Satelite View

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

Comments
Comment (Deposit): MINE LOCATED ON A FISSURE DEPOSIT PARALLEL TO AND NEARLY CONTINUOUS WITH THE CITY ROCKS FISSURE. EARLY MINING APPARENTLY MINED OUT THE FISSURE DEPOSIT. FISSURE IS EXTENSION OF BUTTE MINE
Comment (Workings): EARLY WORKINGS WERE CONNECTED WITH THE BUTTE MINE AND THEN LATER CONNECTED WITH THE CITY ROCKS TUNNEL AND TOPEKA TUNNEL
Comment (Location): INFO FROM LAND.ST :1983
Comment (Commodity): ONLY AG, PB, AND MINOR CU KNOWN TO BE PRODUCED
Comment (Production): ORE PRODUCED THROUGH 1880 WAS VALUED AT $10,000 AND ASSAYED AT 50 OZ/TON AG, AND 30% PB. LATER PRODUCTION TOTALED TWO RAILROAD CARS OF ORE. ONE CAR CONTAINED 9% CU AND 100 OZ/TON AG AND THE OTHER CAR ASSAYED 25% PB AND 35 OZ/TON AG.
Comment (Development): EARLY WORK DONE BETWEEN 1870 AND 1880 PRODUCED MOST OF THE ORE MINED FROM FISSURE. SECOND PHASE OF MINING FROM 1901 TO 1903 PRODUCED TWO RAILROAD CARS OF ORE
Comment (Geology): MINE LOCATED CLOSE TO ALTA STOCK, WITHIN 200 FT, AND HOSTING LIMESTONES SHOW BLEACHING AND CONTACT METAMORPHIC EFFECTS. PRODUCTION FROM FISSURES CUTTING THESE ROCKS.
