Location: This prospect is at an elevation of about 4,900 feet on the south side of the drainage basin at the head of Kansas Creek, approximately 8 miles upstream from its mouth on the Wood River. It is approximately 2 miles southeast of VABM 7437 (Al). The map site is in sec. 19, T. 12 S., R. 1 E., of the Fairbanks Meridian. The location is accurate to within 1 mile. This is location 5 of Clark and Cobb (1972) and location 15 of Cox and others (1989).
Geology: This prospect is in the Lower Paleozoic or possibly Late Precambrian Birch Creek Schist, which consists of quartz-sericite schist, quartzite, and a few interbeds of massive marble (Wilson and others, 1998). Lower Tertiary and Upper Cretaceous granites intrude the metasedimentary rocks less than one mile to the south. The deposit consists of quartz lenses containing stibnite, minor galena, and sphalerite. The lenses are up to 6 feet thick and trend northeast. Samples contain as much as 63% antimony (Joesting, 1943).
Workings: Only surface workings. Samples contain as much as 63% antimony (Joesting, 1943).
Age: Probably Late Cretaceous or younger, assuming deposit is related to nearby granitic intrusive rocks.
Commodities (Major) - Pb, Sb, Zn
Development Status: None
