Location and accuracy This site is located on the east side of Amook Bay in sec. 29, T. 31 S., R. 28 W., of the Seward Meridian (Martin, 1913, locality 7; Berg and Cobb, 1967, figure 15, locality 12; Cobb, 1972, MF460, locality 2; McGee, 1972, locality 9; MacKevett and Holloway, 1977, locality 2). Site location is accurate to within a few hundred feet.

Geologic setting

Geologic description

At this site auriferous quartz veins cut Cretaceous slate. The main vein worked by Amok Gold Mining Company strikes N. 45 W. and dips 80 southwest and averages 3 feet in thickness with a maximum of 5 feet. The vein consists of quartz and minor pyrite. Quartz veinlets, most of which parallel the slaty cleavage, are present in the surrounding slates. A sill-like body of keratophyre is present at the site. Capps (1937) reports that only a few hundred dollars worth of gold was produced.

Production and reserves

Workings or exploration This property was developed by a 210-foot adit, a 130-foot shaft, and 180 feet of drifts. A 5-stamp mill, erected in 1906, burned and was replaced by a 10-stamp mill. Mining ceased in 1913 but was resumed for a time in 1927-28. The latter endeavor failed because the ore was too low in grade.
Indication of production Yes; small
Production notes Total production is said to have been worth only a few hundred dollars.
