International Reporting
Template

The International Reporting Template (IRT) is a document that draws on the best of the CRIRSCO-style reporting standards, such as the JORC Code (Australasia), SAMREC Code (South Africa), PERC Reporting Standard (Europe), CIM Guidelines (Canada), SME Guide (USA) and Certification Code (Chile). These reporting standards are recognised and adopted world-wide for market-related reporting and financial investment.

CRIRSCO formed an alliance in 2007 with the International Council for Mining and Metals and became a Task Force of that organisation charged with promoting and maintaining best practice reporting. In October 2009, CRIRSCO became a Strategic Partner of ICMM.
