SASKATCHEWAN – Denison Mines Corp
. says assays from winter drilling at the Gryphon D lens at the Wheeler River project show grades up 45% from previously released radiometric probe results. The project is owned 60% and operated by Denison. Cameco
and JCU Canada Exploration
hold 30% and 10%, respectively.

The best drill hole to date is WR-633D3 that returned 3.3% uranium oxide over 13.5 metres, 6.2% over 2.5 metres, and 1.3% over 3.0 metres within the D series lenses.
In 2015, Denison estimated the Gryphon deposit contains 43.0 million lb. of uranium oxide in 834,000 inferred tonnes grading 2.3% uranium dioxide. A cut-off of 0.2% U3
was used. The mineralization in the D lens was unknown at that time.
