News Release 13-10
October 9, 2013 - Marimaca Copper Corp. (“Coro” or the “Company”) (TSX Symbol: COP) is pleased to announce that its subsidiary, Minera Marimaca CopperChile Ltda. (“MCC”) signed on October 4, 2013 an agreement with Minera Aurex (Chile) Limitada (“Aurex”), an indirect subsidiary of Freeport-McMoRan Copper & Gold Inc. (“Freeport”), whereby Aurex may exercise an option to acquire an interest in the Payen property. The property is located approximately 90km NNE of La Serena, 4km W of the Panamerican Highway and approximately 47km from the coast, in the III Region of Chile, at an elevation of 1,100m (Figure 1).
Alan Stephens, President and CEO of Marimaca Coppercommented, “Payen has the potential to host a major copper-gold porphyry deposit, and we look forward to seeing the results of the Aurex exploration program over the coming years. Marimaca Copperremains focussed on advancing its Berta heap leach copper project to production, in conjunction with its partner, ProPipe S.A., and in further exploring its exciting El Desesperado porphyry copper project, located in the Chuquicamata district.”
The large NE-SW oriented Pajonales alteration zone is located in the same 90-110 million year old belt of porphyry copper-gold deposits as Teck’s Andacollo mine, Cemin’s Dos Amigos mine, PanAust’s Inca de Oro & Carmen projects and Hot Chili’s Frontera project, which is located some 2.5km SE of the Payen property boundary.
The Payen property is located in the Pajonales alteration zone, where it is at its widest, and where the alteration appears most intense. The northern end of the property is transected by a NW fault which has uplifted to the north and exposed a potassically altered and quartz stockworked diorite porphyry with associated copper-gold mineralization. This has been subjected to reverse circulation drilling carried out by the property owner in 2009, and diamond drilling completed by a private Chilean company in 2011-2012. Results of this drilling were summarized in the Company’s news release of October 17th 2012.
This mineralization is associated with a magnetic high anomaly, and Coro’s exploration has shown that several other similar mag highs are present on the property, coinciding with outcropping mineralized diorite porphyry stocks. Much of the remainder of the property hosts extensive phyllic alteration with outcropping leached cap, quartz stockworking, remnant copper oxides, and associated magnetic low and copper geochemical anomalies. High sulphidation alteration, including phreatomagmatic breccias and silicified ledges with anomalous gold, indicative of a remnant lithocap are exposed at the highest elevations. Previous geochemical sampling has indicated the presence of strongly anomalous copper associated with certain areas of the phyllic alteration, which Marimaca Copperbelieves have good potential to host chalcocite enrichment.
