29Notes: The potential quantity and grade of any exploration target (previously referred to as “potential mineral deposit”) is conceptual in nature, and it is uncertain if further explorationwill result in the target being delineated as a mineral resource. The exploration upside for the Renard kimberlite pipes has been determined by projecting reasonable kimberlitevolumes from the base of the Inferred Resource to a depth of 700m below surface. In the case of the Lynx and Hibou dykes, the exploration upside was established on the basis ofknown drill intersections of kimberlite for which insufficient diamond sampling exists to adequately estimate a diamond resource grade.KimberliteGrade(cpht)Tonnes(millions)Contained Carats(Millions)Renard 2 103 to 188 4.0 to 4.6 4.1 to 8.6Renard 3 107 to 168 0.8 to 1.6 0.8 to 2.8Renard 4 38 to 79 11.1 to 15.3 4.2 to 12.1Renard 9 45 to 50 3.9 to 6.3 1.7 to 3.2Renard 65 23 to 33 29.5 to 41.6 6.8 to 13.7Lynx Dyke 96 to 120 3.1 to 3.2 3.0 to 3.8Hibou Dyke 104 to 151 2.7 to 2.9 2.9 to 4.3Total ExplorationUpside55.1 to 75.5 23.5 to 48.5Renard Exploration UpsideAnnounced January 24th, 2011

This “Alternative” diamond price model is highly accretive to the project’svaluation given the dominance of Renard 2 in the mine plan. The interpretation of similarity in the diamondpopulations is the more conservative approach.
