Location: This site represents several prospects in about a 6-square-mile area about 5 miles northwest of the Mauneluk River. The coordinates are for the center of the area in sec. 29, T. 20 N., R. 14 E., Kateel River Meridian. Acurracy of location is 2000 ft. The site includes localities 59 and 60 of Grybeck and Nelson (1981).
Geology: The BTcc group of prospects explore silver-base metal volcanogenic massive sulfide deposits in a sequence of low to medium grade, metamorphosed basaltic and rhyolitic rocks, submarine ash flow tuffs, and pelitic and carbonaceous sedimentary rocks known as the Ambler schist belt. The deposits are Devonian or Mississippian based on fossil evidence and U-Pb radiometric dating (Hitzman, 1978; Hitzman and others, 1986). There are numerous prospect pits and diamond drill sites in the area dating to the late 1970's. Surface mapping has shown that the deposits extend 10 km to the west along the same stratigraphic horizon.
Workings: Surface mapping and drilling.
Age: Syngenetic deposit in Devonian or Mississippian host rocks (Hitzman and others, 1986).
Commodities (Major) - Ag, Cu, Pb, Zn; (Minor) - Ba
Development Status: None
Deposit Model: Kuroko massive sulfide (Cox and Singer, 1986; model 28a)
