    Extensive test work was performed in the past on the Bissett Creek graphitic gneiss including bulk sampling, pilot
    plant tests and laboratory work. Many avenues were tested and the consistent result was the high recovery of
    graphite during processing demonstrating the potential for recovering a significant percentage of the large crystal
    flakes in the +48 mesh fraction.
    During the summer of 2007, in addition to the independent drill program, SGS carried out validation tests on the
    recovery of graphite and especially the large flakes. This was first done at CFP, a processing laboratory in Val d’Or,
    Quebec and then assays were done at the COREM facilities in Quebec City. The tests were done on graphitic gneiss
    rock samples taken from the pit #1 location and acquired during SGS’s first site visit in June 2007. A second battery
    of tests was also performed at Ortech, with assays at Activation Laboratories Ltd. in Ontario, to further validate the
    results. The samples came from parts of the witness core samples housed at the mine site.
    These additional tests have allowed SGS to conclude that large flakes were present evenly in the various grades and
    locations drilled in 2007. The actual proven graphitic carbon recovery is in the 95% range. The actual flake size
    distribution before optimization showed approximately 30% in the +35 mesh size, 40% in the -35 to +48 mesh
    fraction and 30% in the – 48 mesh portion.
