MACA has won a contract for Karara Mining's Hinge DSO iron ore project in Western Australia as it appoints a new CEO.
The contract, worth approximately $90 million, will run for around 17 months.
MACA has already begun initial civil and infrastructure works, with major works expected to commence later this month.
The major works consists of open pit mining, drilling and blasting, loading and hauling, and crushing and screening.
Speaking on the win MACA operations director Geoff Baker said "it is pleasing to have once again secured a new contract against the backdrop of a lower price environment for iron ore and a competitive market place".
Karara is a joint venture between Gindalbie Metals and China's AnSteel Group.
The win comes on the back of Chris Tuckwell's appointment as managing director and CEO, who will step back in to the role of CEO on August 4.
Current CFO Ross Williams will also move from his role, stepping in to the role of non-executive director as Joe Sweet resigns from the position.
Williams CFO position will be backfilled by company secretary Peter Gilford.
