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): Discovery Year: ABOUT EARLY 1900'S
Comment (Production): PRODUCTION IS ESTIMATED TOTAL THROUGH 1954 TO HAVE BEEN ABOUT 23,038 TONS ORE AVERAGING 9.22% CU, 0.006 OZ/TON AU; 27 OZ/TON AG, WITH A SMELTER VALUE OF $468,193.00 (SMALL AMOUNT OF LEAD PRODUCED, AS WELL)
Comment (Development): EARLY PRODUCTION NOT RECORDED, BUT MUCH OXIDE ORE WAS OPEN-PIT MINED. PRODUCTION WAS GREATER THAN ALL OTHER COPPER BASIN MINES COMBINED (PRIOR TO DUVAL'S OPEN PIT). LITTLE ACTIVITY FROM 1930-1943
Comment (Deposit): SECONDARY ENRICHMENT, WHERE THE SWEET-MARIE FAULT RESTRICTED THE DOWNWARD MOVEMENT OF COPPER-BEARING SOLUTIONS TO FAVORABLE BEDS.
Comment (Workings): EXTENSIVE OLD UNDERGROUND WORKINGS MUCH OBLITERATED BY RECENT OPEN-PIT EXCAVATION
Comment (Deposit): PRODUCTION FROM THE SWEET MARIE MINE WAS PROBABLY. GREATER THAN THAT OF ALL OTHER COPPER BASIN AREA MINES (PRIOR TO DUVAL'S OPEN PITS). EARLY PRODUCTION WAS NOT ACCURATELY RECORDED, BUT MUCH OXIDIZED ORE WAS MINED FROM AN OPEN PIT. LITTLE ACTIVITY FROM 1930 TO 1943. WORKINGS ARE EXTENSIVE, BOTH SURFACE AND UNDERGROUND, ALTHOUGH MUCH OF THE OLD WORKINGS HAS BEEN OBLITERATED BY MORE RECENT OPEN-PIT EXCAVATION ; INFO.SRC : 1 PUB LIT
Comment (Commodity): MALACHITE, AZURITE, CHRYSOCOLLA(UPPER WORKINGS), CHALCOCITE BELOW.
