This document contains forward-looking information (as defined in National Instrument 51 102 – Continuous Disclosure Obligations) and forward-looking statements within the meaning of Canadian securities legislation and theUnited States Private Securities Litigation Reform Act of 1995 (collectively referred to herein as “forward-looking information” or “forward-looking statements”). These forward-looking statements are made as of the date of thisdocument 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 relate to future events or future performance and include, among others, statements with respect to Stornoway’s objectives for the ensuing year, our medium and long-term goals, andstrategies to achieve those objectives and goals, as well as statements with respect to our management’s beliefs, plans, objectives, expectations, estimates, intentions and future outlook and anticipated events or results. Althoughmanagement considers these assumptions to be reasonable based on information currently available to it, they may prove to be incorrect.

Forward-looking statements 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 explorationtargets; (ii) the estimated amount of future production over any period; (iii) net present value and internal rates of return of the mining operation; (iv) expectations and targets relating to recovered grade, size distribution andquality of diamonds, average ore recovery, carats recovered, carats sold, internal dilution, mining dilution and other mining parameters set out in the 2016 Technical Report as well as levels of diamond breakage; (v) expectations,targets and forecasts relating to gross revenues, operating cash flows and other revenue metrics set out in the 2016 Technical Report, growth in diamond sales, cost of goods sold, cash cost of production, gross margins estimates,planned and projected diamond sales, mix of diamonds sold, and capital expenditures, liquidity and working capital requirements; (vi) mine and resource expansion potential, expected mine life, and estimated incremental orerecovery, revenue and other mining parameters from potential additional mine life extension; (vii) expected time frames for completion of permitting and regulatory approvals related to ongoing construction activities at theRenard Diamond Mine; (viii) the expected time frames for the completion of the open pit and underground mine at the Renard Diamond Mine; (ix) the expected financial obligations or costs incurred by Stornoway in connectionwith the ongoing development of the Renard Diamond Mine; (x) mining, development, production, processing and exploration rates, progress and plans, as compared to schedule and budget, and planned optimization, expansionopportunities, timing thereof and anticipated benefits therefrom; (xi) future exploration plans and potential upside from targets identified for further exploration; (xii) expectations concerning outlook and trends in the diamondindustry, rough diamond production, rough diamond market demand and supply, and future market prices for rough diamonds and the potential impact of the foregoing on various Renard financial metrics and diamondproduction; (xiii) the economic benefits of using liquefied natural gas rather than diesel for power generation; (xiv) requirements for and sources of, and access to, financing and uses of funds; (xv) the ability to meet SubjectDiamonds Interest delivery obligations under the Purchase and Sale Agreement; (xvi) the foreign exchange rate between the US dollar and the Canadian dollar; and (xvii) the anticipated benefits from recently approved plantmodification measures and the anticipated timeframe and expected capital cost thereof. 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” orvariations 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 ofhistorical 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 bematerially 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 businessprospects 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 diamondbreakage, the price of diamonds, anticipated costs and Stornoway’s ability to achieve its goals, anticipated financial performance, regulatory developments, development plans, exploration, development and mining activities andcommitments, access to financing, and the foreign exchange rate between the US and Canadian dollars. Although management considers its assumptions on such matters to be reasonable based on information currently availableto 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) the accuracy of our estimates regarding capital andestimated workforce requirements; (ii) estimates of net present value and internal rates of return; (iii) recovered grade, size distribution and quality of diamonds, average ore recovery, carats recovered, carats sold, internaldilution, mining dilution and other mining parameters set out in the 2016 Technical Report as well as levels of diamond breakage; (iv) the expected mix of diamonds sold, and successful mitigation of ongoing issues of diamondbreakage in the Renard Diamond Mine process plant and realization of the anticipated benefits from plant modification measures within the anticipated timeframe and expected capital cost; (v) the stabilization of the Indiancurrency market and full recovery of prices; (vi) receipt of regulatory approvals on acceptable terms within commonly experienced time frames and absence of adverse regulatory developments; (vii) anticipated timelines for the

