Comments on the geologic information

  • THERA ARE TWO MAIN TYPES OF ARE; CARBONATE ORE AND FLOW ORE. CARBONATE ORE IS COMPOSED OF BRECIATED CARBONATE FRAGMENTS IN A STOCKWORK OF WHITE QUARTZ. GOLD MINERALIZATION IS ERRATIC AND IS OFTEN COARSE AND FREE. SULFIDE ASSOCIATION IS RARE IN THE ORE. FLOW ORE OCCURS IN COMPETENT CARBONATED FLOWS AND INCOMPETENT INTER- LAYERED TUFFS. GOLD MINERALIZATION IS ASSOCIATED WITH PYRITE
