Chief Executive Officer’s Letter

23 January 2007

Dear OmegaCorp Shareholder

Denison is pleased to provide to you its Offer to acquire all your shares in OmegaCorp for a price of $1.10 per share.

Reasons to Accept

The Offer values OmegaCorp at approximately $170 million. The Offer represents:

| • | an approximate 25% premium to the volume weighted average price of OmegaCorp Shares over the
previous 20 trading days before 5 December 2006 (the date the bid was announced by Denison); |
| --- | --- |
| • | a substantial premium to the price of OmegaCorp Shares over the following periods: |

•	a premium of 100% to the 1 year volume weighted average OmegaCorp Share price of $0.55;
•	a premium of 175% to the 2 year volume weighted average OmegaCorp Share price of $0.40; and
•	a premium of 424% to the 1 year OmegaCorp Share price low of $0.21;

•	an opportunity for OmegaCorp Shareholders to immediately realise the benefits from the Kariba Project;
•	the assumption by Denison of the substantial investment risks associated with an investment in
OmegaCorp including, but not limited to, permitting, resource upgrading, operational, metallurgical
and financial risks involved in the development and commercialisation of the Kariba Project;
•	an offer that has been unanimously recommended by the directors of OmegaCorp in the absence of a
superior offer;
•	an offer that the directors of OmegaCorp have announced their intention to accept in respect of
their own shareholdings in the absence of a superior offer; and
•	a cash offer.

OmegaCorp Shareholders should be aware that the OmegaCorp Share price may decline below current levels, at least in the short term, if the Offer lapses and no competing bid emerges.

Denison’s Offer is conditional upon certain conditions. Details of the conditions are set out in section 9.8 of the Bidder’s Statement.

This is an important document which you should retain throughout the Offer Period.

Folio 1 /Folio

PAGEBREAK

We believe that the Offer is very fair in all circumstances. We encourage you to accept the Offer as soon as possible. Please read this document carefully. The Offer is open for your acceptance until 5pm CST on 28 February 2007 unless extended. To accept the Offer, complete and return the enclosed Acceptance Form or instruct your broker to initiate acceptance of the Offer through CHESS.

If you have any questions about the Offer, please contact the offer enquiry line on 1300 653 890 (or +61 3 9415 4213 for international callers) or your stockbroker, legal or financial adviser.

Yours sincerely

Chief Executive Officer / Director

Folio 2 /Folio

Why you should accept the Offer

1.
The Offer represents an attractive premium over the historical market price of OmegaCorp
Shares. The Offer at $1.10 per OmegaCorp Share represents a premium of approximately:

| • | 25% to the volume weighted average price of OmegaCorp Shares over the 20 trading
days before the Announcement Date (being 5 December 2006); |
| --- | --- |
| • | 100% to the 1 year volume weighted average OmegaCorp Share price of $0.55; |
| • | 175% to the 2 year volume weighted average OmegaCorp Share price of $0.40; and |
| • | 424% to the 1 year OmegaCorp Share price low of $0.21. |

While as of 22 January 2007 (being the day before the date of this Bidder’s Statement) OmegaCorp Shares were trading at prices slightly above the Offer Price, Denison believes that this is a reaction to Denison’s takeover announcement.

If the Offer does not proceed, and no competing bid emerges, the current OmegaCorp share price may not be sustainable and is likely to fall below the Offer Price.

If you accept the Offer and it becomes unconditional, you will receive cash of $1.10 for each of your OmegaCorp Shares. Further, you will not pay any brokerage or stamp duty if you accept the Offer. You may incur brokerage costs and GST on those costs if you choose to sell your OmegaCorp Shares on ASX.

Folio 3 /Folio

PAGEBREAK

| 2. |
| --- |
| OmegaCorp’s Kariba Project is at an early stage of development and the resource is a 100%
JORC inferred resource. It should be noted that inferred resources under JORC are the lowest
confidence category of resource classification and a significant amount of work needs to be
undertaken to determine the commercial viability, if any, of the Kariba Project. Accordingly,
it may be 2 years or a number of years before commercial operations on the Kariba Project
commence, if at all. |
| Successful development and commercialisation of the Kariba Project will require a combination
of a number of things: |

| • | a successful exploration and development program to upgrade the resource to a higher confidence
classification and determine the commercial viability of the Kariba Project; |
| --- | --- |
| • | a strong and capable management team with the appropriate mix of specific skills — from
geology, mining, metallurgy, engineering and construction through to project financing and
marketing of the product; |
| • | a significant amount of capital; and |
| • | regulatory approvals. |

| At this time, the government of Zambia has yet to issue any licence for mining uranium in Zambia.
The Zambian Government has publicly stated that prior to granting of uranium mining licenses the
Zambian Government will need to implement the International Atomic Energy Agency guidelines, which
will establish health and environmental policies for uranium mines. |
| --- |
| Denison is better able to provide the financing required for the Kariba Project. |
| Denison possesses a diversified mix of uranium production assets with varying cost profiles. The
Kariba Project is likely to occupy the higher-cost end of Denison’s portfolio. Therefore, Denison
is potentially better able to absorb future uranium price volatility than a single project company
such as OmegaCorp. |

| 3. |
| --- |
| This Offer allows OmegaCorp Shareholders to eliminate the risk associated with future
funding uncertainties in exchange for a cash payment. |
| Given the early stage of development of OmegaCorp’s Kariba Project, OmegaCorp will require a
significant amount of capital to advance this project to eventual production. Current
estimates from OmegaCorp’s preliminary Scoping Study announced on 13 November 2006, estimated
the capital cost at approximately $60 million (US dollars) which is several multiples of
OmegaCorp’s cash balance of approximately $11.7 million (as disclosed in OmegaCorp’s
announcement on 31 October 2006). |
| Failure to secure appropriate funding on a timely basis may cause OmegaCorp to either
postpone, or cancel, its development plans. |
| Development of the Kariba Project will necessitate OmegaCorp entering into additional
financing or potential joint venture arrangements, the availability and terms of which are
uncertain and may not be favourable to OmegaCorp Shareholders. |

Folio 4 /Folio

PAGEBREAK

4.
In an ASX announcement dated 6 December 2006, OmegaCorp stated that:

| • | its directors unanimously recommend that OmegaCorp Shareholders accept the Offer and that
each director intends to accept the Offer in relation to their own shareholdings, in both
cases subject to there being no superior offer being made for OmegaCorp Shares; and |
| --- | --- |
| • | the directors believe that the Offer provides OmegaCorp Shareholders with the opportunity to
realise benefit from OmegaCorp’s wholly owned Kariba Project sooner than if OmegaCorp sought
to develop the Kariba Project itself. |

5.	The Offer is a 100% Cash Offer and OmegaCorp Shareholder’s Will Incur No Brokerage
	If OmegaCorp Shareholder’s accept the Offer and it becomes unconditional they will receive
$1.10 for each OmegaCorp Share. Further, no brokerage will be payable if the Offer is
accepted. OmegaCorp Shareholders may incur brokerage costs and GST on those costs, if they
choose to sell their OmegaCorp Shares on ASX.
6.	Retained entitlement in Mavuzi Project
	OmegaCorp has announced it proposes to spin off its Mavuzi Project through the IPO. Any
person who:

