Marimaca Extends Pampa Medina Norte Discovery – Intersects 68m at 1.20% and 40m at 1.07% CuT in Dominantly Oxides with Assays Pending for Deep Sulphide Extension

Core Insights - Marimaca Copper Corp. announced further drilling results at Pampa Medina Norte, indicating significant mineralization potential in the northern extension of the Pampa Medina Deposit [1][2] - The drilling results from hole SMD-01 show high-grade copper intersections, confirming the extension of the sediment-hosted manto-style mineralization [6][11] - The exploration team is optimistic about the potential for stacked mantos and the integration of these findings into the Marimaca Oxide Deposit (MOD) [4][5] Drilling Results - Hole SMD-01 was drilled to a depth of 950m, with significant intersections including 242m at 0.65% CuT from 252m, and higher grades of 1.20% CuT over 68m from 298m [6][14] - The upper section of SMD-01 validated previous reverse circulation drilling results, confirming the presence of high-grade oxide manto [6][11] - Assays are pending for the lower section of SMD-01 from 600m to 950m, which will provide further insights into the mineralization at depth [6][7] Geological Context - Pampa Medina is characterized as a manto-style copper deposit hosted in Jurassic-Triassic sedimentary units, with copper primarily found in oxide and sulphide forms [9][33] - The mineralization at Pampa Medina Norte includes visual bornite and chalcopyrite, indicating a transition to primary sulphides at greater depths [10][11] - Historical drilling at Pampa Medina was limited to 400m, suggesting that deeper drilling may reveal more extensive mineralization [11][10] Future Exploration Plans - The company plans to continue exploration at Pampa Medina, including additional deep diamond drill holes to assess the potential for further mineralization extensions [6][8] - SMD-02, another drill hole, has shown unexpected polymetallic mineralization, indicating further exploration potential in the area [7][8] - The overall strategy is to consolidate the understanding of the Pampa Medina system and its potential to complement the MOD [8][4]
