SUSTAINABILITY Waste management

Waste management

Process plant tailings waste and waste rock (or mineralised waste) are two of the most significant by-products of mines. We are committed to responsibly managing these waste streams to minimise their impact on the environment and our host communities. We are working to achieve this by:

  • Using waste rock material to support the construction of TSF embankments or in closure-related activities
  • Backfilling tailings material in redundant open pits, which reduces the waste footprint
  • Co-mingling of tailings and waste rock to mitigate potential pollution and create more stable landforms
  • Operate tailings and waste rock facilities toward closure and align with GISTM requirements
