"Northwestern Mineral Ventures Inc. (TSX-V: NWT; OTCBB: NWTMF) is pleased to
announce the filing of its 43-101 report for the Picachos property with
securities commissions and on SEDAR. The Picachos property is located in Durango
State, Mexico.

Prepared by Watts, Griffis and McOuat Limited ("WGM") of Toronto, the report
states that "based on its comparisons with other mines and mineral deposits in
the Sierra Madre, including the Tayoltita Mine located a short distance to the
north, WGM is of the opinion that the Picachos area has the potential to host an
economically significant silver-gold deposit."

The report further states that "the Picachos structure appears to be the only
caldera in the belt which lacks a major operating mine, a fact WGM ascribes to a
general lack of persistent and systematic exploration, rather than geological
factors."

A total of 10 bedrock samples were collected by WGM to provide independent data
on the characterization of the mineralization at Picachos. The samples were sent
for analysis to the SGS Laboratory in Don Mills (Toronto), a full service
mineral laboratory with ISO 9002 accreditation. The 10 samples ranged in gold
values from 0.03 to 17.46 g/t Au. Excluding the two very lowest values (each
measuring 0.03 g/t Au), the report states that "gold contents in the remainder
of the sample population were generally high enough to be of direct economic
interest (3.13 g/t to 17.46 g/t), or were sufficiently high to have an economic
impact on the value of the rock (0.39 g/t to 2.78 g/t)." Sampling by WGM also
returned silver values of economic interest in five of 10 samples with silver
grades ranging from 554 g/t to 1,313 g/t.

Based on recommendations in the 43-101 report, the work program at Picachos will
consist of geophysical and geochemical surveys and analysis. The program has an
estimated total budget of CDN $526,000, which is fully funded with cash on hand.
The program is expected to begin in the new year.

"Northwestern looks forward to further exploring the Picachos property," said
Kabir Ahmed, President and CEO of Northwestern. "Our ultimate goal is the
development of a mine or mines on the property to fully exploit the underlying
mineral concessions."

Picachos is comprised of 16,556 acres (6,700 hectares) or 67 square kilometers
and is located in Durango State, Mexico. Several sites on the property indicate
historic mining operations, including El Toro and Los Cochis with Spanish mine
workings, and El Pino, which was the site of a former small producing mine.

Northwestern is earning its 50% interest in the Picachos property through its
agreement with RNC Gold Inc. (TSX: RNC). This agreement requires Northwestern to
expend CDN $500,000 in the first year and CDN $1 million in year two on
exploration and development. Northwestern is also required to generate a
positive feasibility study, which provides for the production of a minimum of
25,000 ounces of gold per year.

The 43-101 report, entitled "A Technical Review of the Picachos Silver-Gold and
Base Metals Prospects, Western Durango State, Mexico," is dated November 24,
2004. It was prepared by Al Workman, P.Geo., Senior Geologist and Vice-President
of WGM, and a qualified person as defined by National Instrument 43-101. Please
refer to the 43-101 Report on SEDAR for further information on the Picachos
property. All of the disclosure in this press release is based upon the
aforementioned 43-101 report, and the information contained herein was reviewed
by Al Workman. Discussion of potential quantity and grade is conceptual in
nature as there has been insufficient exploration to define a mineral resource
on the property. It is uncertain if further exploration will result in discovery
of a mineral resource on the property."
