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 (Production): IN 1941, 300 TO 400 TONS WERE MINED AND MILLED FOR MOS2 BUT DID NOT MEET SPECIFICATIONS.

Comment (Workings): MINE IS DEVELOPED BY 300 FT VERTICAL SHAFT AND 885 FEET OF DRIFTS AND CROSSCUTS ON 3 LEVELS. ADIT IS A DRIFT 110 FT LONG AND 60 FT CROSSCUT.

Comment (Deposit): THE MAIN VEIN CHARACTERIZED IN PLACES BY A SINGLE GOUGE BAND A FEW INCHES THICK AND ELSEWHERE BY A ZONE OF BRECCIATION 4 TO 6 FT WIDE. ORE BODIES LENTICULAR IN PLAN AND ARE AS MUCH AS 130 FT LONG AND 4 FT WIDE.
