‘‘Northwestern Mineral Ventures Inc. (TSXV: NWT; OTCBB: NWTMF) is pleased to announce the signing of a drilling contract with ESAFOR of Arlit, Niger. Drilling on Northwestern’s land is scheduled to commence in April after the equipment arrives in Niger and local crews have completed preparations.

‘‘This development is a significant milestone for Northwestern as we expect to be the first North American explorer since the 1970s to conduct a uranium drill program in Niger,’’ said Marek J. Kreczmer, President and CEO of Northwestern. ‘‘In light of recent increases in the price of uranium, which is currently selling for approximately US$90 per pound, we plan to continue aggressively advancing the discoveries made on our Niger land portfolio.’’

ESAFOR will provide a minimum of 2,000 meters of RC diamond core drilling during this first phase, with at least 20 holes planned to test mineralization at shallow depths. The program will initially target the anomaly that has returned uranium values approaching 0.1% U₃O₈ from surface grab samples. These are the highest uranium results recorded to date, as reported in a press release dated March 1, 2007. Producing mines and deposits in Niger typically grade from 0.1% to 0.42% U₃O₈.

While drilling is underway, Northwestern’s reconnaissance geological team will examine other areas of known mineralization and significant targets will be scheduled for drilling.

ESAFOR is one of the major drilling companies involved in uranium exploration and exploitation in Niger.

Quality Assurance

Fieldwork in Niger is being conducted under the supervision of Abdelkarim Aksar, P.Geo., Northwestern’s Niger Project Manager.

Samples selected for analysis will be sent to SGS Lakefield Research Africa in Johannesburg, South Africa. This laboratory uses industry-standard methods and ISO / IEC 17025 quality assurance and quality control practices. Northwestern and SGS maintain comprehensive and independent Quality Control/Quality Assurance programs.’’
