PRESS RELEASE

                     IUC ANNOUNCES 43-101 RESOURCE ESTIMATE
                         ON ITS HENRY MOUNTAINS COMPLEX

VANCOUVER, BC... OCTOBER 16, 2006 (IUC:TSX)... INTERNATIONAL URANIUM CORPORATION
("IUC" or the "Company") is pleased to announce that an independent technical
report compliant with NI 43-101 has been prepared on the Henry Mountains Complex
located in southeastern Utah. Henry Mountains is one of several uranium mining
projects the Company is moving towards production. Henry Mountains is comprised
of the Bullfrog and Tony M deposits. The Tony M deposit area includes full mine
infrastructure. Following the discovery of the Tony M deposit in 1977, nearly 20
miles of mine workings were developed. The mine is accessed via two parallel
declines extending over 10,000 ft. into the deposit. The nearby Bullfrog
resources can be accessed via the Tony M infrastructure. This long life mining
operation is expected to commence production in early 2007 subject to receipt of
the necessary permits.

 DEPOSIT    CATEGORY     TONS    EU(3)O(8)     (MILLION POUNDS)
--------   ---------   -------   ---------   -------------------
                                 
Bullfrog   Indicated     1.06      0.324             6.87
Bullfrog   Inferred      0.88      0.345             6.05


Notes: The Bullfrog mineral resource estimate complies with the requirements of
       National Instrument 43-101 and the classification complies with CIM
       definition standards.

       The cut-off criteria are 0.20% eU(3)O(8) and minimum GT (grade times
       thickness) of 0.8 ft.% eU(3)O(8).

       The term eU(3)O(8) refers to equivalent U(3)O(8) grade derived by gamma
       logging of drill holes.

Tony M    Indicated     1.28       0.21             5.3


Notes: The mineral resource estimate does not comply with the requirements of
       National Instrument 43-101. In the opinion of Scott Wilson RPA, the Tony
       M historical mineral resource is the most reasonable and reliable of
       several historical estimates, and the classification complies with CIM
       definition standards.

       The cut-off grade is 0.15% eU(3)O(8).

       The term eU(3)O(8) refers to equivalent U(3)O(8) grade derived by gamma
       logging of drill holes.

The Tony M and Bullfrog deposits form two more or less continuous elongate
zones. The mineralization consists of Salt Wash-type tabular (vanadium)-uranium
sandstone deposits hosted by the Salt Wash Member of the Upper Jurassic Morrison
Formation. IUC's Henry Mountain deposits occur within the lowermost one hundred
feet of the 500 ft. thick Salt Wash Member. Uranium mineralization consists
primarily of coffinite, accompanied by vanadium minerals consisting primarily of
the oxide montroseite and vanadium chlorite. In the oxidized zone above the
water table in the southern part of the mine, the uranium and vanadium occur in
a series of hydrous potassium and calcium uranium-vanadium minerals, together
with montroseite.



Scott Wilson RPA notes that there is potential to add to the Bullfrog uranium
resources by drilling holes to offset high-grade intercepts in areas where only
wide spaced drilling has been done in the past. Scott Wilson RPA's full report
prepared by Thomas C. Pool, P.E., a Qualified Person pursuant to NI 43-101, is
available on Sedar (www.sedar.com). Mr. Pool has reviewed the technical contents
related to resource estimate of the Henry Mountains Complex contained in this
release.

As recently announced, IUC and Denison Mines Inc. are proposing to merge the two
companies to create a new diversified and growth-oriented uranium producer. The
new company will be the only intermediate uranium producer in North America,
with production rapidly reaching over 5.5 million lbs of U(3)O(8) by 2010.
Combined assets include:

     -    Growing uranium production profile

     -    5 active uranium mining projects (3 in the US; 2 in Canada)

     -    Interest in 2 of the 4 licensed and operating uranium mills in North
          America

     -    Global portfolio of world-class exploration projects

     -    Combined working capital > $130 million, and no debt

The proposed merger is subject to all requisite regulatory approvals. A full
information circular regarding the merger will be mailed to shareholders in
mid-October.

