Stornoway Provides Update on the Route 167 Extension

MONTREAL, QUEBEC -- (Marketwire) -- 10/29/12 -- Stornoway Diamond Corporation (TSX: SWY) is providing an update on construction progress on the Route 167 Extension, the road development project being undertaken by the Quebec Ministry of Transportation that will provide year round highway access to Stornoway's 100% owned Renard Diamond Project by way of the communities of Mistissini and Chibougamau.

Construction on the 243km long Route 167 Extension began in February of this year, and is being undertaken in four segments, "A" to "D" (http://stornowaydiamonds.com/_resources/news/20121029/figure1.jpg) . Construction on the southernmost segments A and B is progressing well, and to date 109km out of 143km has been completed to a standard sufficient for vehicle access. In the north, tree clearing and ground surveying are approaching completion over the 100km of the road covered by segments C and D. However, Stornoway has been advised by the Quebec Ministry of Finance that it intends to conduct a review of overall construction expenditures on the Route 167 Extension prior to the granting of contracts to complete the civil works on these northernmost segments. On the basis of the Ministry of Transportation's current plan for the construction of the Route 167 Extension, the delay in awarding contracts for civil works on segments C and D will result in a delay in the provision of all-season road access to the Renard Diamond Project, which was previously scheduled for July 2013.

On August 1st 2011, Stornoway announced the signing of two agreements with the Government of Quebec whereby Stornoway agreed to contribute $44 million to the construction of the Route 167 Extension and up to $1.215 million per year to its maintenance. Stornoway's financing obligations under these agreements are dependent, amongst other things, on the completion of the road on schedule. Stornoway, working closely with its community partners in the James Bay region, is in discussions with the Government of Quebec on alternate construction strategies for the Route 167 Extension by which the delay in the original access schedule for Renard might be mitigated, including the completion of road segments C and D on a modified scope. Stornoway will provide an update on the outcome of these discussions at the earliest possible time.

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 Quebec. In November 2011, Stornoway released the results of a Feasibility Study for Renard that highlighted the potential of the project to become a significant producer of high value rough diamonds over a long mine life. NI 43-101 compliant Probable Mineral Reserves stand at 18.0 million carats, with a further 17.5 million carats classified as Inferred Mineral Resources, and 23.5 to 48.5 million carats classified as non-resource exploration upside. All kimberlites remain open at depth. Pre-production capital cost stands at an estimated C$802 million, with a life of mine operating cost of C$54.71/tonne giving a 68% operating margin over an initial 11 year mine life. Readers are referred to the technical report dated December 29, 2011 in respect of the Renard Diamond Project for further details and assumptions relating to the project.

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.

Forward-looking statements are made based upon certain assumptions by Stornoway or its consultants and other important factors that, if untrue, could cause the actual results, performances or achievements of Stornoway to be materially different from future results, performances or achievements expressed or implied by such statements. Such statements and information are based on numerous assumptions regarding present and future business strategies and the environment in which Stornoway will operate in the future, including the price of diamonds, anticipated costs and ability to achieve goals. Certain important factors that could cause actual results, performances or achievements to differ materially from those in the forward-looking statements include, but are not limited to: (i) estimated approval date of the Environmental and Social Impact Assessment; (ii) required capital investment and estimated workforce requirements; (iii) estimates of net present value and internal rates of return; (iv) receipt of regulatory approvals on acceptable terms within commonly experienced time frames; (v) the assumption that a production decision will be made, and that decision will be positive; (vi) anticipated timelines for the commencement of mine production; (vii) anticipated timelines related to the Route 167 extension and the impact on the development schedule at Renard; (viii) anticipated timelines for community consultations and the impact of those consultations on the regulatory approval process; (ix) market prices for rough diamonds and the potential impact on the Renard Project's value; and (x) future exploration plans and objectives.

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 risk 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, (i) risks relating to variations in the grade, kimberlite lithologies and country rock content within the material identified as mineral resources from that predicted; (ii) variations in rates of recovery and breakage; (iii) the greater uncertainty of exploration targets; (iv) developments in world diamond markets; (v) slower increases in diamond valuations than assumed; (vi) risks relating to fluctuations in the Canadian dollar and other currencies relative to the US dollar; (vii) increases in the costs of proposed capital and operating expenditures; (viii) increases in financing costs or adverse changes to the terms of available financing if any; (ix) tax rates or royalties being greater than assumed; (x) results of exploration in areas of potential expansion of resources; (xi) changes in development or mining plans due to changes in other factors or exploration results of Stornoway; (xii) changes in project parameters as plans continue to be refined; (xiii) risks relating to receipt of regulatory approvals or the implementation of the existing Impact and Benefits Agreement with aboriginal communities; (xiv) the effects of competition in the markets in which Stornoway operates; (xv) operational and infrastructure risks; and (xvi) the additional risks described in Stornoway's most recently filed Annual Information Form, annual and interim MD&A, and Stornoway's anticipation of and success in managing the foregoing risks.
