Wyloo Dome Gold Project
Lithium, Caesium & Tantalum (Li-Cs-Ta)
The Tambourah Project (E45/5484 & E45/5839) is considered highly prospective for gold & Lithium Caesium Tantalum (LCT) pegmatite deposits. The Project hosts the Western Shaw Greenstone Belt, which occurs on the eastern limb of an anticline folded around the Tambourah Dome. The greenstone rocks comprise Archean-aged metavolcanic, metasedimentary, and various granitoids that occur as large plutons and smaller intrusives.

Summary
The Tambourah Lithium Project is located 70km south-east of Pilbara Minerals’ (ASX: PLS) world-class Pilgangoora lithium mine site in the Pilbara region of Western Australia (Figure 3).
Trek’s extensive landholding at Tambourah comprises two Exploration Licences (E45/5484 & E45/5839) which are 100%-owned by ACME Pilbara Pty Ltd, a wholly-owned subsidiary of Trek Metals Ltd.
The Project encompasses the central portion of the 15km long Western Shaw Greenstone Belt, which occurs on the eastern limb of an anticline folded around the Tambourah Dome. The greenstone rocks comprise Archean-aged metavolcanic, metasedimentary, and various granitoids with associated pegmatitic phases.
High-grade lithium assays of up to 3.07% Li2O confirm significant potential at Tambourah. Outstanding rock chip sample results returned from across multiple spodumene-
bearing pegmatite dykes at the Tambourah Project. Multiple recently identified spodumene-bearing pegmatite dykes confirmed by laboratory assay to contain high-grade lithium, with results including:
-
3.07% Li2O in TKL0045
-
2.69% Li2O in TKL0042
-
2.36% Li2O in TKL0095
-
2.28% Li2O in TKL0044
-
2.11% Li2O in TKL0083
Historic rock chip results highlight the presence of a large, fractionated LCT pegmatite swarm prospective for lithium, with good correlation to both the previously reported anomalous stream sediment data and mapped pegmatites on the ground.
Heritage surveys at the Tambourah project were completed in April of 2023 covering high-priority lithium-bearing pegmatites at the Eastern and Central Prospect areas.
Trek Metals maiden drilling campaign at Tambourah commenced on the 26th of June 2023. The initial 3,800m Reverse Circulation (RC) drilling program has been designed to follow-up the high-grade lithium spodumene-bearing pegmatite dykes identified at surface in the Eastern Prospect area, where high-grade rock chip results were returned last year.
The program will also test the high-priority Central Prospect area, where lithium-caesium-tantalum (LCT) pegmatites and fractionated fertile pegmatites are interpreted to be located within or close to the lithium
zone.

Summary
Trek Metals is pleased to advise that it has signed an agreement with Strike Energy Limited (ASX: STX – “Strike”). Strike is proposing to develop the Mid-West Geothermal Power Project and as part of this proposed development, Strike has applied for a Geothermal Exploration Permit, application pending.
The Agreement forms part of a regional exploration initiative under which Trek has been assessing exploration tenure in Western Australia where there may be an opportunity to explore for lithium-in-brines due to the presence of favourable target horizons that are being exploited for geothermal energy.
Trek has a strong focus on exploring for battery metals across its portfolio in the Pilbara region of WA and, while its major focus is on hard rock lithium, nickel-copper and manganese projects, it is also considering value-add opportunities in exploring for lithium-in-brines.
Trek has three granted and two pending mineral exploration licenses held by 100% owned subsidiary Anaheim Pty Ltd in the Midwest region which overlap Strike Energy’s Geothermal Power Project – which is based on the Kingia Sandstones target horizon.
In the event that Trek identifies a sufficient quantity and quality of lithium within the brine sample, the two parties will then consider a potential further agreement that may govern the next stage of a potential project, including further drilling of wells and testing for lithium brines; and undertaking further investigation on the interaction between direct lithium extraction (DLE) technology and geothermal power projects.
