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

Comments
Comment (Location): UTM PRECISION 500M
Comment (Deposit): FRACTURED PERMEABLE ZONES INTERSECTING FAVORABLE DEPOSITIONAL HORIZONS CAPPED BY SHALE.
Comment (Geology): THE ORE BODIES ARE LOCALLIZED IN STEEPLY DIPPING BEDS NEAR THE TOP OF THE FORMATION SUGGESTING THE ORE FLUIDS TRAVELED UP THE FRACTURED ROCK TO BE CAPPED BY THE DUNDERBERG SHALE. THE EASTWARD CONTINUATION OF THE DIAMOND TUNNEL THRUST IS PRESENT AT SHALLOW DEPTH AND MAY ALSO HAVE ACTED AS A CHANNEL WAY FOR THE ORE FLUIDS.
Comment (Deposit): 171 TONS OF ORE VALUED AT $6,521 WERE PRODUCED DURING 1922-23. THE PROPERTY IS LOCATED ALONG THE DUNDERBERG-WINDFALL BELT ONE OF FIVE MINERALIZED BLOCKS IN THE DISTRICT ; INFO.SRC : 1 PUB LIT
