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 (Production): UNRECORDED PRODUCTION PRIOR TO 1901

Comment (Reserve-Resource): REED (1951) STATES THAT ABOUT 40% OF ORE DEVELOPED BY UNDERGROUND WORKINGS REMAINS UNMINED

Comment (Workings): DEVELOPED BY A TWO-COMPARTMENT INCLINED SHAFT 168 M DEEP WITH FIVE LEVELS. IN 1949 WORKINGS WERE FLOODED TO A POINT 15 M BELOW THE SHAFT COLLAR.

Comment (Deposit): VEIN PARALLEL TO KEATING VEIN ABOUT 700 M EAST

Comment (Reserve-Resource): ASSUMING MINERALIZED AREA 3 FT X 700 FT X 1600 FT GIVES 280,000 ST OF WHICH 190,000 ST HAS BEEN MINED AND AN ADDITIONAL 125,000 ST HAS BEEN GIVEN AS RESERVES. THESE TOTAL 315,000 ST; THUS IT WOULD APPEAR THAT POTENTIAL RESOURCES WOULD HAVE TO BE DEVELOPED AT GREATER DEPTH OR AN EXTENSION OF THE VEIN WOULD HAVE TO BE FOUND.

Comment (Deposit): Discovery Year: 1860-1870
