NOTE 2 OPERATING SEGMENT REPORTING

The chief operating decision-maker (“CODM”) is the executive leadership team of the Company. The CODM reviews operating results, assesses performance and makes decisions about allocation of resources to these segments at the major mine/project where the economic characteristics of the individual mines, or by investee for those which are considered a reportable segment. As a result, these operating segments also represent the Company’s reportable segments.

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 and an allocation of other segment items for all segments except for the McEwen Copper and MSC segments, which are evaluated based on the attributable equity income or loss pickup. The CODM uses segment gross profit (loss) and profit (loss) before taxes, or income (loss) from equity method investments, to allocate resources (including employees, property, and financial or capital resources) for each segment. CODM predominantly considers such measures in the annual budget and forecasting process. The CODM considers budget-to-actual variances for operating segments on a quarterly basis to support resource allocation and performance evaluation.

Gold and silver sales and production costs applicable to sales for the reportable segments are reported net of intercompany transactions. Capital expenditures include costs capitalized in mineral property interests and plant and equipment in the respective periods.

Significant information relating to the Company’sreportable operating segmentsfor the periods presented is summarized in the tables below:

On March 10, 2025, the Company acquired 5,181,347 units of Goliath Resources Limited (TSX-V: GOT) (“Goliath Resources”) in exchange for 868,056 common shares of the Company. Each unit consists ofone common share andone-half ofone warrant. Each whole warrant entitles the Company to purchaseone common share of Goliath Resources at a price of C$2.50 for a period oftwelve months following the closing of the offering, expiring on March 10, 2026. Following the closing, as at March 10, 2025, the Company held an approximate 4% ownership interest in Goliath Resources. The Company recognized a day one gain of$0.9 million on the difference between the transaction price and fair value of units received. The warrants expired unexercised on March 10, 2026, resulting in the recognition of a loss of $0.5 million during the three-month period ended March 31, 2026.

On March 27, 2025, the Company participated intwo private placement offerings by Canadian Gold (TSX-V: CGC), acquiring 8,823,529 common shares and 2,941,176 units for a total investment of $1.4 million.

Following the closing, as at March 27, 2025, the Company held an approximate 6% ownership interest in Canadian Gold. The Company recognized a day one gain of$0.5 million on the difference between the transaction price and fair value of units received. The warrants expired unexercised upon acquisition of Canadian Gold on January 5, 2026, resulting in the recognition of a loss of$0.7 million during the three-month period ended March 31, 2026.

The Company didnot have any inventory write-downs during the three months ended March 31, 2026, and 2025.

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 or economically viable deposits 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 Complex and San José properties have proven and probable reserves estimated in accordance with Regulation S-K 1300. The mineral properties associated with the Fox Complex include the Froome and Black Fox mines, the Grey Fox deposit, and the Stock property. The Fox Complex is depleted and depreciated using the units-of-production method over the estimated production for the remaining life of the mine, as the project does not have proven and probable reserves that conform to the guidance under Regulation 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 three months ended March 31, 2026, no indicators of impairment were noted for any of the Company’s mineral property interests.

NOTE 9 EQUITY METHOD INVESTMENTS

The Company accounts for investments over which it exerts significant influence but does not control through majority ownership using the equity method of accounting. In applying the equity method of accounting to the Company’s investments in McEwen Copper, Paragon and MSC, the financial statements of Paragon and MSC, which are originally prepared in accordance with IFRS Accounting Standardsas issued by the International Accounting Standards Board, have been adjusted to conform with U.S. GAAP.

A reconciliation of the Company’s equity method investments as at March 31, 2026, and December 31, 2025, is as follows:

Equity method investment in McEwen Copper

A summary of the operating results for McEwen Copper for the three months ended March 31, 2026, and 2025, is as follows:

(1) Interest and other income (expenses) include interest on term debt and finance-related income and expenses.

