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 report
Comment (Workings): Workings / Exploration = The vein can be traced in outcrop or by float for a distance of about 600 feet.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Mid-Cretaceous or younger; vein crosscuts rocks regionally metamorphosed in the mid-Cretaceous.
Comment (Geology): Geologic Description = This prospect is on a simple quartz vein, as much as 3 feet thick and 600 feet long, that strikes northwest and dips steeply. It cuts across the schistosity of the host micaceous calc-schist. The vein contains as much as several percent of stibnite and galena. It is within a major geochemical soil anomaly characterized by gold, arsenic, and lead, that extends from the Rodine prospect (NM165) to Bangor Creek north of the Twin Mountain prospect (NM186).
Comment (Deposit): Model Name = Simple Sb deposit (Cox and Singer, 1986; model 27d).
