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.

Comment (Deposit): DEPOSITS OCCUR IN SIX EASTWARD-TRENDING OREBODIES COMPOSED OF MANY SMALLER PARALLEL AND SUBPARALLEL PODS, ORE ROLLS AND MANTO-LIKE SHEETS. OREBODIES RANGE FROM 200 FT. TO 1800 FT. LONG, 75 FT. TO 900 FT. WIDE, AND 4 FT. TO 12 FT. THICK. THE LARGEST OREBODY AND THE THREE SMALLEST ONES ARE IN SEC. 18. PODS AND ORE ROLLS RANGE FROM 3 FT. TO 50 FT. LONG AND FROM 4 FT. TO 5 FT. THICK. SHEETS UP TO 12 FT. THICK OCCUR. THE WESTWATER CANYON SANDSTONE CONTAINS PODS AND SOME ORE ROLLS, THE POISON CANYON SANDSTONE CONTAINS PODS AND SOME SHEETS.

Comment (Workings): ACCESS CONSISTS OF A 1380 FT. VERTICAL SHAFT. EXTENT OF UNDERGROUND WORKINGS NOT REPORTED. OPERATION USES SAND SLURRY BACKFILL AND PUMPS ABOUT 1000 GPM MINE WATER.

Comment (Geology): ORE OCCURS IN THE WESTWATER CANYON AND BRUSHY BASIN (POISON CANYON SANDSTONE) MEMBERS OF THE MORRISON FM.

Comment (Commodity): ANALYTICAL DATA FROM FALKOWSKI, 1980 P. 235

Comment (Location): GEODETIC AND UTM LOCATIONS ARE FOR MAIN SHAFT. OREBODIES ARE IN THE SE QUARTER OF SEC. 7 AND THE NE QUARTER OF SEC. 18.

Comment (Development): ORE BODIES DISCOVERED AND DELINEATED BY DRILLING AND GEOPHYSICAL LOGGING. REPORTED TO BE A 750 TON PER DAY OPERATION.
