SnapshotMining ceased at Eneabba in March 2013. Iluka routinely produces the rare earth bearing minerals monazite and xenotime as by-products of mineral sands processing activities. In 2019, Iluka initiated the Eneabba Project to process stockpiled monazite material.

Phase 1 of the development commenced operating in 2020 and produces a mixed monazite-zircon concentrate. Phase 2 further processes this product to produce a 90% monazite concentrate – a direct feed to a rare earths refinery; and a separate zircon-ilmenite concentrate. Phase 2 was completed in June 2022.

Phase 3, a fully integrated rare earths refinery for the production of separated rare earths, received final investment approval in April 2022. The Eneabba stockpile comprises the rare earth minerals monazite and xenotime, produced as by-product from Iluka’s Narngulu mineral processing plant and stored since the early 1990s is going to be the initial feed source.

Summary:

The Eneabba Mineral Separation Plant (MSP) By-Product Mineral Resource is located within the Perth Basin however the material is made up of mineral sands by-product from Iluka’s Narngulu MSP. Being a minerals sands stockpile there is no geological structure. The stockpile physically presents as a fine grained sand and is approximately 300m in length, 150 wide and varies from 1 to 15m in thickness. The fine grained, dark brown to black material is easily distinguishable from the yellow clayey sand it resides on.

A half to one meter cap of orange brown, gravelly, clayey sand covers the resource. A mixed zone of the by-product and capping immediately below the capping with high HM grade in combination with elevated slimes and oversize is recognised, being defined in the resource estimation and reporting.

The tailings material comprises a mixture of ilmenite, staurolite, aluminosilicates, zircon and the rare earth bearing mineral ‘monazite’, a naturally-occurring radioactive material (NORM).
