Jan 12, 2015 (A Wilson) - The main flake-graphite occurrence is several metres thick and dips to the southeast at 45-50° and plunges down to the northeast and southwest. It was trenched to approximately 5 m and is truncated by an amphibolite gneiss dyke to the northeast. The Discovery Zone has now been traced for over 600 m.

Jan 12, 2015 (A Wilson) - Grab samples collected from the site ranged from 8.7% to 69.1% graphite. A trench sample returned 36.8% graphite over 1.5 m. Metallurgical testing returned a graphite head grade of 34%. Both jumbo and large flake graphite were produced during the metallurgical tests. Highlights of the diamond drilling on the Discovery Zone were 2.40 Cg(%) over 2.68 m, including 7.35 Cg(%) over 0.61 m from BOB13-001. Drill hole BOB13-004 returned 6.36 Cg(%) over 3.38 m, including 8.22 Cg(%) over 2.44 m and 31.90 Cg(%) over 0.53 m. The Discovery Zone has also retuned assays of 36.8 Cg(%) over 1.5 m in a channel sample, 20.2% Cg(%) over a 1.4 m channel sample, 14.6 Cg(%) over 0.7 m channel sample, 8.7 Cg(%) over 0.5 m Cg(%)and 7.8 Cg(%) from a 0.3 grab sample.
