Osisko Mining Announces Corporate Governance Changes in Advance of Upcoming Shareholders' Meeting

TORONTO, June 22, 2018 (GLOBE NEWSWIRE) -- Osisko Mining Inc. (TSX:OSK) ("Osisko" or the "Corporation") today announces certain corporate governance changes on account of recommendations made by Institutional Shareholder Services in the course of their review of the matters to be voted on at the upcoming annual and special meeting of shareholders of Osisko to be held on June 29, 2018 (the "Meeting").

In particular, the stock option plan of the Corporation (the "Stock Option Plan") and certain other equity incentive amendments are being made or clarified as follows:

• All awards under the Stock Option Plan (and all other forms of equity compensation) are subject to Osisko's "Policy on Recoupment of Incentive Compensation" adopted on April 27, 2017 (the "Clawback Policy"). The Clawback Policy has no restrictions relating to when awards were granted. The full text of the Clawback Policy is available for review by shareholders on Corporation's website at https://www.osiskomining.com/.
   
• Consistent with evolving corporate governance best practices in Canada, the 500,000 options awarded to Mr. John Burzynski, Chief Executive Officer of Osisko, on January 11, 2018, with an exercise price of $3.46, have been amended to vest in equal tranches over a five-year period. These 500,000 options were scheduled to vest (or, in part, have vested) in three equal tranches on January 11, 2018, 2019 and 2020, and have been amended to vest in five equal tranches on January 11, 2019, 2020, 2021, 2022 and 2023.
   
• Consistent with seeking greater alignment between stock performance and Chief Executive Officer total compensation, Mr. Burzynski, Chief Executive Officer of Osisko, is being awarded 25,000 restricted share units in consideration of the option amendments described above. These 25,000 restricted share units cliff vest after three years, and are subject to the achievement of performance-based criteria relating to asset development, financial performance, shareholder returns and sustainability.
