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 = No known activity.

Comment (Geology): Geologic Description = The occurrence is described as blocks of talus as much as 30 cm in diameter of pink- and cream-colored silicates with manganese values as much as 22.23 percent (Fechner and others, 1993). Manganese oxide-stained chert with fine- to coarse-grained chalcopyrite was found nearby. The mineralized chert gave values of as much as 16.36 percent Mn. The manganese-mineralized rubble crops do not extend more than 30 m in any direction. The area is mapped by Brosgi and Reiser (1964) as within the chert unit of a Devonian(?) sequence of volcanic rocks and chert.

Comment (Deposit): Model Name = Volcanogenic Mn(?) (Cox and Singer, 1986; model 24c)

Comment (Reference): Primary Reference = Fechner and others, 1993
