Joint Venture Property Portfolio

Northwestern and UraMin are contributing to the Joint Venture Company a total of
eight uranium properties -- known as Irhazer, In Gall, Kamas 1 to 4, and Dabala
3 and 4 -- covering a total of 1,673,644 acres (6,773 square kilometers).

Irhazer and In Gall have returned uranium values ranging from 0.22% U3O8 to 1.0%
U3O8 from five surface rock samples collected from outcrops, as reported in a
Northwestern Mineral Ventures press release on May 29, 2007, available on SEDAR
at www.sedar.com.  These samples were submitted for re-analysis after they
exceeded the detection limits of uranium tests routinely used to analyze samples
from Niger.  Producing mines and deposits in Niger typically grade from 0.1% to
0.42% U3O8, with the highest grades being mined at greater depths.

Kamas 1 to 4 and Dabala 3 and 4 are adjacent and situated along the proven Arlit
fault, north of a successful uranium-producing mine.

This news release includes certain "forward-looking statements" within the
meaning of the United States Private Securities Litigation Reform Act of 1995.
Without limitation, statements regarding potential mineralization and resources,
exploration results, and future plans and objectives of each of Northwestern,
UraMin and the Niger Company (collectively, the "Companies") are forward looking
statements that involve various degrees of risk.  The following are important
factors that could cause the Companies' actual results to differ materially from
those expressed or implied by such forward looking statements: changes in the
worldwide price of mineral commodities, general market conditions, risks
inherent in mineral exploration, risks associated with development, construction
and mining operations, the uncertainty of future profitability and the
uncertainty of access to additional capital.

Potential quantity and grade is conceptual in nature, there has been
insufficient exploration to define a mineral resource on any of the properties
referenced in this press release and it is uncertain if further exploration will
result in any such targets being delineated as a mineral resource.  The
