Recent Discovery at Froome Mine Continues to Expand Along Strike and Down-Dip;
Drilling at Depth Shows Potential to Extend Mine Life
7.7 gpt gold over 20.4 meters & 23.5 gpt gold over 3.7 meters
(results above are true widths)
TORONTO, December 4, 2025 (GLOBE NEWSWIRE) -- McEwen Inc. (NYSE/TSX: MUX) is pleased to
announce new drill results from its Froome Mine, part of the Fox Complex in Timmins, Ontario ( Figure 1).
Based on our confidence in the geological potential, four drills are now active at Froome West, targeting further
expansion of these excellent results.
Why These Drill Results Are Important to Our Investors
1. Significant Extension of High-Grade Mineralization
• Extended the higher-grade gold mineralization by 100 meters vertically , representing a 45%
increase since our last update in July 2025.
2. Potential to Extend Froome’s Mine Life and Improve Economics
• Greater mining flexibility, enabling higher production and lower costs.
• Mill feed from multiple sources from H2 2026, including the Stock Mine currently under
development.
• Continued exploration success could enable concurrent mining at Froome and Stock, supporting
a meaningful extension of operations.
Unless specified as core widths (CW), all assay intervals in this press release are presented as true widths (TW).
Froome West Drill Highlights
a) Some of the deepest intersections to date confirm that gold mineralization remains open at depth ,
providing confidence that additional resources exist below the currently planned limit of the mine. Follow-up
drilling around these results aim to extend the mineralization and mine life at Froome (Figure 2).
• Drillhole 25PR-G475 returned 23.5 gpt gold over 3.7 meters and 11.5 gpt gold over 1.6 meters.
• Drillhole 25PR-G487 returned 4.6 gpt gold over 8.1 meters.

b) Gold mineralization was extended up to 50 meters West , potentially increasing the number of defined
ounces per vertical meter, an important metric in lowering future production and development costs per
ounce (Figure 2).
• Drillhole 25PR-G454 returned 7.9 gpt gold over 6.4 meters.
• Drillhole 25PR-G457 returned 7.5 gpt gold over 4.4 meters.
c) Drilling near recently completed underground infrastructure returned highly promising grades as
seen below ( Figure 2 ). Due to their proximity to existing underground development, the Company
anticipates mining these areas during H1 2026.
• Drillhole 25PR-G478 returned 6.1 gpt gold over 10.4 meters.
• Drillhole 25PR-G467 returned 7.7 gpt gold over 20.4 meters.

Next Steps at Froome
Surface diamond drilling will continue into Q1 2026 to further define the mineralization that remains open to
the West and at depth.
Underground access on four separate levels has been established in the upper portion of Froome West, and
mining has commenced. Three deeper levels are under dev elopment to access mineralization defined by the
recent drilling (Figures 2 to 4).
McEwen plans to publish an updated resource estimate for Froome West at the end of February 2026.

alignments, is available on the Company’s website and can be accessed by clicking here.
