Thiess EGM Australian Mining Michael Wright and Wesfarmers Resources Managing Director Stewart Butel

Under the four-year $570m contract extension, complements the current 10-year agreement signed in 2010, Thiess will continue its activities to optimize productivity in overburden removal and coal mining.

Wesfarmers Resources managing director Stewart Butel said that Thiess and Wesfarmers Resources worked jointly to review areas of efficiency and agree on a strategy to ensure Curragh maintains its position as a cost-competitive operation.

Thiess managing director Bruce Munro said, "We have worked closely with Wesfarmers Resources since 2004 at the Curragh North operation and this contract extension will deliver greater value in challenging times to benefit the mine and our stakeholders."

Leighton Holdings Chief Executive Officer Hamish Tyrwhitt said, "The Curragh North extension and Thiess’ $550 million Lake Vermont expansion announced last month are compelling testimony to the value proposition the Leighton Group has in the contract mining market."
