NICOLA BELT (UPPER TRIASSIC) ALKALINE AND CALC- ALKALINE BASALTS AND DERIVED BRECCIAS AND TUFFS, AND MINOR SEDIMENTS, OCCUR WITHIN NORTHERLY TREND- ING FAULT BOUNDED BELTS. DIP ORIENTATIONS ARE GENERALLY STEEP AND TO THE WEST. THE VOLCANO- SEDIMENTARY ROCKS ARE INTRUDED AND PROPYLITISED BY COMAGMATIC COMPLEX ALKALINE PLUTONS OF SYENITIC TO GRABBROIC COMPOSITION. WIDESPREAD FRACTURE- CONTROLLED COPPER MINERALIZATION OCCURS IN ALTER- ATION ZONES. GOLD OCCURS LOCALLY IN FRACTURED, ALTERED VOLCANICS AND SEDIMENTS. MAGNETIC HIGHS APPARENTLY COINCIDE WITH DIORITE INTRUSIONS. A BROAD MAGNETIC LOW CORRELATES WITH A TROUGH OF PYRITIC, CALCAREOUS ARGILLITES. I.P. SURVEYING EXTENDED TWO PREVIOUSLY KNOWN ANOMALOUS ZONES.
