Osisko Gold Royalties Ltd Launches Osisko Development Corp. And Announces Related Corporate Changes

Closing of RTO

Earlier today Osisko Royalties and Osisko Development completed their previously announced spin-out transaction, which resulted in, among other things, Osisko Royalties transferring certain mining properties, including the Cariboo Gold Project, and a portfolio of marketable securities (through the transfer of the entities that directly or indirectly own such mining properties and marketable securities) to Osisko Development Holdings Inc. ("Osisko Subco"), following which Osisko Subco and 1269598 BC Ltd. ("Barolo Subco") were amalgamated by way of a triangular amalgamation under the Business Corporations Act (British Columbia) (the "Amalgamation") to form "Amalco". Upon the Amalgamation, Osisko exchanged its Osisko Subco shares for ODV Shares, which resulted in a "Reverse Take-Over" of Osisko Development (the "RTO").

Each common share purchase warrant of Osisko Subco outstanding immediately prior to the effective time of the Amalgamation was exchanged for one common share purchase warrant of Osisko Development, with each common share purchase warrant of Osisko Development entitling the holder to acquire one ODV Share at a price of CDN $10 per share for a period of 18 months from the effective date of the Amalgamation.
