There are several classification systems for the economic evaluation of mineral deposits worldwide. The most commonly used schemes base on the International Reporting Template,^[1] developed by the CRIRSCO - Committee for Mineral Reserves International Reporting Standards, like the Australian Joint Ore Reserves Committee - JORC Code 2012,^[2] the Pan-European Reserves & Resources Reporting Committee' – PERC Reporting Standard from 2021,^[3] the Canadian Institute of Mining, Metallurgy and Petroleum - CIM classification^[4] and the South African Code for the Reporting of Mineral Resources and Mineral Reserves (SAMREC).^[5] A more detailed description of the historical development concerning reporting about mineral deposits can be found on the PERC web site.^[6] In 1997, the United Nations Framework Classification for Resources (UNFC) was development by the United Nations Economic Commission for Europe (UNECE). The Pan African Resource Reporting Code (PARC) is based on UNFC.
