NOTE 1 NATURE OF OPERATIONS AND BASIS OF PRESENTATION

McEwen Mining Inc. (the “Company”), through its predecessor entity, US Gold Corporation, was organized under the laws of the State of Colorado on July 24, 1979. The Company is engaged in the production and sale of gold and silver, as well as the development and exploration of copper, gold, and silver mineral properties across North and South America.

The Company owns a 100% interest in the Gold Bar mine in Nevada, United States, the Fox Complex in Ontario, Canada, the Fenix Project in Sinaloa, Mexico and a portfolio of exploration properties in the United States, Canada, Mexico and Argentina. As of September 30, 2024, the Company also owns a 48.3% interest in McEwen Copper Inc. (“McEwen Copper”), owner of the Los Azules copper project in San Juan, Argentina and a 49.0% 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. The Company reports its investments in McEwen Copper and MSC under the equity method of accounting.

The interim consolidated financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and are unaudited. While information and note disclosures normally included in annual financial statements and prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations, the Company believes that the information and disclosures included in the interim consolidated financial statements are adequate and not misleading. Therefore, these interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto and the summary of significant accounting policies included in the Company’s annual report on Form 10-K for the year ended December 31, 2023. Except as noted below, there have been no material changes in the footnotes from those accompanying the audited consolidated financial statements contained in the Company’s Form 10-K for the year ended December 31, 2023.

In management’s opinion, the unaudited Consolidated Statements of Operations and Comprehensive Loss (“Statement of Operations”) for the three and nine months ended September 30, 2024 and 2023, the unaudited Consolidated Balance Sheet as at September 30, 2024 and the Consolidated Balance Sheet as at December 31, 2023, the unaudited Consolidated Statement of Changes in Shareholders’ Equity for the three and nine months ended September 30, 2024 and 2023, and the unaudited Consolidated Statements of Cash Flows for the nine months ended September 30, 2024 and 2023, contained herein, reflect all adjustments, consisting solely of normal recurring items, which are necessary for the fair presentation of the Company’s financial position, results of operations and cash flows on a basis consistent with that of the Company’s prior audited consolidated financial statements. However, the results of operations for the interim periods may not be indicative of results to be expected for the full fiscal year. 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.

​

References to “CAD” refers to Canadian Dollar, “USD” refers to United States Dollar, and “MXN” refers to Mexican Peso.

​

NOTE 2 OPERATING SEGMENT REPORTING

​

The Company is a mining and minerals production, development, and exploration company focused on precious and base 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 the allocation of resources to these segments at the geographic region level, major mine/project level or investment level 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 for accounting purposes. The Company’s business activities that are not considered operating segments are included in the General and Administrative and Other income/expense line item in the below table and are provided for reconciliation purposes.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

September 30, 2024

​

NOTE 8 MINERAL PROPERTY INTERESTS AND PLANT AND EQUIPMENT

The applicable definition of proven and probable reserves is set forth in the Regulation S-K 1300 requirements of the SEC. 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 Mine and San José properties have proven and probable reserves estimated in accordance with S-K 1300. The Fox Complex is depleted and depreciated using the units-of-production method over estimated mineral resources, as the project does not have proven and probable reserves that conform to the guidance under S-K 1300.

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.

During the nine months ended September 30, 2024, no indicators of impairment were noted for any of the Company’s mineral property interests.

​

The income or loss from the investment in MSC attributable to the Company includes amortization of the fair value increments arising from the initial purchase price allocation and related income tax recovery. The income tax recovery reflects the impact of the devaluation of the Argentine peso against the U.S. dollar on the peso-denominated deferred tax liability recognized at the time of acquisition, as well as income tax rate changes over the periods.

​

Changes in the Company’s investment in MSC for the nine months ended September 30, 2024, and for the year ended December 31, 2023, are as follows:

On December 14, 2023, the Company issued 1,903,000 flow-through common shares for gross proceeds of $16.1 million. The issuance consisted of the CEE offering of 788,000 common shares priced at $9.27 per share and the CDE offering of 1,115,000 common shares priced at $7.86 per share. Total proceeds were allocated between the sale of tax benefits and the sale of common shares. Total issuance costs of $1.0 million were accounted for as a reduction to the value of common shares issued. Net proceeds of $15.1 million were allocated between the sale of tax benefits in the amount of $1.7 million and the sale of common shares in the amount of $13.4 million.

​

On June 14, 2024, the Company issued 1,533,000 flow-through common shares for gross proceeds of $21.8 million. The issuance consisted of the CEE offering of 643,000 common shares priced at $15.45 per share and the CDE offering of 890,000 common shares priced at $13.40 per share. Proceeds are expected to be used for the ongoing exploration and development of the Fox Complex. Total proceeds were allocated between the sale of tax benefits and the sale of common shares. Total issuance costs of $1.4 million were accounted for as a reduction in the value of the common shares. Net proceeds of $20.4 million were allocated between the sale of tax benefits in the amount of $6.0 million and sale of common shares in the amount of $14.4 million.

​

The Company is required to spend these flow-through share proceeds on flow-through eligible expenditures, as defined by subsection 66.1(5) and 66.1(6) of the Income Tax Act (Canada). As of September 30, 2024, the Company incurred a total of $6.9 million in eligible CEE and a total of $6.7 million in eligible CDE (December 31, 2023 - $nil).

Shares Issued in Timberline Acquisition

​

On August 19, 2024, the Company acquired Timberline Resource Corporation (“Timberline”). Pursuant to the Agreement and Plan of Merger, the Company issued 1,839,306 common shares with a fair value of $18.3 million and 205,349 warrants valued at $0.9 million. The fair value of instruments was included in the cost of acquired assets, as described in Note 17.

​

The number of common shares to be issued was determined by multiplying the number of Timberline shares outstanding by the exchange ratio of 0.01. The Company recorded $17.7 million in equity for the common shares issued, determined as total proceeds of $18.3 million less issuance costs of $0.6 million.

