Denison Reports 45 Percent Increase in Uranium Grades from Latest Assay Results

Denison Mines (“Denison” or the “Company”) (TSX:DML)(NYSE MKT:DNN) is pleased to report a significant increase in uranium grades from previously released preliminary radiometric probe results, following the receipt of uranium assays from the Company’s winter 2017 drilling program on the 60% owned Wheeler River project.
The winter 2017 exploration program involved a combination of infill drilling at the Gryphon deposit and resource expansion exploration drilling to the northwest of the Gryphon deposit. The Wheeler River project is host to the high-grade Gryphon and Phoenix uranium deposits, and is the largest undeveloped high-grade uranium project in the infrastructure rich eastern portion of the Athabasca Basin region in northern Saskatchewan.
The Company currently reports preliminary radiometric equivalent grades (“eU₃O₈“), derived from a calibrated downhole total gamma probe, during its exploration programs and subsequently reports definitive assay grades following sampling and geochemical analysis of the mineralized drill core.
Dale Verran, Denison’s Vice President of Exploration, commented:

“This set of Gryphon assay results have exceeded expectations – particularly for drill hole WR-633D3, which now ranks as the best hole to date in the D series of lenses. These results re-emphasize the potential of the D series lenses to add meaningful resources to the Gryphon deposit, ahead of a planned update to the resource estimate for the project.
This summer, in addition tothe ongoing infill drillingat Gryphon, we are planning to continue to explore the D lenses with the objective of defining high-grade zones and maximizingtheindicated resources that will be included in the upcoming PFS.”
