Collective Mining Ltd. reported that seven new diamond drill holes have extended the Apollo system northward by up to 450 m, adding a previously unknown hanging‑wall vein zone to the existing breccia body. The new intercepts contain broad gold‑ and silver‑rich veinlets.

The expansion increases the system’s strike length by roughly 43 %, raising the interpreted northeast strike length from about 600 m to 1,050 m. The discovery confirms that mineralization continues to the north and at depth, reinforcing the district‑scale potential of the Guayabales project.

The new vein zone provides additional targets for the 2026 drilling program, which the company plans to execute aggressively in Q1 2026. Management stated that the company is fully funded for a 100,000‑meter program, positioning it to accelerate a maiden resource estimate and enhance the strategic value of the Apollo system for future development or sale.

Collective Mining’s cash position stood at $135 million as of December 1, 2025, and the company has completed 153,000 m of diamond drilling across Guayabales and San Antonio, with 106,500 m at Apollo. The experienced management team, formerly of Continental Gold, brings a proven track record in Colombian exploration.

The discovery of the hanging‑wall vein zone is a key milestone that expands the known mineralized footprint and supports the company’s strategy to define a high‑grade, district‑scale resource. The expansion also strengthens Collective Mining’s competitive position in Colombia’s underexplored mining landscape.
