McEwen Mining MUX has significantly expanded the gold resource at its Grey Fox deposit, part of the Fox Complex in Northern Ontario.
Since the last estimate in 2021, Grey Fox's indicated gold resource has increased by 32% to 1.54 million ounces, while inferred resources have nearly doubled to 458,000 ounces. The total gold resource has grown by nearly 50% over three years.
"Our investment in exploration on the Fox Complex properties has successfully expanded our gold resources, which will enable us to both increase annual production and extend the mine life," said Chairman Rob McEwen.
The company credits its success to extensive exploration drilling and higher gold prices. The $2,000 per ounce calculation allowed for a lower cut-off grade, from 2.30 g/t Au to 1.60 g/t Au.
The Grey Fox deposit is located approximately 3 kilometers southeast of McEwen's Black Fox Mine and 75 kilometers east of Timmins, Ontario. It lies within the prolific Porcupine-Destor Fault Zone, a region historically associated with over 110 million ounces of gold production.
The deposit consists of six zones, with the Gibson zone showing the most significant growth—its indicated resources increased by 181% to 290,000 ounces, while inferred resources rose by 80% to 245,000 ounces. The Whiskey-Jack zone also stands out, with 97% of its mineralization categorized as indicated, totaling 116,000 ounces at a high grade of 5.7 g/t.
The discovery cost for the increased resources was remarkably low at $14.46 per ounce, aligned with the firm's cost-conscious approach.
The firm has outlined its production and cost guidance for 2025. The company expects consolidated production to range between 120,000 and 140,000 gold equivalent ounces (GEOs) – similar to FY 2024 production, which achieved 135,900 GEOs.
The lower end of the range reflects the planned transition from the Froome mine to the Stock mine at the Fox Complex, with commercial production from Stock anticipated in early 2026.
Despite permitting delays, McEwen remains confident in its long-term strategy to enhance production and extend the mine life at its Fox Complex, supported by the continued growth of resources at Grey Fox and other deposits.
