Insights

Mining Geologist and Resource Estimation Expert

Collective Mining's drilling extends high-grade Ramp Zone 200m along strike with impressive gold-silver results, significantly enhancing Apollo's resource potential.

The latest drill results from Collective Mining's Ramp Zone represent a substantial exploration success that materially expands the potential resource envelope at the Apollo system. The two reported holes delivered impressive intercepts: 50.50 metres at 5.66 g/t gold and 13 g/t silver in one hole and 70 metres at 2.00 g/t gold and 5 g/t silver in the second, deeper hole.

What makes these results particularly significant is the 200-metre strike extension to the east, coupled with confirmation that the system remains open in all directions. The Ramp Zone has now been defined across 275 metres of strike by 200 metres vertical, and the total Apollo system has been traced over an impressive 1,300 vertical metres from surface.

The geological characteristics described—reduced intrusion related gold system with sulphide mineral assemblages—suggest a robust mineralization system with strong similarities to Aris Mining's nearby Marmato Deeps deposit. The key differentiator appears to be the higher grades encountered at the Ramp Zone, attributed to two factors: the breccia host rock providing better porosity for metal deposition and the overprinting by high-grade porphyry veins.

The acquisition of additional surface and mineral rights is a strategic move that secures both infrastructure potential and the entirety of the Apollo system, eliminating potential future complications in project development. The US$70.6 million treasury position provides ample funding for the aggressive 70,000 metre drill program planned for 2025.

The comparison to the nearby Marmato Deeps deposit (with its 3.76 million ounces measured and indicated plus 2.54 million ounces inferred) provides a compelling analog for the potential scale of the Ramp Zone, especially considering the Ramp Zone's higher grades thus far. The continued expansion of this zone with two dedicated rigs could substantially increase the overall resource potential of the Apollo system in the near term.

• Two new holes have tested the high-grade Ramp Zone by intersecting wide and continuous intervals of reduced intrusion related gold mineralization. The Ramp Zone locates at the bottom of the Apollo system.
  
  
• APC103-D6, which was the shallower and first of the two new holes to intercept the Ramp Zone, cut 50.50 metres at 5.66 g/t gold and 13 g/t silver and extended the system laterally by approximately 50 metres to the northeast.
  
  
• APC106-D2, which is the deepest hole drilled to date into the Ramp Zone, cut 70 metres at 2.00 g/t gold and 5 g/t silver.
  
  
• Hole APC106-D2 has extended the Ramp Zone deeper and along strike by approximately 200 metres to the east. The Ramp Zone has now been defined through localized drilling over an area measuring 275 metres of strike by 200 metres vertical and remains open in all directions. As a result, the total vertical dimension of the Apollo system has been traced from surface over 1,300 metres (800MASL) and remains open at depth for further growth.
  
  
• Two new large capacity rigs are currently drilling the Ramp Zone with the first directional hole (APC-140D1) cutting potentially favorable Ramp Zone mineralization and the second rig about to begin its first directed hole towards the target. The intent of the current program is to extend the Ramp Zone at least another 200 metres vertically and laterally along strike.

TORONTO, Oct. 1, 2025 /PRNewswire/ - Collective Mining Ltd. (NYSE: CNL) (TSX: CNL) ("Collective" or the "Company") is pleased to announce assay results for two diamond drill holes designed to continue expanding the high-grade Ramp Zone, which is located at the bottom of the Apollo system ("Apollo"). Apollo, which begins at surface, is strongly mineralized over 1,300 vertical metres and is open at depth. It is the most advanced discovery made to date within the Company's multi-target, Guayabales Project in Caldas, Colombia.

The Company, which remains well funded with approximately US$70.6 million in its treasury as of the end of Q2 2025, currently has ten drill rigs turning as part of its fully funded 70,000 metre drill program for 2025. Seven of the rigs are operating at the Guayabales Project and three rigs are drilling at the San Antonio Project. Drilling at the Guayabales Project is focused on multiple objectives relating to the Apollo system which includes expanding the high-grade Ramp Zone ("Ramp") (located at the bottom of Apollo) at depth and along strike as well as testing new targets across the project area.

