MONTREAL, QUEBEC -- (Marketwire) -- 02/25/13 -- Stornoway Diamond Corporation (TSX: SWY) is pleased to report that it has completed diamond recovery from the Renard 65 bulk sample recently collected at Stornoway's 100% owned Renard Diamond Project located in north-central Quebec. In total, 962.8 carats of diamonds larger than a +1 DTC size sieve were recovered from 5080.8 dry tonnes. The size of the diamond sample recovered and the incidene of large diamonds are consistent with Stornoway's expectations for the Renard 65 kimberlite at this sample location.

The objective of the Renard 65 bulk sample was the collection of approximately 1,000 carats of Renard 65 diamonds for valuation purposes. Having achieved this objective, a diamond valuation exercise has been scheduled to take place shortly in Antwerp, Belgium.

As previously announced (Stornoway press release dated December 11th 2012) the largest diamond recovered from the sample was a 9.78 carat white octahedral gem with a preliminary valuation of $7,000 per carat. The next largest diamond was a 6.41 carat white gem also of high quality, with a preliminary valuation of $4,700 per carat.

The Renard 65 bulk sampling is being undertaken with a view to the potential conversion of material that is currently classified as an Inferred Mineral Resource to an Indicated Mineral Resource and, if warranted, to a Mineral Reserve for inclusion in the project's mine plan. Within the larger Renard Mineral Resource inventory, Renard 65 contains an Inferred Mineral Resource of 3.7 million carats (representing 12.9 million tonnes at an average grade of 29 carats per hundred tonnes) to a depth of 290m, with an exploration potential estimated at between 6.8 and 13.7 million carats (29.5 to 41.6 million tonnes at between 23 and 33 cpht) from 290m to 775m in depth. 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 exploration target is conceptual in nature, and it is uncertain if further exploration will result in it being delineated as a mineral resource.

The current bulk sample was extracted from a site that is known to represent a lower grade portion of the kimberlite, but which is easily accessible from surface. In 2008, a 266 tonne trench sample from the same location returned 51.8 carats for a diamond recovery of 19 cpht, identical to the current result.

Large Diamonds in Exploration Samples at Renard

A feature of the Renard Diamond Project has been the incidence of large, high value stones that have been recovered at each stage of exploration sampling since the project's discovery in 2001. The current Renard 65 bulk sample has continued this trend. In 2003 a white octahedral gem of at least 4 carats was discovered embedded in drill core at Renard 65. During the Renard bulk sampling program of 2007 a 15.46 carat top light brown "makeable" gem was recovered from Renard 2, a 10.15 carat white octahedral gem was recovered from Renard 3, and a broken 21.53 carat brown octahedral gem was recovered from the Lynx Dyke in three pieces of 11.73, 5.96 and 3.94 carats. In all, at least seven large stones have now been recovered from Renard with values in excess of US$4,000 per carat.
