Southern Arc to Hold 6.3% of New Premier Canadian Junior Gold Mining Company

VANCOUVER, BRITISH COLUMBIA--(Marketwired - June 10, 2015) - Southern Arc Minerals (TSX VENTURE:SA) ("Southern Arc" or "the Company") is pleased to announce that Eagle Hill Exploration Corporation (TSX VENTURE:EAG) ("Eagle Hill"), in which Southern Arc holds a 26.25% interest, has entered into a significant transaction to create a new mining company focused on the exploration and development of gold properties in Canada's Abitibi Gold Belt.

As announced by Eagle Hill on June 9, Oban Mining Corporation (TSX:OBM) ("Oban") has entered into binding letter agreements providing for the launching of supported take-over bids with each of Eagle Hill, Temex Resources Corp. (TSX VENTURE:TME) ("Temex"), Ryan Gold Corp. (TSX VENTURE:RYG) ("Ryan Gold") and Corona Gold Corporation (CSE:CRG) ("Corona"). Completion of the transactions is subject to Oban obtaining shareholder and Toronto Stock Exchange ("TSX") approval. The combination of these five companies will create a leading Canadian focused gold exploration and development company (herein referred to as "New Oban").

In addition, Oban has agreed, subject to TSX approval, to complete a private placement with Osisko Gold Royalties Ltd. ("Osisko") whereby Osisko will invest up to $20 million in common shares in the capital of Oban ("Oban Shares") at a price of $0.11 per Oban Share (the deemed net asset value per share value of Oban), provided that such investment shall not be for more than 19.9% of New Oban.

New Oban brings together major exploration assets in Ontario and Quebec under experienced management in a well-capitalized vehicle, with over $65 million in cash and a significant global gold resource. Dundee Corporation and Osisko will be key shareholders in New Oban, by virtue of their respective existing holdings in four of the five companies involved in the combination, and Osisko's new investment.

Oban has offered Eagle Hill shareholders 10 Oban Shares in exchange for each common share of Eagle Hill, providing a premium of 258% to the 15-day volume weighted average price ("VWAP") of Eagle Hill on the TSX Venture Exchange ("TSX-V") ending on June 8, 2015. Additionally, each shareholder of Eagle Hill will receive five common share purchase warrants of Oban (each a "Warrant") per common share of Eagle Hill, entitling warrant holders to purchase one Oban share at a price of $0.15 per Oban share for a period of 36 months following the closing date. Oban will make an application to the TSX to list the Warrants.

Southern Arc currently holds 6,258,639 shares in Eagle Hill. Southern Arc's Board of Directors has entered into a lock-up agreement to vote its shares in support of the proposed transaction. If the transaction closes as currently proposed, Southern Arc will hold 62,586,390 shares in New Oban, making Southern Arc one of the largest shareholders, after Osisko and Dundee, with a 6.3% interest in New Oban. Southern Arc will also hold a substantial warrant position, with 31.3 million New Oban warrants exercisable at $0.15 until 36 months from closing, 10 million warrants exercisable at $0.16 until May 8, 2016, 3.8 million warrants exercisable at $0.20 until April 8, 2016, and 24.4 million warrants exercisable at $0.20 until August 14, 2017.

"The combination of Eagle Hill, Oban Mining, Temex Resources, Ryan Gold and Corona Gold will form a prominent junior mining company in Canada, with promising gold assets, a substantial treasury, and a management team with an exceptional track record," said John Proust, Chairman and CEO of Southern Arc. "Eagle Hill's Windfall Lake project, following completion of the Preliminary Economic Assessment in April, stands out as the most advanced and highest-grade deposit in the group.

"Eagle Hill's inclusion as a primary founding company in New Oban further validates Southern Arc's investment strategy. New Oban will have the funding in place to accelerate Windfall Lake's development, and the market recognition of best-in-class management and directors with Osisko and Dundee at the helm. We believe this combination is the best way to create near-term shareholder value for both Southern Arc and Eagle Hill."

The transaction brings together mining industry leaders Sean Roosen and Ned Goodman as Co-Chairs of the new board of directors, together with Patrick F.N. Anderson, John Burzynski, Murray John, Rene Marion, Keith McKay, Jose Vizquerra, Robert Wares and David Christie. Management changes will see the current Chairman of Oban, John Burzynski, appointed President and Chief Executive Officer of New Oban, while Jose Vizquerra, current President and Chief Executive Officer of Oban, will become Senior Vice President and Chief Operating Officer of New Oban. New Oban will be headquartered in Montreal with a Toronto corporate office. Exploration, engineering and administrative services will be provided by Montreal-based Osisko.

In addition, Oban has agreed, subject to TSX approval, to complete a private placement (the "Private Placement") with Osisko whereby Osisko will invest up to $20 million in Oban at a price of $0.11 per Oban Share, provided that such investment shall not be for more than 19.9% of New Oban.

New Oban will have approximately 1,105.9 million common shares outstanding on a post-consolidation basis and will have an estimated market capitalization of approximately $122 million (based on post-consolidation trading price of $0.11/share, which corresponds to the deemed net asset value per share value of Oban agreed for the purposes of the transactions).

Each offer is to be subject to typical conditions including a requirement to obtain 66 2/3% support from the shareholders of each company. Certain of the transactions are cross-conditional, including the requirement by each of Eagle Hill, Corona and Ryan Gold that their acquisitions may only be completed together and with the placement from Osisko also being completed.
