TORONTO, Ontario — February 24, 2026 — Leads & Copy —
Collective Mining Ltd. (NYSE: CNL) (TSX: CNL) has announced assay results for a portion of a directional diamond drill hole at the Apollo system’s Ramp Zone, designed to evaluate and expand the high-grade area along strike and at depth.
The Ramp Zone, located at the base of Apollo, starts approximately 1,000 meters above sea level (MASL), positioning it at the same elevation as a potential future underground access tunnel. Drilling has outlined continuous mineralization from the surface to more than 1,450 vertical meters.
Ari Sussman, Executive Chairman, noted the promising initial results from Ramp Zone hole APC150-D1, which intersected broad, continuous high-grade mineralization. He expressed anticipation for assays from the remaining 370 meters of core, which contains visible gold. Sussman also noted the visual confirmation of Ramp-style mineralization in hole APC140-D5, drilled on the western breccia margin, potentially confirming the hypothesis that high-grade gold could encircle the outer margins of the entire breccia body.
Hole APC150-D1 intersected 54.55 meters @ 7.04 g/t gold and 16 g/t silver from 378.65 meters down deflection (1,255 meters down hole from mother hole collar) including 17.85 meters @ 11.37 g/t gold and 22 g/t silver and bottoming in high-grade with the final assay result received thus far from the lab averaging 1 metre @ 26.70 g/t gold and 67 g/t silver.
Multiple instances of visible gold have been logged in select locations across the remaining 370.25 meters of core and await assay results, including near the bottom of the hole. If mineralized, this would position APC150-D1 as the deepest and northeasternmost intercept ever recorded at Ramp.
Visual logging of hole APC140-D5, the first hole ever drilled at depth on the western margin of the breccia body, has intersected at least 20 meters of Ramp Zone style of mineralization. If assay results confirm the presence of gold in this core section (expected in late March), it would validate the hypothesis that Ramp Zone mineralization has the potential to extend beyond the southeast breccia margin and could encircle the breccia’s entire circumference. To date, the Company has confirmed that high-grade gold in the Ramp Zone covers 315 meters of the outer, southeast breccia margin with an additional 1,200 meters of outer breccia margin still to be drill tested.
Three deep-capacity diamond rigs are currently operating at the Ramp Zone, with two additional rigs expected to arrive next month. Collective has completed 168,000 meters of diamond drilling across the Guayabales and San Antonio projects, including 110,500 meters at the Apollo system.
The company, with US$135 million in cash as of December 1, 2025, is fully funded for its 2026 program, which includes up to 100,000 meters of additional drilling. Up to fourteen rigs are anticipated to be operating across both projects before the end of Q1, 2026, with numerous high-priority holes pending assay results.
Hole APC150-D1 was drilled in a northernly direction as a wedge directional hole from mother hole APC-150D (Pad 34) and potentially extended the Ramp Zone along strike and depth. Assays results received to date, covering only the top portion of the hole, are as follows: 11.30 metres @ 3.04 g/t gold and 9 g/t silver from 333.45 metres down deflection and; 54.55 metres @ 7.04 g/t gold and 16 g/t silver from 378.65 metres down deflection including 17.85 metres @ 11.37 g/t gold and 22 g/t silver. Assay results for the outstanding 370.25 metres of drill core are expected before the end of March.
Hole APC140-D5, drilled to the southwest as a directional hole from mother hole APC-140D (Pad 29), was designed to test the western margin of the breccia body for Ramp Zone style mineralization at elevations between 800-900 MASL. Drill core logging indicates that more than 20 metres of potential Ramp Zone style mineralization has been intersected, with assay results anticipated in late March.
The Ramp Zone, commencing at approximately 1,000 MASL, is classified as a reduced intrusion-related gold system, sharing mineralogical similarities with the nearby Marmato Deeps deposit owned by Aris Mining. The company cautions that information regarding the Marmato Lower Mine is not necessarily indicative of mineralization in the Ramp Zone. At Ramp Zone, mineralization occurs with pyrite and pyrrhotite, accompanied by minor bismuth, tellurium, and locally arsenopyrite bearing sulphides, hosted in veinlet stockworks, cracks and miarolitic cavities of the breccia body. Alteration is dominated by muscovite, albite, and sericite.
A key distinguishing feature at Ramp is the significantly higher gold grades encountered to date compared to Marmato Deeps. The Company attributes this superior grade profile primarily to the host rock: mineralization at the Ramp Zone is emplaced within a porous crackle breccia matrix, which provides greater permeability for metal-bearing fluids than the porphyry host rock at Marmato Deeps.

Founded by the team that developed and sold Continental Gold Inc. to Zijin Mining for approximately $2 billion in enterprise value, Collective is a gold, silver, copper and tungsten exploration company with projects in Caldas, Colombia. The Company’s two projects are located directly within an established mining camp with ten fully permitted and operating mines.
The Company’s flagship project, Guayabales, is anchored by the Apollo system, which hosts the large-scale, bulk-tonnage and high-grade gold-silver-copper-tungsten Apollo system. The Company’s objectives at the Guayabales Project are to expand the newly discovered high-grade Ramp Zone along strike and to depth, drill test the new Hanging Wall Vein Zone and drill a series of greenfield generated targets on the property.
Additionally, the Company is drilling its optioned San Antonio Project (can earn up to 100% interest) as it hunts for new discoveries and looks to aggressively extend to the south the recently discovered high-grade silver system made at the Pound target. The San Antonio Project is located between two to five kilometers east-northeast of the Guayabales Project and could potentially share infrastructure given their proximity to each other.
Management, insiders, a strategic investor and close family and friends own 45.3% of the outstanding shares of the Company and as a result, are fully aligned with shareholders. The Company is listed on both the NYSE American and TSX under the trading symbol “CNL”.
