“Northwestern Mineral Ventures Inc. (TSX-V: NWT; OTCBB: NWTMF) is pleased to report results from above-limit rock chip samples, which were collected from outcrops on its Niger uranium properties.  The samples were submitted for re-analysis after they exceeded the detection limits of uranium tests routinely used to analyze samples from Niger.  Further analysis of these above-limit samples reveals uranium values of up to 1.0% U3O8.


“We are extremely excited by these high-grade uranium levels, which are widely distributed and likely part of a larger mineralized system.  Not only are they the highest values discovered on our Niger properties to date, they further validate our belief that In Gall and Irhazer host the structures commonly associated with uranium deposits in Niger,” said Marek J. Kreczmer, President and CEO of Northwestern.  “It is also important to note that producing mines and deposits in Niger typically grade from 0.1% to 0.42%.  We are scheduling an aggressive expansion of our exploration efforts and look forward to revealing the full potential of our concessions in Niger.”


Results


Northwestern has confirmed that its 100%-owned uranium properties in Niger host high-grade uranium mineralization of up to 1.0% U3O8.  Details of the five samples submitted for re-analysis, which returned results ranging from 0.22% to 1.0% U3O8, are provided in the table below:

The samples were collected from outcrops during a first-pass reconnaissance exploration of airborne anomalies covering a large area on Northwestern’s In Gall and Irhazer uranium concessions in Niger.


In Gall and Irhazer cover 988,000 acres (4,000 square kilometers) of highly prospective land within the same stratigraphy as two operating uranium mines that together provide almost 10% of worldwide production.  Niger currently ranks as one of the world’s top producers of uranium.


Quality Assurance

Fieldwork in Niger is being conducted under the supervision of Abdelkarim Aksar, P.Geo., Northwestern’s Niger Project Manager.  Laboratory analysis was conducted by SGS Lakefield Research Africa by Aqua Regia Digest followed by ICP-OES.  Analysis of all samples is carried out using Standard Reference Materials and a minimum of 10% of samples are analyzed in duplicate.  







Re-analysis was conducted by SGS using borat fusion followed by x-ray fluorescence.  Northwestern and SGS both maintain comprehensive and independent Quality Control/Quality Assurance programs.”
