Comments on the geologic information

  • STATEN (1976) AS CITED IN HENRY AND OTHERS (1979) NOTED CHLORITE SCHIST OFTEN FORMS AN ENVELOPE 0-1 M THICKNESS AROUND THE SULFIDE ZONES AND IS INTERLEAVED WITH QUARTZ-MUSCOVITE SCHIST. THIS IS ONLY MINE IN DISTRICT WHERE PYRITE IS MORE THAN A RARE CONSTITUENT OF THE ORE, AT THE BETTY BAKER MINE, PYRITE CONSTITUTES AS MUCH AS 25% OF THE ORE.

Comments on the workings information

  • DRIFTS WERE DUG AT THE 40 FT AND 80 FT LEVELS. KLINE AND BALLARD (1949) REPORT EXTENSIVE SURFACE WORKINGS FOR 5600 FT ALONG THE STRIKE OF THE ORE BODY. IN NOVEMBER, 1986, THE SURFACE WORKINGS CONSISTED OF A SERIES OF TRENCHES EXTENDING ROUGHLY 5000 FT TO THE SW FROM AN OPEN PIT. THIS PIT WAS APPARENTLY EXCAVATED IN THE MID 70'S FOR SOME PROSPECTING WORK--EXCELLENT EXPOSURES OF FOOTWALL ROCKS AND SOME ORE ZONE MATERIAL. NE OF THE PIT IS A BROAD ZONE OF SURFACE WORKINGS, INCLUDING PORTALS, SHAFTS, TRENCHES AND SPOIL PILES.

Comments on development

  • MINE OPENED IN 1854 BY MEIGS COUNTY, TENNESSEE, AND VIRGINIA MINING CO. WHO MINED SUPERGENE COPPER BELOW GOSSAN. THE MINE WAS CLOSED DURING THE CIVIL WAR AND NOT REOPENED UNTIL SOMETIME AFTER 1880. PRIOR TO ITS CLOSING IN 1900, THE MINE WAS OPERATED BY A CAPT. MCKEE WHO SHIPPED ORE TO THE SOUTHERN CHEMICAL CO. AT WINSTON-SALEM, N.C. FOR ACID MAKING PURPOSES. IN 1905, VIRGINIA IRON, COAL AND COKE CO. DEVELOPED MINE BY MEANS OF A SHAFT AND DRIFTS AT TWO LEVELS. IN 1928, 24 HOLES TOTALING 2808 M WERE DRILLED BY VIRGINIA IRON, COAL AND COKE CO. IN 1947, THE U.S. BUREAU OF MINES DRILLED SEVEN CORE HOLES TOTALING 1163 M.
