PERC Standard

The PERC Standard for Reporting of Exploration Results, Mineral Resources and Mineral Reserves

PERC Reporting Standard 2021

The PERC Standard for Reporting of Exploration Results, Mineral Resources and Mineral Reserves (the ‘PERC Reporting Standard’) sets out the minimum standards, as well as additional guidelines and recommendations for the Public Reporting within Europe of Exploration Results, Mineral Resources and Mineral Reserves.  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 2021 was initially approved at the PERC annual general meeting held on 7 May 2021 and was officially issued on 1 October 2021 following final review and editing.  The 2021 edition supersedes all previous editions and standards (including The Reporting Code, the IMM Reporting Code, the PERC Code, the PERC Standard 2013, the PERC Reporting Standard 2017, and the Recommended Rules for Public Reporting of Exploration Results, Surveys, Feasibility Studies and Estimates of Mineral Resources and Mineral Reserves in Sweden, Finland and Norway).

To allow existing users time to adapt to changes made in the PERC Reporting Standard 2021, PERC has agreed to allow for a transition period up to the end of 2022 during which time the PERC Reporting Standard 2017 may continue to be used. From 1 January 2023 usage of only the PERC Reporting Standard 2021 will be permitted.

Please note that the list of Recognised Professional Organisations (RPOs) is published as a separate document (updated October 2021).

The 2013 and 2008 versions of the Standard remain available for historical reasons only (for use in reading old company reports, for example).
