Mining


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 (NI 43-101) 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 is to be independent of the company and the property. A company is required to use specified terminology when disclosing resources and reserves.

The BCSC recently published its first Mining Report. The purpose of this report is to summarize the findings of our mining technical disclosure reviews and to provide guidance and discussion on topical NI 43-101 issues that may be of interest to mining issuers.

A qualified person estimating mineral resources or mineral reserves for coal may follow these guidelines:

However, for all disclosure of mineral resources or mineral reserves for coal, issuers are required by section 2.2 of the Instrument to use the equivalent mineral resource or mineral reserve categories set out in the CIM Definition Standards and not the categories set out in Paper 88-21. The CSA believes it is not reasonable to apply Paper 88-21 to foreign coal properties.

NI 43-101: Mandated Filings on SEDAR

back to top

If section 4.1 or 4.2 of NI 43-101 triggers a technical report, you are required to file the following documents in SEDAR:

  • Technical reports(s)
  • Certificates of Qualified Persons (see s.8.1 of NI 43-101)
  • Consents of Qualified Persons (see s.8.3 of NI 43-101)

We remind filers that offering memorandums are not mandated SEDAR filings. We recommend that you file your offering memorandums and reports of exempt distribution using BCSC eServices. Technical reports, along with the certificates and consents of qualified persons, can be filed electronically by including them in one electronic document along with the offering memorandum.