​

Outstanding Timberline warrants were assumed by the Company on the date of the acquisition. Each of the warrants assumed entitles the holder to purchase one share of the Company at the agreed-upon exercise price, as converted using the exchange ratio. Of the 205,349 warrants issued, 37,500 expired on October 15, 2024; 72,849 expire on August 31, 2026; and 95,000 expire on December 31, 2027. Exercise prices for each series are $12.00, $8.00, and $6.00, respectively.

NOTE 13 NET LOSS PER SHARE

Basic net loss per share is computed by dividing the net loss by the weighted average number of common shares outstanding during the period. For periods in which the Company has reported a net loss, diluted net loss per share is computed in the same manner as basic net loss per share, as instruments are generally anti-dilutive during such periods.

For the nine months ended September 30, 2024, all 848,480 outstanding stock options and all 2,375,275 outstanding warrants were excluded from the computation of diluted loss per share. Similarly, for the nine months ended September 30, 2023, all 971,504 outstanding stock options and all 2,976,816 outstanding warrants were excluded.

Assets and liabilities measured at fair value on a recurring basis

The following table identifies certain of the Company’s assets and liabilities measured at fair value on a recurring basis by level within the fair value hierarchy as at September 30, 2024 and December 31, 2023, as reported in the Consolidated Balance Sheets:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Fair value as at September 30, 2024 | Fair value as at December 31, 2023
​ |  | Level 1 |  | Level 2 |  | Total |  | Level 1 |  | Level 2 |  | Total
Marketable securities | ​ | $ | 1,001 | ​ | $ | — | ​ | $ | 1,001 | ​ | $ | 1,743 | ​ | $ | — | ​ | $ | 1,743

​

Marketable equity securities that the Company holds 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 investment is calculated as the quoted market price of the marketable equity security multiplied by the number of shares held by the Company.

The fair value of financial assets and liabilities held as at September 30, 2024 were assumed to approximate their carrying values due to their historically negligible credit losses.

Debt is recorded at a carrying value of $40.0 million (December 31, 2023 – $40.0 million). The debt is not traded on quoted markets and approximates its fair value based on recent refinancing.

​

NOTE 16 COMMITMENTS AND CONTINGENCIES

Reclamation obligations

As part of its ongoing business and operations, the Company is required to provide bonding for its environmental reclamation obligations. As at September 30, 2024, the Company had surety facilities in place to cover its bonding obligations, which include $32.3 million of bonding in Nevada and $7.4 million (C$10.0 million) of bonding in Canada.

The terms of the facilities carry an average annual financing fee of 2.3% and require a deposit of 6.1%. 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 September 30, 2024, the Company recorded $3.1 million in restricted cash in non-current assets as a deposit against the surety facility.

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 from certain land claims. The Company is obligated to sell 8% of gold production from the Black Fox mine (including the Froome deposit) 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. During nine months ended September 30, 2024, the realized gold price from the streaming agreement was $601 per ounce (nine months ended September 30, 2023 – $589 per ounce).

​

The Company records the revenue from these shipments based on the contract price at the time of delivery to the customer. During the three and nine months ended September 30, 2024, the Company recorded revenue of $0.4 million and $1.2 million, respectively (three and nine months ended September 30, 2023 –$0.5 million and $1.6 million, respectively) related to the gold stream sales.

Flow-through eligible expenses

On December 14, 2023, the Company completed a flow-through share issuance for gross proceeds of $16.1 million. The proceeds of this offering will be used for the continued exploration and development of the Company’s properties in the Timmins region of Canada. As at September 30, 2024, the Company has incurred $13.7 million in CEE and CDE and expects to fulfill its remaining obligations by the end of 2024.

On June 14, 2024, the Company completed a flow-through share issuance for gross proceeds of $21.9 million. The proceeds of this offering will be used for the continued exploration and development of the Company’s properties in the Timmins region of Canada. The Company expects to fulfill its CEE and CDE obligations from its most recent raise by the end of 2025.

​

Prepayment agreement

In May 2024, the Company extended the existing precious metals purchase agreement with Auramet International LLC (“Auramet”). Key terms of the agreement remained unchanged. Under this agreement, the Company may sell the gold on a Spot Basis, on a Forward Basis and on a Supplier Advance basis, i.e., the gold is priced and paid for while the gold is:

| (i) | at a mine for a maximum of 15 business days before shipment; or

| (ii) | in transit to a refinery; or

| (iii) | while being refined at a refinery.

​

During the three and nine months ended September 30, 2024, the Company received net proceeds of $nil and $4.8 million, respectively, from the sales on a Supplier Advance Basis (three and nine months ended September 30, 2023 –$41.2 million and $93.4 million, respectively). During the nine months ended September 30, 2024, the Company recorded revenue of $4.8 million related to gold sales (nine months ended September 30, 2023 – $83.2 million) with no amounts outstanding under this facility as at September 30, 2024.

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 ownership of such properties. However, the Company has no reasonable belief that any violation of relevant environmental laws or regulations has occurred regarding these transferred properties.

​

NOTE 17 TIMBERLINE ACQUISITION

​

On August 19, 2024, the Company completed the acquisition of Timberline. The acquisition of Timberline expands the Company’s existing portfolio of exploration-stage Mineral Property Interests in Nevada.

​

The Company accounted for the acquisition of Timberline as an asset acquisition, according to ASC 805 – Business Combinations.

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

​

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

​

The discussion also analyzes our results of operations for the three and nine months ended September 30, 2024 and compares those to the results for the three and nine months ended September 30, 2023. Regarding properties or projects that are not in production, we provide some details of our plan of operation. We suggest that you read this discussion in conjunction with MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS and our audited consolidated financial statements contained in our annual report on Form 10-K for the year ended December 31, 2023.

​

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 costs, cash costs per ounce, all-in sustaining costs (“AISC”), all-in sustaining cost per ounce, adjusted earnings before interest, taxes, depreciation, and amortization (“Adjusted EBITDA”), and average realized price per ounce. 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.

For a reconciliation of these non-GAAP measures to the amounts included in our Consolidated Statements of Operations and Comprehensive Loss for the three and nine months ended September 30, 2024, and 2023 and to our Consolidated Balance Sheets as of September 30, 2024, and December 31, 2023, and certain limitations inherent in such measures, please see the discussion under “Non-GAAP Financial Performance Measures,” beginning on page 33.

