Comments on the geologic information

  • WALLROCKS ARE HIGHLY SHATTERED, JOINTED AND BRECCIATED. LIMESTONES ARE DARKGRAY, CHERTY, DOLOMITIZED. SILICIFIED AND IMPREGNATED WITH VEINS OF CALCITE, QUARTZ AND JASPEROID. THE ALTERED ZONES ARE FINABLE AND OF LIGHT BUFF COLOUR. THIN BANDS OF SHATES ARE GOUND IN THICK LIMESTONE HORIZONS. THE SHALES ARE CRUMPLED, GRAY TO BLACK, CALCAREOUS, KAOLINITIC, CARBONACEOUS, AND SERICITIC. GHE WALLROCKS SHOW EFFECTS OF LIMONTIZATION. ORE MINERALS ARE UNTIMATELY ASSOCIATED WITH QUARTZ AND JASPEROID VEINS.

Subject category Comment text
Deposit THE ORE IS SOFT AND PULVERIZED, LIGHT YELLOWISH OR GREYISH IN COLOUR. GOLD IS NOT VISIBLE IN THE ORES, AND IS CONCENTRATED ONLY INT THE CARBON-RICH PORTIONS OF THE ALTERED ZONES. THE ORE IS FORMED BY THE IMPREGNATION AND REPLACEMENT OF THE WALLROCKS; AND THE FISSURE FILLINGS ARE NEGLIGIBLE. NEVERTHE LESS THESE FISSURES WERE OF FUNDAMENTAL INPORTANCE IN LOCALIZING THE DEPOSITS.
Deposit MINERALIZED ZONES ARE LOCALIZED IN ALTERED WALLROCKS. UNALTERED ROCKS ARE TOTALLY BARREIN. THE OXIDIZED ORE IS LIGHT COLORED AND MORE FORIABLE THAN UNOXIDIZED (BASE) ORE. IT LACKS SULFIDES AND CONTAINS SULFATES INCLUDING GYPSUM, SCORODITE AND MELENTERITE LIGHT COLORED AND MORE FORIABLE THAN UNOXIDIZED (BASE) ORE. IT LACKS SULFIDES AND CONTAINS SULFATES INCLUDING GYPSUM, SCORODITE AND MELENTERITE
