Pan-European Code for Reporting of Exploration Results, Mineral Resources and Reserves (PERC). The PERC Code for Reporting of Exploration Results, Mineral Resources and Mineral Reserves sets out minimum standards, recommendations and guidelines for Public Reporting of Exploration Results, Mineral Resources and Mineral Reserves in the United Kingdom, Ireland and Europe. The Code has been adopted by the Institute of Materials, Minerals and Mining (IoM3), the Geological Society of London (GSL), the European Federation of Geologists (EFG) and the Institute of Geologists of Ireland (IGI), and is therefore binding on their individual members.

The underlying Reserves Definitions were unchanged from those published by the SPE/WPC in 1997. Additionally, in 2001 the SPE/WPC/AAPG jointly published Guidelines for the Evaluation of Petroleum Reserves and Resources as clarifications for the application of the 2001 and 1997 documents. Further clarification was provided in the Glossary of 2005, in particular by the definition of the term commercial, and thereby reserves. Code list value Valid
