TORONTO, ONTARIO--(Marketwire - Aug. 7, 2012) - Avion Gold Corporation ("Avion") (TSX:AVR)(OTCQX:AVGCF) is pleased to announce today that it has entered into a definitive arrangement agreement (the "Arrangement Agreement") with Endeavour Mining Corporation ("Endeavour"), pursuant to which Endeavour has agreed to acquire all of the issued and outstanding common shares ("Avion Shares") of Avion by way of a statutory plan of arrangement under the Business Corporations Act (Ontario) (the "Arrangement").

Under the terms of the Arrangement Agreement, each Avion shareholder will receive 0.365 (the "Exchange Ratio") of an ordinary share of Endeavour for each Avion Share held. Each shareholder of Avion that is a Canadian resident may elect for tax purposes to receive Avion Exchangeable Preferred Shares ("Exchangeable Shares") on the basis of the Exchange Ratio. Each Exchangeable Share will be exchangeable for one ordinary shares of Endeavour at the option of the holder (the "Arrangement").

Based on the closing price of the Endeavour Shares on the Toronto Stock Exchange (the "TSX") of $2.40 on August 7, 2012, the last trading day prior to the announcement of the Arrangement, the share consideration represents a 56.4% premium to the closing price of Avion Shares and a 70% premium over the volume-weighted average trading price ("VWAP") of the Avion Shares on the TSX for the last 20 trading days, on a VWAP to VWAP basis. On a pro-forma basis, Avion's shareholders are expected to hold approximately 39.8% of Endeavour on completion of the Arrangement.

John Begeman, President, CEO and Director of Avion, states "We are very pleased with the proposed transaction as it provides our shareholders with a substantial premium and meaningful ownership in a stronger combined West African-focused mining company with the financial resources to withstand a protracted lull in the capital markets. We believe this transaction to be mutually beneficial to both parties and strategically positions the new company well for future value creation. I look forward to my new role as a director of the new, stronger company."

Transaction Details

The completion of the Arrangement is subject to customary conditions, including receipt of all necessary court, shareholder and regulatory approvals. The Arrangement Agreement includes customary representations and warranties of each party, non-solicitation covenants by Avion, "right-to-match" provisions in favour of Endeavour in the event of a Superior Proposal (as defined in the Arrangement Agreement) and the payment by Avion to Endeavour of a termination fee in the amount of $11,500,000 should the Arrangement Agreement be terminated in certain circumstances.

The Arrangement is subject to the approval of 66 2/3% of the votes cast at a special meeting of Avion's shareholders to approve the arrangement (the "Avion Meeting") that is expected to occur on or about October 12, 2012. An information circular regarding the Arrangement will be filed with regulatory authorities and mailed to Avion's shareholders in accordance with applicable securities laws. The record date for the special meeting of the Avion's shareholders will be announced in the near future.

The issue of the Endeavour ordinary shares pursuant to the Arrangement must be approved by a simple majority of the shareholders of Endeavour at a special meeting of Endeavour shareholders (the "Endeavour Meeting"). The Endeavour Meeting is expected to occur on the same date as the Avion Meeting.

The Board of Directors of the combined company will draw from the expertise of both companies. John Begeman and another member of the current Avion board will be joining Endeavour's Board.

Exchangeable Loan

Avion and Endeavour have also entered into a loan agreement (the "Loan Agreement") whereby Endeavour is providing a US$20,000,000 exchangeable loan (the "Loan") to Avion Resources (Mali) Ltd (the "Borrower"), a wholly-owned subsidiary of Avion. The Loan is for an initial term of six months (the "InitialMaturity Date") and bears interest at the rate of LIBOR plus 6%. Pursuant to the terms of the Loan Agreement, Avion has agreed to guarantee the Loan, which is secured against the common shares in the capital of the Borrower and Avion Mali Limited, another wholly-owned subsidiary of Avion.

The Loan is exchangeable at the option of Endeavour, at any time subsequent to the advance of the Loan, into Avion Shares at an exchange price of US$0.4323 per Avion Share. In certain circumstances Avion will have the option to exchange the Loan for Avion Shares on the Initial Maturity Date at the lower of the agreed conversion price of US$0.4323 per Avion Share and the five day VWAP of the Avion Shares on the TSX as at the close of trading on the date immediately preceding the Initial Maturity Date. Endeavour will, in turn, have the right to elect not to allow the conversion of the Loan at that time but instead to have the Loan remain outstanding for an additional six months on the same terms, subject to Endeavour retaining the option to convert at any time at the lower of the agreed upon conversion price of US$0.4323 per share and the five day VWAP of the Avion Shares on the TSX as at the close of trading on the date immediately preceding the initial repayment date. The exchangeability features of the Loan are subject to the approval of the TSX. If the approval of the TSX to these exchangeability features is not obtained, the Loan will bear interest at the rate of LIBOR plus 12%.

The proceeds of the Loan will be used to fund capital expenditures for Avion's Tabakoto mine and general corporate purposes.

Board and Special Committee Approval

The Board of Directors of Avion formed a special committee (the "Special Committee") comprised of Bruce Humphrey, Honourable Pierre Pettigrew P.C. and Bernie Wilson to consider the proposed Arrangement. The Special Committee, based in part on a fairness opinion from National Bank Financial Inc. that the consideration offered in the Arrangement is fair to the holders of Avion Shares from a financial point of view, has unanimously determined that the completion of the Arrangement is in the best interests of Avion. The Special Committee unanimously recommended that the Board of Directors approve the Arrangement and recommend that shareholders of Avion vote in favour of the Arrangement.

Based in part on the recommendation of the Special Committee and on a fairness opinion from GMP Securities L.P. that the consideration offered in the Arrangement is fair to the holders of Avion Shares from a financial point of view, the Board of Directors of Avion determined that the Arrangement is in the best interests of Avion and Avion's shareholders. The Board recommends that Avion's shareholders vote to approve the Arrangement at the Avion Meeting.
