Monitor for the next phase of metallurgical work including locked-cycle testing of higher-grade copper sub-domain material and variability testing, as well as progress toward the planned 2027 licensing submission in Colombia. The additional 42,000 metres of drilling not yet included in the Mineral Resource could lead to resource expansion updates.

Executive Summary
Collective Mining reported strong metallurgical test results for its Apollo deposit, demonstrating high recoveries for gold, silver, copper, and tungsten using conventional processing methods. The company is advancing an integrated dual-route flowsheet toward a planned 2027 licensing submission in Colombia, with new copper and tungsten sub-domain test results showing 95% copper recovery and up to 74% tungsten recovery.
Key Facts
- Apollo master composite locked-cycle testing showed 95% gold, 92% silver, and 85% copper recovery with low cyanide consumption of 0.57 kg/t
- Copper sub-domain open-circuit testing showed 95% copper, 90% gold, and 94.4% silver recovery producing a concentrate grading 27.2% Cu, 37.6 g/t Au, and 3,504 g/t Ag
- Tungsten sub-domain test work showed tungsten recovery through gravity and flotation of up to 74%, with bulk-sample testing producing a concentrate containing 95% scheelite
- Copper Sub-Domain contains 10.2 Mt Indicated grading 0.41% Cu, representing 27.6% of total Indicated Mineral Resource
- Tungsten Sub-Domain contains 2.57 Mt Indicated grading 0.10% WO3, representing 6.9% of total Indicated Mineral Resource
- Over 42,000 metres of additional drilling completed at Apollo since the March 31, 2026 Mineral Resource database cut-off is not included in the current Mineral Resource
- Management, insiders, a strategic investor and close family and friends own 45.2% of the Company's outstanding shares
Financial Impact
No financial figures or deal values provided; pre-revenue exploration stage company
Risk Factors
- Pre-revenue exploration stage with no demonstrated economic viability; Mineral Resources are not Mineral Reserves
- Forward-looking statements subject to risks including speculative nature of business, variations in mineralization, grade or recovery rates, and regulatory approvals in Colombia
- The Copper and Tungsten Sub-Domains are not mutually exclusive and may overlap, potentially leading to double-counting if aggregated
