Satelite View

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

Comment (Development): SHAFT SUNK IN 1880'S TO CUT VEIN AT 240 FT. WINZE SUNK TO 300 FT. LEVEL EXPOSING RICH ORE. SOME ORE WAS SHIPPED. MORE ORE DISCOVERED BY DRIFTING IN 1928, ON 300-FT. LEVEL, ANDE MORE ORE AT THE 360 FT. LEVEL PRODUCTION RECORDED ONLY FOR 1933.
Comment (Workings): SHAFT, WINZE, DRIFTS
Comment (Deposit): A SHAFT WAS SUNK IN THE 1980'S IN THE HANGING WALL AND ACCORDING TO NEWSPAPERS THE VEIN WAS CUT AT 240 FEET. A WINZE WAS SUNK ON IT TO THE 300 FOOT LEVEL EXPORING A WIDE VEIN WITH RICH ORE ON THE FONT WALL. SOME ORE WAS SHIPPED IN 1928 A STRONG WIDTH OF MINERALIZATION WAS DISCOVERED BY DRIFTS AT THE 300 FT LEVEL, THIS WAS SULFIDE ORE ASSAYED FROM $2 TO $200 PER TON WITH A RATIO OF MILLING GRADE MADE UP OF BARREN WHITE QUARTZ SURROUNDED BY BLACK QUARTZ CARRYING SILVER SULFIDES. IN 1933 THE COMPANY REPORTED A PRODUCTION OF 550 TONS OF A GROSS VALUE OF $3,924. ; INFO.SRC : 1 PUB LIT
