The "Guidelines for the Estimation & Reporting of Australian Black Coal Resources and Reserves" (the Guidelines) are referred to in the JORC Code, which now includes 'Coal' in its main body rather than as an appendix. The processes/procedures outlined in these guidelines are not considered compulsory, but their use is recommended.
