Mount Arthur coal mine is an open-pit coal mining operation located near Muswellbrook, Australia, managed by BHP since 2002. It stands as the largest coal extraction site in New South Wales, boasting an annual production capacity of 20 million tons, mining 21 distinct coal seams, and employing approximately 2,000 personnel. Up until 2020, the mine served both local and overseas markets but has since transitioned to focus solely on export activities.
The coal is moved by Aurizon along the Main Northern railway line to the Port of Newcastle for international shipment. In earlier years, a 10-kilometre conveyor belt system transported coal directly to Bayswater and Liddell Power Station.
In August 2020, BHP revealed intentions to divest from the mine. Nevertheless, by 2021, the asset's worth declined sharply to a negative $200 million due to environmental rehabilitation costs, a significant drop from its previous valuation near $2 billion. After failing to find a purchaser, BHP opted in June 2022 to maintain ownership, extend operational licenses through 2030, and prepare for eventual closure. Following shutdown, BHP is investigating redevelopment possibilities such as establishing a pumped-storage hydroelectric facility at the location.
