Stornoway Provides Renard Drilling Update: Renard 2 Kimberlite Greatly Expanded
Stornoway Diamond Corporation (TSX-SWY) is pleased to announce the completion of three deep delineation drill holes on the Renard 2 kimberlite pipe, located at the Foxtrot Property in North Central Qu?bec. The Foxtrot Property, 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 holes were drilled as part of an ongoing resource expansion and optimization program at Renard aimed at testing for the presence of additional mineral resources within the deeper and more poorly delineated portions of the Renard 2 and Renard 3 kimberlite pipes.
All three holes drilled to date have successfully extended the dimensions of the Renard 2 kimberlite pipe at depth, in comparison to the geological model used in the recent NI 43-101 compliant mineral resource statement (Stornoway Press Release dated December 15, 2008). One hole in particular, R2-55, has returned an intersection of kimberlite 176 meters longer than expected from previous geological modeling. The implied true horizontal width of this newly discovered zone of kimberlite almost triples the north-south dimension of the Renard 2 pipe to 150 meters at a depth of 500 meters below surface. Drill hole results from the three completed holes are as follows:

1 A negative ("-") difference indicates a decrease in geological model size. A positive (?+?) indicates an increase in model size. Differences between expected and actual contacts have a smaller influence on the shape of the geological model at the top of the pipe than at the bottom owing to the amount of geological control already existing.
2 Includes a 17 meter intersection of Country Rock Breccia with Kimberlite (?CRB+K?) between 117 and 134 meters.
3 Includes a 29 meter intersection of Country Rock Breccia with Kimberlite (?CRB+K?) between 331 and 360 meters.
Matt Manson, President and CEO commented: ?The thick new intersection of kimberlite returned by the R2-55 drill hole is an impressive result. It implies a substantial amount of new kimberlite in the lower section of the Renard 2 pipe, all within the scope of the existing underground mine design contained within the Renard Preliminary Assessment. We anticipate that the impact of this new discovery on the economics of the project will be positive and significant.?
R2-55 was designed to test the nature of the northern contact of the Renard 2 kimberlite within a 300 meter vertical section of the geological model (270 to 570 meters below surface) that was unconstrained by previous drilling (see illustration below). The discovery of some additional kimberlite was anticipated. However, the very long intersection, and the existing drill hole pattern in this area, are consistent with a greatly enlarged northern limb of the pipe that may extend from 570 meters up to 200 meters below surface, where kimberlite intersections not currently incorporated into the present geological model and mineral resource statement have been observed (the Renard 2 ?Bulge?). The new intersection also raises the possibility of substantial quantities of kimberlite below 570 meters depth.
Preliminary field logging indicates that the kimberlite intersected in this new area is comprised of Brown Transitional Kimberlite Breccia (?Kimb2b?), Hypabyssal Kimberlite Breccia (?HKB?) and Blue Tuffisitic Kimberlite Breccia (?Kimb2a?). The first two of these units are dominant and, as summarized in the recent NI 43-101 Report, are also the two most highly diamondiferous units within the Renard 2 kimberlite.

Given the potential size of the new discovery zone at Renard 2, additional delineation drilling in this area will be undertaken prior to the completion of the current winter program. Drilling of three deep delineation drill holes is also underway at the Renard 3 kimberlite pipe. It is expected that the results of the current winter drill program, together with drilling scheduled for the summer, will be incorporated into a revised NI 43-101 mineral resource statement for the project to be completed prior to the end of the year.
