SASKATCHEWAN – Denison Mines of Toronto reports a successful conclusion to its winter exploration drilling program in the Athabasca Basin. A total of 30,400 metres was completed in 32 holes on projects operated by Denison and its joint venture partners.
At the Wheeler River uranium property the results of 26 holes expanded the Gryphon zone located about 3 km northwest of the high grade Phoenix uranium deposit. The Gryphon zone grew up- and down-plunge as well as up-dip on two sections. The best results was hole WR584B that returned 9.0% U3O8 over 4.6 metres in the up-plunge direction.
Wheeler River is a joint venture of Denison (60% and operator), Cameco (30%) and JCU (Canada) Exploration (10%).
Drilling at Mann Lake expanded a zone of unconformity hosted uranium, said Denison. A total of 11 holes were completed there, including hole MN-066-01 that cut 3.5 metres of 9.8% U3O8 at the unconformity. The final hole of the season was abandoned because of spring breakup; it will be completed in June.
Mann Lake is a joint venture of Cameco (52% and operator), Denison (30%) and Areva Resources Canada (17.5%).
Denison participated in drilling programs on seven other properties last winter. The most encouraging results came from Hatchet Lake where a zone of intense basement clay alteration with elevated uranium values was extended. Eight holes completed at Crawford Lake confirmed the presence of an alteration zone along a 2,400-metre strike length that was first drilled last year.
