Location and accuracy The Pearl Creek mine is located in sections 15 and 22, T. 2 N., R. 2 E., Fairbanks Meridian. Pearl Creek has been placer mined above its mouth on Fish Creek. The area is approximately 2 miles east-northeast of Gilmore Dome, and the mine tailings are marked on the Fairbanks D-1 topographic map. The coordinates given are for the approximate center of this activity. Another area of placer mining is a 0.5-mile stretch near the junction of Yellow Pup Creek (FB0121) and Pearl Creek; this mine is also shown on the Fairbanks D-1 quadrangle. The mine is locality 59 of Cobb (1972 [MF 410]).

Geologic setting

Geologic description

Pearl Creek drains an area predominantly underlain by Cretaceous granite that has intruded the Fairbanks Schist (Newberry and others, 1996). Placer gold was mined along Pearl Creek from 1911 to 1914, from 1938 to 1940, and in recent years, as evidenced by the relatively fresh tailings near its confluence with Fish Creek (Cobb, 1976 [OFR 76-662, p. 109]). Abundant scheelite, wolframite, and native bismuth have been found in concentrates.

Production and reserves

Workings or exploration Placer gold was mined along Pearl Creek from 1911 to 1914, from 1938 to 1940, and in recent years, as evidenced by the relatively fresh tailings near its confluence with Fish Creek (Chapman and Foster, 1969; Cobb, 1976 [OFR 76-662, p. 109]).
Indication of production Yes; small
Production notes Placer gold was mined, but production figures are not available.
