Drilling Report

Niger Uranium Limited 17 April 2008 For immediate release 17 April 2008 Niger Uranium Limited ('Niger Uranium' or 'the Company') Drilling Update Further positive results from the In Gall license area, Niger Niger Uranium, the uranium focused exploration and investment company with interests in Niger and Namibia, is pleased to announce its initial downhole radiometric logging results for the drilling programme on the Company's 100% owned In Gall license in Niger. Highlights •Drilling at Niger Uranium's In Gall license, at target 17 has delineated a near surface uranium-mineralized layer with dimensions of 5,000 metres by 900 metres and open to the west. •Radiometric probe data shows the layer has an average thickness of 1.2 metres and a grade of 122 ppm eU3O8 based upon data from 32 boreholes drilled on a 250 by 400 metres grid. •The probe data shows that grade and thickness is very consistent; the 32 intersections ranged from 63 ppm eU3O8 over 0.7 metres to 177 ppm eU3O8 over 1.8 metres. Results of XRF analysis on samples collected from the same boreholes indicate higher grades, up to 238 ppm U3O8 over 2.0 metres. •The layer is gently dipping and exposed at surface and historical data suggests this zone extends over 15 kilometers to the west of the area drilled to date, highlighting the potential for a considerable open-pittable resource. •At other target areas within the Company's In Gall and Irhazer Licenses, a survey comprising 1,500 radon detectors will be completed by Stratamodel of the USA. Results from this survey are expected to delineate 'concealed' uranium deposits that may be present along major structures. In the interim, step-out drilling will commence at target 10 where an earlier lone scout-drilling borehole highlighted an intersection of 9.2 metres grading 105 ppm eU3O8. Ian Stalker, Deputy Chairman, said: 'The identification of such a large mineralized area at this early stage in our drill programme is an exciting result. Our objective is the identification of an economically viable uranium resource in Niger and we look forward to informing shareholders regarding the ongoing work programme as soon as results are made available.' A 10,000 metre drilling programme commenced in January 2008 and to date 4,100 metres have been completed. Drilling has focused on target 17 where a mineralized layer 900 metres wide, with a minimum strike length of 5,000 metres and potential for significant extension in a westerly direction, has been identified. Niger Uranium plans to complete several step-out fence lines to extend the currently delineated mineralized area. At target 17, the uranium is hosted in proximity to the contact between oxidized sandstones of the Tegama Formation and reducing mudstones of the Irhazer Formation, within the Tim Mersoi Basin. The proximity to surface, continuity of the mineralization and gentle dip (between 2 and 5 degrees to the southwest) support in-situ leaching or open-pit mining as a potential extraction technique. Visual observation of material exposed in trenches suggests that carnotite is the dominant uranium mineral occurring as growths and coatings on fracture surfaces. 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 eU3O8. To support the probe data, borehole samples were sent to SGS Lakefield for XRF analysis for U3O8. The XRF results are contained in appendix 2. Samples were all one metre in length and taken at mineralized intervals as indicated by the probe data. The XRF U3O8 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 probing. If this is verified by additional drilling and sampling, a significant increase of grades reported in appendix 1 can be expected. To advance the other targets within the In Gall and Irhazer Licenses, the company will commence drilling late in April 2008 to follow up on surface grab samples which returned up to 0.98 % U3O8, as reported on 29 January 2008. At target 10, a ground magnetic survey was completed to assist with the positioning of 4 step-out holes along strike and down dip of AB003 which intersected 9.2 metres grading 105 ppm eU3O8 from 190.9 metres depth, as indicated by radiometric probing. At other targets a survey using 1500 CR39 radon detectors will help define drill targets along major structures identified from satellite and airborne radiometric data. The CR39 film detects radon emanating from concealed uranium mineralization. Appendix 1 Results for all boreholes within the mineralized area at target 17 as determined by radiometric probing.

Explosive or hydraulic fracturing may be used to create open pathways in the deposit for a solution to penetrate. Leaching solution is pumped into the deposit where it makes contact with the ore. The solution bearing the dissolved ore content is then pumped to the surface and processed. Tri-cone A rapid, relatively cost effective technique of drilling boreholes for drilling uranium exploration by gamma ray probe. The tri-cone drill (or roller) bit, consists of three cone shaped toothed rollers in a cluster. Each of the cones has hard teeth mounted on bearings. The spatial control of sampling for laboratory purposes is not good with tri-cone drilling and alternative drilling techniques would have to be used. CR39 Is a technique of soil survey to measure or detect buried uranium radon mineralization in certain geological environments. survey U3O8 The uranium content of a sample is reported as U3O8 if the analysis is performed in a laboratory. Uranium content when measured by a gamma ray down hole probe is reported as eU3O8. eU3O8 XRF X-ray Fluorescence Analysis is a sophisticated laboratory technique for the analysis of uranium and other elements BHID Abbreviation for borehole identification number.
