Stornoway Announces Positive Microdiamond Results From Renard 1
February 23, 2011
Potential for Additional Resources Following Discovery of Diamond Characteristics Similar to Renard 65
Stornoway Diamond Corporation (TSX-SWY) is pleased to announce positive microdiamond results from Renard 1, the second largest kimberlite at the Renard Diamond Project, located in North Central Quebec. 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 DIAQUEM INC. ("DIAQUEM"), a wholly-owned subsidiary of SOQUEM INC. ("SOQUEM"), itself a wholly-owned subsidiary of Société générale de financement du Québec ("SGF"), the Québec government's main industrial and financial holding company. On February 10, 2011, Stornoway announced that an agreement to acquire DIAQUEM'S 50% interest in the Renard Diamond Project had been approved by shareholders and is expected to close on April 01, 2011, on which date Stornoway will have acquired 100% ownership of the project. A bankable feasibility study is on schedule for completion in the 3rd quarter of 2011.
Renard 1 was discovered in 2001 and was subsequently drill tested with a total of 11 diamond drill holes representing 1,974 meters (see map of Renard Kimberlite locations). Initial diamond recoveries were low and, at present, Renard 1 does not form part of the project's National Instrument ("NI") 43-101 compliant Mineral Resource (see press release of January 24, 2011). Starting in 2009, Stornoway undertook a review of the pre-existing sampling and geological data at Renard 1, and concluded that the diamond potential of the body had likely been underestimated. In 2010 a single, additional drill hole of 537 meters length was completed, and drill core intersections were sampled to determine microdiamond content by caustic fusion analysis. The results of this work are summarized in the table below.
|NUMBER OF DIAMONDS PER SIEVE SIZE (MM SQUARE MESH SIEVE)|
|Sample||Sample weight (kg)||0.106 to 0.150mm||0.150 to 0.212mm||0.212 to 0.300mm||0.300 to 0.425mm||0.425 to 0.600mm||0.600 to 0.850mm||Total|
These micro-diamond results confirm that Renard 1 has strong similarities to the nearby Renard 65 kimberlite, with an almost identical diamond content and coarse diamond size frequency distribution. A location map, and a comparative stone count plot demonstrating the similarities in the micro-diamond signatures of the two kimberlites (taking full account of sample geology and dilution) can be found on the Stornoway website at
Matt Manson, President and CEO commented: "With Renard 1, we undertook to re-assess the economic potential of a large body that lay very close to our existing mineral resources and which we felt had been overlooked. The new microdiamond results have rewarded this approach. The developing Renard mine plan contemplates a combined open pit and underground operation established, initially, on the high grade Renard 2 and 3 kimberlites. However, Renard 65 has the potential to form a large, supplemental resource that is lower grade but easily open-pittable. Today's news now gives strong encouragement that Renard 1 has a similar potential. Ten years following its initial discovery, the Renard Project continues to demonstrate its considerable resource upside."
On the basis of drilling completed to date, Stornoway estimates Renard 1 to contain 9.1 million tonnes of kimberlite to a depth of 282 meters. Renard 65 occurs 300m north of Renard 1 and is the largest kimberlite at the project. The current NI 43-101 compliant mineral resource for Renard 65 is 12.9 million tonnes of Inferred Resource to 290 meters depth at an average grade of 29 carats per hundred tonnes ("cpht"). An additional 29.5 to 41.6 million tonnes of non-resource, potential mineral deposit has been estimated at between 23 to 33 cpht. Both kimberlites are composed of several pipe-filling volcaniclastic to coherent kimberlite units and a distinct hypabyssal kimberlite unit. The reader is cautioned that mineral resources that are not mineral reserves do not have demonstrated economic viability. In addition, 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.
Stornoway is currently formulating a 2011 program of resource assessment at Renard that is expected to include the collection and processing of a large tonnage bulk sample from Renard 65. The purpose of this sample is to collect a large enough parcel of diamonds for valuation so as to allow the conversion of the existing Inferred Mineral Resource to an Indicated Mineral Resource. Should the results of this work confirm the potential viability of open pit mining at Renard 65, it is expected that additional drilling and sampling programs at Renard 1 will be initiated with a view to expanding the quantity of open-pittable resources of this type. In the meantime, petrographic, density and geochemical studies, as well as other work on Renard 1, remain outstanding. This data will be used to update the preliminary geological model and to better quantify a potential mineral deposit estimate for the body.

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%. Total capital investment was estimated at C$511 million. 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. Pending the completion of all ongoing mine feasibility and environmental and social impact assessments, and the receipt of all regulatory approvals, Stornoway currently anticipates being able to make a potential production decision at Renard by the end of 2011. Readers are referred to the technical report 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
All forward-looking statements are based on Stornoway's or its consultants' current beliefs as well as various assumptions made by and information currently available to them. Many of these assumptions are set forth in the news release and include: (i) estimates of net present value and internal rates of return; (ii) estimates of potential production and duration of mine life; (iii) estimated completion date for the Feasibility Study; (iv) required capital investment and estimated workforce requirements; (v) receipt of regulatory approvals on acceptable terms within commonly experienced time frames; (vi) the assumption that the partners will make a production decision, and that decision will be positive; (vii) anticipated timelines for the commencement of mine production. Although management considers these assumptions to be reasonable based on information currently available to it, they may prove to be incorrect. Many forward-looking statements are made assuming the correctness of other forward looking statements, such as statements of net present value and internal rate of return, which are based on most of the other forward-looking statements and assumptions herein. The cost information is also prepared using current values, but the time for incurring the costs will be in the future and it is assumed costs will remain stable over the relevant period.
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 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, risks relating to variations in the grade, kimberlite lithologies and country rock content within the material identified as mineral resources from that predicted, variations in rates of recovery and breakage; the greater uncertainty of potential mineral deposits, developments in world diamond markets, slower increases in diamond valuations than assumed, risks relating to fluctuations in the Canadian dollar and other currencies relative to the US dollar, increases in the costs of proposed capital and operating expenditures, increases in financing costs or adverse changes to the terms of available financing, if any, tax rates or royalties being greater than assumed, results of exploration in areas of potential expansion of resources, changes in development or mining plans due to changes in other factors or exploration results of Stornoway or its joint venture partners, changes in project parameters as plans continue to be refined, risks relating to receipt of regulatory approvals or settlement of an Impact and Benefits Agreement, the effects of competition in the markets in which Stornoway operates, operational and infrastructure risks and the additional risks described in Stornoway's most recently filed Annual Information Form, annual and interim MD&As, and Stornoway's anticipation of and success in managing the foregoing risks. Stornoway cautions that the foregoing list of factors that may affect future results is not exhaustive.
