COLLECTIVE MINING REPORTS A NEW PRECIOUS METAL DISCOVERY AT ITS GUAYABALES PROJECT BY DRILLING 136.45 METRES AT 1.31 G/T GOLD EQUIVALENT AT THE PLUTUS TARGET

Collective Mining Ltd. has released assay results for two diamond holes drilled into the Plutus Northern corridor, which is one of a series of targets at the Guayabales project located in Caldas, Colombia. The Plutus Northern corridor forms part of the larger Plutus porphyry centre and is located approximately 1,000 metres east of the Apollo porphyry system.

Ari Sussman, executive chairman, commented: "Making a new discovery in only the second hole drilled in the Plutus Northern corridor as part of the 2023 exploration program is a testament to both the tenacity of our operating team on the ground and the robust geology of the intrusion complex at the Guayabales project. We remain steadfast in our goal of being aggressive with drilling to unlock as much value as we can in what we firmly believe is an emerging mining district. The area in which we operate has all the earmarks of evolving into a series of important and strategic deposits for Colombia and we are honoured to help push this initiative forward for our stakeholders and shareholders."

Plutus measures approximately 1,000 metres by 720 metres as outlined by a magnetic high which is coincident with copper and molybdenum soil anomalies measuring greater than 300 ppm (parts per million) and 20 ppm, respectively. The Plutus Northern corridor, situated within the northern portion of Plutus, hosts brecciated porphyry and overprinting CBM (carbonate base metal) vein mineralization within a northeast-southwest-trending corridor. The Plutus Northern corridor target zone is coincident with the transitional area between a magnetic high and a magnetic low as seen in magnetic susceptibility sections. It is worth noting that the Apollo porphyry system, as well as the area currently being drilled for the first time by the company at the Marmato Extension (ME) target, are also located in the same magnetic transition zone.

Details

This press release outlines results from two holes designed to test below new recently defined outcropping targets within the Plutus Northern corridor.

PNC-2 was drilled southwest from a new pad, PPad 1, to a maximum downhole depth of 579.40 metres (450 metres vertical due to topography). The hole entered a 35.10-metre mineralized zone at 65.30 metres down hole and is hosted in diorite and quartz diorite porphyry rocks with multiple quartz, magnetite, chalcopyrite and molybdenum veinlets (up to 2 per cent veinlet density) being observed. At a downhole depth of 143.20 metres, the hole intercepted a continuous zone of hydrothermal breccia for 185.80 metres with the cement matrix hosting 0.1 per cent chalcopyrite, 1 per cent pyrite, 0.2 per cent sphalerite and 0.1 per cent pyrrhotite. At 369.35 metres down hole, the hole entered a new zone of mineralization located below a recently identified outcrop and cut 136.45 metres of continuous hydrothermal breccia with overprinting CBM veinlets. This new mineralized zone hosts a sulphide cement matrix of chalcopyrite (up to 0.3 per cent), pyrite (up to 1.5 per cent), sphalerite (up to 0.6 per cent), galena (up to 0.5 per cent) and pyrrhotite (up to 0.7 per cent) with assay results as follows:

• 35.10 metres at 0.41 gram per tonne gold equivalent from 65.30 metres down hole (consisting of 0.20 g/t gold, two g/t silver and 0.10 per cent copper) in mineralized porphyry;
• 185.80 metres at 0.81 g/t gold equivalent from 143.20 metres down hole (consisting of 0.59 g/t gold, 13 g/t silver and 0.02 per cent copper) in hydrothermal breccia;
• 136.45 metres at 1.31 g/t gold equivalent from 369.35 metres down hole (consisting of 0.97 g/t gold, 20 g/t silver and 0.04 per cent copper) in hydrothermal breccia including:
  • 42.95 metres at 2.39 g/t gold equivalent from 462.35 metres down hole in breccia with overprinting sheeted CBM veinlets.

PNC-1 was drilled south-southwest from PPad 1 to a maximum downhole depth of 594.95 metres (490 metres vertical due to topography) and encountered diorites and quartz diorite porphyry rocks with secondary biotite alteration and veinlets of quartz, magnetite, chalcopyrite and molybdenum with assay results as follows:

• 22.45 metres at 0.32 g/t gold equivalent from surface (consisting of 0.19 g/t gold, one g/t silver and 0.04 per cent copper);
• 85.05 metres at 0.31 g/t gold equivalent from 53 metres down hole (consisting of 0.18 g/t gold, one g/t silver and 0.06 per cent copper);
• 39.35 metres at 0.35 g/t gold equivalent from 169.75 metres down hole (consisting of 0.11 g/t gold, four g/t silver and 0.09 per cent copper);
• 24.40 metres at 0.35 g/t gold equivalent from 254.90 metres down hole (consisting of 0.11 g/t gold, five g/t silver and 0.07 per cent copper);
• 31.35 metres at 0.53 g/t gold equivalent from 312.10 metres down hole (consisting of 0.25 g/t gold, six g/t silver and 0.09 per cent copper).

Based on drilling, the known mineralized dimensions of the Plutus Northern corridor measures 285 metres in strike by 250 metres width by 375 metres vertical and remains open in most directions for expansion.

Exploration drill program and assay update

The 2023 phase II drilling program is advancing on schedule with assay results reported for 41 holes and an additional 14 holes awaiting assay results from the lab.

With five diamond drill rigs now operating at site, the company is advancing with the following objectives:

1. Expanding the Apollo porphyry system both laterally and vertically. The company is currently advancing with directional drilling for the first time with the initial fan of four holes now complete. Additionally, the company is drilling a series of short holes from surface targeting extensions to the sheeted CBM vein systems located above and peripheral to the Apollo brecciated porphyry. Three drill rigs are actively drilling at Apollo.
2. Drill test the Marmato Extension (ME) porphyry centre for the first time in search of both a high-grade sheeted CBM vein system at shallow elevations and a potential buried porphyry system at depth. One drill rig is currently active at ME.
3. Drill test the Trap target in the northern portion on the Guayabales project. Three widely spaced reconnaissance holes were completed at Trap in 2022 with the discovery hole, TRC-1, assaying 102.2 metres at 1.53 g/t gold equivalent and containing similar mineralization to the Apollo porphyry system.
4. Fly airborne geophysics on the Plutus target ahead of first phase drilling of the large and untested coincidental copper- and molybdenum-in-soil anomaly covering the central and southern portion of the target area.
