Location and accuracy The Gold King Creek mine is mostly in sec. 6, T. 10 S., R. 2 W., Fairbanks Meridian. Gold King Creek is a north-flowing tributary of the Wood River. The mine is localities 80, 81, and 82 of Cobb (1972 [MF 410]).

Geologic setting

Geologic description

In 1990 and 1991, Gold King Creek was the largest placer mine in the district (Swainbank and others, 1991, p. 31; Bundtzen and others, 1991, p. 34). Gold is believed to be derived from the Tertiary Nenana Gravel (Bundtzen and others, 1991, p. 34). Placer gold is found in both the 4 to 5 feet of gravel overlying bedrock and on the clay-rich bedrock (Prindle, 1907, p. 212). Mining took place intermittently from 1903 to 1940 (Cobb, 1976 [OFR 76-662, p. 44]). In the 1920s, an attempt at large-scale hydraulic mining of Nenana Gravel was not financially successful (Capps, 1924, p. 138). The gold varies from 818 to 833 fine (Glover, 1950).

Production and reserves

Workings or exploration In 1990 and 1991, Gold King Creek was the largest placer mine in the district; it operated under the direction of Warren Taylor and Alaska Unlimited Inc. (Swainbank and others, 1991, p. 31; Bundtzen and others, 1991, p. 34). Mining from 1903 to 1916 was done by open-cut, pick-and-shovel methods and continued intermittently until 1940 (Maddren, 1918, p. 401). In 1924, a hydraulic operation was active in gravels 6 to 7 feet in depth (Wimmler, 1924, p. 43). An attempt at large-scale hydraulic mining of the Nenana Gravel was not financially successful (Capps, 1924, p. 138). This failed attempt consisted of 11 miles of ditches designed to convey 3,000 miner's inches of water from the upper part of Gold King Creek to a point on the eastern slopes of the valley, where it was to be delivered to a pipeline with a head of 700 feet (Maddren, 1918, p. 401).
Indication of production Yes; small
