Osisko Announces Renewal of Normal Course Issuer Bid

TORONTO, Dec. 28, 2018 (GLOBE NEWSWIRE) -- Osisko Mining Inc. (TSX:OSK) (the "Corporation" or "Osisko") today announces renewal of the normal course issuer bid program of the Corporation to purchase for cancellation, from time to time over a 12-month period, common shares of the Corporation ("Common Shares") listed on the Toronto Stock Exchange ("TSX") in an aggregate amount of up to 10% of the "public float" of the Corporation (the "NCIB Program"), being 14,251,609 Common Shares.

Repurchases under the NCIB Program may commence on January 2, 2019 and will terminate on January 1, 2020 or on such earlier date as the NCIB Program is complete. Purchases of Common Shares under the NCIB Program will be made in Canada through the facilities of the TSX in accordance with its rules. Daily purchases will be limited to 208,038 Common Shares, other than block purchase exemptions, representing 25% of the average daily trading volume of the Common Shares on the TSX for the six month period ending November 30, 2018, being 832,152 Common Shares.

The price that the Corporation may pay for any Common Shares purchased under the NCIB Program will be the prevailing market price at the time of purchase and any Common Shares purchased by the Corporation will be cancelled. The actual number of Common Shares repurchased under the NCIB Program and the timing of such repurchases will be at Osisko's discretion and shall be subject to the limitations set out in the TSX Company Manual.

The board of directors of Osisko believes that the underlying value of the Corporation may not be reflected in the market price of the Common Shares from time to time and that, accordingly, the purchase of Common Shares will increase the proportionate interest in the Corporation of, and be advantageous to, all remaining shareholders of the Corporation.

As of December 27, 2018, there were 257,189,331 Common Shares issued and outstanding, and the Corporation had a public float of 142,516,096 Common Shares.

Osisko has appointed BMO Nesbitt Burns Inc. to make any purchases under the NCIB Program on its behalf. The commencement of the NCIB Program is subject to TSX approval.

During the prior NCIB Program of the Corporation, which commenced on December 29, 2017 and will terminate on December 28, 2018, Osisko had approval to acquire up to 15,204,587 Common Shares, but nil Common Shares were acquired.
