Red Cloud Mine

The Red Cloud Mine is a fluorine-fluorite mine located in Lincoln county, New Mexico at an elevation of 7,598 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.

Land Status

Land ownership: National Forest
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments

Comment (Commodity): BASTNASITE COULD BE A POTENTIAL ORE FOR CERIUM.

Comment (Location): IN THE CIBOLA NATIONAL FOREST ; INFO FROM LAND.ST :(1954)

Comment (Development): THE PROSPECT IS MADE UP OF ONE PATENTED CLAIM, THE RED CLOUD; AND ONE UNPATENTED CLAIM, THE CONQUERER NO. 9.

Comment (Deposit): MINERALIZATION OCCURS IN A BRECCIATED AND ALTERED SANDSTONE BODY THAT EXTENDS ACROSS THE COMMON BOUNDARY OF THE RED CLOUD AND CONQUERER NO. 9 CLAIMS. AN IRREGULAR FLUORSPAR BODY 65 FT BY 50 FT DEEP EXTENDS ABOUT 170 FT EAST-WEST. FLUORITE IS ASSOCIATED WITH QUARTZ, BARITE, CALCITE, SOME PYRITE, LIMONITE, BARYTOCELESTITE, AND THE RARE-EARTH MINERAL BASTNASITE. THE AVERAGE BASTINASITE CONTENT IS ESTIMATED TO BE ABOUT 5% BY VOLUME AND ITS AREA OF MINERALIZATION EXTENDS BEYOND THE AREA OF FLUORITIZATION. THE FLUORITE ORE IS IN AN AGGREGATE OF FRAGMENTS OF DENSE FINE-GRAINED PURPLE FLUORSPAR AND ROCK IN A SOFT FE-STAINED MATRIX OF LOOSELY CEMENTED TINY FLUORITE CRYSTALS, GRANULATED BARITE, AND CLAY. THE MINERALIZED BRECCIATED ZONE LIES JUST WEST OF THE INTERSECTION OF A NNW TRENDING FAULT AND AN ENE TRENDING FAULT. THE UPPER PORTION OF THE ORE BODY HAS BEEN ERODED AWAY.

Comment (Workings): THE ORE BODY IS DEVELOPED BY AN INCLINED SHAFT WITH LEVELS AT 35 AND 100 FT AND BY AN ADIT LEVEL AT THE ELEVATION OF THE SHAFT COLLAR.
