Omai Gold Drills 3.08 g/t Au over 25.8m, 6.84 g/t Au over 9.5m, and 1.52 g/t Au over 37.5m at Wenot Deposit; Provides Update on Deep Hole Beneath Wenot Deposit

Executive Summary

• Omai Gold released assay results for six new drill holes (25ODD‑122, 124‑127, 128) on the Wenot deposit, adding significant high‑grade intercepts that will feed into an updated Preliminary Economic Assessment expected in early Q1 2026.
• Highlights include 17.06 g/t Au over 3.1 m (hole 25ODD‑127), 27.51 g/t Au over 1.2 m (hole 25ODD‑125), and multiple >10 g/t Au intervals, underscoring the deposit’s high‑grade potential at depth.
• The company is continuing deep drilling (hole 25ODD‑122 now at 1,860 m downhole) and expanding exploration to satellite targets (Camp Zone, Blueberry Hill), with assays pending, indicating further upside for resource growth.

Key Details

• Drill Program Scope: 43 holes drilled in 2025 totaling 23,500 m; six new Wenot holes reported here (total 3,782 m).
• Hole 25ODD‑127: 3.08 g/t Au over 25.8 m; includes 17.06 g/t Au over 3.1 m and 7.33 g/t Au over 1.5 m.
• Hole 25ODD‑125: 6.84 g/t Au over 9.5 m; includes 27.51 g/t Au over 1.2 m and 9.80 g/t Au over 1.5 m.
• Hole 25ODD‑126: Multiple intervals – 5.39 g/t Au over 3.4 m, 2.08 g/t Au over 18 m, 1.31 g/t Au over 39.5 m, plus high‑grade narrow shoots (10.93 g/t Au over 1.5 m).
• Hole 25ODD‑117: 10.16 g/t Au over 2.6 m; also 4.53 g/t Au over 2.4 m and 1.98 g/t Au over 7.5 m.
• Deep Hole 25ODD‑122: Reached 1,860 m downhole; intersected Wenot shear corridor at 1,598 m depth, continuing for ~267 m with sampling underway. Potential to significantly extend resource at depth.
• Exploration Targets:
• Camp Zone – five holes completed, assays pending; near‑surface satellite potential west of Wenot.
• Blueberry Hill Trend – six holes completed; historic high‑grade intersections suggest additional mill‑feed source.
• Future Work: Additional drilling planned to increase density in Central Quartz‑Feldspar Porphyry (CQFP) and Dike Corridor, aiming to upgrade inferred resources to indicated and reduce strip ratio for the upcoming PEA.
• CEO Comment: Elaine Ellingham highlighted that the new results will feed into an updated PEA expected early Q1 2026 and noted the significance of deep blue‑sky potential for extending mine life.
