Proposed repeal and replacement of NI 43-101: Standards of Disclosure for Mineral Projects: Update

On June 12, the Canadian Securities Administrators published a proposed replacement of National Instrument 43-101 Standards of Disclosure for Mineral Projects and its related companion policy and form of technical report, along with a notice and request for comment and proposed consequential amendments to various instruments and forms (the Proposal). The Proposal is open for comment until October 10, 2025.

The Proposal is intended to update and enhance the CSA’s current mineral disclosure requirements to provide investors with more relevant and improved disclosure, while continuing to foster fair and efficient capital markets for mining issuers. The Proposal was originally issued informally before PDAC 2025 to allow industry participants an opportunity for discussion.