•	on the Relevant Date, is the registered holder of OmegaCorp Shares; or
•	is the registered holder of OmegaCorp Shares issued on exercise of OmegaCorp Options before the
end of the Offer Period;

| will have a priority entitlement to subscribe for securities under the IP0. |
| --- |
| In addition to the cash consideration OmegaCorp Shareholders will receive under this Offer, this
entitlement may provide additional value to OmegaCorp Shareholders. Three of OmegaCorp’s current
directors will manage the IPO. |

| 7. |
| --- |
| If OmegaCorp Shareholders do not accept the Offer and OmegaCorp remains a listed company,
there are risks and potential consequences that they should be aware of. These risks and
consequences have been detailed above and include, project development risks, risk of future
dilution, political and regulatory risks, and investment risks. |
| If Denison acquires more than 90% of the OmegaCorp Shares under the Offer it will be entitled
to compulsorily acquire the OmegaCorp Shares from OmegaCorp Shareholders who do not accept the
Offer. Under the compulsory acquisition provisions of the Corporations Act there is likely to
be a delay of up to six weeks for payment of the OmegaCorp Shares so acquired. |
| For the six months prior to the announcement of the Offer, OmegaCorp’s share price traded
between $0.51 and $1.03. While there are many factors that might influence the market price of
OmegaCorp Shares, there is a risk that, if the Offer lapses, the OmegaCorp Share price may
decline below current levels, at least in the short term. |
| No dividends have been paid by OmegaCorp to date. Given the capital requirements of the Kariba
Project there is no certainty of dividends or capital returns at any time for OmegaCorp
Shareholders. |
| Denison believes that the Offer is full and fair. |

1. Information about Denison

2.1 Introduction

Denison is Denison Mines Corp., a Canadian-listed uranium producer, developer and explorer. Denison is the result of a business combination between International Uranium Corporation (IUC) and Denison Mines Inc. (DMI) which concluded effective 1 December 2006 and under which the shares of DMI were converted into shares of IUC and IUC changed its name to Denison Mines Corp.

Denison is the premier North American intermediate uranium producer, with mining assets in the Athabasca Basin region of Saskatchewan, Canada, and the southwest United States including Colorado, Utah and Arizona. Further, Denison holds ownership interests in two of the four conventional uranium mills operating in North America today. The diversified mining asset base with parallel ownership of milling infrastructure in highly politically stable jurisdictions positions Denison for growth and development into the future.

2.2 Principal activities of Denison

Denison is a diversified and growth-oriented, intermediate uranium producer with an estimated annual production rate of approximately 5 million pounds of U 3 O 8 by 2010. Denison has a strong financial position with cash balances in excess of $180 million (Canadian dollars) and no debt (as of 15 January 2007).

Denison’s assets include an interest in two of the four licensed and operating conventional uranium mills in North America, with its 100% ownership of the White Mesa mill in Utah and its 22.5% joint venture ownership of the McClean Lake mill in Saskatchewan, Canada. The McClean Lake mill is the second largest conventional uranium mill in the world.

Both mills are fully permitted, operating and undergoing expansion. The share of the combined licensed annual milling capacity is expected to be 10.7 million pounds in 2007. Both the White Mesa and McClean Lake uranium facilities continue to meet or exceed all operational, environmental, safety and health targets. The McClean Lake facility was the first mining operation to obtain the internationally recognized ISO 14001 certification for environmental management systems.

In Canada, Denison owns a 22.5% interest in several uranium deposits through the McClean Lake Joint Venture. At the JEB, Sue A and Sue C deposits, the Joint Venture has mined and milled over 41 million pounds of uranium. Mining of the Sue E deposit is currently underway. The remaining known deposits, including McClean North, Sue B and Caribou, are expected to be mined over the next three years.

In the United States, Denison has a 100% interest in ten mines located in three separate mining areas. At four of the six mines located in the Colorado Plateau region, in the states of Utah and Colorado, Denison restarted mining operations in late 2006. Permitting of the Henry Mountains Complex, also in Utah, is underway and Denison anticipates receiving the permit in March 2007. Denison will begin mining operations upon receipt of the permit. Additionally, Denison owns three mines in the Arizona Strip mining region, located in Northeastern Arizona. Operations at the Arizona 1 Mine are expected to begin in late 2007. Permitting of the Pinenut and Canyon Mines will be completed in 2009-2010 and operations will begin once the permits are in place.

Denison enjoys a global portfolio of world-class exploration projects, including properties in close proximity to the company’s mills in the Athabasca Basin in Saskatchewan, Canada and in the Colorado Plateau, Henry Mountain and Arizona Strip regions of the Southwestern United States. Denison also has high potential exploration properties in Mongolia and, indirectly through its investments, in Australia. In Mongolia, Denison has a 70% interest in the Gurvan Saihan Joint Venture. The other parties are the Mongolian Government as to 15% and Geologorazvedka, a Russian government entity, as to the remaining 15%. In Australia, Denison has a 12% interest in Energy Metals Limited. Energy Metals has seven projects located in the Northern Territory and Western Australia covering over 4,000 square kilometres.

(a) Zambia — Kariba Project

The Kariba Project comprises a single prospecting licence (PL237) and is located approximately 200 kilometres south of Lusaka, the capital of Zambia. OmegaCorp has a 100% interest in the Kariba Project. The licence covers approximately 1,893 square kilometres and is held for uranium, fuel minerals, precious metals, base metals and industrial minerals.

OmegaCorp has reported several significant milestones with the Kariba Project:

| (i) | successfully generated enough data to allow a JORC compliant resource to be estimated on two of
the prospects. The inferred resource is currently estimated to be 13.7 million pounds U 3 O 8 ; |
| --- | --- |
| (ii) | applied modern geophysical techniques to the project with the completion of the first
helicopter borne survey in this area of Zambia; |
| (iii) | identified numerous geophysical targets for follow-up; |
| (iv) | completed a scoping study; and |
| (v) | identified a process flow sheet from very encouraging metallurgical test results. |

Work is continuing with a view to entering into a definitive feasibility study and ultimately bring OmegaCorp into production.

1. Denison’s intentions

4.1 Introduction

This section sets out the intentions of Denison relating to:

(a)	the continuation of the business of OmegaCorp;
(b)	any major changes to the business of OmegaCorp and redeployment of the fixed assets of
OmegaCorp; and,
(c)	the future employment of the present employees of OmegaCorp.

Denison’s intentions, as detailed below, have been formed on the basis of publicly available information concerning OmegaCorp which is known to Denison as at the date of this Bidder’s Statement. This is insufficient to enable Denison to reach a concluded view on its intentions set out below, and a final determination of any particular course of action will only be made after all material facts and circumstances have been considered. Accordingly, the statements set out in this section 4 are statements of Denison’s current intentions only, which may change as new information becomes available and circumstances become apparent or change.

4.2 Intentions upon acquisition of more than 90%

If Denison becomes entitled to at least 90% of OmegaCorp Shares, then subject to satisfaction or waiver of the other Conditions of the Offers, Denison intends to:

| (a) | proceed to compulsory acquisition of the outstanding OmegaCorp Shares in accordance with
the provisions of the Corporations Act; |
| --- | --- |
| (b) | procure an application to remove OmegaCorp from the official list of ASX; |
| (c) | appoint its own nominees to the board of directors of OmegaCorp and its subsidiaries and
seek the retirement of all current members of the boards of OmegaCorp and all associated
entities; |
| (d) | promptly conduct a review of all of OmegaCorp’s operations to accurately review the
synergy potential and identify potential cost savings. This will involve the review of
OmegaCorp’s operations and assets on a strategic and financial level; |

Folio 20 /Folio

PAGEBREAK

| (e) | promptly identify administrative functions across the combined group including corporate,
finance and accounting, marketing, human resources, information technology, legal and risk
management functions with a view to relocating these centralised head office functions to Denison’s
head office, and closing the OmegaCorp head office; |
| --- | --- |
| (f) | proceed with the development and commercialisation of the Kariba Project as soon as reasonably
possible; and |
| (g) | do all things reasonably necessary or required to give effect to and implement the IPO. |

As a consequence of this review, some employees may be made redundant. Employees who are made redundant will receive payments and other benefits in accordance with their contractual and other legal entitlements. Until Denison has completed the detailed review referred to above, Denison will not be in a position to determine the number of employees whose functions may be redundant or the timing of any redundancies.

