Location: Location plotted is in center of area containing samples 30, 60-61 of Jansons (1982, p. 17) and Jansons and Baggs (1980, p. 33), and samples WK109, WK112, and WK116 of Nokleberg and Winkler (1982, Pl. 2); in T10S, R29W; along west bank of Drenchwater Creek about 3.5 mi (5.6 km) upstream from the confluence of False Wager Creek; within 2000 ft (610 m).
Geology: 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.
Workings: 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).
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.
