McEwen Mining Refiles Fox Complex Technical Report Following Regulatory Review

McEwen Inc. has amended and refiled its technical report on the Fox Complex mineral resources following a review by the Ontario Securities Commission. The company, trading on both the New York Stock Exchange and Toronto Stock Exchange under the symbol MUX, announced the refiling of its NI 43-101 Technical Report on the Mineral Resources Estimate of the Fox Complex located in Ontario, Canada. This action was taken as part of the OSC's continuous disclosure program review process, ensuring that mining companies maintain proper disclosure standards for investors and stakeholders.

The updated technical report now includes additional information required under Items 16 to 22 of Form 43-101F1, which applies specifically to advanced properties. These requirements cover detailed technical information about mineral resources, mining methods, processing methods, infrastructure, and other critical aspects of mineral project development. The company also replaced John Ryan Cox as a co-author to ensure full compliance with Qualified Person requirements under National Instrument 43-101 standards. Despite these administrative changes, McEwen emphasized that the actual Mineral Resources statements for the Fox Complex remain completely unchanged from the original April 4, 2025 filing.

This regulatory compliance matter holds significance for investors and market participants who rely on accurate and complete technical reporting. The Ontario Securities Commission's continuous disclosure program serves as an important regulatory mechanism to ensure that mining companies provide transparent and standardized information to the market.
