Location: Cobb (1972, MF-413), loc. 47; NW1/4NW1/4 sec. 22, T. 3 N., R. 2 E., of the Fairbanks Meridian. This location is a shaft at the head of the west fork of Too Much Gold Creek, a little below the summit of the divide to Wolf Creek, at an elevation of 2,250 feet. Accuracy is within 1,000 feet.
Geology: This site consists of a quartz vein containing arsenopyrite, jamesonite, and galena, in quartz-mica schist (Hill, 1933, p. 104). The vein strikes N 60 W and dips 70 S.
Workings: Workings consisted of a shaft, tunnel and surface pits. In 1931, the shaft was iced up and the tunnel caved at the mouth. The surface pits on the divide to the NW were also inaccessible (Hill, 1933).
Production: Mined by McNeil and Huddelson in 1915, but no record of production (Smith, 1917; BMB 142, p.23). Antimony ore may have been mined (Killeen and Mertie, 1951, p. 14).
Commodities (Major) - Sb; (Minor) - Pb
Development Status: Undetermined
Deposit Model: Polymetallic quartz vein.
