L-Bar Deposits

The L-Bar Deposits is a uranium mine located in Cibola county, New Mexico at an elevation of 6,276 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: Private
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.

Comment (Commodity): ANALYTICAL DATA FROM JACOBSEN, 1980 P. 286

Comment (Location): GEODETIC AND UTM LOCATIONS ARE FOR SHAFT NEAR THE NORTHWEST END OF THE LARGEST OF THE DEPOSITS. SECTION LINES PROJECTED.

Comment (Deposit): DEPOSITS OCCUR IN ELONGATED TABULAR MASSES UP TO SEVERAL HUNDRED FEET WIDE, 1000 FT. LONG AND ABOUT 10 FT. TO 12 FT. THICK. DEPOSITS ARE CONCORDANT AND TREND SOUTHEAST.

Comment (Workings): MINERALIZATION OCCURS AT DEPTHS OF 200 FT. TO 700 FT. OPERATIONS IN 1980 WERE UNDERGROUND BUT OPEN PIT METHODS ARE POSSIBLE BECAUSE DEPTH TO MINERALIZATION VARIATIONS ARE CAUSED BY LOCAL TOPOGRAPHY.

Comment (Geology): ORE OCCURS IN THE BRUSHY BASIN MEMBER (JACKPILE SANDSTONE) OF THE MORRISON FM.
