Dec 07, 2005 (G Meyer) - The J- Zone is comprised of up to 3 sub-parallel quartz veins, striking at 83 over an exposed distance of 142 m and dipping at approximately 30 to the south. . The overall width of the quartz-vein system is up to 3 m. At the eastern end of the exposed area the strike changes to 53 , apparently due to faulting and dragging on fault planes.

Dec 07, 2005 (G Meyer) - The J-Zone is comprised of up to 3 sub-parallel quartz veins, which pinch and swell over an exposed distance of 142 m. The southern-most quartz vein is the widest and ranges in thickness up to 1.2 m. In addition, there are numerous small quartz veins. The overall width of the quartz-vein system is up to 3 m.
Dec 07, 2005 (G Meyer) - In the east, the quartz veins occur in relatively unaltered mafic volcanic rock. Carbonatization increases to the west and so does the presence of arsenopyrite.
