SASKATOON, SK, Nov. 2 /CNW/ - George H. Read, P. Geo., Senior Vice President Exploration, is pleased to announce the ninth set of diamond recoveries from the Star Kimberlite. The diamond recoveries to date total 2,120.68 carats from 16,206.88 dry tonnes processed. These results are for seven kimberlite batches of a total of some 80 to 100 kimberlite batches that will be processed as part of the bulk sampling program on the Star Diamond Project, the aim of which is to recover a parcel of some 3,000 carats for valuation purposes. A total of 2,162 commercial sized diamonds (greater than 1.18 millimetre square mesh screen), collectively weighing 304.52 carats, has been recovered from the treatment of 1,630.94 dry tonnes of kimberlite. Forty-two diamonds greater than one carat have been recovered and the four largest stones are: 19.68, 11.57, 8.07 and 5.31 carats, respectively. In addition, 292 diamonds (4.43 carats) were recovered down to 0.85 millimetre square mesh. The colour of 73 percent of these diamonds has been classified as white, with a further 11 percent classified as off-white.
These seven kimberlite batches (of a total of 50 processed) have been mined from the Southeast drive (Batches 35A, 35B, 36, 37, 38A and 38B) and the North drive (Batch 40) developed from the 235 metre shaft station. All of these kimberlite batches have been recovered from within the Early Joli Fou equivalent kimberlite. Results to date have shown that higher diamond grades are associated with the Early Joli Fou equivalent kimberlite than with the Late Joli Fou equivalent kimberlite. The relationships between these two kimberlites types are illustrated in cross sections available on the Shore Gold website: www.shoregold.com.
Batches 39, 41, 42A, 42B, 43, 44, 45A and 45B (all from 235 metre level) have been processed on-site and the concentrates dispatched to the sorting laboratory for final diamond recovery. Results from these batches are pending. A total of 18,600 dry tonnes has been processed through the on-site DMS plant. All batches processed to date are classified as crater facies volcaniclastic kimberlites.
Kimberlite processed and diamond results for seven sample batches are listed in the table below. Grades are expressed in carats per hundred tonnes (cpht).

The four largest stones are: 19.68 (Batch 40, Off White), 11.57
(Batch 35B, Grey), 8.07 (Batch 38A, Off White) and 5.31 (Batch 36, Brown)
carats, respectively. Seventeen diamonds exceed two carats and 42 diamonds
exceed one carat, of which 22 are white, 10 are off-white, 9 are grey and 1 is
brown. A total of 94 diamonds exceed 0.5 carat. Seventy-three percent of the
total diamond parcel is classified white in colour, with a further 11 percent
classified as off-white. The diamond parcel includes 11 pink, 23 yellow and 14
amber stones. Ninety-nine percent of the carat weight of this parcel occurs in
diamonds greater than 1.18 millimetre square mesh.
Senior Vice President Exploration, George Read, states: "To date,
kimberlite bulk sample processing has produced a 2,120 carat diamond parcel.
The diamond parcel contains a significant proportion of large stones and an
abundance of white diamonds, which will contribute favourably to the average
value ultimately determined for the bulk sample diamond parcel. Among the most
recent batches processed we have recovered two stones of particularly high
value: 1) the 19.68 carat off white, fragment of a considerably larger stone,
recovered from Batch 40. The fresh breakage surface suggests that this stone
was broken during underground mining activities; and 2) the 4.77 carat white,
flawless octahedron recovered from Batch 38B. These stones confirm the
presence of large, high value diamonds in the Star Kimberlite. Photographs of
these two diamonds will be available this week on the Shore Gold website:
http://www.shoregold.com".
The diamond recovery procedure includes on site processing of kimberlite
through the modular dense media separator (DMS), after which DMS concentrates
are batch fed through an X-ray Flow-sort. In order to ensure the recovery of
low luminosity diamonds, the Flow-sort tailings are processed over a grease
table. Flow-sort and grease table concentrates are transported by a secure
carrier to SGS Lakefield Research for final diamond recovery. The SGS
Lakefield Research process includes drying, screening, magnetic separation,
manual sorting and diamond weighing and description. SGS Lakefield Research is
accredited to the ISO/IEC 17025 standard by the Standards Council of Canada as
a testing laboratory for specific tests.
Senior Vice President Exploration, George Read, Professional Geoscientist
in the Provinces of Saskatchewan and British Columbia, is the Qualified Person
responsible for the verification and quality assurance of analytical results.
The Star Diamond Project is designed to recover a parcel of at least
3,000 carats of diamonds to enable an accurate valuation of the stones. Up to
25,000 tonnes of kimberlite will be recovered from the shaft and drifts and
processed on site to produce this diamond parcel. Shore is a Canadian based
corporation engaged in the acquisition, exploration and development of mineral
properties. Shares of the Company trade on the TSX Venture Exchange under the
