This acquisition complements MRC’s strategic focus on battery minerals with development of the Munglinup Graphite Project located near Esperance, as well as the existing Yandeyarra Lithium Project southeast of the Pilgangoora lithium field being mined and developed near Port Hedland.
The Mount Edon pegmatite field hosts numerous lithium-cesium-tantalum pegmatites and is strategically located close to existing infrastructure, making it an excellent exploration and mine development target.
The mining lease area has proven lithium-rich zones associated with the pegmatites, as well as historical mining for tantalum (manganotantalite and alluvial deposits: 1969-1974 Mt Edon, Alfredo Pieri), beryl and microcline feldspar (Goodingnow pits, 1975-1978, Mark Calderwood). The zonal nature of this pegmatite field has previously been defined with microcline feldspar, including amazonite, in the east (historically mined) and more complex albite-rich zones containing niobium and lithium in the west. Lepidolite-zinnawaldite (lithium mica) rich pegmatites have been previously identified. Historical reported lithium grades of up to 2.2%Li2O5 have been found on the Mining Lease (M59/714, Pancontinental Mining, 1980s, and Haddington Resources/Australian Tantalum Ltd, 2002).
