McEwen Inc. Reports Significant Increase in Gold Resources at Grey Fox Project
On January 20, 2026, McEwen Inc. (NYSE/TSX: MUX) announced its Year-End 2025 Mineral Resource Estimate for the Grey Fox Project, part of the company's Fox Complex located in Timmins, Ontario. The latest report reveals a total of 1.9 million Indicated gold ounces and 436,000 Inferred gold ounces, calculated based on a gold price of US$3,000 per ounce. This update indicates a robust potential for resource expansion, driven by recent acquisitions and ongoing exploration efforts.
Key Highlights of the 2025 Grey Fox Resource
- Indicated Resources: 1,892,000 gold ounces (19,474,000 tonnes at 3.02 gpt gold)
- Inferred Resources: 436,000 gold ounces (5,101,000 tonnes at 2.66 gpt gold)
- +23% increase in Indicated Resources compared to Year-End 2024
- Stroud Property acquisition holding a historical resource of approximately 270,000 gold ounces
- New drill results, including 10.1 gpt gold over 5.8 meters
- Upcoming Pre-Feasibility Study (PFS) expected in Q2 2026
Resource Expansion and Mining Strategy
The potential for resource growth at the Grey Fox Project is supported by three critical factors: the recent acquisition of the adjacent Stroud Property, new drilling data received post cut-off for the resource estimate, and ongoing optimization of both mine and plant designs. The Grey Fox Project plays a pivotal role in McEwen's ambition to double production by 2030, transitioning the Fox Complex into a long-lasting mining operation.
Previously envisioned only as an underground project, the current strategy balances underground and open-pit mining methodologies. This dual approach aligns with the phased development plan outlined in the forthcoming PFS, enhancing long-term project viability.
Initial Underground Mining Opportunities
The McEwen team has pinpointed two areas—Gibson Zone and Whiskey Jack—where accelerated underground mining could yield significant returns. The Gibson Zone, located near existing underground infrastructure, contains:
- Indicated Resources: 393,000 gold ounces (4.5 million tonnes at 2.72 gpt gold)
- Inferred Resources: 297,000 gold ounces (3.6 million tonnes at 2.59 gpt gold)
The Whiskey Jack zone, noted for being the highest-grade area within Grey Fox, holds:
- Indicated Resources: 122,000 gold ounces (735,000 tonnes at 5.16 gpt gold)
- Inferred Resources: 5,000 gold ounces (27,000 tonnes at 5.84 gpt gold)
Open Pit Mining Considerations
As part of the PFS, McEwen is exploring various scenarios for developing an open pit mining plan that aligns production timelines with initial capital requirements. The current 2025 Mineral Resource Estimate focuses on open pit resources accessible within the Company’s mineral claims, leaving room for expansion if agreements with adjacent landowners can be struck.
Stroud Project and Future Updates
Adjacent to Grey Fox, the Stroud Project was acquired by McEwen in 2024 and includes a historical resource estimate of approximately 270,000 gold ounces. Although this estimate does not conform to NI 43-101 guidelines and is considered non-current, the Company completed over 6,000 meters of drilling in 2025 to validate its potential. A new Mineral Resource Estimate for the Stroud Project is anticipated during the next Fox Complex resource update.
Additional Drilling and Future Outlook
Recent drill results underscore the potential for further growth at Grey Fox, with notable findings of 10.1 gpt gold over 5.8 meters among others. McEwen has allocated a budget of $5 to $10 million for drilling activities at Grey Fox in 2026, signaling ongoing commitment to resource exploration and enhancement.