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 measured, indicated, and inferred resources 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 ever will have proven or probable reserves at those properties as defined by S-K 1300.

​

Throughout this Management’s Discussion and Analysis (“MDA”), the reporting periods for the three months ended September 30, 2024, and 2023 are abbreviated as Q3/24 and Q3/23, respectively, and the reporting periods for the nine months ended September 30, 2024, and 2023 are abbreviated as 9M/24 and 9M/23, respectively.

​

Disclosed gold equivalent ounces (“GEO”) includes gold and silver ounces calculated based on a gold to silver ratio of 85:1 for Q3/24 and 82:1 for Q3/23, and 85:1 for 9M/24 and 83:1 for 9M/23, which is based on the average per ounce price of gold and silver during each period.

​

Q3/24 OPERATING AND FINANCIAL HIGHLIGHTS

​

Highlights for Q3/2024 are summarized below and discussed further under “Consolidated Performance”:

​

Corporate Developments

​

| ● | On July 12, 2024, McEwen Copper closed an initial tranche of a private placement financing for up to $70.0 million to advance the Los Azules copper project to feasibility, consisting of an investment by McEwen Mining for $14.0 million, and by Rob McEwen, Chairman and Chief Owner, for $5.0 million. McEwen Copper issued 466,667 common shares to McEwen Mining for the aforementioned proceeds. As of September 30, 2024, the Company owned a 48.3% interest in McEwen Copper. Subsequent to quarter end, McEwen Copper closed a second tranche of the offering for $37.0M, including $35.0M from Nuton LLC, a Rio Tinto Venture, and the Company’s ownership interest in McEwen Copper decreased from 48.3% to 46.4%.

​

| ● | On August 19, 2024, the Company successfully completed its acquisition of all of the issued and outstanding shares of Timberline Resources Corporation (“Timberline”) by way of a merger between Timberline and a wholly owned subsidiary of the Company. As a result, the shares of Timberline ceased trading and were delisted from the TSX Venture Exchange and the OTCQB. This transaction augments McEwen’s existing portfolio of development and exploration projects in Nevada, including properties adjacent to our existing Gold Bar mine with near-term development potential.

​

Operational Highlights

​

| ● | Consolidated production of 35,180 GEOs in Q3/24 decreased by 9% compared to 38,613 GEOs in Q3/23. During 9M/24, we produced 103,445 GEOs, including 41,290 attributable GEOs from the San José mine(1), and reiterate our consolidated production guidance of 130,000 to 145,000 GEOs for full year 2024, supported by the production performance from the Gold Bar mine.

​

| ● | Consolidated sales of 34,435 GEOs in Q3/24 decreased by 2% compared to 35,244 GEOs in Q3/23. During 9M/24, we sold 104,025 GEOs, including 42,241 attributable GEOs from the San José mine(1) compared to 100,859 GEOs sold during 9M/23 including 42,879 attributable GEOs from the San José mine(1).

​

| ● | At the Fox Complex, we produced 7,855 GEOs during Q3/24, a 30% decrease compared to 11,174 GEOs produced during Q3/23. Production continued to be impacted by a shortfall in development meters in H1/24 due to a stope failure, limiting stope availability in Q3/24. During 9M/24, we produced 23,600 GEOs compared with 34,225 GEOs during 9M/23. While stope availability is expected to improve during Q4/24, resulting in higher GEO production compared to prior quarters in 2024, we expect full year production to be approximately 15% to 20% below our annual production guidance of 40,000 to 42,000 GEOs.

​

| ● | At the Gold Bar Mine, we produced 13,640 GEOs during Q3/24, an increase of 43% compared to 9,507 GEOs produced in Q3/23. Despite a 49% decrease in stacked tonnes, higher mined grades and recovery rates compared to prior year improved production significantly. During 9M/24, we produced 37,654 GEOs at the Gold Bar mine, and expect to meet, and potentially exceed, annual production guidance of 40,000 to 43,000 GEOs.

​

| ● | At the San José Mine, Q3/24 production of 13,684 GEOs decreased by 24% compared to 17,932 GEOs during Q3/23. Production was impacted by lower than expected mined metal grades, however with additional infill drilling performed during the quarter and availability of new mining areas, grade performance is expected to improve during Q4/24. With 41,290 attributable GEOs produced in 9M/24, we expect the San José mine to meet annual production guidance of 50,000 to 60,000 attributable GEOs(1).

​

| ● | We continued to advance our Los Azules copper project to feasibility. While drilling ceased during Argentina’s winter season, the McEwen Copper team remains on track to deliver a feasibility study during the first half of 2025.

​

22

Table of Contents

| ● | We continued to meet safety expectations at our 100% owned operating mines. During 9M/24, we did not have any lost-time incidents at our Fox Complex and Gold Bar Mine. Both of our operating mines have operated without lost-time incidents for over four years.

​

Financial Highlights

​

| ● | We reported consolidated cash and cash equivalents of $29.2 million, and consolidated working capital of $8.6 million as at September 30, 2024. (December 31, 2023 – $23.0 million and $22.7 million, respectively).

​

| ● | Revenue of $52.3 million was reported in Q3/24 from the sale of 21,350 GEOs from our 100% owned operations at an average realized price(2) of $2,499 per GEO. This compares to Q3/23 revenue of $38.4 million from the sale of 20,620 GEOs from our 100% owned operations at a realized price of $1,920 per GEO.

​

| ● | We reported gross profit of $13.8 million in Q3/24, compared to $3.8 million in Q3/23 from our 100% owned operations. Our increase in revenue that contributed to the increase in gross profit in Q3/24 was slightly offset by higher production costs attributable to sales during the 2024 period.

​

| ● | Net loss for Q3/24 was $2.1 million, or $0.04 per share, compared to a net loss of $18.5 million for Q3/23, or $0.39 per share. Our results improved primarily due to lower attributable advanced projects expenditures at Los Azules, as well as our higher gross profit described above.

​

| ● | Adjusted EBITDA(2) for Q3/24 was $10.5 million, or $0.20 per share, compared to Q3/23 adjusted EBITDA of $1.5 million, or $0.03 per share. Adjusted EBITDA excludes the impact of McEwen Copper’s results and reflects the earnings of our operating properties, including the San José mine.

