Holders of coal authorities are required under the Mining Act 1992 to lodge reports on operations that include expenditure, along with all maps, plans and data that are necessary to satisfactorily interpret the reports.

Reports include:

  • Annual reports
  • Partial relinquishment reports
  • Final reports
  • Geophysical reports

Geoscientific reports and data must be submitted in digital form in accordance with Exploration reporting: a guide for reporting on exploration and prospecting in NSW.

For more information on reporting requirements see the Mining Regulation 2016.

Guidelines and reporting templates


Geoscientific reports and data submitted to the department under coal authorities are treated as confidential for a period of 5 years after lodgement, or until the authority is cancelled or relinquished.

Compulsory online reporting

EROL is an online report preparation and lodgement facility for title holders, operators or agents. Users need to register for an account online at the EROL login page.

Data files attached to a report are reviewed for compliance to data templates as the first step in assessing a report. This quality assurance process ensures the data can be electronically uploaded into MinView.

Extensions and exemptions from reporting

The Mining Regulation 2016 allows for authority holders to apply for an extension of the period within which a report must be lodged, or for an exemption from reporting requirements. However, extensions and exemptions are not generally granted except in cases of extreme hardship.

Applications for extensions or exemptions must be lodged not later than 30 days before the date the report is due using the ER01 - Extension or exemption from reporting form.

Exemption from reporting requirements does not exempt the authority holder from their obligation to fulfil other conditions of authority, especially the requirements to effectively explore, assess or mine the authority area.

Estimating and reporting Australian black coal resources and reserves

The Australian Stock Exchange (ASX) requires that all public reporting of resources and reserves of black coal complies with the Joint Ore Reserves Committee (JORC) Code, 2012 Edition.

When available, the department requires that Coal Resources and Coal Reserves included in reports required under the Mining Act 1992, associated regulations and conditions of title to comply with the JORC Code (2012 Edition).

Where reporting under the JORC code (2012 Edition) is not available, the department requires that all estimates of Inventory Coal, Coal Resources and Coal Reserves for black coal included in reports required under the Mining Act, associated regulations and conditions of title, are estimated in accordance with the Australian Guidelines for the Estimation and Classification of Coal Resources or its successor document as published from time to time by the Coalfield Geology Council of New South Wales and the Queensland Resources Council.
