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 (Workings): TWO LEVELS CONNECTED BY A 60 FT RAISE; THE UPPER LEVEL IS DRIVEN N70W FOR 70 FT; THE LOWER LEVEL IS DRIVEN N35E FOR 135 FT; ALSO SOME SHORT DRIFTS AND STOPS.
Comment (Geology): ORE MINERALS CONSTITUTE 25 % OF THE VEIN IN PLACES. NEAR THE RAISE CONNECTION FROM THE LOWER TUNNEL THE ORE IS FAULTED OFF BY A DIKE OF TERTIARY GRANITE PORPHYRY. ABOUT 70 FT FROM THE LOWER PORTAL A SECOND VEIN STRIKED N70W AND AVERAGES 14 IN IN WIDTH; THIS VEIN WAS NOT FOLLOWED EVEN THOUGH IT CONTAINS CONSIDERABLE MINERALIZATION.
Comment (Deposit): ADJOINS ANCHOR CLAIM (RECORD NO. M056637).
Comment (Commodity): TEST SHIPMENT PRIOR TO 1940
Comment (Development): ADITS, RAISE, DRIFTS, AND STOPS.
Comment (Deposit): FISSURE VEINS 1 TO 4 FT WIDE IN GRANITE.
