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, because of the joint venture with EV Metals, 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.
The first diamond core drilling has been received from the ongoing drilling campaign at the Rio region 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). Assays have now been received for 6,076 samples, with a further 2,475 samples awaiting assays. To date, first pass sampling, has now covered approximately 25-30% of the project area with additional sampling planned for the 2023 field season.
The geochemical sampling program has been successful in defining a major new geochemical anomaly that exceeds the size of the geochemical anomaly surrounding the Rio lithium pegmatite. The new anomaly (“Cielo”) presents a major new lithium target to be drill tested.
