Collective Mining Reports Robust Metallurgical Recovery Rates at Apollo: 95% Gold, 92% Silver, 85% Copper and 70% Tungsten; Initial Mineral Resource Estimate Targeted for September 2026 - PR Newswire Canada

• Advanced metallurgical test work from a master composite representative of approximately the top 1,000 meters of the Apollo system, generated strong recovery rates across gold, silver, copper, and tungsten using conventional processing methods
• A significant portion of the gold at Apollo is amenable to gravity recovery, with certain tests yielding greater than 50% of the total gold reporting to gravity concentrates
• Preliminary metallurgical test results on material from the Apollo System's high-grade Ramp Zone at depth, have recovered up to 96% of the gold using only conventional processing options; a comprehensive program is underway with results expected in H1-2027
• The Company has significantly accelerated its internal timeline to apply for a license for the project and as a result now expects to release its maiden mineral resource estimate on Apollo in September 2026
