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 = This description

Comment (Geology): Geologic Description = This occurrence is a stratiform, black shale- and chert-hosted, synsedimentary, massive sulfide deposit in Mississippian to Permian strata (J. Britton, oral communication, 1998). Fifteen holes were drilled in the early 1980s. The drilling intercepted a complex, mineralized horizon grading less than 5% Zn and Pb over variable thicknesses, generally less than 20 feet. One mineralized intercept of more than 200 feet contained several intervals grading more than 10% combined lead and zinc. Another intercept graded more than 30% combined lead and zinc.

Comment (Workings): Workings / Exploration = Fifteen drill holes were completed in the early 1980s.

Comment (Geology): Age = Mississippian to Permian.

Comment (Deposit): Model Name = Sedimentary exhalative Zn-Pb (Cox and Singer, 1986; model 31a).

Comment (Exploration): Status = Inactive
