The Mineral Resources and Mineral Reserves (MRMR) Committee develops and defines the standards, best practices and guidelines that are intended to foster greater standardization of reporting within the public domain, specifically under NI 43-101. These standards provide a benchmark for both companies and Qualified Persons in discharging their responsibilities. MRMR’s mandate includes maintaining and updating of the standards and guidelines, including the Industrial Minerals Best Practice Guidelines (“IM BP Guidelines”), and to undertake a program of industry and CIM member consultation prior to submitting updates to CIM Council for approval.

The current version of the IM BP Guidelines was accepted by the CIM Council on November 23, 2003. Over the past several years the MRMR Committee has carried out a review and proposed update of the IM BP Guidelines. The proposed changes to the IM BP Guidelines reflect current views of leading practices in respect of the preparation of Mineral Resource and Mineral Reserve estimates for industrial mineral deposits.

The MRMR Committee is circulating a draft of the proposed changes and updates to the IM BP Guidelines and is soliciting public review and comment. Copies of the draft version of the proposed updated document in PDF format are available for downloading and review here.

Interested parties are invited to submit comments and suggestions by Friday, April 14, 2023.
