The Mt Deans Lithium Tantalum Project
The Mt Deans lease (P63/2063) was granted in September quarter 2019. The lease was subject to an earn-in JV with Lithium Australia NL which ceased in mid 2020, with the lease reverting to 100% Aruma. Aruma holds a positive view of the lithium tantalum REE potential of the lease area with previous work having identified swarm pegmatites over 1km in length.
The Mt Deans Project covers an area of 1.44km2 in the Mt Deans pegmatite field, which is part of the Eastern Goldfields Terrane of the Yilgarn Craton. The Project is located approximately 190 kilometres north of the Esperance port, 170km south of Kalgoorlie and approximately 10 kilometres south of the mining town of Norseman (Figure 1).
