- The corporate update provides an overview of Stornoway Diamond Corporation's Renard Diamond Project in Quebec, including construction progress, key performance indicators, capital structure, and an updated mine plan from March 2016. - Construction is ahead of schedule and under budget. The forecast cost to complete is $775 million, less than the initial $811 million plan. Mining activities have extracted over 8.9 million tonnes of ore, exceeding targets. - The updated mine plan estimates a 14-year mine life producing 22.3 million carats of diamonds. Average annual production is forecast at 1.8 million carats for the first 10 years. Commercial production is expected to begin by the end of 2016.

1. Corporate Update, June 16, 2016

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. These forward-looking statements include, among others, 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) assumptions relating to recovered grade, average ore recovery, internal dilution, mining dilution and other mining parameters set out in the March 2016 Updated Renard Mine Plan and Mineral Reserve
Estimate; (iv) assumptions relating to gross revenues, operating cash flow and other revenue metrics set out in the 2016 Updated Renard Mine Plan and Mineral Reserve Estimate; (v) mine expansion potential and expected mine life; (vi) the expected time frames for the
completion of construction, start of mining and commercial production at the Renard Diamond Project and the financial obligations or costs incurred by Stornoway in connection with such mine development; (vii) the expected time frames for the completion of the open pit
and underground mine at the Renard Diamond Project; (viii) future market prices for rough diamonds; and (ix) future market prices for liquefied natural gas and diesel. All statements, other than statements of historical fact regarding Stornoway or the Renard Diamond Project,
are forward-looking statements. 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”, “schedule” 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 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 price of diamonds, anticipated costs and Stornoway’s ability to achieve its goals, regulatory developments, development plans, exploration, development and mining activities and commitments. 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) the amount of
future production over any period; (iii) assumptions relating to recovered grade, average ore recovery, internal dilution, mining dilution and other mining parameters set out in the March 2016 Updated Renard Mine Plan and Mineral Reserve Estimate ; (iv) assumptions relating
to gross revenues, operating cash flow and other revenue metrics set out in the 2016 Updated Renard Mine Plan and Mineral Reserve Estimate ; (v) estimates of net present value; (vi) anticipated timelines for completion of construction, commencement of mine production
and development of an open pit and underground mine at the Renard Diamond Project, (vii) anticipated geological formations; (viii) Stornoway’s interpretation of the geological drill data collected and its potential impact on stated Mineral Resources, Mineral Reserves, and
mine life; and (ix) Stornoway’s ability to draw on the financing elements of the Renard Diamond Project Financing Transactions closed on July 8th, 2014.
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, kimberlite lithologies and country rock content within the material identified as Mineral Resources from that predicted; (ii) variations in rates of recovery and
breakage; (iii) changes in development or mining plans due to changes in other factors or exploration results; (iv) slower increases in diamond valuations than assumed; (v) risks relating to fluctuations in the Canadian dollar and other currencies relative to the US dollar; (vi)
increases in the costs of proposed capital and operating expenditures; (vii) increases in financing costs or adverse changes to the terms of available financing, if any; (viii) tax rates or royalties being greater than assumed; (ix) risks relating to the receipt of regulatory approvals;
and (x) the additional risks described in Stornoway's most recently filed Annual Information Form, annual and interim MD&A and Stornoway's anticipation of and success in managing the foregoing risks. Stornoway cautions that the foregoing list of factors that may affect future
results is not exhaustive, and new, unforeseeable risks may arise from time to time.

WWW Rough Diamond Price Index, 2004-2016 (RoughPrices.com)
Mine Plan Financial Analysis assumes a 2.5% real terms diamond price escalation
between 2016 and 2028
The Renard Streaming Agreement includes a payment of US$56 per carat on 20%
of ROM production from Renards 2,3,4,9 and 65, Life-of-mine, escalating at 1%
per annum after the 3rd anniversary of production, inclusive of marketing costs.
1. As determined WWW International Diamond Consultants Ltd. at a +1 DTC sieve size cut off.
2. As determined by applying the world average rough price index of roughrices.com to the March 2014 price models, at a +1
DTC sieve size cut-off.
3. Should the Renard 4 diamond population prove to have a size distribution equal to the average of Renard 2 and 3, WWW
have estimated that a base case diamond price model of US$155 per carat would apply based on March 2014 pricing,
equivalent to US$126 per carat on a market price adjusted basis to March 2016.
The weighted average price of the March 2016 Probable Mineral Reserve is
US$155/ct, or C$209/ct, in March 2016 terms
Average life-of-mine pricing is US$185/ct or C$250/ct, or US$159/ct or

35. Diamond Sales
Stornoway will sell 100% of the Renard diamond
production by tender sale in Antwerp on an
undivided basis.
Stornoway has engaged well known diamond
industry broker and rough distributor Bonas-Couzyn
as sales commissionaire and tender agent for arm's
length market sales.
Other than under exceptional circumstances,
Stornoway will sell 100% of what it produces, will not
carry a stockpile outside of normal goods-in-progress,
and will be a market price taker.
Stornoway will support the Québec or Canadian
brand identification initiatives of its clients through
chain of custody certification.
First sales are expected in January 2017.

36. Exploration & Adamantin
Stornoway maintains an active diamond
exploration team and conducts 100%
owned generative programs.
Recent drilling at Adamantin Project
returned kimberlite in 18 of 78 holes
testing 72 geophysical targets interpreted
as 11 discrete kimberlite bodies.
Intersections of undiluted (100%) HK up
to 13.7m and mixed HK/country rock up
to 22.9m.
AD50/51/52 interpreted as one body
dipping 5-10 degrees with a true
thickness of 10m, over a 260m strike

Resource categories were completed in accordance 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 is
conceptual in nature, there has been insufficient information to define a mineral resource and it is
uncertain if further exploration will result in the target being delineated as a mineral resource.

54. Targeted Contracting for Small and Local Suppliers
Stornoway emphasises local hiring and procurement, with contracts
tailored for local businesses.
Stornoway prioritizes, wherever possible, hiring and contracting in the
Cree communities of Eeyou Itschee, particularly Mistissini, and with the
families of Sydney Swallow (Kiskinshiish Camp Services) and Emerson
Swallow (Swallow-Fournier), Tallymen for the Renard area.
In 2015 Stornoway purchased $95 million in goods and services from
Mistissini, Chibougamau and Chapais, and estimates $8 million in payroll
added to the local economy.

55. Communities
Stornoway is committed to fostering a positive relationship with its communities.
55
In addition to employment and business development
opportunities, Stornoway aims to foster educational and
training development in youth, respect for traditional
activities, two-way communication with community
representatives on project impacts, and support for local
charitable organisations.
Stornoway undertakes regular communication with our
employees at site, and communicates more formally
through community committees such as the Renard
Committee, the Environment Committee, the Training &
Employment Committee, and the Comité de Liaison Renard.
Our annual Sustainable Development Report is delivered to
each household in the region.
Stornoway’s commitments are laid out in our 2012
Mecheshoo Agreement with the Cree Nation of Mistissini
and the Grand Council of the Crees (EI), and our 2012
Declaration of Partnership with Chibougamau and Chapais.
