Location: This occurrence is at an elevation of about 4,000 feet, 1.5 miles south of VABM 5896 (Way). The map site is in the SE1/4 of sec. 13, T. 22 S., R. 1 W., of the Fairbanks Meridian. The location is accurate to within 1,000 feet. This is location 38 of Clark and Cobb (1972).
Geology: The country rocks in the area of this occurrence consist of a 2,000-meter-thick sequence of Lower Permian? and Pennsylvanian, massive volcanic flows, breccias, and subordinate volcaniclastic rocks, all largely andesitic in composition (Wilson and others, 1998). The occurrence consists of pyrite and chalcopyrite disseminated in the volcanic rocks.
Workings: Surface sampling only.
Age: The sulfide minerals probably are syngenetic with their Lower Permian - Pennsylvanian host rocks.
Commodities (Major) - Cu
Development Status: None
Deposit Model: Cyprus massive sulfide (Cox and Singer, 1986; model 24a)
