Osisko Gold Royalties' History Osisko Gold Royalties is a spin-off company that was incorporated on April 29, 2014. Its creation was part of a deal between Osisko Mining, Yamana Gold and Agnico Eagle Mines in which white knights Yamana and Agnico purchased Osisko Mining, thwarting Goldcorp's hostile takeover bid. While Yamana and Agnico each retained 50% ownership of Osisko Mining's Malartic mine, Osisko Gold Royalties was spun-off with a 5% net smelter return on the mine, a 2% net smelter return on several Agnico and Yamana mines in the Kirkland Lake area of Ontario, plus CAN$157 million cash for building the company up by making acquisitions, and with Osisko Mining CEO Sean Roosen continuing as Osisko Gold Royalties' CEO.
