Osisko Receives Proceeds of C$159.4 Million from Pretium and Announces Debt Repayment and Approval for up to C$100 Million in Share Repurchases

(Montréal, December 19, 2018) Osisko Gold Royalties Ltd (“Osisko” or the “Company”) (OR: TSX & NYSE) is pleased to announce that Osisko Bermuda Limited (“OBL”), a wholly owned subsidiary of Osisko, has received proceeds of US$118.5 million (approximately C$159.4 million) from Pretium Exploration Inc., a subsidiary of Pretium Resources Inc. (collectively “Pretium”) in regards to the closing of Pretium’s exercise of its option to fully repurchase OBL’s interest in the Brucejack gold and silver stream, as provided for in the purchase and sale agreement between the parties dated September 15, 2015 (the “Stream Repurchase”).

Osisko expects to use the proceeds from the Stream Repurchase to repay outstanding amounts of approximately C$58 million under the revolving credit facility and to fund share repurchases as part of its previously announced normal course issuer bid (the “NCIB”). Following the above-mentioned debt repayment, Osisko will have approximately C$30 million outstanding on its revolving credit facility.

Sean Roosen, Chair and Chief Executive Officer of Osisko commented: “Given the current market conditions and based on the confidence we have in the strength of our business and the quality of our assets, we believe the Company’s shares are an attractive investment opportunity and are prepared to deploy up to C$100 million towards our share buyback program.”

The actual number of common shares that may be purchased and the timing of such purchases will be determined by the Company. Decisions regarding purchases will be based on market conditions, share price, best use of available cash and other factors. Any securities acquired under the NCIB of the Company will be cancelled.

The Stream Repurchase does not affect Osisko’s 2018 gold equivalent ounce production guidance of 77,500 to 82,500 gold equivalent ounces. Osisko continues to retain exposure to the Brucejack mine through its 50% gold offtake interest.
