Pampa Medina drilling hit 6m at 12.0% copper within 26m at 4.1% (SMRD-13) and 40m at 2.1% (SMD-02), building on the earlier SMD-01 and SMR-01 results. A second rig and 14 holes are planned; the Pampa Medina PEA is paused. The main-deposit feasibility study is said to be near-complete.

Hole SMD-01 at Pampa Medina Norte hit 68m at 1.20% copper and 40m at 1.07%, confirming the oxide discovery hole SMR-01 (Dec 2024) and finding new sulphide mineralisation at depth. Assays from 600-950m and two more deep holes are pending.

Re-interpretation of 77,000m+ of historical drilling and five new holes indicate a linked oxide copper 'manto' system across about 5km by 4km at Pampa Medina, 25km from the main deposit. Best new hole SMR-05 hit 32m at 0.81% copper. Expanded 2025 drilling is being considered.
