Drill Holes Confirm New Porphyry Cu-Au Discovery

VANCOUVER - Pampa Metals Corp. reported that drill hole PIU-06 2025DDH (PIU-06) has confirmed a new porphyry copper-gold discovery, located immediately to the north of emerging Altar North system, within the broader Piuquenes-Altar cluster. PIU-06 was the first drill hole designed to test the Piuquenes East porphyry vein and breccia system mapped at surface and is collared approximately 800 m east of the Company’s Piuquenes Central deposit. PIU-06 intersected porphyry A and B-type quartz stockwork veining and reported a significant mineralized interval as follows: 208m @ 0.31% Cu, 0.13 g/t Au, 1.24 g/t Ag (from 292m), including 98m @ 0.49 % Cu, 0.16 g/t Au, 1.26 g/t Ag (from 292m)

The discovery of an entirely new porphyry breccia system at Piuquenes East, well removed from the Piuquenes Central system, is considered extremely encouraging. Piuquenes East is a multi-phase porphyry breccia system at the very earliest stages of exploration, entirely open to the north, west and east with no drilling testing any of these potential extension areas.  

Joseph van den Elsen,President and CEO, said, “To have returned such significant results from the first hole into the Piuquenes East discovery is an important milestone for Pampa Metals and validates the Piuquenes project as host to multiple porphyry systems and a company making asset. Importantly, we have now confirmed Piuquenes East as a zoned-multi-phase porphyry-breccia system which is entirely open in all directions, and where we believe the core of the system is yet to be tested. We are excited to continue our systematic exploration of the full 2,500-hectare tenure package through further geological mapping, geophysics and drilling. a zoned porphyry-breccia Concurrently, we continue to move towards completion of the acquisition of Rugby Resources and its Cobrasco and Mantau projects, and the resulting creation of a leading, multi-asset South American porphyry copper explorer, and look forward to recommencing drilling at Cobrasco in 2H 2025.”
