- The document is Stornoway Diamond Corporation's annual report presentation for its shareholders meeting on May 15, 2018. - In 2017, Stornoway met its mining targets and achieved commercial production at its Renard Diamond Mine in Quebec. It also completed several milestones like the plant upgrade. - For 2017 results, Stornoway met its mining targets but had lower diamond prices and sales than projected, though production costs were lower than expected. It also spent more on capital than anticipated for the year.

2. Forward Looking Information
2
This presentation contains "forward-looking information" within the meaning of Canadian securities legislation. This information and these statements, referred to herein as “forward-looking statements”, are made as of
the date of this presentation and the Corporation does not intend, and does not assume any obligation, to update these forward-looking statements, except as required by law. Capitalized terms in these FLS not
otherwise defined in this presentation have the meaning attributed thereto in the most recently filed AIF of the Corporation.
These forward-looking statements include, among others, statements with respect to Stornoway’s objectives for the ensuing year, our medium and long-term goals, and strategies to achieve those objectives and goals,
as well as statements with respect to our beliefs, plans, objectives, expectations, anticipations, estimates and intentions. Although management considers these assumptions to be reasonable based on information
currently available to it, they may prove to be incorrect.
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 Reserves, 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, size distribution and quality of diamonds, average ore recovery, internal dilution, mining dilution and other mining parameters set out in the 2016 Technical Report as well as levels of diamond breakage;
(v) assumptions relating to gross revenues, cost of sales, cash cost of production, gross margins estimates, planned and projected capital expenditure, liquidity and working capital requirements; (vi) mine expansion
potential and expected mine life; (vii) the expected time frames for the ramp-up and achievement of plant nameplate capacity of the Renard Diamond Mine (viii) the expected financial obligations or costs incurred by
Stornoway in connection with the ongoing development of the Renard Diamond Mine; (ix) future market prices for rough diamonds; (x) sources of and anticipated financing requirements; (xi) the effectiveness, funding or
availability, as the case may require, of the Senior Secured Loan and the remaining Equipment Facility and the use of proceeds therefrom; (xii) the Corporation’s ability to meet its Subject Diamonds Interest delivery
obligations under the Purchase and Sale Agreement; and (xiii) the foreign exchange rate between the US dollar and the Canadian dollar. Any statements that express or involve discussions with respect to predictions,
expectations, beliefs, plans, projections, objectives, assumptions or future events or performance are not statements of historical fact and may be forward-looking statements.
Forward-looking statements are made based upon certain assumptions by Stornoway or its consultants 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 prospects and strategies and the environment in which Stornoway will operate in the future, including the recovered grade, size distribution and quality of diamonds, average ore recovery, internal
dilution, and levels of diamond breakage, the price of diamonds, anticipated costs and Stornoway’s ability to achieve its goals, anticipated financial performance. Although management considers its assumptions on such
matters to be reasonable based on information currently available to it, they may prove to be incorrect. Certain important assumptions by Stornoway or its consultants in making forward-looking statements include, but
are not limited to: (i) required capital investment (ii) estimates of net present value and internal rates of return; (iii) recovered grade, size distribution and quality of diamonds, average ore recovery, internal dilution,
mining dilution and other mining parameters set out in the 2016 Technical Report as well as levels of diamond breakage, (iv) anticipated timelines for ramp-up and achievement of nameplate capacity at the Renard
Diamond Mine, (v) anticipated timelines for the development of an open pit and underground mine at the Renard Diamond Mine; (vi) anticipated geological formations; (vii) market prices for rough diamonds and their
potential impact on the Renard Diamond Mine; and (viii) the satisfaction or waiver of all conditions under the Senior Secured Loan and the remaining Equipment Facility to allow the Corporation to draw on the funding
available under those financing elements.

