The Raspberry Beach is a gold 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 (Geology): Geologic Description = This site was first mentioned by Brooks (1915, p. 47) who reported that low grade placer gold had been found on Raspberry Island. The latest reported activity took place in 1935. The deposition of beach placer gold is thought to have resulted from the reworking of coastal deposits of glacial gravels and tills.

Comment (Deposit): Model Name = Gold placer (Cox and Singer, 1986; model 39a).

Comment (Reference): Primary Reference = Capps, 1937

Comment (Workings): Workings / Exploration = In 1935 it was reported that 2 or 3 men were prospecting and mining here. Some drilling was done on valley gravels located between Raspberry Beach and Onion Bay to test the viability of a dredge operation (Capps, 1937, p. 172). Results were apparently poor and the drill project was abandoned.

Comment (Production): Production Notes = A small amount of gold was produced but no records are available.

Comment (Geology): Age = Quaternary
