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 (Commodity): URANIUM ORE IS ECONOMIC. 1700 MET. TONS OF URANIUM ORE OF UNPUBLISHED GRADE WAS PRODUCED.

Comment (Production): PRODUCTIVE PERIOD IS 1935 - 1945, 1948 TO AT LEAST 1952 AND 1970 - ?

Comment (Workings): MAIN WORKINGS CONSIST OF A 26 M. SHAFT AN OPENCUT AND AN ADIT. INDIVIDUAL SHOOTS ARE 0.6 TO 1.8 M WIDE, 1.5 TO 3 M LONG, AND MORE THAN 7.6 M DEEP. SOUTHEASTERN ORE SHOOT WAS 2 M. WIDE, 3 M. LONG AND 17 M. DEEP

Comment (Location): A SMALLER MINE IS LOCATED ABOUT 0.8 KM SOUTH OF THE MAIN WORKINGS

Comment (Geology): DOLOMITE IS COMPOSED OF ANHEDRAL CRYSTALS AVERAGING 0.04 MM IN SIZE, LESS THAN ONE PERCENT QUARTZ IN ISOLATED ANGULAR GRAINS UP TO 0.08 MM IN SIZE. RHYOLITE HAS QUARTZ AND K-FELDSPAR GROUNDMASS WITH PHENOCRYSTS OF QUARTZ, SANIDINE, BIOTITE AND PLAGIOCLASE. SMALL AMOUNTS OF PYRITE AND ZIRCON OCCUR AS ACCESSORIES AND HEMATITE AND SERICITE AS ALTERATION PRODUCTS.
