Collective Mining (CNL) completes road to 2026 Guayabales adit
Rhea-AI Filing Summary
Collective Mining Ltd. is advancing early works for an exploration adit at its Guayabales Project in Caldas, Colombia. A 1.8-kilometer access road from the Pan American Highway to the planned portal has been completed, allowing immediate start of portal platform and box-cut construction. The company targets commencement of adit construction in Q4-2026, followed by underground exploration drilling at the Trap East target in Q1-2027, with Trap Main drilling expected in H2-2027 and Ramp Zone and Plutus in 2028. Historical drilling at the Trap system shows long mineralized intercepts and localized high-grade veins, and the adit is planned to intersect the southeastern end of the Trap mineralized corridor while also supporting future exploration and potential project infrastructure.

Collective Mining Advances Guayabales Exploration Adit Toward Q4-2026 Construction; Underground Drilling at Trap to Commence in Q1-2027
- A 1.8-kilometer switch-back access road connecting the Pan American Highway to the proposed exploration adit portal has been completed; portal platform and box-cut activities are set to begin immediately
- With all required permits in hand, construction of the exploration adit remains on track to commence in Q4-2026
- Underground exploration drilling is expected to begin in Q1-2027 at the newly identified Trap East greenfield target, marking the start of an underground exploration program designed to systematically test Trap, Apollo's Ramp Zone and Plutus
MIAMI, Aug. 18, 2026 /CNW/ -- Collective Mining Ltd. (NASDAQ: CNL) (TSX: CNL) ("Collective" or the "Company") is pleased to report that considerable progress has been made across the engineering, site preparation, and operational readiness workstreams required to support the development of the exploration adit at the Company's Guayabales Project in Caldas, Colombia. With the 1.8-kilometer access road now complete, the Company is advancing immediately into portal platform and box-cut activities. The exploration adit is on schedule for commencement of construction in Q4-2026 and underground exploration drilling at Trap beginning in Q1-2027.
An accompanying video featuring recent footage of the early construction activities underway is available here: https://youtu.be/WHDISklkvfo
Ari Sussman, Executive Chairman, stated: "We are excited to begin drilling the Trap System from underground, as we will be able to rapidly test the system from suitable drilling angles while testing for extensions to the mineralization. Following a recent detailed review with our geological team, I am confident that Trap has all the potential to develop into a second large-scale precious-metal system at Guayabales. A key advantage to the Trap System is its proximity to both the exploration adit portal and the proposed future mining infrastructure. Should our underground drilling confirm the system as we expect, Trap would provide a second independent working front alongside Apollo, enhancing mill feed flexibility in a future mining scenario. On a final note, given the amount of mineralization we have found across the Guayabales Project through limited surface drilling to date, I am not discounting the possibility that we end up discovering yet another mineralized system as the exploration adit advances to its final destination at the Apollo System."
Ned Jalil, Chief Executive Officer, commented: "We are pleased with the rapid progress being achieved on site as we advance toward breaking ground on the exploration adit in Q4-2026. Once established, the adit will fundamentally expand the way we can explore Guayabales. Underground access will enable us to drill-test Apollo's Ramp Zone, the Trap System and the Plutus Target over more than a vertical kilometer from optimal orientations that are not available from surface. We remain firmly on track to meet our planned milestones and look forward to providing further updates as work progresses."
Details (See Figures 1-3)
A 1.8-kilometer access road to the portal location has been completed by upgrading an existing path from the Pan American Highway. The road now reaches the planned portal area, enabling immediate commencement of a box-cut and portal platform construction.
Early works remain aligned with the Company's execution schedule, which targets the start of adit construction in Q4-2026. Under the current timeline, initial underground drilling of the newly generated greenfield target Trap East is scheduled for Q1-2027. Drilling of the Trap Main System is expected to begin in H2-2027 once the adit has advanced sufficiently to allow construction of a cross-cut, followed by drilling of both the Plutus Target and the Ramp Zone in 2028.
The selected portal location and access-road alignment lie within the area anticipated for future project infrastructure. Proximity to the Pan American Highway and existing power infrastructure will support efficient execution of the current exploration program and longer-term project planning.
Consistent with the Collective Way, the Company is prioritizing local employment and procurement opportunities. Much of the current early works program workforce has been sourced from communities within the Department of Caldas.
All activities are being completed in accordance with the Company's health and safety standards. Safety measures have been embedded into the engineering designs, contractor management and execution plans. The Company continues to advance according to all applicable regulations required by regional authorities to support current and future phases of the project.
Trap System – Historical Drill Highlights*
Mineralization at the Trap system outcrops at surface and has been sparsely drill tested along a 1.4-kilometer-long northwest-southeast directed corridor. The system extends up to 900 meters vertically below surface, and remains open along strike and at depth. Notably, the planned exploration adit is positioned to intersect the currently known southeastern end of the Trap mineralized corridor.
The Company currently has one rig testing for mineralization extending up to 200 meters further northwest than all prior drilling, with initial results expected in late September. Previously announced drilling highlights demonstrated both broad zones of continuous mineralization and discrete high-grade vein zones, including:
- 632.25 meters @ 1.10 g/t AuEq from 172.65 meters, including 51.50 meters @ 2.73 g/t AuEq and 46.35 meters @ 2.41 g/t AuEq (TRC-7A)
- 646.00 meters @ 0.81 g/t AuEq from 19.50 meters, including 301.50 meters @ 1.01 g/t AuEq (TRC-2)
- 174.45 meters @ 1.19 g/t AuEq from 485.15 meters, including 40.85 meters @ 3.76 g/t AuEq (TRC-11)
- 30.00 meters @ 4.96 g/t AuEq from 11.85 meters (TRC-14)
- 200.85 meters @ 1.06 g/t AuEq from 4.55 meters, including 40.50 meters @ 4.01 g/t AuEq (TRC-30)
- 2.80 meters @ 234.15 g/t gold from 122.00 meters, including 0.80 meters @ 816 g/t gold (TRC-26)
- 1.30 meters @ 49.30 g/t gold from 18.15 meters (TRC-25)
