Areas of Action

How we’re protecting the environment


Increasing our market share in rehabilitation work is a key part of our business strategy. This work typically includes completing earthworks and revegetation on land disturbed by mining activities to ensure it is stable, safe and suitable for post-closure use. During 2020, we rehabilitated a total of 107 hectares for our clients.

Waste and recycling

Macmahon remains committed to ensuring that all waste materials are disposed of in an approved and environmentally responsible manner, including materials such as tyres, oils and lubricants and office waste. We often repair tyres to extend life but once they have reached a worn out state, they are disposed of through Environmental Protection Authority approved channels and the use of certified waste disposal companies.

Water management

Macmahon is committed to reducing the impacts on water quality associated with its mining operations. Regular sampling and reporting takes place at the Sejorong River in Sumbawa, near Batu Hijau’s copper-gold mine in Indonesia.

Environmental Policy

Our Environmental Policy objective is to minimise the adverse impact on the environment as a result of our business activities.
Environmental Policy
There are over 200 snake species in Australia, and over half of these are venomous. That’s why Macmahon regularly runs a snake handling course for our staff to learn how to navigate an encounter. We’re passionate about biodiversity and snakes are a part of our wildlife. A world without snakes would cause many other problems like an increase in rat and mice populations.
