McEwen (NYSE: MUX) (TSX: MUX) announced it has filed an independent National Instrument 43-101 technical report for its Tartan Mine Project in Manitoba, supporting the previously reported mineral resource estimate of 308,900 ounces of gold in indicated resources and 302,700 ounces in inferred resources, with an effective date of Dec. 31, 2025. The filing underscores the company's commitment to transparency and regulatory compliance, providing investors with a verified assessment of the project's potential. The Tartan Mine Project is part of McEwen's growing portfolio of gold and silver assets in the Americas, which includes operations in Nevada, Ontario, Manitoba, and Argentina.
According to the press release, McEwen shares trade on both the NYSE and TSX under the ticker MUX. The company provides its shareholders with exposure to a growing base of gold and silver production in addition to a very large copper development project, all in the Americas. The gold and silver mines are located in prolific mineral-rich regions, including the Cortez Trend in Nevada, the Timmins district of Ontario, Flin Flon in Manitoba, and the Deseado Massif in Santa Cruz province, Argentina. McEwen is also reactivating its gold-silver El Gallo Mine in Mexico.
The company has a 46.3% interest in McEwen Copper, which owns the large, long-life, advanced-stage Los Azules copper development project in San Juan province, Argentina. According to the last financing for McEwen Copper, the implied value of McEwen's ownership interest is US$456 million (US$7.67 per share). The Los Azules copper project is designed to be one of the world's first regenerative copper mines and carbon neutral by 2038. Its Feasibility Study results were announced in the press release dated October 7, 2025.
McEwen also recently purchased 27.3% of Paragon Advanced Labs Inc., a newly listed public company that is deploying PhotonAssay units around the world, a technology that the company believes is poised to become the new industry standard for assaying precious and base metals, with Paragon aiming to be one of the leading service providers.
Chairman and Chief Owner Rob McEwen has invested over US$250 million personally and takes a salary of $1 per year, aligning his interests with shareholders. He is a recipient of the Order of Canada, a member of the Canadian Mining Hall of Fame, and a winner of the EY Entrepreneur of the Year (Energy) award. His objective is to build MUX's profitability, share value, and ultimately implement a dividend policy, as he did while building Goldcorp Inc.
