The Unnamed (northeast of Ramsey Bay) is a copper and molybdenum 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 = This site was very briefly examined and sampled by an Aleut-Quintana-Duval joint venture in 1974 (Christie, 1974).

Comment (Exploration): Status = Inactive

Comment (Reference): Primary Reference = Christie, 1974

Comment (Geology): Age = Eocene or younger.

Comment (Geology): Geologic Description = The country rocks at this occurrence consist either of sedimentary units of the Miocene Bear Lake Formation or of volcanic and sedimentary units of the Oligocene to Eocene Stepovak Bay Formation (Wilson and others, 1995). Christie (1974) noted a small color anomaly at this location. He collected one silt sample that contained 48 ppm copper, 4 ppm molybdenum, 63 ppm zinc, and 1.6 ppm silver. MacKevett and Holloway (1977) describe the occurrence as an altered zone in Tertiary rocks.

Comment (Deposit): Other Comments = This site is on land selected by the Aleut Corporation.
