Denison and Fission Execute Definitive Arrangement Agreement

TORONTO, ONTARIO--(Marketwired - July 28, 2015) - - Denison Mines Corp. (TSX:DML)(NYSE MKT:DNN) ("Denison") and Fission Uranium Corp. (TSX:FCU)(OTCQX:FCUUF)(FRANKFURT:2FU) ("Fission") are pleased to announce that Denison and Fission have entered into a definitive arrangement agreement (the "Arrangement Agreement") which replaces the binding letter agreement (the "Binding Letter Agreement") previously announced on July 6, 2015. Pursuant to the Arrangement Agreement, Denison has agreed to combine its business with Fission by way of a court-approved plan of Arrangement (the "Arrangement").

Information regarding the Arrangement will be contained in information circulars that each of Denison and Fission will prepare, file and mail in due course to their respective shareholders in connection with the special meetings of each of the Denison and Fission shareholders to be held to consider the Arrangement expected to occur in October 2015 or such date as the parties may agree. All shareholders are urged to read the information circulars once they become available as they will contain additional important information concerning the Arrangement.

The Arrangement creates a leading Canadian focused diversified uranium company - combining high quality assets and the management teams of two highly respected companies. Headlining the asset portfolio of the combined company will be two flagship uranium exploration and development projects: Fission's 100% owned Patterson Lake South Project, and Denison's 60% owned Wheeler River Project, both located in the Athabasca Basin, in Northern Saskatchewan, Canada.

Transaction Highlights

  • Consolidation of Strategic Uranium Assets: An unrivaled portfolio of strategic uranium asset interests in the Athabasca Basin, headlined by Fission's 100% owned PLS Project and Denison's 60% owned Wheeler River Project, Denison's interests in the Midwest, McClean Lake, Waterbury Lake, Mann Lake, and Wolly projects, and Denison's strategic 22.5% ownership interest in the McClean Lake Mill;
  • Continued Exploration Potential: Exploration foothold in both the historically prolific Eastern Athabasca Basin and the emergent Western Athabasca Basin, with a dominant combined land package of over 430,000 hectares and a sizeable base of mineral resources defined under NI 43-101;
  • Free Cash Flows: The toll-milling of ore from the Cigar Lake mine under a toll milling agreement between the McClean Lake Joint Venture and the Cigar Lake Joint Venture and management fees from Uranium Participation Corporation are expected to provide the combined company with a source of cash in the future to fund its activities;
  • Complimentary Combined Management Team and Board of Directors: Management from Fission and Denison will be combined, offering expertise and skill in the uranium industry and mergers and acquisitions, as well as the proven ability to finance ambitious exploration programs and successfully explore and develop uranium mining projects;
  • Increased Liquidity: Increased scale is expected to enhance trading liquidity and access to global capital markets; and
  • Valuation Upside: Various monetization options in respect of Denison's African exploration and development portfolio, including the Falea project in Mali and the Mutanga project in Zambia, are being considered by the combined company and may be pursued when market conditions permit.

Management Team and Board of Directors

The Arrangement Agreement provides that all necessary steps will be taken to ensure that, upon the closing of the Arrangement, Devinder Randhawa, Ross E. McElroy and David Cates will be appointed as the Chief Executive Officer, President and Chief Operating Officer and Chief Financial Officer of the combined company, respectively, and that the Board of Directors of the combined company will be reconstituted to consist of ten (10) directors (five from each of the current Denison and Fission Boards of Directors), including Catherine Stefan, Ron Hochstein, Lukas Lundin (non-Executive Chairman), Brian Edgar, Devinder Randhawa, Ross E. McElroy, Frank Estergaard, William Marsh, Jeremy Ross and Joo Soo Park, as nominee of Korea Electric Power Corporation.

Transaction Details

The Arrangement will be effected by way of a Plan of Arrangement completed under the Canada Business Corporations Act among Denison, a wholly owned subsidiary of Denison, and Fission, and it must be approved by the Supreme Court of British Columbia. The Arrangement also requires shareholder approval from two thirds of the votes cast by the holders of Fission common shares (the "Fission Shareholders"), plus any minority approval of Fission Shareholders that may be required by Multilateral Instrument 61-101, and approval of 50% plus 1 of the votes cast by the Denison shareholders at their respective shareholder meetings. Denison shareholders will also be asked to approve a 2-for-1 share consolidation that will take place immediately following the closing of the Arrangement and a name change to "Denison Energy Corp.". The share consolidation and the name change will require shareholder approval from two thirds of the votes cast by the holders of Denison common shares.

The Arrangement includes a common share exchange through which Fission common shareholders will receive 1.26 common shares of Denison (each a "Denison Share") for each common share of Fission held plus CAD$0.0001 per share in cash (the "Exchange Ratio"). In the event that the Exchange Ratio would require Denison to issue a number of shares that is greater than the current issued and outstanding shares of Denison, the Exchange Ratio will be adjusted so that the total number of shares to be issued by Denison is equal to the number of issued and outstanding shares of Denison less 100,000 shares. Fission's outstanding options and warrants will be exercisable to acquire Denison shares, after taking into account the Exchange Ratio.

The combined company will be approximately 50% owned by each of Denison's and Fission's existing shareholders on a fully-diluted in-the-money basis. The Exchange Ratio represents a premium of approximately 18% for Fission shares based on the 30 day volume weighted average price of Denison's and Fission's shares on the TSX as at July 3, 2015 (the last trading day before the execution of the Binding Letter Agreement).

Denison's Board of Directors have determined the proposed transaction is in the best interest of Denison and its shareholders, having taken into account the written fairness opinion of Haywood Securities Inc., and have unanimously approved the Arrangement.

The Board of Directors of Fission, acting on the recommendation of its special committee of independent directors, having taken into account the written opinion of Dundee Securities Ltd. dated July 6, 2015, that the transaction is fair, from a financial point of view to Fission securityholders, has determined that the transaction is in the best interests of Fission and has unanimously approved the Arrangement.

Denison and Fission's Board of Directors recommend that their shareholders vote in favour of the Arrangement.

The respective shareholder meetings of Denison and Fission and the closing of the Arrangement are expected to occur in October 2015 or such date as the parties may agree.

In addition to shareholder approvals, the Arrangement is subject to applicable regulatory approvals and the satisfaction of other customary conditions. The Arrangement includes customary provisions, including fiduciary-out provisions, covenants not to solicit other acquisition proposals and the right to match any superior proposals. Each company has agreed to pay the other party a termination fee of CAD$14.0 million in certain circumstances.

Copies of the Arrangement Agreement and certain related documents and agreements are available through Denison's filings with the securities regulatory authorities in Canada at www.sedar.com and the United States at www.sec.gov/edgar.shtml.
