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.

Québec, with respect to future project debt financing. The Credit Support Agreement has an annual commitment fee of 175 bps undrawn, and will take the form of a direct project loan ranking
pari passu with concurrent senior lenders or, as appropriate, on a stand alone basis on terms no less favourable than prevailing commercially reasonable market terms.

Renard is Continuing to Grow
Renard 65 Bulk Sample: Expansion in the Project Reserve
Renard 65
Stornoway commenced a 5,000 tonne bulk sample at Renard 3
Renard 65 in July 2012.
The objective is the recovery of a 1,000 carat parcel of
diamonds for valuation, to allow conversion of Inferred
Resources to Reserve.
Renard 65 currently contains:
• 3.7 mcarats of Inferred Mineral Resources
(12.9mtonnes at 29 carats per hundred tonnes)
• 6.8 to 13.7 mcarats of Exploration Target (29.5 to 41.6

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.
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.)

The Renard NI 43-101 compliant Mineral Resource of January 2011 and the Feasibility Study of November
2011 utilize 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

Future Rough Diamond Production is Forecast to be Static
Almost all rough diamond production forecasts show flat or declining
production long term. Rough production may not reach 2008 levels in
carat terms again. Only 15% Supply
Growth
No large scale diamond mine has been discovered since the
2010-2020
discovery of EKATI and Diavik in the early 1990s. New production
from projects under development such as Renard 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.

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.

Financial Analysis
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.
