:: Denison Runs Ore Through White Mesa Mill

Denison Mines of Toronto has begun processing conventional ore at its 100%-owned White Mesa mill near Blanding. Testing of the grinding circuit began on April 21, and the first ore from the Tony M mine reached the leaching circuit on April 28.

Over the next 30 to 45 days, the mill will be processing uranium-only ore and will then switch to uranium-vanadium ores from the company's Colorado Plateau mines. Currently, there are approximately 135,000 tonnes of ore from Denison's various mines on the stockpile at the mill.

The modernization of the mill's vanadium circuit and the relining of tailings Cell 4A is continuing on schedule. Ron Hochstein, Denison's president and COO, stated, "This is a great achievement by the staff and contractors at White Mesa who have modernized the facility while continuing operations on alternate feed material, and without a lost time accident."

Denison is projecting production of between 1.4 and 1.7 million lb of U3O8 and 3.0 to 4.0 million lb of vanadium pentoxide from White Mesa in 2008. Currently, Denison has approximately 170,000 lb of U3O8 in inventory from the processing of alternate feed materials in the first four months of 2008.
