Jan 04, 2012 (A Wilson) - Graphite occurs along a strike length in excess of 2,100 metres (6,900 feet). Indicated widths along part of the mineralized zone are sufficient to be amenable to open pit mining methods. The width of the deposit ranges from 20-60 m.

Jan 04, 2012 (A Wilson) - Three zones of mineralization have been identified. Within the mineralized zone(s), graphite occurs as seams or laminae of fine to coarse flakes in bands of varying concentrations estimated to run from less than one percent to more than 10 percent. This zone also carries appreciably more pyrite than the graphite-barren gneisses and often presents a friable, dark brown to black coloured "burn" on outcrop surfaces. Diamond drilling returned the following results: DDH 82-1: values ranging from 0.16% graphite over 6 feet to 1.16% graphite over 10 feet; DDH 82-12: values ranging from 0.48% graphite over 10 feet to 1.24% graphite over 10 feet; DDH 82-3: values ranging from 0.28% graphite over 10 feet to 2.26% graphite over 10 feet; DDH 82-4: values ranging from 0.5% graphite over 10 feet to 1.52% graphite over 10 feet. Results from the two bulk samples ranged from 1.71% graphite to 2.65% graphite.
