SASKATCHEWAN – Toronto-based Denison Mines has already reported winter drilling success at two of its joint ventures – Mann Lake and Wheeler River – near the MacArthur River mine on the east side of the Athabasca Basin. Denison holds a 30% interest in Mann Lake with Cameco (52.5% and operator) and Areva Resources Canada (17.5%). At Wheeler River, Denison holds a 60% interest and is operator; the balance belongs to Cameco (30%) and JCU (Canada) Exploration (10%).
The best result from Mann Lake was 3.5 metres of 9.8% eU3O8 (radiometric equivalent uranium from a total gamma down-hole probe). The winter drill program will test for extensions of uranium mineralization from holes drilled in 2014.
At Wheeler River, the best hole returned 9.0% eU3O8 over 4.6 metres. The current drill program aims to extend the Gryphon zone of basement hosted mineralization discovered in 2014. The zone consists of multiple stacked lenses with variable thicknesses that plunge to the northeast. As defined by drilling last year, the zone is 350 metres long and 60 metres wide. Twenty-two holes are planned this winter.
