Comments on the geologic information

  • GOLD IN PYRITE ALONG BANDED FINE GRANULAR WHITE QUARTZ VEINS IN BASALT; ALSO FOUND WITH BISMUTHITE AND MOLYBDENITE. SHEAR ZONES FILLED WITH QUARTZ VEINS (TRENDS OF VEINS N70E). MINOR STRUCTURES ASSOCIATED WITH VEINS INCLUDE DRAG FOLDS AND SMALL NORTH-SOUTH FAULTS WITH VISIBLE HORIZONTAL DISPLACEMENT. LIKELY A COMBINATION OF STRUCTURE AND FAVORABLE LITHOLOGY CONTROLLED ORE DEPOSITION. MINERALIZATION IN SHEARS BORDERING QUARTZ VEINS. VALUES COME FROM QUARTZ VEINS WITH ORDINARILY SHOW PYRITE CONCENTRATED ALONG DARK BANDS IN THE VEIN.
