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 (Reference): Primary Reference = This record

Comment (Workings): Workings / Exploration = There has been only surface mapping and sampling.

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

Comment (Geology): Geologic Description = The country rocks in the area of this prospect are Upper Triassic, carbonaceous, calcareous shale, argillite, sandstone, and siltstone. This sequence is cut by dikes, sills, and plugs altered diabase and gabbro (Wilson and others, 1998). The deposit presumably consists of auriferous chalcopyrite and possibly other sulfides, disseminated in the sedimentary and (or) intrusive rocks.

Comment (Geology): Age = Late Triassic or younger.
