The composite grade was 1.53% Li₂O, which occurred mainly as spodumene

HLS testwork determined that -9.5 mm would be the optimum crush size for feeding a DMS plant. (The HLS results at a
crush size of -9.5 mm showed that 54% of the lithium in the feed was distributed in the SG 3.0 sink with a very high grade of
7.22% Li₂O)
HLS projections were confirmed in a short continuous DMS pilot plant campaign
DMS + magnetic separation on the 2nd pass DMS sinks produced a final spodumene concentrate grading of 6.04% Li₂O with
only 0.53% Fe2O3
Lithium recovery rate was 70%
•
These strong results were achieved without the use of flotation technique
