Piedmont Commences Next Phase of Metallurgical Testwork

 
PRESS RELEASE  |  March 5, 2019  |  NASDAQ:PLL  |  ASX:PLL
  • PFS-level metallurgical testwork program has commenced at SGS
    Lakefield
  • Testwork will evaluate Dense Medium Separation, flowsheet
    optimization and ore variability
  • Program builds on 2018 results demonstrating low-iron concentrate
    grades of 6.0-6.5% Li
    2O
  • Appointed a number of consultants and suppliers to support
    additional studies in 2019

NEW YORK – Piedmont Lithium Limited (“Piedmont” or “Company”) has commenced
a PFS-level metallurgical testwork program at SGS Canada’s facilities in
Lakefield, Ontario. The testwork will be completed using composite and
variability samples collected from drill cores produced during the
Company’s Phase 2 and Phase 3 drill campaigns.

The planned testwork program builds on the success of the Company’s 2018
bench-scale testwork which previously demonstrated spodumene concentrate
grades of 6.0-6.5%
Li2O with low iron content of
0.66-0.76%
Fe2O3.

New tests will include evaluation of Dense Medium Separation (DMS)
technology’s potential to function as a pre-concentration step to
production of high-quality spodumene concentrate. Locked-cycle flotation
tests will also be performed on composite and variable samples to verify
prior testwork and estimate spodumene recoveries.

The results of the testwork program will be used to further optimize the
process flow diagram during the next phases of technical study of the
Company’s planned spodumene concentrator. Test results will also be used
to design a pilot testwork program planned for the second half of 2019.
Additional by-product testing is also planned in the second half of 2019.

Piedmont is also pleased to announce the appointment of engineers and
consultants supporting the Company in areas of environmental study,
permitting, metallurgy, mining engineering, exploration, and land
acquisition as the project team focuses on a construction decision by
the end of 2019.

Our full announcement and our complete list of consultants can be seen here.

Keith D. Phillips, President and Chief Executive Officer, said, “We
are pleased to be working with SGS Lakefield on the next phase of our
metallurgical testing.
SGS is a global leader with extensive
experience in the field of spodumene concentrate testwork.
We are
also pleased to announce the appointments of several additional
consultants experienced in areas critical to our success.
Our
Phase 4 drill campaign is going very well, and we look forward to
reflecting this in important engineering studies over the course of
2019.”
