The past three decades have witnessed the publishing of reporting codes for all the main stock exchanges, as well as the evolution of a uniform international standard covering the definition, estimation, and public reporting of Mineral Resources. Many of these reporting codes have commodity-specific reporting sections for coal, but only two countries (Australia and South Africa) have specific guidelines for reporting on coal resources. Both of these companion documents (SANS 10320:2016 and the Australian Guidelines for the Estimation and Classification of Coal Resources, 2014) have recently been updated. Unlike their parent codes, which have become increasingly similar, these new guidelines have diverged and are different in a number of significant ways, which in turn will have an impact on coal resource estimators working in the coalfields of south-central Africa, particularly in countries where no commodity-specific guidelines for coal exist. |
