SASKATOON, SK, Oct. 19 /CNW/ - George H. Read, P. Geo., Senior Vice President Exploration, is pleased to announce the eighth set of diamond recoveries from the Star Kimberlite. The diamond recoveries to date total 1,811.73 carats from 14,575.94 dry tonnes processed. These results are for six 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 1,815 commercial sized diamonds (greater than 1.18 millimetre square mesh screen), collectively weighing 219.02 carats, has been recovered from the treatment of 1,446.61 dry tonnes of kimberlite. Twenty-nine diamonds greater than one carat have been recovered and the four largest stones are: 8.08, 6.28, 3.12 and 3.07 carats, respectively. In addition, 188 diamonds (3.05 carats) were recovered down to 0.85 millimetre square mesh. The colour of 76 percent of these diamonds has been classified as white, with a further 10 percent classified as off-white.
These six kimberlite batches (of a total of 43 processed) have been mined from the Southeast drive (Batches 12A, 32 and 33) and the North drive (Batches 30, 31 and 34) 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 35A, 35B, 36, 37, 38A, 38B, 39 and 40 (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 16,492 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 four sample batches are listed in the table below. Grades are expressed in carats per hundred tonnes (cpht).

The four largest stones are: 8.08 (Batch 33, Off White), 6.28 (Batch 31,
Off White), 3.12 (Batch 12A, White) and 3.07 (Batch 3 1, White) carats,
respectively. Ten diamonds exceed two carats and 29 diamonds exceed one carat,
of which 22 are white, 4 are off-white, 2 are grey and 1 is brown. A total of
75 diamonds exceed 0.5 carat. Seventy-six percent of the total diamond parcel
is classified white in colour, with a further 10 percent classified as
off-white. The diamond parcel includes 2 pink, 4 yellow and 11 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: "We now have
diamond results for over 10,000 tonnes of Early Joli Fou kimberlite and the
average grade for this kimberlite type remains just over 16 cpht (1,617 carats
from 10,022 dry tonnes). To date, this bulk sampling program has consistently
produced an abundance of large stones and a high proportion of white goods.
The frequency of large stones and the proportion of white goods are very
significant characteristics of the Star diamond population, both of which will
significantly increase the average diamond value".
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
