Comments on the geologic information

  • ACCORDING TO ESPENSHADE (1942), "THE ORES ARE MASSIVE SULFIDES, COMPOSED PRINCIPALLY OF PYRRHOTITE ACCOMPANIED BY LESSER AMOUNTS OF CHALCOPYRITE. SECONDARY CHALCOCITE ORES HAVE BEEN FOUND IN PLACES BENEATH THE GOSSAN." ROSS (1935) STATES THAT BOTH THE SCHIST AND PEGMATITE ARE MINERALIZED, WITH SULFIDES REPLACING THE EARLIER FERROMAGNESIAN VEIN MINERALS AND THE ENCLOSING SCHISTS AND PEGMATITE. HE ALSO NOTES THAT VEINLETS OF SULFIDES TRANSECT QUARTZ, AMPHIBOLES, AND MICAS. EUHEDRAL PYRITE CRYSTALS LINE ABUNDANT SMALL, OPEN CAVITIES. THE CHALCOPYRITE IS ASSOCIATED WITH PYRRHOTITE; HOWEVER, SOME PYRRHOTITE IS FREE FROM CHALCOPYRITE. THE MASSIVE SULFIDES OCCUR NEAR THE CONTACT OF THE HORNBLENDE GNEISS AND A MICA-GARNET SCHIST AND GNEISS.

Comments on the workings information

  • THE PROPERTY HAS BEEN EXPLORED BY A SHAFT ON THE NW SIDE OF THE CREEK, THREE ADITS RANGING FROM 25 TO 40 FT LONG, AND THREE SHALLOW OPEN CUTS. ESPENSHADE (1942) STATES THAT A REPORT BY JOHN LORD (SEPT. 30, 1912) STATES THAT WIDTHS OF FOUR VEINS ON THE PROPERTY RANGE FROM 8 TO 18 FT. ESPENSHADE (1942) PRESUMES THAT THE EXPLORATORY DRILL HOLES WERE VERTICAL, AND THAT CONSEQUENTLY THE TRUE WIDTHS OF THE VEINS ARE NOT KNOWN. LENGTHS OF DRILL CORE COMPRISED OF MASSIVE SULFIDES IN THESE DRILL HOLES RANGED FROM 1.5 TO 62.5 FT.

Comments on development

  • DURING THE EARLY 1940'S, THE PROPERTY WAS CONTROLLED BY THE TUCKASEIGEE MINING COMPANY, WHICH WAS AFFILIATED WITH THE NORTH CAROLINA MINING COMPANY (WHICH OPERATED THE ADAMS COPPER MINE IN SWAIN COUNTY) AND THE OLIVINE PRODUCTS COMPANY. J.H. GILLIS WAS CONNECTED WITH THE THREE COMPANIES AND FURNISHED THE DRILL LOG ANALYSES TO ESPENSHADE.

Subject category Comment text
Deposit ESPENSHADE (1942) STATES THAT THE RELATIONSHIP OF THE PEGMATITE TO THE SULFIDE VEINS IS NOT KNOWN. ROSS (1935) APPARENTLY CONSIDERS THE PEGMATITE AS HAVING BEEN EMPLACED PRIOR TO SULFIDE MINERALIZATION, BECAUSE THE "...VEIN HAS DEVELOPED WITHIN SCHIST AS WELL AS WITHIN PEGMATITE." HE RAISES THE POSSIBILITY THAT "...THE DEEPSEATED MAGMA FROM WHICH THE PEGMATITE WAS DIFFERENTIATED ...GAVE OFF MATERIALS THAT PRODUCED THE SAVANNAH VEIN." BECAUSE THESE RELATIONS WERE NOT KNOWN FOR OTHER MICA-BEARING PEGMATITES IN THE REGION, HE ADMITS THAT THE RELATIONS BETWEEN THE SULFIDE VEIN AND THE PEGMATITE ARE PROBABLY COINCIDENTAL.
