Location: This occurrence is at an elevation of about 4,100 feet on the south wall of the valley of lower Butte Creek. The map site is about 1.2 miles northwest of VABM 5896 (Way), in the NW1/4 of sec. 1, T. 22 S., R. 1 W., of the Fairbanks Meridian. The location is accurate to within 1000 feet. This is location 36 of Clark and Cobb (1972).
Geology: The area of this occurrence is ubderlain by Middle or Upper Triassic Nikoli Greenstone, Middle Triassic to Upper Pennsylvanian metasedimentary rocks, and numerous diabasic and gabbroic dikes and sills (Wilson and others, 1998). The occurrence is near a thrust fault that separates the two bedded units, and consists of pyrite and chalcopyrite disseminated in the metasedimentary rocks (Saunders, 1961).
Workings: Surface sampling only.
Age: The sulfide minerals probably are syngenetic with their Triassic-Upper Pennsylvanian host rocks.
Commodities (Major) - Cu
Development Status: None
Deposit Model: Cyprus massive sulfide (Cox and Singer, 1986; model 24a)
