Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives,assumptions or future events or performance (often, but not always, using words or phrases such as “expects”, “anticipates”, “plans”, “projects”,“estimates”, “assumes”, “intends”, “strategy”, “goals”, “objectives” or variations thereof or stating that certain actions, events or results “may”,“could”, “would”, “might” or “will” be taken, occur or be achieved, or the negative of any of these terms and similar expressions) are not statementsof historical fact and may be forward-looking statements.Forward-looking statements are made based upon certain assumptions and other important factors that, if untrue, could cause the actual results,performances or achievements of Stornoway to be materially different from future results, performances or achievements expressed or implied bysuch statements. Such statements and information are based on numerous assumptions regarding present and future business strategies and theenvironment in which Stornoway will operate in the future, including the price of diamonds, anticipated costs and ability to achieve goals. Certainimportant factors that could cause actual results, performances or achievements to differ materially from those in the forward-looking statementsinclude, but are not limited to: (i) estimated completion date for the Environmental and Social Impact Assessment; (ii) required capital investmentand estimated workforce requirements; (iii) estimates of net present value and internal rates of return; (iv) receipt of regulatory approvals onacceptable terms within commonly experienced time frames; (v) the assumption that a production decision will be made, and that decision will bepositive; (vi) anticipated timelines for the commencement of mine production; (vii) anticipated timelines related to the Route 167 extension and theimpact on the development schedule at Renard; (viii) anticipated timelines for community consultations and the conclusion of an Impact andBenefits Agreement; (ix) market prices for rough diamonds and the potential impact on the Renard Project’s value; and (x) future exploration plansand objectives. Additional risks are described in Stornoways most recently filed Annual Information Form, annual and interim MD&A, and otherdisclosure documents available under the Company’s profile at: www.sedar.com.When relying on our forward-looking statements to make decisions with respect to Stornoway, investors and others should carefully consider theforegoing factors and other uncertainties and potential events.

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.
  32. 32. 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.

  33. 33. 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.
