Comments on the production information

  • SAFFORD STATES THAT PRODUCTION FROM 1850 TO THE TIME OF HIS WRITING (ABOUT 1860) WAS 2 OR 3 TONS. CONFEDERATE PRODUCTION NOT KNOWN, BUT GALENA IS SAID TO HAVE OCCURRED IN POCKETS RANGING FROM 0.5 TO 1 TON (SWINGLE, 1959). SECRIST (1924) REPORTS THAT ONE TON WAS SHIPPED IN 1915. PRODUCTION FOR 1919 UNKNOWN.

Comments on the workings information

  • SECRIST (1924) DESCRIBES THE DEVELOPMENT AS CONSISTING OF A 50-FOOT LONG OPEN CUT, A 90-FOOT DEEP SHAFT, AND A SHORT TUNNEL. NUMEROUS SHALLOW PITS WERE OBSERVED IN THE SURROUNDING FIELDS BY SECRIST.

Comments on development

  • THE CONFEDERATE GOVERNMENT WORKED THE MINE DURING 1861-1863, EMPLOYING 100 MEN. THE CHATATA LEAD AND ZINC COMPANY WORKED THE MINE DURING 1915 AND 1919. ; ECON.COM: TONNAGE IS NOT BELIEVED TO BE LARGE (SWINGLE, 1959).

Deposit MR. HAMBRIGHT IS QUOTED BY SAFFORD (1869) "THE GALENA EXPOSED WAS A CONTINUOUS LAYER, RANGING ONE TO FOUR INCHES IN THICKNESS, AND ASSOCIATED WITH MORE OR LESS BLENDE, AND OTHER ORES OF ZINC. WHERE THE LAYER OF GALENA WAS THIN, THE ENCLOSING ROCKS HELD MORE OR LESS OF THE ORE IN GRAINS". MASSES OF GALENA WEIGHING FROM 200 TO 300 POUNDS WERE FOUND IN THE NEIGHBORHOOD OF THE VEIN. MINERALS OBSERVED ON THE WELL-COMBED AND DEPLETED DUMP WERE PYRITE, GALENA, BARITE, SPHALERITE, AND GANGUE CALCITE AND DOLOMITE. RELATIVE ABUNDANCE COULD NOT BE DETERMINED, BUT BARITE AND GALENA WERE THE MOST COMMON (SWINGLE, 1959). BARITE LOCALLY ENCLOSES IRREGULARLY-SHAPED CRYSTALS OF GALENA AND FORMS VEINLETS TRAVERSING THE GALENA. PYRITE AND SPHALERITE OCCUR AS IRREGULAR GRAINS AND SMALL MASSES ASSOCIATED WITH GANGUE CARBONATE. KILLEBREW AND SAFFORD (1874) IN SWINGLE (1959), STATE THAT THE GALENA OCCURRED IN POCKETS, EACH POCKET YIELDING FROM ONE-HALF TO ONE TON. ; INFO.SRC : 1 PUB LIT
