Australian guidelines for the estimation and classification of coal resources / Австралийское руководство по оценке и классификации ресурсов каменного угля

1.2 Prior to September 1999 the estimation and reporting of Coal Resources and Coal Reserves in Australia were prescribed by the "Australian Code for Reporting Identified Coal Resources and Reserves (February 1986)". This code was ratified by the Government Geologists’ Conference in April 1986 and appended to the "Australasian Code for Reporting of Identified Mineral Resources and Ore Reserves" (The JORC Code), prepared by the Joint Ore Reserve Committee (JORC) in February 1989. The JORC Code was subsequently revised in 1992 and 1996. In 1999, a significant revision occurred which resulted in the inclusion of the reporting of Coal Resources and Coal Reserves into the “Australasian Code for Reporting of Mineral Resources and Ore Reserves”. This 1999 edition of the JORC Code referenced the 1999 edition of the “Guidelines for the Estimation and Reporting of Australian Black Coal Resources and Reserves”. The guidelines were updated in 2003 as the “Australian Guidelines for Estimating and Reporting of Inventory Coal, Coal Resources and Coal Reserves” (the 2003 Guidelines), and were referenced in the 2004 and 2012 editions of the JORC Code. 
1.2 “The JORC Code 2012 Edition”, herein referred to as “the Code”, provides minimum standards for public reporting of Exploration Results, Mineral Resources and Ore Reserves. The Code states in guidance notes for Clause 42 that for guidance on the estimation of Coal Resources and Reserves and on statutory reporting not primarily intended for providing information to the investing public, readers are referred to the “Australian Guidelines for Estimating and Reporting of Inventory Coal, Coal Resources and Coal Reserves” or its successor document as published from time to time by the Coalfield Geology Council of New South Wales and the Queensland Resources Council.

1.3 This successor document, the “Australian Guidelines for the Estimation and Classification of Coal Resources”, herein referred to as “the Coal Guidelines”, represents a substantial update of that work. It will continue to be reviewed periodically and re-issued as required. 
1.4 This document is not part of the Code, however adherence to the processes and procedures outlined in the Coal Guidelines is recommended by the Code. This document must be read in conjunction with the Code, and if any conflict is perceived between this document and the Code, the Code takes precedence. Guidance notes to Clause 42 of the Code states these guidelines do not override the provisions and intentions of the JORC Code. Competent Persons should as always exercise their judgement in the application of these guidelines to ensure they are relevant to the circumstances being reported. They may not be applicable for use in all situations in Australia or overseas. 
1.5 Some of the wording in the Coal Guidelines has been copied from the Code and the reader should note that requirements of the Code are mandatory if reporting of an estimate is said to meet the standard of the Code. 
1.6 References to Coal Reserves in the previous version of this document were a partial replication of Ore Reserves documented in the Code. Since Coal Reserves are adequately covered by the Code they are now not replicated in the Coal Guidelines. <...>
