TORONTO, ONTARIO–(Marketwired – Nov. 2, 2017) – Denison Mines Corp. (“Denison” or the “Company”) (TSX:DML)(NYSE American:DNN)(NYSE MKT:DNN) is pleased to report the extension of new high-grade unconformity-hosted uranium mineralization located up-dip and approximately 250 metres along strike to the northeast of the basement-hosted Gryphon deposit, on the Company’s 60% owned Wheeler River project. Preliminary radiometric equivalent grades (“eU3O8“) from drill hole WR-670D2 are highlighted by an interval of 4.3% eU3O8 over 4.3 metres, from mineralization occurring immediately above the sub-Athabasca unconformity. This result adds to previous unconformity mineralized intercepts that include 5.0% eU3O8 over 4.7 metres in drill hole WR-689D3 and 1.2% eU3O8 over 1.4 metres in drill hole WR-690D3 (see Denison’s press release dated August 30, 2017). The new zone of “E series” unconformity mineralization now extends approximately 80 metres horizontally along the unconformity and remains open along strike to the northeast and southwest.
