HYDROXIDE TESTWORK PROGRAM PROCEEDING FAVORABLY
• Lithium hydroxide testwork at SGS Lakefield is on schedule and proceeding well
• Delivery of hydroxide samples to prospective offtake partners will commence upon program completion
• Optimized flowsheet to underpin Chemical Plant PFS targeted for Q2 2020
Piedmont Lithium Limited (“Piedmont” or “Company”) is pleased to provide an update on the metallurgical
testwork program underway at SGS Labs (“SGS”) in Lakefield, Ontario. The Company remains on schedule to
announce results of this bench-scale program and to produce lithium hydroxide (“LiOH”) samples for delivery
to prospective offtake partners in advance of PFS completion. The optimized flowsheet developed during this
testwork will serve as the basis of the Chemical plant prefeasibility study (“PFS”) to be completed in Q2 2020.
SGS is advancing a lithium conversion testwork program using a ‘direct-to-hydroxide’ approach developed in
collaboration with Piedmont Lithium personnel and engineering consultants Hatch and Primero Group.
Piedmont previously announced outstanding PFS-level metallurgical results for the production of spodumene
concentrate (see press release dated July 16, 2019). The concentrate produced during that program and other
spodumene concentrate produced from the same composite sample is now being used by SGS for the ongoing
bench-scale lithium hydroxide testwork.
Optimization tests on bench scale samples have been completed for calcination, roasting, water leach, primary
and secondary impurity removal, and filtration. Ion exchange tests have been completed. Work completed to
date represents approximately 90% of the steps in the bench scale testwork program, with multi-stage lithium
hydroxide crystallization and final assay results expected in coming weeks.
