs, cash cost per ounce, all-in sustaining costs, all-in sustaining cost per ounce, average realized price per ounce, and liquid assets differently than we do, limiting the usefulness as a comparative measure.

Cash Gross Profit

Cash gross profit is a non-GAAP financial measure and does not have any standardized meaning. We use cash gross profit to evaluate our operating performance and ability to generate cash flow; we disclose cash gross profit or loss as we believe this measure provides valuable assistance to investors and analysts in evaluating our ability to finance our ongoing business and capital activities. The most directly comparable measure prepared in accordance with GAAP is gross profit or loss. Cash gross profit or loss is calculated by adding depletion and depreciation to gross profit or loss.

The following tables present a reconciliation of cash gross profit or loss to the most directly comparable GAAP measure, gross profit or loss:

Cash Costs and All-In Sustaining Costs

The terms cash costs, cash cost per ounce, all-in sustaining costs, and all-in sustaining cost per ounce used in this report are non-GAAP financial measures. We report these measures to provide additional information regarding operational efficiencies on an individual mine basis, and believe these measures provide investors and analysts with useful information about our underlying costs of operations.

Cash costs consist of mining, processing, on-site general and administrative expenses, community and permitting costs related to current operations, royalty costs, refining and treatment charges (for both doré and concentrate products), sales costs, export taxes and operational stripping costs, but exclude depreciation and amortization (non-cash items). The sum of these costs is divided by the corresponding gold equivalent ounces sold to determine a per ounce amount.

All-in sustaining costs consist of cash costs (as described above), plus accretion of retirement obligations and amortization of the asset retirement costs related to operating sites, environmental rehabilitation costs for mines with no reserves, sustaining exploration and development costs, sustaining capital expenditures and sustaining lease payments. Our all-in sustaining costs exclude the allocation of corporate general and administrative costs. Following is additional information regarding our all-in sustaining costs:

| ● | Sustaining operating costs represent expenditures incurred at current operations that are considered necessary to maintain current annual production at the mine site and include mine development costs and ongoing replacement of mine equipment and other capital facilities. Sustaining capital costs do not include costs of expanding the project that would result in improved productivity of the existing asset, increased existing capacity or extended useful life.

| ● | Sustaining exploration and development costs include expenditures incurred to sustain current operations and to replace reserves and/or resources extracted as part of the ongoing production. Exploration activity performed near-mine (brownfield) or new exploration projects (greenfield) are classified as non-sustaining.

The sum of all-in sustaining costs is divided by the corresponding gold equivalent ounces sold to determine a per ounce amount.

Costs excluded from cash costs and all-in sustaining costs, in addition to depreciation and depletion, are income and mining tax expense, all corporate financing charges, costs related to business combinations, asset acquisitions and asset disposal, and any items that are deducted for the purpose of normalizing items.

The following tables reconcile these non-GAAP measures to the most directly comparable GAAP measure, production costs applicable to sales; the El Gallo Project results are excluded from this reconciliation for 2020 as the economics of residual leaching operations are measured by incremental revenue exceeding incremental costs. Cash costs and all-in sustaining costs include, in addition to current period residual leaching costs, prior-year leach pad inventory costs expensed in the current period, with the latter not relevant on the evaluation of the residual leaching operations. Residual leaching costs for the year ended December 31, 2020 were $11.4 million or $1,409 per gold equivalent ounce. Residual leaching is expected to continue as long as incremental revenues exceed incremental costs. For this reason, we have ceased relying on, and disclosing, cash cost and all-in sustaining cost per gold equivalent ounce as key metrics for the El Gallo Project:

Average realized prices

The term average realized price per ounce used in this report is also a non-GAAP financial measure. We prepare this measure to evaluate our performance against market (London P.M. Fix). Average realized price is calculated as gross sales of gold and silver, less streaming revenue, divided by the number of net ounces sold in the period, less ounces sold under the streaming agreement.

The following table reconciles this non-GAAP measure to the most directly comparable U.S. GAAP measure, revenue from gold and silver sales. Ounces of gold and silver sold for the San José mine are provided to us by MSC.

Liquid assets

The term liquid assets used in this report is also a non-GAAP financial measure. We report this measure to better understand our liquidity in each reporting period.

Liquid assets are calculated as the sum of the Balance Sheet line items of cash and cash equivalents, restricted cash and investments, plus ounces of doré held in precious metals inventories valued at the London PM Fix spot price at the corresponding period. The following table summarizes the calculation of liquid assets as at December 31, 2020 and 2019:

CRITICAL ACCOUNTING ESTIMATES

​

Management’s Discussion and Analysis of Financial Condition and Results of Operations discusses our consolidated financial statements, which have been prepared in conformity with U.S. GAAP. The preparation of these statements requires that we make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. We base these estimates on historical experience and on assumptions that we consider reasonable under the circumstances; however, reported results could differ from those based on the current estimates under different assumptions or conditions. The summary of our significant accounting policies is detailed in Note 2 of the Consolidated Financial Statements.

​

62

Table of Contents

We believe that significant areas requiring the use of management estimates and assumptions relate to environmental reclamation and closure obligations; asset useful lives utilized for depletion, depreciation, amortization and accretion calculations; the fair value of equity investments and asset groups used in impairment testing; recoverable gold in leach pad inventory; current and long-term inventory and mine development capitalization costs; the collectability of value added taxes receivable; fair values of assets and liabilities acquired in business combinations; reserves; valuation allowances for deferred tax assets; income and mining tax provisions and reserves for contingencies and litigation. There are other items within our financial statements that require estimation, but are not deemed to be critical. However, changes in estimates used in these and other items could have a material impact on our financial statements. In the section below we identify estimates critical to the understanding of our financial condition and results of operations and that require the application of significant management judgment.

​

​

Asset Retirement Obligation, reclamation and remediation costs: The Company records the fair value of a liability for an asset retirement obligation (“ARO”) in the period that it is incurred if a reasonable estimate of fair value can be made. The Company prepares estimates of the timing and amounts of expected cash flows when an ARO is incurred, which are updated to reflect changes in facts and circumstances. Estimation of the fair value of AROs requires significant judgment, including amount of cash flows, timing of reclamation, inflation rate and credit risk. Accrued reclamation and closure costs can represent a significant and variable liability on our balance sheet. The company has estimated its liabilities under appropriate accounting guidance, and on at least an annual basis reviews its liabilities. However, the ranges of liability could exceed the liabilities recognized. If substantial damages were awarded, claims were settled, or remediation costs incurred in excess of our accruals, our financial results or condition could be materially adversely affected.

Mineral property interests, Plant and Equipment and Mine Development costs: The Company amortizes its mineral property interests, plant and equipment, and mine development costs using the most appropriate method, which includes the units-of-production method over the estimated life of the mine or ore body based on recoverable ounces to be mined from proven and probable reserves, or the straight-line method over the useful life. The accounting estimates related to amortization are critical accounting estimates because (1) the determination of reserves involves uncertainties with respect to the ultimate geology of its reserves and the assumptions used in determining the economic feasibility of mining those reserves and (2) changes in estimated proven and probable reserves and asset useful lives can have a material impact on net (loss) income.

​

Estimates regarding mine development capitalization costs involve the determination of proven and probable reserves.

Impairment of Long-lived Assets: The Company reviews and evaluates its long-lived assets for impairment when events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Once it is determined that impairment exists, an impairment loss is measured as the amount by which the asset carrying value exceeds its fair value.

For asset groups where an impairment loss is determined using the undiscounted future net cash flows method or discounted future net cash flows method, future cash flows are estimated based on quantities of recoverable mineralized material, expected gold and silver prices (considering current and historical prices, trends and related factors), production levels, operating costs, capital requirements and reclamation costs, all based on life-of-mine plans. The term “recoverable mineralized material” refers to the estimated amount of gold or other commodities that will be obtained after taking into account losses during processing and treatment. The Company’s estimates of future cash flows are based on numerous assumptions and uncertainties. It is possible that actual future cash flows will be significantly different than the estimates, as actual future quantities of recoverable minerals, gold, silver and other commodity prices, production levels and costs of capital are each subject to significant risks and uncertainties.

Stockpiles, Material on Leach Pads, In-process Inventory, Precious Metals Inventory and Materials and Supplies: Stockpiles are measured by estimating the number of tonnes added and removed from the stockpile, an estimate of the contained metals (based on assay data) and the estimated metallurgical recovery rates. Costs are allocated to stockpiles based on current mining costs incurred including applicable overhead relating to mining operations.

Costs are attributed to the mineralized material on leach pads based on current mining costs incurred up to the point of placing the ore on the pad. Costs are removed from the leach pad inventory based on the average cost per estimated recoverable ounce of gold on the leach pad as the gold is recovered. The estimates of recoverable gold on the leach pads are calculated from the quantities of mineralized material placed on the leach pads (measured tonnes added to the leach pads), the grade of mineralized material placed on the leach pads (based on assay data) and a recovery percentage.

63

Table of Contents

Although the quantities of recoverable gold placed on the leach pads are reconciled by comparing the grades of ore placed on the pads to the quantities of gold actually recovered (metallurgical balancing), the nature of the leaching process inherently limits the ability to precisely monitor inventory levels. As a result, the metallurgical balancing process is constantly monitored and the engineering estimates are refined based on actual results over time.

In-process material is measured based on assays of the material from the various stages of processing. Costs are allocated to in-process inventories based on the costs of the material fed into the process attributable to the source material coming from the mines, stockpiles and/or leach pads plus the in-process conversion costs incurred to that point in the process.

Costs are allocated to precious metal inventories based on costs of the respective in-process inventories incurred prior to the refining process plus applicable refining costs.

The assumptions used by the Company to measure metal content during each stage of the inventory conversion process includes estimated recovery rates based on laboratory testing and assaying. The Company periodically reviews its estimates compared to actual experience and revises its estimates when appropriate. The ultimate recovery will not be known until leaching operations cease.

Proven and Probable Reserves: Critical estimates are inherent in the process of determining the Company’s reserves. The Company’s reserves are affected largely by our assessment of future metals prices, as well as by engineering and geological estimates of ore grade, accessibility and production cost. The Company’s assessment of reserves occurs at least annually, and periodically utilizes external audits.

Reserve estimates are used in determining appropriate rates of units-of-production depreciation, with net book value of many assets depreciated over remaining estimated reserves. Reserves are also a key component in forecasts, with which the Company compares future cash flows to current asset values in an effort to ensure that carrying values are reported appropriately. The Company’s forecasts are also used in determining the level of valuation allowances on the Company’s deferred tax assets. Reserves also play a key role in the valuation of certain assets in the determination of the purchase price allocations for acquisitions. Reserves involve many estimates and are not guarantees that the Company will recover the indicated quantities of metals. Changes in reserve estimates could result in material adjustments to the Company’s reserve estimates.

​

Income and Mining Taxes: The Company accounts for income and mining taxes under ASC 740 using the liability method, recognizing certain temporary differences between the financial reporting basis of liabilities and assets and the related tax basis for such liabilities and assets. This method generates either a net deferred income and mining tax liability or asset for the Company, as measured by the statutory tax rates in effect. The Company derives the deferred income and mining tax charge or benefit by recording the change in either the net deferred income and mining tax liability or asset balance for the year. The Company records a valuation allowance against any portion of those deferred income and mining tax assets when it believes, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred income and mining tax asset will not be realized.

​

Accounting for Government Assistance: The Company analogized guidance to account for the COVID-19 relief funds received from the United States Small Business Administration (“SBA”) and the Canada Revenue Agency (“CRA”). The ability to analogize standards from other GAAP sources is provisioned under ASC 105-05-2 when guidance is not provided for certain transactions under US GAAP. The adoption of the standard had a material impact on the financial statements as of December 31, 2020. Under this policy, the Company has recognized the income from the relief funds in the Statement of Operations, as the criteria for recognition of the funds have been met.

FORWARD-LOOKING S TATEMENTS

This report contains or incorporates by reference “forward-looking statements”, as that term is used in federal securities laws, about our financial condition, results of operations and business. These statements include, among others:

| ● | statements about our anticipated exploration results, cost and feasibility of production, production estimates, receipt of permits or other regulatory or government approvals and plans for the development of our properties;

| ● | statements concerning the benefits or outcomes that we expect will result from our business activities and certain transactions that we contemplate or have completed, such as receipt of proceeds, increased revenues, decreased expenses and avoided expenses and expenditures; and

64

Table of Contents

| ● | statements of our expectations, beliefs, future plans and strategies, anticipated developments and other matters that are not historical facts.

These statements may be made expressly in this document or may be incorporated by reference to other documents that we will file with the SEC. Many of these statements can be found by looking for words such as “believes”, “expects”, “anticipates”, “estimates” or similar expressions used in this report or incorporated by reference in this report.

Forward-looking statements and information are based upon a number of estimates and assumptions that, while considered reasonable by management, are inherently subject to significant business, economic and competitive uncertainties, risks and contingencies, and there can be no assurance that such statements and information will prove to be accurate. Therefore, actual results and future events could differ materially from those anticipated in such statements and information.

Included among the forward-looking statements and information which we may provide is production guidance. From time to time the Company provides guidance on operations, based on stand-alone budgets for each operating mine. In developing the mine production portion of the budget, we evaluate a number of factors and assumptions, which include, but are not limited to:

| ● | gold and silver price forecasts;

| ● | average gold and silver grade mined, using a resource model;

| ● | average grade processed by the crushing facility (Gold Bar) or milling facility (San José mine and Black Fox mine);

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

​

Our exposure to market risks includes, but is not limited to, the following risks: changes in foreign currency exchange rates, equity price risks, commodity price fluctuations, credit risk and inflationary risk. We do not use derivative financial instruments as part of an overall strategy to manage market risk.

​

Further, our participation in the joint venture with Hochschild for the 49% interest held at MSC creates additional risks because, among other things, we do not exercise decision-making power over the day-to-day activities at MSC; however, implications from our partner’s decisions may result in us having to provide additional funding to MSC or in a decrease in our percentage of ownership.

​

Foreign Currency Risk

​

In general, the devaluation of non-U.S. dollar currencies with respect to the U.S. dollar has a positive effect on our costs and liabilities which are incurred outside the U.S. while it has a negative effect on our assets denominated in non-U.S. dollar currency. Although we transact most of our business in U.S. dollars, some expenses, labor, operating supplies and property and equipment are denominated in Canadian dollars, Mexican pesos or Argentine pesos.

​

Since 2008, the Argentine peso has been steadily devaluing against the U.S. dollar by 10% to 53% on an annual basis. As noted in the graph below, during 2020 the Argentine peso devalued 29% compared to devaluations of 37% and 53% in 2019 and 2018 respectively. During 2020, the Mexican peso devalued 5% against the US dollar, compared to an increase in value of 5% in 2019 and a decrease in value of 5% in 2018.

​

During 2020, the Canadian dollar increased in value by 2%, compared to the same increase in value of 2% in 2019 and a decrease in value of 5% in 2018.

​

The following table illustrates changes in the value of these currencies compared to the U.S. dollar in the twelve months ended December 31, 2020:

​

​

​

​

67

Table of Contents

The value of cash and cash equivalents denominated in foreign currencies also fluctuates with changes in currency exchange rates. Appreciation of non-U.S. dollar currencies results in a foreign currency gain on such investments and a depreciation in non-U.S. dollar currencies results in a loss. We have not utilized material market risk-sensitive instruments to manage our exposure to foreign currency exchange rates but may do so in the future. We hold minor portions of our cash reserves in non-U.S. dollar currencies.

​

Based on our Canadian cash balance of $10.7 million (C$13.6 million) at December 31, 2020, a 1% change in the Canadian dollar would result in a gain/loss of $0.1 million in the Consolidated Statements of Operations and Comprehensive (Loss) Income. We also hold negligible portions of our cash reserves in Mexican and Argentine pesos, with effect of a 1% change in these respective currencies resulting in gains/losses immaterial for disclosure purposes.

​

Further, we are also subject to foreign currency risk on the fluctuation of the Mexican peso on our VAT receivable balance. As of December 31, 2020, our VAT receivable balance was 18,250,711 Mexican pesos, equivalent to approximately $0.9 million, for which a 1% change in the Mexican peso would have resulted in a gain/loss of less than $0.1 million in the Consolidated Statements of Operations and Comprehensive (Loss) Income.

​

MSC holds a portion of its local cash balances in Argentine pesos and is therefore exposed to the effects of this continued devaluation and also the risk that there may be a sudden severe devaluation of the Argentine peso. A severe devaluation could result in material foreign exchange losses as reported in U.S. dollars.

​

Equity Price Risk

​

We have in the past sought and will likely in the future seek to acquire additional funding by sale of common stock or other equity securities. Movements in the price of our common stock have been volatile in the past and may also be volatile in the future. As a result, there is a risk that we may not be able to sell equity securities at an acceptable price to meet future funding requirements.

​

We have invested and may continue to invest in shares of common stock of other entities in the mining sector. Some of our investments may be highly volatile and lack liquidity caused by lower trading volumes. As a result, we are inherently exposed to fluctuations in the fair value of our investments, which may result in gains or losses upon their valuation.

​

Commodity Price Risk

​

We produce and sell gold and silver, therefore changes in the market price of gold and silver could significantly affect our results of operations and cash flows in the future. Change in the price of gold and silver could materially affect our revenues. Based on our revenues from gold and silver sales of $104.8 million for the year ended December 31, 2020, a 10% change in the price of gold and silver would have had an impact of approximately $10.5 million on our revenues. Changes in the price of gold and silver can also affect the provisionally-priced sales that we make under agreements with refiners and other purchasers of our products. At December 31, 2020, we had no gold or silver sales subject to final pricing. Decreases in the market price of gold or silver can also significantly affect the value of our product inventory, stockpiles and leach pads, and it may be necessary to record a write-down to net realizable value.

