‘‘Northwestern Mineral Ventures Inc. (TSXV: NWT; OTCBB: NWTMF) is pleased to announce initial assay results from rock samples collected during a first-pass reconnaissance program on its 100%-owned uranium properties in Niger. The results confirm uranium mineralization associated with several of the anomalies identified during an earlier airborne survey.

‘‘We are extremely excited that ongoing exploration work has confirmed the presence of uranium on our Niger properties,’’ said Marek J. Kreczmer, President and CEO of Northwestern. ‘‘These initial rock sample results further validate our belief that In Gall and Irhazer host the structures and sedimentary units that commonly host uranium deposits in Niger. We look forward to commencing a drill program in the spring to further test these and other targets.’’

Initial Results

Assay results from 61 surface grab samples, collected during a brief reconnaissance exploration of airborne anomalies, reveal uranium values of almost 0.1% U₃O₈ (AZX_100). Details of the 13 assays that returned values above 0.03% U₃O₈ are provided in the table below.

‘‘These uranium values are significant because surface assay levels can be impacted by weathering oxidation in desert environments, which can cause surface uranium depletion. As such, the extent of the uranium grades on our properties has yet to be fully revealed,’’ adds Mr. Kreczmer.

Producing mines and deposits in Niger typically grade from 0.1% to 0.42% U₃O₈, with the highest grades being mined at greater depths.

RSG Global is currently conducting a systematic evaluation of 17 top-ranked near-surface uranium anomalies, which are on trend with known uranium deposits and occurrences. Areas are being evaluated in order of priority, with revisions made in the field based on results of the reconnaissance program. Rock samples were collected during a first-pass reconnaissance program, which was initiated in November 2006. Additional results from ongoing exploration work will be announced as they are received.

Uranium Deposits in Niger

According to the World Nuclear Association, Niger is one of the world’s top uranium producers with all of its uranium currently being produced from two mines that are operated by Areva (Cogema). The Somaïr mine in Arlit and Cominak in Akouta together produced 3,093 metric tonnes of uranium in 2005, accounting for almost 10% of annual global production. Somaïr is an open pit mine that, since 1971, has produced more than 40,000 metric tonnes of uranium at an average assay of 2 kg of uranium

oxide per ton of ore, (approximately 0.2% U₃O₈). Cominak has produced over 48,000 metric tonnes from underground mines, with the average grade ranging from 4.5 to 5 kg of uranium oxide per metric ton of ore (approximately 0.45-0.5% U₃O₈).

Located within the same stratigraphy as Somair and Cominak, Northwestern’s Irhazer and In Gall concessions were selected for their favorable geology and exploration potential. Each concession is 494,000 acres (200,000 hectares) in size, representing a total land position of 988,000 acres (400,000 hectares).

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 based out of South Africa by Aqua Regia Digest followed by ICP-OES.’’