The implementation of any of the steps in this section 4.2 would only be undertaken where those steps are in accordance with all applicable legal and regulatory requirements, the Listing Rules, the fiduciary and statutory duties of the directors of OmegaCorp and after considering the advice of legal and financial advisers.

4.3 Intentions upon acquisition of less than 90%

If Denison declares the Offers to be free from the Conditions in section 9.8 and Denison does not acquire at least 90% of OmegaCorp Shares and is therefore not entitled to compulsorily acquire the outstanding OmegaCorp Shares but OmegaCorp becomes a controlled entity of Denison, Denison intends (subject to the level of Denison’s shareholding in OmegaCorp) to:

| (a) | seek to appoint its own nominees to constitute all or a majority of the OmegaCorp board,
subject to the Corporations Act and to the constitution of OmegaCorp; |
| --- | --- |
| (b) | acquire OmegaCorp Shares over time so as to enable Denison to move to compulsory acquisition.
For example, as a result of the acquisition of OmegaCorp Shares in reliance of the “3% creep”
exception in item 9 of section 611 of the Corporations Act; |
| (c) | unless OmegaCorp has more than the required spread of shareholders under the Listing Rules,
procure an application to be made to remove OmegaCorp from the official list of ASX; |
| (d) | seek to implement such of the intentions as are detailed in section 4.2 as are consistent with
OmegaCorp being a controlled entity of Denison but not a wholly-owned subsidiary; and |
| (e) | do all things reasonably necessary or required to give effect to and implement the proposed
IPO. |

The implementation of any of the steps in this section 4.3 would only be undertaken where those steps are in accordance with all applicable legal and regulatory requirements, the Listing Rules, the fiduciary and statutory duties of the directors of OmegaCorp and after considering the advice of legal and financial advisers. In particular and, save for the IPO, the OmegaCorp directors may only implement any such steps if they consider the steps to be in the best interests of members of OmegaCorp as a whole.

At this stage, no decision has been made as to which persons will be appointed to the board of OmegaCorp. Denison has not assessed which directors of OmegaCorp it will seek to remove and which of those directors it will seek to retain.

4.4 Other intentions

Subject to the above, Denison does not foresee a significant shift from the current strategic direction of OmegaCorp in relation to its core businesses and does not intend to divest any of OmegaCorp’s businesses.

1. Funding of Offers

5.1 Maximum cash consideration

The consideration for the acquisition of OmegaCorp Shares to which the Offers relate will be satisfied wholly in cash and, if all the Offers are accepted, will be approximately $170 million (assuming all convertible securities are converted into OmegaCorp Shares).

5.2 Overview of funding arrangements

The cash consideration plus the funds to satisfy all other expenses incurred by Denison and relating to the Takeover Bid will be provided from existing cash balances which, as at 15 January 2007, were in excess of $180 million (Canadian dollars) (approximately $196 million Australian dollars) with no current debt.

On 22 December 2006 Dension announced that it had secured a commitment from Scotia Capital for a $100 million (Canadian dollars) credit facility to provide temporary financing of its Takeover Bid for OmegaCorp. However, as a result of Denison completing a private placement (announced on 19 December 2006) and successfully raising approximately $100 million (Canadian dollars) and Denison’s existing cash balances, Denison has decided not to proceed with the credit facility with Scotia Capital.

The funds available from the existing cash balances are sufficient to fund the maximum consideration payable pursuant to the Offers (including to all OmegaCorp Optionholders who exercise their OmegaCorp Options and accept the Offer) and fund related transaction costs associated with the Offers as well as fund Denison’s ongoing operations. The cash balances are not subject to security interests, rights of set off or other arrangements.

The existing cash balance is held in short term investment instruments with no restrictions on liquidation of these instruments.

In addition to cash balances, Denison has a portfolio of listed marketable securities which include shares in Fortress Minerals Corp. (TSX-V), JNR Resources Inc. (TSX-V), Energy Metals Corp. (TSX-V), Santoy Resources Ltd. (TSX-V). Energy Metals Limited (ASX) and Erdene Gold Inc. (TSX). These marketable securities have a combined market value, based on market prices as at the close of business on 15 January 2007, of approximately $79 million (Canadian dollars) (approximately $86 million Australian dollars). As such, Denison has financial resources significantly in excess of the maximum amount payable under the Offer, which can be made available to Denison to fulfil the cash consideration required under the Offer.

There are no hedging arrangements in place for movements in exchange rates in respect of the cash balances and portfolio of listed marketable securities of Denison set out above. Notwithstanding, Denison is of the opinion that the funds available from existing cash balances and the portfolio of listed marketable securities will be sufficient to fund the maximum consideration payable pursuant to the Offers, even in the event of a material adverse exchange movement.

1. Taxation considerations

6.1 Introduction

The following is a general outline of the main Australian income tax consequences for an Australian resident individual OmegaCorp Shareholder who disposes of OmegaCorp Shares by accepting the Offer.

The outline does not take into account or anticipate changes in the law (by legislation or judicial decision) or practice (by ruling or otherwise). The outline is also not exhaustive of all income tax considerations which could apply in the circumstances of any given OmegaCorp Shareholder. In particular, special rules apply to certain shareholders (such as persons not resident in Australia for income tax purposes, insurance companies, superannuation funds, banks, employees of OmegaCorp or its associated companies who acquired their OmegaCorp Shares in respect of their employment and those OmegaCorp Shareholders who hold their OmegaCorp Shares on revenue account, such as those OmegaCorp Shareholders who trade in shares or hold OmegaCorp Shares as trading stock) which are not covered by this outline.

All OmegaCorp Shareholders, and particularly those shareholders not specifically addressed by this outline as noted above (eg. Non-resident shareholders), should consult their own tax advisers regarding the Australian and, if applicable, foreign income tax consequences of disposing of OmegaCorp Shares given the particular circumstances which apply to them.

6.2 Capital gain or loss

The sale of OmegaCorp Shares pursuant to the Offer will involve the disposal by OmegaCorp Shareholders of their OmegaCorp Shares by way of transfer to Denison. This change in ownership of the OmegaCorp Shares will constitute a CGT event for Australian income tax purposes.

OmegaCorp Shareholders (who are Australian residents) may make a capital gain or incur a capital loss in respect of the sale of their OmegaCorp Shares that were acquired (or deemed to have been acquired) after 19 September 1985.

A capital gain will arise to the extent the capital proceeds from the disposal of OmegaCorp Shares (being the cash received by the OmegaCorp Shareholder under the Offer) exceed the cost base of the OmegaCorp Shares.

A capital loss will be incurred to the extent the capital proceeds are less than the reduced cost base of the OmegaCorp Shares.

The capital gains and capital losses of an individual taxpayer from all CGT events are aggregated to determine whether there is a net capital gain or net capital loss in any given tax year. A net capital gain may be discounted (as discussed below). Any net capital gain, after applicable discounts, is included in the assessable income of the individual taxpayer and may be subject to income tax. Net capital losses may not be deducted against other income for income tax purposes, but may be carried forward to offset against future capital gains.

If you acquired your OmegaCorp Shares at least 12 months before accepting the Offer.