​

| ● | Fox Complex unit costs: Cash costs(2) and AISC(2) per GEO sold in Q3/24 were $1,572 and $1,953, respectively. 9M/24 cash costs and AISC per GEO sold were $1,572 and $1,909, respectively, as compared to annual guidance ranges of $1,225 to $1,325 and $1,450 to $1,550, respectively. Accelerated development costs to improve stope availability for Q4/24 increased unit costs during the third quarter. While we expect production to improve in the fourth quarter, including adding on new production from our Black Fox mine, we expect that unit costs will be 15% to 20% higher than annual guidance.

​

| ● | Gold Bar unit costs: Cash costs(2) and AISC(2) per GEO sold in Q3/24 were $1,281 and $1,822, respectively. 9M/24 cash costs and AISC per GEO sold were $1,302 and $1,548, respectively, as compared to annual guidance of $1,450 to $1,550 and $1,650 to $1,750, respectively. While higher planned stripping costs in Q3/24 increased unit costs, we remain on track to meet our full year cost guidance.

​

| ● | San José unit costs: Cash costs(2) and AISC(2) per GEO sold in Q3/24 were $2,173 and $2,675, respectively. 9M/24 cash costs and AISC per GEO sold were $1,788 and $2,194, respectively, as compared to full year guidance of $1,300 to $1,500 and $1,500 to $1,700, respectively. While Argentine cost inflation remained high, the relative strength of the peso against the US Dollar continued to increase costs in US Dollar terms. Combined with lower than expected mined grades, unit costs were higher than expected. While production is expected to recover in Q4/24 from new mining areas, unit costs are expected to remain above guidance due to macroeconomic factors.

​

Exploration and Mineral Resources and Reserves

​

| ● | McEwen Copper invested $6.1 million at the Los Azules copper project in Argentina during Q3/24 to advance its feasibility study and associated activities. Including amounts spent by Minera Andes Inc. prior to 2012, and McEwen Mining prior to 2021, we have invested over $350 million in exploration expenditures to develop Los Azules as a world-class copper deposit.

​

| ● | We incurred $1.8 million in exploration expenses at Fox Complex during Q3/24 to advance our Grey Fox project, where we completed 29,918 feet (9,119 meters) of drilling and initiated mineralogical studies to better understand the nature of the mineralization.

​

| ● | We incurred $3.5 million in exploration expenses at the Gold Bar mine on near-term production targets during Q3/24, including the Cabin, Gold Bar South and Hunter deposits, as well as greenfield targets for mine life extension opportunities.

​

CONSOLIDATED PERFORMANCE

​

Driven by a 36% increase in revenue from $38.4 million in Q3/23 up to $52.3 million in Q3/24, and slightly offset by a 12% increase in production costs, we reported a gross profit of $13.8 million in Q3/24, compared to a gross profit of $3.8 million for Q3/23.

​

Supported by our improvement in gross profit described above, we reported a net loss of $2.1 million (or $0.04 per share) and adjusted EBITDA of $10.5 million (or $0.20 per share) in Q3/24, compared to a net loss of $18.5 million (or $0.39 per share) and adjusted EBITDA of $1.5 million (or $0.03 per share) in Q3/23.

​

Production from our 100% owned mines of 21,495 GEOs in Q3/24 increased by 814 GEOs, from 20,681 GEOs produced in Q3/23. At the Gold Bar mine, the production increase of 4,133 GEOs in Q3/24 compared to Q3/23 was attributable to a 21% increase in higher gold grades of stacked mineralized material, and higher heap leach recovery rates. At the Fox Complex, the production decrease of 3,319 GEOs in Q3/24 compared to Q3/23 was driven by a 9% decrease in tonnes processed and a 21% decrease in average head grades processed.

​

Our attributable share of San José mine production was 13,684 GEOs in Q3/24, or 24% lower than the 17,932 GEOs produced in Q3/23. The decrease was primarily driven by temporary lower than expected metal grades mined and processed.

​

CONSOLIDATED OPERATIONS REVIEW

​

Revenue from gold and silver sales from 100% owned operations increased to $52.3 million in Q3/24, compared to $38.4 million in Q3/23 due to higher average realized gold prices and consolidated gold sales, as described above. Our average realized gold price in Q3/24 was $2,499 per GEO, compared to $1,920 per GEO in Q3/23.

​

Production costs applicable to sales increased to $29.7 million in Q3/24, compared to $26.5 million in Q3/23. Production costs increased primarily at Gold Bar compared to prior year, driven by higher mining rates and contractor unit costs.

​

25

Table of Contents

Advanced project costs were $2.5 million in Q3/24, compared to $20.4 million in Q3/23. Advanced project costs primarily relate to the Fenix Project in both Q3/23 and Q3/24, and Los Azules in Q3/23. Following the deconsolidation of McEwen Copper in Q4/23, the Company’s attributable costs for Los Azules are recognized through the Loss from investment in McEwen Copper line item on our Statement of Operations and are no longer recognized within Advanced Project Costs.

​

Exploration costs were $5.3 million in Q3/24, compared to $4.7 million in Q3/23. Exploration expenditures focused on the Grey Fox project at the Fox Complex, and on near-term production targets and mine life extension opportunities at Gold Bar.

​

Loss from investment in MSC: During Q3/24 we recorded a loss of $1.2 million, compared to a loss of $2.7 million in Q3/23. Details of MSC’s operating results are presented in the “Operations Review” section of this MDA and Note 9 to the Consolidated Financial Statements.

​

Loss from investment in McEwen Copper: During Q3/24 we recorded a loss of $1.9 million representing our attributable portion of the costs of McEwen Copper to advance the Los Azules project to feasibility. Prior to Q4/23, the financial results of McEwen Copper were consolidated. Details of McEwen Copper’s operating results are presented in the “Operations Review” section of this MDA and Note 9 to the Consolidated Financial Statements.

​

Interest and other finance expense, net was $1.1 million in Q3/24, a $11.4 million decrease compared to income of $10.3 million in Q3/23. During Q3/23, interest and other finance income was impacted by the consolidation of McEwen Copper’s financial results, which included income earned from its investments of cash reserves not immediately required for exploration activities.

