Stornoway Provides Construction Update on the Renard Mine Road
All-Season Road Construction Initiated Ahead of Schedule

MONTREAL, QUEBEC -- (Marketwire) -- 03/27/13 -- Stornoway Diamond Corporation (TSX: SWY) is pleased to provide an update on progress made in the construction of the Renard Mine Road that will provide year-round vehicle access to the Renard Diamond Project by way of the communities of Mistissini and Chibougamau. Due to favourable weather conditions, construction of the Renard Mine Road has commenced earlier than anticipated, with overall progress already standing at 12% of expected work. First all-season vehicle access to Renard is currently scheduled for the fourth quarter of this year, as previously anticipated.

Under the terms of an agreement executed on November 15th, 2012 by Stornoway, the Quebec Ministere des Transports ("MTQ"), the Ministere des Ressources Naturelles, and the Ministere des Finances et de l'Economie ("MFE"), a 240km long all-season road linking Renard to the Quebec highway network is currently being constructed in four segments, A to D. Progress is well established on segments A and B, which are being completed by the MTQ as a 70km/hr two-lane gravel highway. Stornoway will complete the remaining 97km covered by segments C and D as a 50km/hr single lane mining road under the terms of a Financing Agreement executed on December 6th, 2012 between Stornoway and the MFE.

As previously reported, first vehicle access to the Renard project site was achieved on February 15th by way of a winter road constructed by the MTQ. The winter road, which opened early and remains in use currently, has been used to ship construction equipment and fuel to the project site and has allowed construction of the all-season Renard Mine Road to commence well ahead of the planned schedule. Consequently, Stornoway can report the following construction milestones achieved:


--  Construction camps for the accommodation of 100 people have been
    completed;
--  Building materials for 9 of 16 permanent bridges have been delivered to
    watercourse sites and the abutments of 3 bridges have been completed;
    and
--  Dry-fill foundations have been completed and culverts delivered on 85%
    of all wetland sites;

Several road construction contracts have been entered into by Stornoway with businesses located in the James Bay Region of Quebec or associated with the Crees of Eeyou Itschee. These include:


--  A consortium of the Eskan Company, the Development Corporation of the
    Cree Nation of Mistissini, and Swallow-Fournier inc., for road
    construction;
--  Nordic Structures Bois, a wholly-owned subsidiary of Chantiers
    Chibougamau Ltee, for bridge construction;
--  Jos Ste-Croix & Fils Ltee of Chibougamau for construction management;
--  The Eenatuk Forestry Corporation for tree clearing; and
--  The Kiskinchiish Corporation for camp services and catering;
--  Petronor, a wholly owned Cree enterprise, for fuel supply.

On December 17th, 2012, Stornoway announced that it had received the transfer of the Certificate of Authorization for the construction of the Renard Mine Road from the Quebec Ministere du Developpement durable, de l'Environnement, de la Faune et des Parcs ("MDDEFP"). Consistent with this transfer, and the reduced scope of the Renard Mine Road compared to the two-lane public highway that was previously contemplated, Stornoway filed an amendment to the road project's Environmental and Social Impact Assessment on February 15th, 2013 with the Evaluation Committee ("COMEX") of the James Bay and Northern Quebec Agreement, the environmental protection regime for the James Bay Region of Quebec.

About the Renard Mine Road

Construction of the road that will provide all-season vehicle access to the Renard Project began in February 2012 as the "Route 167 Extension". Under the terms of the November 2012 Framework Agreement between Stornoway and the Government of Quebec, Quebec will complete the first 143km of road as a 70km/hr two-lane gravel highway and Stornoway will undertake the construction of a 50km/hr single lane mining road over the remaining 97km as the "Renard Mine Road". The cost of the Renard Mine Road is estimated at $77 million, including a 15% contingency. Under the terms of the December 2012 Financing Agreement between Stornoway and Quebec, this cost will be funded through a credit facility provided to Stornoway bearing interest at the rate of 3.35% and amortized over a period of 15 years. In order to provide additional contingency, Stornoway will be entitled to draw an additional $7.7 million bearing interest at the rate of 6.3%, for a total facility of up to $84.7 million . The schedule of repayment of these loans will be based on the financing and construction schedule of the Renard Diamond Project. To-date, Stornoway has drawn $26.2 million from the credit facility.

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 at Renard, followed by an Optimization Study in January 2013, which highlighted the potential of the project to become a significant producer of high value rough diamonds over a long mine life. Probable Mineral Reserves as defined under National Instrument ("NI") 43-101 stand at 17.9 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$752 million, with a life of mine operating cost of C$57.63/tonne giving a 67% operating margin over an initial 11 year mine life. Readers are referred to the technical report dated December 29th, 2011 in respect of the November 2011 Feasibility Study for the Renard Diamond Project, and the press release dated January 28, 2013 in respect of the January 2013 Optimization Study, for further details and assumptions relating to the project.

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 Stornoway's ability to achieve its goals.
