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 (Geology): THE BLACK MOUNTAINS ARE IN A TILTED FAULT BLOCK IN WHICH THE VOLCANIC ROCKS STRIKE NORTHWARD AND DIP EASTWARD. AT OATMAN, THE VOLCANIC ROCKS DIP ABOUT 12 DEGREES EAST BUT TO THE WEST THEY DIP MORE STEEPLY.
Comment (Deposit): THE BRUCITE DEPOSITS ARE LAYERS AS MUCH AS 30 FT THICK RESTING ON THE ALCYONE TRACHYTE, THE OLDEST UNIT OF THE MID-UPPER TERTIARY VOLCANIC ROCK SEQUENCE. THE DEPOSITS ARE GENERALLY OVERLAIN BY OATMAN ANDESITE BUT AT SEVERAL PLACES THE BRUCITE LAYERS APPEAR TO BE WITHIN THE ANDESITE. SOME LAYERS AS MUCH AS 4-5 FT THICK BUT MOSTLY THINLY LAMINATED MATERIAL OF ALTERNATING BANDS OF CONTRASTING SHADES OF GREEN, GRAY, YELLOW, AND WHITE. FRESH BRUCITE RANGES FROM SERPENTINE GREEN TO LIGHT GRAY TO ALMOST WHITE. THE BRUCITE IS CRYPTOCRYSTALLINE AND DENSE WITH SUBCONCHOIDAL FRACTURE.
Comment (Development): DIAMOND DRILLED IN THE 1940'S. ; ECON.COM: DEPOSITS ARE TOO SMALL AND TOO LOW GRADE TO BE MINED PROFITABLY.
