[{"type":"text","content":"Liberty Gold Reports Strong Phase 5A Column Leach Metallurgical Results at Black Pine, Confirming Consistent Oxide Gold Recoveries Across Newly Tested Zones80.6% weighted average gold extraction from 24 column leach tests\n\n\n\n VANCOUVER, British Columbia, Aug. 19, 2025 (GLOBE NEWSWIRE) -- Liberty Gold Corp. (TSX: LGD; OTCQX: LGDTF) (“Liberty Gold” or the “Company”) is pleased to report results from its Phase 5A metallurgical program at the Company’s Black Pine Oxide Gold Project (“Black Pine”) in southeast Idaho. The new results confirm consistent, robust gold recoveries across previously untested areas, supporting the feasibility development of a run-of-mine (“ROM”) heap leach processing flowsheet at Black Pine.\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 80.6%\n \n , with individual composites reaching up to\n \n 90.8%\n \n , demonstrating metallurgical continuity across multiple mineralized zones; all of the Phase 5A composites tested exhibit the typical Black Pine leach result of greater than 80% of the eventual gold extraction achieved in under 10 days.\n \n\n\n Corroborated Bottle Roll Data:\n \n Gold and silver extractions from coarse crush bottle roll tests strongly correlate with column leach results, 78.9% vs 80.6%, respectively, in line with previous metallurgical results.\n \n\n\n De-risking Project Development:\n \n Phase 5A column tests reinforce the suitability of ROM heap leach processing and provide key inputs into the ongoing feasibility study metallurgical model.\n \n\n\n Expanded Metallurgical Coverage:\n \n Phase 5A testing included composites from Back Range and J Zone, areas not previously tested and variability composites infilling previous sampling in the M Zone, Tallman and F zones.\n \n\n\n Ongoing Programs:\n \n Phase 5B (additional variability infill composites) results are expected in Q3, 2025, Phase 7 (cut-off-grade (“COG”) composites) results expected in Q4, 2025 and Phase 6 (bulk samples) and Phase 8 (legacy heap facility (“HLF”) sonic drilling composites) expected in early H1, 2026.\n \n\n\n\n\n Jon Gilligan, President and CEO, Liberty Gold, commented, “\n \n These results further demonstrate that B...
