Location and accuracy The Kami prospect is at an elevation of about 2,750 feet on a glacier-covered mountaintop about two miles southeast of lake 1410 at the head of Little Kamishak River. This is location 3 of MacKevett and Holloway (1977). The site is in the NE1/4 sec. 14, T. 15 S., R. 32 W., of the Seward Meridian; the location is accurate to within one-quarter mile.

Geologic setting

Geologic description

The Kami prospect consists of chalcopyrite-bearing quartz veins in a roof pendant of sedimentary rocks of the Jurassic Naknek Formation that are above a Tertiary(?) quartz diorite stock. There is little information on the mineralization but there is a geochemical anomaly in copper (values unknown) in stream sediment and rock samples (MacKevett and Holloway, 1977; Cobb, 1980; Church and others, 1992). Bear Creek Mining Company investigated claims in 1971.
