Mount Thorley Warkworth

Mount Thorley Warkworth (MTW) is an integrated operation of two open cut mines located adjacent to each other, 15 kilometres south-west of Singleton in the Hunter Valley region of New South Wales.

The operation supplied international and domestic markets with 11.7 million tonnes of semi-soft coking coal and thermal coal in 2015.

Mount Thorley has been in operation since 1981, and after a business restructuring of mining company R.W. Miller, Coal & Allied became managers of the mine in 1989. Warkworth Mining began operations in the same year as Mount Thorley (1981).

Yancoal Australia acquired Mount Thorley Warkworth on 1 September 2017.

Community

Mount Thorley Warkworth seeks to be more than just a major source of local employment and economic growth, rather to work in partnership with the local community.

Community Consultative Committee

The Mount Thorley Warkworth Community Consultative Committee meets regularly to provide a forum for open discussion between the community, Council and Yancoal representatives. The committee discusses issues directly relating to the mining operation and environmental performance, keeping the community informed on these matters and potential impacts.

Community partnerships

The Coal & Allied Community Development Fund (previously called the Coal & Allied Community Trust) was established in 1999 to support communities in the Hunter Valley to build community capacity, address development challenges and take advantage of emerging opportunities.

Since its inception in 1999, the Coal and Allied Community Development Fund has contributed more than A$14 million to projects aimed at providing benefits for the local community. The Coal & Allied Community Development Fund is continuing its long running contributions to building capacity in the Hunter Valley, with the announcement in late 2014 of a A$3 million commitment for disbursement between January 2015 and December 2017.
