The PERC Standard for Reporting of Exploration Results, Mineral Resources and Mineral Reserves (the ‘PERC Reporting Standard’) [1] sets out the minimum standards, as well as additional guidelines and recommendations for the Public Reporting of Exploration Results, Mineral Resources and Mineral Reserves within Europe.
It applies to all solid mineral raw materials for which Public Reporting of Exploration Results, Mineral Resources and Mineral Reserves is required by any relevant regulatory authority.
The PERC Reporting Standard is fully aligned with the CRIRSCO International Reporting Template.[2]
The CRIRSCO International Reporting Template [2] is a document that represents the best of the CRIRSCO-style codes for the public reporting of Exploration Results, Mineral Resources and Mineral Reserves that are recognised and adopted world-wide for market-related reporting and financial investment.
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. Details of the relationship between the two systems are provided in the CRIRSCO Template to UNFC Bridging Document [3] which was originally published in 2015 and since updated in 2024 to reference the 2019 versions of both systems (UNECE, 2024). Additional guidance for users of the bridging document is provided in an accompanying guidance note (CRIRSCO and UNECE, 2024 [4]).
