    SASKATOON, Aug. 13 /CNW/ - George H. Read, P. Geo., Senior Vice President
Exploration and Development, is pleased to announce the seventh set of diamond
results from Phase 3 of the underground bulk sampling of the Star Kimberlite
(Phase 1 being the original 25,000 tonne bulk sample and Phase 2 being the
18,000 tonne bulk sample). The diamond recoveries total 724.39 carats from
5,580 dry tonnes processed. Included in this release are results for
15 kimberlite batches of a total of 87 kimberlite batches that have been
processed as part of the Phase 3 bulk sampling program. A total of
7,484 commercial sized diamonds (greater than 1.18 millimetre square mesh
screen), collectively weighing 717.18 carats, has been recovered from the
15 batches. Seventy-two diamonds greater than one carat have been recovered
and the four largest stones are: 12.32, 4.54, 4.47 and 4.21 carats,
respectively. In addition, 399 diamonds totaling 7.21 carats were recovered
down to 0.85 millimetre square mesh. The colour of 71 percent of the diamonds
has been classified as white, with a further 18 percent classified as
    These kimberlite batches were recovered from the Pense Kimberlite, which
was mined at the north-east end of the underground development, some
300 metres northeast of the shaft, within Shore's 100% owned portion of the
Star Kimberlite. All sampling of the Pense Kimberlite was completed on the
215 metre level which was accessed by a ramp from the 235 metre level where
most of the Star underground bulk sampling was completed. The lower grades
associated with Batches 213, 215, 218, 221, 222 and 223 are a function of a
localized zone of fine grained, ash-rich Pense Kimberlite. The pattern core
drilling program has shown that extensive volumes of coarse grained Pense
Kimberlite (similar in nature to the kimberlite associated with Batches 214,
217, 224, 227, 228, 229, 230, 231 and 232) occur to the east of this localized
fine grained zone. Results from the final Early Joli Fou, Cantuar and clean-up
batches will be reported once they become available from SGS Lakefield.

    batches are listed in the table below. Grades are expressed in carats per

    The four largest stones are: 12.32 (Batch 217, white), 4.54 (Batch 232,
grey), 4.47 (Batch 230, off white) and 4.21 (Batch 224, grey) carats
respectively. Twenty-two diamonds exceed two carats and 72 diamonds exceed one
carat, of which 28 are white, 28 are off white, 10 are grey, 5 are brown and
one is yellow. A total of 178 diamonds exceed 0.5 carat. Seventy-one percent
of this diamond parcel is classified white in colour, with a further
18 percent classified as off-white. Ninety-nine percent of the carat weight of
this parcel occurs in diamonds greater than 1.18 millimetre square mesh.
    Senior Vice President Exploration and Development, George Read, states:
"These results are the final batches of Pense Kimberlite processed for the
underground bulk sample. A total of 11,024 tonnes of Pense Kimberlite was
sampled underground and processed to recover a total of 1,403 carats, giving
an average grade for the Pense bulk sample of 12.73 cpht and a range of grades
from 3.54 (Batch 215) to 29.26 (Batch 205). We have achieved our objective of
this Pense bulk sampling exercise by obtaining a diamond parcel in excess of
1,000 carats, which will be used for diamond price estimation purposes for the
Pense Kimberlite. The diamond valuation of the total underground bulk sample
from Star is scheduled for the fourth quarter of 2007."
    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.
    The Star Kimberlite is currently being evaluated using a combination of
pattern core drilling, underground bulk sampling and large diameter drilling.
This evaluation program, with a budget of some $60 million, is intended to
determine the presence of a National Instrument 43-101 compliant Mineral
Reserve for the Star Kimberlite. Senior Vice President Exploration and
Development, 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. Shore is a Canadian
