The prestigious contract comes as Anglo announced that its Moranbah North and Capcoal mines had increased their longwall cutting hours by 63% and 33%, respectively.

The term of the contract is three years, with options to extend annually for an additional two.

Work under this contract is estimated to build over the next 12 months and contribute $150 million over the term of the contract, including the options period, Mastermyne said.

The scope of work, which covers the Anglo American underground sites in the Moranbah region, encompasses design, supply and installation, recovery and maintenance of ventilation structures and devices, installation of secondary support; outby support and maintenance activities, and conveyor belt installations and recovery.

The contract replaces the existing umbrella contract at Moranbah North mine, which expired on April 6.

Anglo American opted not to trigger the one-year option, but instead replace the contract with this new contract for a further 3+1+1 years.

Mastermyne CEO Tony Caruso said: “We are very pleased with this result and look forward to continuing our strong working relationship with Anglo American.

“The awarding of this major tender reinforces Mastermyne’s strong standing in the coal sector and we are looking forward to building on this success with further contract wins.”

Anglo is seeking to create a centre of underground coal mining excellence and innovation around Moranbah, with construction of its greenfield Grosvenor metallurgical coal project in Queensland nearing 50% completion.

Critical engineering and procurement activities have been completed and the majority of the project budget has been contracted and committed.

Longwall production remains scheduled to start at the end of 2016 and within budget of $1.95 billion.
