need to protect the investing public, the past three decades have witnessed the publication of reporting codes for all the world’s main stock exchanges, as well as the release of an international reporting template for the public reporting of Exploration Results, Mineral Resources, and Mineral Reserves by the Combined Reserves International Reporting Standards Committee (CRIRSCO). Many of the codes now have commodity-specific reporting sections for coal. However, due to the fact that the governing codes have developed to such an extent, some have questioned the need for coal-specific standards. We would argue that coal resource estimation does require commodity-specific guidelines, as the processes of coal formation include aspects that are unique and which are fundamentally different from those that apply to most other mineral deposits. In addition, certain coal qualities may be of special interest for specific uses and technological applications, and may require very specific analytical work. Of the codes that have commodity-specific sections for coal, two are prescriptive (the USA and Canada) and two are descriptive (South Africa and Australia) and are considered as guidelines. Though termed ‘guidelines’, most institutions involved in the business of coal resource estimation, evaluation, and ultimately with the goal of raising funding, consider these guidelines as prescriptive, and as a set of standards that must be addressed for a Coal Resource to be considered as being reported in accordance with the required code. While most of the internationally recognized reporting codes have become very similar, including the South African Code for Reporting Mineral Resources and Mineral Reserves (the SAMREC Code, 2007 as amended 2009; 2016) and that of the Joint Ore Reserves Committee (JORC, 2012), their coalspecific guidelines have recently diverged and differ in a number of significant ways.
