SASKATOON, SK, TORONTO, Jan. 13 /CNW/ - George H. Read, P. Geo., Senior Vice President Exploration, is pleased to announce the twelfth set of diamond recoveries from the Star Kimberlite. The diamond recoveries to date total 3,092.25 carats from 21,994.62 dry tonnes processed. These results are for eight 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 2,954 commercial sized diamonds (greater than 1.18 millimetre square mesh screen), collectively weighing 349.92 carats, has been recovered from the treatment of 2,256.90 dry tonnes of kimberlite. Forty-six diamonds greater than one carat have been recovered and the four largest stones are: 5.15, 4.15, 3.97 and 3.70 carats, respectively. In addition, 302 diamonds (4.70 carats) were recovered down to 0.85 millimetre square mesh. The colour of 65 percent of these diamonds has been classified as white, with a further 12 percent classified as off-white.
These eight kimberlite batches (of a total of 70 processed) have been mined from the Southeast drive (Batches 50, 51A, 51B and 54) and the North drive (Batch 52, 53, 55A and 55B) 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 kimberlite types are illustrated in cross sections available on the Shore Gold website: www.shoregold.com.
Batches 56A, 56B, 57A, 57B, 58 59A, 59B, 60, 61, 62, 63, 64 and 65 (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 24,819 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 eight sample batches are listed in the table below. Grades are expressed in carats per hundred tonnes (cpht).

The four largest stones are: 5.15 (Batch 55A, Off White), 4.15
(Batch 55A, Grey), 3.97 (Batch 53, Brown) and 3.70 (Batch 51B, Grey) carats,
respectively. Eleven diamonds exceed two carats and 46 diamonds exceed one
carat, of which 14 are white, 11 are off-white, 14 are grey, 3 are brown,
3 are yellow and one is amber. A total of 112 diamonds exceed 0.5 carat.
Sixty-five percent of this diamond parcel is classified white in colour, with
a further 12 percent classified as off-white. The diamond parcel includes
15 yellow, 6 pink, and 8 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: "Shore has
achieved the goal of recovering a 3,000 carat parcel of diamonds from the Star
Kimberlite. The valuation of this 3,000 carat parcel will commence as soon as
all the diamonds have been acid cleaned at a specialized facility in Antwerp,
Belgium. Arrangements have been made with a number of independent, expert
diamond valuators who will examine the 3,000 carat parcel and determine the
average, 'run-of-mine', US dollar per carat value for the diamonds contained
in this parcel. The result of the valuations will be published shortly after
it is made available to Shore. It is anticipated that the result of the
valuations will be published during February 2005. Diamond results are still
awaited from some 4,000 tonnes of Early Joli Fou kimberlite and the
anticipated diamond recoveries from this material will result in a final
diamond parcel of considerably more than 3,000 carats. Shore geologists are
confident that the abundance of large stones and the frequency of white goods
will favourably elevate the average value of the star diamond parcel."
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 was designed to recover a parcel of at least
3,000 carats of diamonds to enable an accurate valuation of the stones. Shore
is a Canadian based corporation engaged in the acquisition, exploration and
development of mineral properties. Shares of the Company trade on the TSX
Exchange under the trading symbol "SGF".
