During the course of the year, Macmahon strengthened its order book with key contract wins, including at the Byerwen coal mine in Queensland and the Mount Monger gold mine in Western Australia.
Macmahon has been working at the Byerwen coal mine in the Bowen Basin since its greenfield days in August 2017 and undertakes all drilling, blast design, loading, hauling, haul road maintenance and mobile plant maintenance work.
In June, Macmahon’s contract at Byerwen was extended until at least November 2023, with the option of another two-year extension by joint venture owners QCoal Group and JFE Steel.
Under the contract extension, Macmahon will boost production at the hard coking coal project from five to 10 million tonnes of coal per annum.
During the 2020 financial year, Macmahon not only enhanced operations for its mining customers but also its won portfolio, finalising the acquisition of the GBF Underground Mining business.
Through GBF Underground Mining, Macmahon is executing works at the Mount Monger gold mine, after inking the contract with Silver Lake Resources.
This boosted Macmahon’s order book in the midst of the COVID-19 pandemic, positioning it strongly to work through this challenging period.
Macmahon’s work at Mount Monger is representative of its versatility across a range of commodities, servicing multiple gold mines, in addition to its work at Queensland coal sites.
The contractor also provides a full scope of services for fellow Western Australian gold operation, Newcrest Mining’s Telfer gold-copper mine in the Great Sandy Desert.
At Telfer, Macmahon has been contracted since 2016 on a rolling basis, which will last until 2022. It mines the open pit at the fly-in fly-out (FIFO) mine, completes bulk earthworks, drill and blast work, hires out equipment and subcontractors and is responsible for dealing with mining waste materials.
