The Cleopatra 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 (Reference): Primary Reference = Cox and others, 1989

Comment (Geology): Age = The disseminated sulfides are probably syngenetic with their Late Triassic host rocks.

Comment (Geology): Geologic Description = The country rocks in the area of the Cleopatra prospect include Upper Triassic, intensely deformed and metamorphosed, interbedded shale, argillite, sandstone, siltstone, and argillaceous limestone; and dikes, sills, and small plugs of altered diabase and gabbro (Wilson and others, 1998). These rocks in turn are intruded by Upper Cretaceous(?) and Lower Tertiary granite plutons. The deposit consists of stratabound disseminated chalcopyrite and pyrrhotite in the metasedimentary rocks.

Comment (Workings): Workings / Exploration = Rocks are stream-sediment sampling, ground EM and magnetic geophysical surveys were conducted in the mid-1970s (unpublished report for the New Alaska Syndicate, 1977).

Comment (Deposit): Model Name = Besshi massive sulfide (Cox and Singer, 1986; model 24b)

Comment (Exploration): Status = Inactive
