KCGM plans to rehabilitate waste rock dumps and tailings storage facilities as soon as these areas become available, this is known as progressive rehabilitation. The benefits of progressive rehabilitation include the early establishment of vegetation, which reduces dust levels and improves visual surroundings. In addition this also results in a significant reduction in the amount of rehabilitation required when mining is completed.
Natural ecosystems in the region are studied to determine the best range of plants for soils and slopes on the new landforms. This is reflected in the mixes of plant seed for the rehabilitation. The rehabilitation done by KCGM aims to establish plant communities that will be stable for the long-term.
Monitoring, research and ongoing improvements to revegetation methods are an important part of this process.
