Tabba Tabba Lithium Project

Project Overview

Pilbara WA

Tabba Tabba Lithium-Tantalum Project is an advanced lithium and tantalum exploration project on granted Mining Leases just 80km by road from Port Hedland, WA. It is nearby some of the world’s largest hard-rock lithium mines (47km by road from Pilbara Minerals’ 414Mt Pilgangoora Project and 87km by road from Mineral Resources’ 259Mt Wodgina Project).

Tabba Tabba was one of four significant LCT pegmatite projects in WA, previously owned by Sons of Gwalia. The others were Greenbushes, Pilgangoora and Wodgina which are now Tier-1 hard-rock lithium mines. Tabba Tabba is the last of these assets to be explored for lithium mineralisation.

Wildcat acquired Tabba Tabba in 2023. Nearly 40 outcropping pegmatite bodies were mapped on the mining leases but only the body hosting the Tabba Tabba tantalum deposit had been drilled and most samples not assayed for lithium, representing exploration upside in an emerging lithium region.

Wildcat commenced aggressive exploration and drilling, and defined a 3.5km long LCT (lithium-caesium-tantalum) pegmatite field hosting at least seven significant pegmatite bodies (Leia, Luke, Boba, Chewy, Tabba Tabba, Han and Hutt).

Leia has returned intercepts including:

• 180m @ 1.1% Li₂O from 206m (TARC148) (est. true width)
• 119.2m @ 1% Li₂O from 334.3m (TADD010) (est. true width)
• 105.3m @ 1.1% Li₂O from 213.7m (TARC259AD) (est. true width)
• 99.0m @ 1.2% Li₂O from 207.0m (TARC234D) (est. true width)
• 94.0m @ 1.0% Li₂O from 206.0m (TARC154AD) (est. true width)

Luke, a blind discovery sitting underneath Leia, has returned:

• 54.4m @ 1.2% Li₂O from 267.9m (TADD030) (est. true width) and
  – 20.5m @ 1.5% Li₂O from 297.5m and
  – 25.0m @ 1.2% Li₂O from 363.9m
• 61.0m @ 1.1% Li₂O from 227.0m (TARC350D) (37.8m est. true width)
  – including 31.0m @ 1.6% Li₂O from 228.0m (19.2m est. true width)

Wildcat’s discovery of Luke confirms this world-class system has more to offer. Our industry leading geological team continues to develop target ideas and concepts which gives rise to a higher probability of future discoveries. Drilling at Leia, Luke and other pegmatites (Hutt, Han and Chewy) continues.
