April 2017 - ongoing

Thiess first began mining at Mount Pleasant as scheduled on 20 November 2017, following a successful five-month mobilisation period.


Located 2.5km from Muswellbrook in the Upper Hunter Valley, New South Wales, the Mount Pleasant Operation is a greenfield open cut coal mine with an estimated 474 million tonnes of reserves to be mined.

Before mining operations began, Thiess developed site systems and processes, mobilised and assembled plant from across four states, and recruited and trained personnel. The team also safely prepared the explosives facilities and stripped topsoil from mining areas. In the first year of the contract achieved a TRIFR of 0.

The workforce has been built up with a focus on developing a strong performance culture. This culture values everyone’s contribution equally and is based on providing local opportunities.

More than 80% of Mount Pleasant Operation’s workforce lives locally. The mine has attracted a diverse workforce with female and Aboriginal and Torres Strait Islander participation. Mount Pleasant also engages a local Indigenous organisation to provide labour, machinery and cleaning services.

Today, Thiess is responsible for providing a full mining service and increasing mining production to 10.5 million ROM tonnes per annum. The team is also undertaking progressive rehabilitation. Works commenced less than six months after overburden removal began, and prior to coal mining.
