Forward-Looking Information

 This presentation contains "forward-looking information" within the meaning of Canadian securities legislation and “forward-looking statements”
 within the meaning of the United States Private Securities Litigation Reform Act of 1995. This information and these statements, referred to herein
 as “forward-looking statements”, are made as of the date of this presentation and the Company does not intend, and does not assume any
 obligation, to update these forward-looking statements, except as required by law.

 Forward-looking statements relate to future events or future performance and reflect current expectations or beliefs regarding future events and
 include, but are not limited to, statements with respect to: (i) the amount of mineral resources and exploration targets; (ii) the amount of future
 production over any period; (iii) net present value and internal rates of return of the mining operation; (iv) capital costs and operating costs; (v) mine
 expansion potential and expected mine life; (vi) expected time frames for completion of permitting and regulatory approvals and making a
 production decision; (vii) future exploration plans; (viii) future market prices for rough diamonds; and (ix) sources of and anticipated financing
 requirements. 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 statements
 of 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 by
 such statements. Such statements and information are based on numerous assumptions regarding present and future business strategies and the
 environment in which Stornoway will operate in the future, including the price of diamonds, anticipated costs and ability to achieve goals. Certain
 important factors that could cause actual results, performances or achievements to differ materially from those in the forward-looking statements
 include, but are not limited to: (i) estimated completion date for the Environmental and Social Impact Assessment; (ii) required capital investment
 and estimated workforce requirements; (iii) estimates of net present value and internal rates of return; (iv) receipt of regulatory approvals on
 acceptable terms within commonly experienced time frames; (v) the assumption that a production decision will be made, and that decision will be
 positive; (vi) anticipated timelines for the commencement of mine production; (vii) anticipated timelines related to the Route 167 extension and the
 impact on the development schedule at Renard; (viii) anticipated timelines for community consultations and the conclusion of an Impact and
 Benefits Agreement; (ix) market prices for rough diamonds and the potential impact on the Renard Project’s value; and (x) future exploration plans
 and objectives. Additional risks are described in Stornoway's most recently filed Annual Information Form, annual and interim MD&A, and other
 disclosure 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 the
 foregoing factors and other uncertainties and potential events. Stornoway does not undertake to update any forward-looking statement, whether
 written or oral, that may be made from time to time by Stornoway or on our behalf, except as required by law.

Notes: Grades illustrated are for Indicated and Inferred Mineral Resources respectively at a +1DTC sieve size cut-off. Reserve and Resource categories are compliant with the "CIM Definition
Standards on Mineral Resources and Reserves". Mineral resources that are not mineral reserves do not have demonstrated economic viability. The potential quantity and grade of any Exploration
Target (previously referred to as a “Potential Mineral Deposit”) is conceptual in nature, and it is uncertain if further exploration will result in the target being delineated as a mineral resource.

    Announced July 23rd, 2012.

     Stornoway will commence the process of converting
     the project’s Inferred Mineral Resources with a 5,000
                                                                                                             Existing R65 Pit           Northern R65 Contact
     tonne bulk sample of the Renard 65 kimberlite,
     starting in July 2012.

     Renard 65 has a good potential to return large
     diamonds, and it is expected that 1,000 carats will
     be recovered for valuation.
                                                                                                                                             5,000t Trench
     Ore will be trenched from the northern end of
     Renard 65 where kimberlite is already exposed at
     surface. Processing will occur at the 10 tph plant
     located at the project site, with diamond recovery at
     Stornoway’s North Vancouver facility.
                                                                                                           A 4 carat, top quality diamond
     Conversion of Renard 65 will allow an increase in                                                     recovered from Renard 65 drillcore
     planned production rate to 7,000 tonnes per day (2.6
     Mtonnes/annum) and an extension of the project’s
     mine life and reserve tail.

     Results are expected by year end.

                                                                                                                                                              16
Renard’s Diamonds
Valuation 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.

  Global Rough Diamond Production Forecast

        Almost all rough diamond production forecasts show flat or declining production long term.

