The Sawtooth Mountain is a antimony mine located in Alaska.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Exploration): Status = Inactive

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

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

Comment (Geology): Geologic Description = Massive stibnite occurs as a vertical cylinder about 3 m 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 g/ton Au and 15.1 g/ton Ag (Nokleberg and others, 1987). The vein produced 590 tonnes of ore with 58% stibnite through 1970, with minor production in 1984 and 1985.

Comment (Reference): Primary Reference = Nokleberg and others, 1987

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