​

Other expense was $0.1 million in Q3/24, compared to an expense of $10.1 million in Q3/23. The increase was primarily attributable to a decrease in foreign exchange losses following the deconsolidation of McEwen Copper, as a sizable portion of its treasury was held in Argentine pesos during Q3/23.

​

Income and mining tax expense was $0.8 million in Q3/24, compared to a recovery of $0.2 million in Q3/23. The decrease was primarily due to the Nevada net proceeds tax, partially offset by adjustments in temporary tax differences related to our McEwen Copper investment and the amortization of the flow-through share premium.

​

LIQUIDITY AND CAPITAL RESOURCES

​

Our cash, cash equivalents and restricted cash balance increased by $4.8 million during 2024, from $27.5 million as at December 31, 2023 to $32.3 million as at September 30, 2024.

​

Cash from operating activities of $30.7 million during 9M/24 reflects the net loss of $35.5 million for the period, adjusted for non-cash impacts, including net losses from equity method investments of $31.9 million, depreciation, amortization, and depletion of $24.0 million, income and mining tax recovery of $6.3 million, an increase in non-cash working capital of $12.5 million, stock-based compensation of $2.1 million, and reclamation accretion and adjustments to estimate of $1.1 million. Further details are provided in the Consolidated Statements of Cash Flows.

​

Cash used in investing activities of $45.1 million during 9M/24 consisted of additions to mineral property interests and plant and equipment of $30.3 million, driven primarily by capital development at the Fox Complex, and the investment of an additional $14.0 million in McEwen Copper during the 2024 period, notes receivable acquired of $1.9 million. This was slightly offset by $1.1 million of cash and restricted cash received from the acquisition of Timberline.

​

Cash provided by financing activities of $19.5 million during 9M/24 consisted of proceeds from the issuance of flow-through common shares of $20.4 million in June 2024, offset by finance lease payments of $0.9 million.

​

​

26

Table of Contents

Working capital as at September 30, 2024 was $8.6 million, and decreased by 62% from $22.7 million as at December 31, 2023. The decrease in working capital was driven by the reclassification of $9.0 million of long-term debt to current liabilities, an increase in accounts payables and accrued liabilities of $6.2 million, a $4.7 million increase in flow-through share premium liabilities, offset by a $6.2 million increase in cash and cash equivalents described above, and a $0.7 million increase in other current assets.

The Company believes that it has sufficient liquidity along with funds generated from ongoing operations to fund anticipated cash requirements for operations, capital expenditures and working capital purposes for the next 12 months.

Q3/24 compared to Q3/23

​

The Gold Bar mine produced 13,640 GEOs in Q3/24, representing a 43% increase from 9,507 GEOs produced in Q3/23. The increase in quarterly production was a result of higher average gold grades in stacked material of 0.84 g/t Au in Q3/24 compared to 0.69 g/t Au in Q3/23, as well as higher recoveries realized during Q3/24 from previously stacked material.

​

Revenue from gold and silver sales increased 85% to $33.3 million in Q3/24, compared to $18.0 million in Q3/23. The increase in revenue was the result of higher GEOs sold during Q3/24 of 13,333 GEOs in Q3/24 compared to 9,420 GEOs in Q3/23 along with a higher average realized gold price of $2,499 per GEO in Q3/24 compared with $1,920 per GEO in Q3/23.

Production costs applicable to sales increased 19% to $17.1 million in Q3/24 from $14.4 million in Q3/23. Higher mining rates, including for stripping, and contractor unit costs contributed to the increase in year-over-year costs.

​

Cash costs and AISC per GEO sold in Q3/24 were $1,281 and $1,822 respectively, compared to $1,529 and $2,160 in Q3/23, respectively. Unit costs generally improved due to the higher GEOs sold in Q3/24 relative to Q3/23, offset by higher mining costs, including for capital development.

​

Exploration Activities

At the Gold Bar mine, exploration activities focused on near-mine mine life extension opportunities at Cabin Creek, Gold Bar South and Hunter.

​

In Q3/24, exploration at the Cabin Creek pit included drilling and updating of the resource model to evaluate the economic feasibility of mining shallow oxide resources in 2025. Assays from this drilling returned 90 feet of oxidized gold mineralization grading 0.63 g/t, starting at a depth of 105 feet. Additional holes were drilled late in the quarter, to fill in data gaps in the model and extend open mineralization. Drilling is expected to continue into Q4/24.

At Gold Bar South, results from the North Zone drilling confirmed expansion of the near-surface gold resource. In the East Deep Zone, additional holes drilled during Q3/24 extended higher-grade oxidized gold mineralization along ENE-trending structural zones. This deeper mineralization remains open to the east and plans are being made for additional drilling.

At the Hunter exploration target, additional core drilling completed in Q3/24 defined the outer edges of the deposit and provided data to construct a geologic model in preparation for resource modelling. Development of the Hunter target is expected to result in production for 2026 onwards.

T imberline Acquisition

During August 2024, we closed the acquisition of Timberline Resources Corporation, which holds several exploration projects in Nevada, USA, two of which are located near current operations at the Gold Bar mine and have medium-term development potential. An initial phase of exploration is expected to begin at the historic Windfall project during Q4/24.

​

Q3/24 compared to Q3/23

​

The Fox Complex produced 7,855 GEOs from the Froome mine in Q3/24, which represented a 30% decrease from the 11,174 GEOs produced in Q3/23. Mine production was affected by a shortfall in development meters in H1/24 due to a stope failure, limiting stope availability in Q3/24 and negatively impacting planned mined and milled gold grades. Additional development was completed during Q3/24 to accelerate stope availability in Q4/24, including at our historic Black Fox underground mine.

​

Revenue from gold sales was $19.0 million in Q3/24, a decrease of $1.3 million compared to $20.3 million in Q3/23, A 28% decrease in GEOs sold was largely offset by an increase in the average realized gold price from $1,920 per GEO in Q3/23 to $2,499 per GEO in Q3/24. Realized gold prices at the Fox Complex are impacted by historic streaming arrangements, which require the sale of a portion of gold produced from the Froome and Black Fox mines at $601 per ounce as of Q3/24.