​

We have in the past and may in the future hold a portion of our treasury in gold and silver bullion, where the value is recorded at the lower of cost or market. Gold and silver prices may affect the value of any bullion that we hold in treasury.

​

We do not hedge any of our sales and are therefore subject to all changes in commodity prices.

​

Credit Risk

​

We may be exposed to credit loss through our precious metals and doré sales agreements with Canadian financial institutions and refineries if these customers are unable to make payment in accordance with the terms of the agreements. However, based on the history and financial condition of our counterparties, we do not anticipate any of the financial institutions or refineries to default on their obligation. As of December 31, 2020, we do not believe we have any significant credit exposure associated with precious metals and our doré sales agreements.

​

In Mexico, we are exposed to credit loss regarding our VAT taxes receivable if the Mexican tax authorities are unable or unwilling to make payments in accordance with our monthly filings. Timing of collection on VAT receivables is uncertain

68

Table of Contents

as VAT refund procedures require a significant amount of information and follow-up. The risk is mitigated to the extent that the VAT receivable balance can be applied against future income taxes payable. However, at this time we are uncertain when, if ever, our Mexican operations will generate sufficient taxable operating profits to offset this receivable against taxes payable. We continue to face risk on the collection of our VAT receivables, which amount to $0.9 million as at December 31, 2020.

​

In Nevada and Ontario, Canada we are required to provide security to cover our projected reclamation costs. As at December 31, 2020, we have surety bonds of $31.8 million in place to satisfy bonding requirements for this purpose. The bonds have an annual fee of 2.3% of their value. Although we do not believe we have any significant credit exposure associated with these bonds, we are exposed to the risk that the surety bonds may no longer be accepted by the governmental agencies as satisfactory reclamation coverage, in which case we would be required to replace the surety bonding with cash.

​

Interest rate risk

​

Our outstanding debt consists of various equipment leases and the senior secured credit facility. As the debt is at fixed rates, we consider our interest rate risk exposure to be insignificant at this time.

​

Inflationary Risk

​

Argentina has experienced a significant amount of inflation over the last ten years and has now been classified as a highly inflationary economy. ASC 830 defines a hyperinflationary economy as one where the cumulative inflation rate exceeds 100% over the last three years which precede the reporting period. In this scenario, ASC 830 requires companies to change the functional currency of its foreign subsidiaries operating in a highly inflationary economy, to match the company’s reporting currency. In our case, the functional currency of all our Argentine subsidiaries has always been our reporting currency, the U.S. dollar. As such, we do not expect the classification of Argentina’s economy as a highly inflationary economy, to change our financial reporting methodology.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting. The Securities Exchange Act of 1934 defines internal control over financial reporting in Rule 13a-15(f) and 15d-15(f) as a process designed by, or under the supervision of, the Company’s principal executive and principal financial officers and effected by the Company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

| ● | Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;

| ● | Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and the board of directors of the Company; and

| ● | Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The Company’s management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2020. In making this assessment, the Company’s management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework (2013). Based upon its assessment, management concluded that, as of December 31, 2020, the Company’s internal control over financial reporting was effective based upon those criteria.

Ernst & Young LLP, an independent registered public accounting firm, has audited the effectiveness of the Company’s internal control over financial reporting as of December 31, 2020.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of McEwen Mining Inc.

​

Opinion on the Consolidated Financial Statements

​

We have audited the accompanying consolidated balance sheets of McEwen Mining Inc. (the "Company") as of December 31, 2020 and 2019, the related consolidated statements of operations and comprehensive (loss), changes in shareholders’ equity and cash flows for each of the three years in the period ended December 31, 2020, and the related notes (collectively referred to as the “consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its consolidated cash flows for each of the three years in the period ended December 31, 2020 in conformity with U.S. generally accepted accounting principles.

​

Report on Internal Control over Financial Reporting

​

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2020, based on the criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated March 10, 2021 expressed an unqualified opinion on the effectiveness of the Company's internal control over financial reporting.

​

Basis for Opinion

​

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

​

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

​

Critical Audit Matters

​

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

​

​ | ​ |
​ | ​ | Valuation of Inventory at the Gold Bar mine
Description of the Matter | ​ | At December 31, 2020, the carrying value of the Company’s inventory was $31.7 million, of which $15.6 million pertained to leach pad inventory at the Gold Bar gold mine in Nevada, USA. The determination of the net realizable value of the inventory at the Gold Bar mine requires management to make estimates of the expected amount of gold to be recovered. The Company discloses significant judgments, estimates and assumptions in respect of these estimates in Note 8 of the consolidated financial statements.

71

Table of Contents

|  | Auditing management’s estimate of recoverable gold on the leach pads was complex and required specialized knowledge due to the highly judgmental nature of the assumptions. Significant assumptions included the life of mine recovery rate and the grade of mineralized material placed on the leach pad.
How We Addressed the Matter in Our Audit | ​ | We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the quantities of material placed on the pad, the grade determination, the recovery percentage, and the calibration process to assess whether the recovery rate is appropriate. Our substantive audit procedures included, among others, evaluating the reasonableness of the above noted significant assumptions used in the recoverable gold calculation. As each of the key inputs were determined by a specialist, we also assessed the competence and objectivity of management’s specialist by evaluating their professional qualifications, experience, and their use of accepted industry practices. In addition, we evaluated the methodologies used by management’s specialist by understanding the life of mine plan for ore to be placed on the pad, timing of the leaching cycle and the grade determination. We also engaged our internal mining specialist to assess the appropriateness of the Gold Bar gold recovery model and performed a sensitivity analysis to assess the impact of the recovery rate on the ending inventory balance. We reperformed management’s calculation of the leach pad inventory value to verify mathematical accuracy. We assessed the adequacy of the Company’s disclosure in Note 8 to the consolidated financial statements.
​ | ​ | Impairment of Long-lived Assets at the Gold Bar Mine
Description of the Matter | ​ | During the year ended December 31, 2020, the Company recorded an $83.8 million impairment related to Gold Bar plant and equipment and mineral property interests. As disclosed in Note 9 of the consolidated financial statements, the Company reviews and evaluates its long-lived assets for impairment on a quarterly basis or when events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Once it is determined that an impairment exists, an impairment loss is measured as the amount by which the carrying value of the asset or asset group tested for impairment exceeds its fair value. Auditing the Company’s impairment analysis involved a high degree of subjectivity due to the significant estimation uncertainty and judgement applied by management in determining the fair value of the Gold Bar asset group. Significant assumptions included discount rates and long-term gold prices used in the discounted cash flow analysis. In addition, significant judgment and specialized industry knowledge and techniques were required to assess management’s estimated quantities of resource and reserves, the valuation methods applied by management, assumptions of the future operating costs, capital costs and production levels at Gold Bar due to its limited operating history.
How We Addressed the Matter in Our Audit | ​ | We obtained an understanding, evaluated the design, and tested the operating effectiveness of controls over the Company's processes to determine the fair value of the asset group and measure the long-lived asset impairment. This included controls over management's review of the significant assumptions underlying the fair value determination. Our audit procedures included, among others, assessing significant assumptions underlying the fair value determination. We involved our valuation specialist to assist in evaluating the discount rates against current industry and economic trends as well as company-specific risk premiums. We also involved our valuation specialist to compare long-term gold prices against market data including a range of analyst forecasts. We performed sensitivity analyses over changes in the discount rates and long-term gold prices assumptions to the fair value of the Gold Bar asset group. We involved our geology specialist to assist in understanding and evaluating management’s adjustment to the original reserves and resources and factors that the Company considered in the determination of the updated reserves and resources used in the impairment analysis. In addition, we evaluated the competency

72

Table of Contents

|  | and objectivity of management’s qualified persons through consideration of their professional qualifications, experience, and their use of accepted industry practices. To evaluate future operating and capital costs and future productions levels, we compared historical estimates and current estimates of the cost assumptions and production levels used in the undiscounted cash flow against actual results. To test estimates of the fair value of mineralization not included in the life of mine plans, we involved our valuation specialists to assist in inspecting and evaluating management’s analysis supporting the anticipated economics, including comparing the observable relevant transactions to existing operations. We assessed the adequacy of the Company’s disclosure in Note 9 to the consolidated financial statements.

We have served as the Company's auditor since 2016.

Report of Independent Registered Public Accounting Firm

​

To the Shareholders and the Board of Directors of McEwen Mining Inc.

