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.
High-potential greenfields lithium exploration opportunity
Proven team with deep battery market experience
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.
