The SANS coal standard (SANS 10320: South African Guide to the Systematic Evaluation of Coal Resources and Coal Reserves) is currently under revision. SANS is a standard under the South African Bureau of Standards (SABS), which addresses public reporting of Coal Resources and Coal Reserves. As such, it contains various valuable aspects that are relevant to the declaration of Coal Resources and Coal Reserves. The SAMREC Code, therefore, insists on the SANS 10320 being consulted when making a coal declaration or for Public Reporting. This has allowed the Coal section of the Code to be revised and abbreviated.
It must be noted that some aspects of coal reporting were not fully consistent with the SAMREC Code. For example, the requirement of a Feasibility Study to be completed in order to declare a Proved Coal Reserve. The classification of Proved and Probable Coal Reserves has been modified to reflect a minimum requirement of a Prefeasibility Study or Life of Plan which now aligns this definition with international requirements. According to SAMREC, 2016, only Coal Resources on a Mineable Tonnes in Situ basis (previously reported as Gross Tonnes in Situ) can be reported, while Coal Reserves may only be reported on a ROM or Saleable basis.
