Mine Rehabilitation

We strive to lessen the impact of our mining operations by minimizing the environmental footprint for each mine. This includes minimizing the land disturbed for mining and progressively rehabilitating disturbed areas that are no longer required for operations.

Our goal is to maintain a corporate-wide running five-year average ratio of 1:1 or better (meaning less than one) for active mining disturbance (excluding long-term infrastructure) to mine rehabilitation. This will manage net expansion in the area of land disturbed.

The ratio for the 2015 to 2019 period was 0.97:1, which indicates we had a larger area rehabilitated or handed over compared to new disturbance. We expect the ratio to decrease as more areas at our closed mines in Suriname are returned to the Suriname government after rehabilitation.

Case Studies

    Advanced Technology Meets Mine Rehabilitation Assessment

    Our team in Australia is using remote-sensing technologies to help evaluate bauxite mine rehabilitation efforts, which span thousands of hectares within the jarrah forest of southwest Australia. The task can be challenging due to the size of the area, but these technologies look to improve this important task.

    Protecting a Western Australian Icon

    A partnership between BirdLife Australia and Alcoa Foundation is working to reverse the decline of a well-loved species of birds in Western Australia. Three black cockatoos—the Baudin’s and Carnaby’s black cockatoos and the forest red-tailed black cockatoo—are currently listed as either endangered or vulnerable.
