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 = Smith, 1913 (B 525)
Comment (Workings): Workings / Exploration = A tunnel driven on a north-trending vein exposed quartz and a cross-cutting fracture zone in fractured country rock (Smith, 1913 [B 525, p. 207]).
Comment (Deposit): Model Name = Schist-hosted gold-quartz vein
Comment (Geology): Geologic Description = A tunnel was driven on a north-trending vein that exposed quartz and a cross-cutting fracture zone in fractured country rock (Smith, 1913 [B 525, p. 207]). There is no data on ore grade,although it is assumed that this was a gold prospect (Cobb, 1976 [OFR 76-662, p. 44]).
Comment (Exploration): Status = Inactive
