Star Kimberlite Project- Star 016 Yields Estimated 31.2 Carats Per 100 Tonnes
Jonathan Challis, President, is very pleased to report that diamond analyses for the remaining PQ sized diamond drill hole (Star 016) from the 2000 Phase I drill program on the Star Kimberlite property has now been received. A total sample of 750.9 kilograms (kgs) of split kimberlite core were processed, taken over a continuous interval of 144.2 metres, resulting in an estimated grade of 31.2 carats per 100 tonnes (cts/100t). A total of 2,245.4 kgs of core has now been analysed from the 15 NQ holes (1.875 inch diameter) and the one PQ hole (3.35 inch diameter) that were drilled in the first half of 2000, resulting in the recovery of 523 diamonds, including 120 macros, weighing 0.621 carats for an average grade of 27.8 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 016 (PQ) 750.9 144.2 159 44 203 31.2
2000 Total (NQ + PQ) 2,245.4 1,162.5 403 120 523 27.8
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 8 kgs in weight; the other half of the drill core has been retained.
Included within the total of 43 macro diamonds that were recovered from Star 016 are 10 stones with at least one dimension equal to, or greater than, 1.0 mm. The largest stone in this hole, a fragment, measures 2 mm and weighs just over 0.04 carats. The macros account for 23% of the number of stones recovered from the 2000 Phase I drill program, but 79% of the total weight of stones recovered. One sample weighing 10 kgs, taken over a 1.4 metre interval towards the bottom of the hole, returned 4 macros, each having at least 1 dimension greater than 1 mm. Star 016 is located approximately 125 metres south west of Star 004 and 150 metres south east of Star 020.
The Company is delighted with the results received to date, representing a substantial increase in the recovered weight of diamonds as compared with the 1996 and 1997 drill programs. If the results obtained from the drilling performed in 1996 (NQ holes) is compared with the results from the 2000 program (NQ only), the sample size in 2000 increased by 290%, but the carat weight of the stones recovered increased 620% despite the use of a larger cut-off sieve in the 2000 program. Comparing the 1997 PQ results against the 2000 PQ results, the sample weight decreased 8% in 2000, but the recovered carat weight of diamonds increased by 31%. Furthermore, all drill holes to date contain both micro and macro stones.
Phase II of the 2000-2001 drill program is currently underway. The program will test the extent of the Star Kimberlite to the northeast and the southeast of the currently defined area of over 4 square kilometres and in the vicinity of Star 020, which recently intersected over 539 metres of continuous kimberlite in a vertical hole. The evaluation of alternative methods of obtaining a representative bulk sample from both the deeper portions of the kimberlite in the vicinity of Star 020, and from the entire body to enable an estimate to be made of the likely economic value of this massive kimberlite body is in progress. Preliminary estimates of continuous diamond-bearing kimberlite exceed 400 million tonnes with a minimum thickness of 30 meters, indicated by geophysical modelling and substantiated by drill holes.
