The 3600-2800Ma North Pilbara basement terrane consists of a series of ovoid multiphase granitoidgneiss domes bordered by sinuous synformal to monoclinal greenstone belts.

The Wodgina Greenstone Belt is a north to northeast plunging synclinal structure 25km long and 5km wide, preserved as a roof pendant separating the Yule and Carlindi granitoid complexes. It is composed principally of interlayered mafic and ultramafic schists and amphibolite, with subordinate komatiite, clastic sediments, BIF and chert. The komatiitic and metasedimentary units within the Wodgina area are tentatively correlated to the Kunagunarrina and Leilira Formations respectively.

Archean volcanic activity and sedimentation was followed by the intrusion of Archean granitic batholiths with consequent deformation and metamorphism of the sequence. Late stage granitic intrusions resulted in the emplacement of simple and complex pegmatite sills and barren quartz veins.

The Wodgina pegmatite district contains a number of prospective pegmatite groups, including the Wodgina Deposit.

The Wodgina lithium mineralisation is hosted within a number of sub-parallel, sub-horizontal, northeast trending pegmatite intrusive bodies which base of the massive pegmatite apparently with a dip at between 5° to 30° to the west-southwest.

At this time individual pegmatites vary in strike length from approximately 200m to 400m. The thinner near surface pegmatites vary from 10 ........

The Wodgina lithium operation is located 120 kilometres south of Port Hedland in the Pilbara region of Western Australia.

Ore is extracted via conventional truck and shovel method with preliminary drilling and blasting operations. Mining fleet includes 5 drill rigs, 3 excavators and 8 houl trucks. Final pit is designed of 310 metres depth with strip ratio of 3.1:1.

An upgrade of the existing processing facilities and site infrastructure at Wodgina has been completed to support a 750ktpa spodumene plant producing 6.0% spodumene concentrate. This plant, currently complete with train 1 successfully commissioned, will be delivered in three trains, each with a capacity of 250ktpa.
- The plant design was based on representative metallurgical tests on samples from the pit which have routinely been validated during the DSO operations.

The processing plant consists of:
- A three-stage crushing circuit – primary crushing, secondary crushing, highpressure grinding rollers (HPGRs) with capacity of 10mtpa.
- A modular wet processing plant – three parallel trains each producing 250ktpa of spodumene.
- Ball milling, de-sliming and iron removal stages.
- A conventional spodumene flotation circuit.
- Filtration of the spodumene concentrate to <10% moisture for transport to Port Hedland for shipping.
