McArthur River Mine (MRM), located in the Gulf of Carpentaria in the Northern Territory, is a world-class zinc-lead mine containing the second largest zinc deposit in the world. MRM is focused on operating in a safe and responsible manner. The mine is an important part of the Northern Territory’s resources sector and makes a significant contribution to the economy. 

MRM has faced some environmental challenges, including the management and storage of waste rock. We continue to address these challenges openly and have made good progress, including:

  • Eliminating emissions from our waste rock area
  • Further improving the stability of our tailings storage facility
  • Conducting a thorough fish testing programme, which determined that although a small number had elevated levels of lead, they are restricted to a creek on our site that is inaccessible to the public, and where fishing is not permitted
  • Continuing to revegetate the McArthur River channel, leading to an increase in native fish numbers such as barramundi and sawfish
  • Engaging a variety of independent experts to help monitor and manage the challenges

The Independent Monitor report in December 2015 covered MRM activities from October 2013 to September 2014. It noted improved performance in a number of areas, including managing seepage from MRM’s tailings storage facility; revegetation of the McArthur River channel; and expanded environmental programmes for groundwater, dust, soil, and marine/aquatic environments. 

Throughout all our activities, we have continued to engage openly and regularly with all our key stakeholders. This includes the local community of Borroloola, a variety of independent scientific experts, a number of media organisations and Northern Territory government ministries that include the Department of Mines and Energy, the Department of Primary Industry and Fisheries and the Department of Health.
