The BC Securities Commission (BCSC) regulates more than 65 per cent of the reporting mining issuers in Canada. Mining and mineral exploration companies in Canada must follow specific guidelines for disclosure, designed to improve the accuracy and integrity of the information they provide. National Instrument 43-101, Standards of Disclosure for Mineral Projects, governs a company's public disclosure of scientific and technical information about its mineral projects.

National Instrument 43-101 Standards of Disclosure for Mineral Projects

This instrument governs disclosure, including oral statements, written documents and websites. The disclosure must be based on information provided by a "qualified person" (as defined in NI 43-101). NI 43-101 requires a company to file a technical report at certain times, prepared in a prescribed format. In some circumstances, the qualified person must be independent of the company and the property. A company is required to use specified terminology when disclosing resources and reserves.

Mining FAQs

If a resource issuer fails to file a technical report triggered under NI 43-101, Standards of Disclosure for Mineral Products, the issuer may:

  • not be able to use exemptions available under securities legislation
  • appear in default on the Reporting Issuers List
  • be Cease Traded without notice
  • not be able to complete any prospectus financing until it files the required report.

The issuer may also face other remedial enforcement actions. 

If your company is a mining or exploration company, you must file a current technical report (Form 43-101F1) for each of the mineral properties that are material to your company. You must file the technical reports at the same time you file or make the offering memorandum available to the public in Canada. If you previously filed a technical report that is still current, you do not have to file a new technical report. If you have any questions on technical reports, contact us.
