|Location and accuracy||This site is the approximate center of block of four lode claims staked in 1977 about two miles south of Indian Point on southern Kupreanof Island. This site is near the center of section 26, T. 59 S., R. 77 E.|
Geologic descriptionThis site is the near the center of a block of four lode claims staked in 1977 and active through 1978 (U.S. Bureau of Mines, 1980). The site was examined by Still and others (2002) who found a 0.15-foot thick band of pyrite along the foliation of sericite schist. Samples contained up to 187 parts per billion gold. The rocks in the area are part of a Mesozoic phyllite and slate unit (Brew, 1997).
