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 = Jasper, 1965

Comment (Workings): Workings / Exploration = Unknown

Comment (Exploration): Status = Inactive

Comment (Geology): Geologic Description = Disseminated chalcopyrite and magnetite in a small, mafic segregation in a Jurassic age quartz diorite (Jasper, 1965). Copper deposits probably similar to those reported on Sheep Mountain - ARDF number AN080 (Berg and Cobb, 1967).

Comment (Deposit): Other Comments = Reported to be similar to deposits at Sheep Mountain - ARDF number AN080.

Comment (Deposit): Model Name = Porphyry Cu ? (Cox and Singer, 1986; model 17 ?)

Comment (Geology): Age = Jurassic or younger; mineralization hosted by mafic segregations in a Jurassic quartz diorite.

Comment (Geology): Age = Host rock is Jurassic.
