(“Marimaca Copper” or the “Company”)\n \n\n (TSX:MARI, ASX:MC2)\n \n is pleased to announce significant, high grade, sediment-hosted copper sulphide and oxide intersections which materially extend the Pampa Medina deposit in all directions. Pampa Medina is located at low altitude approximately 28km east of the Company’s Marimaca Oxide Deposit (“MOD”) in a flat “pampa” valley within the Atacama Desert (Figure 1). Drilling targeted extensions of the shallow oxide-chalcocite mineralization at Pampa Medina and intersected ultra high-grade, bornite-chalcopyrite, disseminated chalcopyrite and high-grade oxide mineralization, which is hosted in a regionally extensive system of interbedded sedimentary rocks hosting the Pampa Medina deposit.\n \n\n\n The Company will host an investor presentation, covering today’s announcement, via the Investor Meet Company (“IMC”) platform on July 8, 2025. Further details can be found below.\n \n\n\n\n Highlights\n \n\n\n\n\n Drilling confirms Pampa Medina is part of a significant, flat lying, sediment hosted (stratiform) manto system, unique in Chile, that appears more analogous to the Kupfershiefer or African sediment hosted Cu deposits\n \n\n\n\n Thick (>15m true thickness), ultra high grade (>5% CuT) zones identified more than 600m apart in the same lithological horizon between SMRD-13 and SMR-01\n \n\n\n\n High-grade (>1.0% CuT), sedimentary-hosted copper mineralization defined by diamond drilling across a 600m east-west x 1,000m north-south area, with further drilling intersections indicating potential extensions to 1.4km x 1.2km\n \n\n\n\n Ultra high-grade bornite and chalcopyrite manto zones east, immediately down-dip, of Pampa Medina Deposit\n \n\n\n\n Highest grades correspond to interbedded shales, sandstones, conglomerates and tuffs\n \n\n\n\n Complements previous ultra high-grade zone encountered in SMR-01\n \n\n\n\n\n\n Hole SMRD-13 (true widths estimated to be 95% of reported intersection):\n \n\n\n\n 6m of 12.0% Cu from 594m downhole wi...
