Isaac Downs

Project Details


Stanmore proposes to develop the Isaac Downs Project, an open cut metallurgical coal mine expected to produce up to approximately 35Mt of ROM coal over 16 years.

Isaac Downs is located in the Bowen Basin coal field, approximately 145km south-west of Mackay and 10km south-east of Moranbah.

Isaac Downs will support stable employment and economic opportunities in Moranbah and the region by extending the life of the company’s assets at the Isaac Plains Complex. The project will limit its footprint by using Stanmore’s existing coal processing plant and rail infrastructure which links the mine to Dalrymple Bay Coal Terminal.

The project will:

  • Employ approximately 250 people during construction and approximately 300 people during operations. In addition, there will be opportunities for local employment in construction, transport and the supply of goods and services.
  • Maintain a stable level of employment and economic activity in Moranbah and the region.
  • Contribute significantly to the State's economy through more than $200 million of forecast coal royalties to the Queensland Government.
  • Capitalise on existing infrastructure at Isaac Plains Complex, limiting the project's environmental footprint.
  • Continue Stanmore Coal's commitment to progressive rehabilitation and environmental stewardship within the mine's operating footprint.

Approvals timeframe

Stanmore IP South Pty Ltd (a subsidiary of Stanmore Coal) has prepared an environmental impact statement (EIS) for the project under the Environmental Protection Act 1994 (EP Act).  Stanmore is currently assessing its response to public submissions.  Stanmore IP South Pty Ltd has lodged mining lease applications and an environmental authority application to enable development of Isaac Downs.

Isaac Downs has been declared a Controlled Action by the Commonwealth Department of Environment and Energy, which means the project will be assessed and approved under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).

Subject to all required approvals, construction and mining operations are expected to commence in 2021.
