Independent Monitor Report on McArthur River Mine

Media statement
Darwin, Australia
3 May 2022


The Independent Monitor (IM) Report on McArthur River Mine for the period 1 May 2020 to 30 April 2021 has found continuous improvement in environmental management and performance at the mine.

The primary objective of the IM’s Annual Environmental Performance Audit Report (AEPAR) is to provide transparency to the local communities in the Gulf Region on whether McArthur River Mining Pty Ltd (MRM) is fulfilling and managing compliance related to environmental obligations.

The AEPAR assesses MRM’s performance in a wide range of areas, including its compliance with regulatory approval conditions; its implementation of NT Environment Protection Authority (EPA) recommendations; its implementation of environmental commitments; and its environmental risk management process.

MRM achieved a high level of overall compliance with the conditions imposed under its Authorisation and Waste Discharge Licence, as well as with the implementation of the NT EPA recommendations. The IM found that MRM has continued to avoid or minimise potential environmental risks through proactive management and monitoring across a wide range of site activities.

The Independent Monitor found the mine demonstrated a high level of environmental performance with no significant environmental issues requiring urgent investigation during the audit period.

The AEPAR also found that the McArthur River and its tributaries were considered to be in good health and that it is safe for people to eat fish from the McArthur River including barramundi, sooty grunter and cherabin (freshwater prawns).

Adam Hatfield, Acting General Manager of MRM, said: “The Independent Monitor continues to conduct a detailed review of our environmental performance and make constructive recommendations for how we can continue to improve.”

“The entire workforce at MRM is committed to operating responsibly and I’m very proud of their achievements. The Independent Monitor’s positive findings about our environmental performance and the continued good health of the McArthur River are a testament to the ongoing progress we’ve made in recent years.”

The report assessed a total of 1,055 conditions. There were no non-compliances. There were 39 requirements scored as partly compliant, however, these were largely administrative (e.g. documentation procedures) and posed a low risk to the environment.
