Geological Summary |
NICOLA GROUP AUGITE ANDESITE AND LESSER AGGLOM- ERATE IS INTRUDED BY MONZONITE PORPHYRY RELATED TO THE THUYA BATHOLITH AND OVERLAIN BY EXTENSIVE (TERTIARY) BASALT FLOWS. SURFACE EXPOSURES ARE POOR. VEIN STRUCTURES DIP NORTHEAST 40 TO 60 DEGREES. TRANSVERSE STRUCTURES CAUSE VEINS TO PINCH AND SWELL. ALTERATION RANGES FROM PERVASIVE PROPYLITIZATION TO RARE SILICIFICATION. MINERAL- IZATION CONSISTS OF PYRITE DISSEMINATED IN CARB- ONATE ALTERED VOLCANICS AND MONZONITE, AND LESS COMMONLY, CHALCOPYRITE IN QUARTZ-CARBONATE VEIN STRUCTURES. VEIN STRUCTURES CONTAIN VARIABLE GOLD AND SILVER VALUES.
