Stornoway Reports Filing of NI 43-101 Technical Report for Renard Preliminary Assessment

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 15, 2008) - Stornoway Diamond Corporation (TSX:SWY) is pleased to announce the filing on SEDAR on December 12, 2008 of a National Instrument ("NI") 43-101 technical report on the Renard Project located at the Foxtrot Property in North Central Quebec. The Foxtrot Property is a 50:50 joint venture with SOQUEM INC. ("SOQUEM"). The independent technical report has been prepared by Scott Wilson Roscoe Postle Associates Inc. (Scott Wilson RPA) and is the qualifying report relating to the Renard Preliminary Assessment. AMEC Americas Limited (AMEC) and SENES Consultants Limited (SENES) have prepared or contributed to sections of this technical report. The technical report includes improved estimates of project economics resulting from certain conceptual mine plan efficiencies identified since the initial results of the preliminary assessment were disclosed by Stornoway on October 28th, 2008, available at http://media3.marketwire.com/r/October28th2008. The improved economics are highlighted as follows:

Highlights

- Pre-tax IRR on a "Base Case" economic assessment utilizing a 5.9 million carat mineral resource from Renard kimberlites 2, 3 and 4 has increased marginally to 14.2% (12.1% after tax) from 13.9% (11.8% after tax). Pre-Tax NPV (calculated before tax at an 8% discount rate) increases to C$56m from C$52m.

- Pre-tax IRR on an "R4-R9 Price Sensitivity" economic assessment has increased to 17.5% (14.9% after tax) from 16.4% (13.9% after tax), with pre-tax NPV increasing to C$93m from C$78m. This upside economic assessment utilizes an expanded 6.2 million carat mineral resource from Renard kimberlites 2, 3, 4 and 9 and is predicated upon the application of an alternate diamond price to both of the Renard 4 and Renard 9 kimberlites.

The Renard Preliminary Assessment comprises a National Instrument ("NI") 43-101 compliant mineral resource estimate and a diamond processing plant design prepared by AMEC Americas Limited ("AMEC"). A conceptual mine plan, capital and operating cost estimate, and an economic assessment were prepared by Agnico-Eagle Mines Limited ("Agnico") and reviewed and accepted by Scott Wilson RPA. The economic assessment is based, in part, on Inferred Mineral Resources, and is preliminary in nature. Inferred Mineral Resources are considered too geologically speculative to have mining and economic considerations applied to them that would enable them to be categorized as Mineral Reserves. There is no certainty that the Preliminary Assessment will be realized.

Since the results of the Preliminary Assessment were initially reported on October 28th, 2008, available at http://media3.marketwire.com/r/October28th2008, no changes have been made to the mineral resource statement or estimate of potential mineral deposits. However, additional inferred mineral resource from the Renard 2 kimberlite has been added to the conceptual mine plan resulting in a marginally increased IRR under the base case economic assessment. In addition, an additional 540,000 tonnes of inferred mineral resource in the Renard 9 kimberlite has been added to the conceptual mine plan in the economic assessment scenario that applies the Renard 2 and 3 diamond price to the Renard 4 and Renard 9 kimberlites. This additional Renard 9 mineral resource has had a more significant impact on the project economics under this upside scenario. Estimates of project capital cost, operating cost and mining method remain the same, as does the mineral resource statement and the assumptions used in the financial model.

Overview of the Mineral Resource Statement, Estimate of Potential Mineral Deposit, and Conceptual Mine Plan.

The NI 43-101 compliant mineral resource at Renard comprises 7.0 million carats of Indicated Resources (11.6 million tonnes at an average grade of 60 carats per hundred tonnes, or "cpht") and 4.5 million carats of Inferred Resources (7.2 million tonnes at an average grade of 63 cpht). Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. Extensive upside has been identified in the form of an additional 9 to 21 million carats classified as potential mineral deposit (14 to 32 million tonnes ranging from 31 to 164 carats per hundred tonnes). The potential quantity and grade of any potential mineral deposit is conceptual in nature, and it is uncertain if further exploration will result in the target being delineated as a mineral resource. Consequently, the economic assessment, in both "Base Case" and "R4-R9 Price Sensitivity" scenarios, does not incorporate any of this non-resource, conceptual material. The evaluation of the large quantity of potential mineral deposit at Renard will be the prime focus of the joint venture in the coming year. If confirmed as additional mineral resource, it offers the potential to significantly extend the preliminary mine life and enhance the project's economics prior to a formal production decision.

The conceptual mine plan combines open pit mining and sublevel, open stope underground mining. The mining sequence and design were determined by optimizing the pit depth and underground stopes to achieve a production rate of 3,500 tonnes/day or 1.3 million tonnes per annum. The capital expense is estimated to be $308 million, including $73 million for a diamond processing plant and including a contingency of $50 million. Operating costs (op-ex) are anticipated to average C$50.35/tonne, including $14.06/tonne for open pit mining, $22.74/tonne for underground mining, C$14.92/tonne for processing and C$16.13/tonne for surface services and general administration. Capital and operating costs were estimated between April and July 2008 through contractor quotes or real-case unit costs derived from current Agnico operations. Site access is based on the assumed availability of an all-season road from the south.

Financial models have been prepared using a US dollar 3-year historical exchange rate of C$1.146 and assuming a 3% diamond marketing cost. Diamond prices are as of an open market valuation exercise undertaken by WWW International Diamond Consultants Ltd. ("WWW") in March 2008 (Stornoway press release dated April 28th 2008, available at http://media3.marketwire.com/r/April28th2008) and an annual diamond price escalation factor of 2.5% has been applied. The diamond price escalation factor does not commence until 2011, and extends through the life of mine, consistent with a consensus of recent diamond industry price forecasts.

The two adjusted economic assessment scenarios are summarized as follows:
