Rehabilitation at the Duketon South Operation

MACA has been undertaking rehabilitation at the Duketon South Operation since 2010. At this Regis Resources Project, MACA executes gold mining services, inclusive of landform profiling, topsoiling, ripping, seeding and drainage works.

Final landform construction is staged progressively on waste dumps and decommissioned tailings facilities across the operations. For final ripping of dump surfaces, a “winged keel” dozer ripper tyne is used to increase infiltration and reduce the likelihood of erosion occurring. The team also installs rock-pile habitats which supports the project’s long-term biodiversity efforts.
