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.

Comment (Geology): GEOL.DESC: ABNORMAL RADIOACTIVITY AMT. 10X BACKGROUND AT GREEN BOY CLAIM, IS ASSOCIATED WITH A BRECCIATED AND ALTERED SHEAR ZONE IN GRANODIORITE OF JURASSIC AGE. MAXIMUM RADIOACTIVITY ON FLORISTON CLAIMS IN A NARROW FAULT ZONE IN GRANITIZED SEDIMENTS. IN THE GREEN BOY, METAZENNERITE (?) OCCURS AS MINUTE CAVITY FILLINGS IN THE ROCK; MANGANESE OXIDES AND FLUORITE ARE ALSO PRESENT IN THE VEIN. RICHEST SAMPLE CONTAINED 0.5% U3O8. THE HIGHEST GRADE SAMPLE ON FLORISTAN CLAIMS CONTAINED 0.13% U3O8. OTHER MINERALS CONSISTED OF A BLUE SODIC AMPHIBOLE AND MINOR AMTS. OF PYRITE, CHALCOPYRITE, AND MALACHITE.
