The Canadian Securities Administrators (CSA) is undertaking a significant overhaul of National Instrument 43-101 – Standards of Disclosure for Mineral Projects (the Instrument), Form 43-101F1 – Technical Report (the Form) and the related Companion Policy 43-101CP (the Companion Policy). On February 13, 2025, the British Columbia Securities Commission released BC Notice 2025/01 (the Notice) providing an update on the process. The Notice included near-final drafts of these updates, collectively referred to as the Modernized Disclosure Requirements. These drafts were provided on an information-only basis and were not released as part of a request for comments. A formal CSA Notice and Request for Comment is expected in the coming months.