By their very nature, forward-looking statements involve inherent risks and uncertainties. We caution readers not to place undue reliance on these forward- looking statements as a number of important risk factors could cause theactual outcomes to differ materially from the beliefs, plans, objectives, expectations, anticipations, estimates, assumptions and intentions expressed in such forward-looking statements. The operating results and financial conditionof the Corporation are subject to a number of inherent risks and uncertainties associated with its business activities, which include the financing, exploration, development, construction and operation of its mine and processingfacility. The operating results and financial condition are also subject to numerous external factors, which include economic, regulatory, legal, tax and market risks impacting, among other things, supply of materials and demand forrough diamonds, rough diamond prices, foreign exchange rates, inflation and the availability and cost of capital to fund the capital requirements of the business. Each of these risks could have a material adverse effect on theCorporation’s future business, financial condition, prospects, results of operations or cash flow, and could cause actual results to differ materially from those described in any forward-looking statements contained in thisdocument. There can be no assurance that the Corporation has been or will be successful in identifying all risks or that any risk-mitigating strategies adopted to reduce or eliminate risk will be successful. These risks should beconsidered when evaluating the Corporation and its guidance. With the exception of the going concern risk, which is described in the Corporation’s most recently filed MD&A, a comprehensive discussion of the risks faced by theCorporation can be found in the Corporation’s 2017 Annual MD&A and most recently filed AIF, which are available on SEDAR at www.sedar.com under the Corporation’s profile.

IFRS 15 – Adoption Impacts

IFRS 15, which was adopted effective January 1, 2018, supersedes IAS 11, Construction Contracts, IAS 18, Revenue and related Interpretations (“legacystandards”). It was applied using the modified retrospective method without adjustment of the comparative information. Revenues recognized fromthe Stream were impacted by the transition, whereas it was determined that the advance consideration received for future diamond deliveriescontained a significant financing component. As a result, both revenues and financial expenses have increased.

Diamond Sales

12

Renard Diamond Price Movements, Real Terms1

1. Sale by sale basis, normalized for variations in quality and size distribution2. Before stream and royalty3. Inclusive of supplemental diamonds (-7dtc) recovered in excess of the resource grade models (renamed from incidentals to supplementals in 2019)

Stornoway completed 9 tender sales in 2018, achieving a pricing of US$105 per carat (exclusive of supplemental diamond production)

Tender attendance in 2018 was strong: average of 174 attendees per sale (up from 142 attendees average for 2017).

Average of 117 of attendees bidding and 16 bids per lot on average (up from 13 bids per lot in 2017); reflecting competitive demand for Renard’s production.

First 5 sales of 2018 saw a strong mix of R2, R3 and R65 diamonds and good market conditions, resulting in achieved price of $111 per carat (exclusive of supplementals) and a real term pricing increase of 7%.

Last 4 sales of 2018 saw a weaker product quality from a production mix of mostly from lower grade R2 underground, and weaker market conditions for smaller and lower quality goods, resulting in US$97 per carats achieved, and real term pricing decrease of 6%.

2019 sales results will be reported inclusive of supplemental diamond production.

2019: Stable Production from Renard 2, Reintroduction of Renard 3 Ore in FeedR2 UG to be principal source of production ore looking forward.

First production blast December 2017; production ramp-up completed August 2018.

Ramp access; 6,000 tpd ore design capacity; surpassed this target in each month of Q4 2018.

First Experiences

More competent country rock and less competent kimberlite than expected.

Migration to assisted block caving as principal mining method; long term benefits in production costs and dilution.

First production panels developed at the north pipe margin of the 290m level in highly diluted, low grade kimberlite.

Grade has significantly increased as mining has progressed to the center of R2; recovered grade of 80 cpht in Q4 2018.

Favorable Global Rough Diamond Production Outlook1

Source: Bain & Company “The Global Diamond Industry 2017: The Enduring Story in a Changing World”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 increases2.
