Jan 09, 2015 (D Draper) - Hole 18668 (bearing az. 180, dip -50) gave results as follows: 0.017 oz/t Au over 5ft in mafic volcanics; 0.058 oz/t over 3.7ft from a fault zone; 0.270 oz/t Au over 3ft and 0.16 oz/t Au over 5.4ft from a unit called Greyzone in log (altered mafic metavolcanic?) mineralized with pyrite and trace pyrrhotite, chalcopyrite and sphalerite in stringers. Three other holes drilled in vicinity of 18668 also returned gold values: Hole 18669, collared approx. 185m east, assayed 0.024 oz/t Au over 5ft in graphitic argillite. Hole 18683, collared 145m west, assayed 0.024 oz/t Au over 4ft and 0.036 oz/t Au over 3ft from Greyzone units at top of hole. Hole 18684, collared 135m SW, assayed 0.032 oz/t Au over 4ft in a mafic volcanic.
