General comments

Subject category Comment text
Deposit THE NW PORTION OF THE DEPOSIT (PHYLLITE SEQUENCE) HAS BEEN CUT BY SMALL GABBRO-DIABASE BODIES AND DIKES OF ALKALINE SYENITE PORPHYRIES. GRANITES ASSOCIATED WITH THE GOLD OCCURRENCES CROP OUT ON THE SURFACE AT 15 KM FROM THE DEPOSIT. THE ORE ZONE CAN BE TRACED FOR SEVERAL KM IN LENGTH AND IS CONCENTRATED IN THE HANGING OR FOOTWALL OF FINELY SHEARED PHYLLITES. THE ROCKS DISPLAY PLASTIC DEFORMATION CHARACTERISTICS, WHICH TOOK PLACE UNDER STATIC LOAD CONDITIONS. MASSIVE COARSELY CRYSTALLINE QUARTZ PREDOMINATES IN THE VEINS. THE RICHEST ORE OCCURS NEAREST THE ORE BODY CONTACTS WHERE BRECCIA STRUCTURES PREDOMINATE, THE POOREST ORES OCCUR IN THE INNER PORTIONS OF THE ORE BODIES, WHICH CONSISTS OF SULFIDE-POOR QUARTZ.
