Overview

Upon closure of mining activities by Rio Tinto, Liberty Industrial has been engaged to remove all infrastructure located within the mining lease, including the process plant and ancillary facilities such as the mine camps, power station and airport. The scope of works also include the construction and management of site- based landfills and the remediation of contaminated areas across site.

Challenges

Site remoteness (the closest township is at least 185km away)
Hot, humid and rainy weather.
The induced collapse of high rise structures and difficulty reaching the ROM structures and connecting conveyors located on an escarpment.

Robust Solutions/Exceptional Outcomes

Robust solutions

To overcome some of the key challenges, we have established a self-sufficient site and minimised the requirement for frequent transport, undertook staged project activities and implemented a comprehensive environmental management plan, mobilised a fleet of high-reach excavators ranging from 100 to 200t, developed detailed methodologies and 3D modelling for the induced collapse of overland conveyor leading to the ROM pad. Our project manager also worked closely with Traditional Owners and ensured work opportunities were presented fairly.

Exceptional outcomes

To complete this project without injury and within the closure timeframes and allocated budget, we are relying on our skilled and competent project team, state-of-the-art plant and equipment, as well as efficient stakeholder communication and management that is supported by the strength of our existing relationship with Rio Tinto.
