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 (Workings): Workings / Exploration = Discovered and explored in 1963 by 30 ft (9 km) long timbered and lagged open cut; 3.5-ft (1 m)-deep winze started on ore shoot.

Comment (Reserve-Resource): Reserves = Jasper (1963) estimated that the 5-6 tons of sorted and stockpiled ore would run 10-15% Hg.

Comment (Reference): Primary Reference = Jasper, 1963

Comment (Deposit): Model Name = Epithermal vein, mercury

Comment (Geology): Geologic Description = Small lenses and pods of cinnabar occur in brecciated silicified shaly sandstone intruded by altered dike or sill.

Comment (Exploration): Status = Inactive
