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 (Location): SECTION SUBDIVISIONS SW 1/4 SE 1/4

Comment (Deposit): THE ORE BODY AT THE SURFACE IS AN OVAL PIPE HAVING A LENGTH OF 27 FT & A MAX. WIDTH OF 20 FT. THE ORE IS PURPLE-DARK BLUE, SOME OF IT IS SOFT & FRIABLE & SOME OCCURRS AS A HARD BOXWORK.

Comment (Commodity): CHIEF IMPURITIES ARE MONTMORILLONITE, CREAM COLORED DOLOMITE & QUARTZ

Comment (Workings): WORKINGS CONSIST OF AN ADIT 205 FT. LONG DRIVEN TOWARD THE ORE BODY. FROM ITS END A RAISE WAS EXTENDED 100 FT TO THE SURFACE. A 50 FT TRENCH WAS CUT FROM THE TOP OF THE RAISE TO THE OPEN CUT. ANOTHER 50 FT RAISE WAS ALSO MADE OFF THE FIRST RAISE.
