Osisko Gold Royalties announces agreement to acquire royalty rights from Oban Mining Corporation

(Montréal, June 9, 2015)  Osisko Gold Royalties Ltd (the “Corporation” or “Osisko”) (OR: TSX) today announces that it has entered into an agreement to purchase up to 181,818,181 common shares (the “Purchased Shares”) of Oban Mining Corporation (“Oban”) at a price of $0.11 per share, for an aggregate purchase price of up to $20 million (the “Transaction”). The Purchased Shares will be acquired by Osisko in connection with the completion of certain transactions announced by Oban earlier today (the “Proposed Oban Transactions”). The completion of the Transaction is subject to the satisfaction of certain conditions precedent, including that Osisko holds no more than 19.9% on a non-diluted basis of the issued and outstanding common shares of Oban. The number of Purchased Shares to be acquired by Osisko may be reduced to the extent that any of the Proposed Oban Transactions are not completed.

The financing commitment includes the grant to Osisko of first rights to participate in royalties and streams created by Oban following the Proposed Oban Transactions and pro rata financing participation rights. For a period of five years from the date of closing of the Transaction, Osisko will have a one-time right, should Oban seek financing in debt or equity markets, to provide first financing to Oban equal to $5 million in exchange for the granting by Oban of a 1% NSR over such properties as are wholly owned by Oban immediately following completion of the Transaction.

Following the closing of the Transaction, Osisko will be entitled to nominate three directors who will be put forward and included in management’s nominees for directors at any meeting of Oban shareholders, as long as Osisko holds at least 10% of the issued and outstanding common shares of Oban on a non-diluted basis.

Investment

Other than 1,910,828 common shares of Oban previously held by Osisko (the “Prior Holdings”), neither Osisko, nor any other person acting jointly or in concert with Osisko, previously held any other securities of Oban.  If Osisko acquires 181,818,181 Purchased Shares (which, for greater certainty, assumes that all of the Proposed Oban Transactions are completed), it would own a total of 183,729,009 common shares of Oban, which would represent approximately 19.9% of the total issued and outstanding common shares of Oban (on a partially-diluted basis assuming all of the Proposed Oban Transactions are completed). To the extent that any of the transactions announced by Oban earlier today are not completed, the subscription by Osisko may be reduced to ensure that Osisko never holds more than 19.9% of the issued and outstanding common shares of Oban.

Osisko intends to hold the Purchased Shares and the Prior Holdings for investment purposes. Other than the Purchased Shares and the Prior Holdings, Osisko has no current intention to increase the beneficial ownership of, or control or direction over, additional securities of Oban.

Osisko will file an Early Warning Report containing further details of the acquisition of the Purchased Shares on SEDAR at www.sedar.com under Oban’s profile.
