Location: This occurrence is on the ridge between lower Iron Creek (SO127) and the West Branch of Sherrette Creek (SO129), at an elevation of 950 feet. It was originally located by Asher (1969, DGGS R18, Figure 2). It is locality 5 of Cobb (1972, MF 445; 1978, OF 78-181).
Geology: Asher (1869, DGGS R18) reported surface float of finely crystalline galena in quartz at this locality. Briskey (1983) identified stringers and disseminations of chalcopyrite and malachite in schist and in quartz bands in schist here. Bedrock is part of a lower Paleozoic metasedimentary assemblage (Till and others, 1986).
Workings: No exploration activities are known for this locality.
Alteration: Oxidation and silicification.
Commodities (Major) - Cu, Pb
Development Status: None
Deposit Model: Chalcopyrite and galena in quartz-rich rocks.
