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.

Comment (Production): 1200-1500 TONS

Comment (Deposit): LENSES AND IRREGULAR BODIES OF MANGANESE OXIDES ALONG FISSURE ZONES IN LIMESTONE. FISSURE ZONE STRIKES N10W, STEEPLY DIPPING, IN NACO LIMESTONE. HIGH GRADE ORE BODIES RANGE FROM 1 TO 3 FT IN WIDTH AND FROM 15 TO 70 FT IN LENGTH

Comment (Workings): ORE HAS BEEN TAKEN FROM SEVEN OR MORE SHALLOW OPEN CUTS THAT EXTEND SOME 400 FT ALONG STRIKE. THE DEEPEST WORKING WAS AN OPEN PIT 15 TO 20 FT IN DIAMETER AND ABOUT 25 FT DEEP
