Star Kimberlite Project-Progress Report
Jonathan Challis, President, is very pleased to report that preliminary diamond analyses derived from caustic dissolution for samples from eight out of the fifteen NQ drill holes completed on the Star Kimberlite earlier this year have now been received. The core samples represent split core intervals from the drill holes with half the core still available for further testing.
The drill program consisted of 16 vertical holes (15 NQ-size holes; core 1.875 inches in diameter, and one PQ-size hole; core 3.35 inches in diameter) that intersected kimberlite over intervals ranging from 30 metres in hole 011 to 145 metres in hole 007, including intra-kimberlite sediments. Intervals of continuous kimberlite ranged from 5 metres in hole 011 to 128 metres in hole 009. The results demonstrate the widespread occurrence of diamonds within the Star Kimberlite, which has been determined by drilling and geophysical modelling to be in excess of two square kms in areal extent.
The caustic dissolution analyses were completed by the 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 kg in weight.
The most striking feature of these results is the dramatic increase in macrodiamond content per kg of sample compared to previous NQ drilling where the entire core was sent for analysis. The total macrodiamond count per kilogram of sample is 77% higher in the current samples over the entire sampled interval, including sediment, and 104% higher for intervals of continuous kimberlite than previous NQ results. This is also reflected in the projected grade for sampled intervals. Even though the sample size is not yet sufficient to come to any statistically valid conclusions, normalizing sample weights to 100 tonnes produces projected grades for several intervals at over 30 carats per 100 tonnes. Drill hole 009 has outstanding results with the projected grade ranging from 35 carats per 100 tonnes for the entire hole, to 133 carats per 100 tonnes for a 31 metre interval. Five diamonds measured greater than 1.0 mm (14%) in one dimension.
The total results for holes Star 003, 004, 006, 007, 009, 010, 011 and 015, along with notable sub-intervals* are summarized as follows:
Hole No. Sampled Weight (kg) Sampled Interval (m) No. of Micros <0.5 mm No. of Macros >0.5mm Total Diamonds Projected Weighted Average Grade(cts/100t)

TOTALS 942.3 674.4 160 37 197 18
*Note: the lesser sub-intervals reported may be contained within the larger sub-intervals and are meant to illustrate the potential for the occurrence of high-grade sections within the Star Kimberlite body. The occurrence of such higher grade kimberlite is important for the overall economics of the project.
Holes drilled and not yet analyzed intersected kimberlite ranging from 30 meters in hole 005 to 112 meters in hole 013. Diamond analysis for samples from the split core from these holes is in progress. In addition, logging and diamond analysis by caustic dissolution of the entire PQ-size core hole drilled near holes 004, 007 and 009 is also in progress.
The Star Kimberlite consists of a variety of primary, volcanoclastic crater facies covering an area in excess of two square kms with thicknesses nearing 150 meters on the west and continuing north, east and south to thickness in excess of 30 meters. Preliminary estimates of continuous diamond-bearing kimberlite exceed 200 million tonnes determined by drill holes and substantiated by geophysical modelling.
Once the remainder of the results have been received, a comprehensive news release will be issued. In light of the encouraging results to date the company is proceeding with Phase II, 2000 drill program to further delineate kimberlite thickness and dimension and select the most appropriate site for a large-tonnage sample.
The Star Kimberlite is located 60 km east of Prince Albert, Saskatchewan in one of the largest diamond-bearing kimberlite fields in the world.
