Economic information

Ore body information

  • General form STRATABOUND
    Length 68M
    Width 37M

Controls for ore emplacement

  • Disseminated Pyrite And Quartz Stringers

Comments on the geologic information

  • FELSIC TUFF AND RHYOLITE IS BLEACHED AND FRACTURED IN METALLIZED AREAS. MAIN SHAFT FOLLOWS A QUARTZ STRINGER IN THIS ZONE. TINY PYRITE CUBES DISSEMINATED THROUGH THE SILICEOUS TUFF ARE THE ONLY INDICATIONS OF METALLIZATION. PYRITE IS PARTICULARLY ABUNDANT IN BLEACHED PORTIONS OF THE ROCK. GOLD WAS REPORTED IN THE QUARTZ STRINGER AND IN SEAMS IN THE MINERALIZED ZONE AND COUNTRY ROCK.uGOLD IS ROUGHLY STRATABOUND WITHIN FLOW BANDED RHYOLITE FLOW. DEPOSIT ISuSIMILAR TO LICK MOUNTAIN, NEAR ALBEMARLE (DOVER, UNC CHAPEL HILL THESIS) AND WITH THE RUSHuAND DOWD MINES IN THE BIRKHEAD MOUNTAINS NEAR ASHEBORO, N.C.