Changes in the Company’s investment in McEwen Copperfor the three months ended March 31, 2026, and for the year ended December 31, 2025, are as follows:

A summary of the key assets and liabilities of McEwen Copper as at March 31, 2026, and December 31, 2025, is as follows:

As at March 31, 2026, the Company's investment in McEwen Copper exceeded its proportionate share of the underlying net assets by $199.1 million. This basis difference is attributable to equity method goodwill and not amortized.

Equity method investment in MSC

A summary of the operating results for MSC for the three months ended March 31, 2026, and 2025, is as follows:

(1) Other income includes foreign exchange gains and losses, accretion of asset retirement obligations, and other finance-related income*.*

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 three months ended March 31, 2026, and for the year ended December 31, 2025, are as follows:

A summary of the key assets and liabilities of MSC as at March 31, 2026, and December 31, 2025, is as follows:

As at March 31, 2026, the Company’s investment in MSC exceeded its proportionate share of the underlying net assets by $29.2 million. This basis difference is primarily attributable to mineral property interests and amortized on a unit-of-production basis.

Equity method Investment in Paragon

On December 9, 2025, the Company completed the transaction to acquire 27.32% equity interest in Paragon, a provider of advanced analytical services to the mining industry. The transaction involved a share exchange in which the Company acquired a total of 8,742,880 Paragon shares in exchange for 709,992 common shares of the Company. The total fair value of the transaction was $13.7 million, based on the Company's closing share price of $19.35 per share on December 9, 2025.

The Company's investment in Paragon exceeded its proportionate share of the underlying net assets by $12.5 million. This basis difference is attributable to equity-method goodwill and is not amortized.

Subsequent to the acquisition, on December 15, 2025, an existing shareholder exercised 400,000 warrants to acquire an equivalent number of common shares of Paragon. As a result, the Company’s ownership in Paragon decreased from 27.3% to 27.0%. This reduction in ownership is accounted for as a notional disposition of shares, resulting in a $0.2 million dilution loss.

Due to the timing of the availability of financial information, the Company recognizes its share of the earnings of Paragon on a three-month lag basis. The Company monitors the investee for material intervening events and concluded that no material adjustments were necessary for the three months ended March 31, 2026.

A summary of the operating results for Paragon for the period from December 9, 2025, to December 31, 2025, is as follows:

Changes in the Company’s investment in Paragon for the three months ended March 31, 2026, and December 31, 2025, are as follows:

NOTE 10 DEBT

Term loan facility

On January 31, 2025, the Company amended its Third Amended and Restated Credit Agreement (“ARCA”). The amendments refinanced the outstanding $40.0 million loan and included the following revisions:

The consideration issued for the maintenance, continuation, and extension of the maturity date of the loan was accounted for as debt issuance costs, which were capitalized as deferred financing costs within long-term debt. These costs are being amortized as interest expense over the term of the debt using the effective interest method.

Following the issuance of the Convertible Notes (as defined below), on February 21, 2025, the Company voluntarily repaid $20.0 million in principal under the ARCA.

Total interest expense related to the term loan for the three months ended March 31, 2026, was $0.5 million, at an effective interest rate of 11.16%. This included $0.5 million in interest at the contractual coupon rate of 9.75% and $34 thousand related to the amortization of the debt issuance costs. For the three months ended March 31, 2025, total interest expense related to the term loan was $0.8 million, at an effective interest rate of 11.16% and was comprised of$0.8 million related to the interest coupon at the contractual rate of 9.75% and$26 thousand related to the amortization of the debt issuance costs.

Convertible senior unsecured notes

On February 11, 2025, the Company issued $110.0 million in aggregate principal amount of 5.25% convertible senior unsecured notes due 2030 (“Convertible Notes”). The net proceeds from the issuance of the Convertible Notes, after deducting offering-related costs of $4.2 million and cost of a Capped Call Transaction (defined hereinafter) of $15.1 million, were approximately $90.7 million. The Convertible Notes bear interest at the annual rate of 5.25%, payable semiannually in arrears on August 15 and February 15 of each year, beginning on August 15, 2025, and will mature on August 15, 2030, unless earlier converted, redeemed or repurchased by the Company.

