  • Quartz Veins

Comments on the geologic information

  • THE SHAFT WAS OPENED IN QUARTZ VEINS IN SERICITE PHYLLITE. MOST OF THE DUMP MATERIAL IS VUGGY, IRON-STAINED VEIN QUARTZ CONTAINING SMALL AMOUNTS OF DECOMPOSED PYRITE. A SMALL AMOUNT OF GALENA IS DISSEMINATED THROUGH THE QUARTZ.

Economic information about the deposit and operations

Development status Past Producer
Commodity type Both
Significant No
Discovery year 1882
Year of first production 1882

Mining district

District name Carolina Slate Belt

Comments on the production information

  • PRODUCTION WAS PROBABLY FROM A SMALL AMOUNT OF HIGH-GRADE ORE; BOTH GOLD AND SILVER PRODUCED

Comments on the reserve resource information

  • PROBABLY LOW-GRADE GOLD-BEARING QUARTZ IN UNMINED VEINS STILL REMAINS; LOW-GRADE SULFIDE ZONE OF UNKNOWN EXTENT PRESENT.

Comments on the workings information

  • THE MAIN SHAFT IS 15 FT. BY 15 FT. AND WAS CHOKED TO WITHIN 30 FT. OF THE SURFACE IN 1969. NUMEROUS SMALL PROSPECT PITS ARE ON THE EAST SIDE OF THE HILL. THE MINE EXPLORED THREE QUARTZ VEINS. THE SHAFT WAS SUNK TO 80 FT AND SOME SILVER AS WELL AS GOLD WAS IN COUNTERED. ONLY A SMALL AMOUNT OF ORE WAS PRODUCED FROM THIS MINE.

Comments on development

  • DRILLING BY THE U. S. B. M. REVEALED A MINERALIZED ZONE OF SILICIFIED SERICITE SCHIST CONTAINING A SPRINKLE OF SULFIDES. THE DRILLING WAS PART OF THE BUREAU'S STRATEGIC MINERALS SURVEY.
