Collective Mining Reports High-Grade Intercept at Apollo, Announces 2026 Drill Program

Collective Mining Ltd. (NYSE: CNL) (TSX: CNL) announced October 29, 2025, that assay results from thirteen diamond drill holes at the Apollo system have returned a high-grade gold equivalent intercept and expanded the system’s western side. The company, which is focused on exploration projects in Caldas, Colombia, is also planning a substantial 2026 drill campaign.

The reported diamond drill holes targeted internal model gaps within the top 1,000 vertical meters of the Apollo system, which is part of the company’s Guayabales Project. Drilling on the western side of the Apollo system intersected high-grade mineralization, expanding that section by up to 50 meters.

Drill Hole Results and Western Expansion

Key intercepts include:

486.00 meters at 2.01 g/t gold equivalent from 54.10 meters downhole (APC-141).

144.30 meters at 2.08 g/t gold equivalent from 324.45 meters downhole (APC105-D5). This intercept is cited as the one that expanded the Apollo system westward by up to 50 meters at an elevation of 1,450 meters above sea level (MASL).

These results are expected to improve the internal block model grades, extend the mineralized volume, or upgrade confidence in the estimation.

Drill holes from Pad 30 cut mineralization beginning near surface, including:

APC-141: 486.00 meters at 2.01 g/t gold equivalent from 54.10 meters downhole.

APC-147: 84.55 meters at 2.04 g/t gold equivalent from surface.

Drill holes from mother hole APC-105D at Pad 18 extended the volume of the mineralized Apollo breccia body up to 50 meters horizontally and 140 meters vertically toward the southwest margin.

Ongoing Exploration and 2026 Plans

The company has completed approximately 142,000 meters of diamond drilling to date across the Guayabales and San Antonio projects, with 102,000 meters at Apollo. Numerous drill holes are awaiting assay results.

Ten drill rigs are currently operating across the company’s properties:

Guayabales Project: Six rigs are in operation. One rig is moving to conduct expansion drilling at the outcropping tungsten, gold, silver, and copper zone. Two rigs are performing infill drilling at Apollo (1,500 MASL to 1,000 MASL elevations). Two deep capacity rigs are focused on expanding the high-grade Ramp Zone at depth (below Apollo), and one rig has started drilling at Target X.

San Antonio Project: Four rigs are targeting the Pound zone, which has previously intersected a shallower zone of gold and silver-rich, intermediate sulphidation sheeted veins and a deeper gold-copper porphyry system.

Collective Mining is finalizing plans for an 80,000 to 100,000-meter drilling campaign in 2026 across the Guayabales and San Antonio projects. The company anticipates completing a maiden resource estimate for the Apollo system in the fourth quarter of 2026.
