MONTREAL, QUEBEC--(Marketwired - Jun 30, 2017) - Osisko Gold Royalties Ltd (OR)(OR) ("Osisko" or the "Company") is pleased to announce that it has filed a management information circular (the "Circular") and related proxy materials with the Canadian securities regulators and U.S. Securities and Exchange Commission in advance of its special meeting of shareholders (the "Meeting").

BACKGROUND

On June 5, 2017, Osisko announced that it has entered into a definitive agreement with Orion Mine Finance Group ("Orion") to acquire a high-quality precious metals portfolio of assets consisting of 74 royalties, streams and precious metal offtakes for total consideration of C$1.125 billion, creating a growth-oriented, world class and gold-focused royalty and streaming company (the "Transaction").

The combination of Osisko's and Orion's portfolios will result in Osisko holding a total of 131 royalties, streams and precious metal offtakes, including 16 revenue-generating assets. The Company's cornerstone assets remain the 5% net smelter return ("NSR") royalty on the world class and long-life Canadian Malartic gold mine (Canada's largest producing gold mine) and its 2.0% to 3.5% sliding scale NSR royalty on the world class Éléonore gold mine. Through the Transaction, Osisko will gain a 9.6% diamond stream on the Renard diamond mine and a 4% gold and silver stream on the Brucejack gold and silver mine, all of which are new high-quality mines in Canada, in addition to a 100% silver stream on the substantial Mantos Blancos copper mine in Chile. Certain assets in the Orion portfolio are subject to buyback and buydown provisions.
