This Form 6-K consists of:

"Northwestern Mineral Ventures Inc. (TSX-V: NWT; OTCBB: NWTMF) is pleased to
announce the completion of a Formal Agreement to acquire 100% ownership of the
Firefly Project in Utah's La Sal uranium district. The property includes two
past-producing uranium-vanadium mines, which could be reactivated and economic
once more given the current 24-year high in the price of uranium. Firefly also
includes additional areas designated by the US Geological Survey as "favorable"
for uranium mineralization.

"This acquisition reiterates our commitment to adding high-quality properties to
our growing land portfolio, which already contains significant potential for
uranium mineralization," said Kabir Ahmed, Chairman and CEO of Northwestern.
"Given the current strength in the price of both uranium and vanadium, we will
be pursuing a strategic objective of bringing our Firefly mine back into
production, subject to completing an engineering review and obtaining necessary
permits. We are in the process of dispatching a geologist to the mine to further
assess existing infrastructure and other pre-production requirements."

The Firefly Project contains 39 mineral claims covering 315 hectares (780 acres)
and includes the past producing Firefly and Gray Daun Mines. The claims have a
stratigraphy that is typical of the Colorado Plateau style, one of the principal
sources of uranium in the United States. Situated approximately 370 kilometers
(230 miles) southeast of Salt Lake City, Firefly is widely accessible via a
network of drill access roads and a power line runs past the main adit to the
Firefly Mine, where 365 meters (1,200 feet) of mine workings remain. There is
also a uranium-vanadium processing plant 160 kilometers (100 miles) south of the
property.

Mining began at Firefly in 1953 and continued for more than 25 years, as
reported in a press release dated September 29, 2005. Production was halted when
operations were no longer economic owing to world uranium prices at that time.
The current global interest in nuclear power has resulted in a substantial
increase in the price of uranium, which could make these deposits economically
viable once more. The ore produced at the mine contained 0.35% U3O8 (uranium
oxide) and 2.04% V2O5 (vanadium oxide).

For details of the Formal Agreement, please refer to the Company's press release
dated September 29, 2005, and the Bulletin issued by the TSX Venture Exchange on
October 5, 2005 approving the acquisition."

Registrant has duly caused this report to be signed on its behalf by the
undersigned, thereunto duly authorized.
