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): IN SITU MINING PROPOSED, USING A FIVE-WELL PATTERN (4 INJECTION WELLS SURROUNDING A RECOVERY WELL); LEACH SOLUTIONS CONSIDERED INCLUDE AMMONIUM BICARBONATE, SODIUM BICARBONATE, AN ALKALINE-EARTH BICARBONATE, OR AN ACID SOLUTION; FIRST MINE UNIT ENCOMPASSES SEVERAL WELL FIELDS (TYPICALLY 10 ACRES EACH); WHEN PRODUCTION BEGINS ON THE THIRD MINE UNIT, RECLAMATION AND GROUNDWATER RESTORATION WILL BEGIN ON THE FIRST UNIT, PROGRESSING AS MINING PROGRESSES, BUT ALWAYS KEEPING ONE FIELD INACTIVE BETWEEN MINING AND RESTORATION; PLANT SITE IN N2 OF NW OF SECTION 25, T9N, R60W

Comment (Reserve-Resource): EXPECT TO PRODUCE 150,000 LBS YELLOW CAKE THE FIRST YEAR OF OPERATION, 250,000 LBS THE SECOND YEAR, AND 500,000 LBS/YEAR THEREAFTER UNTIL THE FIELD IS DEPLETED

Comment (Location): LATITUDE, LONGITUDE GIVEN ARE FOR CENTER, SW/4 OF SECTION 30, T 9 N, R59W, (FIRST PROPOSED MINE UNIT). SECTION FRACTIONS EXCLUDE TOWN OF KEOTA. ; INFO FROM LAND.ST :1976

Comment (Development): USING IN SITU MINING METHODS, THE MINE IS EXPECTED TO PRODUCE 150,000 LBS OF U308 FIRST YEAR, 250,000 LBS THE SECOND YEAR AND 500,000 LBS/YEAR OVER A 10 TO 20 YEAR LIFE. A REPEATING FIVE. WELL PATTERN IS PROPOSED WITH A DILUTE AQUEOUS CARBONIC ACID (WATER PLUS CARBON DIOXIDE, PH 6-7) PLUS OXIDANT (OXYGEN GAS INJECTED DOWN HOLE) LEACH. SOLUTION RECOVERY WILL BE AT A PH JUST SLIGHTLY OVER 7.

Comment (Deposit): THE ROLL FRONT DEPOSITS ARE FORMED AS COATINGS ON SAND GRAINS; THE DEPOSITS ARE SINUOUS AND ELONGATE WITH NARROW LATERAL WDITH
