Collective Mining Significantly Expands the Apollo System to the North by up to 450 Metres Through Multiple Broad Intercepts Representing a New Hanging Wall Vein Zone
Collective Hits Again, Expands Apollo North in Serendipitous Discovery
On December 9, 2025, Collective Mining announced a significant expansion of its Apollo porphyry system at the Guayabales project in Colombia. Drilling has extended the system up to 450 metres to the north, well beyond the previously understood footprint.
Key highlights from the release include: - Northern Expansion: Multiple broad intercepts have expanded the strike length of the Apollo system from ~600 metres to ~1,050 metres. The overall dimensions are now stated as approximately 1,050m strike x 400m width x 1,370m vertical extent. - New Discovery: A new "Hanging Wall Vein Zone" was discovered serendipitously while drilling mother holes for deeper targets. This zone returned significant intercepts, including 130.4 metres @ 1.01 g/t AuEq and 61.3 metres @ 1.58 g/t AuEq. - Strong Intercepts: Other notable intercepts in the northern expansion zone include 120.35 metres @ 1.26 g/t AuEq, 91.15 metres @ 2.13 g/t AuEq, and 111.2 metres @ 1.28 g/t AuEq. - Future Plans: The company plans an aggressive 100,000-metre drill program for 2026 to further delineate the expanded system. - Financial Position: The company reports a strong cash position of US$135 million.
Executive Chairman Ari Sussman noted that the view of Apollo should be reframed as a much larger entity encompassing the main breccia body and surrounding vein zones, highlighting the potential for significant resource expansion.
This news is materially positive and represents a significant de-risking event and a step-change in the potential scale of the Apollo project. While the company has consistently delivered strong exploration results, this announcement stands out for two key reasons:
- Scale of Expansion: A 450-metre step-out to the north is a massive extension, nearly doubling the previously known strike length. This is not an incremental infill result but a major expansion that significantly increases the mineralized footprint and tonnage potential of the system.
- Discovery of a New Zone: The identification of the Hanging Wall Vein Zone was unexpected. Discovering a new style of mineralization while targeting another demonstrates the robustness and fertility of the overall mineralizing system. It opens up a completely new target area for resource growth that was not previously contemplated.
This release builds upon a sequence of positive updates. After expanding the deeper, high-grade Ramp Zone on December 3, this news now demonstrates significant expansion potential in a different direction and at shallower depths. The grades reported are consistent with a bulk-tonnage deposit and are economically significant over the broad widths intersected. The market should react positively as this fundamentally increases the scope of what a future mining operation at Apollo could look like, reinforcing the view that Apollo is a Tier-1 discovery.
The announcement aligns with the company's stated goal of demonstrating the multi-million-ounce potential of the system ahead of a maiden resource estimate planned for the end of 2026. With US$135 million in cash, the company is fully funded to execute its aggressive follow-up drilling.
Collective Mining Ltd. is a Canadian-based mineral exploration company focused on its projects in the Caldas department of Colombia, a historically mining-friendly region. The company was founded by the team that successfully developed and sold Continental Gold to Zijin Mining.
The company's flagship asset is the 100%-owned Guayabales Project, which hosts the Apollo discovery. Apollo is a large-scale, bulk-tonnage gold-silver-copper-tungsten porphyry system that remains open for expansion. The exploration strategy is focused on expanding the overall footprint of Apollo, defining near-surface mineralization, and chasing high-grade zones at depth, such as the "Ramp Zone." The company also holds the nearby San Antonio project, where it is exploring for a large gold-copper porphyry system.
