The Cape Alitak 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 (Workings): Workings / Exploration = As reported by Capps (1937), in 1935 a mill was under construction to treat the wind-blown dune sand for its gold content. No further efforts were reported and the endeavor was apparently not sucessful. At this same time some mining of the beach deposits was being carried out with sluice boxes and amalgamation plates.
Comment (Exploration): Status = Inactive
Comment (Reference): Primary Reference = Capps, 1937
Comment (Deposit): Model Name = Gold placer (Cox and Singer, 1986; model 39a).
Comment (Deposit): Other Comments = This site is located within the Kodiak National Wildlife Refuge.
Comment (Geology): Geologic Description = At this site placer gold has been found in beach deposits as well as in sand dunes derived from the beach sands. Magnetite is fairly abundant in the dunes as well as on the beach. Gassaway (1935, p. 4) reports black sand layers on the beach to be up to 2 feet in thickness with a gold content of less than commercial grade. The gold was reported to be extremely fine and difficult to amalgamate.The immediate source of the placer gold is thought to be the nearby bluffs of glacial gravels and tills.
Comment (Geology): Age = Quaternary