​

Opinion on Internal Control over Financial Reporting

We have audited McEwen Mining Inc.’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, McEwen Mining Inc. (the “Company”) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2020 and 2019, the related consolidated statements of operations and comprehensive (loss), changes in shareholders’ equity and cash flows for each of the three years in the period ended December 31, 2020, and the related notes and our report dated March 10, 2021 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTE 1 NATURE OF OPERATIONS

McEwen Mining Inc. (the “Company”) was organized under the laws of the State of Colorado on July 24, 1979. The Company is engaged in the exploration, development, production and sale of gold and silver and exploration for copper.

The Company operates in the United States, Canada, Mexico and Argentina. The Company owns a 100% interest in the Gold Bar mine in Nevada, the Black Fox gold mine in Ontario, Canada, the El Gallo Project in Sinaloa, Mexico, the Fenix silver-gold project in Sinaloa, Mexico, the Los Azules copper deposit in San Juan, Argentina, and a portfolio of exploration properties in Nevada, Canada, Mexico and Argentina. It also owns a 49% interest in Minera Santa Cruz S.A. (“MSC”), owner of the producing San José silver-gold mine in Santa Cruz, Argentina, which is operated by the joint venture majority owner, Hochschild Mining plc.

​

During the year (Note 14) and subsequent to year end (Note 23) the Company closed on $64.4 million in gross proceeds from equity financings. As a result of this, the Company believes it has sufficient liquidity along with funds generated from ongoing operations, to fund anticipated cash requirements for operations, capital expenditures and working capital purposes. As a result, the previously disclosed going concern note has been removed, as substantial doubt no longer exists regarding the Company’s ability to meet its obligations as they become due within one year after the date that the financial statements are issued.

NOTE 2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Use of Estimates:

The Company’s consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of the Company’s consolidated financial statements requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions relate to environmental reclamation and closure obligations; asset useful lives utilized for depletion, depreciation, amortization and accretion calculations; fair value of equity investment and the impairment test; recoverable gold in leach pad inventory; current and long-term inventory; mine development capitalization costs; the collectability of value added taxes receivable; reserves; valuation allowances for deferred tax assets; income and mining tax provisions; reserves for contingencies and litigation and costs and relief funds related to COVID-19. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ significantly from these estimates.

References to “C$” refer to Canadian currency.

COVID-19:

On March 11, 2020, the World Health Organization (“WHO”) declared the COVID-19 virus a global pandemic. As a result of the pandemic, many jurisdictions, including the United States, Canada, Mexico and Argentina, instituted restrictions on travel, public gatherings, and certain business operations. Even absent of government-mandated shut downs, the Company was required to temporarily suspend operations at its mines to protect the health and safety of its employees and contractors. This resulted in temporary shutdowns of all or a portion of operations at all of the Company’s mine sites at the start of Q2 2020. Since that date, all of the Company’s operations, have successfully recommenced operations. During the fourth quarter of 2020, operations at the San José mine were briefly suspended as a result of a significant increase in infections in the Santa Cruz region.

​

The temporary shutdowns adversely impacted the Company’s operations, cash flow, and liquidity in the second quarter of 2020 and some of these effects continued into the third and fourth quarters. In addition to the adverse effect on revenue, the Company incurred costs in connection with the shutdowns and subsequent ramp-up. This, in turn, adversely affected the Company’s liquidity. The long-term impact of the COVID-19 outbreak on the Company’s results of operations, financial position and cash flows will depend on future developments, including the duration and spread of the outbreak, the availability and distribution of vaccinations, and government advisories and restrictions. These developments and the impact of COVID-19 on the global financial markets, the overall economy and the Company are highly uncertain and cannot be predicted. Achieving and maintaining normal operating capacity is also dependent on the continued availability of supplies, which is out of the Company’s control. If the financial markets and/or the overall economy continue to be impacted, the Company’s results of operations, financial position and cash flows may be further affected. As the situation continues to evolve, the Company will continue to closely monitor market conditions and respond accordingly. The Company has completed various scenario planning analyses to consider potential impacts of COVID-19 on its business, including volatility in commodity prices, temporary disruptions and/or curtailments of operating activities (voluntary or involuntary).

Basis of Consolidation:

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated. Investments over which the Company exerts significant influence but does not control through majority ownership are accounted for using the equity method, as described in Investments, below.

Cash and Cash Equivalents and Restricted Cash:

The Company considers cash in banks, deposits in transit, and highly liquid term deposits with original maturities of three months or less at the date of acquisition to be cash and cash equivalents. Because of the short maturity of these instruments, the carrying amounts approximate their fair value. The Company classifies Restricted cash between short term and long term based on the restrictions.

Investments:

The Company accounts for investments over which the Company exerts significant influence but does not control through majority ownership using the equity method of accounting pursuant to ASC Topic 323, Investments – Equity Method and Joint Ventures. Under the equity method, the Company’s investment is initially recognized at cost in the Consolidated Balance Sheet and subsequently increased or decreased to recognize the Company's share of income and losses of the investee, dividends received from the investee and for impairment losses after the initial recognition date. The Company's share of income and losses of the investee and impairment losses are recognized in the Consolidated Statements of Operations and Comprehensive (Loss) (“Statement of Operations”) during the period. Refer to Impairment of Long-lived Assets for the Company’s policy on impairment.

The Company’s investments in marketable equity securities and warrants are measured at fair value at each period end with changes in fair value recognized in net (loss) income in the Statement of Operations in accordance with ASU 2016-01.

Value Added Taxes Receivable:

In Mexico, Argentina, and Canada, value added taxes (“VAT” and “HST”, respectively) are assessed on purchases of materials and services and sales of products. Businesses are generally entitled to recover the taxes they have paid related to purchases of materials and services, either as a refund or as a credit against future taxes payable.

Stockpiles, Material on Leach Pads, In-process Inventory, Precious Metals Inventory and Materials and Supplies: Stockpiles, material on leach pads, in-process inventory, precious metals inventory and materials and supplies (collectively, “Inventories”) are accounted for using the weighted average cost method and are carried at the lower of average cost or net realizable value. Net realizable value represents the estimated future sales price of the product based

MCEWEN MINING INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2020

(tabular amounts are in thousands of U.S. dollars, unless otherwise noted) (Continued)

​

on current and long-term metals prices, less the estimated costs to complete production and bring the product to a saleable form. Write-downs of Inventories resulting from net realizable value impairments are reported as a component of production costs applicable to sales. The current portion of Inventories is determined based on the expected amounts to be processed and/or recovered within the next twelve months of the balance sheet date, with the remaining portion, if any, classified as long-term.

Stockpiles represent mineralized material extracted from the mine and available for processing. Stockpiles are measured by estimating the number of tonnes added and removed from the stockpile, an estimate of the contained metals (based on assay data) and the estimated metallurgical recovery rates. Costs are allocated to stockpiles based on current mining costs incurred including applicable overhead relating to mining operations. Material is removed from the stockpile at an average cost per tonne.

Mineralized material on leach pads is the material that is placed on pads where it is treated with a chemical solution that dissolves the gold contained in the mineralized material over a period of time. Costs are attributed to the mineralized material on leach pads based on current mining costs and processing costs incurred related to the ore on the pad. Costs are removed from the leach pad inventory based on the average cost per estimated recoverable ounce of gold on the leach pad as the gold is recovered. The estimates of recoverable gold on the leach pads are calculated from the quantities of mineralized material placed on the leach pads (measured tonnes added to the leach pads), the grade of mineralized material placed on the leach pads (based on assay data) and a recovery percentage.

While the quantities of recoverable gold placed on the leach pads are periodically reconciled by comparing the grades of ore placed on the pads to the quantities of gold actually recovered (metallurgical balancing), the nature of the leaching process inherently limits the ability to precisely monitor inventory levels. As a result, the metallurgical balancing process is constantly monitored, and the engineering estimates are refined based on actual results over time.

In-process inventories represent materials that are currently in the process of being converted to a saleable product. In-process material is measured based on assays of the material from the various stages of processing. Costs are allocated to in-process inventories based on the costs of the material fed into the process attributable to the source material coming from the mines, stockpiles and/or leach pads plus the in-process conversion costs incurred to that point in the process.

Precious metal inventories include gold and silver doré and bullion that is unsold and held at the Company’s or the refinery’s facilities. Costs are allocated to precious metal inventories based on costs of the respective in-process inventories incurred prior to the refining process plus applicable refining costs.

Materials and supplies inventories are comprised of chemicals, reagents, spare parts and consumable parts used in operating and other activities. Cost includes applicable taxes and freight.

Proven and Probable Reserves:

The definition of proven and probable reserves is set forth in SEC Industry Guide 7 (Guide 7). Proven reserves are reserves for which (a) quantity is computed from dimensions revealed in outcrops, trenches, workings or drill holes, grade and/or quality are computed from the results of detailed sampling and (b) the sites for inspection, sampling and measurement are spaced so closely and the geological character is so well defined that size, shape, depth and mineral content of the reserves are well-established. Probable reserves are reserves for which quantity and grade and/or quality are computed from information similar to that used for proven (measured) reserves, but the sites for inspection, sampling, and measurement are farther apart or are otherwise less adequately spaced. The degree of assurance, although lower than that for proven (measured) reserves, is high enough to assume continuity between points of observations.

