GOLDEN, CO – / ACCESS NEWS WIRE/ – January 2, 2026 – Golden Minerals Company (“Golden Minerals,” “Golden”
or the “Company”) (OTCQB: AUMN and TSX: AUMN) announced that it has completed the sale of its wholly owned
Mexican subsidiaries, Servicios Velardeña S.A. de C.V. and GMC Equipos S.A. de C.V., to a privately held Mexican
group. The transaction was completed on December 30, 2025, for total consideration of approximately US$65,000.

Upon consummation of the transaction, Servicios Velardeña S.A. de C.V. and GMC Equipos S.A. de C.V. held net
operating losses, inflation-adjusted capital contributions, several liabilities including approximately US$60,000 in
past-due accounts payable, the remaining labor claim in Mexico of approximately US$56,000, and the Rodeo mining
concession, a mined-out project that includes an associated asset retirement obligation with a book liability value of
approximately US$450,000. Under Mexican law, the balance of the subsidiaries’ capital contribution accounts
(“CUCAs”) may be bought and sold. All funds related to the sale have been received.

Minerals to substantially eliminate its liabilities in the country and reduce ongoing overhead and administrative costs
to a minimum, while enabling the Company to focus on other regions.
