Winsome Resources (ASX:WR1) has received outstanding metallurgical results from test work on composite samples from the company’s Cancet and Adina projects in Quebec, Canada.
Heavy Liquid Separation (HLS), with batch flotation tests, were performed on three composite samples prepared from split drill core.
Exceptional metallurgical results were achieved in the test work undertaken on two lithium-bearing composite samples from the flagship Cancet project and one composite sample from the Adina project.
Samples were sourced from split drill core from the Phase 1 drilling campaign which was previously completed at Cancet.
Hole selection was guided by the requirement to ensure the metallurgical testing would provide a representative view of the deposit at Cancet.
HLS tests achieved global lithium recoveries ranging from 68% to 83% (interpolated to 6% Li2O grade). Overall lithium recoveries, when combining results obtained from HLS and batch flotation testing, ranged from 85% to 94% with spodumene concentrate lithia grades ranging from 5.96% to 6.27% Li2O.
Initial test work results show the potential for a dense media separation (DMS) processing route which would lessen environmental impacts, enable quicker approvals and subsequently, accelerate time to market.
Future test work will further investigate iron rejection in the flowsheet; the impact of host rock dilution on metallurgical performance; and optimisation of the flotation conditions. Metallurgical test work was undertaken at SGS Canada Inc. in Lakefield, Ontario.
“Results from the metallurgical test work on composite drill core from our Cancet and Adina projects are outstanding,” Managing Director, Chris Evans, said.
“The latest results significantly build on test work done previously by MetalsTech, which tested a Cancet composite with Heavy Liquid Separation (HLS). We have expanded the testing to include Adina and flotation test work on samples from both projects.
“The recoveries are exceptional with just HLS as a standalone and are improved further with flotation test work. They show Cancet ore can potentially be beneficiated to a 6% Li2O concentrate with just Dense Media Separation (DMS). This will result in a lower environmental impact with less comminution (crushing), power and chemicals needed, lower capital cost and quicker approvals, which should mean an acceleration to market.” For further information please visit: https://winsomeresources.com.au/
