Collective Mining Unveils Major Discovery at San Antonio Project with Copper-Gold Porphyry System

Major Gold-Copper Finding at San Antonio Project



On May 5, 2025, Collective Mining Ltd. announced an important milestone at their San Antonio Project, revealing the presence of a gold-copper porphyry system. Drill hole SAC-11, aimed at exploring the northern section of the Pound target, intersected 290.20 meters of mineralization averaging 0.84 grams per tonne (g/t) gold equivalent. This includes notable high-grade sections such as 40.90 meters at 1.44 g/t and 31.20 meters at 1.23 g/t gold equivalent.

The discovery represents not only a significant finding in terms of its dimensions but also highlights the potential richness of the mineralization, characterized by robust veins of quartz and chalcopyrite. Richard Tosdal, a renowned porphyry expert and Special Advisor to the Company, speculates that a larger mineralized copper-gold system could be located near the drill intercept, which has propelled the firm to ramp up their drilling operations.

Currently, two drill rigs are being mobilized to the Pound target to capitalize on this promising discovery. The San Antonio project itself spans a well-defined 2.5-kilometer mineralized corridor, which houses four additional drill-ready porphyry targets aside from Pound. Given the initial success at Pound, Collective Mining plans to aggressively continue drilling through the year, with the objective of examining all targets within the mineralized corridor.

Ari Sussman, Executive Chairman of Collective Mining, expressed enthusiasm about the project's potential. He noted that the high-density occurrence of stockwork veins in metagabbro country rocks adds a compelling layer of promise for the project, indicating that it may lead to a system with high-grade output. Sussman emphasized that drilling will intensify now, suggesting that the key to understanding the extent of the potential lies in rapidly increasing exploration efforts at the site.

The extensive drilling program anticipated for 2025 totals 70,000 meters, consisting of nine operating drill rigs. Of these, two are currently dedicated to the San Antonio Project while seven are deployed at the nearby Guayabales Project. Two additional high-capacity rigs have also been procured, slated to assist in deep exploration at the Ramp Zone of the Apollo system commencing in early Q3 2025.

Aside from the promising assays from SAC-11, there have been previous drillings at the Pound target dating back to 2021 that showcased gold-bearing breccia with mineralization continuing through the drill holes. The 2024 surface work at this site identified critical indications supporting the porphyry hypothesis, leading the company to elevate its drilling activities into the current year.

The Pound target is surrounded by surface anomalies of gold and copper, covering a substantial area of 650 by 550 meters, and remains open for further exploration. Additionally, next steps involve not just following up on the results at Pound, but also addressing other promising targets in the mineralized corridor, including the Real, COP, and Euro targets.

Excitement is building around the implications of this discovery, given that the San Antonio and Guayabales projects are in proximity to the famed Marmato Mine, known for its rich deposits. Industry experts believe that Collective Mining may be on the cusp of a significant breakthrough in their exploration efforts, reaffirming their commitment as they intensify their focus on the potential of the San Antonio Project.

With promising grades and a comprehensive drilling strategy, Collective Mining stands at the forefront of a promising exploration effort that could redefine their position within the mining sector, particularly in South America where gold and copper are increasingly sought after commodities. Stakeholders and investors will be watching closely as the drilling progresses and further assay results are generated to gauge the full potential of this discovery.