Folio 23 /Folio

PAGEBREAK

Individuals, trustees of complying superannuation entities or trustees of trusts who acquired their OmegaCorp Shares at least 12 months before they dispose of them by accepting the Offer may be able to apply a “CGT Discount” percentage to the disposal of their OmegaCorp Shares. The CGT Discount entitles you to reduce any net capital gain on the disposal of the OmegaCorp Shares (after deducting any available capital losses) by:

| (a) | 50% in the case of individuals and trustees of trusts (other than a trust that is a complying
superannuation entity); or |
| --- | --- |
| (b) | 33 1 / 3 % for trustees of complying superannuation entities. |

The CGT Discount is not available to companies (not acting as trustees), nor does it apply to OmegaCorp Shares held less than 12 months. Special rules apply to determine whether shares have been held the requisite period and accordingly Shareholders in doubt about their own position should seek their own advice.

The above comments do not apply if you buy and sell shares in the ordinary course of business, or if you acquire the shares for resale at a profit. In those cases, any gain will generally be taxed as normal income.

Again Denison strongly recommends that you seek your own taxation advice in relation to the disposal of Your OmegaCorp Shares.

6.3 Transfer taxes

No stamp duty is payable for the transfer of listed shares (such as OmegaCorp Shares). No GST (goods and services tax) applies to the transfer of listed shares (such as OmegaCorp Shares).

8.4 Public announcements relating to the Takeover Bid

On 5 December 2006, Denison made a public announcement in relation to the Takeover Bid to TSX. Copies of this announcement may be obtained by OmegaCorp Shareholders without payment by contacting the offer enquiry line on 1300 653 890 (or +61 3 9415 4213 for international callers) or by accessing Denison’s website at www.denisonmines.com.

Announcements by Denison in relation to the Offer are attached as Annexure B.

8.5 Foreign Investment Review Board approval

As detailed in section 9.8 , the Offer is conditional upon Foreign Investment Review Board approval.

Denison is a foreign person for the purposes of the Foreign Acquisitions and Takeovers Act 1975 (Cth) (FATA) as a result of persons not ordinarily resident in Australia and foreign corporations holding an aggregate controlling interest (40%) in Denison. The FATA regulates the acquisition by foreign persons of interests in Australian businesses and properties by giving the Treasurer the wide discretion of prohibiting acquisitions he considers are contrary to the “national interest”. In practice, this function is delegated to FIRB.

Denison has given notification of the Takeover Bid to FIRB and has provided FIRB with a detailed submission and Denison is confident that the transaction is consistent with the Government’s foreign investment policy and expects a favourable response to be given in due course.

Denison will publish a notice as soon as practicable after FIRB approval has been given.

8.6 Bid Implementation Agreement

On 5 December 2006 Denison entered into a bid implementation agreement (BIA) with OmegaCorp, as amended by OmegaCorp and Denison by way of letter agreement announced to ASX by OmegaCorp on 22 December 2006. Other than the conditions of the Offer set out elsewhere in this Bidder’s Statement, the principle terms of the BIA are set out below.

(a) Break Fee

OmegaCorp will pay Denison a fee of 1% of the equity value of OmegaCorp determined as at 6 December 2006, if before the end of the Offer Period:

| (i) | a Competing Transaction is announced, or is open for acceptance, and, before the end of the
Offer Period, or, if later, the end of offer period or the effective date under the Competing
Transaction, a third party, being a person other than Denison or an associate, acquires control
(within the meaning of section 50AA of the Corporations Act) of OmegaCorp or any of its
subsidiaries; |
| --- | --- |
| (ii) | no Competing Transaction is announced, or is open for acceptance, but any director of
OmegaCorp: |

| (a) | fails to recommend that OmegaCorp Shareholders accept the Takeover Bid in the absence of a
superior offer; or |
| --- | --- |
| (b) | having made such a recommendation, makes a public statement which withdraws, revises or
qualifies that recommendation; or |

Folio 28 /Folio

PAGEBREAK

(iii) a Competing Transaction is announced, or is open for acceptance, and Denison varies the terms of the Takeover Bid so that the Offers (as varied) are at least equal to the Competing Transaction and any director of OmegaCorp:

| (a) | fails to recommend that OmegaCorp Shareholders accept the Takeover Bid (as varied) in the
absence of a superior offer; or |
| --- | --- |
| (b) | having made such a recommendation, makes a public statement which withdraws, revises or
qualifies that recommendation. |

OmegaCorp has agreed to pay the above break fee as fair and reasonable reimbursement for the costs and expenses incurred by Denison in relation to the Offer.

(b) Undertakings

OmegaCorp must not, and must not authorise, permit or require any of its Associates to either directly or indirectly solicit or initiate negotiations with third parties which may lead or may reasonably be expected to lead to a Competing Transaction.

(c) IPO

Before the end of the Offer Period OmegaCorp will:

(i)	cause OMC Resources to transfer the OMC MOZ Shares to Mavuzi; and
(ii)	obtain from OmegaCorp Shareholders all necessary statutory and/or regulatory approvals to
enter into such agreements and issue all such documents as required to enable Mavuzi to undertake
an initial public offer with OmegaCorp Shareholders and OmegaCorp Optionholders (who exercise their
OmegaCorp Options before the end of the Offer Period) as at the Relevant Date having a priority
entitlement to subscribe under the IPO for Mavuzi Shares on the basis of 1 Mavuzi Share for every 5
OMC Shares held with 1 free attaching Mavuzi Option for every 2 Mavuzi Shares subscribed which
shall be done as the OmegaCorp directors in their absolute discretion determine and subject to the
following:

| (a) | Mavuzi issuing 5,000,000 Mavuzi Rights to Denison, with 1 free attaching Mavuzi
Option for every 2 Mavuzi Shares subscribed; |
| --- | --- |
| (b) | Denison or its nominee acquiring the rights to uranium on properties currently owned by
OMC MOZ; |
| (c) | all assets of OMC MOZ, other than the Mavuzi Project and Meponda Project, are for
nil consideration transferred to OMC Resources or a wholly owned subsidiary of OMC
Resources incorporated for the purpose of acquiring those assets; |
| (d) | on the successful completion of the Takeover Bid, Mavuzi will make available to
Denison advisory assistance on an ongoing basis with regards to existing OmegaCorp assets; and |
| (e) | Mavuzi will enter into a strategic alliance with Denison for 3 years commencing on
the successful completion of the Takeover Bid by which Denison will have a right of first
refusal to acquire on commercial terms 100% of the rights to uranium on any properties
acquired by Mavuzi. |

On 22 January 2007 OmegaCorp announced that following confirmation from ASX that shareholder approval was not required for the IPO no shareholder meeting would be held. It is anticipated that the prospectus relating to the IPO will not be lodged and sent to eligible OmegaCorp Shareholders until after the end of the Offer Period.

8.9 Compulsory Acquisition of OmegaCorp Shares

(a) Post bid compulsory acquisition provisions

If Denison becomes entitled to compulsorily acquire any OmegaCorp Shares under section 661A of the Corporations Act, Denison will give notices to compulsorily acquire any outstanding OmegaCorp Shares in accordance with section 661B of the Corporations Act, even if the OmegaCorp Shares to which those notices relate:

| (i) | are issued after the Offer closes but before the notices are given (pursuant to
paragraph 661A(4)(b) of the Corporations Act; or |
| --- | --- |
| (ii) | are issued on exercise of the OmegaCorp Options up to six weeks after the notices
are given (pursuant to paragraph 661A(4)(c) of the Corporations Act). |

Denison may compulsorily acquire all outstanding OmegaCorp Shares at the Offer Price under these provisions if, during or at the end of the Offer Period:

| (iii) | Denison has a relevant interest in at least 90% (by number) of OmegaCorp Shares;
and |
| --- | --- |
| (iv) | Denison has acquired at least 75% (by number) of OmegaCorp Shares that Denison
offered to acquire under the Offer. |
| Holders of OmegaCorp Shares covered by a compulsory acquisition notice under Part 6A.1 of
the Corporations Act may apply to the Court for an order that their shares not be
compulsorily acquire. The Court may only make such an order if it is satisfied that the
consideration is not fair value for the securities. | |

(b) General compulsory acquisition provisions

If Denison becomes entitled to compulsorily acquire OmegaCorp Shares and OmegaCorp Options under section 664A of the Corporations Act, Denison will give notices to OmegaCorp Shareholders (unless Denison is entitled to proceed to compulsory acquisition of the OmegaCorp Shares pursuant to section 661A of the Corporations Act described above) and OmegaCorp Optionholders to compulsorily acquire any outstanding OmegaCorp Shares and OmegaCorp Options in accordance with section 664C of the Corporations Act.

