Jun 24, 2013 (G Seim) - DDH 96-317 was drilled on an azimuth of 344ºwith an inclination of -50º. The hole collared at 68 m in grey carbonate rock. The rock grades to talc-chlorite schist by 90.5 m and returns to grey carb rock by 141.4 m. Quartz-carbonate alteration was logged from 161.25 m to 163.20 m. The mineralized zone is marked by anastomosing quartz and quartz- carbonate veinlets at irregular orientations and contains 5% to 6% disseminated 3 mm to 8 mm subhedral crystals of pyrite. The hole continued in grey carbonate rock cut by occasional feldspar porphyry dikes to a depth of 220 m after which the rock graded to talc-chlorite schist. The end of the hole was at 269.99 m in talc-chlorite schist.