The Convertible Notes will be convertible into cash, shares of the Company’s common stock or a combination thereof, at the Company’s election. The initial conversion rate is 88.9284 shares of common stock per each $1,000 principal amount of Convertible Notes, which is equivalent to an initial conversion price of approximately $11.25 per share, subject to adjustment pursuant to the terms of the Indenture governing the Convertible Notes (the “Indenture”). The conversion rate may not exceed 115.6069 shares under the terms of the Indenture.

The Convertible Notes may be converted at any time prior to May 15, 2030, only under the following circumstances:

On or after May 15, 2030, until the close of business on the second trading day before the maturity date, holders may convert their notes at any time, regardless of prior conditions.

The Convertible Notes will be redeemable, in whole or in part, at the Company’s option at any time from August 21, 2028, through the 46th trading day prior to maturity, provided that the Company’s common stock has traded at or above 130% of the conversion price for at least 20 trading days within any 30 consecutive trading day period ending on the day before the redemption notice. The redemption price will be equal to 100% of the principal amount of the notes redeemed, plus accrued and unpaid interest up to, but excluding, the redemption date. No sinking fund is provided for the notes.

If the Company undergoes a “fundamental change”, as defined in the Indenture, and subject to certain conditions and exceptions, holders may require the Company to repurchase all or a portion of their notes for cash at a price equal to 100% of the principal amount, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

The Indenture contains other customary terms and covenants, including certain events of default. The Convertible Notes are accounted for as a single liability in its entirety. No portion of the proceeds was attributed to the conversion option, as the embedded feature did not require bifurcation. In connection with the above-noted transaction, the Company incurred approximately $4.2 million in expenses accounted for as debt issuance costs, which were capitalized as deferred costs within long-term debt. These costs are being amortized as interest expense over the term of the debt using the effective interest method. The total interest expense related to the Convertible Notes for the three months ended March 31, 2026, was $1.6 million at an effective interest rate of 6.33%, and was comprised of $1.4 million related to the contractual interest coupon and $0.2 million related to the amortization of the debt issuance costs. For the three months ended March 31, 2025, total interest expense related to the Convertible Notes was$0.9 million at an effective interest rate of 6.33% and was comprised of$0.8 million related to the contractual interest coupon and$0.1 million related to the amortization of the debt issuance costs.

As of March 31, 2026, the Convertible Notes have a net carrying amount of $106.6 million and an estimated fair value of $227.5 million. The fair value is based on Level 1 quoted prices in active markets for identical securities.

Capped call transactions

In connection with the offering of the Convertible Notes, the Company used approximately $15.1 million of the net proceeds from the offering of the Convertible Notes to pay the cost of the Capped Call Transactions. The Capped Call Transactions cover, subject to customary anti-dilution adjustments, the aggregate number of shares of common stock that initially underlie the Convertible Notes, and are expected generally to reduce potential dilution to the common stock upon any conversion of the Convertible Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted Convertible Notes, as the case may be, with such reduction and/or offset subject to a cap of $17.30. The Capped Call Transactions are separate transactions entered into by the Company and are not part of the terms of the Convertible Notes.

As the Capped Call Transactions are freestanding instruments which are both indexed to the issuer’s own stock and classified in shareholders’ equity, the premiums paid in the Capped Call Transactions were classified as a reduction to the additional paid-in capital and will not be remeasured as long as they continue to meet the conditions for equity classification.

NOTE 11 RECLAMATION AND REMEDIATION LIABILITIES

The Company is responsible for the reclamation of certain past and future disturbances at its properties. As at March 31, 2026, the reclamation and remediation liability balances at the properties subject to these obligations were $21.1 million at the Gold Bar, Tonkin and Lookout Mountain properties in Nevada, $18.5 million at the Fox Complex and $6.3 million at the El Gallo mine in Mexico (December 31, 2025 – $20.8 million, $18.6 million and $6.4 million, respectively).

