Reference information

Comments Resources: 4 Mt at 0.4% Cu and 2 to 3 g/t Au. Lies 5 km southeast of the Tahonas prospect, probably related to the intrusive system. A large area of advanced argillic alteration resembles the nearby El Sauzal mine (Goldcorp, 2 MM oz gold). Only a small part of the area has been previously explored in detail (EXMIN Resources, Inc, 2008). Alteration: propylitization-silicification.
