Gunson Resources Limited (Gunson) is developing the Coburn Mineral Sand Project (the Project) in the
Gascoyne region of Western Australia (Figure 1). The Project comprises the excavation and processing of a
major low-grade mineral sand deposit immediately east of the Shark Bay World Heritage Property.
Approximately 2.8 Mt of Heavy Mineral Concentrate will be dry-mined from nine pits and processed on site
before transport to markets.
As part of the Environmental Impact Assessment (EIA) of the proposed Project, a Rehabilitation
Benchmarking Study (RBS) was conducted to demonstrate whether rehabilitation was possible by providing
examples of rehabilitation outcomes under similar conditions. This paper outlines the approach taken in
relation to this study and discusses the key outcomes.
