Stornoway Provides Renard Project Update

Feasibility Study on Track for Delivery in Third Quarter

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 28, 2011) -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.
