|Location and accuracy||This occurrence is located on the Alaska Peninsula on the east shore of upper American Bay. It is in the SE1/4 of sec. 29, T. 51 S., R. 70 W., of the Seward Meridian. This site is referred to as PMRGX-14 in Wilson and others (1988, locality 63). The location is accurate to within 1,200 feet.|
Geologic descriptionThis occurrence consists of a 3-inch vein of fine-grained, massive sulfides in andesite that intrudes sedimentary units of the Paleocene to Eocene Tolstoi Formation (Wilson and others, 1995). The locality is approximately 2,500 feet southeast of the contact of the American Bay batholith. One rock sample collected by the U.S. Geological Survey in the mid-1980s was reported to be anomalous in antimony, arsenic, copper, lead, silver, tin, and zinc (Wilson and others, 1988).
