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 (Location): 0.7 MILE BEYOND SADDLE ON ROAD WHERE FOUR JACKS SAMPLES WERE COLLECTED. . INFO FROM LAND.ST :(1972)

Comment (Deposit): URANIUM AND POSSIBLY TUNGSTEN ARE PRESENT IN SKARN ZONE IN AULD LANG SYNE SEDIMENTS; TOO SMALL TO BE ECONOMIC. QUARTZITE BED IN SLATE WITH ADJACENT THIN (4-6 INCH) PEGMATITIE SILL, BLACK TO BUFF COLORED, STRONGLY IMPREGNATED WITH YELLOW SECONDARY URANIUM MINERALS. THE THIN QUARTZITE APPEARS TO CONTAIN THE HIGHEST URANIUM CONCENTRATION, THEN THE PEGMATITE. THE HORNFELS NEAR THE QUARTZITE CONTAINS ONLY MINOR QUANTITIES. AUTUNITE IS PRESENT ALONG FRACTURES AND BEDDING PLANES IN SCHISTS, PHYLLITES, AND SHALES, IN THE ROOF PENDANT

Comment (Geology): NUMEROUS DIKES OF PEGMATITE AND GRANODIORITE INTRUDED INTO METASOMATIZED SEDIMENTS OF AULD LANG SYNE GROUP PRESERVED AS ROOF PENDANTS IN NIGHTINGALE BATHOLITH.

Comment (Workings): OVER 2000 FT OF DOZER CUTS AND BENCHING
