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 (Geology): Geologic Description = The country rock in the area of this occurrence is the Lower Mississippian to Middle Devonian Totatlanika Schist. The deposit is in schist and consists of lenses of massive chalcopyrite, galena, pyrite, and sphalerite, accompanied by chlorite, quartz, and sericite (www.grayd.com, 1999).
Comment (Exploration): Status = Active?
Comment (Reference): Primary Reference = Cox and others, 1989
Comment (Workings): Workings / Exploration = Surface workings only.
Comment (Geology): Age = the deposit is interpretted to have formed synchronously with the deposition of the mid-Paleozoic protoliths of the Totatlanika Schist.
Comment (Deposit): Model Name = Kuroko massive sulfide (Cox and Singer, 1986; model 28a)
