In the fall of 2000, a ground resistivity survey was completed in the vicinity of Pipe 29/30 and Pipe 28. This type of survey has been used very successfully in other parts of the province to locate thicker areas of the kimberlite, and lesser magnetic kimberlite. As a result, several drill targets were selected from the resistivity data and the sites prepared for drilling.
In July and August 2002, three HQ-size (2.5 inches diameter) core holes were completed on Pipe 29/30. Hole WSL-8 was spotted 250m east of WSL-5 on a weak resistivity anomaly and failed to interesect any significant kimberlite. Drill holes WSL-9 and WSL-10 were drilled on a line between WSL-3 and WSL-5, 200m and 100m northwest of WSL-3 respectively. WSL-9 intersected approximately 75m of kimberlite and WSL-10 intersected 107m of kimberlite-the thickest to date on 29/30.
25 random samples from WSL-10 were sent to the Saskatchewan Research Council laboratory in Saskatoon for diamond recovery using caustic fusion. The result was the recovery of 126 diamonds from 170kg of sample material, including diamonds with one dimension larger than 0.5mm. In terms of diamonds recovered per kg of sample, these are the best results to date at Candle Lake and among the highest in the province.
The remaining samples will be processed once the property is transferred to Great Western Diamonds Corp. - the wholly-owned subsidiary of Great Western Minerals created to focus solely on diamond exploration. |
