About Mt Arthur Coal
Mt Arthur Coal is operated by Hunter Valley Energy Coal Pty Ltd, a wholly owned subsidiary of BHP. Mt Arthur Coal is an open-cut energy coal mine in the Hunter Valley region of New South Wales (NSW), situated approximately five kilometres south of the township of Muswellbrook.
About the continuation project
Work has commenced on an application to enable the continued operation of Mt Arthur Coal beyond 30 June 2026, which is when the planning approval expires.
New State Significant Development (SSD) and Commonwealth Environment Protection and Biodiversity Conservation Act approvals as well as a new mining lease are required for operations to continue beyond 30 June 2026.
Mt Arthur Coal has now commenced a comprehensive stakeholder engagement program to ensure there is opportunity for community members and other key stakeholders to have early input into the project.
Key elements of the Mt Arthur Coal planning approval include:
- Approval to continue operating through to 30 June 2045 – a total of 19 additional years
- Continued employment of up to 2,600 people
- Extension of open-cut operations and additional overburden emplacement
- Minor extensions to the existing Mining Infrastructure Area (MIA) including upgrades to workshops, stockpiles, electricity distribution and other ancillary infrastructure (see map in Project footprint)
- Construction and operation of a new Western MIA for ancillary infrastructure including facilities for workforce and administration (see map in Project footprint)
- Ongoing progressive rehabilitation of landforms, consistent with the geofluvial design
This planning approval will extend the mine further to the west of the township and will not require changes to existing approved hours of operation or coal transportation including rail movements.
Benefits of continued operation
The Mt Arthur Coal planning approval process marks the next step in the life of a significant open-cut coal operation that has played a crucial role in the Hunter Valley since the 1960s. The benefits of continued operation include:
- Ongoing employment opportunities for a workforce who predominantly live and work in the region, as well as new jobs associated with project-related construction activities
- Ongoing delivery of shared value for communities in the Hunter Valley and associated local investment
- Generation of additional royalties to NSW
Progress so far
To enable the continuation of Mt Arthur Coal’s operation beyond mid-2026, a State Significant Development proposal submission is required.
As part of this proposal, we are preparing an Environmental Impact Statement (EIS) which includes assessments of the continuation project’s potential social, economic and environmental impacts.
