PERC Standard

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

History

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).

    PERC List of RPOs

    The PERC list of Recognised Professional Organisations (RPOs) provides a list of the professional organisations and required membership levels that are accepted by PERC for the purpose of the definition of a Competent Person at Clause 3.2 of the PERC Reporting Standard 2021.

    To be accepted as a RPO by PERC, an organisation must satisfy the following criteria:

    • be a self-regulatory organisation covering professionals in the mining and/or exploration industry;
    • admit members primarily on the basis of their academic qualifications and professional experience;
    • require compliance with the professional standards of competence and ethics established by the organisation anywhere in the World (not just within the home jurisdiction of the organisation); and
    • have disciplinary powers, including the power to suspend or expel a member for breaches of professional standards of competence or ethics anywhere in the World.

     

    The minimum membership classes required by PERC are consistent with those in other CRIRSCO Reporting Codes and Reporting Standards and have been set at a level where the membership class is based on a system of peer scrutiny, including submission of documentation demonstrating experience and expertise and normally a professional interview, or where there is no interview PERC would need to be satisfied that the system of peer scrutiny is sufficiently robust.

      Previous versions

      The PERC Reporting Standard 2017 was published after approval at the PERC annual general meeting held in May 2017. The PERC Reporting Standard 2017 can continue to be used until December 2022 after which time use of the PERC Reporting Standard 2021 becomes mandatory.

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