Satelite View

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

Comments
Comment (Reserve-Resource): THE INFERRED RESERVES WERE THOUGHT TO BE BETWEEN THE 18 AND 40 FT. LEVELS.
Comment (Development): THE FIRST DEVELOPMENT CONSISTED OF SINKING ON 18 FT. SHAFT AND OPEN-CUTTING THE ORE ALONG STRIKE, FROM THE SURFACE TO THE BOTTOM OF THE SHAFT. CROSSCUTS WERE DRIVEN, THE SHAFT WAS CONTINUALLY DEEPENED, AND THE ORE STOPED ALONG AND ACROSS THE STRIKE OF THE TACTITE ZONE.
Comment (Deposit): THE DIMENSIONS GIVEN REPRESENT THE SIZE OF THE ORIGINAL ORE BODY, AS EXPOSED ON THE SURFACE.
Comment (Workings): AN OPEN-PIT DEVELOPED BY SELECTIVE MINING OF THE TACTITE BODY ALONG THE LIMESTONE-QTZ. MONZONITE CONTACT. TWO SHORT ADITS, APPROX. 20 FT. AND 10 FT. LONG, WERE DRIVEN IN THE WEST SIDE OF THE PIT.
Comment (Location): SE SLOPE OF DUTCH MTN.
Comment (Production): REFERING TO FIELD 8, YEARS ARE 1942-1944 1954-1955; REFERING TO FIELD 9, YEARS ARE 1942-1944, 1954-1955
