Barry Arm

The Barry Arm 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.

Ore: Stibnite

Comments

Comment (Production): Production Notes = Approximately 1,000 lbs of stibnite ore taken out before 1910 (Grant and Higgins, 1910).

Comment (Deposit): Model Name = Simple Sb deposits (Cox and Singer, 1986; model 27d)

Comment (Deposit): Other Comments = Possibility of a gold-bearing quartz vein about 5 miles from mouth of Barry Arm and 1 mile inland reported by Johnson (1918).

Comment (Exploration): Status = Inactive

Comment (Workings): Workings / Exploration = Development restricted to surface stripping and trenching.

Comment (Geology): Geologic Description = A zone of brecciated slate is present along a thrust fault that strikes N 68 E, and dips 45-65 N, in Cretaceous slate (Grant and Higgins, 1910). The 6 to 8 ft zone of brecciated slate is cemented by quartz and contains a layer, 1 to 8 inches thick of finely columnar and granular masses of stibnite with associated acicular stibnite crystals and quartz (Brooks, 1916). Stibnite accounts for as much as 1/3 of the mass locally. Ferruginous carbonate is intimately associated with the stibnite. Grant and Higgins (1910) report specimens indicate that the quartz vein was shattered and subsequently intruded by stibnite-bearing solutions. Bedrock is Late Cretaceous Valdez Group metasedimentary rocks.

Comment (Geology): Age = Late Cretaceous or younger; vein cuts Late Cretaceous Valdez Group metasedimentary rocks.

Comment (Reference): Primary Reference = Grant and Higgins, 1910
