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.

Fortescue Metals Group (FMG) undertook a significant stream sediment sampling program that identified a large area with anomalous lithium, and other pathfinder elements such as caesium, rubidium and tantalum (Figure 1 & 2, refer JORC Table 1 – WAMEX A124826) on what is now Trek’s tenure. The historic data has highlighted the potential for lithium-bearing pegmatite mineralisation on both of Trek’s Tambourah Project tenements (E45/5484 & E45/5839 – see Figure 2) in the Pilbara region of Western Australia.

Rock chip samples taken by FMG also support the LCT potential with sample J576120 returning an assay result of 1.06% Li2O within E45/5839 (Figure 1, refer WAMEX A124826 & ASX: TKM 26th May 2022).

Trek previously reported exceptional high-grade results of up to 178g/t Au from rock chip samples taken preliminary reconnaissance fieldwork on E45/5484 in 2021. The prospectivity of the area is supported by other high-grade results from nearby samples including 13.0g/t Au and 5.79g/t Au (refer ASX: TKM 2nd August 2021). There are at least 13 known gold occurrences and old mining workings located on the project.