​

Production costs applicable to sales were $12.6 million, which increased in Q3/24 by $0.5 million from $12.1 million in Q3/23, driven primarily by higher mining contractor and labor costs required to complete work at Black Fox.

​

Table of Contents

Cash costs and AISC per GEO sold were $1,572 and $1,953 in Q3/24, respectively, compared to $1,572 and $1,909 in Q3/23, respectively. The increase in unit costs was driven primarily by lower GEOs sold as described above, as well as accelerated capital development costs to increase stope availability in respect of AISC.

​

Exploration Activities

​

During Q3/24, $1.8 million was incurred primarily for exploration at the Grey Fox property. This included 29,918 feet (9,119 meters) of drilling at Grey Fox as well as the initiation of a mineralogical study, including laser-induced breakdown spectroscopy, of lithologies at the Gibson and Whiskey Jack zones at Grey Fox to better understand the nature of the mineralization. An infill geophysics program will be conducted at Grey Fox in Q4/24 to check for Black Fox-style mineralization believed to be below Grey Fox.

​

Stock Developmen t Activities

​

During 9M/24, we invested $5.5 million in developing our Stock project. Earthworks have been completed in preparation for our mine portal construction later in 2024, with the objective of driving a ramp from the Stock East to the Stock West zones. We are also reviewing engineering plans for rehabilitation of the historic Stock shaft in 2025 to provide alternative means of access to the Stock ore bodies.

​

Mexico Segment

​

The Mexico segment includes the El Gallo mine and the related advanced-stage Fenix Project, located in Sinaloa state.

​

Advanced-Stage Properties – Fenix Project

​

On December 31, 2020, we announced the results of a feasibility study for the development of our 100%-owned Fenix Project, which includes existing heap leach material at the El Gallo mine and the El Gallo Silver deposit. Key environmental permits for Phase 1 were received in 2019, including the approval for an in-pit tailings storage facility and process plant construction. We are currently awaiting the renewal of key mining permits prior to a construction decision.

The processing plant is expected to employ proven and conventional mineral processing and precious metal recovery technologies. Phase 1 is projected to have a processing rate of 3,400 tons per day.

Tailings generated during operations are expected to be stored in the depleted Samaniego pit at the El Gallo site. This approach provides increased safety by avoiding the construction of embankment structures, focusing solely on the geochemical stability of the dam, rather than its physical stability.

​

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

​

Q3/24 compared to Q3/2023

​

On a 100% basis, the San José mine produced 27,927 GEOs in Q3/24, compared to 36,597 in Q3/23. The decrease in GEOs produced was driven by a 24% and 16% decrease in gold and silver head grades processed, respectively.

​

Revenue from gold and silver sales was $70.4 million in Q3/24, compared to $64.5 million in Q3/23. The increase was driven by a higher average realized gold price per ounce of $2,639/oz gold in Q3/24 compared with $2,138/oz gold in Q3/23, and offset by an 11% decrease in GEOs sold.

​

31

Table of Contents

Production costs applicable to sales were $58.0 million during Q3/24, compared to $43.4 million during Q3/23. While cost inflation remained high from an Argentine perspective, the relative strength of the peso against the US Dollar continued to increase costs in US Dollar terms.

​

Cash costs and AISC per GEO sold were $2,173 and $2,675 in Q3/24, respectively, compared to $1,445 and $1,953 in Q3/23, respectively. Negative foreign exchange impacts, combined with temporary lower than expected mined grades, resulted in higher than expected unit costs.

​

Investment in MSC

​

Our 49% attributable share of operations from our investment in MSC in Q3/24 resulted in a loss of $1.2 million, compared to a loss of $2.7 million in Q3/23. Despite higher than planned unit costs, the metals price environment has allowed the operation to strengthen its liquidity, improving its working capital balance to $75.5 million as at September 30, 2024, while also investing $8.5 million in exploration expenditures and $3.5 million in mill expansion costs during 2024.

​

​

McEwen Copper Inc.

​

As of September 30, 2024, we own a 48.3% interest in McEwen Copper, which owns a 100% interest in the Los Azules copper project in San Juan, Argentina, and the Elder Creek exploration project in Nevada, USA. Including amounts spent by Minera Andes Inc. prior to 2012, and directly by McEwen Mining prior to 2021, we have invested over $350 million in exploration expenditures to develop Los Azules as a world-class copper deposit.

​

Los Azules, San Juan, Argentina

​

The Los Azules project is one of the world’s largest undeveloped copper deposits and is located in the Province of San Juan, Argentina.

​

During the nine months ended September 30, 2024, Los Azules spent $91.9 million in exploration expenditures at the Los Azules copper project in Argentina. These funds primarily supported key activities required to complete our planned feasibility study, such as an extensive drilling program completed in June 2025, and the completion of geological and hydrological models. Our feasibility study is expected to be published towards during the first half of 2025.

​

2023-2024 Assay Results

​

At Los Azules, infill drilling has upgraded resource classifications, validated the geological model, and confirmed the high-grade zone. During the 2023-24 drilling season, over 70,000 meters (m) were completed, enhancing the interpretation of the geological model and extending mineralization of the supergene enrichment zone both at its edges and at depth.

Environmental Impact Assessment

​

The first presentation of the Environmental Impact Assessment to the Technical Evaluation Commission (“CIEAM”) was delivered on November 24, 2023. Comments raised by CIEAM primarily focused on water management and the preservation of onsite meadows/wetlands. Furthermore, additional works and infrastructure needs identified by the Company were addressed during the meeting. Following this presentation, in April 2024, CIEAM visited our Los Azules site for two days to continue their evaluation of our Environmental Impact Assessment.

​

Energy Supply Contract

​

McEwen Copper Inc. has reached an agreement with YPF Luz to power its Los Azules copper project in San Juan, Argentina, with renewable energy. The companies signed a Memorandum of Understanding to negotiate the energy supply, which will come from YPF Luz’s renewable assets connected to the Argentine Interconnection System. YPF Luz will also develop, construct, and finance a high-voltage transmission line to connect the project to the grid, ensuring a sustainable energy supply for the copper project.

