| Deposit | MINERALIZATION OCCURS IN NW STRIKING QUARTZ VEINS THAT RANGE IN WIDTH FROM A FEW INCHES TO 8 FEET. MANY OF THE VEINS DIP NE, BUT A FEW TEND TO BE VERTICAL. THE VEINS OCCUR IN BOTH THE DIORITE AND THE ARGILLITE. MINERALIZATION IS VERY MINOR IN THE QUARTZ MASSES, CONSISTING MOSTLY OF IRON OXIDE AND A FEW SMALL GRAINS OF GALENA. |
