Assays from recent RC drilling confirm narrow intervals of lithium mineralisation with

grades up to 1.75% Li₂O at the Eastern Prospect, with a much broader pegmatite 55m

intercept at the Central Prospect providing a vector for follow-up drilling.


  • Maiden first-pass Reverse Circulation (RC) drilling program completed at the 100%- owned Tambourah Lithium Project in the Pilbara region of Western Australia.

  • The drilling intersected multiple narrow lithium-bearing pegmatites, with intercepts including:

    • 5m @ 0.69% Li₂O from 36m in TARC002, including: 2m @ 1.44% Li₂O from 38m

    • 3m @ 0.45% Li₂O from 147m in TARC008, including: 1m @ 0.84% Li₂O from 148m

    • 2m @ 0.72% Li₂O from 24m in TARC012, including: 1m @ 1.07% Li₂O from 25m

  • The drill program was extended from a planned 3,800m program to 4,093m comprising a total of 20 holes.

  • Encouragingly the only hole targeting a geophysical target intersected a substantial width of pegmatite (55m down-hole), opening up the large Central Prospect area as a priority search space for follow-up drilling.

Trek Metals Limited (ASX: TKM) (“Trek” or “the Company”) is pleased to advise that assay results from its maiden Reverse Circulation drill program at the 100%-owned Tambourah Lithium Project, located ~70km south-east of the world-class Pilgangoora lithium deposit in the Pilbara region of Western Australia, have confirmed the presence of fertile lithium-bearing pegmatites.

Trek’s CEO Derek Marshall said: “Intersecting significant lithium grades in pegmatite during our maiden drill program demonstrates the lithium fertility of the Lithium-Caesium-Tantalum pegmatite system we have identified at Tambourah. The key now is to identify a structural setting that may have allowed for a significant accumulation of this high-grade material.

“Several holes were added into the program, including one into a geophysical target which has returned a significant down-hole width of pegmatite, much greater than was observed on the surface.

“The success of this hole has provided a method of targeting thicker accumulations of pegmatite in this fertile greenstone belt. The significant grades returned in this first batch of samples have elevated the prospectivity of the greater Tambourah region, although we have further work to do refine our exploration targeting and vector into thicker, high-grade zones of spodumene mineralisation. We look forward to updating the market on the upcoming exploration plans at the Tambourah Project.”
