Appendix 5A Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (The JORC Code) Introduced 1/7/96. Origin: Appendix 17.

This was followed in 1998 by an agreement to incorporate the CMMI definitions into the International Framework Classification for Reserves and Resources – Solid Fuels and Mineral Commodities, developed by the United Nations Economic Commission for Europe (‘UN-ECE’). As a result of the CRIRSCO/CMMI initia
