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) assumptions relating to recovered grade, average ore recovery,
internal dilution, mining dilution and other mining parameters set out in the Feasibility Study or Optimization Study; (v) assumptions relating to gross
revenues, operating cash flow and other revenue metrics set out in the Feasibility Study or Optimization Study; (vi) mine expansion potential and expected
mine life; (vii) expected time frames for completion of permitting and regulatory approvals and making a production decision; (viii) the expected time
frames for the construction of a mining grade road by Stornoway and completion generally of the Route 167 extension and the financial obligations or costs
incurred by Stornoway in connection with such road extension; (ix) future exploration plans; (x) future market prices for rough diamonds; and (xi) 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 Stornoway’s ability to achieve its 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) required capital investment and estimated workforce requirements; (ii) estimates of net present value and internal rates of return;
(iii) receipt of regulatory approvals on acceptable terms within commonly experienced time frames; (iv) the assumption that a production decision will be
made, and that decision will be positive; (v) anticipated timelines for the commencement of mine production; (vi) anticipated timelines related to the
construction of a mining grade road by Stornoway and completion generally of the Route 167 extension and the impact on the development schedule at
Renard; (vii) anticipated timelines for community consultations and the impact of those consultations on the regulatory approval process; (viii) market
prices for rough diamonds and the potential impact on the Renard Project’s value; and (ix) future exploration plans and objectives. Additional risks are
described in Stornoway's most recently filed Annual Information Form, annual and interim MD&As, 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

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.

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.

Stornoway recently completed a successful 5,000
tonne bulk sample at Renard 65 in July 2012.
Diamond recovery of 963 carats with a March 2013
valuation of US$180/ct (with sensitivities of $203 & $169).
July 2013: Conversion of Inferred Mineral Resources
to a depth of 150m to an Indicated Mineral Resource
of 2.30 Mcarats (comprising 7.87 Mtonnes at 29cpht)
Upon conversion to a Mineral Reserve, this material
may be incorporated into the mine plan in two ways:
1. add 1 year to the LOM and increase the
production rate to 2.5Mt/a or
2. add 3 years to the LOM as a reserve tail at a
production rate of 2.1Mt/a
The cost of developing a 75m deep pit at Renard 65
is already contained within the Feasibility Study.
The Renard 65 bulk sample returned the highest
value diamonds to date at the Renard Project

The Renard kimberlite pipes have similar, but marginally different diamond populations exhibiting
coarse size distributions and with high proportions of large white gems. No fancy colours.
