McEwen Inc. (NYSE: MUX) (TSX: MUX) has announced positive results from the Pre-Feasibility Study (PFS) for its wholly owned Grey Fox Project near Timmins, Ontario. The study highlights the project’s potential to significantly increase production at the Fox Complex and extend mine life through 2041. With Grey Fox contributing to production, the Fox Complex is projected to reach approximately 100,000 ounces of gold production in 2029 and average 87,000 ounces annually from 2028 through 2041. This supports McEwen’s goal of increasing total annual production to 250,000-300,000 gold equivalent ounces by 2030.
The study estimates initial capital expenditures of $181 million and outlines strong project economics, including a post-tax net present value of $282 million and a 25% internal rate of return at a gold price of $3,000 per ounce. At a gold price of $4,500 per ounce, post-tax NPV increases to $841 million with a 55% IRR and a 2.3-year payback period. Management said current precious metals prices are expected to generate sufficient cash flow to largely fund development internally while leveraging existing Fox Complex infrastructure, including the Stock Mill, tailings facilities and workforce.
