Reference information

Comments Copper mineralization is hosted by the Tarahumara Formation (andesitic volcanic breccias, flows, volcaniclastic sandstone, conglomerate. In 2007, Cerro Verde was at an early stage of development (inferred resources of 81 Mt at 0.35% Cu); the other two areas are exploration targets. Interpreted as an IOCG deposit in Laramide intermediate-to-felsic volcanic rocks (Constellation Copper Corp., 2007). Alteration: unknown.
