Mining and production

Hunter Valley Operations (HVO) is a multi-pit open cut mine, using a dragline truck and shovel method. The operation's employees work in shifts to keep the mine operational 24 hours a day, seven days a week.

Operations are centred in the Wittingham Coal Measures of the Hunter Coalfield, which is part of a Permian coal basin known as the Sydney basin.

In 2020 the mine produced 17 million tonnes of thermal coal and semi-soft coking coal. After being washed and prepared for sale, the coal is loaded onto trains for transportation 90 kilometres to the Port Waratah Coal Terminal in Newcastle where it is shipped to international customers.

Production commenced at HVO in 1949 at the current West Pit, which was then part of the Howick mine. The Hunter Valley No. 1 mine began production in 1979. In 2000 Coal & Allied merged the Howick and Hunter Valley mines to create HVO. The Lemington mine, which began production in 1971, was acquired and merged into HVO in 2001.

In March 2009 Coal & Allied received approval from the NSW Government to replace the multiple approvals under which HVO South operated with a single Project Approval valid for 21 years to 2030. The approval included extraction of a further 84 million tonnes of coal and upgrades to a range of infrastructure at the mine.

Yancoal Australia acquired HVO on 1 September 2017.
