   NORTHWESTERN AND URAMIN PROVIDE UPDATE ON DRILL PROGRAM UNDERWAY IN NIGER


Toronto - June 27, 2007 - Following their successful agreement to form a Joint
Venture Company in Niger, Northwestern Mineral Ventures Inc. (TSX-V: NWT; OTCBB:
NWTMF) and UraMin Inc. (TSX: UMN; AIM: UMN) commenced drilling on the highly
prospective Irhazer and In Gall concessions.  The phase one program is scheduled
to include a total of 6,562 feet (2,000 meters) of mud rotary drilling to be
completed prior to the start of the rainy season in Niger.  The drill program is
focusing on high-priority areas near radioactive structural domes that were
discovered during earlier ground exploration.

"This drill phase marks the beginning of a major, expanded exploration program
on our sizeable Niger property portfolio and we are pleased to have rapidly
commenced drilling at Irhazer and In Gall," said Marek J. Kreczmer, President
and CEO of Northwestern and Managing Director and CEO of the Joint Venture
Company.  "Irhazer and In Gall have so far returned high-grade uranium values of
up to 1.0% U3O8 from widely spaced rock chip samples.  We look forward to
revealing the full potential of our Niger concessions."

Ian Stalker, Executive Deputy Chairman of the Joint Venture Company, said, "The
rapid progress made so far highlights our commitment to the development of our
activities in Niger and we look forward to updating the market as soon as is
practicable as to the results of this exploration drilling. Work on the UraMin
properties in Niger, which forms part of the new JV Company, has also commenced
on the ground."

Sites being tested in this initial phase of drilling include a total of three
targets at Irhazer and In Gall.  The aim of the program is to test in the
vicinity of radioactive structural domes, buried sandstone units known for
hosting economic mineralization at the nearby Azelik and Imouraren ore bodies.

Drilling is being conducted by ESAFOR of Arlit, Niger.  ESAFOR is one of the
major drilling companies involved in uranium exploration and exploitation in
Niger.  At least 14 holes are planned to test areas with potential uranium
mineralization at shallow depths during this first phase of drilling.


Joint Venture Property Portfolio

The Joint Venture Company boasts 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.  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.

The formation of the new corporation and completion of the transactions are
subject to review and approval in the Republic of Niger, as well as the receipt
of all applicable regulatory approvals (including the approval of the TSX
Venture Exchange) and a favorable fairness opinion.


ABOUT NORTHWESTERN:

Northwestern Mineral Ventures (www.northwestmineral.com) is an international
resource exploration company with an experienced management team.  The company
is focused on properties in Niger and Canada with potential uranium targets.
Northwestern also has a precious and base metal property in Mexico.
Northwestern is listed on the NASD Bulletin Board under the symbol "NWTMF" and
the TSX Venture Exchange under the symbol "NWT."


ABOUT URAMIN:

UraMin (www.uramin.com) was established in 2005 to acquire and develop mineral
properties, predominantly uranium. UraMin is focused on advancing its 100%-owned
Trekkopje uranium project in Namibia to the completed Definitive Feasibility
Study stage. A trial mine is planned for the fourth quarter of 2007 and
commercial production is planned for late 2008.  The Company also has a
feasibility study underway at its 90%-owned Bakouma uranium project in the
Central African Republic and on its 74%-owned Ryst Kuil uranium project in South
Africa. SRK is the lead consultant for the Ryst Kuil Project.

UraMin intends to bring these near-surface open-pitable projects into
production, utilizing efficient mining and processing methods currently in
practice worldwide in similar deposits in a cost-effective manner.

UraMin also has a number of exploration projects in both Africa (Chad, Niger,
Senegal and Mozambique) and joint venture projects in Canada (the Rea Project
within the Athabasca Basin in Alberta and the Labrador Project in Quebec) on
which it is advancing exploration programs that could provide a pipeline of
potentially economic uranium projects for the future.

Mr. G M Greenway, Pr.Sci.Nat (SACNASP), MSAIMM, MGSSA, is the qualified person
responsible for the current exploration program in Niger and has verified the
data reported above. Mr. Greenway is a consultant to UraMin, and has sufficient
experience relevant to the style of mineralisation and type of deposits under

Without limitation, statements regarding potential mineralization and resources,
exploration results, and future plans and objectives of the Company are forward
looking statements that involve various degrees of risk.  The following are
important factors that could cause the Company's actual results to differ

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
