Aruma Resources Ltd (ASX:AAJ) has kicked off a new phase of drilling at the Mt Dean Lithium-Rubidium Project in Western Australia, intending to drill up to 1,800 metres over 12 holes in the search for a mineralised lithium-rubidium body.
This phase of the program is intended to further investigate results from an earlier round of drilling and rock chip sampling, which returned grades of up to 1.96% lithium, 1,550 parts per million caesium and 1.42% rubidium.
Initial observations indicate there are several pegmatites in the northern section of the project, which may warrant more drilling, especially given the high lepidolite content, a key indicator of lithium-rubidium mineralisation.
Specialised drill rig secured
Aruma secured a specialised ‘small footprint’ blast-hole reverse circulation drill rig for this phase of activities, intended to minimise disturbance of vegetation and allow for tangential drilling for better access.
The access tracks at Mt Deans run north-to-south. The company intends to leverage the specialised blast-hole rig to drill east-west holes, to test the extent of the thick lithium-rubidium dyke intersected in previous drilling at the project.
