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.

Comment (Location): ACCESSIBLE BY GOOD ROAD NORTH OF NIGHTINGALE MINE. LOCATION GIVEN HERE IS FROM ORIGINAL MRDS #M242702. LOCATION OF ORIGINAL M060211 IS: 40-03-41N/ 119-12-57W (UTMS: 44355741N; 3110084E). ORIGINAL M060211 CONTAINED NO REFERENCES TO VERIFY LOCATION. ; INFO FROM LAND.ST :(1972)
Comment (Commodity): TOO SMALL IN SIZE TO BE ECONOMIC
Comment (Deposit): Discovery Year: 1950'S
Comment (Deposit): A SMALL ROOF PENDANT OF QUARTZITE NEAR CONTACT WITH GRANODIORITE. THE GRANODIORITE IS STRONGLY WEATHERED INTO GRUSS. THE QUARTZITE IS HIGHLY FRACTURED AND HAS URANOPHANE COATINGS ON FRACTURES WITHIN THE SMALL AREA. URANOPHANE AND URANIFEROUS HYALINE OPAL ARE ASSOCIATED WITH INTRICATE AND COMPLEX LIMONITE-FILLED EASTERLY-TRENDING FRACTURES IN A QUARTZITE. HIGH RADIOACTIVITY IS PRESENT ALONG A 2-3 FT ZONE. A PEGMATITE DIKE CROPS OUT A FEW FEET AWAY. HIGHEST GRADE IS IN A 1-1.5 FT ZONE. FRACTURES IN QUARTZITE SHOW HIGHEST COUNT OF RADIOACTIVITY, ESPECIALLY IN A 6-INCH ZONE ON UPPER SIDE OF PENDANT AND AT BASE IN GRANODIORITE. REDUCTANT WAS PROBABLY PYRITE OR MARCASITE.
Comment (Workings): A 6-FT DEEP PIT AND DOZER CUTS
