GOLDEN MINERALS ANNOUNCES COMPLETION OF SALE OF VELARDENA PROPERTIES

Golden Minerals Company has completed the previously announced sale of its Velardena oxide processing plant and water wells, located in Durango, Mexico, to a privately held Mexican company.

The transaction closed on Oct. 10, 2025, with a total purchase price of $3.0-million (U.S.) plus applicable value-added tax. The buyer had made payments of approximately $2.95-million, and the final balance of approximately $28,000 (U.S.) plus VAT has been received, marking the full and successful completion of the sale.

The Velardena buyer had previously acquired the Velardena and Chicago mines, related mining equipment, and the sulphide processing plant under separate agreements. With this closing, Golden has fully divested its Velardena operations, allowing the company to concentrate its resources on advancing its exploration portfolio.
