Pampa Metals Corp. provided a summary of its highly successful maiden drill program at the Piuquenes porphyry project, San Juan province. The Piuquenes project was optioned on 30 November 2023 and the Company mobilized a 3 diamond drillhole program for 2,592m on 7 December 2023.

As reported on 18 March 2024, 6 May 2024 and 23 May 2024, each of the three drillholes intersected significant intervals of copper, gold and silver mineralization as follows:
Hole PIU01-2024DDH
• 422 m @ 0.48% Cu, 0.61 g/t Au, 2.9 g/t Ag (198-620m);
• including 132 m @ 0.71% Cu, 0.85 g/t Au, 4.3 g/t Ag (220-352m)
• Including 80 m @ 0.6% Cu, 0.77 g/t Au, 3.2 g/t Ag (468-548m)
Hole PIU02-2024DDH
• 448 m @ 0.42% Cu, 0.46 g/t Au, 2.44 g/t Ag (214-662m)
• including 188m @ 0.59% Cu, 0.63 g/t Au, 3.49 g/t Ag (450-638m)
• including 126 m @ 0.66% Cu, 0.74 g/t Au, 3.94 g/t Ag (450-576 m)
Hole PIU03-2024DDH
• 801 m @ 0.40% Cu, 0.51 g/t Au, 2.87 g/t Ag (54 - 855m (EOH))
• including 518 m @ 0.53% Cu, 0.73 g/t Au, 3.45 g/t Ag (192 - 710)
• including 176 m @ 0.71% Cu, 0.74 g/t Au, 4.86 g/t Ag (192 - 368)
• including 64 m @ 0.75%, 1.2 g/t Au, 4.60 g/t Ag (554 - 618m)
• including 32m @ 0.64% Cu, 0.71 g/t Au, 4.54 g/t Ag (642 - 674m)
Key Technical Findings
• Delineation of a continuous body of high-grade porphyry Cu-Au mineralization from surface to depths of greater than 800m at Piuquenes Central.
• High grade Cu-Au mineralization remains open to depth and to the north-east.
• Confirmation of a multi-phase porphyry system, with strongly developed A type quartz stockwork veining hosting extensive chalcopyrite and bornite mineralization carrying significant copper and gold grades.
• Abundant bornite mineralization encountered both centrally and within the outer margins of the porphyry system, highlighting significant potential for an underlying bornite rich core to the deposit.
• Low average arsenic content reported in assays.
Current Activities
Following completion of its maiden drill program at Piuquenes, the Company is now focused on the integration of recent drilling data with historical information. Concurrent work programs include geological modelling, grade and lithology interpretation aided by multi-element geochemical data, and reprocessing and interpretation of historical geophysical data.
Metallurgical testing and mining concept studies for Piuquenes Central are also being considered.
Preparations are underway for the next field season, which will include further drill evaluation of the Piuquenes Central deposit, the initial drill testing of Piuquenes East, field mapping and further geophysics if required.
