Pampa Metals Corp. (CSE:PM)(FSE:FIRA)(OTCQX:PMMCF) is pleased to advise that diamond drill testing of the Buenavista target commenced on March 31, 2023. As previously advised, a ~2,100m diamond drill program of 3 deep holes designed to test coincident geological, geochemical, and geophysical anomalies at the Buenavista target and the Block 4 project more broadly is expected to be completed within 2 months, with assay results available during June.

The first drill hole is centred on the dacite porphyry and phreatomagmatic breccia complex with quartz-veinlet stockworking at Buenavista, and is initially targeted to a depth of about 750m. The drill hole diameter will be HQ, with the option of reducing to NQ at depth, depending on drilling conditions.

Block 4 Project & Buenavista Target - Summary Description of the New Porphyry Cu-Mo-Au Target

• Block 4 is the Company's priority project, with the Buenavista Target displaying characteristics indicative of a large, fertile, Tertiary aged, porphyry copper-molybdenum-gold system, located along the world's preeminent porphyry copper belt in northern Chile;
• Intense, sub-cropping, quartz-veinlet stockwork occurs at Buenavista within a dacite porphyry and phreatomagmatic breccia complex, flanked by a quartz-sulfide breccia to the west and skarn-type mineralization to the east, and is coincident with key geochemical and geophysical anomalies;
• Anomalous soil and trench geochemical values of copper, molybdenum, and gold (and other pathfinders), in a heavily supergene leached desert environment, coincide with mapped geology, hydrothermal alteration, magnetic and induced polarisation (IP) geophysical anomalies, and other complementary data including 3D modeling and age dating;
• The Buenavista Target footprint comprising geological, geochemical, and geophysical anomalies is approximately 1.5 km E-W by 1 km N-S along a significant geological structure;
• The presence of several other 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.
