Pampa Metals Mobilizes Follow-Up Diamond Drill Testing of the Piuquenes Porphyry Copper-Gold Project

Pampa Metals Corp. ("Pampa Metals" or the "Company") (CSE:PM)(FSE:FIR)(OTCQB:PMMCF) is pleased to advise that it has formally contracted Eco Minera S.A, an Argentinean drilling company with over 20 years' experience operating in the San Juan province, to complete a ~2,500m diamond drill program designed to test the depth and lateral extension of known mineralization at Piuquenes

Drilling is scheduled to commence in January 2024, with preparatory works already underway, and to be completed in 3 months. Assay results are expected progressively from March.

Piuquenes Porphyry Copper-Gold Project

Historically, Inmet Mining Corporation (IMC, subsequently acquired by First Quantum in 2013) intersected significant copper and gold mineralization at Piuquenes (refer 30 November 2023 News Release) including:

• 413.5 m (167-580.5 m) @ 0.47% Cu and 0.52 g/t Au (0.87% CuEq)*;
• 67.5 m (207-274.5 m) @ 0.63% Cu and 0.51 g/t Au (1.02% CuEq)*; and
• 158 m (3-161 m) @ 0.32% Cu and 0.6 g/t Au (0.78% CuEq)*.

In November 2023, Pampa Metals assayed and re-logged Anglo-American's 2016 diamond borehole of 920.2 m length which had crossed the mineral zones drilled by IMC. These results were reported in a 5 December 2023 News Release and included:

- 558.2 m (362-920.2 m EOH) @ 0.38% Cu & 0.42 g/ Au & 2.4 g/t Ag (0.73% CuEq)*
Including:
- 296 m (362-658 m) @ 0.5 % Cu & 0.5 g/t Au & 2.7 g/t Ag (0.91% CuEq)*,
- 180 m (362-542 m) @ 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)*

Joseph van den Elsen, the Company's President and CEO, stated: "We are delighted to have not only secured the Piuquenes Project but to have been able to swiftly mobilize follow-up testing of the depth and lateral extension of the relatively shallow and significant, high-grade intervals of mineralization. We now look forward to updating our shareholders and the market on the results and the development of an aggressive, multi-campaign exploration program."
