Our Approach

We ensure that our waste and product materials generated from mining and processing are handled, stored and disposed of appropriately. The most substantial waste stream is mineral waste.

Mineral waste is defined as excess material removed from the mine void in order to reach the ore body and remaining materials after the extraction of mineral from ore during processing. All mineral wastes are handled in accordance with the Evolution Sustainability Performance Standards and licence conditions.

Operations manage waste in accordance with a site-specific Waste Management Plan. Non-hazardous waste streams such as cardboard, glass and plastic are recycled, and general household waste is diverted to landfill.

Each operation is unique in terms of potential for acid mine drainage (AMD), neutral mine drainage (NMD) and saline drainage (SD) impact on the surrounding environment. Where Potentially Acid Forming (PAF) waste rock is suspected or known to occur, the operation implements progressive rehabilitation activities to ensure the receiving environment is not impacted by leachate or potential failure.

Future Focus

Evolution have partnered with external organisations to address:

  • Non-road diesel emissions
  • Energy
  • Water security – reuse of water
  • Tyre recycling
  • Unlocking the value of waste rock and tailings

Non-Mineral Waste

Responsible management of non-mineral waste at our operations is formalised through the implementation of comprehensive waste management plans. These plans specify how the different types of waste produced by our activities are to be managed, including identification of opportunities for waste minimisation, recycling and reuse.
