Location: This occurrence is at an elevation of about 2,250 feet, approximately 2.7 miles west-northwest of VABM Circle and 4.2 miles west of the junction of Rice Gulch Creek and the Salmon Fork of Black River. It is in T. 19 N., R. 30 E., of the Fairbanks Meridian. The location is accurate to within 500 feet.
Geology: The general area of this occurrence is underlain mainly by undivided Lower Cambrian and Proterozic rocks of the Tindir Group, which consists predominantly of carbonate, quartzite, argillite, and subordinate volcanic rocks (Dover, 1994). Geologic mapping by Doyon Limited (1987) delineated a small ultramafic body at the western end of a ridge of quartzite and phyllite. The ultramafic body contains minor chalcopyrite and asbestos. The asbestos occurs in 2-inch- to 5-inch-wide veins. Limited outcrop of the ultramafic body did not allow an accurate determination of the density and extent of the asbestos veins. Quartz veins in the ultramafic body contain chalcopyrite (Doyon Limited, 1987).
Commodities (Major) - Asbestos, Cu
Development Status: None
Deposit Model: Asbestos and chalcopyrite associated with a small ultramafic body.