​

Regime of Incentives for Investment (RIGI)

​

The Regime of Incentives for Investment aims to attract domestic and foreign investment to a number of sectors in Argentina, including mining, enhancing resource exploration and production while creating job opportunities and increasing energy security. The regime offers various benefits to companies, including reduced income tax rates, stability agreements for a predictable regulatory environment, and legal protections for investments. Additionally, RIGI facilitates access to mineral and energy resources providing clearer regulatory guidelines, and ensuring that companies can secure the necessary permits and licenses to operate, and provides a stable framework that reduces investment risks.

​

The fiscal and financial tax benefits associated with the RIGI are expected to lead to a significant enhancement of the overall economics of the Los Azules project, positively impacting both its net present value and internal rate of return.

​

NON-GAAP FINANCIAL PERFORMANCE MEASURES

​

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 use these measures to evaluate our business on an ongoing basis and believe that, in addition to conventional measures prepared in accordance with GAAP, certain investors use such non-GAAP measures to evaluate our 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 our 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 US 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 9, Equity Investments. The amounts in the reconciliation 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

33

Table of Contents

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 mine, 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 represent our legal claim to the assets and liabilities, or the revenues and expenses; and

​

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

​

Cash Costs and All-In Sustaining Costs

​

The terms cash costs, cash cost per ounce, all-in sustaining costs (“AISC”), 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 used by the mining industry 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. The 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 the 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 disposals, impairment charges and any items that are deducted for the purpose of normalizing items.

Adjusted EBITDA and adjusted EBITDA per share

​

Adjusted earnings before interest, taxes, depreciation, and amortization (“Adjusted EBITDA”) is a non-GAAP financial measure and does not have any standardized meaning. We use adjusted EBITDA to evaluate our operating performance and ability to generate cash flow from our wholly owned operations in production; we disclose this metric as we believe this measure provides valuable assistance to investors and analysts in evaluating our ability to finance our precious metal operations and capital activities separately from our copper exploration operations. The most directly comparable measure prepared in accordance with GAAP is net loss before income and mining taxes. Adjusted EBITDA is calculated by adding back McEwen Copper's income or loss impacts on our consolidated income or loss before income and mining taxes.

​

The following tables present a reconciliation of adjusted EBITDA:

Average realized price

​

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 the market (London P.M. Fix). The average realized price for our 100% owned properties 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 the average realized prices 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.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

​

Critical accounting policies and estimates used to prepare our financial statements are discussed with our Audit Committee as they are implemented on an annual basis.

​

The were no significant changes in our critical accounting policies or estimates since December 31, 2023. For further details on the Company’s accounting policies and estimates, refer to the Form 10-K for the year ended December 31, 2023.

​

FORWARD-LOOKING STATEMENTS

​

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, costs and feasibility of production, production estimates, receipt of permits or other regulatory or governmental approvals and plans for the development of our properties;

| ● | statements regarding strategic alternatives that we are, or may in the future, evaluate in connection with our business;

| ● | 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;

| ● | the anticipated timeframe for remediating the material weakness in our internal control over financial reporting and effectiveness of our disclosure controls and procedures; and

| ● | 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 the negative of these terms or similar expressions used in this report or incorporated by reference in this report, but the absence of these terms does not mean that a statement is not forward-looking.

​

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 that 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 Fox Complex).

| ● | expected tonnes moved and strip ratios.

| ● | available stockpile material (grades, tonnes, and accessibility).

| ● | estimates of in process inventory (either on the leach pad or plant for the El Gallo mine and Gold Bar, or in the mill facility for the San José mine and the Black Fox mine).

| ● | estimated leach recovery rates and leach cycle times (the El Gallo mine and Gold Bar).

| ● | estimated mill recovery rates (San José mine and Fox Complex).

| ● | dilution of material processed.

| ● | internal and contractor equipment and labor availability.

| ● | seasonal weather patterns.

38

Table of Contents

Actual production results are sensitive to variances in any of the key factors and assumptions noted above. As a result, we frequently evaluate and reconcile actual results to budgeted results to determine if key assumptions and estimates require modification. Any changes will, in turn, influence production guidance.

We caution you not to put undue reliance on these forward-looking statements, which speak only as of the date of this report. Further, the forward-looking information contained in this document or incorporated herein by reference is a statement of our present intention and is based on present facts and assumptions, and may change at any time and without notice, based on changes in such facts or assumptions. Readers should not place undue reliance on forward-looking statements.

​

RISK FACTORS IMPACTING FORWARD-LOOKING STATEMENTS

​

Important factors that could prevent us from achieving our stated goals and objectives include, but are not limited to, those set forth in the “Risk Factors” section in our report on Form 10-K for the year ended December 31, 2023 and other reports filed with the SEC, and the following:

​

| ● | our ability to raise funds required for the execution of our business strategy.

| ● | our acquisitions may not achieve their intended results. Our ability to secure permits or other regulatory and government approvals needed to operate, develop or explore our mineral properties and projects.

| ● | our ability to maintain an ongoing listing of our common stock on the New York Stock Exchange or another national securities exchange in the United States.

| ● | decisions of foreign countries, banks, and courts within those countries.

| ● | national and international geopolitical events and conflicts, and unexpected changes in business, economic, and political conditions.

| ● | operating results of MSC and McEwen Copper.

| ● | fluctuations in interest rates, inflation rates, currency exchange rates, or commodity prices.

| ● | timing and amount of mine production.

| ● | our ability to retain and attract key personnel.

| ● | technological changes in the mining industry.

| ● | changes in operating, exploration, or overhead costs.

| ● | access and availability of materials, equipment, supplies, labor and supervision, power, and water.

| ● | results of current and future exploration activities.

| ● | results of pending and future feasibility studies or the expansion or commencement of mining operations without feasibility studies having been completed.

| ● | changes in our business strategy.

| ● | interpretation of drill hole results and the geology, grade, and continuity of mineralization.

| ● | the uncertainty of reserve estimates and timing of development expenditures.

| ● | litigation or regulatory investigations and procedures affecting us.

| ● | changes in federal, state, provincial and local laws, and regulations.

| ● | local and community impacts and issues including criminal activity and violent crimes.

| ● | accidents, public health issues, and labor disputes.

| ● | uncertainty relating to title to mineral properties.

| ● | changes in relationships with the local communities in the areas in which we operate; and

| ● | decisions by third parties over which we have no control.

