Abstract
In order to compare Australia's national inventory of mineral resources with those of other countries and estimate total global stocks, it is useful to map different systems onto a common international classification template. The UNFC-2009 is an internationally applicable scheme for the classification and reporting of fossil energy and mineral resources. It can be applied directly but is also designed to align with other widely used mineral resource classification schemes such as the Template of the Committee for Mineral Reserves International Reporting Standards (CRIRSCO). Geoscience Australia maintains an inventory of Australia's mineral resources according to its National Mineral Resources classification scheme. The compilation of national resource stocks is derived from companies listed on the Australian Securities Exchange who are required to report publicly on ore reserves and mineral resources using the Joint Ore Reserves Committee (JORC) Code - the Australian version of the CRIRSCO Template. The highest category in the national system is 'Economic Demonstrated Resources' (EDR) which is considered to provide a reasonable estimate of what is likely to be available for mining in the long term. In summary: EDR comprises mainly current JORC Reserves and Resources where, (i) The JORC Reserves component of EDR correlates with UNFC's class of 'Commercial Projects', and (ii) The JORC Resources component correlates with UNFC's class of 'Potentially Commercial Projects'. Subeconomic Resources in the national system are largely from historic company reports, but include minor proportions of resources from latest company reports, and correlate with a subclass of the UNFC's 'Non-Commercial Projects'.