Denison will be able to compulsorily acquire all outstanding OmegaCorp Shares and OmegaCorp Options under section 664A of the Corporations Act if Denison’s voting power in OmegaCorp is at least 90% and Denison (either alone or with related bodies corporate) holds full beneficial interests in at least 90% (by value) of the aggregate of all OmegaCorp Shares and OmegaCorp Options and:

| (i) | lodges a compulsory acquisition notice with ASIC in accordance with section 664C(2)
of the Corporations Act within six months of achieving that 90% holding (and dispatches
the notice to OmegaCorp Shareholders and OmegaCorp Optionholders by the following
Business Day); and |
| --- | --- |
| (ii) | obtains the report of an expert stating whether, in the
expert’s opinion, the terms proposed in
the notice give fair value for the securities covered. |

OmegaCorp Shareholders and OmegaCorp Optionholders whose OmegaCorp Shares and OmegaCorp Options are covered by the compulsory acquisition notice are entitled to object to the acquisition by signing an objection form and returning it to Denison. If OmegaCorp Shareholders holding 10% or more of the OmegaCorp Shares covered by the notice object, Denison will need Court approval before the relevant acquisition can proceed.

PAGEBREAK

(c) Compulsory offer to buy out OmegaCorp Shares and OmegaCorp Options

If Denison is required to offer to buy out outstanding OmegaCorp Shares under section 662A of the Corporations Act or OmegaCorp Options under section 663A of the Corporations Act (and no relevant modification of those sections apply), Denison will give notices to the relevant OmegaCorp Shareholders and OmegaCorp Optionholders offering to buy out their OmegaCorp Shares in accordance with section 662B of the Corporations Act and their OmegaCorp Options in accordance with section 663B of the Corporations Act.

Denison must serve a notice offering to buy out all remaining OmegaCorp Shares and OmegaCorp Options if, at the end of the Offer Period, Denison and its Associates have relevant interests in at least 90% (by number) of OmegaCorp Shares. In the case of a notice to holders of OmegaCorp Options, the notice will need to be accompanied by a report of an expert stating whether, in the expert’s opinion, the terms proposed in the notice give fair value for the OmegaCorp Options. OmegaCorp Shareholders and OmegaCorp Optionholders who hold shares or options covered by the notice may, but need not, accept the offer in the notice. The notices must be dispatched to OmegaCorp Shareholders and OmegaCorp Optionholders within one month after the end of the Offer Period and on the same day as they are lodged with ASIC or the next Business Day. OmegaCorp Shareholders and OmegaCorp Optionholders who wish to accept the offer must do so within one month after the notice is dispatched to them.

Denison is not required to give a notice to OmegaCorp Shareholders offering to buy out their OmegaCorp Shares under section 662B of the Corporations Act if it has given those shareholders a compulsory acquisition notice under section 661B of the Corporations Act. Accordingly, Denison does not anticipate that it will need to make an offer to buy out outstanding OmegaCorp Shares under section 662A of the Corporations Act as it will proceed to compulsory acquisition of those shares in accordance with section 661A of the Corporations Act as outlined in section 8. 9(a) .

ANNOUNCEMENT TO THE AUSTRALIAN STOCK EXCHANGE: 6 DECEMBER 2006

CASH TAKEOVER BID RECEIVED FOR ALL SHARES IN OMEGACORP LTD

The Directors of OmegaCorp Limited ( “the Company” or “OmegaCorp” ) are pleased to announce that a conditional cash takeover bid for any and all its issued shares has been received from Denison Mines Corp.

The cash takeover offer price is $1.10 for every OmegaCorp share ( “Denison offer” ). The offer reflects a premium of approximately 25% to the volume weighted average price for OmegaCorp shares over the previous 20 trading days. Further details of the Denison offer are attached, including the Bid Terms which are included as Schedule 2 to this announcement and Denison’s press release of earlier today is included as Schedule 3 to this announcement.

The Directors believe that the Denison offer provides OmegaCorp shareholders with the opportunity to realize benefit from the Company’s wholly owned Kariba Project sooner than if the Company sought to develop the Kariba Project itself.

The Denison offer involves the spin-off of OmegaCorp’s Mavuzi Project in Mozambique. It is intended to obtain all approvals required to distribute in specie all of shares in a company (“Newco”) which is to be incorporated and will own the Mavuzi Project to the OmegaCorp Shareholders on a 1 for 4 basis and then seek to list Newco on ASX. Further details of Newco and the Mavuzi Project are attached as Schedule 1 to this announcement.

OmegaCorp’s Directors have considered the terms of the Denison offer and unanimously recommend that OmegaCorp shareholders accept the offer in the absence of a superior offer. Furthermore, the Directors intend to accept the Denison offer for their own shares in the absence of a superior offer.

The Company has entered into a Bid Implementation Agreement with Denison that may result in OmegaCorp paying a break fee of 1% of the equity value of OmegaCorp in certain limited circumstances. OmegaCorp has also agreed not to, during the period of Denison’s Offer, initiate negotiations which may lead to a competing offer to the Denison offer. A copy of the Bid Implementation Agreement is attached as Schedule 4 to this announcement.

Argonaut Capital Ltd have been retained to advise the Company on this transaction.

SCHEDULE 1 — DETAILS OF NEWCO AND THE MAVUZI PROJECT

Newco

Newco will issue 5 million rights to Denison, each right enabling them to acquire 1 Newco share for $0.20 per share ( “Newco rights” ).

Newco will also distribute up to 38.65 million shares on a 1 for 4 basis, together with 1 additional Newco right for every 3 Newco shares held, to OmegaCorp shareholders. All approvals for this process and the entitlement date will be obtained prior to the closing of the Denison offer. Following the issue to Denison and OmegaCorp’s shareholders, Newco’s capital structure will be as follows:

Holder	Distributed — Newco shares	Newco shares — from rights	Proceeds to Newco
Omegacorp shareholders	38,650,000	12,880,000	A$	2,580,000
Denison	—	5,000,000	A$	1,000,000
Total	38,650,000	17,880,000	A$	3,580,000

The Mavuzi Project

The Mavuzi Project in Mozambique comprises five contiguous Prospecting Licences that cover the whole of the Mavuzi Mine area and total approximately 700 square kilometers. The Project is located some 40 kilometers northwest of the provincial centre of Tete in northwestern Mozambique and has been the focus of the Company’s exploration initiatives in Mozambique for over 12 months.

The Project covers a large portion of the Mavuzi Valley, which drains to the southwest into the Zambezi River. The area has a long history of exploration and mining for many commodities including copper, nickel, molybdenum, cobalt and platinum group elements associated with the Tete Complex. Newco will focus on the exploration of the Mavuzi Project for these metals. Denison will retain the uranium rights in respect to the Mavuzi Project.

ANNOUNCEMENT TO THE AUSTRALIAN STOCK EXCHANGE: 22 DECEMBER 2006

CHANGE TO STRUCTURE OF ENTITLEMENTS UNDER MAVUZI SPIN OFF

Further to its ASX announcement dated 6 December 2006, the Board of OmegaCorp Limited (“the Company”) advises that following advice as to the taxation ramifications of the proposed Mavuzi Project spin off (“Newco”), it will be restructured from an in specie distribution and rights issue to a priority entitlement issue. All other details in relation to Denison’s conditional cash takeover bid of $1.10 for any and all OmegaCorp’s issued shares remain unchanged.

