Long Term Business Plan
Stornoway has also developed a Long Term Business
Plan (“LTBP”) based on the Project’s total Indicated and
Inferred Mineral Resources to a depth of 700m.
This material is within the scope of the mine
infrastructure costed within the Feasibility Study, and
includes 6.1 Mcarats of high grade Inferred Mineral
Resources between 600-700 meters depth in Renard 2.
The LTBP also contemplates an increased production
rate within the scope of the process plant’s design
parameters, which allows for expansion up to 7,000
tonnes per day (2.6 Mtonnes/annum).
Expansion mill feed is expected to be derived from the A 4 carat, top quality diamond
open pit on the Renard 65 kimberlite. recovered from Renard 65 drillcore
Although highly accretive, the project’s Inferred Mineral
Resources are not included in the Feasibility Study
economic analysis in accordance with NI 43-101.
The LTBP is the basis of the Renard mine permit
application, and as such forms part of the project’s
public disclosure in connection with the environmental
assessment regulatory process under applicable federal
and provincial legislation.

Permitting
On-Track for Completion in 2012
Renard falls under the environmental protection regime
of the James Bay and Northern Québec Agreement
(JBNQA) and the Canadian Environmental Assessment
Act.
Stornoway filed the Renard Environmental and Social
Impact Assessment (ESIA) with Québec and federal
regulators in December 2011.
Public consultations under the auspices of the federal
regulator where held in Chibougamau and Mistissini
between June 5th and 7th. Hearings under the auspices
of the Review Committee of the JBNQA are expected
to be held later in the summer, with the project
becoming eligible for its Certificates of Authorization
thereafter.
The Renard ESIA describes a limited-footprint project
with modest impacts on the local environment, all of
which are well within existing Québec and federal
standards.
Stornoway has published the complete ESIA, the
Environmental Baseline Study, and the project Closure
Plan online.

The “Mecheshoo” Agreement (IBA)
Renard’s Social Licence
The Renard Diamond Project is situated close to the
Cree Nation of Mistissini (CNM) and the mining
community of Chibougamau.
Stornoway and its predecessor companies have
conducted extensive community consultations in
Mistissini since 2001 on the basis of respect,
transparency and full regulatory compliance.
In March 2012 Stornoway concluded an Impacts and
Benefits Agreement, the “Mecheshoo Agreement”, with
the CNM and the Grand Council of the Crees (EI).

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.

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.

Upside

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.
