Collective Mining Considerably Expands the Apollo Device to the North through as much as 450 Metres Via More than one Extensive Intercepts Representing a Unutilized Striking Wall Vein Zone

• Directional drilling from mom holes located smartly outdoor the identified breccia-hosted portion of Apollo all of a sudden intersected thick zones of strongly mineralized gold-rich sheeted veinlets. This unutilized zone, named the Striking Wall Vein Zone, approaches floor, extends the Apollo device as much as 450 metres northwards, and has been drilled as much as 600 metres vertically. Mineralization left-overs discoverable in all instructions.
• Spotlight intercepts into the Striking Wall Vein Zone come with:
  • 61.30 metres @ 1.78 g/t gold identical (APC-140D)
  • 130.40 metres @ 1.15 g/t gold identical (ACP-143D)
• The Corporate intends to aggressively drill the Striking Wall Vein Zone in Q1 2026, because it has sunny attainable, in response to perpetuity and width of mineralized zones, to materially building up the entire mineral stock of the Apollo device.
• As well as, the step-out drilling program has expanded the breccia mineralization through roughly 250 metres vertically and 55 metres laterally (Northern Growth Zone). Important intercepts come with:
  • 91.15 metres @ 2.31 g/t gold identical (APC106-D2)
  • 120.35 metres @ 1.35 g/t gold identical (APC106-D1)

TORONTO, Dec. 9, 2025 /PRNewswire/ – Collective Mining Ltd. (NYSE: CNL) (TSX: CNL) (“Collective” or the “Company”) is happy to announce assay effects for seven diamond drill holes that experience materially expanded the Apollo device (“Apollo”) northwards alongside collision through an supplementary 450 metres. Apollo is a large-scale, high-grade, in part Diminished Intrusion Indistinguishable Device enriched in gold, silver, copper and tungsten with mineralization traced from floor to over 1,370 vertical metres. Apollo anchors the Corporate’s flagship Guayabales Undertaking—a district-scale, multi-target and infrastructure-rich undertaking in Caldas, Colombia.

To day, Collective Mining has finished 153,000 metres of diamond drilling around the Guayabales and San Antonio initiatives, together with 106,500 metres at Apollo. With ten rigs actively working as a part of its absolutely funded program, the Corporate anticipates assay effects from a couple of high-priority holes within the alike time period.

With US$135 million in money (as of December 1, 2025), the Corporate is absolutely funded for its deliberate, competitive 2026 program, which goals as much as 100,000 metres of supplementary drilling.

Ari Sussman, Government Chairman, commented: “It’s time to reframe our view of Apollo—not merely as a mineralized breccia system, but as a much larger entity encompassing the breccia body and surrounding sheeted vein zones with the potential to extend strike lengths by hundreds of meters. Most exciting is the serendipitous discovery of mineralization in the Hanging Wall Vein Zone during directional drilling of mother holes, which were intended solely to establish kick-off points for testing the high-grade Ramp Zone at depth. With targeted drilling now planned for the Hanging Wall Zone in 2026, I’m optimistic this will usher in a new era of significant resource expansion at Apollo.”

Striking Wall Vein Zone Discovery

Two mom holes, drilled to lend kick-off issues for drill checking out the Ramp Zone, came upon a big unutilized zone of sheeted, gold-and silver-rich veinlets within the striking wall to the identified Apollo device.

Assay intersections from the Striking Wall Vein Zone come with:

APC-140D (drilled south from Dwelling 29):

• 61.30 metres @ 1.78 g/t gold identical from 503.70 metres 
  → together with 13.25 metres @ 4.47 g/t gold identical from 503.70 metres
• 24.95 metres @ 1.99 g/t gold identical from 636.50 metres 
  → together with 5.60 metres @ 4.60 g/t gold identical from 639.30 metres 
  → and together with 4.25 metres @ 3.72 g/t gold identical from 657.20 metres

APC-143D (drilled southwest from Dwelling 19):

• 10.00 metres @ 5.74 g/t gold identical from 433.50 metres
• 130.40 metres @ 1.15 g/t gold identical from 622.40 metres
  → together with 5.35 metres @ 3.65 g/t gold identical from 659.90 metres
  → and together with 12.25 metres @ 3.27 g/t gold identical from 674.40 metres

This newly came upon Striking Wall Vein Zone has expanded the mineralized footprint at Apollo. The interpreted northeast collision area has higher through 43%, with the device now measuring roughly 1,050 metres (prior to now 600 metres) × 400 metres width × 1,370 metres vertical extent. Apollo left-overs totally discoverable alongside collision to the north and at intensity.

The Corporate plans an competitive follow-up drilling marketing campaign focused on the Striking Wall Vein Zone starting off early Q1 2026 to impulsively make bigger and delineate this thrilling unutilized discovery.

Apollo Breccia Continues to Develop – Unutilized Northern Extension Showed as much as 900 Meters Under Floor

4 drill holes from Dwelling 19 and Dwelling 29 have effectively prolonged the Apollo breccia device from 120 meters to 175 meters alongside collision to the northeast and 250 metres deeper than prior to now intersected in hollow APC100-D1 (see press shed dated December 4, 2024). Those holes ascertain perpetuity of the high-grade breccia mineralization as much as roughly 900 metres underneath floor in the neighborhood on its northern flank the place it left-overs discoverable at intensity for additional enlargement. Highlights from the Northern Growth Zone come with: 

APC106-D1 (drilled to the southwest)

• 120.35 metres @ 1.35 g/t gold identical from 138.00 metres
  → together with 11.65 metres @ 2.25 g/t gold identical from 178.20 metres  
  → 29.20 metres @ 2.24 g/t gold identical from 229.15 metres 
  → and 17.70 metres @ 3.03 g/t gold identical from 319.00 metres 

APC106-D2 (drilled to the southwest)

• 91.15 metres @ 2.31 g/t gold identical from 302.85 metres  
  → together with 18.20 metres @ 6.31 g/t gold identical from 341.50 metres (one of the crucial highest-grade divisions intersected to day at this intensity and on this location) 

APC143-D1 (drilled to the southwest)

• 111.20 metres @ 1.34 g/t gold identical from 48.55 metres  
  → together with 14.00 metres @ 3.12 g/t gold identical from 130.00 metres 

APC140-D1 (drilled to the southwest)

• 15.10 metres @ 1.70 g/t gold identical from 197.40 metres
