STAR KIMBERLITE PROJECT- STAR 020 YIELDS ESTIMATED 61.0 CARATS PER 100 TONNES OVER 311.6 METRES. STAR 023 YIELDS ESTIMATED 64.1 CARATS PER 100 TONNES OVER 118.1 METRES
Jonathan Challis, President, is very pleased to report that diamond analyses for the five NQ sized diamond drill holes (Star 017, 018, 019, 020 and 023) from the 2000 Phase II drill program on the Star Kimberlite property have now been received. The results for Star 020 only include the NQ section of hole, and not the deeper BQ core. A total sample of 626 kilograms (kgs) of split kimberlite core were processed, taken over a continuous interval of 311.6 metres from a depth of 87.6 metres below surface to a depth of 399.2 metres. This sample resulted in an estimated diamond grade of 61.0 carats per 100 tonnes (cts/100t). The remaining 235 metres of core (representing the intersection from 399.2 metres to 634.2 metres) from this hole were drilled using a BQ sized drill (36.5mm diameter).
Within the sampled interval, higher-grade sections were found including an intersection of 25.6 metres with a grade of 435 cts/100t and 133 metres with a grade of 116 cts/100t.
A total of 3,422 kgs of split core have now been analysed from 20 NQ holes (47mm diameter) and 1 PQ hole (85mm diameter) that were drilled during 2000 and early 2001 resulting in the recovery of 782 diamonds, including 197 macros, weighing 1.244 carats for an average grade of 36.3 cts/100t.
DRILL HOLE RESULTS
Hole No. Sampled Weight (kg) Sampled Interval (m) No. of Micros <0.5 mm No. of Macros >0.5mm Total Diamonds Projected Grade(cts/100t)
Star 017 142.0 80.9 4 5 9 32.9
Star 018 99.1 54.5 6 4 10 10.0
Star 019 93.6 54.2 6 5 11 44.7
Star 020 626.0 311.6 125 46 171 61.0

Total 2000 & 2001 3,422 1,781.8 585 197 782 36.3
The caustic dissolution analyses were completed by Kennecott Canada Inc.’s ISO Guide 25 Process Registered Thunder Bay Laboratory using a diamond recovery sieve size of 150 microns (100 mesh) and were done on split drill core samples averaging 10 kgs in weight; the other half of the drill core has been retained.
Included within the total of 46 macro diamonds that were recovered from Star 020 are 15 stones with at least one dimension equal to, or greater than, 1.0 mm. The 46 macros account for approximately 87% of the weight of diamonds recovered from Star 020, and the 15 macros greater than 1 mm represent approximately 71% of the total weight of diamonds recovered in this hole (equivalent to a grade of 44 cts/100 tonnes).
The four largest stones recovered in this hole have dimensions of 1.49x1.41x1.29mm; 1.52x1.25x1.15mm; 1.49x1.33x0.94mm; and 1.46x1.27x0.96mm.
The Company is delighted with the results from these five holes, representing some of the highest values reported in a single drill hole over a thickness in excess of 100 metres from the Star program. (Holes Star 002 and 005 reported values of 121 cts/100 tonnes and 97 cts/100 tonnes over intersections of 31 metres).
Since the start of the exploration program over the Star kimberlite in 1996, a total of 26 diamond drill holes with a total sample weight of 4,623 kgs have been analysed, resulting in the recovery of 1.477 cts of diamonds. In the most recent program covering 2000 and 2001, 84% of the weight of stones recovered has been in those larger than 0.5 mm, and those larger than 1.0 mm have represented approximately 60% of the total weight of recovered diamonds. Shore will be retaining an independent firm of diamond experts to analyse the recovered diamond population to produce a probability distribution for the stones and to determine a preliminary view of the likely commercial grade of the Star kimberlite.
The evaluation of the Star kimberlite in conjunction with the Geological Survey of Canada is proceeding, and further news on this program will be reported in due course.
Work is continuing with the evaluation of alternative methods for extracting a representative bulk sample from both the deeper portions of the kimberlite in the vicinity of Star 020, and from the upper portions where the thickness is greater than 100 metres. This will enable a preliminary estimate to be made of both a possible commercial grade and a range of values for the diamonds contained therein. This will consequently enable an initial estimate of the likely economic value of this massive kimberlite body to be made.
Preliminary estimates of continuous diamond-bearing kimberlite exceed 500 million tonnes with an average thickness of 88 metres, based on a minimum cut-off thickness of 30 meters, indicated by geophysical modelling and substantiated by drill holes.
