History
Macmahon Holdings was founded in 1963 by Brian Macmahon. Its first mining contract was for excavation works at the Nobles Nob Gold Mine at Tennant Creek in the Northern Territory. In 1983 it was listed on the Australian Securities Exchange. In 1987 it acquired FK Kanny & Sons, an open cut mining contractor in Western Australia. In 1994 it commenced operations in Chile and Malaysia.[1] In 1994 it purchased Kalgoorlie based underground mining specialist National Mine Management.[2]
In 2005, it purchased the Northern Territory operations of Henry Walker Eltin.[3] In 2006, a 60% shareholding in rail contractor MVM Rail was purchased, with COMSA owning the other 40%.[4][5][6]
In January 2013, Macmahon secured its largest ever contract from Fortescue after it was awarded a $1.8 billion contract for the Christmas Creek mine's expansion. The five-year contract would deliver all aspects of mine operations, including drill and blast, overburden removal, ore harvesting, maintenance of equipment and associated services, for the expansion.[7]
In December 2012, the construction business was sold to Leighton Holdings.[8] In August 2024, it re-entered the construction sector, acquiring Decmil.[9][10]
