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. The report supports the previously disclosed mineral resource estimate, which includes 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 marks a key step in advancing the project toward development, as the company continues to expand its gold and silver production base across the Americas.
The Tartan Mine Project is part of McEwen's broader portfolio of assets in prolific mineral-rich regions. The company operates gold and silver mines in Nevada, the Timmins district of Ontario, Flin Flon in Manitoba, and the Deseado Massif in Santa Cruz province, Argentina. Additionally, McEwen is reactivating its gold-silver El Gallo Mine in Mexico. The Tartan resource estimate reinforces the company's position in Manitoba's Flin Flon greenstone belt, a historically productive mining region.
Beyond its precious metals operations, McEwen holds a 46.3% interest in McEwen Copper, which owns the large, long-life 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 project is designed to be one of the world's first regenerative copper mines and aims to achieve carbon neutrality by 2038, with 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 deploying PhotonAssay units globally. The company believes this technology is poised to become the new industry standard for assaying precious and base metals, with Paragon aiming to be a leading service provider.
Chairman and Chief Owner Rob McEwen, who has invested over US$250 million personally and takes a salary of $1 per year, aligns his interests with shareholders. A recipient of the Order of Canada, member of the Canadian Mining Hall of Fame, and winner of the EY Entrepreneur of the Year (Energy) award, McEwen's objective is to build MUX's profitability, share value, and ultimately implement a dividend policy, as he did while building Goldcorp Inc.
The Tartan Mine technical report filing provides transparency for investors as McEwen advances its growth strategy. The company's diversified asset base—spanning gold, silver, and copper—positions it to benefit from rising commodity demand.
