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 (Deposit): THE VEINS ARE 2 FT TO 20 FT WIDE. THEY ARE OPEN TEXTURED, SPONGY AND CONTAIN SOLUTION CAVITIES RANGING IN SIZE FROM SMALL VUGS TO ELONGATE CAVES.
Comment (Workings): IN 1942 THE DEWEY WAS REPORTED TO BE INACCESSIBLE AND THE WHITE SWAN WAS ONLY ACCESSIBLE TO THE 80 FT LEVEL AND THE 130 FT LEVEL. 5 PATENTED CLAIMS COVERING ABOUT 90 ACRES. SEE NEW MEXICO MINERAL PLAT SURVEY NUMBER 1439.
Comment (Geology): FOR GENERAL GEOLOGY SEE SIERRA CABALLOS DISTRICT.
Comment (Deposit): THE DEWEY AND WHITE SWAN MINES HAVE BEEN REPORTED TO CONTAIN AN ESTIMATED 26000 TONS OF MEASURABLE, INDICATED AND INFERRED ORE WITH AN AVERAGE GRADE OF 0.53 % VANADIUM PENTOXIDE AND AT THE 1944 PRICES THIS ORE COULD NOT BE ECONOMICALLY MINED. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
Comment (Location): NORTHEAST OF PALOMAS GAP ON THE EAST FLANK OF THE NORTHERN CABALLOS MOUNTAINS.
Comment (Reserve-Resource): V RESOURCES PROBABLY NIL.
Comment (Production): A SMALL PLANT WAS BUILT AT CUTTER, N. MEX., TO MAKE V CONCENTRATES BUT OPERATED ONLY A SHORT TIME (LASKY, S. G., AND WOOTTON, T. P., 1933, NEW MEXICO SCHOOL MINES BULL. 7). HESS (1913) REPORTS A FEW HUNDRED POUNDS V2O5 PRODUCED IN 1911.
