Iluka’s land management and rehabilitation efforts are aligned with leading practice and undertaken in a socially and environmentally responsible manner.

Every site has an overarching Closure Framework which consists of a number of closure components that can be contained in a singular closure plan or maintained in multiple documents in a central database.

Closure components are at a level of detail that is appropriate for the phase and current understanding of site conditions. These components are reviewed as required to reflect changing circumstances of a site such as transitioning of each project phase, changes in operational activities, mining methods and site layout or processes.

Planning for closure commences at the feasibility phase and is maintained throughout the life of the asset – from feasibility studies, execute, operations, closure through to close out, evolving over time as more information becomes available.
 
During the early phases of a project, closure planning identifies uncertainties related to closure objectives or criteria, and potential rehabilitation research or engineering required to address these uncertainties. A detailed handover of all closure components occurs at the transition of each phase of a project.

Iluka prefers progressive rehabilitation during operations as it:

  • minimises the final closure footprint;
  • assists with understanding and evaluating risks;
  • identifies knowledge gaps;
  • targets research and development of specific completion criteria; and
  • refines closure provision estimates. 

In 2017, a performance target was set for all sites to have closure plans in accordance with the internal standard in addition to legislative requirements by the end of 2018.  This target was met with all sites implementing the Closure Framework and having closure plans in place.

During 2018, the rehabilitation of 806[1] hectares of land in Australia, the United States and Sierra Leone was completed. 888 hectares of land was disturbed in 2018.  Construction of the Cataby mine equates to 60% of the disturbance during 2018 whilst 26% is attributed to opening up the Ambrosia area ahead of the mine move from Jacinth to Ambrosia at J-A mine. 
 
Iluka continues to refine and improve our land clearing and rehabilitation information with improvements in technology. In 2018 substantial effort was spent to ensure up to date land clearing and rehabilitation information for the Sierra Rutile operations. This included the integration of a combination of spatial information technologies such as surveys, Geographic Information System (GIS) mapping and aerial imagery.  It provides the ability to verify independently data via aerial photography. Definition standardisation across all jurisdictions was also undertaken. The total open area reported change, from 4,727 hectares in 2017 to 10,632 hectares in 2018, is largely due to the addition of Sierra Rutile to the dataset.

[1] 741 ha  was reported as rehabilitated in the 2018 full year results presentation. This included demolition areas (13ha) and did not include areas rehabilitated at US Florida operations (78ha).
