Mt Edon: Morella–Elevra JV pegmatite hits and open-pit potential for mine planners
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Elevra Limited and Morella Corporation have completed reverse circulation drilling at the Mt Edon rubidium–lithium project in Western Australia, reporting strong pegmatite intercepts that confirm the continuity of the mineralised system. The JV is targeting rubidium- and lithium-bearing pegmatites within the southern portion of the Paynes Find greenstone belt, using RC to define geometry and grade distribution ahead of potential resource estimation. Results will guide follow-up drilling, with particular focus on thicker pegmatite zones that could support open-pit extraction and simple crush–grind processing.
Technical Brief
- For similar rubidium–lithium pegmatites, early structural modelling of dyke swarms is becoming standard for pit optimisation.
Our Take
Rubidium appears in only a small fraction of the 113 keyword‑matched pieces in our database, so Mt Edon’s pegmatite results place Elevra and Morella in a relatively niche but potentially high‑value segment compared with mainstream lithium‑only projects in Western Australia.
For Australian lithium operators already established in WA, a rubidium‑bearing pegmatite system at Mt Edon could signal future competition not just in spodumene tonnes but in securing specialised processing and offtake channels for rubidium‑rich concentrates.
