Pampa Metals Corp. announced the assay results from the PIU16-DDH01 diamond drillhole (920.2 m) completed at the Piuquenes Project in the 2015-2016 season. Results include: 558.2 m (362-920.2 m EOH) 0.38% Cu & 0.42 g/t Au & 2.4 g/t Ag (0.73% CuEq); Including: 296 m (362-658 m) @ 0.5 % Cu & 0.5 g/t Au & 2".

A 558 m (362-542 m) section was sent to ALS Mendoza for Au fire 30 gram Au fire assay (Au-AA23) and ICP multi-element 4-acid digestion (ME-MS61) assays. Following review and interpretation of the assay results and a thorough Qa/Qc process, the Company reported a significant section of copper-gold-silver mineralization of: 558.2 m ("362-658 m") 0.5% Cu & 0.5 g-t Au & 2.7 g/t Ag (0.91% CuEq), 180 m (362-542m) 0.71% Cu & 0.61 g/t Au & 3.8 g/t Ag (1.22% CuEq); and 130 m (362-492 m) 0.81% Cu & 0.6 g/t Au & 4 g/t Ag (1".31% CuEq). The re-logging and interpretation of the assays indicates that primary mineralization is related to Cu-Au porphyry hosted quartz veins and remains open at depth.

The shallow overlay is associated with supergene enrichment, with some copper oxides observed at surface. Assay of the PIU16-DD H01 drillhole was based on samples of 2m intervals initially cut by Anglo-American Argentina at the drill platform using a hydraulic press. The first evidence of copper oxides at Piuquenes was reported in 1970 by MInera Aguilar, who subsequently completed the first exploration program between 1973-1975.

Between 1995 and 1997, Inmet Mining Corporation (IMC) completed a heli-magnetic/radiometric survey, surface geology, rock and soil geochemistry, ground magnetics, PD-IP and eight diamond drillholes for a total of 1,894.2m. Subsequently, in 2015-2016, Anglo American Argentina (AAA) completed detailed 1:2,500 geology and geochemistry, 17.8 km of gDAS24 deep 3D PD-IP/NSMT and a single 920.2 m diamond drill hole. Since its discovery, the Piuquenes Copper-Gold porphyry has until now remained privately held.
