Marimaca Copper (TSX: MARI) announced Monday the discovery of the northern extension of the Pampa Medina deposit, located approximately 26km from its Marimaca Oxide Deposit (MOD).  

The company is aiming to advance a definitive feasibility study (DFS) for its flagship project — the namesake Marimaca copper asset in Chile’s Antofagasta region.

Marimaca also reported results from the maiden scout drilling program at the Pias target, located northwest of Pampa Medina within the broader Sierra de Medina property block. 

Hole SMR-01 was drilled 400m north of the known northern extent of the Pampa Medina deposit, intersecting significant oxide copper and chalcocite mineralization from 272m-462m, transitioning to dominantly chalcopyrite-bornite mineralization from 462-650m, the company said.  

Highlights from SMR-01 are 400m at 0.49% CuT from 250m including: 216m at 0.70% CuT from 250m (dominantly oxides), including 102m at 1.20% CuT from 250m, including 76m at 1.57% CuT from 276m, including 18m at 5.11% CuT from 320m, 100m at 0.36% CuT from 550m (dominantly sulphides), including 32m at 0.62% CuT from 618m, including 2m at 3.43% CuT from 648m.  

Three additional drill holes remain pending at Pampa Medina, targeting both west and north step-outs, the company said, adding that it is currently considering an expanded discovery exploration program at Pampa Medina Norte in 2025.
