Lucky Day Group Uranium Prospect

The Lucky Day Group Uranium Prospect is a uranium mine located in Washoe county, Nevada at an elevation of 4,600 feet.

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 (Geology): ASH FLOW AND ASH FALL TUFFS ARE PRESERVED IN DOWN-FAULTED AREAS WHICH HAVE HAD FURTHER VOLCANISM; ANDESITE PARTIALLY BURIES RHYOLITE TO THE NORTHWEST. AREA HAS APPEARANCE OF CALDERA MINUS CENTRAL UPLIFT. FINE, CRYSTALLINE, RED, SILICIFIED RHYOLITE, ARGILLIZED AND BROKEN BY FAULTING. UNALTERED RHYOLITE SHOWS SOME GREEN FERROUS OXIDE COLORATION. A WEDGE OF AULD LANG SYNE SEDIMENTS ABUTS AGAINST THE FAULT ON THE SOUTH AND IS SURROUNDED BY INTRUSIVE RHYOLITE. DEPOSIT IS ASSOCIATED WITH AN INTRUSIVE RHYOLITE DIKE IN OR NEAR THE EDGE OF THE CALDERA. URANIUM OCCURS IN FORM OF SECONDARY MINERALS IN NW TRENDING SHEETED ZONES IN RHYOLITE ASH FLOW TUFF OF HARTFORD HILL RHOLITE AND TUFFACEOUS SANDSTONE AND CONGLOMERATE OF THE CHLOROPAGUS FORMATION.

Comment (Deposit): THIS RECORD HAS BEEN MERGED WITH RECORD M242695, WHICH HAS BEEN DELETED.

Comment (Workings): 40-FOOT DOZER CUT ON FACE OF CLIFF ON RED MOUNTAIN AND 4-F00T ADIT 250 FEET SOUTH OF CUT; PROSPECT PITS; SEALED ADIT. A SHORT ADIT TO THE EAST IS ABOVE MAIN ORE AREA AND ABOUT 200-300 FEET HIGHER. UPPER ADIT HAD ONLY 400-500 CPS (10XBG).

Comment (Deposit): YELLOW URANIUM MINERALS IN BRECCIA FRAGMENTS, BUT BRECCIA ZONE IS NOT FULLY MINERALIZED. ZONE MAY BE BETTER AT DEPTH. URANIUM MINERALIZATION IS FAULT-CONTROLLED. CURRENT ORE EXPOSED IS JUST BELOW OLD LAKE LAHONTAN LEVEL, WHICH MAY HAVE PRODUCED SOME CONCENTRATION JUST BELOW WATER LEVEL.

Comment (Location): AT BASE OF PROMINENT RED MOUNTAIN ON WEST FLANK OF NIGHTINGALE MOUNTAINS. SITE IS APPROXIMATELY 1 MILE SOUTH OF PERSHING/WASHOE COUNTY LINE. UTM IS FROM SAMPE SITE. ; INFO FROM LAND.ST :(1972)

Comment (Development): AREA PROSPECTED IN EARLY 1950S, BY DOZER TRENCHING, ONE ADIT 200 FEET LONG. RECENT (1978) DOZER WORK AND SHALLOW 4-FOOT HOLE (ADIT) INDICATE CONTINUED INTEREST IN THE PROSPECT.
