On June 12, 2025, the Canadian Securities Administrators ("CSA") published Notice and Request for Comment – Proposed Repeal and Replacement of National Instrument 43-101 Standard of Disclosure for Mineral Projects (the "Notice"), describing the CSA's proposal to repeal and replace the current National Instrument 43-101 Standards of Disclosure for Mineral Projects (the "Instrument"), Form 43-101F1 Technical Report (the "Form"), and Companion Policy 43-101CP to the Instrument (the "Companion Policy").

While the majority of the proposed amendments to the Instrument, Form, and Companion Policy (the "Proposed Amendments") relate to codifying current practices and making minor changes, certain aspects of the Proposed Amendments may require issuers to change their current practices. The CSA has opened a 120-day comment period ending October 10, 2025, with respect to the Proposed Amendments.
