Macmahon Holdings has received a notice of award for a three-year contract extension at the Byerwen mine, expected to earn the company about $900 million.
Macmahon has been providing open-cut mining services, including load and haul, and crusher
feed, at Byerwen since the establishment of the coking coal mine in the Bowen Basin in 2017.
It employs 800 people at the operation, owned by a joint venture of QCoal Group and Japanese steel manufacturer JFE Steel.
Macmahon said the contract extension covered a continuation of services from October 2025.
It remains subject to final documentation in-principle agreed terms which are intended to be finalised before September 30.
“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,” managing director and chief executive officer Michael Finnegan said.
“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.”