Approximately 137,000 metres of diamond drilling has been completed to date at the Guayabales Project, including 97,000 metres at Apollo. There are currently sixteen drill holes in the lab with assay results for most of these holes expected in the near term.

Ari Sussman, Executive Chairman commented: "It's been a long wait for the arrival of the deeper capacity rigs but our expansion drilling of the Ramp Zone is now taking flight. We are highly encouraged by the results today and are optimistic that drilling will continue to validate our thesis that the Ramp Zone could have dimensions similar to Aris Mining's multi-million-ounce Marmato Deeps deposit, located only 1.75 kilometres to the southeast and currently being constructed with production scheduled for 2026. We are looking forward to an exciting finish to this year with expansion drilling underway at the Ramp Zone (Guayabales Project) and an aggressive drill program at our San Antonio Project."

Details (see Table 1-2 and Figures 1-4)

Hole APC103-D6 was drilled as a wedge hole from mother hole APC-103D at Pad 16 in a southwest direction and intersected the Ramp Zone 50 metres to the east from previous drill holes APC103-D1 and APC105-D1 (see press release dated February 4, 2025 and March 12, 2025 respectively). The hole cut continuous high-grade gold mineralization (see Table 2) with assays results as follows:

• • 50.50 metres @ 5.66 g/t gold, 13 g/t silver from 526.10 metres downhole including:
    • 8.80 metres @ 10.56 g/t gold, 23 g/t silver from 528.20 metres downhole and
    • 17.95 metres @ 9.48 g/t gold, 18 g/t silver from 545.05 metres downhole

APC106-D2 was extended to the southwest using the new higher capacity drill rig from a previously failed directional hole from Pad 19. The hole intersected the Ramp Zone approximately 200 metres to the east and 50 metres vertically beyond all prior drilling with assays results as follows:

• • 70.00 metres @ 2.00 g/t gold, 5 g/t silver from 693.80 metres downhole including:
    • 8.00 metres @ 3.52 g/t gold, 8 g/t silver from 711.00 metres downhole and
    • 25.05 metres @ 3.44 g/t gold, 7 g/t silver from 738.75 metres downhole

APC106-D2 is the deepest intersection of mineralization at Apollo to date (The Ramp Zone is located at the bottom of Apollo) at approximately 1,300 metres below surface, where it remains open for further expansion. The aim of the current program at the Ramp Zone is to try and extend the system by an additional 200 metres or more both vertically and laterally.

The Ramp Zone, which begins at approximately 1,000 metres below surface and now extends to 1,300 metres below surface is a reduced intrusion related gold system and has many similarities to the Marmato Deeps deposit located a mere 1.75 kilometres to the southeast. The gold bearing, sulphide mineral assemblages are very similar to those seen in Aris Mining's Marmato Deeps deposit which starts, coincidentally, at the same elevation as the Ramp Zone. An underground mine designed to produce gold from the Marmato Deeps deposit is currently under construction. Aris Mining's Marmato Deeps deposit hosts an NI43-101 compliant resource estimate of 3.76 million ounces of gold in the measured plus indicated category at 2.54 g/t gold (hosted within 46 million tonnes) and 2.54 million ounces of inferred gold at 2.39 g/t gold (hosted within 33.1 million tonnes). The dimensions of the Marmato Deeps deposit measure up to 950 metres of strike x 300 metres width x 750 metres vertical and remains open. Similar to Marmato Deeps, gold and silver mineralization in the Ramp Zone is associated with sulphides containing minor amounts of bismuth, tellurium and in some places arsenopyrite in association with pyrite and pyrrhotite in veins, veinlets and vein stockwork. One key difference between early assay results for drill holes from the Ramp Zone compared to the Marmato Deeps deposit is that the gold grades from early drilling at the Ramp Zone thus far are significantly higher. The Company believes there are two primary reasons leading to the higher gold grades at the Ramp Zone which are as follows:

• Mineralization is hosted within a breccia, which has more porosity for metal bearing fluids to be deposited than the pre-cursor porphyry host rock at Marmato Deeps;
  
  
• The Ramp Zone mineralization continues to be overprinted in places by the same late-stage high-grade porphyry veins ("CBM veins") that overprint the balance of the Apollo system drilled to date from surface.
