Denison Mines reports initial summer drilling results from Gryphon zone Denison Mines reports initial results from the 2014 summer drilling program at the Gryphon zone on the Wheeler River property in the Athabasca Basin of Saskatchewan. Ten of a planned 20 drill holes have been completed to date, including the extension of two historic drill holes. The extension drill holes ZK-04EXT and ZK-06EXT, along with WR-565, have tested geological targets up dip of the main mineralized zones on the original discovery section. The other seven holes are systematic 50 metre step-outs down dip and along strike of the previously reported mineralization in WR-556 and WR-560. The highlight from the summer program so far is drill hole WR-569A which intersected a wide zone of alteration and mineralization with several high grade intervals, including 9.41% eU3O8 over 3.7 metres and 5.27% eU3O8 over 5.9 metres. WR-569A is located 40 metres along strike southwest and 40 metres up dip of drill hole WR-556 which intersected 15.3% U3O8 over 4.0 metres and was the Gryphon zone discovery drill hole.
