Stornoway Recovers High Value 9.78 Carat Stone From Renard 65 Bulk Sample


December 11, 2012: Montreal, Quebec – Stornoway Diamond Corporation (Stock Profile – TSX:SWY) announced that it is pleased to announce that during the ongoing processing of the Renard 65 bulk sample at Stornoway`s North Vancouver diamond recovery facility, a 9.78 carat diamond has been recovered that, with a preliminary valuation of $7,000 per carat, is one of the most valuable stones ever discovered at the Renard Diamond Project.

The 9.78 carat stone is an unbroken white octahedral gem. The next largest diamond in the sample is 6.41 carats in size and is also a white octahedral gem of high quality, with a preliminary valuation of $4,700 per carat. Approximately one third of the Renard 65 bulk sample’s heavy mineral concentrate has now been processed and a total of eleven diamonds larger than 1.8 carats in size have been extracted. Sample processing is continuing.

Matt Manson, Stornoway’s President and CEO, commented: “Our expectation for the Renard 65 bulk sample was that, as with the other Renard kimberlites, we would have recovered a number of high quality large stones given the size of the sample and its likely diamond size distribution. To have obtained two such large diamonds so early on, both of exceptional quality, is highly encouraging.”
The objective of the current sampling program at Renard 65 is the recovery of a parcel of diamonds large enough for valuation purposes, with a view to the conversion of material that is currently classified as an Inferred Mineral Resource to an Indicated Mineral Resource and then, if warranted, to a Mineral Reserve for inclusion in the project’s mine plan. The field portion of the bulk sample program was completed in November, and final diamond recovery results are expected in Q1 2013. Given the estimated diamond content at the sampling site, it is expected that approximately 1,000 carats of diamonds will be recovered, which will be sent to Antwerp, Belgium for valuation.

Within the larger Renard Mineral Resource inventory, Renard 65 contains an Inferred Mineral Resource of 3.7 Mcarats (representing 12.9 mtonnes at an average grade of 29 cpht) to a depth of 290m, with an exploration potential estimated at between 6.8 and 13.7 Mcarats (29.5 to 41.6 Mtonnes 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.
