STORNOWAY REPORTS UPDATED RENARD PRELIMINARY ASSESSMENT PRE-TAX NPV INCREASES BY 1,400% TO $C885 MILLION
Stornoway Diamond Corporation (TSX-SWY) is pleased to announce the receipt of an updated Preliminary Assessment for the Renard Diamond Project in North Central Qu?bec. The Renard Diamond Project, which includes the Renard kimberlite pipes and the Lynx-Hibou system of kimberlite dykes, is a 50:50 joint venture with SOQUEM INC. (?SOQUEM?). The study comprises a conceptual mine plan, capital and operating cost estimates, and cash flow model prepared by Scott Wilson Roscoe Postle Associates Inc. (?Scott Wilson RPA?), a diamond processing plant design, with capital and operating cost estimates, prepared by AMEC Americas Limited (?AMEC?), and social, environmental and permitting aspects contributed by Stantec Experts-conseil limit?e (?Stantec?). The conceptual mine plan is based upon a National Instrument (?NI?) 43-101 compliant mineral resource estimate prepared by Golder Associates Ltd. and reported previously by Stornoway on December 8th, 2009.
Highlights of the study, on a 100% project basis, are as follows:
- Base case estimates of pre-tax Net Present Value (?NPV?) and Internal Rate of Return (?IRR?) at C$885 million (at an 8% discount rate) and 24.8% respectively using a September 2009 diamond valuation of US$117/carat and a US dollar exchange rate of C$1.11.
- A conceptual mine life of 25 years based on a production rate of 1.8 million tonnes per year and a total diamond production of 30 million carats.
- Pre-production capital cost of C$450 million, including contingencies, which increases to a total capital cost of C$511 million after sustaining capital and closure cost.
- Average life of mine operating cost of C$39.45/tonne in a conceptual mine plan utilizing both open pit and underground mining.
- Estimates of pre-tax NPV and IRR at C$1,173 million (at an 8% discount rate) and 29.7% respectively using current market assumptions for rough diamond pricing and the current US dollar exchange rate.
President and CEO Matt Manson stated, "The updated preliminary assessment at Renard shows a dramatic increase in NPV compared to a year ago due to the recent threefold expansion in the project?s resource base. The larger mine that this resource can now support has also allowed us to reduce our estimate of overall operating costs at the expense of a modestly higher capital cost. Considerable effort has been applied to defining these costs with a high degree of confidence. As a consequence, we see Renard as a project with the potential to deliver a robust mining margin over a very long mine life.?
Executive Chairman Eira Thomas stated, ?This study has firmly established Renard as one of the best undeveloped diamond deposits in the world, well on track to becoming Qu?bec?s first diamond mine. We now have a project with size, mining margin and significant upside potential in the resource. Our principal kimberlite body, Renard 2, is high grade and open at depth, and limited exploration drilling has been undertaken on the other kimberlites below 300 m. As we move the project towards full feasibility this year, we intend to continue exploring what is proving to be a major diamond deposit.?
Stornoway will host a conference call to answer questions on the updated Renard Preliminary Assessment on Monday, March 22, 2010 at 11am Eastern Standard Time.

A playback will be made available after the call by dialing 1-800-408-3053 (local access 416-695-5800) with the access code 1081742.
Updated Preliminary Assessment
In December 2008 Stornoway reported the results from an initial NI 43-101 compliant Preliminary Assessment of the Renard Diamond Project (?Technical Report on the Preliminary Assessment of the Renard Project?, dated December 12, 2008, revised March 25, 2009), prepared by Agnico-Eagle Mines Limited (?Agnico?) and AMEC, and reviewed by Scott Wilson RPA. Since this time, a highly successful drill program has resulted in a tripling of both the indicated and inferred resources at Renard, prompting an update to the earlier study. For this updated 2010 Preliminary Assessment, Scott Wilson RPA have redesigned the conceptual mine plan to best exploit the new, larger resource, and refreshed the capital and operating cost estimates. AMEC have also supplied updated cost estimates for a diamond processing plant design derived from the earlier study, but now expanded to a rated capacity of 5,000 tonnes per day.
Cost estimation in the updated Preliminary Assessment has largely been completed to a Pre-Feasibility standard: most capital and operating costs are drawn from direct supplier quotes, or unit costs established at comparable Qu?bec and Nunavut mining operations, including those of Agnico. However, the conceptual nature of the mine design and the inclusion of inferred resources in the economic assessment define the study as a ?Preliminary Assessment? under NI 43-101 Standards of Disclosure for Mineral Projects. Inferred mineral resources are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and therefore there is no certainty that the Preliminary Assessment will be realized.
A base case financial model has been prepared using a US dollar exchange rate of C$1.11, as recommended for planning purposes by Scott Wilson RPA, and NPV has been calculated at an 8% discount rate. A diamond price estimate of US$117/carat has been adopted following a diamond valuation and modeling exercise undertaken by WWW International Diamond Consultants Ltd. ("WWW") in September 2009, and has been applied equally to the Renard 2, 3, 4 and 9 kimberlite pipes. An annual diamond price escalation factor of 2.5% has been applied starting in 2011, consistent with a consensus of recent diamond industry price forecasts. On this basis, pre-tax NPV is C$885 million, with a pre-tax IRR of 24.8% (Table 1).
