Andina Copper Corporation (TSX-V: ANDC) announced assay results from drillhole PIU13 confirming a new porphyry copper-gold discovery at Piuquenes North, with 468m grading 0.50% Cu and 0.30 g/t Au, highlighting significant upside potential as only a small portion of the large geophysical anomaly has been tested.

Andina Copper Corporation (TSX-V: ANDC | FSE: FIR | OTCQB: PMMCF) reported diamond drill assay results from drillholes PIU12 and PIU13 at the newly generated Piuquenes North target in San Juan, Argentina. The drilling, which targeted a large discrete magneto-telluric (MT) geophysical anomaly, has confirmed a new porphyry copper-gold system.
Assay results for 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 higher-grade interval of 164 meters at 0.70% copper, 0.44 g/t gold, and 4.19 g/t silver from 924 meters. Mineralization is hosted within a multiphase porphyry system intersected between 664 and 1,168 meters downhole, characterized by intense quartz vein stockwork and potassic alteration with chalcopyrite and bornite, consistent with a high-temperature porphyry core.
Drillhole PIU12, collared approximately 600 meters east-northeast of PIU13, intersected shorter intervals of mineralization within a pre-mineral porphyry, interpreted as the periphery of the system. The two holes have only tested a small part of the MT anomaly, which measures approximately 800 by 700 meters and trends north-northeast, remaining open in all directions.
The Piuquenes district now hosts multiple porphyry centers, including the newly discovered Piuquenes North, and the previously reported Piuquenes Central and Piuquenes East systems, all immediately adjacent to Aldebaran Resources Inc.'s Altar copper-gold porphyry project. The region, part of the San Juan Miocene porphyry belt, also includes major projects such as El Pachon (Glencore), Los Pelambres (Antofagasta plc), and Los Azules (McEwen Copper).
Andina Copper’s President and CEO Joseph van den Elsen commented, "We are extremely pleased with the results from our first drillholes at Piuquenes North. High-grade Cu-Au values from PIU13 confirm a new discovery, proximate to the high-grade near-surface mineralization at Piuquenes Central. Only a fraction of the large geophysical anomaly has been tested, and we are now designing the next phase of drilling to expand on this potentially significant new porphyry discovery."
The company plans to integrate final assay results with geological logging to refine a three-dimensional model and design a follow-up drill program targeting down-dip and along-strike extensions.
