About the Asset

The Maxwell Underground Mine is located east of Denman and south of Muswellbrook.

The mine will produce high quality coals with at least 75% capable of being used in the making of steel with the balance suitable for use in new-generation High Efficiency, Low Emissions (HELE) power generators.

The mine, approved by the NSW Government in December 2020, followed comprehensive environmental and technical analysis and more than eight years of ongoing consultation with the local community and our neighbours, ensuring the mine can comfortably co-exist with other industries and land use in the area.

Throughout the planning process we have taken a number of practical steps to reduce our impact on the environment and the community. To that end, we will be using the established facilities at ‘Maxwell Infrastructure’ to process and rail all coal we intend to mine at the Maxwell Underground Mine.

The construction phase will involve the generation of roughly 250 new jobs and the services of many local businesses and suppliers.  Once construction is complete the project will generate 350 full-time, long-term new jobs, delivering $55 million in wages into the local economy each year, and generate $1 billion to 1.2 billion of royalties for the NSW State Government over the initial 26 years of the Project.

During the construction phase and once mining begins, the mine will support local businesses and suppliers. Wherever possible, we will prioritise employing locals because we know how important it is for the benefits of this enterprise to stay in the local community.
