Multiple lithium targets identified at the Pioneer Dome Lithium Project

Structural geological study has assisted in defining 40+ targets across 450km2 of project tenure, highlighting the substantial exploration upside outside of the current 11.2Mt lithium Mineral Resource 1 .


  • Structural Interpretation: Over 40 targets have been identified and ranked with field checking now in progress. The results of the structural geological study have been incorporated with other exploration data including geophysical surveys, soil geochemistry, drilling, and field mapping, allowing targets to be defined and ranked by an external consultant (Xirlatem).

  • Field-checking has already identified several new pegmatites including a north-south trending pegmatite sub-crop up to 15m wide to the east of PEG004, located approximately 13km south of the Dome North LCT pegmatites and 5km north of the Sinclair LCT pegmatite. Fieldwork will continue with the aim of delineating a drill plan for implementing in March Quarter 2023.

  • Two large soil programmes are also underway over areas containing two priority structural targets that have not previously been soil sampled.

  • The updated Dome North Mineral Resource is expected to be completed in three weeks. Together with metallurgical test work results, this will underpin the Scoping Study that is currently underway and expected to be completed by mid-January 2023.

Essential Metals Managing Director, Tim Spencer, said: “While pressing ahead with our strategy to get the Dome North lithium Mineral Resource (11.2Mt @ 1.21% Li2O)1 ready for development, we are very much focussed on making new lithium discoveries across what is a very large and prospective land position in WA’s premier lithium corridor. This corridor already hosts 5 of Australia’s 14 lithium (spodumene) Mineral Resources within a 90km radius, including our own. This is an exciting time for Essential as we advance our development to the next level and begin to unlock the broader potential of the Pioneer Dome Project.