The major points of the revised spin off are as follows:

• Newco will own the Mavuzi Project (“the Project”) in Mozambique, with Denison retaining the uranium rights in respect to the Project;

• Newco will undertake an initial public offering (“IPO”) and seek quotation of its shares on ASX following completion of the Denison take over offer. A prospectus (which will have an application form attached that will need to be completed) will be made available when Newco shares are offered under the IPO;

• OmegaCorp shareholders will now be entitled to subscribe as a priority for approximately 31 million shares of the IPO at $0.20 per share, to be set aside for OmegaCorp shareholders on a 1 for 5 basis, plus a 1 for 2 free attaching Listed Option exercisable at $0.20 over three years. The ex-date for the priority entitlement will be announced by the Company as soon as possible; and

• Denison will be entitled to subscribe as a priority for 5 million shares of the IPO at $0.20 per share, plus a 1 for 2 free attaching Listed Option exercisable at $0.20 over three years.

Newco’s capital structure is still to be completed, however, it will include entitlements rights for OmegaCorp shareholders and Denison as follows:

	Newco Shares — from Priority	Newco Options — from Priority	Proceeds to Newco
Holder	Entitlement	Entitlement	(ex Options)
Omegacorp/IPO shareholders	31,000,000	15,500,000	$ 6,200,000
Denison	5,000,000	2,500,000	$ 1,000,000
Total	36,000,000	17,500,000	$ 7,200,000

The Newco Board will initially comprise three existing OmegaCorp directors, Messers Ian Middlemas, Matthew Yates and Mark Pearce.

Further details of Newco, including a detailed description of its assets and capital structure etc, will be included in the Explanatory Memorandum in the Notice of General Meeting to be sent to shareholders shortly.

ANNOUNCEMENT TO THE AUSTRALIAN SECURITIES EXCHANGE:

22 JANUARY 2007

MAVUZI RESOURCES LIMITED IPO

The Board of OmegaCorp Limited (“the Company” or “OmegaCorp”) is pleased to announce details of the initial public offer (“IPO”) and listing of the Company’s wholly owned subsidiary, Mavuzi Resources Limited (“Mavuzi”), on the Australian Securities Exchange (“ASX”). Mavuzi will have direct interests in a number of mineral exploration projects in Mozambique which will initially focus on the copper and gold potential in the project areas. Further details of these projects are contained in Schedule A.

The offer in the Prospectus will consist of approximately 44 million shares at $0.20 each to raise up to $8.8 million before costs. Further details of the proposed capital structure of Mavuzi are contained in Schedules B and C and include:

1. The Priority Offer – persons registered as shareholders of OmegaCorp on 29 January 2007 or persons issued shares in OmegaCorp on exercise of options during the period of Denison Mines Corp’s offer will be entitled to subscribe for shares in Mavuzi on a 1 for 5 basis for up to approximately 31 million shares. In addition, Denison will be entitled to subscribe for 5 million shares in Mavuzi.

2. The Public Offer – a further 8 million shares, plus any shares not subscribed for under the Priority Offer, will be offered to the public; and

3. Free attaching listed options – in addition, for every two shares issued under both the Priority Offer and the Public Offer, Mavuzi shareholders will receive, for no further consideration, one listed option exercisable at $0.20 at any time up to 30 June 2010.

Following confirmation from ASX, shareholder approval is not required for the Mavuzi IPO and consequently a general meeting is not required. Specifically, ASX Listing Rule 7.17 and 11.4 does not apply, the latter on the basis that the Mavuzi IPO of the exploration projects in Mozambique is not a disposal of a major asset.

Mavuzi expects to lodge with the ASIC and make available a Prospectus (which will be accompanied by an application form that will need to be completed by persons wanting to acquire securities) for the Mavuzi IPO by mid 2007, however this is an indicative date and the completion of the Prospectus will be subject to Mavuzi obtaining all regulatory approvals in Mozambique, and the completion of all due diligence procedures.

The Mavuzi Board will initially comprise three existing OmegaCorp directors, Messrs Ian Middlemas, Matthew Yates and Mark Pearce. Mr Yates will be the Managing Director of Mavuzi (further details of Mavuzi’s directors and senior management are contained in Schedule E). The Mavuzi Board will be responsible for managing the Mavuzi IPO process.

Mozambique Projects Summary — Mavuzi

Background

In 2005 OmegaCorp Minerais Limitada (Mozambique) (“OMC Moz”) was granted four contiguous prospecting licences covering a total area of approximately 700 square kilometres around the abandoned Mavuzi Uranium Mine (“Mavuzi Mine”) in the Tete Igneous Complex of north-western Mozambique.

Mavuzi Project

Initially, OMC Moz focused its efforts at the Mavuzi Mine on a preliminary program of RC drilling along the projected extensions of the Mavuzi shear near the Mavuzi Mine. The objective was to test for the possible presence of near surface, open-pitable uranium mineralisation in carbonate lodes and silicified shears and the surrounding wall rock. The assay results from the preliminary drilling program were disappointing and consequently the exploration initiative was broadened.

In 2006 OMC Moz started a regional program of stream sediment sampling over the whole licence block in the search for indications of the presence of additional uranium, precious and base metal mineralisation. Although many of the analytical results from the collected samples are still outstanding, this work has identified a gold anomaly in stream sediments covering approximately seven kilometres long by one kilometre wide in the Boa Viseau target area. Anomalous copper, thorium, uranium, lanthanum and cerium provide variable support to the gold, and the anomaly straddles the contact between a magnetite bearing metacarbonate and the underlying gneiss basement. There is potential for the mineralisation being targeted in this area to have iron-oxide-copper gold (IOCG) affinities.

In November 2006 the whole licence block was flown with a low-level, heliborne, radiometric and magnetic, geophysical survey. Only the most preliminary results are currently available and the data is still being processed and interpreted.

PAGEBREAK

Work Completed by OMC Moz

The major items of mineral exploration work carried out to date are summarised below:

• data compilation and initial field reconnaissance;

• stream sediment sampling: whole block (890L, 1054L, 1055L finished – 50% of results pending; 1119L planned for 2007);

• mapping and ground radiometrics of Boa Viseau (in progress);

• soil sampling at Boa Viseau (400 m x 50 m grid) (results pending); and

• heliborne geophysics (approx. 4250 line km/200m line spacing – results pending).

Meponda Project

The Meponda Project comprises three contiguous licences covering approximately 472 square kilometres. The Project is situated 60 km west of the regional capital Lichinga in Niassa Province of northern Mozambique. The licences cover the Meponda Alkaline Igneous Complex. The complex is exposed as a prominent, elongate mountain flanking the eastern edge of the Lake Malawi rift valley. This mountain, known as Monte Numale, is composed of a cream to pink, coarse grained, syenitic gneiss with a distinctly nodular appearance. The Project was acquired for its potential to host uranium and other elements. Work completed to date has been restricted to a data compilation and reconnaissance field work.

Mavuzi IPO

Mavuzi expects to lodge a Prospectus for the Mavuzi IPO with the ASIC by mid 2007. Following confirmation from ASX, shareholder approval is not required for the Mavuzi IPO and consequently a general meeting is not required. Specifically, ASX Listing Rule 11.4 does not apply on the basis that the Mavuzi IPO of the exploration projects in Mozambique does not constitute the disposal of a major asset.

