Aruma Resources Limited (ASX: AAJ) is eyeing a development pathway following 12 confirmed intersections of 1.5% lithium-rubidium at the Mt Deans Lithium-Rubidium Project near Norseman, in the lithium corridor of south-eastern Western Australia.
The news follows initial pleasing results in November, where high-grade rubidium up to 1.43% with an average of 0.77-0.96% Rb2O had been confirmed over the first two of the program’s 21 RC holes – plus results from 7 re-assayed historical holes.
The drilling has confirmed and extended the lithium and high-grade rubidium intersected in multiple pegmatites in Aruma’s first phase of drilling in the central part of the project area and a subsequent rock chip sampling program,” the Company said.
“Based on the continuing positive results from its drilling and exploration activities at Mt Deans, Aruma may look to identify micaceous pegmatites with high-grade (>1.5% Li2O+Rb2O) Lithium- Rubidium-Cesium-Potassium ore, which, conceptually, may potentially be capable of being concentrated using simple froth flotation/gravity circuits to produce a saleable lithium-potassium concentrate, with valuable rubidium and cesium by-products with possible tin and tantalum gravity concentrates.”

About the Mt Deans Lithium-Rubidium Project
The 100%-owned Mt Deans Project (P63/2063) is located in the Mt Deans pegmatite field within the Eastern Goldfields Terrane of the Yilgarn Craton, approximately 170 kilometres south of the major regional centre of Kalgoorlie and about 10 kilometres south of the mining town of Norseman.
The Project sits within the lithium corridor in southeast WA, which hosts multiple significant hard-rock lithium projects. It is interpreted to sit within the same host rocks and structures
as the significant nearby Mt Marion, Bald Hill and Buldania Lithium Projects.
