Oct 25, 2010 (A Wilson) - Diamond drilling intersected a sequence of intermediate to felsic tuffs, quartz-eye felsic tuff, crystal tuff and interflow metasediments. All units are intruded by narrow quartz-feldspar porphyry sills/dikes. Two graphitic horizons were also intersected one at 76.5 m and the other at 175.5 m. The drill hole terminated in what was described as a felsic fragmental unit.
