Satelite View

The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

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
