Collective Mining Reports Significant Gold Assay Results in Ramp Zone

Collective Mining Ltd (NYSE: CNL, TSX: CNL FSE: GG1). has reported significant assay results from two follow-up drill holes in the recently identified Ramp Zone within its Apollo system, part of the Guayabales Project in Caldas, Colombia. Drill hole APC103-D2 intersected 51.95 meters grading 8.38 grams per tonne (g/t) gold equivalent (AuEq), including an 18.05-meter segment at 16.32 g/t AuEq. This represents the deepest mineralization encountered at Apollo, reaching approximately 1,200 meters below the surface.

The Ramp Zone discovery shares characteristics with reduced or partially reduced intrusion-related systems, similar to Aris Mining’s Marmato Deeps gold deposit, located 1.75 kilometers southeast. The Marmato Deeps deposit hosts a National Instrument 43-101 compliant resource estimate of 3.76 million ounces of gold in the measured and indicated category at 2.54 g/t gold and 2.54 million ounces of inferred gold at 2.39 g/t gold.

Drilling efforts are ongoing in the Ramp Zone, with two holes in progress and a third drill pad under construction. The zone remains open in all directions for potential expansion. Collective Mining’s 2025 drilling program includes up to three rigs targeting the Ramp Zone as part of a fully funded 60,000-meter campaign. The company has also contracted two additional rigs, with drilling commencing in February.

The Ramp Zone mineralization is between 1,050 and 1,200 meters below the surface. Gold and silver mineralization is associated with sulfides of bismuth and tellurium, along with pyrite and pyrrhotite in veins and stockwork. The company has dispatched samples for microscopic evaluation to better understand the genesis of the Ramp Zone.

Collective Mining Ltd. is a gold, silver, copper, and tungsten exploration company with projects in Caldas, Colombia. The company’s flagship project, Guayabales, is anchored by the Apollo system, which hosts large-scale, bulk-tonnage, and high-grade mineralization.
