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 (Location): ON ALPHA MOUNTAIN, NW SIDE ; INFO FROM LAND.ST :(1972)

Comment (Development): VERY LITTLE PROSPECTING APPEARS TO HAVE BEEN DONE HERE CONSIDERING THE HISTORY OF MINERALIZATION (1984) LAND OWNED BY SOUTHERN PACIFIC RAILROAD

Comment (Deposit): 4 PARALLEL QUARTZ VEINS UP TO 14 INCHES WIDE WITH GOUGE OR SOLID MINERAL OF ARSENOPYRITE ON THE FOOTWALL. OLD WORKINGS HAVE BEEN PARTIALLY BULLDOZED.

Comment (Workings): A NUMBER OF OPEN CUTS, SHALLOW OLD ADITS AND PROSPECTS WITH MORE RECENT BULLDOZING
