Mine Info

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): INITIAL PROSPECTING TOOK PLACE IN THE EARLY 1880'S. BY 1886 A GOOD VEIN WAS DISCOVERED AND SHIPPING COMMENCED. IN 1887 20 TONS OF ORE WAS SHIPPED AND THE LOWER OR MAIN TUNNEL WAS STARTED. IN 1888 ADDITIONAL RICH ORE WAS FOUND. IN 1889 THE PROPERTY WAS WORKED BY LESSES. IN 1890 THE PROPERTY WAS INCORPORATED AT COUNCIL BLUFFS. BY 1900 THE MAIN VEIN HAD BEEN OPENED 300 FT ON ITS DIP AND YIELDED EXCELLENT ORE. ABOUT 1905, AFTER A PERIOD OF INACTIVITY, THE MAIN TUNNEL WAS EXTENDED SEVERAL HUNDRED FEET AND A RICH LEAD-SILVER ORE BODY WAS DISCOVERED

Comment (Deposit): ORE WAS LOCATED IN FISSURES STRIKING NORTHEAST. THIS FISSURE ZONE IS THE SOUTHWESTERN EXTREMITY OF THE CRESCENT FISSURE.

Comment (Workings): WORKINGS CONSIST OF INCLINES AND A SERIES OF TUNNELS. ONE INCLINE IS 150 FT DEEP AND THE OTHER ABOUT 300 FT. THE LOWER, OR MAIN TUNNEL, IS OVER 800 FT IN LENGTH. THE TUNNELS IN GENERAL EXTEND TOWARDS THE SOUTHEAST AND THE INCLINES DIP STEEPLY TO THE SOUTHEAST. APPROXIMATELY 1400 FT OF WORKINGS ARE KNOWN NUMEROUS PROSPECT PITS ALSO ARE PRESENT.

Comment (Location): INFO FROM LAND.ST :1983

Comment (Production): PRODUCTION WAS INTERMITTENT AND NO ACCURATE RECORDS ARE AVAILABLE. PROPERTY WAS SHIPPING ORE BY THE EARLY 1880'S. IN 1887 50,000 LBS OF HIGH-GRADE ORE WAS PRODUCED. SOME PRODUCTION IN 1894, AND 1900. REGULAR SHIPMENTS WERE MADE IN 1906. LAST YEAR OF PRODUCTION NOT ACCURATELY KNOWN.

Comment (Deposit): Discovery Year: LATE 1870'S

Comment (Geology): PROPERTY LIES JUST NORTH OF THE CLAYTON PEAK STOCK. SEDIMENTARY UNITS SHOW HIGH DEGREE OF CONTACT METAMORPHISM. CRESCENT FISSURE ZONE PASSES THROUGH PROPERTY AND HOSTS MINERALIZATION.
