But retired geology professor Dr. Bob Folinsbee says the property has the potential to be "the diamond find of the century." The site, known as Camsell Lake, is 220 km northeast of Yellowknife and 100 km south of the Lac de Gras area where BHP Minerals operates Ekati, Canada's first operating diamond mine. Winspear holds a 67-per-cent interest in the Camsell Lake site. Aber Resources of Vancouver holds the remainder: Aber also has a 40-per-cent interest in the Diavik site 35 km from Ekati. Rio Tinto pic and Aber hope to have the Diavik mine in production by 2002. Winspear president Randy Turner was a student of Folinsbee's, graduating from the University of Alberta in 1971. Turner, 49, was in Edmonton to speak to potential investors. Folinsbee, 81, U of A professor emeritus, is not associated with Winspear: "The Camsell Lake property is unique," Folinsbee said. Diamonds are found in kimberlite, a material formed as a result of volcanic upthrust from the earth's molten inner core. Most surface as carrot-shaped kimberlite "pipes" or dikes. At Camsell Lake, testing reveals a kimberlite body consisting of a cone sheet, Folinsbee said. "There is only one other kimberlite cone sheet in the world, discovered in 1924 in what is now Tanzania. It produces some of the largest diamonds mined in the world." The Bellsbank mine has operated for more than 50 years. The Camsell Lake cone sheet is almost identical and has the potential to produce significant quantities of large, gem quality stones. Turner stressed it is far too early to draw any comparisons to Ekati or Diavik. He said Winspear will begin larger-scale bulk sampling of a minimum 5,000-carrot sample. It will also do more test drilling next month as its Camsell Lake property. Once the results are known, Winspear would move to do a full feasibility study beginning late next year, Turner said. It has spent $4 million on the first round of bulk sampling and test drilling and a total of $12 million on the site to date, he added. A 200-tonne bulk sampling to two pits at the Camsell Lake site produced 228 carats of diamonds with a grade of 1.19 carats per tonne. The sample would indicate a value of $343 US per carat. By comparison, large-scale sampling from the Diavik site has produced diamonds with a grade of 1.09 carats per tonne with an average value of $120 per carat."
