Reference information

Comments Cu-Au porphyry target (Ross River Minerals, Inc., 2008; Reeves, 2005). Mineralized outcrops along creek banks and canyon walls; disseminated copper and Cu-Mo-tourmaline breccia. Grab samples of 10 outcrops: 0.37% Cu, 14.66 ppm Mo, 0.11 g/t Au, and16 g/t Ag. No resources or reserves. Four Cu-Au porphyry targets associated with Sinaoloa batholith: (1) La Langosta/El Bagre Cu-Au porphyry target defind by soil Cu anomaly (disseminated chalcopyrite in potassically altered malachite-stained rock), (2) Cerro Colorado target based on soil and IP (fracture-controlled and disseminated chalcopyrite in potassically altered granodiorite), (3) La Cetolla target 1.5 km NE of La Langosta previously explored in 1970s, and (4) Jocquistes.
