STORNOWAY AND SHEAR RECOVER A 5.43 CARAT DIAMOND FROM CHURCHILL'S KAHUNA KIMBERLITE
Stornoway Diamond Corporation (SWY:TSX) and Shear Minerals Ltd. today announced the recovery of a 5.43 carat diamond from the second phase of processing of the 400-tonne bulk sample extracted earlier this year from the Kahuna kimberlite dyke on the Churchill Diamond Project, Nunavut. The diamond is a broken fragment of a larger stone which is estimated to have been up to 14 carats in size. This estimation is based on the presence of eight complementary broken diamonds recovered in the same sample. Results from the second phase of bulk sample processing at Kahuna are considered preliminary as diamond recovery is still underway.
“The discovery of these large diamond fragments proves the potential for the Kahuna kimberlite dyke to host larger diamonds,” says Shear President and CEO Pamela Strand. “We continue to be encouraged by the results of the Kahuna bulk sample. The presence of coarser diamonds will be an important driver of overall diamond value.”
Preliminary observation describes the five carat diamond as a white “clivage” stone that has broken on all sides along pre-existing fracture planes marked by inclusions. Other diamond fragments in the sample weigh 2.05, 1.54, 1.44, 1.33, and 1.11 carats. Work will be undertaken to attempt to reconstruct the diamond from fragments to determine the potential size of the original diamond as well as assess the potential breakage causes.
The current bulk sampling at Kahuna is aimed at establishing a preliminary grade and providing an initial assessment of diamond value. Processing of the remaining 270 tonnes of kimberlite from this year’s 400-tonne mini-bulk sample of Kahuna has been completed and final diamond recovery is currently underway with results expected within weeks.
Today’s diamond results are from the continuing processing of three surface samples collected by trenching along the strike length of the Kahuna kimberlite dyke in March and April of 2007. A sample grade of 0.88 carats per tonne (cpt) was disclosed in a press release on September 19, 2007. This grade is based on diamonds recovered on a 0.85mm sieve size or larger (using a square mesh) from a 106-tonne sample. The Kahuna kimberlite is a 2.8m to 4m wide vertical kimberlite dyke that trends for more than 5.5km based on geophysical interpretation. Other pending results from the 2007 field program include all microdiamond analyses from drilling and prospecting discoveries.
The Churchill Diamond Project is owned 41.86% by Stornoway and 58.14% by Shear, who is also the operator. The joint venture is comprised of the diamond rights to more than two million acres located near the communities of Rankin Inlet and Chesterfield Inlet in the Kivalliq region of Nunavut. Work is presently focused on continued exploration of new promising indicator mineral trains and geophysical anomalies as well as the evaluation of four significantly diamond-bearing, vertically-emplaced kimberlite dykes (up to 4m in width) that have returned sample grades of up to 2.18 carats per tonne. The 2007 field program is under the supervision of Jennifer Burgess, P. Geol., a Qualified Person under NI 43-101.
