Mining district

District name Carolina Slate Belt

Comments on the workings information

  • IN 1968, A SMALL TRENCH STRIKING N 35 DEG W AND A 12 FT. X 12 FT. X 6 FT. PROSPECT PIT WERE ALL THAT REMAINED OF THE WORKINGS. SOME DUMP MATERIAL WAS PRESENT.

Comments on development

  • MINE WAS WORKED BEFORE AND AFTER THE CIVIL WAR. PROSPECTING WAS CARRIED OUT ON THE PROPERTY IN 1906. SOME PRODUCTION WAS REPORTED IN 1920, 1921 AND 1923, AND CONSIDERABLE PROSPECTING WAS CARRIED OUT AGAIN IN 1933. ; ECON.COM: GOLD WAS DIFFICULT TO RECOVER DUE TO ITS FINENESS. LIMONITE PSEUDOMORPHS ASSAYED HIGHER THAN DID THE ORE.
