Pampa Metals Corp. advised 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. Historically, Inmet Mining Corporation (IMC, subsequently acquired by First Quantum in 2013) intersected significant copper and gold mineralization at Piuquenes 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).
