Fish Creek Mine, Fairbanks District, Fairbanks North Star Borough, Alaska, USA

Latitude & Longitude (WGS84): 65° 0' 21'' North , 147° 15' 46'' West
Latitude & Longitude (decimal): 65.00583,-147.26278


Location: Cobb (1972, MF-413), loc. 90; NW1/4 sec. 13, T. 2 N., R. 2 E., of the Fairbanks Meridian. The coordinates mark the middle of an approximate 2-mile-long placered area along Fish Creek.
Geology: Placer mining began in about 1909 where depth to bedrock was about 25 feet. Drift mining from 1909-1916, dredging from 1926 to 1935 (Cobb, 1976; OFR 76-633, p. 66), and dredging from 1940 to 1942 (R.M. Chapman, 1978, U.S.G.S. unpublished memorandum). Two mines on Fish Creek were reported as recently as 1990 (Swainbank and others, 1991). No information on amount of gold production. Most of the dredging appears to have taken place on the bench north of the creek. Stibnite, auriferous bismuth nuggets, cassiterite and scheelite are found in concentrates (Cobb, 1976; OFR 76-633, p. 66).
Workings: Drift mining from 1909 to 1916; dredging from 1926 to 1935 (Cobb, 1976; OFR 76-633, p. 66) Chapman (1978, unpublished U.S.G.S. memorandum) also reported that Dredge no. 7, a wooden hull dredge, worked on Fish Creek above Solo Creek from 1940 to 1942. Two mines on Fish Creek were reported as recently as 1990 (Swainbank and others, 1991).
Production: Drift mining from 1909 to 1916, dredging from 1926 to 1935, and from 1940 to 1942 (Cobb, 1976; OFR 76-633, p.66; R.M. Chapman, 1978, unpublished U.S.G.S. memorandum). No information on amount of gold production.

Commodities (Major) - Au; (Minor) - Bi, Sb, Sn, W
Development Status: Yes; small