The completion of the Prospectus will be subject to Mavuzi obtaining all regulatory approvals in Mozambique, including but not limited to approvals for the transfer of shares in OMC Moz to Mavuzi. Furthermore, appropriate due diligence procedures will need to be completed prior to lodgement of the Prospectus, so an indicative timetable for the IPO is not yet available.

The Mavuzi IPO will be funded by an interest-free intercompany loan from OmegaCorp, to be repaid in full immediately after the IPO, and will be managed by three of OmegaCorp’s current directors. It is anticipated that up to 2 million shares will be issued to OmegaCorp as consideration for the transfer of the Mavuzi and Meponda Projects.

The information in this report that relates to Exploration Results, Mineral Resources or Ore Reserves is based on information compiled by Mr. Matthew Yates, who is a Member of The Australian Institute of Geoscientists (AIG). Mr. Yates is a full-time employee of Beacon Exploration Pty Ltd, a consultant of OmegaCorp Limited. Mr. Yates has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2004 Edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’.

PRESS RELEASE

DENISON TO ACQUIRE OMEGACORP LIMITED

Toronto, ON — December 5, 2006 — Denison Mines Corp. (“Denison”) (IUC:TSX, DEN:TSX) is pleased to announce a takeover offer to acquire any or all of the issued and outstanding shares of OmegaCorp Limited (“Omega”) (ASX:OMC) at a price of AU$1.10 per share for a total consideration of approximately AU$170 million (CDN$154 million). The offer reflects a premium of approximately 25% to the volume weighted average price for Omega shares in the previous 20 trading days.

Omega’s directors have unanimously recommended that shareholders accept the Denison offer in the absence of a superior offer. Omega’s directors have also unanimously indicated that they intend to accept the Denison offer with respect to their own shareholdings in the absence of a superior offer or if there is a bid by a third party that is matched by Denison. Omega has also agreed to a break fee of 1% of the equity value of Omega under specified circumstances together with a right to match provision in favour of Denison. Omega has agreed not to solicit other offers during the offer period.

The Denison offer contemplates the spin-off of the Mavuzi assets in Mozambique to Omega shareholders. Omega intends to seek all necessary approvals to distribute the shares to the Omega shareholders (as at a record date to be determined) on a 1 for 4 basis in a company (“Newco”) which is to be incorporated and will own the Mavuzi assets. Omega will seek to list Newco on the Australian Stock Exchange (“Distribution in Specie”). Denison will retain the uranium rights in respect of the Mavuzi assets.

Denison’s offer is subject to a number of conditions including receipt of regulatory approvals and no material adverse changes to Omega. A copy of the Bid Implementation Agreement will be available on www.sedar.com. The Bidder’s Statement to Omega’s shareholders is expected to be available within 3 weeks.

Omega is an Australian listed mineral exploration company which has a portfolio of uranium projects in southern Africa, including the advanced stage Kariba Project in Zambia. Please see attached map.

Kariba Uranium Project – Zambia

Omega holds a 100% interest in the Kariba Uranium Project located approximately 200 kilometres south of Lusaka. Encompassing an area of over 1,890 square kilometers, three main areas of mineralization have been identified to date – Mutanga, Dibwe and Bungua, with several targets in each area.

Current inferred resources1, prepared by FinOre Mining Consultants in accordance with the JORC Code, at the Mutanga and Dibwe areas are estimated at 16,400,000 tonnes grading 380 ppm U3O8 containing 13.7 million pounds U3O8 at a 200 ppm U3O8 cut-off. Existing data supports resource upside potential here and elsewhere within the project.

The mineralization on the property has not been estimated in conformity with National Instrument 43-101 (“NI 43-101”), and consequently there are no 43-101 compliant resources or reserves at this time. All resource estimates quoted above are based on prior data and reports obtained and prepared by previous operators and information, including Omega. Denison has not completed the work necessary to verify the classification of the mineral resource estimate. Inferred resources have a great amount of uncertainty as 2 to their existence, and great uncertainty 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. The properties will require further valuation which Denison’s management and consultants intend to carry out in due course upon completion of the acquisition.

Omega has completed a scoping study2 of the Kariba project (the “Study”) utilizing an open pit, alkali leach mining operation. The Study, conducted by MDM Engineering (Pty) Ltd of South Africa, considers the engineering and costing of all the plant, equipment and associated infrastructure facilities such as water, power and transportation

Folio 61 /Folio

PAGEBREAK

requirements. Results of the Study suggest that the project could support the production of 1.5 million pounds of U3O8 per annum at an initial estimated operating cost of US$23 per pound (determined to a nominal accuracy of +/- 30%). The mining rate for the project was estimated at 2 million tonnes per annum, with a 90% metallurgical recovery. Using these parameters, the operation could support a mining operation for about six years. This was considered to be a base case for the project as there is potential to increase the overall resource base and therefore the life of the mine.

Capital costs (determined to a nominal accuracy of +/-30%) for the process plant and infrastructure were estimated at US$41 and US$17 million respectively. A further US$1.5 million has been estimated for the “first fill” of reagents.

The Study was completed using the following parameters:

• Life of mine estimate	6 - 10 years
• Ore Mining Rate	2.0 Million tonnes per annum
• Cut off grade	200 parts per million (ppm) (.02% U3O8)
• Mining grade	360 – 420 ppm (.036% - .042% U3O8)
• Recovery	90%

The key considerations in the Study were scale, throughput rate, project life, and community and environmental impacts. The minimum project life was expected to be six years, but with the potential to be at least ten, given the number of untested targets and other areas drilled by AGIP, who explored the area extensively in the past. To this end, the Study completed to date is considered as a base case scenario.

The proposed mining site is regionally well serviced with infrastructure, with grid power available within sixty kilometres from the site. Water is available from nearby Lake Kariba if required, or from on site sources. The study has used the former option.

The mining of both overburden and ore is described as a relatively simple process requiring limited blasting. The stripping ratio of the Mutanga deposit was estimated at <2:1, with the Dibwe deposit expected to be higher, due to the nature of the mineralisation. The stripping ratio for the life of the operation was not expected to exceed 4:1.

The current consideration is to locate the plant and associated infrastructure approximately one kilometre south of the Mutanga deposit. This area has been chosen due to its suitability, proximal nature and access.

A conceptual flow sheet was generated that incorporates the newly conceived concept of upgrading the ore ahead of its processing by running the milled ore through screens and an attrition scrubber. The leaching commences in the milling part of the circuit, with the introduction of modest heat (60oC) and continues in the leach tanks and counter-current-decant (CCD) part of the circuit. The process utilises an alkali leach, processing up to two million tonnes of ore per annum. A metallurgical recovery factor of 90% has been applied in the scoping study based on extensive testing.

The Study is preliminary in nature and it is based entirely on inferred resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. The Study also contained assumptions relating to ore density, expectation of upgrading of resources and use of historic drillhole locations. There is no certainty that the economic results from the Study will be realized. The Study is a preliminary assessment of the project and Denison believes that the operating and capital costs could be higher. 3

Denison’s management believes that the acquisition of Omega will fit well into its growth strategy in terms of development scheduling and uranium production. The Omega assets are expected to add significantly to Denison’s

uranium resources and bring additional near term production capacity, as well as establishing Denison in Africa.

These JORC compliant resources have not been estimated in accordance with NI 43-101. Denison has not verified any of the data disclosed in the Study that formed the basis for the inferred resources referred to in this release. Denison has not verified any of the sampling, or analytical or test data underlying the information or opinions that formed the basis of that Study. This Study must be considered as a preliminary assessment, and the inferred resources contained therein have to be considered too speculative geologically to have any economic considerations applied to them to enable them to be categorized as mineral reserves. There is no certainty that the assumptions in this preliminary assessment will be realized. The Study provides that: little knowledge of the geology controls on mineralization and the mineralogy of the deposits is available; there is uncertainty concerning the reconciliation of assay grade of the rock returned and of downhole radiometric probing; at Dibwe, which hosts 48% of the inferred resources, there is uncertainty regarding both U3O8 grade and the position of the down hole mineralization intercepts; the in-situ dry density calculations are based on samples that do not have a known location. Denison has not verified any of the data that underpinned the assumptions contained in this preliminary assessment. No Denison employee has visited the project or has access to more information other than that contained in the Study.

