Pampa Medina Norte Discovery Extended

VANCOUVER - Marimaca Copper Corp. reported on further drilling at Pampa Medina Norte, the recently discovered northern extension of the Pampa Medina Deposit. The latest result from hole SMD-01, follows discovery hole - SMR-01 which identified this northern extension of the Pampa Medina deposit, located approximately 26km from the Marimaca Oxide Deposit (MOD).

Hole SMD-01 is the first diamond drill hole targeting validation and depth-extension of the reverse circulation (“RC”) drilling. SMD-01 was drilled to a final depth of 950m with assays pending from 600m to the bottom of the hole.

Hole SMR-01 and SMD-01 were drilled approximately 400m north of the known northern extent of the Pampa Medina deposit. SMD-01 was drilled to a final depth of 950m to investigate the potential for repeating manto-mineralized units at depth in primary mineralization. SMD-01 confirms the material extension of the sediment-hosted ‘manto-style’ mineralization. Confirmation of high-grade, oxide manto in the upper part of the sedimentary horizon consistent with Pampa Medina deposit and SMR-01. New zone of manto-style sulphide mineralization identified at depth containing dominantly chalcopyrite-bornite mineralization in deeper, interbedded sandstone and conglomerate units with variable intensity.

Assays pending for 600m-950m will be released to the market when received and validated.

Sergio Rivera, VP Exploration, said, “The scale and intensity of mineralization at Pampa Medina Norte continues to impress us. We now think the system has good potential for stacked mantos which, based on our review of historical drilling data, could be extensive across the broader Sierra De Medina project area.

We are encouraged by the continuation of mineralization at depth, especially the visual bornite and chalcopyrite, These findings also serve to further improve our understanding of the sulphide body which has the potential to be highly accretive to the high-quality overlying oxide leachable manto, where our PEA for the integration into the MOD is progressing.

SMD-02, for which we are currently preparing samples to be assayed, presented a surprise intersection of polymetallic mineralization, which we had not previously considered, but further supports our view that this system has significant ongoing exploration potential.

We are looking forward to updating the market in the near-term on the results from the assays at depth, as well as our additional deep drill holes at Pampa Medina main. Our view remains that we are still in the very early days of the Pampa Medina story and the consolidation of the area has allowed, for the first time, the development of our overall thesis that Pampa Medina and its surroundings represents a single, large scale mineralized system which could be highly complementary to the MOD.”
