McArthur River Mine statement on zinc-lead concentrate spills

Media statement
Darwin, Australia
21 May 2021


MRM takes the protection of the environment very seriously. 

Any concentrate spill from road trains on the Carpentaria Highway is reported to the regulator and subject to a full investigation to identify the root cause and corrective actions.

As a result of recent investigations, we have spent time with our local road train haulage contractor company to review and reinforce a number of measures including:

  • inspection of all road trains on site and repair of faulty or defective trailer covers
  • enforcing a fill level for the loading of trucks
  • reinforcing with our contractors the need to maintain their trucks to the required standard, including the hydraulic trailer lids
  • providing reviser training courses for all our contractors’ truck operators
  • speed limiting of road trains
  • three separate inspections of each road train before leaving the mine site to ensure covers are correctly locked down and that no concentrate is on any external surface
  • installation of cameras at the site weighbridge in April to confirm cleanliness of trucks and trailers
  • regular inspections of public and site road surfaces

If a spill does occur, it is cleaned by an onsite response team to remove all concentrate and soils if affected. Testing undertaken to verify clean-up shows that levels are within health and environmental guidelines.
