Under the contract, the engineering company will be responsible for the construction and placenment of an 18 kilometre long distance tailings and return pipeline located between the pit storage facility and mine coal handling processing plant.

The pipeline is expected to be completed by late 2016 and the contract pricing is not expected to be more than $33m.

Ausenco CEO Zimi Meka said: "We look forward to finalising the contract and working with BMA on a innovative pipeline solution that will facilitate ongoing operations at this mine.

"This award increases Ausenco’s work on hand (including preferred contractors) to over $300 million. Combined with other recent EPC and EPCM awards over the last few weeks improves Ausenco’s forward revenue visibility."
