Exhibit 99.30

MINE SAFETY DISCLOSURE

Osisko Development Corp. (the “Company”) is committed to the health and safety of its employees and in providing an incident free workplace. The Company maintains a comprehensive health and safety program that includes extensive training for all employees and contractors, emergency response preparedness, site inspections, incident investigation, regulatory compliance training and process auditing.

The Company’s U.S. mining operations are subject to Federal Mine Safety and Health Administration (“MSHA”) regulation under the U.S. Federal Mine Safety and Health Act of 1977 (“FMSH Act”). MSHA inspects the Company’s U.S. mines on a regular basis and may issue various citations and orders if it believes a violation has occurred under the FMSH Act. Whenever MSHA issues a citation or order, it also generally proposes a civil penalty, or fine, related to the alleged violation.

The following disclosures are provided pursuant to Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 16 of General Instruction B to Form 40-F, which require certain disclosures by companies required to file periodic reports under the Securities Exchange Act of 1934 that operate mines regulated under the FMSH Act. The disclosures reflect the Company’s U.S. mining operations only, as such requirements do not apply to the Company’s mines operated outside the United States.

The information in the table below relates to the Company’s U.S. mining operations during the year ended December 31, 2023, as reflected in the Company’s records. In some cases, the data in the Company’s internal systems may not match or reconcile with the data MSHA maintains on its public web site:
