SnapshotThe Wimmera Project development involves the mining and beneficiation of a fine-grained heavy mineral sands ore body in Western Victoria for the potential long-term supply of rare earths and zircon.

A Preliminary Feasibility Study (PFS) was completed in early 2023 and Iluka’s Board approved $30 million funding for a DFS in February 2023.

A significant field development program commenced in Q1 2024. The program includes additional resource drilling, geotechnical test pits, cultural heritage test pits, and further hydrogeological investigations.

Environmental approvals processes are progressing, alongside process engineering and mine design.

In parallel, Iluka is continuing the process design of the zircon purification process, with the goal of demonstrating commercial viability via a demonstration plant. Zircon revenue has not yet been accounted for in Wimmera’s Ore Reserve.

Deposit type

  • Mineral sands
  • Sedimentary

Summary:

The WIM100 deposit is located along the south eastern margin of the Murray Basin geomorphological province in the state of Victoria, Australia. The zone of mineralisation grading in excess of 1% HM is hosted in a single tabular horizon within the Loxton Parilla Sand (LPS) geological unit. Mineralisation extends over a north-south strike distance of 9.5km and an east-west distance of 3.5km. The mineralisation varies from 3 to 20m in thickness averaging 9.5m and resides beneath 8 to 20 m of unmineralised sediment.

WIM100 along with adjacent deposits WIM50 and WIM50 North are located along the southern margin of the Murray Basin, a shallow, intracratonic basin of Cainozoic age. The basin covers a saucershaped area around 300,000km2 extending into eastern South Australia, south-western New South Wales and north-western Victoria. It is flanked by uplands of Proterozoic and Palaeozoic rocks.

The Murray Basin contains a succession of freshwater, marine, coastal and continental sediments. The latest marine transgression-regression event resulted in the deposition of the Late Miocene to Late Pliocene Loxton-Parilla Sand (LPS). These sediments were deposited in shallow marine, littoral environments with some terrestrial fluvial intercalation and are characterised by fine to coarsegrained, generally well sorted sand with minor clay silt and gravel.

Dimensions
The WIM100 mineralisation has a north-south strike extent of about 9.5 km, an east-west across strike extent of about 3.5 km. The mineralisation varies from 3 to 20 m in thickness and averages about 9.5m in thickness. The mineralisation is covered by an average thickness of about 15 m of non-mineralised Shepparton Formation and coarse grained LPS with depth to mineralisation varying from about 8 m to 20 m.
