NWT announces positive results from drilling at Niger Uranium's In Gall property

About this update from Captor Capital Corp

TORONTO, April 28 /CNW/ - 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 32% ownership position. In a press release dated April 17, 2008, Niger Uranium revealed initial downhole radiometric logging results for the Phase 1 drilling program at In Gall. Of note, drilling at target 17 has delineated a 16,400-foot by 2,950-foot (5,000-meter by 900-meter) near-surface uranium-mineralized layer, which remains open to the west. Radiometric probe data shows the layer has an average thickness of 3.9 feet (1.2 meters) and a grade of 122 parts per million (ppm) equivalent U(3)O(8) (eU(3)O(8)) based upon data from 32 boreholes drilled on a 820-by-1,300 foot (250-by-400 meter) grid. The probe data indicates the grade and thickness of the layer is consistent, with 32 intersections returning values ranging from 63 ppm eU(3)O(8) over 2.2 feet (0.7 meters) to 177 ppm eU(3)O(8) over 5.9 feet (1.8 meters). Results of x-ray fluorescence (XRF) analysis on samples from the same boreholes indicate higher grades of up to 238 U(3)O(8) over 6.5 feet (2.0 meters). Historical data suggests the zone extends over 9.3 miles (15 kilometers) to the west of the area drilled to date, highlighting the potential for what Niger Uranium classifies as a "considerable open-pittable resource." The Phase 1 drill program commenced in January 2008 with an expected 32,800 feet (10,000 meters) planned and 13,450 feet (4,100 meters) completed to date. Drilling has focused on the above-mentioned target 17, where a mineralized layer measuring 2,952 feet (900 meters) wide, with a minimum strike length of 16,404 feet (5,000 meters) and potential for significant expansion extension to the west, has been identified. Niger Uranium plans to complete several step-out fence lines to extend the currently delineated mineralized area. In late April, Niger Uranium expects to commence drilling to follow up on surface grab samples within the In Gall and Irhazer Licenses, which returned up to 0.98% U(3)O(8) as reported on January 29, 2008. Producing mines and deposits in Niger typically grade from 0.1% to 0.42% U(3)O(8), with the highest grades being mined at greater depths.

NWT contributed the Irhazer and In Gall properties to Niger Uranium, as detailed in a press release dated July 26, 2007. Quality Assurance Drilling is being carried out by Esafor Drilling under the supervision of MSA Geo Services of South Africa. All boreholes are vertical and drilled by the tri-cone method and probed using a Robertson Geologging gamma tool, calibrated by Terratec Geoservices in Germany to provide equivalent uranium grades expressed as eU(3)O(8). To support the probe data, borehole samples were sent to SGS Lakefield for XRF analysis for U(3)O(8). Samples were all one meter in length and taken at mineralized intervals as indicated by the probe data. The XRF U(3)O(8) grades are significantly higher than those obtained from radiometric probing for the same intervals. This is most likely to be a result of positive disequilibrium which results in the underestimation of grade if determined by radiometric proving. If this is verified by additional drilling and sampling, a significant increase of grades reported by radiometric probing can be expected. Qualified Person The information contained in Niger Uranium's announcement has been reviewed by Keith Kenyon (MSc. AUS IMM), Geochemical Consultant to Niger Uranium.
