SASKATCHEWAN – Denison Mines Corp. of Toronto has received the last of the assays from the summer drill program on the new Gryphon zone at the Wheeler River property between the Key Lake mill and McArthur River uranium deposit in the  Athabasca Basin. The highest one comes from hole WR-573D1 that intersected 22.2% U3O8 over 2.5 metres. That is the best intersection to date from the zone.

Another noteworthy hole was WR-574 that returned 14.6% U3O8 over 2.0 metres. This hole also cut three other intersections: 5.0% over 2.0 metres, 1.5% over 1.0 metre, and according to the downhole probe 1.0 metres of 1.2% eU3O8. All other results were results from chemical assaying.

In a news release, the company said, “Mineralization at Gryphon is hosted in basement gneisses, ranging from 100 to 250 metres below the sub-Athabasca unconformity. The zone currently measures 350 metres long (along the plunge) by 60 metres wide (across the plunge) and consists of multiple stacked lenses with variable thicknesses that plunge to the northeast and remain open in both plunge directions.”
