Stornoway Announces Award of Environmental and Social Impact Assessment Contract for the Renard Diamond Project

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 22, 2010) - Stornoway Diamond Corporation (TSX:SWY) is pleased to announce that Roche ltd. Groupe-conseil ("Roche") has been awarded the contract for the preparation of the Renard Diamond Project Environmental and Social Impact Assessment ("ESIA"). Roche ltée is an international engineering-construction and environmental consultant firm headquartered in Québec City. The Roche contract will cover the Renard Project Impact Assessment and its Closure and Rehabilitation Plan, with EnviroCree ltd. to be retained as a sub-consultant to provide local expertise. The Renard Diamond Project is a 50:50 joint venture with DIAQUEM INC., a wholly-owned subsidiary of SOQUEM INC., itself a wholly-owned subsidiary of Société générale de financement du Québec ("SGF"), the Québec government's main industrial and financial holding company.

Matt Manson, President and CEO, commented: "The award of this ESIA contract is an important milestone for the Renard Project. The Roche-EnviroCree team is highly experienced in all environmental and social aspects of mine development in the James Bay region of Quebec, and this study will comprise an important component of the project's overall permitting process."

In March 2010, Stornoway released the results of an updated Preliminary Assessment at Renard which outlined a base case estimate of pre-tax Net Present Value of C$885 million (at an 8% discount rate) and an Internal Rate of Return of 24.8%. This study showed the project to have the potential to produce approximately 30 million carats of diamonds over a 25-year mine life based on the currently defined National Instrument ("NI") 43-101 Indicated and Inferred Resources. The Environmental and Social Impact Assessment is expected to be substantially completed by the third quarter of 2011.

This document 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 document 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 potential mineral deposits; (ii) the amount of future production over any period; (iii) net present value and internal rates of return of the proposed mining operation; (iv) capital costs and operating costs; (v) mine expansion potential and expected mine life; and (vi) expected time frames for completion of permitting and regulatory approvals, completion of a Feasibility Study and making a production decision. 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.

All forward-looking statements are based on Stornoway's or its consultants' current beliefs as well as various assumptions made by and information currently available to them. Many of these assumptions are set forth in the news release and include: (i) estimates of net present value and internal rates of return; (ii) estimates of potential production and duration of mine life; (iii) estimated completion date for the Feasibility Study; (iv) required capital investment and estimated workforce requirements; (v) receipt of regulatory approvals on acceptable terms within commonly experienced time frames; (vi) the assumption that the partners will make a production decision, and that decision will be positive; (vii) anticipated timelines for the commencement of mine production. Although management considers these assumptions to be reasonable based on information currently available to it, they may prove to be incorrect. Many forward-looking statements are made assuming the correctness of other forward looking statements, such as statements of net present value and internal rate of return, which are based on most of the other forward-looking statements and assumptions herein. The cost information is also prepared using current values, but the time for incurring the costs will be in the future and it is assumed costs will remain stable over the relevant period.

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 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, risks relating to variations in the grade, kimberlite lithologies and country rock content within the material identified as mineral resources from that predicted, variations in rates of recovery and breakage; the greater uncertainty of potential mineral deposits, developments in world diamond markets, slower increases in diamond valuations than assumed, risks relating to fluctuations in the Canadian dollar and other currencies relative to the US dollar, increases in the costs of proposed capital and operating expenditures, increases in financing costs or adverse changes to the terms of available financing, if any, tax rates or royalties being greater than assumed, results of exploration in areas of potential expansion of resources, changes in development or mining plans due to changes in other factors or exploration results of Stornoway or its joint venture partners, changes in project parameters as plans continue to be refined, risks relating to receipt of regulatory approvals or settlement of an Impact and Benefits Agreement, the effects of competition in the markets in which Stornoway operates, operational and infrastructure risks and the additional risks described in Stornoway's most recently filed Annual Information Form, annual and interim MD&As, 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. 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.
