SnapshotMining development has been ongoing at Wiluna West C4 since 2020.

In July 2022 a Binding Term Sheet to grant the mining rights to C4 to Gold Valley Iron Ore Pty Ltd. was signed.

Gold Valley acquired the Wiluna West Iron Ore Project including the C4 Project in March 2024.

In October 2024, Gold Valley exported its maiden shipment of iron ore through the Port of Esperance.

Production results have not been available since 2023.

Summary:

The Wiluna West project covers a 25 km strike length over the Joyners Find Greenstone Belt, near the northern margin of the Yilgarn Craton. The Joyners Find Greenstone Belt is a narrow (5 km to 10 km) north-south striking greenstone belt comprising low ridges of BIF (in the central and eastern portion) intercalated with mafic and ultramafic schists with minor chert and clastic sediment horizons. The Joyners Find Greenstone Belt strikes north and dips steeply to the west. Folds developed during the D2 deformation event are observed in the BIF ridges as tight to isoclinal folds oriented north-south with west dipping axial planes. The BIF ridges are variably deformed and intensely folded.

Two regional dextral shear zones are recognised: the Joyner’s Find Shear Zone (JFSZ) strikes to the north through the centre of the belt and is parallel to the lithological strike; and the Brilliant Shear Zone (BSZ) which is oriented north-northwest.

There are three main Banded Iron Formation (BIF) units which form ridges within the project area (Units A, B and C). High grade DSO hematite mineralisation occurs within units B and C with grade occurrences of up to 69% Fe. Iron mineralisation occurs within BIFs surrounded by inter-bedded mafic and ultramafic schist units. The two main ridges show distinctive mineralisation styles with B ridge showing a much lower proportion of remnant bedding and generally a significantly higher portion of haematite especially in the top 20 m. Mineralisation of the B ridge is also much more continuous along strike occurring semicontinuously for over 15 km. The mineralisation on the C ridge typically occurs in a series of pods of up to 20 Mt separated by poorly or unmineralized BIF. These pods appear to be controlled by structural deformation and are generally confined to the western side of the formation.
