CSA Staff Notice 43-311: Review of Mineral Resource Estimates in Technical Reports
The Canadian Securities Administrators published this notice to present findings from a review of 86 technical reports, identifying specific areas where mineral resource estimate disclosures were non-compliant or inadequate. The review highlights deficiencies in demonstrating reasonable prospects for eventual economic extraction, verifying legacy data, disclosing project-specific risks, and reporting cut-off grade sensitivities. Issuers are required to correct material disclosure deficiencies by amending and refiling technical reports, while Qualified Persons are advised to adhere to these standards to ensure transparency and regulatory compliance.
