“NWT Uranium Corp. (TSX-V: NWT; OTCBB: NWURF) is pleased to provide an update for its shareholders regarding the exploration activities of Niger Uranium Limited, of which NWT is the largest shareholder with a 30.5% ownership position.

Niger Uranium reports that a resource calculation is underway for a 16,400-foot by 2,950-foot (5,000-meter by 900-meter) area at the In Gall property, which contains a continuous near-surface layer with a mean borehole interval grade of 146 parts per million (ppm) equivalent U₃O₈ (eU₃O₈) over 3.9 feet (1.2 meters), as detailed in a press release dated May 14, 2008. This grade represents an increase of 20% over previously reported grades, as a result of final calibration of the radiometric probe. Niger Uranium expects the resource calculation to be completed in June. Step-out drilling is planned to significantly extend the resource.

In addition, one borehole outside of the defined “resource area” drilled the same layer 3.7 miles (6.0 kilometers) along strike and returned an intersection of 15.0 feet (4.6 meters) with a grade of 172 ppm eU₃O₈, using radiometric probing, illustrating the potential for thicker development of the mineralized layer. Similar high-tonnage open-pittable surface deposit projects within Africa typically have cut-off grades of between 40 and 80 ppm U₃O₈.

Drilling to date has only tested approximately 20% of the historically delineated mineralized area. The mineralization remains open and historical maps indicate that it could extend up to 9.3 miles (15.0 kilometers) to the west. Niger Uranium reported that it will commence extension drilling in June to significantly expand the resource area.

For further information on Niger Uranium’s 2008 exploration program and complete details of the borehole intersections, please visit the company’s web site at www.niger-uranium.com, where the complete press release from May 14, 2008 can be viewed.

NWT contributed the Irhazer and In Gall properties to Niger Uranium, as detailed in a press release dated July 26, 2007.

NWT owns 30.5% of Niger Uranium following Niger Uranium’s acquisition of a significant interest in private South American uranium explorer, UrAmerica plc. On closing of the transaction, NWT acquired a stake in UrAmerica of approximately 6.3% based on its percentage interest in Niger Uranium. If warrants issued as part of the agreement are exercised, NWT would then hold 10.3% of UrAmerica. For more information on the acquisition, please visit Niger Uranium’s web site.

Quality Assurance

Drilling was completed under the direction of MSA Geoservices of South Africa. All boreholes were vertical and drilled by the tri-cone method and probed with a Robertson gamma tool which was calibrated by Terratec Geoservices at the Medusa facility in the Netherlands. Final calibration resulted in a conversion factor of 0.157 ppm eU₃O₈ per radiometric count. Additional validation of the gamma tool results is provided by the results of the XRF analyses on samples from 15 boreholes within the “resource area.” All boreholes were drilled by the tri-cone method.

Qualified Person

The information contained in Niger Uranium’s announcement has been reviewed by Keith Kenyon (MSc. AUS IMM), Geochemical Consultant to Niger Uranium. He is the Qualified Person overseeing the geochemical exploration on the In Gall-Irhazer licenses.
