Canadian Reporting Standards

International standards for the reporting of Mineral Resources, Mineral Reserves and Exploration Results have been developing at a rapid pace for the past thirty years due to the globalization of the mining industry. The current Canadian Reporting Standards for Mineral Resources and Mineral Reserves are the Canadian Institute of Mining Metallurgy and Petroleum (CIM) Definition Standards for Mineral Resources and Mineral Reserves, the Canadian stock exchange requirements for disclosure on mineral properties, the CIM Best Practices, and peer-reviewed papers describing industry practice.

CIM Definition Standards

The CIM Definition Standards on Mineral Resources and Reserves (CIM Definition Standards) establish definitions and guidance on the definitions for mineral resources, mineral reserves, and mining studies used in Canada. The Mineral Resource, Mineral Reserve, and Mining Study definitions are incorporated, by reference, into National Instrument 43-101 – Standards of Disclosure for Mineral Projects (NI 43-101). The CIM Definition Standards were initially approved by CIM Council in August 20, 2000 and after various CIM Committees compiled and published more extensive documentation on mining industry standard practices for estimating Mineral Resource and Mineral Reserves were amended in 2005. The current version of the CIM Definition Standards was adopted by CIM Council on May 10, 2014.