3. Forward Looking Information (continued)

By their very nature, forward-looking statements involve inherent risks and uncertainties, both general and specific, and risks exist that estimates, forecasts, projections and other forward-looking statements will not be
achieved or that assumptions do not reflect future experience. We caution readers not to place undue reliance on these forward- looking statements as a number of important risk factors could cause the actual outcomes
to differ materially from the beliefs, plans, objectives, expectations, anticipations, estimates, assumptions and intentions expressed in such forward-looking statements. These risk factors may be generally stated as the
risk that the assumptions and estimates expressed above do not occur, including the assumption in many forward-looking statements that other forward-looking statements will be correct, but specifically include,
without limitation: (i) risks relating to variations in the grade, size distribution and quality of diamonds, kimberlite lithologies and country rock content within the material identified as Mineral Resources from that
predicted; (ii) variations in rates of recovery and diamond breakage; (iii) slower increases in diamond valuations than assumed; (iv) risks relating to fluctuations in the Canadian dollar and other currencies relative to the
US dollar; (v) increases in the costs of proposed capital, operating and sustainable capital expenditures; (vi) operational and infrastructure risks; (vii) execution risk relating to the development of an operating mine at the
Renard Diamond Mine; (viii) failure to satisfy the conditions to the funding or availability, as the case may require, of the Senior Secured Loan and the Equipment Facility; ( ix) developments in world diamond markets; and
(x) all other risks described in Stornoway’s most recently filed AIF and its other disclosure documents available under the Corporation’s profile at www.sedar.com. Stornoway cautions that the foregoing list of factors that
may affect future results is not exhaustive and new, unforeseeable factors and risks may arise from time to time.
Qualified Persons
The Qualified Persons that prepared the technical reports and press releases that form the basis for the presentation are listed in the Company’s AIF dated February 23, 2017. Disclosure of a scientific or technical nature
in this presentation was prepared under the supervision of M. Patrick Godin, P.Eng. (Québec), Chief Operating Officer. Stornoway’s exploration programs are supervised by Robin Hopkins, P.Geol. (NT/NU), Vice President,
Exploration. Each of M. Godin and Mr. Hopkins are “qualified persons” under NI 43-101.
Non-IFRS Financial Measures
This presentation refers to certain financial measures, such Adjusted EBITDA, Adjusted EBITDA margin, Average diamond price achieved, Cash Operating Cost per Tonne of Ore Processed, Cash Operating Cost per Carat
Recovered, Capital Expenditures and Available Liquidity, which are not measures recognized under IFRS and do not have a standardized meaning prescribed by IFRS.
“Adjusted EBITDA” and “Adjusted EBITDA Margin” are used by management and investors to assess and measure the underlying pre-tax operating performance of the Corporation and are generally regarded by
management as better measures to evaluate performance trends. “Adjusted EBITDA” is defined as net income (loss) before depreciation, interest and other financial (income) expenses, and income tax, adjusted for
impairment charges, unrealized gains and losses related to the changes in fair value of U.S. Denominated debt and other non-recurring or unusual items that are not reflective of the Corporation’s underlying operating
performance and/or unlikely to occur on a regular basis. “Adjusted EBITDA Margin” is the calculation of Adjusted EBITDA divided by total revenues. “Average diamond price achieved” is a measure used by the
Corporation to measure the value of diamonds sold into the market in the period, prior to adjustments to reflect the impact of the stream. This measure is used by management and investors as it reflects the average
diamond price achieved during the period and is more comparable to the average diamond price achieved by to other diamond producers. Average diamond price achieved is calculated based on reported revenues
adjusted for the amortization of deferred stream revenue, and remittances made to/from stream participants and gains or losses from revenue hedging activities divided by the number of carats sold in the period. “Cash
Operating Cost per Tonne Processed” and “Cash Operating Cost per Carat Recovered” are used by management and investors to measure the mine’s cash operating cost based on per tonne of ore processed or per carat
recovered. Cash Operating Cost Per Tonne Processed is calculated based on reported operating expenses adjusted for the impact of inventory variation, excluding depreciation, divided by tonnes of ore processed for the
period. Cash Operating Cost per Carat Recovered is the total cash operating cost divided by carats recovered. “Capital Expenditure” is the term used by the Corporation and investors to describe capital expenditures
incurred during the period. This measure is used by management and investors to measure the amount of capital spent by the corporation on sustaining, margin improvement, and/or growth capital projects in the
period. “Available Liquidity” comprises cash and cash equivalents, short-term investments and available credit facilities (less related upfront fees) and is used by the management and investors to measure the amount of
cash resources available to the Corporation, over and above the cash generated from operations, to support the operating and capital requirements of the business.

Premier sautage de production - décembre 2017
Premiers panneaux de production développés
dans la kimberlite à faible teneur et fortement
diluée située à la limite nord de la cheminée au
niveau 290m.
La teneur devrait augmenter à mesure que
l'exploitation minière progresse vers le centre de
la kimberlite.
Premières expériences :
Roche encaissante plus compétente et kimberlite
moins compétente que prévu.
Les chantiers sautés s’affaissent naturellement
Méthode de minage se développera de « Blasthole
Shrinkage » vers « Assisted Block Cave » (ABC).
Toutes les infrastructures pour ABC sont en place
Opportunité pour des coûts de développement
moindre à long terme et élimination du
remplissage planifié a partir de la surface.

Usine de tri du minerai
Conçu pour réduire la quantité de stériles dans
l'alimentation du minerai. Utilise l'analyse spectrale sur
l'alimentation primaire + 30mm -200mm.
Plusieurs étapes
La première étape du tri est de rejeter le stérile.
La deuxième étape (récupération) consiste à extraire la
kimberlite du flot de rejets et à la retourner à l'usine.
Retombées
Améliore l’efficacité du concassage et la préservation du
diamant.
Augmente la capacité nominale de l’usine.
Réduit l'usure à l’usine et prolonge la vie des composantes.
Améliore la qualité de la kimberlite traitée pour en disposer.
La mise en service a débuté le 25 mars; traitement
consistent depuis fin avril.
Le volume et la qualité de la ségrégation minerai/stérile ont
été positifs et les résultats initiaux de récupération des
diamants encourageants.

1. Additional resources include tailings retreatment, which could be viable in older mines as run-of-mine is depleted, early-stage projects and projects currently marginal, which may become viable as rough prices increases

- Approvisionnement minier normal à négatif attendu à long terme

36. Le future : Épuisement des mines de diamant, 2018-2025
La plus grande mine de diamant individuelle (Argyle) et les deux plus grosses
mines canadiennes de diamant devraient être épuisées à partir de 2020.
