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 (Development): MAGNET CLAIM ORIGINALLY BELONGED TO THE SUPERIOR AND GLOBE MINING CO. ALONG WITH THE COPPER TRUST AND KENO. IT WAS EXPLORED FOR COPPER AND SILVER WITHOUT SUCCESS. MAGNET, ALONG WITH KENO AND COPPER TRUST SOLD TO BENNET AND THEN TO SITTON.
Comment (Deposit): GENERALLY THE PRODUCTIVE BODIES APPEARED TO BE LENTICULAR, RANGING FROM 3 TO 12 FEET IN WIDTH AND FROM 60 TO MORE THAN 200 FEET IN LENGTH
Comment (Workings): THE PRINCIPAL WORKINGS CONSISTED OF OPENCUTS DUG ALONG THE OUTCROP ALMOST THE ENTIRE LENGTH OF THE CLAIM AND FOUR SHAFTS
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 (Commodity): MN ORE NOT AMENABLE TO CONCENTRATION BY FLOTATION PROCESS DUE TO IRON OXIDE CONTENT
Comment (Deposit): Discovery Year: 1880'S
