Analytical data

Result EDDY CREEK CHANNEL SAMPLE ASSAYED 1.4 OZ/TON AG, 0.10 % CU, 0.5 % PB, 0.40 % AS AND A TRACE OF AU. IT SHOULD BE NOTED THAT MINERALIZATION IS VERY ERATIC ON THE SURFACE AND THE SAMPLES CANNOT BE CONSIDERED AS BEING REPRESENTATIVE OF THE ENTIRE VEIN.

General comments

Subject category Comment text
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.
