Greenbushes Project — Talison Lithium
The Greenbushes pegmatites belong to the Lithium-Caesium-Tantalum family. The Greenbushes pegmatite deposit intrudes along a major northwest regional fault zone. It is approximately 2,525 million years old. The pegmatite consists of a large main zone over 3 kms long and up to 300m wide with numerous smaller pegmatite dykes and pods flanking the main body. The Greenbushes pegmatites are mineralogically zoned in a lenticular interfingering style along strike and down dip. The lithium zone is over
