Gold Fields Completes Acquisition of Osisko Mining

TORONTO, Oct. 25, 2024 (GLOBE NEWSWIRE) --  Osisko Mining Inc. ("Osisko") (TSX:OSK) is pleased to announce the successful completion of its previously announced plan of arrangement transaction (the "Arrangement"), pursuant to which, among other things, Gold Fields Limited, through a 100% owned Canadian subsidiary, Gold Fields Windfall Holdings Inc., acquired all of the issued and outstanding common shares of Osisko (the "Shares").

Osisko's Chairman and Chief Executive Officer, John Burzynski, commented:

"This premium transaction represents a strong and near-term outcome for our shareholders and is reflective of the truly world class nature of the Windfall Project. In the span of nine years, we've transformed Windfall into one of the largest and highest-grade gold development projects globally, and this transaction is a testament to the extraordinary entrepreneurial effort of the Osisko Mining team. Gold Fields is a globally diversified senior gold producer with an impressive track record of successfully building and operating mines. As our (now former) joint venture partner at Windfall, Gold Fields knows the asset well and understands the significance of the strong relationships that we have built in Québec with all of our stakeholders. Moreover, Gold Fields share our core principles of operating in a safe, inclusive and socially responsible manner. They are well suited to take Windfall into production and we wish them all the best going forward."

Under the terms of the Arrangement, each former shareholder of Osisko is entitled to receive C$4.90 for each Share (the "Consideration") held immediately prior to the effective time of the Arrangement. A Final Order approving the Arrangement was granted by the Ontario Superior Court of Justice on October 22, 2024. The Arrangement became effective earlier today.
