Mar 25, 2010 (D Draper) - A 12.3 ft (3.7m) section of carbonaceous sediment encountered in hole 179-9 returned an average gold value of 0.64 dwt/t (1.09 g/t) across the whole unit, including a sample which assayed 1.56 dwt/t over 1.7ft (2.67 g/t over 0.52m). Hole 179-5 was collared 122m east of 179-9. A 0.52m section of quartz veining within an intermediate tuff returned 0.96 dwt/t Au (1.65 g/t). Arsenopyrite, pyrite, chalcopyrite and sphalerite were noted in association with the vein. Hole 179-30, collared 100m north of 179-5, intersected intermediate to felsic tuff and carbonaceous sediment which returned gold values up to 0.058 oz./t over 4.92ft (2 g/t over 1.5m). This sample was contained within a 5.6m section which averaged 1.3 g/t Au over its length. Hole 179-31 was collared approximately 250m WNW of 179-5 and assayed 0.119 oz/t (4.1 g/t) over 1.5m within intermediate to felsic tuff. All four holes were drilled bearing az180 deg. (T-2447)
