Comments on the geologic information

  • WALLROCKS ARE DEFORMED, CRUMPLED, AND ALTERED. LIMESTONES ARE DARK GRAY, CHERTY, DOLOMITIZED, SILICIFIED, ADN IMPREGNATED WITH QUARTZ, JASPEROID AND CALCITE VEINS. SHALES ARE GREENISH TO BLACK, CARBONACEOUS, SILICEOUS, SERICITIC, KAOLIMITIC AND PULVERIZED. EFFECTS OF LIMONITIZATION ARE COMMON ON HOST ROCKS. ORE MINERALS ARE INTIMATELY ASSOCIATED WITH JASPEROID AND QUARTZ VEINS.

General comments

Subject category Comment text
Deposit MINERALIZED ZONE IS LOCATED IN ALTERED WALLROCKS. THE OXIDIZED ORE IS LIGHT COLOURED AND MORE FN'ABLE THAN THE UNOXIDIZED (BASE) ORE. IT LACKS SULFIDES AND CONTAINS SULFATES INCLUDING GYPSUM, SCORODITE, AND MELELTERITE.
Deposit GOLD IS NOT VISIBLE IN THE ORES, AND IS CONCENTRATED IN THE CARBON-RICH PORTIONS OF THE ALTERED ZONES. THE ORE IS SOFT AND PULVERIZED, LIGHT YELLOWISH OR GRAYISH IN COLOR. THE ORE IS FORMED BY THE IMPREGNATION AND REPLACEMENT OF THE WALLROCKS; AND THE FISSURE-FILLINGS ARE NEGLIGIBLE. NEVERTHELESS THESE FISSURES WERE OF FUNDAMENTAL IMPORTANCE IN LOCALIZING THE DEPOSITS. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV
