Reference information

Comments Grab samples: up to 0.8% Cu, 6 g/t Au and 600 g/t Ag. Exposed. Breccia, quartz monzonite porphyry, skarn. Prospects in this area may all be IOCGs, ~ 65 Ma generally, older Laramide likely. Area is permissive, but not as highly prospective as N Laramide tracts (Lukas Zürcher, oral comment, 2008). Fe prospects within a few km.
