Pampa Metals Advances Buenavista Porphyry Copper Target Drill Testing

VANCOUVER, April 19, 2023 - Pampa Metals Corp. ("Pampa Metals" or the "Company") (CSE:PM)(FSE:FIRA)(OTCQX®:PMMCF) is pleased to advise that it has completed ~550m of the planned ~2,100m diamond drill program designed to test coincident geological, geochemical, and geophysical anomalies at its Buenavista target, and its Block 4 project more broadly. The presence of several geophysical anomalies under post-mineral covered portions of the Block 4 property is suggestive of a potential "cluster" of porphyry copper-molybdenum-gold systems, a characteristic typical of some major porphyry copper districts in Chile and worldwide.

As previously advised, the program commenced on 31 March 2023 and completion by the end of May remains on schedule, with assay results expected in June.

The Company also continues to actively advance its broader portfolio of seven 100% owned projects, all located in Chile and prospective for porphyry copper systems, with a view to developing a pipeline of drill ready prospects. Concurrently, the Company continues due diligence on possible acquisitions of large porphyry copper-molybdenum targets capable of complementing its existing portfolio.