The Study’s Qualified Person is Mr. Dodd of MDM Engineering Limited of Johannesburg, South Africa. Mr. Dodd holds a BSc (Hons) in Chemical Engineering and is a fellow of the South African Institute of Mining Metallurgy with 32 years experience in the field of extractive metallurgy.

PRESS RELEASE

DENISON ANNOUNCES EXPLORATION UPDATE

Toronto, ON — January 24, 2007... Denison Mines Corp. (“Denison” or the “Company”) (DML:TSX) is pleased to report on its 2007 exploration activities. Please see attached map.

Athabasca Basin

In the Athabasca Basin, Denison is participating in over 30 exploration projects, primarily located in the southeast part of the Basin and within open pit depths and trucking distance of the operating mills. Denison, together with a subsidiary of the AREVA Group (“AREVA”) and Cameco Corporation, now control the majority of the highly favourable geology in the prolific southeastern sector of the Basin.

Denison is participating in nine major drill programs during the current winter season in the Basin. Denison is operator on the Wheeler River, Park Creek, Huard-Kirsch and Crawford Lake joint ventures, and the 100% owned Johnston Lake project. JNR Resources Inc. will operate the 75% owned Moore Lake project until June, 2007 when Denison will take over. Near the McClean Mill, joint venture partner AREVA is operator of the Midwest, Wolly and McClean projects.

On Denison’s operated and non-operated projects, a total of approximately 48,000 metres of drilling is planned this winter, consisting of approximately 110 holes using 8 diamond drill rigs. This meterage represents a substantial increase over that of each of its two predecessor companies, and reinforces Denison’s commitment to exploration in the Basin. The Company’s projects in the Basin represent a good balance of grass roots, mid stage, and developed projects.

In addition to these major drill campaigns, Denison is carrying out a number of different geophysical surveys to identify targets for future drill programs. Almost 5,500 line kilometres of airborne geophysical surveys are currently being flown over three properties as an initial screening tool. Denison is also carrying out a large number of ground geophysical surveys on eight properties, where over 382 line kilometres of Fixed Loop Time Domain EM surveys, 342 line kilometres of HLEM (Horizontal Loop Electromagnetics) and over 120 line kilometres of DC Resistivity surveys will be completed this winter. Over 1,000 line kilometres of ground magnetic surveys will also be carried out in conjunction with the above.

At the Midwest project where Denison maintains a 25.17% interest, operator AREVA’s focus will be on delineation drilling on the Mae zone, one of the most economically important discoveries in recent years. Denison will report on any significant results as they become available.

Southwest United States

In the United States, Denison’s exploration activities are ramping up after a 25 year hiatus. An estimated 90,000 feet (28,000 meters) of drilling is planned in 2007, with work initially concentrating near the Company’s permitted and producing mines in Utah and Colorado.

Folio /Folio

PAGEBREAK

Mongolia

In Mongolia, Denison is committing to a substantial increase in work over previous years. Denison maintains a majority interest in two deposits and a large number of exploration projects which have returned uraniferous intersections. Following a late 2006 review of decade-long exploration programs by Denison and predecessor companies, a decision was made to substantially accelerate work on two advanced deposits, potentially containing economically recoverable resources, and to also accelerate exploration on these and other high potential projects. A major 160,000 metre, two-year drill program has been authorized in order to investigate these targets and prepare two areas for prefeasibility work in preparation for commercial production by 2010.

Australia

Energy Metals Limited (“Energy Metals”) continues to receive good results from its Bigrlyi joint venture near Alice Springs in Australia as announced by it on January 12, 2007. Denison owns a 12% equity interest in Energy Metals and is looking to further participate in advanced projects.

William Kerr, P. Geol., a Qualified Person pursuant to NI 43-101, has reviewed the contents and technical information contained in this news release. Mr. Kerr is Vice President Exploration for Denison.

Denison Mines Corp. is 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.

PRESS RELEASE

DENISON ANNOUNCES OPERATIONS UPDATE

Toronto, ON — January 30, 2007... Denison Mines Corp. (“Denison” or the “Company”) (DML:TSX) is pleased to announce that it has awarded E.D. Mining, LLC, the contract to conduct contract mining at the Company’s Sunday mine in the United States. Mining has commenced and production from the Sunday mine is expected to add about 100 tons of ore daily to the current daily U.S. production from the Pandora, Topaz and St. Jude mines that will aggregate to about 550 tons per day by mid-2007. Production from these mines, in the area known as the Colorado Plateau District, is being hauled to Denison’s White Mesa Mill and is currently being stockpiled. Milling of conventional ore is scheduled for early 2008 when the milling of the alternate feed is completed and at least 150,000 tons of ore is stockpiled at the Mill.

The Company will be evaluating the Rim and Van 4 mines on the Colorado Plateau with the plan to commence operations in 2007.

At the Tony M mine within the Henry Mountains Complex, which is located west of the Colorado Plateau District, permitting is progressing well and it is expected that full operational permits will be received by the end of the first quarter, 2007. Rehabilitation of the mine will commence within the next few months under the exploration permit that the Company has in place for the Tony M mine. Production from this mine is anticipated in the third quarter of this year.

At the White Mesa Mill, the Company has implemented a US $15 million modernization program which will include modifications to the mill circuit, upgrading of equipment and relining of tailings cell 4A. The Mill continues to process alternate feed material from several large contracts. Production at the White Mesa mill in 2006 was approximately 280,000 pounds of U 3 O 8 and it is anticipated that production in 2007 will be about 400,000 pounds. By 2010, production levels from U.S. operations are anticipated to reach greater than 3 million pounds U 3 O 8 and 4.5 million pounds of vanadium. The Company intends to maximize the advantage of its ownership of one of only two operating mills in the U.S. To that end, in addition to processing its own ore and alternate feed material, the Company is negotiating toll milling arrangements with other mines in the region.

In Canada, mining at the Sue E pit at McClean Lake in northern Saskatchewan is proceeding on schedule with a scheduled completion by the end of this year. U 3 O 8 production at the McClean Lake mill, in which Denison has a 22.5% interest, was 1,795,000 pounds in 2006 (Denison’s share was 404,000) and it is anticipated that the joint venture production in 2007 will be 2.2 million to 3 million pounds. The large variance in this estimate is a result of the uncertainty associated with the drilling of the bore holes for the jet boring mining at the McClean North deposit, the completion of mill modifications to increase the leaching capacity at the mill and the time required to obtain regulatory approvals to implement the mill modifications. Production levels at McClean should continue to increase and by 2011, with Midwest ore production and another mill expansion, production should be about 9 million pounds per year.

Denison Mines Corp. is 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.

(“DMI”) and International Uranium Corporation (“IUC”), the current Annual Information Form of DMI filed with the securities regulatory authorities in Canada and available at www.sedar.com and IUC’s Annual Report on Form 20-F filed with the securities regulatory authorities in Canada and available at www.sedar.com . Although management of Denison has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking statements, there may be other factors that cause results not to be as anticipated, estimated or intended.

There can be no assurance that such statements will prove to be accurate, as 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 refer to the respective Annual Information Forms of DMI and, IUC, each for the 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 information relating to their mineral resources and mineral reserves.

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 Mineral Resources” have a great amount of uncertainty as to their existence, and 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.