        Alrosa is an optimistic forecaster, with a 23% increase in carat supply 2010 to 2020. Others (such as RBC
        below) forecast 15-17% supply growth. Rough production may not reach 2008 levels in carat terms again.

        No large scale diamond mine has been discovered since the discovery of EKATI and Diavik in the early
        1990s. New production from projects under development is not expected to materially impact overall supply.

   The Renard Feasibility Study of November 2011, consistent with the NI 43-101 compliant Mineral Resource of January 2011, utilizes a higher diamond price based on an analysis of
  diamond breakage and poor plant recovery of the Renard 4 valuation sample, which is $164/carat. All samples utilize a +0.85mm (+1 DTC) cutoff.

                                                                                                                                                                                       44
 Financial Analysis
 Renard Diamond Valuation Sensitivities

  WWW determine High and Minimum sensitivities on their Base Case diamond price model. WWW state that
  it is unlikely that an actual diamond price achieved for each kimberlite body upon production would fall below
  the “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 for
  Renard 4 derives from a value modeling approach that assumes a single diamond size distribution in the
  three kimberlites.

  An alternative interpretation, that each kimberlite’s diamond population is unique and is correctly represented
  by its diamond sample, yields diamond price models of US$208/carat for Renard 2, US$165/carat for Renard
  3 and US$112/carat for Renard 4.

Renard Diamond Valuation Sensitivities

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

A real-terms diamond price growth factor of 2.5% per annum has been applied between 2012 and 2025.
This is consistent with well constrained rough diamond supply and demand forecasts and industry best-
practice. WWW have advised that Stornoway’s assumptions on diamond price and diamond price growth
are “reasonable in the context of the overall supply and demand environment” of the diamond industry.
The project shows strong sensitivity to future diamond price growth.

 Notes: 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 exploration
 will result in the target being delineated as a mineral resource. The exploration upside for the Renard kimberlite pipes has been determined by projecting reasonable kimberlite
 volumes 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 of
 known drill intersections of kimberlite for which insufficient diamond sampling exists to adequately estimate a diamond resource grade.

Processed Kimberlite Containment

  PKC site selection was based on a
  comprehensive evaluation of 5 sites.

  Geochemical characterisation of Processed
  Kimberlite (“PK”) and country rock waste
  indicates minimal metal leach potential and
  no acid generation.

  PKC facility will be a dry stacked facility with
  no requirement for a liner.                                  Dewatered PK                          Characterisation

  PKC facility can accommodate all current
  Indicated and Inferred Resources (44.3 Mt).

  Waste rock can be used as construction
  aggregate.

  PK will be de-watered by centrifuge and
  trucked to the PKC site. PKC is an
  engineered facility requiring compaction of
  berms and placement of erosion barriers.
  The PK deposition plan allows for
  progressive rehabilitation and re-vegetation.

  No fish habitat will be impacted by PK
  disposal.

Water Management

  All water in contact with mining materials will be collected and treated prior to release. Treated water will
  meet standards defined by Québec MDDEP Directive 019, Québec environmental effluent objectives for
  the protection of aquatic life, and the Canadian Metal Mining Effluent Regulation.
 Single watershed impacted by all mining activities.

 Water recycling for process plant.

 Water management system includes a network of collection ditches, a
 pumping network, a catch basin sump at Renard 65, a water
 treatment plant, and submerged discharge within Lake Lagopede                                   Wastewater Treatment Plant

Closure Plan

Stornoway acknowledges that it is only a temporary
user of land that will be returned to its traditional
users at the end of mine life. In this context, project
design has prioritized minimal environmental
footprint and progressive rehabilitation.

Buildings have been designed and materials
selected to facilitate dismantling, recycling and site
re-vegetation at the end of the mine life.

Mine planning ensures that all waste rock will be
used for construction, backfill of the underground
                                                          Before
mine. Open-pits will be flooded to create new fish
habitats.

PKC facility has been designed to ensure
progressive re-vegetation and ease of maintenance
during operations.

Benches will be progressively rehabilitated.

Airstrip will either be rehabilitated or vested to
authorities to become a regional infrastructure.

Post-closure environmental monitoring program will
be implemented.                                            After
