Renard’s Diamonds 13Valuation Conducted by WWW International Diamond Consultants Ltd. May 8th-13th, 2011 Renard kimberlite pipes have a diamond population with a coarse size distribution and high proportion of large white gems. Lynx and Hibou kimberlite dykes have a finer distribution of browner stones. 99% by weight gem/near-gem quality. 1% industrial quality boart. Coarse size distribution: potential for significant “Specials”, not accounted for in the current resource work. (Three to six 50-100ct stones and one to two +100ct stones every 100,000 carats.)

All samples utilize a +0.85mm (+1 DTC) cutoff.
32Financial AnalysisRenard Diamond Valuation SensitivitiesWWW determine High and Minimum sensitivities on their Base Case diamond price model. WWW state thatit is unlikely that an actual diamond price achieved for each kimberlite body upon production would fall belowthe “Minimum” sensitivity, but it is possible that the actual diamond price achieved may be higher than the“High” sensitivity, which is not a maximum price.The Feasibility Study Base Case diamond price of US$182/carat for Renard 2 and 3 and US$164/carat forRenard 4 derives from a value modeling approach that assumes a single diamond size distribution in thethree kimberlites.An alternative interpretation, that each kimberlite’s diamond population is unique and is correctly representedby its diamond sample, yields diamond price models of US$208/carat for Renard 2, US$165/carat for Renard3 and US$112/carat for Renard 4.

33Financial AnalysisRenard Diamond Valuation SensitivitiesThis “Alternative” diamond price model is highly accretive to the project’s valuation given the dominance ofRenard 2 in the mine plan.
