Whistleblowing Policy3

Osisko Development advocates for a zero-tolerance policy towards retaliation against whistleblowers. Osisko Development provides anonymous channels as well as other avenues for any person, whether internal or external to our operations, to report any concerns, misconduct, or suspected violations of any applicable laws, regulations, or any of Osisko Development’s policies. The channels through which reports can be made include a hotline which can be accessed online or via telephone. The Whistleblowing Policy:

Contractual terms and conditions

Potential supply chain risks of forced labour or child labour

Osisko Development recognizes that the risk of forced labour and child labour is greater within our supply chains compared to our own operational activities. Furthermore, certain individuals, sectors, and geographic locations within our supply chains may be at higher risk of forced labour and child labour.

As such, the Company has identified the following categories of goods as being the most notable potential risks of forced labour and child labour within our supply chains:

· mining equipment and associated inputs which may be sourced from a variety of jurisdictions and suppliers;

· other goods manufactured in regions considered at higher-risk of forced labour or child labour; and

· clothing and personal protective equipment.

The measures Osisko Development takes to mitigate the risk of forced labour and child labour in our operations include our policies and procedures outlined above, in addition to other risk management strategies.

Remediation measures and loss of income

In 2023, Osisko Development did not implement any remediation measures as no instances of forced labor or child labor were identified in our operations or supply chains.