Mineral Property Interests and Plant and Equipment:

Mineral property interests: Mineral property interests represent capitalized expenditures related to the development of mineral properties and expenditures arising from property acquisitions. The amount capitalized for an acquired mineral

81

(tabular amounts are in thousands of U.S. dollars, unless otherwise noted) (Continued)

​

property represents its fair value at the time of acquisition, either as an individual asset purchase or as a part of a business combination.

Development costs include engineering and metallurgical studies, drilling and other related costs to delineate an ore body, and the removal of overburden to initially expose an ore body at open pit surface mines (“pre-stripping”) and building of access paths and other infrastructure to gain access to the ore body at underground mines. Development costs are charged to operations in the year incurred as Advanced Projects until proven and probable reserves as defined by Guide 7 have been met, after which they are capitalized. Where multiple open pits exist at a mine, pre-stripping costs are capitalized separately to each pit. Production commences when saleable minerals, beyond a de minimis amount, are produced.

During the production phase of a mine, costs incurred to provide access to reserves and resources that will be produced in future periods that would not have otherwise been accessible are capitalized and included in the carrying amount of the related mineral property interest.

Drilling and related costs are capitalized for an ore body where proven and probable reserves exist and the activities are directed at obtaining additional information, providing greater definition of the ore body or converting non-reserve mineralization to proven and probable reserves and the benefit is expected to be realized over a period beyond one year. All other drilling and related costs are expensed as incurred as Exploration or Advanced Projects. Exploration costs include costs incurred to identify new mineral resources, evaluate potential resources, and convert mineral resources into proven and probable reserves. However, drilling costs specifically incurred for the purpose of operational ore control during the production stage rather than obtaining additional information on the ore body are expensed and allocated to inventory costs and then included as a component of production costs applicable to sales as the revenue from the sale of inventory occurs.

Mineral property interests are amortized upon commencement of production on a unit-of-production basis over proven and probable reserves, as defined by Guide 7. When a property does not contain mineralized material that satisfies the definition of proven and probable reserves, the amortization of the capitalized costs is charged to expense based on the most appropriate method, which includes straight-line method and units-of-production method over the estimated useful life of the mine, as determined by internal mine plans.

Plant and Equipment: For properties where the Company has established proven and probable reserves as defined by Guide 7, expenditures for plant and equipment and expenditures that extend the useful lives of existing plant and equipment are capitalized and recorded at cost. The cost capitalized for plant and equipment includes borrowing costs incurred that are attributable to qualifying plant and equipment. Plant and equipment are depreciated using the straight-line method over the estimated productive life of the asset.

For properties where the Company did not establish proven and probable reserves as defined by Guide 7, substantially all costs, including design, engineering, construction, and installation of equipment are expensed as incurred, unless the equipment has alternative uses or significant salvage value, in which case the equipment is capitalized at cost.

Construction-in-progress (“CIP”) costs: Assets under construction are capitalized as construction-in-progress until the asset is available for its intended use, at which point costs are transferred to the appropriate category of plant and equipment or mineral property interest and amortized. The cost of construction-in-progress comprises the purchase price of the asset and any costs directly attributable to bringing it into working condition for its intended use.

Impairment of Long-Lived Assets:

The Company reviews and evaluates its long-lived assets for impairment on a quarterly basis or when events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Once it is determined that impairment exists, an impairment loss is measured as the amount by which the asset carrying value exceeds its estimated fair value. For the purpose of recognition and measurement of impairment, the Company groups its long-lived assets by specific mine or project, as this represents the lowest level for which identifiable cash flows exist.

MCEWEN MINING INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2020

(tabular amounts are in thousands of U.S. dollars, unless otherwise noted) (Continued)

​

For asset groups where an impairment indicator is identified, an impairment loss is determined if the carrying amount of the asset group exceeds the recoverable amount as determined using the undiscounted future net cash flows. An impairment loss, if any, is the amount by which the carrying amount exceeds the discounted future net cash flows. It is possible that actual future cash flows will be significantly different than the estimates, as actual future quantities of recoverable minerals, gold, silver and other commodity prices, production levels and costs of capital are each subject to significant risks and uncertainties.

For asset groups where the Company is unable to determine a reliable estimate of future net cash flows, the Company adopts a market approach to estimate fair value by using a combination of observed market value per square mile and observed market value per ounce or pound of estimated mineralized material based on comparable transactions.

Asset Retirement Obligation (“ARO”), Reclamation and Remediation Costs:

Provisions for environmental rehabilitation are made in respect of the estimated future costs of closure and restoration and rehabilitation costs (which include the dismantling and demolition of infrastructure, removal of residual materials and remediation of disturbed areas) in the accounting period when the related environmental disturbance occurs. The associated asset retirement costs, including periodic adjustments, if any, are capitalized as part of the carrying amount of the long-lived asset when proven or probable reserves exist or if they relate to an acquired mineral property interest; otherwise, the costs are charged to the operations. Periodic accretion is recorded to ARO and charged to operations.

The fair value of an ARO is measured by discounting the expected cash flows adjusted for inflation, using a credit-adjusted risk free rate of interest. The Company prepares estimates of the timing and amounts of expected cash flows when an ARO is incurred, which are updated to reflect changes in facts and circumstances. Estimation of the fair value of AROs requires significant judgment, including amount of cash flows, timing of reclamation, inflation rate and credit risk.

Lease Accounting:

Contracts are analyzed to identify whether the contract contains an operating or financing lease according to ASC 842, adopted by the Company effective January 1, 2019 using the modified retrospective transition method. If a contract is determined to contain a lease, the Company will include lease payments (the lease liability) and the right-of-use asset (“ROU”) representing the right to the underlying asset for the lease term within the Consolidated Balance Sheets. Lease liabilities are disclosed as a distinct line item within the Consolidated Balance Sheets, whereas, the ROU asset is included in mineral property interests and plant and equipment. Related depreciation and amortization expense and interest expense for finance leases, and rent expense for operating leases is recorded within the Statement of Operations. For leases with a term of twelve months or less, an accounting policy election is made to not recognize lease assets and lease liabilities. The Company has elected to account for non-lease components as part of the lease component to which they relate.

Operating and ROU asset balances and lease liabilities are recognized at the commencement date of the lease based on the present value of the future lease payments over the lease term. The Company utilizes the incremental borrowing rate (“IBR”) in determining the present value of the future lease payments. IBR represents the rate of interest that a lessee would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term in a similar economic environment. Each lease’s IBR is determined by using the average bond yield ratings for comparable companies.

Revenue Recognition:

Revenue consists of proceeds received and expected to be received for the Company’s principal products, gold and silver. Revenue is recognized when title to gold and silver passes to the buyer and when collectability is reasonably assured. Title passes to the buyer based on terms of the sales contract, usually upon delivery of the product. Product pricing is determined under the sales agreements which are referenced against active and freely traded commodity markets, for example, the London Bullion Market for both gold and silver, in an identical form to the product sold. Gold and silver doré produced from the San José mine is sold at the prevailing spot market price based on the London A.M. fix, while concentrates are sold at the prevailing spot market price based on either the London P.M. fix or average of the London A.M. and London P.M. fix depending on the sales contract. Concentrates are provisionally priced, whereby the selling price is subject to final

​

adjustments at the end of a period ranging from 30 to 90 days after delivery to the customer. The final price is based on the market price of the precious metal content at the relevant quotation point stipulated in the contract. Due to the time elapsed between shipment and the final settlement with the buyer, MSC must estimate the prices at which sales of metals will be settled. At the end of each financial reporting period, previously recorded provisional sales are adjusted to estimated settlement metals prices based on relevant forward market prices until final settlement with the buyer.

In addition to selling refined bullion at spot, the Company has doré purchase agreements in place with financial institutions and refineries. Under the agreements, the Company has the option to sell approximately 90% of the gold and silver contained in doré bars prior to the completion of refining by the third party refiner. Revenue is recognized when the Company has provided irrevocable instructions to the refiner to transfer to the purchaser the refined ounces sold upon final processing outturn, and when payment of the purchase price for the purchased doré or bullion has been made in full by the purchaser. There is no judgement involved in revenue recognition as revenue is recognized when payment has been made by the purchaser and the product has been delivered.

Foreign Currency:

The functional currency for the Company’s operations is the U.S. dollar. All monetary assets and liabilities denominated in a currency which is not the U.S. dollar are translated at current exchange rates at each balance sheet date and the resulting adjustments are included in a separate line item under other income (expense). Revenues and expenses in foreign currencies are translated at the average monthly exchange rates for the corresponding period.

​

Stock-Based Compensation:

The Company accounts for stock options at fair value as prescribed in ASC 718. The Company estimates the fair value of each stock option at the grant date by using the Black-Scholes option-pricing model and provides for expense recognition over the service period, if any, of the stock option. The Company’s estimates may be impacted by certain variables including, but not limited to, stock price volatility, employee stock option exercise behavior and estimates of forfeitures.

Flow-Through Common Shares:

Current Canadian tax legislation permits mining entities to issue flow-through common shares to investors by which the deductions for tax purposes related to resource exploration and evaluation expenditures may be claimed by investors instead of the entity, subject to a renouncement process. Under ASC 740, proceeds from the issuance of flow-through common shares are allocated first to the common stock based on the underlying quoted price of shares and the residual amount is allocated to the sale of tax benefits, which is classified as a liability. In the future, as the Company incurs qualifying exploration and evaluation expenditures to fulfill its obligation, the liability is drawn down and the sale of tax benefits is recognized in the Statement of Operations as a reduction of deferred tax expense.

Income and Mining Taxes:

The Company accounts for income and mining taxes under ASC 740 using the liability method, recognizing certain temporary differences between the financial reporting basis of liabilities and assets and the related tax basis for such liabilities and assets. This method generates either a net deferred income and mining tax liability or asset for the Company, as measured by the statutory tax rates in effect. The Company derives the deferred income and mining tax charge or benefit by recording the change in either the net deferred income and mining tax liability or asset balance for the year. The Company records a valuation allowance against any portion of those deferred income and mining tax assets when it believes, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred income and mining tax asset will not be realized.

Comprehensive (Loss) Income:

In addition to net income or loss, comprehensive income or loss is included in changes in equity during a period.

​

Per Share Amounts:

Basic income or loss per share is computed by dividing income or loss available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted income per share reflects the potential dilution of securities that could share in the earnings of the Company and is computed in accordance with the treasury stock method based on the average number of common shares and dilutive common share equivalents outstanding. Only those instruments that result in a reduction in income per share are included in the calculation of diluted (loss) income per share.

Loans and Borrowings:

Borrowings are recognized initially at fair value, net of financing costs incurred, and subsequently measured at amortized cost. Any difference between the amounts originally received and the redemption value of the debt is recognized in the Statements of Operations over the period to maturity using the effective interest method. Borrowing costs directly attributable to the acquisition, construction or production of a qualifying asset (i.e. an asset that necessarily takes a substantial period of time to get ready for its intended use or sale) are capitalized as part of the cost of the asset. All other borrowing costs are expensed in the period they occur.

Fair Value of Financial Instruments:

Fair value accounting establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:

Loans and borrowings: Borrowings are recognized initially at fair value, net of financing costs incurred, and subsequently measured at amortized cost. Any difference between the amounts originally received and the redemption value of the debt is recognized in the Consolidated Statement of Operations and Comprehensive (Loss) Income over the period to maturity using the effective interest method. Fair Value of Financial Instruments: Fair value accounting, as prescribed in ASC Section 820, utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below: | ​
Level 1 | Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
Level 2 | Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and
Level 3 | Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity).

Recently Adopted Accounting Pronouncements

Accounting for Government Assistance: In June 2020, the Company analogized guidance to account for the COVID-19 relief funds received from the United States Small Business Administration (“SBA”) and the Canada Revenue Agency (“CRA”). The ability to analogize standards from other GAAP sources is provisioned under ASC 105-05-2 when guidance is not provided for certain transactions under US GAAP. The adoption of the standard had a material impact on the financial statements as of December 31, 2020 with no impact noted in prior years. Under this policy, the Company has recognized the income from the relief funds in the Statement of Operations, as the criteria for recognition of the funds have been met.

Changes to the Disclosure Requirements for Fair Value Measurement: In August 2018, the FASB issued ASU 2018- 13, “Fair Value Measurement (ASC 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement”. This update modifies the disclosure requirements for fair value measurements by removing, modifying, or adding disclosures. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019. The adoption of ASU 2018-13 in 2020 did not have a material impact on the Company’s financial statements and related disclosures.

Recently Issued Accounting Pronouncements

Income Taxes: In December 2019, FASB issued ASU 2019-12 “Income Taxes (Topic 740).” ASU 2019-12 simplifies the accounting for income taxes by reducing complexity in accounting standards. The update to the accounting standard is effective for the Company for fiscal years beginning after December 15, 2020, with early adoption permitted. The Company is currently evaluating the effect of this amendment and the impact it may have on the Company’s consolidated financial statements.

NOTE 3 OPERATING SEGMENT REPORTING

McEwen Mining is a mining and minerals production and exploration company focused on precious metals in the United States, Canada, Mexico, and Argentina. The Company’s chief operating decision maker (“CODM”) reviews the operating results, assesses performance and makes decisions about allocation of resources to these segments at the geographic region level or major mine/project where the economic characteristics of the individual mines or projects within a geographic region are not alike. As a result, these operating segments also represent the Company’s reportable segments. The Company’s business activities that are not considered operating segments are included in General and Administrative and other and are provided in this note for reconciliation purposes.

The CODM reviews segment income or loss, defined as gold and silver sales less production costs applicable to sales, depreciation and depletion, advanced projects, and exploration costs, for all segments except for the MSC segment which is evaluated based on the attributable equity income or loss pickup. Gold and silver sales and production costs applicable to sales for the reportable segments are reported net of intercompany transactions.

Production costs applicable to sales for the El Gallo project were $15.7 million for the year ended December 31, 2020 (in the year ended December 31, 2019 - $18.5 million) and included $8.4 million of residual leaching spending in the year, net of $3.0 million capitalized in inventory (in the year ended December 31, 2019 - $8.2 million, net of $3.4 million capitalized in inventory) with the remaining balance of production costs applicable to sales of $7.3 million (in the year ended December 31, 2019 - $10.3 million) corresponds to opening leach pad inventory costs that are included as production costs applicable to sales.

Capital expenditures include costs capitalized in mineral property interests and plant and equipment in the respective periods.

Significant information relating to the Company’s reportable operating segments for the periods presented is summarized in the tables below:

Costs incurred while operations were suspended total $0.9 million at Gold Bar and $0.6 million at Black Fox during the twelve months ended December 31, 2020. In addition, the Gold Bar operational shutdown was extended while the Company conducted a thorough review of its resource and mine plan during Q2 2020. Upon completion of this review, the Company commenced a controlled and phased ramp up of operations through the remainder of the second quarter. Costs incurred due to the resource review were $0.5 million.

​

In response to COVID-19, the United States and Canadian governments enacted significant relief measures to support businesses directly and adversely impacted by the pandemic. During 2020, the Company secured $1.9 million of relief from the US government under the paycheck protection (“PPP”) program. The funds are fully forgivable as long as sufficient eligible expenditures are incurred in a 24 week period. The income from the PPP program is recognized on a systematic basis as eligible forgivable expenditures are incurred. As at December 31, 2020, the full amount has been recognized as other income, as the Company is reasonably assured that it is in compliance with the forgiveness criteria of incurring the eligible expenses for forgiveness within the required time frame. The Company also secured $4.5 million of government relief in Canada through the Canadian Emergency Wage Subsidy program all of which has been recognized in other income.

Total mineral property interests | ​ | ​ | ​ | ​ | ​ | $ | 280,118 | ​ | $ | 311,220 | ​

​

Black Fox and Gold Bar mineral property interest are depleted based on the units of production method from production commencement date over the estimated proven and probable reserves.

The El Gallo Project is depleted and depreciated using the straight line or units-of-production method over the stated mine life, as the project does not have proven and probable reserves compliant with Guide 7.

The definition of proven and probable reserves is set forth in the Guide 7. If proven and probable reserves exist at the Company’s properties, the relevant capitalized mineral property interests and asset retirement costs are charged to expense based on the units of production method upon commencement of production. The Company’s Gold Bar, Black Fox and San José properties have proven and probable reserves estimated in accordance with SEC Industry Guide 7.

The Company conducts a review of potential triggering events for impairment for all its mineral projects on a quarterly basis or when events or changes in circumstances indicate that the related carrying amounts may not be recoverable.

As part of the analysis conducted in Q1 2020, the Company determined that indicators of impairment existed for the long-lived assets at the Gold Bar mine and that the long-lived assets at the Gold Bar mine were likely not recoverable on an undiscounted basis. The fair value of the Gold Bar mine was estimated using the discounted cash flow method, coupled with an in-situ resource multiple for mineralized material not included in the life of mine plan. Future cash flows were estimated based on estimated quantities of recoverable mineralized material, expected gold prices, estimated production levels, operating costs, capital requirements and reclamation costs, all based on the life-of-mine plan using the preliminary estimated resources. The in-situ resource multiple applied to the mineralized material not included in the life-of-mine plan was estimated by evaluating observable market transactions. The Company concluded that the carrying value of the long-lived assets at the Gold Bar mine was impaired and recorded a non-cash impairment charge reducing plant and equipment and mineral property interests by the amount of $83.8 million.

