McEwen Mining Refiles Fox Complex Technical Report Following Regulatory Review

McEwen Inc. (NYSE: MUX) (TSX: MUX) has amended and refiled its technical report on the Fox Complex mineral resources in Ontario, Canada, following a review by the Ontario Securities Commission. The company announced the refiling of its "NI 43-101 Technical Report on the Mineral Resources Estimate of the Fox Complex, Ontario, Canada," which was originally filed on April 4, 2025, as part of the OSC's continuous disclosure program.

The updated technical report now includes additional information required under Items 16 to 22 of Form 43-101F1 for advanced properties. A significant change involved replacing John Ryan Cox as a co-author to ensure full compliance with Qualified Person requirements under Canadian securities regulations.
