Highlights 

  • Collective Mining expands the Apollo system up to 450 metres north with the discovery of the new Hanging Wall Vein Zone. 
  • Directional drilling reveals broad gold-rich veinlet zones approaching the surface and open in all directions. 
  • Step-out drilling extends breccia mineralization 250 metres deeper and 55 metres laterally in the Northern Expansion Zone. 

Collective Mining Ltd. (TSX:CNL) has delivered one of its most significant updates to date, announcing a major expansion of its Apollo system following the discovery of a new mineralized zone—the Hanging Wall Vein Zone—identified through directional drilling. The results materially extend Apollo’s footprint and further strengthen the Guayabales Project in Caldas, Colombia. 

New Hanging Wall Vein Zone Extends Apollo Up to 450 Metres North 

The discovery came from two mother holes drilled outside the known breccia-hosted portion of Apollo. These holes unexpectedly intercepted broad intervals of gold-rich sheeted veinlets, marking the identification of the Hanging Wall Vein Zone. 

Key intercepts include: 

  • 61.30m @ 1.78 g/t AuEq (APC-140D) 
  • 130.40m @ 1.15 g/t AuEq (APC-143D) 

High-grade sections within these intervals returned values of up to 5.74 g/t AuEq over 10m and 4.47 g/t AuEq over 13.25m. 

The newly defined zone: 

  • approaches surface, 
  • extends the Apollo system’s strike length by up to 450 metres north, 
  • has been drilled to a vertical depth of 600 metres, and 
  • remains fully open in all directions. 

As a result, Apollo’s interpreted strike length has increased by 43%, now spanning approximately 1,050 metres × 400 metres × 1,370 metres vertically. 

Collective plans an aggressive follow-up program in Q1 2026 specifically targeting the Hanging Wall Vein Zone, given its potential to materially lift the mineral inventory. 

Breccia Body Also Expands: Up to 250 Metres Deeper 

In addition to the new vein zone, step-out drilling from Pads 19 and 29 has extended the breccia body—known for its high-grade bulk-tonnage potential—both laterally and at depth: 

Notable intercepts from the Northern Expansion Zone include: 

  • 91.15m @ 2.31 g/t AuEq (APC106-D2) 
  • 120.35m @ 1.35 g/t AuEq (APC106-D1) 
  • 111.20m @ 1.34 g/t AuEq (APC143-D1) 

The breccia system now reaches depths of up to 900 metres below surface on its northern flank and remains open for further extension. 

A Fully Funded, High-Momentum Program for 2026 

Collective Mining has now completed 153,000 metres of drilling across Guayabales and San Antonio, including 106,500 metres at Apollo. With ten active rigs and USD 135 million in cash, the company is well funded to advance its largest program to date, targeting up to 100,000 metres of drilling in 2026. 

Executive Chairman Ari Sussman emphasized that Apollo should now be viewed as a much larger mineralized system combining breccia and vein zones, stating that the new discovery could usher in “a new era of significant resource expansion.”
