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): 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
