SASKATOON, SK, Sep 15, 2004 (Canada NewsWire via COMTEX) --
George H. Read, P. Geo., Senior Vice President Exploration, is pleased to announce the sixth set of diamond recoveries from the Star Kimberlite. The diamond recoveries to date total 1,392.83 carats from 12,124 dry tonnes processed. These results are for five 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 1,706 commercial sized diamonds (greater than 1.18 millimetre square mesh screen), collectively weighing 263.01 carats, has been recovered from the treatment of 1,198.88 dry tonnes of kimberlite. Forty-one diamonds greater than one carat have been recovered and the four largest stones are: 14.60, 10.14, 7.68 and 6.23 carats, respectively. In addition, 213 diamonds (3.35 carats) were recovered down to 0.85 millimetre square mesh. The colour of 64 percent of these diamonds has been classified as white, with a further 21 percent classified as off-white.
These five kimberlite batches (of a total of 33 processed) have been mined from the Southeast drive (Batches 22, 24 and 25) and the North drive (Batches 21 and 23) 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 26, 27, 28, 29, 30, 31, 32 and 12A (all from 235 metre level) have been processed on-site and the concentrates dispatched to the sorting laboratory for final diamond recovery. A total of 13,991 dry tonnes has been processed through the on-site DMS plant. Results from these batches are pending. All batches processed to date are classified as crater facies volcaniclastic kimberlites.
Kimberlite processed and diamond results for five sample batches are listed in the table below. Grades are expressed in carats per hundred tonnes (cpht).
------------------------------------------------------------------------- Batch Location Diamonds Total Grade Largest No. (metres below Dry Number of (carats) (cpht) Stone surface) Tonnes Stones (carats) ------------------------------------------------------------------------- 21 235 m Level: N drive 226.29 337 32.89 14.53 1.29 ------------------------------------------------------------------------- 22 235 m Level: SE drive 268.71 460 50.05 18.63 3.41 ------------------------------------------------------------------------- 23 235 m Level: N drive 248.08 331 45.63 18.39 6.23 ------------------------------------------------------------------------- 24 235 m Level: SE drive 201.43 460 60.24 29.91 7.68 ------------------------------------------------------------------------- 25 235 m Level: SE drive 254.37 331 77.55 30.49 14.60 ------------------------------------------------------------------------- Total 1,198.88 1,919 266.36 22.22 -------------------------------------------------------------------------
The four largest stones are: 14.60 (Batch 25, White), 10.14 (Batch 25, White), 7.68 (Batch 23, White) and 6.23 (Batch 25, Grey) carats, respectively. Sixteen diamonds exceed two carats and 41 diamonds exceed one carat, of which 27 are white, 9 are off-white, 3 are grey and 2 are brown. A total of 86 diamonds exceed 0.5 carat. Sixty-four percent of the total diamond parcel is classified white in colour, with a further 21 percent classified as off-white. The diamond parcel includes 10 pink, 16 yellow and 6 amber stones. Over 98 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: "These latest results include a significant number of large stones and higher grades, particularly for Batches 24 and 25. The frequency of plus one carat stones in the Star Kimberlite will have a highly positive effect on the forthcoming diamond valuation. Results to date indicate an average grade of 15.83 cpht for the Early Joli Fou equivalent kimberlite (1,198 carats recovered from 7,570 dry tonnes)".
