Satelite View

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

Comments
Comment (Commodity): MN ORE NOT AMENABLE TO CONCENTRATION BY FLOTATION PROCESS DUE TO IRON OXIDE CONTENT
Comment (Development): COPPER TRUST GROUP OF CLAIMS ORIGINALLY OWNED, ALONG WITH THE MAGNET AND KENO, BY THE SUPERIOR AND GLOBE COPPER MINING CO. WHO UNSUCCESSFULLY EXPLORED FOR COPPER UP TO 1910. IT WAS SOLD IN 1920'S OR 1930'S ALONG WITH THE MAGNET AND KENO TO F.A.BENNET, THEN RESOLD IN 1953 TO F.A. SITTON.
Comment (Workings): SUPERIOR AND GLOBE PUT DOWN A 900 FT SHAFT WHILE EXPLORING FOR COPPER AND SILVER. THE MANGANESE ORE THAT WAS SHIPPED WAS SORTED FROM THE MATERIAL BROKEN IN AN OPEN CUT, 30X8X8 FT. SOME EXPLORATORY STRIPPING OF TALUS OVERBURDEN HAD BEEN DONE SOUTHWEST OF THE OPEN CUT
Comment (Geology): THE BEST ORE WAS FORMED BY RESIDUAL CONCENTRATION AND DOWNWARD ENRICHMENT OF MANGANESE OXIDES AND DID NOT EXTEND BELOW A DEPTH OF ABOUT 20 FT FROM THE SURFACE
Comment (Deposit): Discovery Year: 1880'S