​

As of December 31, 2020 no further indicators of impairment have been noted for Gold Bar.

The following table sets forth a summary of the quantitative and qualitative information related to the unobservable inputs used in the calculation of the Company’s non-recurring Level 3 fair value measurement of the Gold Bar mine:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​
​ | ​ | Date of Fair Value Measurement | ​ | Valuation Technique | ​ | Unobservable Input | ​ | Range/ Weighted Average
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Gold Bar Mine | ​ | March 31, 2020 | ​ | Discounted Cash Flow | ​ | Discount Rate | ​ | 9%
​ | ​ | ​ | ​ | ​ | ​ | Long Term Gold Price | ​ | $1,430/oz
​ | ​ | ​ | ​ | ​ | ​ | United States Inflation Index | ​ | 2%

​

The estimated future cash flows are based on numerous assumptions and uncertainties. It is possible that actual future cash flows will be significantly different than the estimates, as actual future quantities of recoverable minerals, gold prices, production levels and costs of capital are each subject to significant risks and uncertainties.

NOTE 12 LONG-TERM DEBT

On August 10, 2018, the Company finalized a $50.0 million senior secured three year term loan facility with Royal Capital Management Corp., as administrative agent, and the lenders party thereto. Interest on the loan accrued at the rate of 9.75% per annum with interest due monthly and the loan was collateralized by a lien on certain of the Company’s and its subsidiaries’ assets.

On June 25, 2020, the Company entered into an Amended and Restated Credit Agreement (“ARCA”) which refinanced the outstanding $50 million and which terms differed in material respects from the original loan as follows:

​

| ● | Sprott Private Resource Lending II (Collector), LP replaced Royal Capital Management Corp. as the administrative agent.

| ● | Sprott Private Resource Lending II (Collector), LP replaced certain lenders. An affiliate of Robert McEwen remains as a lender.

| ● | Scheduled repayments of the principal are extended by two years. Monthly repayments of principal in the amount of $2.0 million are due beginning on August 31, 2022 and continuing for 12 months, followed by a final principal payment of $26.0 million plus any accrued interest on August 31, 2023.

| ● | The minimum working capital maintenance requirement was reduced from $10.0 million under the original term loan to $nil at June 30, 2020 to December 31, 2020 and from $10.0 million to $2.5 million at March 31, 2021 to the end of 2021. The working capital requirement increases to $5.0 million for March 31, 2022, $7.0 million for June 30, 2022, and $10 million for September 30, 2022 and thereafter.

| ● | The Company issued 2,091,700 shares valued at $1,875,000 to the lenders as bonus interest, accounted for as a financing cost. The value of the shares plus the unamortized costs of the original term loan will be amortized over the modified term of the loan.

NOTE 14 SHAREHOLDERS’ EQUITY

Equity Issuances

Flow-Through Shares Issuance

On December 31, 2020, the Company issued an additional 7,669,900 flow-through common shares priced at $1.28 per share for gross proceeds of $9.8 million. The purpose of this offering was to fund exploration activities on the Company’s properties in the Timmins region of Canada. The total proceeds were allocated between the sale of tax benefits and the sale of common shares. No issuance costs were incurred as part of this issuance. Proceeds of $9.8 million were allocated between the sale of tax benefits in the amount of $2.1 million and the sale of common shares in the amount of $7.7 million.

On September 10, 2020, the Company issued 6,298,166 flow-through common shares priced at $1.65 per share for gross proceeds of $10.4 million. The purpose of this offering was to fund exploration activities on the Company’s properties in the Timmins region of Canada. The total proceeds were allocated between the sale of tax benefits and the sale of common shares. The total issuance costs related to the issuance of the flow-through shares was $0.6 million, which are accounted for as a reduction to the common shares. The net proceeds of $9.8 million were allocated between the sale of tax benefits in the amount of $2.0 million and the sale of common shares in the amount of $7.8 million.

The Company is required to spend flow-through share proceeds on flow-through eligible Canadian exploration expenditures (“CEE”) as defined by subsection 66(15) of the Income Tax Act (Canada). To date, the Company has incurred a total of $1.9 million in eligible CEE. The Company expects to fulfill its CEE commitments by the end of 2022.

June 2020 Amended and Restated Credit Agreement

Pursuant to the ARCA executed on June 25, 2020, the Company issued 2,091,700 shares of common stock to the lenders as consideration for the maintenance, continuation, and the extension of the maturity date of the loan. The Company valued the shares at $1.9 million.

Shares Issued for Acquisition of Mineral Property Interests

During the year ended December 31, 2020, the Company issued a total of 53,600 shares of common stock for the acquisition of mineral interests adjacent to Gold Bar, valued at $0.1 million (year ended December 31, 2019 - issued 353,570 shares of common stock for the acquisition of mineral interests adjacent to Gold Bar).

November 2019 Offering

On November 20, 2019 (the “November Offering”), the Company issued 37,750,000 Units at $1.325 per Unit, for net proceeds of $46.6 million (net of issuance costs of $3.5 million). Each Unit consisted of one share of common stock and one-half of one warrant. Each whole warrant is exercisable at any time for one share of common stock of the Company at a price of $1.7225, subject to customary adjustments, expiring five years from the date of issuance. The warrants provide for cashless exercise under certain conditions. The warrants under the November Offering are listed for trading on an over the counter market.

The Company concluded that both common stock and warrants are equity-linked financial instruments and should be accounted for permanently in the shareholders’ equity section in the Consolidated Balance Sheets, with no requirement to subsequently revalue any of the instruments. Of the net proceeds of $46.6 million, $37.3 million was allocated to common stock and $9.3 million was allocated to warrants, based on their relative fair values at issuance.

The Company used the Black-Scholes pricing model to determine the fair value of warrants issued in connection with the November Offering using the following assumptions:

All 21,706,250 warrants issued under the November Offering remain outstanding and unexercised as at December 31, 2020.

March 2019 Offering

On March 29, 2019, the Company issued 14,193,548 Units at $1.55 per Unit, for net proceeds of $20.3 million (net of issuance costs of $1.7 million). Each Unit consisted of one share of common stock and one-half of one warrant. Each whole warrant is exercisable at any time for one share of common stock at a price of $2.00, subject to customary adjustments, expiring three years from the date of issuance. The warrants issued under the offering are not listed for trading.

​

On March 29, 2019, the Company also issued 1,935,484 Subscription Receipts at $1.55 per Subscription Receipt to certain executive officers, directors, employees and consultants. Upon shareholder and NYSE approval on May 23, 2019, the Subscription Receipts were converted into 1,935,484 Units for net proceeds of $2.6 million (net of issuance costs of $0.4 million). All Units issued under the offering have identical terms.

At-the-Market (“ATM”) Offering

Pursuant to an equity distribution agreement dated November 8, 2018, the Company was permitted to offer and sell from time to time shares of its common stock having an aggregate offering price of up to $90.0 million, with the net proceeds to fund working capital and general corporate purposes. During the three months ended March 31, 2019, the Company issued an aggregate of 1,010,545 shares of common stock for proceeds of $1.9 million. The Company terminated the agreement on March 13, 2019.

Stock Options

The Company’s Amended and Restated Equity Incentive Plan (“Plan”) allows for equity awards to be granted to employees, consultants, advisors, and directors. The Plan is administered by the Compensation Committee of the Board of Directors (“Committee”), which determines the terms pursuant to which any award is granted. The Committee may delegate to certain officers the authority to grant awards to certain employees (other than such officers), consultants and advisors. The number of shares of common stock reserved for issuance thereunder is 17.5 million shares, including shares issued under the Plan before it was amended, with no more than 1 million shares subject to grants of options to an individual in a calendar year. The Plan provides for the grant of incentive options under Section 422 of the Internal Revenue Code (the “Code”), which provide potential tax benefits to the recipients compared to non-qualified options. At December 31, 2020, 2,308,550 awards were authorized and available for issuance under the Plan (December 31, 2019 – 4,221,023 awards).

During the year ended December 31, 2020, 135,000 shares of common stock (December 31, 2019 – 535,000) were issued upon exercise of stock options under the Plan, at a weighted average exercise price of $1.02 (2019 – $1.02) per share for proceeds of $0.1 million (2019 – $0.5 million).

Stock options have been granted to key employees, directors and consultants under the Plan. Options to purchase shares under the Plan were granted at or above market value of the common stock as of the date of the grant. During the year ended December 31, 2020, the Company granted stock options to certain employees and directors for an aggregate of 5.1 million shares of common stock (2019 – 3.1 million, 2018 – 0.4 million) at a weighted average exercise price of $1.22 per share (2019 – $1.73, 2018 – $1.90). The options vest equally over a three-year period if the individuals remain affiliated with the Company (subject to acceleration of vesting in certain events) and are exercisable for a period of five years from the date of grant.

