Three customers. Three scopes. One combined figure. Monadelphous Group Limited (ASX:MND) told the market on 28 October 2026 that it has been awarded new resources-sector contracts valued at approximately $150 million in total. The company named Rio Tinto, BHP and Whitehaven Coal as its customers and set out the work for each, but it did not split the value by contract.

Rio Tinto marine infrastructure maintenance

The Rio Tinto contract runs for four years. Monadelphous will continue to provide maintenance services and minor projects on marine infrastructure at the Dampier and Cape Lambert ports in Western Australia. The announcement describes the work as a continuation. It gives no individual contract value and no start date.

BHP Ministers North

BHP has awarded the second contract for the Ministers North Project in the Pilbara region of Western Australia. The scope covers the establishment and maintenance of temporary non-process infrastructure facilities, along with associated services. Monadelphous said the work is expected to be completed by mid-2028. No separate value was disclosed.

Whitehaven Coal shutdown services

The third contract is with Whitehaven Coal. It carries a term of three years, with an option to extend for a further two, and covers shutdown services across Whitehaven's mine sites in Queensland and New South Wales. The two-year extension is an option, so the three-year term is the only period the announcement presents as firm. Shutdown services generally refer to planned maintenance carried out while plant is taken out of operation, although the announcement does not elaborate on how the work will be scheduled.

What the announcement covers

The announcement is brief and runs to a single page of text. It names the customers and scopes without further commercial detail.

Together, the contracts span iron ore port infrastructure maintenance, a Pilbara project support scope and coal mine shutdown work, across customers in Western Australia, Queensland and New South Wales.

The company did not say how much of the approximately $150 million will be recognised as revenue in any particular financial year, and it did not say whether the figure includes the Whitehaven extension option. No earnings guidance, margin information, workforce numbers or contract conditions were provided. The total is the company's own estimate of contract value at the time of announcement.
