McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) announced the filing of 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 December 31, 2025. The filing represents a key milestone for the project, which is part of McEwen's growing gold and silver production base in the Americas.
The Tartan Mine Project is located in the prolific Flin Flon mining district of Manitoba, a region known for its rich mineral deposits. The technical report provides detailed geological and engineering data, confirming the project's potential to contribute to McEwen's overall gold output. The company operates mines in Nevada, Ontario, Manitoba, and Argentina, and is also reactivating its El Gallo Mine in Mexico.
McEwen's portfolio includes a 46.3% interest in McEwen Copper, which owns the advanced-stage Los Azules copper project in Argentina. 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. According to the last financing for McEwen Copper, the implied value of McEwen's ownership interest is US$456 million, or US$7.67 per share. The feasibility study results for Los Azules were announced in a press release dated October 7, 2025.
In addition to its mining assets, McEwen recently purchased a 27.3% stake in Paragon Advanced Labs Inc., a public company deploying PhotonAssay units globally. This technology is expected to become a new industry standard for assaying precious and base metals, with Paragon aiming to be a leading service provider.
Chairman and Chief Owner Rob McEwen has invested over US$250 million personally in the company 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 an EY Entrepreneur of the Year (Energy) award winner. His objective is to build MUX's profitability and share value, ultimately implementing a dividend policy, as he did while building Goldcorp Inc.
