Moolarben Mine locationThe Moolarben Coal website is currently experiencing technical difficulties which is preventing access. Yancoal Australia is currently endeavouring to reinstate access as a matter of priority. We anticipate that the website will be operational by 15 July 2015. In the interim, if you have any questions regarding Moolarben operations, please make contact via the Community Hotline (1800 556 484) for further assistance.


The Moolarben Coal Mine is a world-class coal asset situated within the Western Coalfields of New South Wales, near the village of Ulan, approximately 45km northeast of Mudgee and 25km east of Gulgong.

The project covers an area of about 11,000ha (110 sq km) and adjoins the Ulan Mine (Xstrata/ Mitsubishi) to the northwest and the Wilpinjong Mine (Peabody) in the east. Operations comprise an existing open cut mine producing export quality thermal coal and an underground thermal coal development project.

Moolarben currently produces several export thermal coal products with differing ash content from the open cut mine, with recoverable reserves totalling 313Mt (Dec 2013). Moolarben benefits from the geology of the Ulan coal seam, which has an average thickness of approximately 12 metres throughout the deposit, a low strip ratio and a relatively simple mining operation.



A world-class, low cost coal asset



The low life-of-mine strip ratio of 3.3 and the modern 13.5Mtpa capacity Moolarben coal handling and preparation plant (CHPP) places the Moolarben open cut mine into the bottom half of the Australian coal mine cost curve. Yancoal Australia is currently assessing various options to increase the Moolarben CHPP capacity to coincide with the start up of mining in the underground (UG) areas. Coal produced from the UG1 and UG2 areas does not require washing. However, if the higher ash UG4 is mined in the future, its product will require washing.

Subject to obtaining all the approvals required for Stage 2 of Moolarben open cut production will increase to 13Mtpa ROM coal as open cut 4 is developed and longwall mining may commence in UG1 in 2018. Total production from the mine will be 17Mtpa ROM coal when the expansion is completed.

Moolarben has an established rail loop and loading facilities capable of loading trains within the required time cycle. The mine has existing port capacity through NCIG

The Moolarben Mine produces a number thermal coal products with varying ash content. These thermal coal products are priced with reference to the Newcastle coal benchmark price adjusted for the energy content of the products. The coal is sold to many Asian power customers with a number of South Korean utilities having life of mine offtake contracts. At full production, the Moolarben Coal Complex will have the capacity to produce 17 million tonnes per annum (MTPA) of ROM coal and employ approximately 450 personnel.

Up to 500 workers were employed during the initial construction phase of the project and over $60 million of the capital expenditure was spent in the immediate regional area from Scone to Mudgee and Dubbo.
