Location: Cobb (1972, MF-413), loc. 2; NW1/4SW1/4 sec. 1, T. 6 N., R. 10 W., of the Fairbanks Meridian. This deposit is on Sawtooth Mountain. It is marked on the Livengood (B-6) quadrangle by a trail up Buckeye Creek from the landing strip to the saddle on Sawtooth Mountain.

Geology: Massive stibnite occurs as a vertical cylinder about 3 meters wide. It is hosted in argillite of Jurassic or Cretaceous flysch near a contact with Cretaceous granitic rock (Nokleberg and others, 1987; R. M. Chapman, written commun., 1985). The granitic rock has been K-Ar dated at 88.3 m.y. Grab samples from the dump have up to 46.2% Sb, 0.7 grams/ton Au and 15.1 grams/ton Ag (Nokleberg and others, 1987).

Workings: A shaft reached a depth of 83 feet (Saunders, 1958; ATDM PE 49-14).

Production: The vein produced 590 tonnes of ore with 58% stibnite through 1970, with minor production in 1984 and 1985 (Nokleberg, 1987, p. 32).

Commodities (Major): - Sb; (Minor) - Ag, Au

Development Status: Yes; small

Deposit Model: Stibnite vein (Cox and Singer, 1986; model 27d).
