Comments
Comment (Exploration): Status = Inactive
Comment (Geology): Age = K-Ar ages of 319+10 and 330+17 Ma were obtained from biotite from a volcanic interbed within the mineralized belt; a Pb-isotope model age of 200 Ma was obtained from galena.
Comment (Deposit): Model Name = Lode; sediment-hosted Pb-Zn
Comment (Geology): Geologic Description = Sulfides occur as disseminated grains, fracture fillings, and in boxwork quartz in black chert and siliceous shale of Mississippian to Lower Pennsylvanian(?) Kuna Formation of Lisburne Group; felsic to intermediate(?) volcanic rocks are interbedded in the sedimentary section. The sulfides are at the west end of a west-northwest-trending zone of sporadic occurrences that extends about 1.25 mi (2 km) parallel to the strike of bedding and complex structural imbrication. Sulfides probably syngenetic.
Comment (Reference): Primary Reference = Nokleberg and Winkler (1982)
Comment (Workings): Workings / Exploration = Some samples contain up to 23% Zn, 5.1% ppm Pb, 1150 ppm Cu, 5000 ppm Ba, and 15 ppm Ag (Jansons, 1982, p. 22-28; Jansons and Baggs, 1980, p. 40-46).
