1. Basis of Preparation of Financial Statements and Nature of Operations

Golden Minerals Company (the “Company”, “we” “our” or “us”), a Delaware corporation, has prepared these unaudited interim condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”). The interim condensed consolidated financial statements do not include all disclosures required by GAAP for annual financial statements, but in the opinion of management, include all adjustments necessary for a fair presentation. Certain prior period amounts may have been reclassified to conform to current classifications. Interim results are not necessarily indicative of results for a full year; accordingly, these interim condensed consolidated financial statements should be read in conjunction with the annual financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, filed with the SEC on March 19, 2024 (the “2023 Annual Report”).

The Company is a mining company, holding a 100% interest in the Rodeo property in Durango State, Mexico (the “Rodeo Property”), a 100% interest in the Velardeña and Chicago precious metals mining properties and associated oxide and sulfide processing plants in the state of Durango, Mexico (the “Velardeña Properties”), which are subject to a purchase agreement with a private Mexican entity (see Note 2), a 100% interest in the El Quevar advanced exploration property in the province of Salta, Argentina (see Note 8), and a diversified portfolio of precious metals and other mineral exploration properties located primarily in or near historical precious metals producing regions of Mexico, Argentina and Nevada. The Velardeña Properties, the Yoquivo property and the El Quevar advanced exploration property are the Company’s only material properties.

We concluded mining operations at the Rodeo Property in June 2023. We commenced mining activities at the Velardeña Properties in December 2023; however, mining operations were shut down in February 2024 because the initial performance of the mine and processing plant did not meet the expected results. The Company continued to process material at the sulfide plant through the end of March, 2024 at which time the plant was also shut down. Both assets are being held for sale and in a care and maintenance state. We continue to evaluate and search for mining opportunities in North America (including Mexico) with near-term prospects of mining. We are also focused on advancing our Yoquivo exploration property in Mexico, and our El Quevar advanced exploration property in Argentina. We are holding an additional portfolio of approximately 11 properties located in Mexico, Nevada and Argentina for sale or advancement when possible.

The Company is considered an exploration stage issuer under the criteria set forth by the SEC under Subpart 1300 of Regulation S-K (“S-K 1300”) as the Company has not yet demonstrated the existence of mineral reserves at any of the Company’s properties. As a result, and in accordance with GAAP for exploration stage companies, all expenditures for exploration and evaluation of the Company’s properties are expensed as incurred. As such, the Company’s financial statements may not be comparable to the financial statements of mining companies that have proven and probable mineral reserves. Such companies would typically capitalize certain development costs including infrastructure development and mining activities to access the ore. The capitalized costs would be amortized on a units-of-production basis as reserves are mined. The amortized costs are typically allocated to inventory and eventually to cost of sales as the inventories are sold. As the Company does not have proven and probable mineral reserves, substantially all expenditures at the Company’s Rodeo Property and the Velardeña Properties for mine construction activity, as well as operating costs associated with the mill facilities, and for items that do not have a readily identifiable market value apart from the mineralized material, have been expensed as incurred. Such costs are charged to cost of metals sold or project expense during the period depending on the nature of the costs. Certain costs may be reflected in inventories prior to the sale of the product. The Company cannot be certain that any deposits at any of its properties will ever be confirmed or converted into S-K 1300 compliant “reserves.”

Reverse Stock Split

On May 26, 2023, the Company’s Board of Directors approved a reverse stock split (the “Reverse Stock Split”) of the Company’s common stock, par value $0.01 per share, at a ratio of one-for-25 shares and a reduction in the total number of authorized shares of common stock of the Company from 350,000,000 shares to 28,000,000 shares (the

“Authorized Shares Reduction”), each effective as of June 9, 2023. To effect the Reverse Stock Split and the Authorized Shares Reduction, the Company filed an amendment to the Company’s Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware on May 30, 2023.

Accordingly, all share and per share data (including share and per share information related to share-based compensation and outstanding warrants), number of shares outstanding and other common stock equivalents for the periods presented in the accompanying interim condensed consolidated financial statements and notes thereto have been adjusted retroactively, where applicable, to reflect the Reverse Stock Split.
