Will Purcell Peter Dasler's Canalaska Uranium Ltd. (CVV) lost 12 cents to $1.08 on 610,000 shares. Canalaska and De Beers Canada are drilling their Athabasca diamond project in Saskatchewan. (De Beers has an option to earn a 90-per-cent interest by spending $20.4-million over seven years, although Canalaska can hold it to 70 per cent by paying $5.67-million of the final $17-million in exploration expenses.) The co-venturers will be drilling 11 targets this fall with "the balance" of the anomalies to be drilled after the lakes and marshes freeze. It is unclear how many targets will be drilled this winter but there are plenty to choose from: Canalaska and De Beers have 85 magnetic anomalies enclosing 258 discrete targets on the property. Most of the larger anomalies will have to wait until winter as they lie under water. That list includes an 18-hectare feature that would be big news if it proves to be a diamond-bearing kimberlite pipe.
