|Location and accuracy||This occurrence is at an elevation of about 4,500 feet, on a north-south ridge north of, and perpendicular to, upper Schist Creek. The map site is in the NW1/4 of sec. 1, T. 17 S., R. 6 W., of the Fairbanks Meridian. The location is accurate to within 1500 feet. This is location 9 of Clark and Cobb (1972).|
Geologic descriptionThe country rocks in the area of this occurrence are the Paleocene Cantwell Formation which consists of terrigenous sedimentary rocks, including a few thin coal beds, and Eocene-Oligocene granitic plutons that intrude the Cantwell (Wilson and others, 1998). The occurrence consists of unspecified copper, molybdenum and silver minerals in the granitic rocks (Clark and Cobb, 1972).
