Part of Yale Resources 2,620-hectare La Verde Project that on 6 contiguous exploration concessions (Yale Resources Ltd., 2008). Tentatively classified as a porphyry system based on geology (Lukas Zürcher, oral commun., 2008). Epidote-garnet tactite with scheelite, powellite, and oxide copper minerals. Development: W-bearing tactite discovered in the district in 1943. Three claims recorded: El Nublado, El Picacho, and La Florencia. Minor development (shallow pit),but no tungsten ore mined; gold produced at El Picacho and La Florencia. Geology: NW-strinking belt of discontinuous tactite outcropus surrounded by metalimestone and hornfel, probably underliain by granite. Granite crops out 200 m W of the limestone, separated from it by silicified volcanic breccia in contact with limestone along a pre-intrusive fault.
