At the Guayabales Project, Apollo hosts a maiden Mineral Resource of 2.58 million ounces AuEq Indicated and 2.83 million ounces AuEq Inferred. Collective states that its resource information under NI 43-101 and the CIM Definition Standards may not be comparable with disclosures by U.S. companies under S-K 1300.
Collective Mining Ltd. (CNL) reported strong metallurgical results and an integrated dual-route processing flowsheet for the Apollo deposit at its Guayabales Project in Colombia, supporting a planned 2027 licensing submission. Locked-cycle tests on an Apollo master composite achieved 95% gold, 92% silver, and 85% copper recovery with low cyanide consumption of 0.57 kg/t. Copper sub-domain tests recovered 95% copper, 90% gold and 94.4% silver, producing a concentrate grading 27.2% Cu, 37.6 g/t Au and 3,504 g/t Ag, while tungsten test work achieved up to 74% tungsten recovery and a concentrate containing 95% scheelite. Apollo’s maiden Mineral Resource totals 37.0 Mt Indicated at 2.17 g/t AuEq (2.58 Moz AuEq, 1.64 Moz Au) and 48.2 Mt Inferred at 1.83 g/t AuEq (2.83 Moz AuEq, 2.47 Moz Au), with meaningful copper and tungsten by-products. Management, insiders and related parties hold 45.2% of outstanding shares.
Collective Mining Ltd. (CNL) reports new drill results from the Apollo Deposit at its Guayabales Project, focusing on the Shallow Halo Zone (SHZ) and infill of the existing Mineral Resource model. A key intercept in the SHZ is 135.15 meters at 2.12 g/t AuEq from 21.30 meters in hole APC-182, including 61.05 meters at 3.65 g/t AuEq within the transition zone. Additional shallow intercepts from northern, western and southeastern portions of the SHZ suggest mineralization in oxide, transition and primary rock where the current open pit model had previously been treated as waste.
The company states that only about 20% of the interpreted 2.4 km by 200 m SHZ has been drill tested and three rigs are dedicated to the remaining 80%. A separate intercept of 52.10 meters at 0.33 g/t AuEq in hole APC-164D, located approximately 120 meters northeast of the existing pit outline, indicates potential for extending the SHZ beyond the current shell. Across the broader Apollo system, Collective has completed 129,500 meters of drilling at Apollo (193,500 meters including other projects) and has a maiden Mineral Resource of 2.58 million ounces AuEq indicated and 2.83 million ounces AuEq inferred. With US$93.7 million in cash as of June 30, 2026 and up to 90,000 meters of drilling planned for 2026, the company highlights strong funding for continued expansion and infill work.
Collective Mining Ltd. (CNL) reports a maiden Mineral Resource for the Apollo deposit at its Guayabales Project in Caldas, Colombia, establishing a multi-commodity gold-silver-copper-tungsten system. The estimate, effective August 31, 2026, is based on approximately 114,520 meters of diamond drilling in 265 holes, with a database cut-off of March 31, 2026.
The Apollo Mineral Resource totals 2.58 million ounces AuEq Indicated (37.0 Mt at 2.17 g/t AuEq) and 2.83 million ounces AuEq Inferred (48.2 Mt at 1.83 g/t AuEq), including contained 1.64 Moz gold and 2.47 Moz gold in the Indicated and Inferred categories respectively. Metal recoveries used in the model are supported by metallurgical test work showing locked-cycle recoveries of 95% gold, 92% silver, 85% copper and up to 74% tungsten, indicating amenability to conventional processing.
The system remains open in several directions and about 40,000 meters of additional drilling completed after the cut-off are not yet included, with an updated Mineral Resource targeted for Q1 2028. Planned milestones, all subject to study results, financing and approvals, include commencing an underground exploration adit in Q4 2026, submitting an environmental license application in H2 2027, publishing a preliminary economic assessment in H2 2028 and a feasibility study by mid-2029.
