The Wimmera Project's primary focus is the WIM100 deposit, one of a number of similar style, fine grained deposits located in the Wimmera and Mallee regions of western Victoria. The deposit is distinguished by the fineness of its mineral content, which is unsuitable for processing at Iluka’s Hamilton mineral separation plant. As such, the project encompasses the development of both mining activities and new processing facilities. The project is currently in definitive feasibility study phase (DFS).

Under the Environment Effects Act 1978 Iluka is required to prepare an Environment Effects Statement (EES) to assess the potential environmental impacts of the project. The EES will require Iluka to conduct a number of studies including, but not limited to, biodiversity and habitat, water catchment and hydrology, visual and environmental amenity, social impact and cultural heritage.

More information on the EES for Wimmera can be found on the Victorian Government's Department of Transport and Planning website.
