Location: This prospect is at an elevation of about 5,300 feet at the head of Slide Creek. The map site is about 1.3 mile due east of VABM 6463 (Art), in the SE1/4 of sec. 7, T. 11 S., R. 2 E., of the Fairbanks Meridian. The location is accurate to within 1.5 miles.
Geology: The country rocks at this prospect are the Lower Mississippian to Middle Devonian Totatlanika Schist, composed predominantly of mafic and felsic metavolcanic and metavolcaniclastic rocks (Wilson and others, 1998). The deposit consists of massive-sulfide lenses in schist. The lenses are chiefly galena and sphalerite, accompanied by quartz and sericite. The footwall schist is altered to chlorite and sericite.
Workings: There reportedly has been surface exploration and possibly limited drilling.
Age: Mineralization was probably syngenetic with the Lower Mississippian to Middle Devonian host rocks.
Alteration: Footwall schist is altered to chlorite and sericite.

Commodities (Major) - Ag, Pb, Zn; (Minor) - Au, Cu
Development Status: None
Deposit Model: Kuroko massive sulfide (Cox and Singer, 1986; model 28a)