Ron Hochstein, President of IUC, commented, "The Henry Mountains Complex is but
one of several key uranium assets the Company holds in the U.S. which also
includes the 100% owned White Mesa uranium mill. With the upcoming proposed
merger with Denison and the resulting combination of assets, the new company
will have a diversified and immediate uranium production base, the commanding
uranium licensed mill capacity in North America and a wide breadth of global
exploration projects with a large experienced team."

IUC is engaged in uranium exploration and production. It holds significant
uranium deposits in Mongolia and uranium and vanadium deposits in the U.S. and a
fully permitted 2,000 ton per day uranium/vanadium mill near Blanding, Utah (one
of only two operating uranium mills in the U.S.), as well as uranium exploration
properties in the Athabasca Region in Canada. The Company also processes and
recycles uranium-bearing waste materials as an environmentally superior
alternative to direct disposal. In addition, the Company is a significant
shareholder in Fortress Minerals Corp., a public company engaged in precious and
base metal exploration in Russia, Nicaragua and Mongolia.

Statements contained in this news release which are not historical facts are
forward-looking statements that involve risks, uncertainties and other factors
that could cause actual results to differ materially from those expressed or
implied by such forward-looking statements. Factors that could cause such
differences, without limiting the generality of the following, include: risks
inherent in exploration activities; volatility and sensitivity to market prices
for uranium and vanadium; the impact of the sales volume of uranium and
vanadium; competition; reliance on income from processing uranium-bearing waste
materials; the impact of change in foreign currency exchange rates and interest
rates; imprecision in resource and reserve estimates; environmental and safety
risks including increased regulatory burdens; changes to reclamation
requirements; unexpected geological or hydrological conditions; political risks
arising from operating in certain developing countries; a possible deterioration
in political support for nuclear energy; changes in government regulations and
policies, including trade laws and policies; demand for nuclear power;
replacement of production and failure to obtain necessary permits and approvals
from government authorities; weather and other natural phenomena; ability to
maintain and further improve positive labour relations; operating performance of
the facilities; success of planned development projects; and other development
and operating risks. Although IUC believes that the assumptions inherent in the
forward-looking statements are reasonable, undue reliance should not be placed
on these statements, which only apply as of the date of this release. IUC
disclaims any intention or obligation to update or revise any forward-looking
statement, whether as a result of new information, future events or otherwise.

United States investors are advised that while the term resources is recognized
by Canadian regulations, SEC does not recognize that term. Investors are
cautioned not to assume that all or any part of mineral deposits in this
category will ever be converted into reserves.



*    Uranium resources for the three mineralized zones on the Bullfrog property
     have been estimated several times in the past. The latest historical
     estimate was by Energy Fuels Nuclear (EFN) in 1993. Scott Wilson RPA has
     audited the 1993 EFN Bullfrog mineral resource estimate and has accepted it
     as a current mineral resource. The estimate is based on a minimum cut-off
     of 0.2% U(3)O(8) at 0.8 ft.% GT and does not include any intervals with
     less than a 0.5 ft. intercept of 0.08% U(3)O(8). The estimate is based on
     gamma logs from 1,801 rotary drill holes. A total of 81 core holes were
     drilled to recover samples for chemical and geologic analysis and to
     establish stratigraphic relationships.

**   In 1989, Nuclear Assurance Corporation (NAC) prepared estimates for the
     Tony M deposit using the January 1985 estimate of mineable resources by
     Pincock, Allan and Holt, Inc. (PAH). The PAH estimate was based on the
     results of gamma logging of surface drill holes. The 1989 NAC estimate is
     1.3 million tons at an average grade of 0.21% U(3)O(8), containing 5.3
     million pounds U(3)O(8) based on a cut-off of 0.15% U(3)O(8) and a GT
     cut-off of 0.3 ft.%. Scott Wilson RPA is of the opinion that NAC's estimate
     for the Tony M deposit, at a cut-off of 0.15%, was reliable at the time,
     met industry standards, is the most relevant historical estimate today, and
     meets the CIM classification of an Indicated Mineral Resource.
