|Location and accuracy||This occurrence is on the south wall of the Susitna River at an elevation of about 1,700 feet. It is about 2 miles southwest of the junction of Devil Creek and the Susitna River, about 0.3 mile west-southwest of the center of sec. 4, T. 31 N., R. 2 E., Seward Meridian. The location is accurate.|
Geologic descriptionThe rocks in the vicinity of this occurrence are granodiorite, migmatite, gneiss, and schist (Csejtey and others, 1978). An eroded dike cuts the gneiss at one location (Kurtak and others, 1992). A sample of quartz-rich gneiss contains 13.5 parts per million silver, 2,882 parts per million copper, and 302 parts per million zinc (Balen, 1990). A float sample of sulfide-bearing schist contains 10.5 parts per million silver, 180 parts per million arsenic, 264 parts per million lead, and 2,121 parts per million zinc.
