Satelite View

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

Comments
Comment (Location): ELEVATION OF MAIN INCLINE SHAFT TAKEN FROM MAP FROM ROBERTSON REFERENCE ; INFO FROM LAND.ST :(1959)
Comment (Commodity): GOLD OCCURS IN THE OXIDIZED PARTS OF THE VEIN, POSSIBLY WITHIN THE ARSENOPYRITE STRUCTURE
Comment (Reserve-Resource): THE INTERSECTION OF THE EMMA DARLING AND THE BONANZA-HIDDEN HAND VEIN MIGHT BE INVESTIGATED
Comment (Development): ECON.COM: ORE IS COMPLEX; DIRECT SHIPPING ORE PENALIZED FOR ARSENIC
Comment (Deposit): THE VEIN IS VERY SINUOUS, BUT IN THIS PARTICULAR AREA (ROBERTSON) IS GENERALLY N TO NE-TRENDING. SIZE DATA IS FOR ORE SHOOT FROM WHICH ORE WAS SHIPPED BEFORE 1928.
Comment (Workings): LARGE BULLDOZER CUTS, ADITS, SHAFT
Comment (Geology): LOW ANGLE REVERSE FAULTS
