Denison Mines has reported the assay results from the remaining holes of the summer drill program on the Wheeler River property in Saskatchewan.

Significant results included WR-342 which returned 12.41% U3O8 over 10m and WR-345, which intersected 5m grading 16.21% U3O8, both of which were in Zone A of the Phoenix Trend.

In Zone B, WR-347 returned 5.44% U3O8 over 6.5m and WR-348 intersected 4.87% U3O8 over 7m .

Chemical analyzes were completed by SRC Geoanalytical Laboratories of Saskatoon, Saskatchewan and were a combination of geochemical and assay methods.

The assay grades are reported at a 0.05% U3O8 cut-off in which no significant results were returned from holes WR-336, WR-338, WR-339, WR-340, WR-350, and WR-352.

WR-337 will continue to be reported as equivalent grade due to poor core recovery.

Denison has also reported that work on a technical report, which is being prepared in accordance with National Instrument 43-101 (NI 43-101), of estimates of the mineral resources at the Phoenix Zone A and B deposits, is progressing well.

A block model has been constructed, and now that final assays have been received, estimates of mineral resources are being completed using both ID Squared and Kriging routines.

The Wheeler River joint venture is scheduled to meet in November to plan and approve the 2011 exploration and development program.

Denison is the operator and holds a 60% interest in the Wheeler River Property.
