SASKATCHEWAN – Toronto-based Denison Mines says that drilling continues to intersect multiple zones of high grade mineralization from the Gryphon deposit at the Wheeler River uranium project in the Athabasca Basin. The project is owned by Denison (60% owner and operator), Cameco Corp. (30%), and JCU (Canada) Exploration (10%).

Nine infill and delineation drill holes have been completed on the Gryphon deposit’s A, B and C series lenses, as part of the infill drilling program to bring the current estimated inferred resources into the indicated category. Results include these highlights:

  • 3% uranium oxide over 25.3 metres (including 3.3% eU3O8over 7.8 metres) in drill hole WR-604D1;
  • 1% eU3O8over 5.9 metres in drill hole WR-692;
  • 3% eU3O8over 9.3 metres in drill hole WR-564D1;
  • 0% eU3O8over 7.0 metres (including 3.6% eU3O8 over 5.7 metres) in drill hole WR-610D1; and
  • 9% eU3O8over 8.4 metres (including 2.5% eU3O8 over 6.2 metres) in drill hole WR-570D1.

Denison says the results are consistent with the current inferred block model.

The Wheeler River summer program includes field activities, environmental studies and engineering data collection in preparation for a pre-feasibility study due next year.

Details of the recent drilling program are available at in the news release dated July 24, 2017.
