Location: The Homestake mine is located in sec. 33, T. 10 S., R. 5 W., Fairbanks Meridian. Placer mining on Homestake Creek, in the Fairbanks quadrangle, took place along the lower mile of the creek. However, most mining took place upstream in the Healy quadrangle. Homestake Creek is a tributary of the Totatlanika River and is about 10 miles east-southeast of the Liberty Bell mine. This mine is locality 74 of Cobb (1972 [MF410]).
Geology: Homestake Creek was one of the most important gold-producing creeks in the Totatlanika basin. The upper part of the basin, in the Healy quadrangle, is underlain by sand, clay, gravel, and lignitic coal (Capps, 1912). The stream then flows through a ridge of schist that has been intruded by andesite (Capps, 1912; Wahrhaftig, 1970 [GQ-810]). In 1912, placer operations were in and immediately upstream of the canyon where gold was first discovered near the mouth of Fox Gulch in the Healy quadrangle (Capps, 1912; Maddren, 1918). The richest placers are below a zone that contains many quartz veins in carbonaceous slate (Maddren, 1918). Gravels are generally 6 feet deep on decayed schist bedrock. The gold is rusty and rather coarse; it is found mainly in the top foot of schist bedrock (Capps, 1912). The gold varies from 833 to 842 fine (Glover, 1950).
Workings: Small-scale mining occurred from 1905 to 1909 and in 1912, 1935, 1936, and 1939 (Cobb, 1976 [OFR 76-662, p. 73]).
Age: Quaternary placer.
Production: About 3,870 ounces of gold was produced from 1905 to 1909 (Maddren, 1918). There is no information available of the amount of production in subsequent years.
