/NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES /

Marathon Gold Corporation ("Marathon" or the "Company") (MOZ.TO) and Mountain Lake Resources Inc. ("Mountain Lake") (MOA.V) today announced the signing of a binding arrangement agreement (the "Arrangement"), whereby Marathon will acquire all of the outstanding common shares of Mountain Lake. The transaction will consolidate Marathon's and Mountain Lake's respective 50% interests in the Valentine Lake Project in Newfoundland, Canada , resulting in Marathon becoming the 100% owner of the project. Mountain Lake's remaining projects will be transferred to Mountain Lake Minerals Inc. ("Spinco"), a newly incorporated exploration company.

Under the terms of the Arrangement, Mountain Lake shareholders will receive 0.40 of a Marathon common share (the "Share Consideration") and 0.40 of a common share of Spinco (the "Spinco Consideration") for each Mountain Lake common share held. The Share Consideration for the purchase of 100% of the issued and outstanding shares of Mountain Lake is approximately $15.1 million , not including the value of Spinco.

Transaction Highlights

    The Share Consideration values Mountain Lake at $0.30 per share, representing a 20% premium to Mountain Lake's pre-announcement closing price on May 23, 2012 and a 20.6% premium based on the 10-day volume weighted average prices of each company, excluding the value of Spinco

    Consolidates Marathon's ownership of the Valentine Lake Project in Newfoundland, bringing its total Measured and Indicated Resource to 424,000 ounces of gold at 2.05 g/t and total Inferred Resource to 305,000 ounces of gold at 1.65 g/t

    Allows exploration at the Valentine Lake Project to be aggressively pursued under one consolidated owner

    Enhances Marathon's capital markets profile as the 100% owner of its flagship asset

    Allows Mountain Lake shareholders to participate in the upside of a consolidated Valentine Lake Project as well as Marathon's Golden Chest Mine project, while maintaining an equity interest in Spinco's exploration portfolio

"We are very pleased that the arrangement agreement has been signed and look forward to the Mountain Lake shareholders approving the completion of this transaction. With 100% ownership of the Valentine Lake Project and a 50% interest in the Golden Chest Mine, Marathon will now boast 497,500 ounces of gold at a grade of 1.94 g/t in the Measured and Indicated category and 421,650 ounces of gold at a grade of 1.59 g/t in the Inferred category. This strategic acquisition exemplifies Marathon's commitment to building shareholder value by moving the company closer to the million ounce Resource threshold," said Phillip Walford , President and CEO of Marathon Gold.

As part of the Arrangement, Mountain Lake will transfer all of its projects, except for the Valentine Lake Project, to Spinco. Spinco will be led by the existing management team and Board of Directors of Mountain Lake and will focus on developing its promising exploration properties, including the Glover Island, Little River, and Bobby's Pond projects. Pursuant to the Arrangement, (i) Marathon will subscribe for units of Spinco for aggregate consideration of $300,000 representing approximately 6.2% of the outstanding shares of Spinco, and (ii) the directors and officers of Mountain Lake will collectively subscribe for an additional $360,000 of units of Spinco representing 7.4% of the outstanding shares of Spinco. At the closing of the Arrangement, it is expected that current Mountain Lake shareholders will hold the remaining 86.4%.

The Arrangement has been approved unanimously by the Board of Directors of both Marathon and Mountain Lake. Directors and officers of Mountain Lake have entered into lock-up agreements with Marathon under which they have agreed to vote their Mountain Lake shares and options in favour of the Arrangement, representing approximately 7.1% of the shares and options entitled to vote at the Mountain Lake special meeting.

The Board of Directors of Mountain Lake has received a fairness opinion from Stephen Semeniuk that the Share Consideration is fair, from a financial perspective, to the shareholders of Mountain Lake.

The acquisition of Mountain Lake by Marathon is expected to be completed by way of a court approved plan of arrangement in British Columbia. All Mountain Lake stock options outstanding on the effective date of the Arrangement will be cancelled. Mountain Lake warrants will be adjusted on their own terms to entitle their holders to acquire common shares of Marathon and Spinco. The transaction is targeted to close in July 2012 .

The completion of the Arrangement will be subject to, among other things, (i) the favourable vote of 66 2/3% of the votes cast by Mountain Lake shareholders and option holders voting as a single class at a special meeting called to approve the transaction which is expected to take place in July 2012 , and (ii) the favourable vote of a majority of the votes cast by Marathon shareholders at a special meeting called to approve the issuance of the Marathon shares pursuant to the Arrangement.

In the event that the Arrangement is not completed, there are certain circumstances under which either Marathon or Mountain Lake may be entitled to receive a termination fee from the other party, which can be up to a maximum amount of $500,000 . Mountain Lake has also provided Marathon with certain other customary rights, including a right to match competing offers.