A reconciliation of the Company’s reclamation and remediation liabilities for the three months ended March 31, 2026, and for the year ended December 31, 2025, is as follows:

Pursuant to an Arrangement Agreement, the Company issued 2,943,766 common shares and 1,526,786 subscription receipts at a deemed price of $19.60 per share, for total consideration of $87.7 million. The number of instruments issued was determined based on an exchange ratio of 0.0225 applied to Canadian Gold shares outstanding. Refer toNote 14 Related Party Transactions andNote 18 Canadian Gold Corp. Acquisitionfor additional details.

NOTE 13 NET INCOME (LOSS) PER SHARE

Basic net income (loss) per share is computed by dividing the net income (loss) by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is calculated using the treasury stock method for options and warrants and the if-converted method for the convertible senior unsecured notes. Under the if-converted method, interest expense, net of tax, is added back to net income and the weighted-average shares outstanding are increased by the shares issuable upon conversion of the notes. In applying the treasury stock method, instruments with an exercise price greater than the average quoted market price of the common shares for the period are not included in the calculation, as the impact would be anti-dilutive.

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 because potentially dilutive instruments, including the conversion option embedded in the convertible senior unsecured notes, are generally anti-dilutive during such periods.

Below is a reconciliation of the basic and diluted weighted average number of common shares and the computations for basic and diluted net income (loss) per share for the three months ended March 31, 2026, and 2025:

For the three months ended March 31, 2026, the weighted average number of common shares was increased by 850,705 incremental shares to reflect the impact of dilutive instruments.

Convertible senior unsecured notes were assumed to have been converted at the beginning of the period. Accordingly, $1.1 million of interest expense related to the notes, net of tax, was added back to net income, and the weighted-average number of common shares outstanding was increased by 12,716,759 shares representing the shares issuable upon conversion.

For the three months ended March 31, 2025, 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 15 FAIR VALUE ACCOUNTING

The hierarchy of fair value measurements assigns a level to fair value measurements based on the inputs used in the respective valuation techniques. The levels of the hierarchy, as defined below, give the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs.

● Level 1 is defined as observable inputs such as quoted prices in active markets for identical assets. The Company’s Level 1 assets include investments in equity securities, which are exchange-traded and are valued using quoted market prices in active markets.

● Level 2 is defined as observable inputs other than Level 1 prices. These include quoted prices for similar assets or liabilities in an active market, quoted prices for identical assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Company’s Level 2 assets include investments in share purchase warrants with fair value determined using the Black-Scholes option pricing model and inputs from observable market data, including historic volatility.

● Level 3 is defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The Company’s Level 3 assets include investments in share purchase warrants of McEwen Copper with fair value determined using the Black-Scholes option pricing model and unobservable inputs. Significant unobservable inputs used in Level 3 fair value measurements developed internally by the Company as of March 31, 2026 included the estimated fair value of McEwen Copper shares of $35 per share.

The following table presents the Company’s financial assets and liabilities that are recorded at fair value in the accompanyingConsolidated Balance Sheets:

The fair value measurement of the Company’s convertible senior unsecured notes is presented inNote 10 Debt and is not included in the table above. The carrying value of the term loan approximates its fair value based on its recent refinancing.

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

The following table presents the reconciliation for the Company’s assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3):

The terms of the facilities carry an average annual financing fee of 2.4% and require an average deposit of 7.2%. Surety bonds are available for draw-down by the beneficiary in the event the Company does not fulfil its reclamation obligations. If the specific reclamation requirements are met, the beneficiary of the surety bonds will release the instrument to the issuing entity.

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.

For the three months ended March 31, 2026, and 2025, the Company used the annual effective tax rate method to calculate its tax provision. The tax provision also includes discrete adjustments including the amortization of the flow-through shares premium and changes to valuation allowances on various jurisdictions.
