Thiess managing director Michael Wright said: “The Melak contract extension is a testament to our performance at the mine since 2008. We are pleased to extend our partnership with the Bayan Group and continue our focus on delivering innovative and sustainable mining solutions for our client.”

The contract, with revenue of $180 million, continues Thiess’ mining development and operations at the site through to December 2019, parent company CIMIC CEO Marcelino Fernandez Verdes said.

“Thiess’ global platform enables it to deliver safe, efficient and productive outcomes for clients across a variety of geographical locations,” he said.

The contract extension follows Thiess being awarded a contract in January with revenue of approximately $115 million to continue operating the southern pits of the Dawson Coal Mine in Central Queensland, from 1 January 2016.

Under that contract, Thiess will provide mining services including the removal of overburden and coal mining.

The new agreement with mine owner Anglo American builds on a long standing involvement at the mine, Verdes said.

“The contract recognises Thiess’ ability to continue to deliver sustainable mining solutions and meet client commitments,” he said.
