Osisko Development Proposes Name Change to Osisko Gold Group Inc.

Osisko Development Corp. is proposing to change its corporate name to Osisko Gold Group Inc. at its upcoming annual and special meeting of shareholders. The company also announced the nomination of Keith McKay to its board of directors, signaling a strategic shift for the mining firm.

These developments follow a period of significant financial activity for Osisko. In May 2026, the company closed a US$225 million offering of convertible senior notes, followed by an additional US$75 million closing. Earlier in May, it had priced a US$275 million offering of convertible notes. In January 2026, Osisko completed a US$125 million bought deal public offering of common shares to advance its Cariboo Gold Project.

The company has also been active in operational and project development. In February 2026, Osisko awarded a contract for project and construction management services for the Cariboo Gold Project. Site activities at Cariboo were also set to resume in March 2026. In January 2026, the company finalized the sale of its San Antonio Gold Project.

The proposed name change to Osisko Gold Group Inc. suggests a renewed focus on gold assets and strategic growth within the sector as the company continues to advance its key projects and potential developments.
