PERC Reporting Standard

The CRIRSCO Template family of reporting codes and standards is complementary to the United Nations Framework Classification for Resources (UNFC) which was initially developed in 1997 to support the development of mineral inventories by government organisations but has since been expanded to cover a range of other sectors.

The CRIRSCO Template has been endorsed by the UNECE’s Expert Group on Resource Management as a UNFC Aligned System for use in classifying estimates for minerals projects.

The Australasian 'Joint Ore Reserves Committee - JORC[5] was formed in 1971 because of concerns about the increase in unacceptable reporting practices (e.g. Poseidon Bubble).

During the 1990s, it became clear that the evaluation of mineral deposits should be based on an internationally recognised code of reporting in order to improve the security of investments in this economic sector (e.g. Bre-X case).

In 1994, a global representative body, now the 'Combined Reserves International Reporting Standards Committee' - CRIRSCO,[6] was formed to create a set of standard international definitions for reporting mineral resources and mineral/ore reserves, modelled on the JORC[5] Code.

Solid raw materials include (but are not limited to): The Standard is binding on the individual members of the Participating Organisations.

National Instrument 43-101, the legislation which specifies 'Standards of Disclosure' for Mineral Projects within Canada, is broadly comparable to the CRIRSCO reporting codes and standards.
