RETRANSMISSION: Champion Enters Into Arrangement Agreement With Mamba

TORONTO, ONTARIO -- (Marketwired - Dec 6, 2013) - Champion Iron Mines Ltd. (TSX:CHM) (FRANKFURT:P02) ("Champion" or the "Company") is pleased to announce that Champion and Mamba Minerals Limited (ASX:MAB) ("Mamba") have entered into a definitive arrangement agreement (the "Agreement") pursuant to which Mamba, together with a wholly-owned Canadian subsidiary of Mamba ("Canco") will acquire, by way of a court-approved plan of arrangement (the "Arrangement"), all of the outstanding common shares of Champion.

The business combination once completed will create a new iron ore company to be named "Champion Iron Limited" with a significant holding in one of the world's leading iron ore regions and a team of management and directors with a track record for attracting strategic investment into major resource projects. The resulting company will continue to be listed on the Australian Stock Exchange ("ASX") and it is a condition of closing of the Arrangement that Mamba's shares be listed for trading on the Toronto Stock Exchange ("TSX") as of the effective date, thereby providing it access to both the North American and Australian markets.


Transaction Highlights

• Champion shareholders will be entitled to receive 11 ordinary shares of Mamba ("Mamba Shares") in exchange for every 15 common shares of Champion (the "Exchange Ratio")
• Certain Champion shareholders who are Canadian residents will also have the option to receive all or a part of their consideration in the form of exchangeable shares ("Exchangeable Shares") of Canco in place of the Mamba Shares in order to allow such shareholders to defer recognition of capital gains. Each Exchangeable Share will be exchangeable, at no additional consideration, into one Mamba Share
• The offer values Champion at approximately C$0.39 per share or C$59.8 million on a fully diluted in-the-money basis as at December 5, 2013
• Based on the 20 day volume weighted average price ("VWAP") for the period ending December 5, 2013 for Mamba and Champion of A$0.52 and C$0.21, respectively, the offer represents a premium to Champion shareholders of 72%
• Upon completion of the Arrangement, Champion shareholders will own approximately 50.5% of Mamba's pro forma issued share capital on a fully diluted in-the-money basis
• Mamba will undertake an equity financing of at least A$10 million to be completed immediately following the effective date of the Arrangement at a price of no less than A$0.50/share
• The pro forma company will have a cash balance of approximately C$25 million
• Closing of the transaction is subject to regulatory approvals and is expected in April 2014

Concurrent Equity Financing

Mamba will undertake an equity financing ("Concurrent Financing") based on the combined strengths of Champion and Mamba, which will serve to strengthen the combined company's balance sheet and provide financial flexibility with its development plans. It is a condition to the Arrangement that irrevocable firm commitments acceptable to both parties for at least A$10 million be secured by Mamba prior to the effective date of the Arrangement at no less than A$0.50/share. The Concurrent Financing is intended to close immediately after the effective date of the Arrangement.

Capital Investment Partners has been mandated by Mamba to raise the A$10 million via a private placement to selected strategic institutional investors. Funds raised will assist the company to complete a bankable feasibility study ("BFS") on the Consolidated Fire Lake North Project, which will include additional infill drilling and working capital.

Transaction Benefits for Champion Shareholders

• Strengthened balance sheet: The Arrangement and concurrent equity raise will strengthen the combined company's balance sheet as well as provide sufficient funding for the completion of the BFS on the Consolidated Fire Lake North Project
• Immediate and significant offer premium: Exchange Ratio implies an offer premium to Champion shareholders of 72% based on 20 day VWAP prices of Mamba and Champion
• Addition of key mining executives and directors with a proven track record: Addition of Michael O'Keeffe as Executive Chairman significantly enhances the combined company's ability to bring in institutional and strategic investors as well as the capital required to advance the Fire Lake North Project through construction and commercial production
• Exploration upside from the Snelgrove Lake Project: The Snelgrove Lake Project is a highly prospective iron ore project located in the Labrador Trough with excellent access to infrastructure and the potential for both a hematite and multi-billion tonne magnetite project
• Broadens investor base: Provides the new company access to a larger base of institutional and retail investors in North America, Australia and Asia

Commenting on the Arrangement, Champion's President, CEO and Chairman, Thomas Larsen, said, "This merger represents an excellent opportunity for Champion shareholders to realize immediate and substantial value by exchanging their Champion shares for Mamba shares and yet retain the opportunity to participate in the development of the Consolidated Fire Lake North project. Mr. O'Keeffe and his team at Mamba have an outstanding track record in developing and financing bulk commodity infrastructure projects, and I am excited at the opportunity to work with Mr. O'Keefe to deliver the significant value and potential that we confirmed in the Consolidated Fire Lake North Project."

Mamba's Managing Director, Michael O'Keeffe, said, "The Labrador Trough represents one of the world's leading iron ore regions and I am looking forward to building on the success of Mr. Larsen and his team at Champion who have taken the Consolidated Fire Lake North Project through to prefeasibility. Our immediate focus will be on upgrading the 2013 prefeasibility study to a bankable feasibility study, which is expected to be completed within 12 months. At the same time we will be positioning the merged group to be able to access or develop the infrastructure required to fund and put this project into production, and there is a real opportunity here to join the ranks of Canada's existing iron ore producers."