​

The fair value of the options granted under the Plan was estimated at the date of grant, using the Black-Scholes option-pricing model, with the following weighted-average assumptions:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | ​ | 2020 |  | ​ | 2019 |  | ​ | 2018
Risk-free interest rate | ​ | ​ | .157% to .322% | ​ | ​ | 1.45% to 1.87% | ​ | ​ | 2.67% to 2.89%
Dividend yield | ​ | ​ | 0.00% | ​ | ​ | 0.00% | ​ | ​ | 0.36% to 0.53%
Volatility factor of the expected market price of common stock | ​ | ​ | 59% | ​ | ​ | 58% | ​ | ​ | 63% to 64%
Weighted-average expected life of option | ​ | ​ | 3.5 years | ​ | ​ | 3.5 years | ​ | ​ | 3.5 years
Weighted-average grant date fair value | ​ | $ | 1.22 | ​ | $ | 1.73 | ​ | $ | 1.90

​

During the year ended December 31, 2020, the Company recorded stock option expense of $0.6 million (2019 – $0.7 million, 2018 – $0.3 million) while the corresponding fair value of awards vesting in the period was $0.1 million (2019 – $0.4 million and 2018 – $0.7 million).

At December 31, 2020, there was $1.4 million (2019 – $1.0 million, 2018 - $0.4 million) of unrecognized compensation expense related to 6.1 million (2019 – 3.0 million, 2018 – 0.7 million) unvested stock options outstanding. This cost is expected to be recognized over a weighted-average period of approximately 1.6 years (2019 – 1.5 years, 2018 – 1.4 years).

The following table summarizes the status and activity of non-vested stock options for the year ended December 31, 2020, for the Company’s Plan and the replacement options from the acquisition of Lexam:

NOTE 15 NET LOSS PER SHARE

Basic net income (loss) per share is computed by dividing the net income or (loss) available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed similarly except that the weighted average number of common shares is increased to reflect all dilutive instruments. Diluted net income per share is calculated using the treasury stock method. In applying the treasury stock method, employee stock options with an exercise price greater than the average quoted market price of the common shares for the period outstanding are not included in the calculation of diluted net income per share as the impact is anti-dilutive. Potentially dilutive instruments are not considered in calculating the diluted loss per share, as their effect would be anti-dilutive.

Below is a reconciliation of the basic and diluted weighted average number of common shares and the computations for basic and diluted net (loss) per share for the years ended December 31, 2020, 2019 and 2018:

​

For the years ended December 31, 2020, 2019 and 2018, all outstanding options to purchase shares of common stock and share purchase warrants were excluded from the respective computations of diluted loss per share, as the Company was in a loss position, and all potentially dilutive instruments were anti-dilutive and therefore not included in the calculation of diluted net loss per share.

NOTE 17 FAIR VALUE ACCOUNTING

As required by accounting guidance, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

Assets and liabilities measured at fair value on a recurring basis

The following tables identify the Company’s assets and liabilities measured at fair value on a recurring basis (at least annually) by level within the fair value hierarchy as at December 31, 2020 and 2019, as reported in the Consolidated Balance Sheets:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Fair value as at December 31, 2020 |  | Fair value as at December 31, 2019
​ |  | Level 1 |  | Level 2 |  | Total |  | Level 1 |  | Level 2 |  | Total
Marketable equity securities | ​ | $ | — | ​ | $ | — | ​ | $ | — | ​ | $ | 1,885 | ​ | $ | — | ​ | $ | 1,885
Total investments | ​ | $ | — | ​ | $ | — | ​ | $ | — | ​ | $ | 1,885 | ​ | $ | — | ​ | $ | 1,885

​

The Company's investments as at December 31, 2019 mainly consist of marketable equity securities which are exchange-traded and are valued using quoted market prices in active markets and as such are classified within Level 1 of the fair value hierarchy. The fair value of the investments is calculated as the quoted market price of the marketable equity security multiplied by the quantity of shares held by the Company.

The fair value of other financial assets and liabilities were assumed to approximate their carrying values due to their short-term nature and historically negligible credit losses.

Debt is recorded at a carrying value of $48.2 million at December 31, 2020 (December 31, 2019 - $49.5 million) and approximates its fair value, given our recent refinancing.

Impairment of Mineral Property

During the year ended December 31, 2020, the Company recorded an impairment of long-lived assets at the Gold Bar Mine totaling $83.8 million based on Level 3 inputs. See Note 9 for details.

Reclamation Bonds

As part of its ongoing business and operations, the Company is required to provide bonding for its environmental reclamation obligations in the United States and Canada. These bonding obligations are satisfied by surety bonds, as discussed below. Pursuant to the requirements imposed by the United States Bureau of Land Management (“BLM”), the Company has Nevada obligations of $20.1 million which primarily pertains to the Tonkin and Gold Bar properties. Under Canadian regulations, the Company has bonding obligations of $11.7 million (C$15.0 million) with respect to the Fox Complex. Furthermore, under Canadian regulations, the Company was required to deposit approximately $0.1 million with respect to its Timmins properties acquired from Lexam; the $0.1 million is recorded as restricted cash (Note 19).

Surety Bonds

As at December 31, 2020, the Company has a surety facility in place to cover substantially all of its bonding obligations, which include $20.1 million of bonding in Nevada and $11.7 million (C$15.0 million) of bonding in Canada. The terms of the facility carry an annual financing fee of 2.3% and require a deposit of 12%. The surety bonds are available for draw down by the beneficiary in the event the Company does not perform its reclamation obligations. If the specific reclamation requirements are met, the beneficiary of the surety bonds will release the instrument to the issuing entity. The Company believes it is in compliance with all applicable bonding obligations and will be able to satisfy future bonding requirements, through existing or alternative means, as they arise. As at December 31, 2020, the Company held $3.6 million in restricted cash as deposit against the surety facility (Note 19).

Streaming Agreement

As part of the acquisition of the Fox Complex in 2017, the Company assumed a gold purchase agreement (streaming contract) related to production, if any, from certain claims. Under the streaming contract, the Company is obligated to sell 8% of gold production from the Black Fox mine and 6.3% from the adjoining Pike River property (Black Fox Extension) to Sandstorm Gold Ltd. at the lesser of market price or $561 per ounce (with inflation adjustments of up to 2% per year) until 2090.

The Company records revenue on these shipments based on the contract price at the time of delivery to the customer. During the year ended December 31, 2020, the Company recorded revenue of $1.2 million (2019 – $1.5 million) related to the gold stream sales.

Flow-through Eligible Expenses

As of December 31, 2020, the Company completed two rounds of flow-through share issuance’s (Note 14) closing on September 10, 2020 and December 31, 2020. As a result, the Company is committed to spend $18.3 million on CEE at its Timmins operations in Canada by the end of 2022. Through December 31, 2020, the Company has incurred $1.9 million in eligible expenses of required flow-through spend.

Other potential contingencies

The Company’s mining and exploration activities are subject to various laws and regulations governing the protection of the environment. These laws and regulations are continually changing and generally becoming more restrictive. The Company conducts its operations so as to protect public health and the environment, and believes its operations are materially in compliance with all applicable laws and regulations. The Company has made, and expects to make in the future, expenditures to comply with such laws and regulations.

The Company and its predecessors have transferred their interest in several mining properties to third parties throughout its history. The Company could remain potentially liable for environmental enforcement actions related to its prior

​

The Company reviews the measurement of its deferred tax assets at each balance sheet date. On the basis of available information at December 31, 2020, the Company has provided a valuation allowance for certain of its deferred assets where the Company believes it is more likely than not that some portion or all of such assets will not be realized. The change in valuation allowance of approximately $33.1 million primarily reflects the impact of losses during the year from impairments and operations.

The table below summarizes changes to the valuation allowance:

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
For the year ended December 31, |  | Balance at beginning of year |  | Additions(a) |  | Deductions(b) |  | Balance at end of year
2020 | ​ | $ | 121,212 | ​ | $ | 39,794 | ​ | $ | (6,708) | ​ | $ | 154,298
2019 | ​ | ​ | 124,153 | ​ | ​ | 2,104 | ​ | ​ | (5,045) | ​ | ​ | 121,212
2018 | ​ | ​ | 123,648 | ​ | ​ | 12,232 | ​ | ​ | (11,727) | ​ | ​ | 124,153

(a) | The additions to valuation allowance mainly result from the Company and its subsidiaries incurring losses and exploration expenses for tax purposes which do not meet the more-likely-than-not criterion for recognition of deferred tax assets.

(b) | The reductions to valuation allowance mainly result from release of valuation allowance, expiration of the Company’s tax attributes, foreign exchange reductions of tax attributes in Canada, Mexico and Argentina and inflationary adjustments to tax attributes in Argentina.
