Driving exploration for metals crucial to our clean energy future

Split Rocks

Lithium Project

The Split Rocks Project is located in the Southern Cross region in the Forrestania greenstone belt situated between Perth and Kalgoorlie. Zenith has been systematically drilling for gold within its 660 sqkm tenement specifically in the north-eastern corner where there have been strong indications of well mineralised zones.

More recently, a systematic drilling campaign has been undertaken to identify areas within the tenement boundary that are potential lithium targets.

This is an emerging lithium district given that it hosts the Wesfarmers/SQM joint venture at Mt Holland that contains 189Mt @ 1.5% Li2O.

Diamond core drilling to date from the Rio region has returned and has returned significant lithium results over two intervals totaling 49m thickness. The best of the results included:

  • 26m @ 1.2% Li2O, including 13m @ 1.9% Li2O in the upper zone
  • 23m @ 0.8% Li2O, including 8m @ 1.3% Li2O in the lower zone

 

During 2022 a total of 8,551 geochemical samples were collected across the Split Rocks project area comprised of both auger and soil samples with the sampling method determined by the regolith (nature of the materials present near surface).  All assay results from the 2022 sampling campaign have been reviewed, assessed, and integrated into Zenith’s Exploration Targeting System. This has resulted in the definition of 83 lithium targets (including Cielo and associated targets in the southern area of Split Rocks) as announced to the market on 7th December 2023.

Further target ranking is ongoing and will be used to determine the highest priority drill targets for the 2025 AC/RC lithium drilling campaigns at Split Rocks.
