Business Wire
- Bench-scale lithium hydroxide testwork has been successfully
completed at SGS Canada
- Testwork results compare favorably with current battery
quality market specifications
Piedmont Lithium Limited (“Piedmont” or “Company”)
is pleased to announce that it has completed a bench-scale testwork
program at SGS Canada, Inc. (“SGS”) in Lakefield, Ontario to
produce initial quantities of battery-quality lithium hydroxide
monohydrate. Lithium hydroxide was produced from spodumene
concentrate produced at SGS from core samples taken from the
Piedmont Lithium Project (“Project”). Quality results compare
favorably with current market specifications for battery quality
lithium hydroxide. Testwork results are shown in Table 1.

The program results demonstrate the ability of Piedmont to
concentrate and produce battery-quality lithium hydroxide via an
‘ore-to-hydroxide’ conversion route which is consistent with the
chemical plant process design in the Company’s recently completed
lithium chemical plant prefeasibility study.
Keith D. Phillips, President and Chief Executive Officer,
commented: “The successful production of battery quality lithium
hydroxide from ore samples taken from the Company’s drill core
represents a major milestone for Piedmont Lithium. The Carolina
Tin-Spodumene Belt is renowned for its pure spodumene mineralogy,
and we are very pleased that this testwork program confirms the
low-impurity profile of our 100%-owned mineral resource. With
Austin Devaney now on board as our VP - Sales & Marketing, we
look forward to sharing these results with prospective customers in
the automotive, battery and cathode businesses, as we advance in
our goal of becoming a leading American lithium hydroxide
producer.”
