MONADELPHOUS CONTRACTS UPDATE

Leading engineering group Monadelphous Group Limited (ASX: MND) (“Monadelphous” or “the company”) today announced it has secured major maintenance and construction contracts with a combined value of approximately $350 million.

The contracts are with key customers in the Queensland coal industry and the West Australian oil and gas and alumina industries.

The new work secured in Queensland comprises:

• A three-year contract, valued at approximately $100 million, with BHP Billiton Mitsubishi Alliance (BMA) for dragline and shovel shutdown work across its Bowen Basin coal operations;

• Two contracts, totalling approximately $100 million, for civil, structural, mechanical and electrical work to supply and install an overland conveyor and a drift conveyor as part of the extension project at the Rio Tinto Coal Australia-managed Kestrel Mine near Emerald; and

• Two contracts with BMA’s Project Delivery Group for ongoing construction work on various sites in the northern region of the Bowen Basin over two years.

The new work secured in Western Australia comprises:

• A new contract with Woodside to provide mechanical commissioning support for its Pluto LNG Plant on the Burrup Peninsula. This contract is expected to be completed in the first half of 2012 and follows an initial major structural, mechanical and piping contract for the Pluto LNG Project which commenced in 2009 and is in the final stages of completion; and

• A new three-year contract to provide minor capital project services for BHP Billiton Worsley Alumina’s Refinery Project at Collie. The contract formally extends a continuous services relationship with Worsley Alumina which commenced in 2004.

“These contracts further reflect the importance we place on developing long-term relationships with quality customers. They demonstrate our continuing involvement in major projects and our commitment to support growth in the Queensland coal industry,” Monadelphous Managing Director Rob Velletri said.
