|Location and accuracy||This occurrence is located at an elevation of approximately 4,300 feet in the mountains south of lower Butte Creek, and 0.75 mile south of VABM 5896 (Way). The map site is near the south and of the west boundary of sec. 7, T. 22 S., on the boundary of R. 1 W., and R. 1 E., of the Fairbanks Meridian. The location is accurate to within 1,000 feet.|
Geologic descriptionThe area of this occurrence is underlain by a 2,00-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.
