Andina Copper Strikes High-Grade Gold-Copper at Piuquenes North

Andina Copper Corporation (TSX-V: ANDC | FSE: FIR | OTCQB: PMMCF) has announced a significant new copper-gold porphyry discovery at its Piuquenes North target in San Juan, Argentina. Drillhole PIU13 returned 468 meters grading 0.50% copper, 0.30 g/t gold, and 3.04 g/t silver from 700 meters depth, including a high-grade interval of 164 meters at 0.70% copper, 0.44 g/t gold, and 4.19 g/t silver. The mineralization is hosted within a multiphase porphyry system with intense quartz vein stockworks and potassic alteration, featuring chalcopyrite and bornite. This discovery confirms the presence of a new porphyry center adjacent to the Altar copper-gold project (Aldebaran Resources Inc.) and alongside the previously identified Piuquenes Central and East systems. The MT geophysical anomaly at Piuquenes North, measuring approximately 800 by 700 meters, remains largely untested, with only two holes drilled to date. President and CEO Joseph van den Elsen expressed enthusiasm, noting that the results validate the potential of the San Juan Miocene belt, which hosts other major deposits like El Pachon (Glencore), Los Pelambres (Antofagasta), and Los Azules (McEwen Copper). The company plans further drilling to expand the discovery.

Andina Copper’s exploration success underscores the strategic value of its Piuquenes project, located in a prolific mining region. The company, listed on multiple exchanges, holds significant discoveries along the Andean porphyry belt in Colombia, Argentina, and Chile. The integration of geophysics, geology, and drilling has rapidly advanced the project since January 2025. The company’s Andina Copper Corporate Presentation provides further details on its portfolio and strategy. With the Piuquenes North discovery, Andina Copper has demonstrated its ability to generate new exploration targets and deliver high-grade intercepts, positioning itself as a key player in the copper-gold exploration space.

The company’s technical team, led by Qualified Person Gustavo Zulliger, has implemented rigorous QAQC protocols, including certified reference materials and blanks. Drillhole PIU13 intersected mineralization from 664 to 1,168 meters downhole, with the highest grades associated with early mineral porphyry phases. In contrast, PIU12, located 600 meters away, returned lower-grade intercepts, indicating the periphery of the system. The company is now designing a follow-up drill program targeting the north-northeast continuation and depth extensions of the MT anomaly. This news release, originally distributed via NEWMEDIAWIRE, highlights Andina Copper’s commitment to advancing its projects and creating shareholder value through systematic exploration.
