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 (Location): SECTION SUBDIVISIONS SE 1/4 NE 1/4 NW 1/4

Comment (Workings): WORKINGS CONSIST OF A TRENCH & DOZER CUTS

Comment (Geology): IN SOME PLACES THE INTRUSIVE IS MARKED BY A CHILLED GLASS BORDER. A 20 FT ZONE OF CALCAREOUS CLAY SURROUNDS THE INTRUSIVE.

Comment (Development): RECENT URANIUM EXPLOR. INDICATES A FAIR U3O8 CONTENT (UP TO 0.15-0.20%), BUT IT OCCURRS IN COMPLEX STRUCTURE WITH F IONS WHICH MAKES IT ECONOMICALLY MARGINAL FOR EXTRACTION

Comment (Deposit): SMALL FLUORSPAR VEINS LESS THAN ONE INCH IS FOUND IN THE CLAY ZONE.

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