PRESS RELEASE

                DENISON TO COMMENCE TRADING UNDER SYMBOL "DML" AT
                       MARKET OPENING ON DECEMBER 7, 2006

TORONTO, ON -- DECEMBER 7, 2006 -- DENISON MINES CORP. ("Denison" or the
"Company") (IUC:TSX, DEN:TSX) is pleased to announce that the Company will
commence trading as Denison Mines Corp. ("New Denison") on the Toronto Stock
Exchange under the symbol "DML" effective today, at the market opening on
December 7, 2006. The new CUSIP number of the common shares will be 248356107
and the ISIN number will be CA 2483561072.

Denison Mines Corp. is the result of a recent merger between International
Uranium Corporation ("IUC") and Denison Mines Inc. ("Old Denison"). Each common
share of Old Denison has now become 2.88 common shares of IUC and IUC has
changed its name to Denison Mines Corp.

Also as a result of the merger, the terms of the two series of Old Denison
common share purchase warrants have been amended, effective December 1, 2006, as
follows: (1) each New Denison common share purchase warrant that will trade
under the symbol DML.WT will entitle the holder to acquire 2.88 common shares of
New Denison at $15.00 per warrant until November 24, 2009 (CUSIP 248356115, ISIN
CA 2483561155); and (2) each New Denison common share purchase warrant that will
trade under the symbol: DML.WT.A will entitle the holder to acquire 2.88 common
shares of New Denison at $30.00 per warrant until March 1, 2011 (CUSIP
248356123, ISIN CA 2483561239). Fractional common shares of New Denison will not
be issued upon exercise of either series of warrants. In lieu thereof, a cash
payment will be made equal to the value of the right to acquire such fractional
interest.

Registered shareholders of the Old Denison are requested to submit a Letter of
Transmittal to facilitate conversion of their shares to New Denison. A Letter of
Transmittal has been mailed to all registered shareholders with instructions on
how to complete and submit the form. Shareholders whose Old Denison shares are
registered in the name of a broker, investment dealer, bank, trust company or
other nominee should contact that nominee for assistance in exchanging their Old
Denison shares for the New Denison shares.

The merger has created a growth oriented and diversified uranium producer with
currently estimated annual production of approximately 5 million pounds U(3)O(8)
by 2010 with a strong financial position of approximately Cdn$118 million
(September 30, 2006) in working capital and no debt.

Denison Mines Corp. is considered the premier intermediate uranium producer in
North America, with mining assets in the Athabasca Basin Region of Saskatchewan,
Canada and the southwest United States including Colorado, Utah, and Arizona.
Further, the Company has ownership interests in two of the four uranium mills
operating in North America today. The combination of a diversified mining asset
base with parallel ownership of milling infrastructure in highly politically
stable jurisdictions has uniquely positioned the Company for growth and
development into the future.

The Company also has a strong exploration portfolio with large land positions in
the United States, Canada and Mongolia. Correspondingly, the Company has one of
the largest uranium exploration teams among intermediate uranium companies.

the United States Private Securities Litigation Reform Act of 1995 and similar
Canadian legislation, concerning the business, operations and financial

and permitting, mining or processing issues; currency exchange rate

identified by the use of forward-looking terminology such as "plans", "expects"
or "does not expect", "is expected", "budget", "scheduled", "estimates",

achieved".

Forward looking statements are based on the opinions and estimates of management
as of the date such statements are made, and they are subject to known and
unknown risks, uncertainties and other factors that may cause the actual
results, level of activity, performance or achievements of Denison to be
materially different from those expressed or implied by such forward-looking
statements, including but not limited to risks related to: unexpected events
during construction, expansion and start-up; variations in ore grade, tonnes
mined, crushed or milled; delay or failure to receive board or government
approvals; timing and availability of external financing on acceptable terms;
risks related to international operations; actual results of current exploration

management of Denison has attempted to identify important factors that could
cause actual results to differ materially from those contained in

be as anticipated, estimated or intended.

actual results and future events could differ materially from those anticipated
in such statements. Accordingly, readers should not place undue reliance on
forward-looking statements. Denison does not undertake to update any
forward-looking statements that are incorporated by reference herein, except in
accordance with applicable securities laws. Mineral resources, which are not
mineral reserves, do not have demonstrated economic viability. Readers should

year ended December 31, 2005, and other continuous disclosure documents filed by
each of them since January 1, 2006 available at www.sedar.com, for further

CAUTIONARY NOTE TO UNITED STATES INVESTORS CONCERNING ESTIMATES OF MEASURED,
INDICATED AND INFERRED RESOURCES: This news release uses the terms "Measured",
"Indicated" and "Inferred" Resources. United States investors are advised that
while such terms are recognized and required by Canadian regulations, the United
States Securities and Exchange Commission does not recognize them. "Inferred

as to their economic and legal feasibility. It cannot be assumed that all or any
part of an Inferred Mineral Resource will ever be upgraded to a higher category.
Under Canadian rules, estimates of Inferred Mineral Resources may not form the
basis of feasibility or other economic studies. UNITED STATES INVESTORS ARE
CAUTIONED NOT TO ASSUME THAT ALL OR ANY PART OF MEASURED OR INDICATED MINERAL
RESOURCES WILL EVER BE CONVERTED INTO MINERAL RESERVES. UNITED STATES INVESTORS
ARE ALSO CAUTIONED NOT TO ASSUME THAT ALL OR ANY PART OF AN INFERRED MINERAL
RESOURCE EXISTS, OR IS ECONOMICALLY OR LEGALLY MINEABLE.
