Location: This prospect is at an elevation of about 3600 feet on a ridge 5 miles north of Avaraart Lake. It is in sec. 23, T. 20. N., R. 14 E., of the Kateel River Meridian. The location is and accurate to within 1000 ft. The site corresponds to locality 61 of Grybeck and Nelson (1981).
Geology: This prospect explores a silver-basemetal 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 deposit is Devonian or Mississippian in age, based on fossil evidence and U-Pb radiometric dating (Hitzman and others, 1986). Numerous copper-stained zones in the schists have been explored by prospect pits and several diamond drill holes. The deposit is similar to, and probably an extension of, the deposits at SP032.
Workings: The deposit has been explored by a number of prospect pits and several diamond drill holes.
Age: Syngenetic massive sulfide deposit in Devonian or Mississippian host rocks.
Alteration: Locally prominent copper-staining.
Commodities (Major) - Ag, Cu, Pb, Zn
Development Status: None
Deposit Model: Kuroko massive sulfide (Cox and Singer, 1986; model 28a)
