Stornoway Diamond Corporation  (TSX-SWY) is pleased to provide a progress update  on feasibility level work at the Renard Diamond Project, Stornoway's flagship  project located in North Central Québec. 
  In July 2010, Stornoway announced  the commencement of a full program of mine design, environmental assessment,  permitting and community engagement designed to lead to a production decision at  Québec's first diamond mine. Since this time, Stornoway  has acquired a 100% interest in Renard through the acquisition of the 50%  interest previously owned by DIAQUEM Inc. (Stornoway press release dated April  1, 2011), increased the size of the Renard National Instrument 43-101 compliant  Mineral Resource (Stornoway press release dated January 24, 2011), and welcomed  the Québec Government announcement of final funding for the Route 167 Extension  road development project (Stornoway press release dated March 18, 2011). Work  on the project itself is well advanced, and is summarized as follows.
Schedule of Feasibility Study and Permitting
  The Renard Feasibility Study and its  accompanying Environmental and Social Impact Assessment ("ESIA") are on track  for completion in the third quarter of this year. A separate Feasibility Study  and Environmental Assessment for a power line to connect the project to the  James Bay hydro-electric network are also underway under the auspices of  Hydro-Québec. The Renard Diamond Project falls under the environmental  protection regimes of the James Bay and  Northern Québec Agreement (the "JBNQA") and the Canadian Environmental  Assessment Act. Subject to a schedule to be established by the Review Committee of the  JBNQA ("COMEX"), it is currently expected that community hearings will be held in the  fourth quarter of 2011 and, subject to the satisfaction of all regulatory  requirements, the project will be eligible for the receipt of Certificates of  Authorization by the end of the first quarter of 2012. Once the provincial and federal administrators  have issued authorizations for project development, final mine permits will be  sought from the Québec Ministère du  Développement durable, de l'Environnement et des Parcs, the Ministère des Ressources Naturelles et de la  Faune, and all relevant federal authorities. In  support of this schedule, an expenditure of $14.3m has been budgeted for the  completion of all project feasibility work programs, permitting and associated  pre-development activities to the end of March 2012, to be funded from existing  cash resources.
Mine Plan Development
  The Renard mine plan currently under  development within the Feasibility Study contemplates a combined open pit and  underground operation focused initially on the high grade Renard 2 and Renard 3  kimberlite pipes mined at a rate of 6,000 tonnes per day (2.1 million tonnes  per year). The potential for production expansion beyond 6,000 tonnes per day is  also being investigated through the addition of supplementary, open pittable  ore from the nearby Renard 65 kimberlite. To this end, Stornoway expects to  complete a 5,000 tonne bulk sample of Renard 65 so as to recover a large parcel  of diamonds for valuation purposes. This work will be undertaken in 2012, in  time to allow the conversion of Renard 65 from an Inferred to an Indicated  Mineral Resource and, if warranted, to a Mineral Reserve, prior to construction  start-up.
Diamond Valuation
  Prior to the finalization of the  Feasibility Study, Stornoway will conduct a full, open market diamond valuation  exercise in Antwerp, Belgium on the approximately 8,300 carats of diamonds  recovered from the Renard 2, Renard 3 and Renard 4 kimberlite pipes and the  Lynx and Hibou kimberlite dykes. These diamond parcels were last valued in  September 2009, at which time WWW  recommended a modeled "Base Case" diamond price estimate for both the  Renard 2 and Renard 3 valuation samples of US$117 per carat (estimated at a +1  DTC sieve size cut-off), with a "High" modeled price estimate of  US$131 per carat and a "Low" modeled price estimate of US$103 per  carat. Since this time, market prices for rough diamonds have increased  significantly. The revised modeled price estimate obtained from the new WWW  valuation exercise will be utilized in the financial model within the  Feasibility Study and for future mine planning.
Road Access and Development Schedule
  On March 17, 2011 it was announced  that the Québec Government will commit to the development of the Route 167  Extension under the auspices of the "Plan Nord", the strategic initiative to  develop the north of Québec.  The Route  167 Extension (also known as the "Route des Monts Otish") will provide year  round highway access to the Renard Diamond Project by way of the communities of  Mistissini and Chibougamau. Road construction is expected to commence this  year, and Stornoway anticipates first vehicle access to the Renard site for  construction mobilization by the first quarter of 2013 through the utilization  of an upgraded seasonal road and construction easements. The Renard Feasibility  Study will establish the optimum schedule for mine construction and production  start-up based on this road access time-line.
Stakeholder Relations
  Consultation  with communities, including public open houses and individual stakeholder  meetings, have been undertaken in conjunction with the ESIA and mine permitting  processes. With the collaboration of the Crees of the James Bay region, Stornoway  has established an Environmental Exchange Group designed to provide a forum for  the exchange of environmental and traditional knowledge in the area of the  proposed development. Stornoway also is currently in negotiations with the Cree  Nation of Mistissini and the Grand Council of the Crees (Eeyou Istchee) with the aim of concluding an Impact and Benefits  Agreement. This agreement is expected to provide mine related employment and  contracting opportunities, as well as foster environmental and social protection.  This negotiation process follows upon the successful execution of a Pre-Development  Agreement between the parties in July 2010, and the establishment of a project  business development office in the community of Mistissini in January of this  year.

About the Renard Diamond Project
  The Renard Diamond Project is  located approximately 250 km north of the Cree community of Mistissini and 350  km north of Chibougamau in the James Bay region of North-Central Québec. In May  2010, Stornoway filed a National Instrument 43-101 compliant technical report  for the Preliminary Assessment at Renard that estimated the project to have the  potential to produce approximately 30 million carats of diamonds over a 25 year  mine life, with a pre-tax Net Present Value of C$885 million (at an 8% discount  rate) and an Internal Rate of Return of 24.8%. National Instrument 43-101  compliant Indicated and Inferred Mineral Resources currently stand at 23.8 and  17.5 million carats respectively, with a further 23.5 to 48.5 million carats  classified as a non-resource, "potential mineral deposit". All kimberlites  remain open at depth. Total capital investment is currently estimated to be $511  million, with an average operating expenditure of approximately $67 million per  year and a workforce of 300 people. Readers are referred to the technical  report in respect of the Renard Diamond Project for further details and  assumptions relating to the project.

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; (vi) expected time frames for completion of  permitting and regulatory approvals, completion of a Feasibility Study and  making a production decision; (vii) future exploration plans; and (viii)  sources of and anticipated financing requirements.  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 and related Environmental and Social Impact Assessment; (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 a production decision will be made, and that  decision will be positive; (vii) anticipated timelines for the commencement of  mine production; (viii) anticipated timelines related to the Route 167  extension and the impact on the development schedule at Renard; (ix) anticipated  timelines for community consultations and the conclusion of an Impact and  Benefits Agreement; (x) market prices for rough diamonds and the potential  impact on the Renard Project's value; (xi) future exploration plans and  objectives. 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.
