Macmahon Holdings Ltd has announced the execution of a new three-year contract at the Byerwen coking coal mine in Queensland’s Bowen Basin. This follows Macmahon’s Notice of Award for the project announced to the ASX on 10 April 2025.
Macmahon has been providing open cut mining services, including load and haul, and crusher feed, at Byerwen since the establishment of the mine in 2017 and provides employment to 545 people on site. The mine is owned by Byerwen Coal Pty Ltd, a joint venture between QCoal Group and Japanese steel manufacturer, JFE Steel.
This new contract is a continuation of services from December 2025 and is valued at A$792 million over its three-year term, with an option to extend a further two years which would increase the value of the contract to A$1.32 billion.
As Macmahon already has its people and mining fleet deployed and operating at Byerwen, no new capital expenditure is required beyond sustaining capital budgets. Macmahon’s FY26 guidance remains unchanged.
Managing Director and CEO Michael Finnegan said: “We are very pleased to finalise the contract at Byerwen, where we have worked providing mining services since the mine commenced operations in 2017. The QCoal relationship and Byerwen project are incredibly important to Macmahon and have helped underpin the company’s continued growth over the last nine years.”
