Denison to Acquire OmegaCorp Limited

TORONTO, ONTARIO--(CCNMatthews - Dec. 5, 2006) - Denison Mines Corp. ("Denison") (TSX:IUC)(TSX:DEN) 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 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 resources(1), 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 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 study(2) 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 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 less than 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 (60 degrees C) 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.

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.

Dundee Securities Corporation served as financial advisor to Denison on the acquisition.

The August 2006 report's Qualified Person is Mr. Malcolm Titley, Principal Consultant and Director of FinOre Mining Consultants. Mr. Titley is a BSc qualified geologist and chemist with 25 years combined mining industry and resource estimation experience.

(2)The Study is a preliminary assessment, which has been completed by a number of industry recognized consultants engaged by Omega, and is based on the current Inferred Mineral Resource estimated in compliance with the JORC Code. 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.
