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 (Deposit): THE ORE BODIES RANGED FROM 3 TO 6 FEET IN WIDTH AND FROM A FEW FEET TO 20 FEET IN LENGTH. DEPOSIT IS A CONTINUATION OF THE MAGNET DEPOSIT

Comment (Workings): WORKINGS CONSIST OF ADIT AND INCLINED SHAFT, AND A FEW SHALLOW CUTS

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 FEET FROM THE SURFACE

Comment (Commodity): MN ORE NOT AMENABLE TO CONCENTRATION BY FLOTATION FROCESS DUE TO IRON OXIDE CONTENT

Comment (Development): KENO, A FRACTIONAL CLAIM, ORIGINALLY BELONGED TO THE SUPERIOR AND GLOBE MINING CO., ALONG WITH THE COPPER TRUST AND MAGNET GROUPS. IT ADJOINS THE NORTHEAST END OF THE MAGNET GROUP. THE KENO, ALONG WITH THE COPPER TRUST AND MAGNET, WAS SOLD IN THE 1920'S OR 1930'S TO F.A. BENNET AND THEN IN 1953 TO F.A.SITTON. CLAIM WAS FIRST MINED IN 1940'S BUT DID NOT SHIP UNTIL 1953

Comment (Deposit): Discovery Year: 1880'S
