|Location and accuracy||This occurrence is located on the Alaska Peninsula about 1.7 miles north of Anchor Bay, and 0.45 mile west-southwest of the top of hill 1325 (MacKevett and Holloway, 1977, locality 8; Wilson and others, 1988, locality 8). The location is accurate to within 1 mile.|
Geologic descriptionThe country rocks at this occurrence are sedimentary units of the Paleocene to Eocene Tolstoy Formation (Wilson and others, 1995). The occurrence is described by MacKevett and Holloway (1977) as an altered zone associated with Tertiary granitic rocks. U.S. Geological Survey mapping in the mid-1980s does not show granitic plutons in this area (Wilson and others, 1988). Samples of sedimentary rock collected in this area by the U.S. Geological Survey in the mid-1980s contained as much as 20 ppm copper, 20 ppm lead, and 80 ppm zinc (Angeloni and others, 1985).
