(TSX: LGD; OTCQX: LGDTF) (“Liberty Gold” or the “Company”) is pleased to report results from its Phase 5B metallurgical program at the Company’s Black Pine Oxide Gold Project (“Black Pine”) in southeast Idaho. The new results confirm consistent, predictable gold recoveries across the primary ore bodies at Black Pine, further supporting a low cost, run-of-mine (“ROM”) heap leach processing flowsheet.\n \n\n\n Highlights\n \n\n\n\n\n Consistent Gold Extractions and Leach Performance:\n \n Weighted average column leach gold extraction of\n \n 81.9%\n \n at an average head grade of 0.65 parts per million (“ppm”) gold (“Au”), with individual composites ranging from 52% to 94.5%. Phase 5B composites exhibit the typical Black Pine leach result of greater than 80% of the eventual gold extraction achieved in under 10 days.\n \n\n The feasibility recovery model has been updated with these new results and shows gold recoveries in line or slightly better than previous results across Rangefront and Discovery Zones.\n \n\n\n\n\n Corroborated Bottle Roll Data:\n \n Gold extractions from direct leach coarse crush bottle rolls (P\n \n 80\n \n of 1.68 millimeters (“mm”)) are aligned with column leach results (P\n \n 80\n \n of 16.9mm) at 78.4% vs 81.9%, respectively.\n \n\n This relationship further validates that gold leaching at Back Pine is highly insensitive to crush size.\n \n\n\n\n\n Confirmation of Recovery in Primary Mining Phases:\n \n Phase 5B testing focused on infill sampling within the primary mining phases of Rangefront and Discovery Zones.\n \n\n Feasibility level metallurgical work will be completed in H1, 2026. It is anticipated that with resource growth at Rangefront, additional test work may be required to achieve variability coverage.\n \n\n\n\n\n See\n \n https://vrify.com/decks/20140\n \n for a dynamic 3D view of the composite sample locations from the comprehensive metallurgical program across the Black Pine ...
