| Deposit | NORTHWEST STRIKING CROSS FAULTS ARE RELATIVELY BARREN OF MINERALIZATION. THE MINERALIZED OXIDATION ZONE (FOLLOWING NORTHEAST STRIKING FAULTS) RESTS ABOVE A SULPHIDE ZONE. ALL MINING IS DONE IN THE OXIDIZED ZONE (UP TO 80 METERS THICK). |
| Deposit | ARE OTHER ZN MINES IN VAZANTE AREA. |
| Deposit | WILLEMITE AND CALAMINE ORE BODIES ARE ASSOCIATED WITH FAULT BRECCIAS; CALAMINE ORES ALWAYS TO EAST OF WILLEMITE BODIES IN COLLAPSE BRECCIA. COPPER MINERALIZATION OCCURS AS SMALL VEINS, STRINGERS, AND BOXWORKS CONTAINING COVELLITE, GALENA, AND SPHALERITE CUTTING THE MAIN MINERALIZED FAULT ZONE. |
