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): SOUTHWARD-DIPPING LAVA FLOWS, INTERCALATED WITH THICK BEDS OF CONGLOMERATE, FORM A RUGGED TERRAIN. THIS CONGLOMERATE, WHICH CONSISTS MAINLY OF COARSE, SUBANGULAR PEBBLES OF GNEISS AND GRANITE, RATHER FIRMLY CEMENTED IN A SANDY TO CLAYEY MATRIX, FORMS THE BEDROCK OF THE PLACERS. THE GOLD BEARING GRAVELS OCCUR PRINCIPALLY AS ANCIENT BARS SEVERAL FEET ABOVE THE STREAM CHANNEL AND, TO A LESS EXTENT, IN THE PRESENT STREAM BED. THE GOLD OCCURS AS PARTICLES UP TO 0.15 INCH IN DIAMETER, MOSTLY CONCENTRATED AT OR NEAR BEDROCK. IT APPEARS TO HAVE BEEN DERIVED BY EROSIN OF THE CONGLOMERATE, IN WHICH IT WAS PROBABLY PRESENT AS LOW-GRADE PLACER MATERIAL DERIVED FROM GOLD BEARING QUARTZ VEINS ORIGINALLY CONTAINED IN THE GNEISS, SCHIST, AND GRANITE OF THE RANGE

Comment (Deposit): THE MAJOR PLACERS OCCUR IN BURRO CANYON. MINOR ONES ARE FOUND IN SMALLER CANYONS IN THE VICINITY OF A PROMINENT MOUNTAIN THAT IS VARIOUSLY KNOWN AS KLOTHO, CORONATION, OR MUGGINS PEAK, AND ALSO AT THE SOUTHERN BASE OF LONG MOUNTAIN ; INFO.SRC : 1 PUB LIT

Comment (Location): THE MUGGINS MOUNTAINS OCCUPY PARTS OF TS. 7 & 85, RS. 8,9, & 10W

Comment (Workings): NUMEROUS SURFACE WORKINGS
