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, Canada. The report supports 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 is a key step in advancing the project and underscores McEwen's commitment to expanding its gold production footprint in the Americas.
The Tartan Mine Project is part of McEwen's portfolio of gold and silver mines located in prolific mineral-rich regions, including the Cortez Trend in Nevada, the Timmins district of Ontario, and the Deseado Massif in Argentina. The company also holds a 46.3% interest in McEwen Copper, which owns the advanced-stage Los Azules copper development project in 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 be carbon neutral by 2038. Feasibility Study results were 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 worldwide. 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 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.
The filing of the NI 43-101 technical report is important because it provides investors with a verified and independent assessment of the Tartan Mine Project's mineral resources, which is critical for project financing and development decisions. For the mining industry, this report adds to the growing resource base in Manitoba's Flin Flon district, a historically productive region. For investors, the confirmed gold resources strengthen McEwen's production pipeline and could enhance the company's valuation, especially given the current high gold price environment. The news also highlights McEwen's diversified portfolio across gold, silver, and copper, offering exposure to multiple commodities.
