Mount Thorley Warkworth

Mount Thorley Warkworth (MTW) is an integrated operation of two open cut mines located adjacent to each other 15 km south west of Singleton in the Hunter Valley region of New South Wales. The operation supplies international and domestic markets with up to 10 million tonnes of semi-soft coking coal and thermal coal per annum.

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, and in 2001 Coal & Allied purchased an interest in the mine. In January 2004, the two mines were integrated to improve efficiency and operate as one business.

Coal & Allied is currently investigating options to extend mining within its existing Warkworth lease, which would add a further 21 years of operation to the mine.  Read more about the Warkworth Extension project.
