Mount Edon

Mount Edon

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 (LCT) 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 (the current Mining Lease area). 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). The northern Wydgee tenement E59/2326 has had no lithium exploration work undertaken. It has a known beryl-bearing pegmatite that was exposed and mined for beryl in 1971 over a 35m long and 3m wide area. The pegmatite is hosted with a coarse-grained quartz monozonite on the southern end of the Wydgee-Meekatharra greenstone belt.
