Slide 5: Ti Tree Project
55 73 TI TREE PROJECT 3 Li Cs Ta Purpose? In search of Lithium-Caesium-Tantalum (LCT) pegmatites Prospectivity? The best place to make a discovery, is beside a discovery How? Using established best-practices in lithium exploration
Slide 6: Ti Tree Project
Ti Tree Project • Comprises 3 exploration VOLTAIC licences (212 km2) Ti Tree (North) VOLTA CORRIDOR • Tenure overlays an VOLTA2 TARGET 19 km prospective LCT interpreted prospective target zone corridor of lithium-bearing pegmatites where recent RDT exploration efforts have Yinnietharra Lithium disco
Slide 7: Where is the Lithium coming from?
Where is the Lithium coming from? • Most likely, the major granitic bedrock system, the “Thirty Three Supersuite” - named after the Thirty Three River VOLTAIC Ti Tree (North) • There is an interpreted 80 km ‘corridor’ from the bottom of RDT Ti Tree South to the top of Ti Yinnietharra Lithium Tree No
Slide 8: How do we know this?
How do we know this? • Geochemical “fertility” analysis - the established science behind Lithium exploration. Pioneered by P. Cerny in the 1980s • Hardrock Li-Cs-Ta (LCT) deposits are typically hosted within pegmatitic rocks. Pegmatites evolve from ‘parent’ granitic rocks and are most typically “bar
Slide 9: Pegmatites at Ti Tree
Pegmatites at Ti Tree • Widespread throughout tenure • Outcropping at surface • Are they “fertile” (LCT enriched)? • Yes, as confirmed from maiden surface sampling campaign (see Appendix for details) • ~ 230 samples collected • Active follow-up in progress
