Advanced Australian lithium developer, Core Lithium (ASX: CXO), has announced much improved metallurgical performance from recent testwork conducted on representative bulk samples of spodumene pegmatite core recently drilled from the BP33 deposit within the Finniss Lithium Project near Darwin in the NT.
HIGHLIGHTS:
-
Excellent recoveries from recent gravity separation test work on spodumene pegmatite from BP33
-
Exceptional Concentrate Quality Produced at High Recovery
-
Concentrate Grade of 6% Li2O
-
Low Impurities <0.5% Fe2O3
-
65-72% Recovery
-
-
Improved results achieved from coarse 6-10mm crush size and coarser cut-off size
-
Finniss’ superior quality, low-iron, coarse lithium concentrate differentiates Core in the quality-focussed battery and EV supply chain
-
Further test work results expected in April
-
Finniss Resource estimates expected in coming weeks ahead of Feasibility Study update in Q2 2020 targeting significantly increased mine-life and substantially improved economics
These new results from the high lithium grade and low iron content ore body at BP33 improve on previous test work results in regard to producing exceptional quality lithium concentrate at better lithium grades, lower iron content, at higher recovery and at a larger crush size.
Core believes that the high-quality, low-iron, coarse Finniss lithium concentrate will be differentiated in a lithium battery and EV market focussed on demand for exceptional quality materials supplied from ethical and sustainable sources.
Testwork included a number of larger scale tests using the 100mm Dense Media Separation (DMS) cyclone circuit with results demonstrating the robust metallurgy of the BP33 deposit.
