Mount Thorley Warkworth mine

The Mount Thorley Warkworth mine is an integrated mine comprising two open cut pits located approximately 15 km south west of Singleton in the Hunter Valley in New South Wales. The mine "supplies international and domestic markets with up to 10 million tonnes of semi-soft coking coal and thermal coal per annum."

On its website Coal & Allied states that "Mount Thorley has been in operation since 1981, and after a business restructuring of mining company 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." (See Warkworth Extension for more details).

As of the end of 2008 Coal & Allied stated the project had 710 employees. On its website Coal & Allied states that "in 2008 Mount Thorley produced almost two million tonnes of thermal coal and almost one million tonnes of semi-soft coking coal. Warkworth produced more than five million tonnes of thermal coal and more than 400,000 tonnes of semi-soft coking coal. After being washed and prepared for sale, the coal is loaded onto trains for transportation 90km to the Port Waratah Coal Terminal in Newcastle where it is shipped to international customers. Mount Thorley had marketable reserves of 24 million tonnes as at 31 December 2008. Warkworth had marketable reserves of 278 million tonnes as at 31 December 2008."
