Stornoway Reports Initial Diamond Results from Aviat 200 tonne
February 19th, 2009
BULK SAMPLE: 210 CPHT IN FIRST 43 TONNES
Stornoway Diamond Corporation (TSX-SWY) and Hunter Exploration Group (Hunter) are pleased to report results from the processing of the first 43 tonnes of an approximately 200 tonne sample of kimberlite collected during 2008 from within the Eastern Sheet Complex (“ESC”) of the Aviat Project, Nunavut. To date, 89.55 carats of diamonds have been recovered from 42.67 tonnes (dry weight) of kimberlite, representing an overall diamond recovery of 210 carats per hundred tonnes (cpht) for stones retained on a +1 DTC screen. The largest diamond recovered in this sample is a 0.81 carat grey fragment. The largest diamond recovered from the ESC from previous sampling is a 3.64 carat gem quality white dodecahedron (see press release dated January 21, 2008).This first 43 tonnes of sample was collected at a kimberlite outcrop within the ESC previously named “AV6”. The balance of the 200 tonne sample was collected at a nearby outcrop previously named “AV2”. The two outcrop samples are being processed separately, but “AV6” and “AV2” are now considered to represent two exposures of the same “ES1” kimberlite sheet occurring within the ESC. The second tranche of diamond recovery results are expected before the end of the first quarter.
Complete diamond recovery data, following Dense Media Separation (“DMS”) processing and utilizing both x-ray sorter and grease table recovery circuits, are as follows:
