Its partner Cascadero Copper Corporation has announced an agreement to sell its interests in the Sarita Este and Desierto projects, among others, to Lumina Copper Corporation, an affiliate of First Quantum Minerals, Ltd., and Golden Minerals indicates it looks forward to working with First Quantum if the sale is completed. The company is planning a first-stage drill program at the Desierto concessions targeting potentially deep mineralization and expects to announce details of this drilling program later in September 2026.
Golden Minerals Company, an exploration-stage miner with projects in Argentina and Nevada, reported net income of $682 thousand for the quarter ended June 30, 2026, driven by $1.128 million of income from discontinued Mexican operations, while continuing operations recorded a loss of $446 thousand. Total assets were $2.9 million, including cash and cash equivalents of $2.5 million, against current liabilities of $1.0 million, resulting in shareholders’ equity of $1.9 million.
During the half-year, the company sold its remaining Mexican subsidiary Minera William for $1.2 million and completed a private placement of 3,740,000 shares at $0.2290 per share, increasing shares outstanding to 18,893,048. Management expects existing cash to fund operations into early–mid 2027 but cites substantial doubt about the company’s ability to continue as a going concern without additional asset sales or external financing.
Golden Minerals Company held its annual stockholder meeting on June 12, 2026, where two proposals were voted on. Of 15,153,048 common shares outstanding and entitled to vote as of the record date, 5,459,930 shares were present or represented by proxy, representing 36.03% of eligible shares.
Stockholders elected five directors — Jeffrey G. Clevenger, Pablo Castanos, Deborah J. Friedman, Kevin R. Morano and David H. Watkins — to serve until the 2027 annual meeting or until their successors are elected. Each director received more votes "for" than "withheld," with additional broker non-votes recorded.

Golden Minerals Company entered a Subscription Agreement with Streamline Metals Capital to sell 3,740,000 common shares at US$0.2290 per share in a private placement for aggregate gross proceeds of approximately US$856,463, subject to Toronto Stock Exchange approval. The company also sold all shares of Minera William, S.A. de C.V., owner of the El Par de Tres 2 property and a 2.0% net smelter returns royalty on the San Diego property, to purchasers including Streamline and Horizon Silver Resources for US$1,200,000 in cash.
For the quarter ended March 31, 2026, Golden Minerals reported a net loss of US$0.6 million, or US$0.04 per share, with cash and cash equivalents of US$0.9 million and no debt. Management states that, even after the Minera William sale and expected private placement proceeds, existing cash resources are only expected to fund operations into early 2027, and the company is evaluating further asset sales, a potential sale of the company, partnerships, or additional equity or external financing.
Golden Minerals Company reported a net loss of $0.6 million for the quarter ended March 31, 2026, an improvement from a $1.2 million loss a year earlier. Operating costs totaled $0.6 million, including $0.5 million of administrative expense and $0.06 million of exploration expense.
Income from discontinued operations was $14,000, compared with a $0.4 million loss in the prior-year period. Cash and cash equivalents were $0.9 million at quarter-end, with current liabilities of $0.9 million, leaving total assets of $1.3 million and shareholders’ equity of $0.3 million.
Subsequent to quarter-end, the company sold Minera William, S.A. de C.V. for $1.2 million and agreed to a private placement of 3,740,000 shares at $0.2290 per share for expected gross proceeds of about $0.86 million. Management expects these proceeds to fund operations into early 2027, but the lack of revenue-generating operations means additional financing will be needed thereafter, and substantial doubt about the company’s ability to continue as a going concern remains.
Golden Minerals Company is asking stockholders to vote at its 2026 annual meeting on June 12, 2026 at the Embassy Suites by Hilton Denver International Airport in Denver. Holders of common stock at the close of business on April 15, 2026, when 15,153,048 shares were outstanding, may vote.

Golden Minerals Company reported full-year 2025 results and highlighted serious liquidity pressures. Cash and cash equivalents were about $1.3 million at December 31, 2025, down from $3.2 million a year earlier, with current assets of roughly $1.9 million and current liabilities of about $1.4 million.
The company expects cash expenditures of approximately $2.3 million over the twelve months ending December 31, 2026, mainly for administrative costs and limited exploration. Management states that, without new cash inflows, existing cash resources are expected to be exhausted in the second quarter of 2026 and that failure to secure additional capital or a sale of the company would force it to cease operations and liquidate.
Golden Minerals Company has transformed into a pure exploration-stage miner after selling its Velardeña mines and other non-core assets, and now holds gold-silver-copper exploration projects in Argentina and Nevada with no mineral reserves under S‑K 1300.
The company warns of substantial doubt about its ability to continue as a going concern. With only about $0.9 million in cash at March 31, 2026 and no producing mines, it expects its cash to be exhausted in the second quarter of 2026 unless it secures new funding, sells assets, or completes a strategic transaction.
Golden Minerals is advancing joint venture structures on the Sarita Este/Desierto projects in Argentina and the Sand Canyon project in Nevada, where prior drilling has outlined encouraging but still non-reportable mineralization at Sarita Este. The firm was delisted from the NYSE American in 2024 and now trades on the OTCQB and TSX, highlighting financing and liquidity challenges alongside intense industry competition and significant country, environmental and regulatory risks.
