Nov 30, 2015 (D Draper) - Hole S03-11 was drilled approx. 140m NE of S98-18 during the 2003/04 St. Andrew drill program. It returned 10.97 g/t Au over 1m at 114m from a unit of ultramafic metavolcanics cut by 50% quartz-carbonate veins and stringers. A carbonated mafic volcanic at 271.7m assayed an average of 2.34 g/t Au over 2.3m. Hole S03-12, collared 40m SW of 11, returned up to 2.97 g/t Au over 1m within a zone of intermixed ultramafic volcanic and feldspar porphyry.
Nov 30, 2015 (A Wilson) - Gold values ranging from 1.35 g/t Au over 1.5 m to 5.37 g/t Au over 1 m were returned from mafic metavolcanic rocks and quartz-feldspar porphyries in drill hole S98-18. Assays from DDH S-11-002 returned values up to 6.79 g/t Au over 1 m. DDH S-11-004 returned values of 3.22 g/t over 1 m of syenite. DDH S-11-005 returned values up to 1.44 g/t Au over 1 m in ultramafic schist.
