THE BOURSE WHISPERER: Cobre Montana (ASX: CXB) has completed producing lithium carbonate from lithium based mica concentrates over a continuous 10 day period fusing mica recovered the Lepidolite Hill deposit, located 55 kilometres south-west of Kalgoorlie, Western Australia.
The Lepidolite Hill deposit forms part of the Coolgardie Rare Metals Venture (80% Cobre and 20% Focus Minerals (ASX: FML)).
The testing involved a custom designed mini-processing plant operating under the supervision of Perth based Strategic Metallurgy.
Cobre indicated lithium carbonate of at least 99.5 per cent purity was produced.
Cobre explained the mini-plant operated for 10 days to produce lithium carbonate for the initial stages of commercial product evaluation.
The lithium carbonate produced during the course of the mini-plant run, will be sent to end-users for evaluation and independent product endorsement.
“Our plan to commence production of lithium carbonate for commercial evaluation by the end of June has been fulfilled with carbonate produced on a steady-state basis,” Cobre Montana managing director Adrian Griffin said in the company’s announcement to the Australian Securities Exchange.
“The ten day test has provided lithium carbonate for distribution to potential end-users but will also provide valuable process information for the design of larger test plants.
“The current program is a critical step towards commercializing disruptive technology for the production of lithium chemicals.
“This very successful test run has demonstrated the ability to process the most common lithium minerals, the micas, on a continuous basis.
“The know-how developed will be applied to other deposits currently under assessment in Western Australia and Western Europe.”
