McEwen Mining Files NI 43-101 Technical Report for Tartan Mine Project, Confirming Gold Resources

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 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 December 31, 2025. This filing provides investors with a verified assessment of the project's gold potential, reinforcing McEwen's position in the gold mining sector.

The Tartan Mine Project is part of McEwen's growing portfolio of gold and silver production assets, which also include operations in Nevada, Ontario, Manitoba, Argentina, and Mexico. The company's strategy focuses on expanding its resource base in prolific mineral-rich regions. The filing of the technical report is a routine but important step for mining companies, as it provides transparency and credibility to the resource estimates, which are critical for project financing and development decisions.

McEwen also holds a 46.3% interest in McEwen Copper, which owns the 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 project is designed to be one of the world's first regenerative copper mines and aims to be carbon neutral by 2038.

In addition, McEwen recently purchased 27.3% of Paragon Advanced Labs Inc., a newly listed public company deploying PhotonAssay units globally. The company believes this technology could become the new industry standard for assaying precious and base metals.

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 significant for investors and the industry as it provides a reliable and independent assessment of the Tartan Mine Project's gold resources. This can impact the company's valuation and future production plans. For the mining sector, such reports are essential for maintaining investor confidence and facilitating capital allocation. The confirmation of resources may also affect local economies in Manitoba through potential job creation and mining activity.
