The Puale Bay is a copper 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 (Reference): Primary Reference = Berg and Cobb, 1967

Comment (Workings): Workings / Exploration = Samples collected and analyzed.

Comment (Deposit): Other Comments = This site is located within Becharof Natural Wildlife Refuge.

Comment (Geology): Geologic Description = Berg and Cobb (1967, p. 7) report that in 1920 samples were collected from chalcopyrite lenses which could be traced for 1 mile. Two samples assayed up to 0.31 ounce per ton gold, 8.1 ounces per ton silver, and 24.4 percent copper. Bedrock in this area consists of Upper Jurassic to Lower Cretaceous sedimentary units of the Naknek formation. The deposit type is unknown but may be a polymetallic vein controlled by a contact zone of an unmapped dike or sill.

Comment (Deposit): Model Name = Polymetallic vein ? (Cox and Singer, 1986; model 22c).
