Pampa Metals report that drilling to test for lateral and depth extensions below previous high grade porphyry copper-gold intersections at the Piuquenes Cu-Au porphyry project has successfully intersected wide intervals of both secondary and primary mineralization. Excellent progress is being made and drilling is continuing.
Diamond drillhole PIU-01 (refer figure 1), designed to extend Cu-Au mineralization to depth on the southwestern margin of the Piuquenes Central porphyry, intersected a 160m thick zone of supergene copper enrichment between 220m to 380m downhole, coincident and overlapping with primary mineralization from 350 meters. PIU-01 has been plotted to approximately 900 meters downhole depth, with primary mineralization continuing from 350m to the current hole depth of approximately 600m.
An initial batch of core samples have been prepared and dispatched to the ALS laboratory in Mendoza, with first assay results expected shortly.
“We are very pleased to have intersected a thick copper supergene enrichment blanket on the first hole of a multi-campaign exploration program testing the Piuquenes Project’s exceptional potential. We now eagerly await our first assay results and look forward to driving shareholder value over the short, medium, and long-term as we continue to test the depth and lateral extensions of the previously reported high-grade copper-gold intervals at Piuquenes Central, and thereafter drill testing Piuquenes East and other nearby targets on the property.”

Geology and Mineralization – Diamond Drillhole PIU-01
Weak-moderate porphyry A-type quartz stockworks are present from approximately 150 m downhole, increasing in intensity from 220m depth. Supergene copper enrichment is evident from 220m to 380m depth, partially coincident (from 288 m depth) with increasing intensity of porphyry A-type quartz vein stockworks and evidence of intermineral potassic alteration. A narrow zone of copper oxides is observed from 220 – 229 meters downhole.
Dense porphyry A-type quartz vein stockworks with chalcopyrite and traces of disseminated bornite mineralization hosted in potassic altered diorite porphyry were intersected from 350m to the current downhole depth of approximately 600 m. Drilling is continuing in strong mineralization.

* %CuEq values are calculated based on copper and gold metal prices: Cu = US$3.20/lb, Au = US$1,700/oz and Ag = US$ 20/oz. The formula utilized to calculate %CuEq is: Cu Eq Grade (%) = Cu Head Grade (%) + [(Au Head Grade (g/t) / 31.104) * (Au Price (US$/oz) / Cu Price (US$/lb) / 22.04) + [(Ag Head Grade (g/t) / 31.104) * (Ag Price (US$/oz) / Cu Price (US$/lb) / 22.0.
