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 line item in the below table and are provided for reconciliation purposes.

The CODM reviews segment income or loss, defined as gold and silver sales less production costs applicable to sales, depreciation, and depletion, advanced projects, and exploration costs, for all segments except for the MSC and McEwen Copper segments, which are evaluated based on the attributable equity income or loss. 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’s reportable operating segments for the periods presented is summarized in the tables below:

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

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.

NOTE 15 FAIR VALUE ACCOUNTING

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

Assets and liabilities measured at fair value on a recurring basis

The following 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 June 30, 2024 and December 31, 2023, as reported in theConsolidated Balance Sheets:

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 June 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 June 30, 2024, the Company had surety facilities in place to cover its bonding obligations, which include $33.3 million of bonding in Nevada and $7.3 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 June 30, 2024, the Company recorded $2.5 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 records the revenue from these shipments based on the contract price at the time of delivery to the customer. During the three and six months ended June 30, 2024, the Company recorded revenue of $0.4 million and $0.8 million, respectively (three and six months ended June 30, 2023 – $0.6 million and $1.0 million, respectively) related to the gold stream sales.

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.
