Orla Mining Discovers Potential Two-Kilometre Extension at Musselwhite

Executive Summary

• Deep directional drilling at Musselwhite intersected a high‑grade gold zone extending ~1.6 km along strike, including a standout intercept of 4.1 m @ 15.1 g/t Au with visible gold and multiple higher‑grade sub‑intervals (>20 g/t Au).
• Underground drilling returned several significant high‑grade intersections (e.g., 10.1 m @ 27.2 g/t Au, 15.7 m @ 6.89 g/t Au) supporting resource replacement and potential expansion.
• Near‑mine surface programs identified multiple satellite targets within a 10 km radius, with notable intercepts such as 2.7 m @ 2.59 g/t Au (Camp Bay) and 14.7 m @ 0.74 g/t Au (Camp Bay), indicating open‑pit potential.

• Program Status
• Deep directional program ~65 % complete (8,000 m of 11,000 m drilled); remaining daughter holes to be completed by year‑end 2025 with assay results expected Q4 2025/Q1 2026.
• Underground drilling: 19,100 m across 76 holes; assays received for 37 holes.
• Near‑mine surface program: 5,500 m drilled to date; further holes deferred to winter 2026.
• Strategic Implications
• Extension of the Mine Trend up to ~2 km beyond current resources could substantially increase reserve life and annual gold production.
• High‑grade underground intercepts support ongoing resource replacement and potential upside in proven & probable reserves (currently 892 koz Proven, 635 koz Probable).
• Satellite target work may enable future open‑pit feed sources, diversifying the mine’s ore base.

Notable Quotes

• “These results validate our investment thesis for Musselwhite – this is a rare, high‑quality asset with the geological continuity to support decades of additional production.” – Sylvain Guerard, SVP Exploration, Orla Mining Ltd.
