Location: Location plotted is area of samples NK4b,4d; NK13d-g; and MD116 of Nokleberg and Winkler (1982, Pl. 2); in T10S, R29W; about 0.5 mi (0.8 km) east of Drenchwater Creek and 3 mi (4.8 km) upstream from 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 the Lisburne Group; an interbed of felsic to intermediate(?) volcanic rocks occurs nearby. These sulfides are about midway in a west-northwest-trending zone of sporadic occurrences that extends about 1.25 mi (2 km) parallel to the strike of bedding. The sulfides are probably syngenetic.
Workings: Samples contain as much as >10,000 ppm Zn, 20,000 ppm Pb, 1500 ppm Ba, and 150 ppm Ag (Nokleberg and Winkler, 1982, p. 16).
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.
