SnapshotThe Ngungaju Plant is part of the Pilgangoora Operation.

Pilbara Minerals Ltd. planned to place the Ngungaju Plant into care and maintenance from December 1, 2024, as part of its strategy to consolidate processing at the Pilgan Plant in response to market conditions.

Looking ahead to 2025, the Ngungaju Plant is expected to remain in care and maintenance, with ongoing readiness for a full ramp-up within approximately four months once market conditions improve.

  • Pegmatite

Summary:

Altura’s Pilgangoora Lithium Project occurs at the southern end of a zone of pegmatite intrusive dykes within the synformal Pilgangoora greenstone belt. The pegmatites are hosted within amphibolites which have a mafic and ultramafic volcanic origin. A total of 13 mineralised pegmatites have been identified and these occur as a set of stacked lodes generally striking 010 030oNNE and dipping 25-40oESE. The dykes generally range from 8-14m thick however there are areas where the pegmatites form lenticular pods and are much thicker (up to 64m).

Based upon the completed drilling, the pegmatites appear to be confined to a NNE trending corridor which is approximately 1600 metres long (north to south), 550 metres wide (east to west) and 450m deep. Mineralisation is present at surface for some lodes with most mineralised lodes starting from within 10m of surface.

The mineralised pegmatites are located approximately 1km east of a granite contact. There are several barren pegmatites located in the zone between the granite contact and the mineralised pegmatite zone. The granite contact and barren pegmatites were identified via sterilisation drilling carried out for the proposed infrastructure and waste dump areas.

The reason for this structural and or geological control within the deposit area is not fully understood however the distance from the granite contact is such that mineralisation in the pegmatite is confined to lithium and rubidium (almost wholly reporting in spodumene and muscovite respectively) with relatively low values for tin and tantalum or other associated minerals.
