McEwen Inc. (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 provides formal documentation of the resource estimate, which is a key step for advancing the project toward development.
The Tartan Mine Project is part of McEwen's growing portfolio of gold and silver production assets, which also includes operations in Nevada, Ontario, Manitoba, Argentina, and Mexico. The company's gold and silver mines are located in prolific mineral-rich regions, such as 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.
Beyond gold and silver, McEwen holds 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, with its Feasibility Study results announced in a 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. The company believes this technology 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.
The company is led by Chairman and Chief Owner Rob McEwen, who 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.
For investors, the filing of the NI 43-101 technical report provides greater confidence in the Tartan Mine Project's resource base, potentially de-risking the project and supporting McEwen's growth strategy. The confirmation of nearly 612,000 ounces of gold resources across indicated and inferred categories strengthens McEwen's position in the gold mining sector, while its stake in the Los Azules copper project offers exposure to the growing demand for copper in renewable energy and electric vehicle markets. The company's focus on regenerative mining and carbon neutrality aligns with industry trends toward sustainable practices, which may appeal to environmentally conscious investors. The recent investment in Paragon Advanced Labs also underscores McEwen's interest in innovative technologies that could improve efficiency and reduce costs in mineral assaying.
