Macmahon Holdings, an Australian Securities Exchange (ASX)-listed mining infrastructure services provider, has secured a three-year extension for its mining services at the Byerwen coking coal mine in the Bowen Basin in Queensland, Australia.
The contract extension is expected to contribute approximately A$900m ($543.5m) to Macmahon’s order book.

With the company’s workforce and mining fleet already at Byerwen, no additional capital expenditure is required, aside from the allocated sustaining capital budgets.
The contract extension, which continues services from October 2025, is pending the finalisation of certain terms agreed upon in principle. The terms are expected to be concluded by 30 September 2025.
The Byerwen mine is owned by Byerwen Coal, a joint venture between QCoal Group and JFE Steel, a Japanese steel manufacturer.
Since the establishment of the Byerwen mine in 2017, Macmahon has been delivering open-cut mining services, which include loading and hauling, as well as crusher feed operations. The company employs more than 800 individuals on site.
Macmahon CEO and managing director Michael Finnegan said: “We are very pleased to continue as the mining contractor at Byerwen where we have worked closely with the team since the mine commenced operations in 2017. We will continue to refine the terms and conditions over the next few months with a focus on mutually beneficial outcomes that will enhance operational efficiencies on site.
“The QCoal relationship and Byerwen project have been key to the Macmahon business stabilising over the last eight years. The teams are grateful and excited that they will have the opportunity to continue to develop that relationship on site and corporately. I would like to thank the Byerwen Coal and Macmahon teams for their continued dedication and support and look forward to finalising the contract.”
In March 2025, Macmahon Holdings was appointed by PT Citra Palu Minerals to provide underground mining services for the Poboya gold project in Sulawesi, Indonesia.
