(“Marimaca Copper” or the “Company”\n \n\n (TSX: MARI)\n \n is pleased to announce results from the re-interpretation of data in the Pampa Medina Project Area (\n \n “Pampa Medina”\n \n ) which incorporates the Pampa Medina and Madrugador deposits and the newly identified Pampa West oxide zone, and is located approximately 25km from the Company’s flagship Marimaca Oxide Deposit (“\n \n MOD\n \n ”).\n \n\n The Company also announces results from five broad reconnaissance exploration holes, which were designed to identify the limits of the mineralized horizon. This drilling, when combined with the full review and relogging of historical drilling, shows consistent broad zones of oxide copper mineralization of variable grades in the same stratigraphic horizon over an area of approximately 5km by 4km, which is the current defined extent of the manto horizon. Potential exists for further extensions in all directions, with ongoing step out programs.\n \n\n Based on the extensive work completed, including the new drilling results extending Pampa Medina, the Company believes that Pampa Medina may be the central part of a larger manto system, which genetically links the Madrugador, Pampa Medina, Sierra Valenzuela (Antofagasta Minerals) and Pampa Norte deposits. It was this interpretation which led to the discovery of the new, shallow, oxide opportunity at Pampa West. Based on these results, the Company will continue with its strategy of large-scale step-out holes from known mineralization, and deep sulphide-target drilling to try to identify the limits of the system.\n \n\n Marimaca is considering alternatives for a significantly expanded program for the balance of 2025 to include both reverse circulation (“RC”) and diamond drilling. The objectives of this program will be to continue to step out to identify the limits of the system, to test the deeper units for primary copper mineralization and to delineate areas for potential extensions of near-surface oxide mineralization.\n \n\n\n\n Sergio Rivera, VP Exploration, commented:\n \n\n\n\n\n “Our extensive revie...