​

We undertake no responsibility or obligation to update publicly these forward-looking statements, except as required by law and may update these statements in the future in written or oral statements. Investors should take note of any future statements made by or on our behalf.

Item 3. 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, interest rate 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 49.0% interest held at MSC and our 48.3% ownership in McEwen Copper as of September 30, 2024, creates additional risks because, among other things, we do not exercise decision-making power over the day-to-day activities at MSC or McEwen Copper; however, implications from our partner’s decisions may result in us having to provide additional funding to MSC or McEwen Copper, or result in a further decrease in our percentage of ownership.

​

Foreign Currency Risk

​

The Company is exposed to foreign currency risks directly through exposure to the Mexican peso and Canadian dollar, and indirectly through exposure to the Argentine peso through our investments in MSC and McEwen Copper.

​

During the three months ended September 30, 2024, the Mexican peso depreciated 7% against the U.S dollar, compared to an 1.5% depreciation in the same period of 2023.

​

The Canadian dollar experienced a 1.2% appreciation against the U.S. dollar for the three months ended September 30, 2024, compared to a 2.1% depreciation in the comparable period of 2023.

​

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 hold portions of our cash reserves in non-U.S. dollar currencies.

​

Our Canadian dollar and Mexican peso cash balances were $6.8 million (CAD 9.2 million) and $0.5 million (MXN 9.8 million), respectively, as at September 30, 2024. The effect that a 1.0% change in these respective currencies would result in gains/losses that are immaterial for disclosure. We have not utilized material market risk-sensitive instruments to manage our exposure to the Canadian dollar and Mexican peso exchange rates but may do so in the future.

​

Equity Price Risk

​

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.

​

We have in the past sought and will likely in the future seek to acquire additional funding from the sale of common stock or other equity securities. Movements in the price of our investments 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.

40

Table of Contents

Commodity Price Risk

​

We produce and sell gold and silver. Changes in the market price of gold and silver have and will in the future significantly affect the results of our operations and cash flows. Changes in the price of gold and silver could materially affect our revenues. Based on our revenues from gold and silver sales of $52.3 million for the three months ended September 30, 2024, a 10% change in the price of gold and silver would have had an impact of approximately $5.2 million on our revenues. Changes in the price of gold and silver can also affect the provisionally priced sales that we make under sales agreements. At September 30, 2024, we had no gold or silver sales subject to provisional pricing at our 100% owned operations.

​

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 will 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 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 the financial condition of our counterparties, we do not anticipate that any of our customers will default on their obligations. As of September 30, 2024, we do not believe we have any significant credit exposure associated with precious metals and our doré sales agreements.

​

In Nevada and Ontario, Canada we are required to provide security to cover our projected reclamation costs. As at September 30, 2024, we have surety bonds of $44.8 million in place to satisfy bonding requirements for this purpose. The bonds have an annual fee of 2.3% of their value and require a deposit of 6.1% of the amount of the bond. Although we do not believe we have any significant credit exposure associated with these bonds or the deposit, we are exposed to the risk that the surety may default in returning our deposit 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.

​

Interest rate risk

​

Our outstanding debt consists of various equipment leases and the $40.0 million debt payable under the Third Amended and Restated Credit Agreement. As the debt is at fixed rates, we consider our interest rate risk exposure to be insignificant at this time.

Item 4. CONTROLS AND PROCEDURE S

​

Overview

​

We are in the process of remediating the material weakness in internal control over financial reporting discussed in our Annual Report on Form 10-K for the year ended December 31, 2023 (as amended, the “Annual Report”), the completion of which should enable the Company’s certifying officers to again confirm the effectiveness of the Company’s disclosure controls and procedures discussed below. During the quarter ended September 30, 2024, the Company continued to make progress in redesigning and adding layers of review concerning its control procedures related to its transactions within inventory, mineral properties, income taxes, and non-routine transactions, including by adding human resources and engaging the assistance of third-party resources as deemed appropriate to assist management in its remediation efforts. The newly designed control procedures and additional remediation efforts will be tested over a sufficient number of instances with the intent to be considered effective in the coming quarter.

​

Evaluation of Disclosure Controls and Procedures

​

During the fiscal period covered by this report, our management, with the participation of the Chief Executive Officer and Chief Financial Officer, carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, to the extent of the material weakness identified in internal control over financial reporting and previously disclosed in Part II, Item 9A of the Company’s Annual Report that continued to exist as of September 30, 2024, the Company’s disclosure controls and procedures were not effective as of September 30, 2024.

​

In light of the foregoing, management performed additional analysis and other procedures to ensure that our unaudited consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP). Accordingly, management, including the Chief Executive Officer and Chief Financial Officer, believes that the unaudited consolidated financial statements included in this Quarterly Report on Form 10-Q fairly present, in all material respects, our financial position, results of operations, and cash flows as of and for the periods presented, in accordance with U.S. GAAP.

​

Changes in Internal Control Over Financial Reporting

​

Other than as described above, there was no change in the Company’s internal control over financial reporting during the quarter ended September 30, 2024, that materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

​

Limitations on Controls and Procedures

​

All disclosure controls and procedures and internal control over financial reporting processes and systems, no matter how well designed, have inherent limitations. Processes and systems deemed to be effective at any time can provide only reasonable assurance with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness for future periods are subject to the risk that controls may become inadequate due to changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. The Company conducts periodic evaluations of its internal controls to enhance, where deemed appropriate, its procedures and controls.

Item 1A. RISK FACTORS.

​

There were no material changes from the risk factors set forth under Part I, Item 1A, Risk Factors of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023. The risks described in our Annual Report, herein and other reports we have filed with the SEC are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially adversely affect our business, financial condition, cash flows and/or future results.

​

Item 3. DEFAULTS UPON SENIOR SECURITIES.

None.

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.
