Ann: Flotation Test Work and Initial CDL Metallurgical Results, page-2

Preliminary Flotation Test Work Update and Initial Carriere de l’Este Metallurgical Results
Highlights

• Phase 2 metallurgical initial test programme (Flotation) completed
• Lithia flotation recoveries were consistent averaging 69% recovery after
adjusting for losses to slimes, magnetic separation and flotation tailing
• Concentrate grades from 6.1% to 6.4% Li2O were all above the Company’s
target of 6% Li2O spodumene concentrate (“SC6.0”)
• Iron (Fe2O3) levels were all within a SC6.0 concentrate specification with
significant upside demonstrated in Test-06 and Test-07
• A marked decrease in Fe2O3 content was achieved by increasing the magnetic
field intensity of the WHIMS process presenting as a further upside
optimisation
• Initial metallurgical test work completed on 100kgs of quarter drill core from
Carriere de l’Este (“CDL”)
• Randomly sampled high grade sections generated a 2.37% Li2O bulk sample
head grade
• DMS100 testing on CDL samples generated a SC6.2% with a recovery of 55%
at 5.6mm crush size and a SC6.3% with a 66% recovery at 3.35mm crush size

Nice !!!
