Denison Mines Corp. on March 27 announced an updated resource estimate for the Midwest joint venture uranium project in northern Saskatchewan.

The project is owned 25.17% by Denison, 69.16% by Orano Canada Inc. and 5.67% by OURD (Canada) Ltd.

Using a cutoff grade of 0.1% triuranium octoxide, the project's indicated resources increased by about 2.1 million pounds to 50.8 million pounds of U3O8 hosted within 1.0 million tonnes at 2.3% U3O8.

Total inferred resources rose by 13.5 million pounds to 18.2 million pounds of U3O8 contained within 846,000 tonnes at 1.0% U3O8.

The project is host to the high-grade Midwest Main and Midwest A uranium deposits, which lie along strike and within six kilometers of the J Zone deposit and Huskie discovery on Denison's 64.22%-owned Waterbury Lake project.
