New High-Grade Gold Zone at Windfall Project

Executive Summary

• McEwen Inc. reported a new high‑grade gold–silver–base metal zone from drill hole WF033, including 8.1 g/t Au over 8.7 m and an exceptional sub‑interval of 50.3 g/t Au with 782 g/t Ag, 15% Pb and 2.5% Zn over 1.3 m (62.5 g/t Au‑eq).
• Additional notable intercepts were returned from holes WF032–WF030, ranging from 1.2 to 2.0 g/t Au over lengths of 10–38 m.
• The discovery confirms continuous mineralization in the Windfall Fault Zone and introduces a previously unknown fault zone with CRD‑style high‑grade mineralization, potentially accelerating permitting because the area sits on private (patented) land.

Key Details

• WF033 – New High‑Grade Zone: 8.1 g/t Au over 8.7 m; within this, 50.3 g/t Au, 782 g/t Ag, 15% Pb, 2.5% Zn over 1.3 m (62.5 g/t Au‑eq).
• Other Intercepts:
• WF032 – 2.0 g/t Au over 38.3 m.
• WF031 – 1.2 g/t Au over 17.1 m.
• WF030 – 1.2 g/t Au over 10.1 m.
• Assay Highlights (Appendix): Detailed assay tables confirm the above grades and provide CN‑ratio metallurgical data (e.g., 93.7% cyanide recovery for the 8.08 g/t Au interval).
• Geological Setting: High‑grade mineralization hosted in the Windfall Fault Zone; newly discovered fault 50 m east shows CRD‑style carbonate replacement deposit mineralization, suggesting strong potential for further high‑grade discoveries.
• Metallurgical & Permitting Notes: PQ‑size holes drilled for metallurgical testing show favorable cyanide leach recoveries (>60%). Private land status may shorten permitting timelines.
• Next Steps (2025 Drilling Goals): Publish a resource estimate by year‑end; test extensions at depth and along strike; collect samples for metallurgical testing; explore new nearby targets.
