The West Anton Larsen Bay is a gold and silver 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): Age = Tertiary
Comment (Workings): Workings / Exploration = The prospect was developed by a 10-foot adit in 1934.
Comment (Geology): Geologic Description = This site represents the southern extension of the Kizhuyak lode as described by Capps (1937). Beach cliffs at this prospect show extensive mineralization in granodiorite near a contact with Cretaceous metasedimentary rocks. The deposit consists of a zone of many quartz veins up to 4 inches in thickness which are heavily mineralized in places with arsenopyrite and pyrite. The full width of the mineralized zone could not be determined. Several hundred feet on strike to the south similar mineralization is exposed in an open cut. The prospect was developed in 1934 by a 10-foot adit driven southward from the beach.
Comment (Reference): Primary Reference = Capps, 1937
Comment (Deposit): Model Name = Chugach-type low-sulfide gold-quartz vein (Bliss, 1992; model 36a.1).
Comment (Deposit): Other Comments = Site is located on land conveyed to the Koniag Corporation.
