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.

Comment (Workings): Workings / Exploration = Adit driven N 65 E to crosscut vein, caved by early 1950,s (USGS B 989-D); tenor not known. Type of workings: underground

Comment (Reference): Primary Reference = Moffit, 1954, USGS B 989-D

Comment (Geology): Geologic Description = Stringers, 1/4 to 2 in thick, of quartz, calcite, pyrite, galena, and sphalerite in a zone 6 to 12 in wide cutting hornfelsed and dioritized volcanics of Pennsylvanian-Permian age. Deposit is in diorite gneiss which is cut by 8 ft thick trachyte dike that strikes N 55 W and dips 45 NE.
