Piedmont Achieves Milestone with Production of Battery Quality Lithium Hydroxide
(firmenpresse) - - 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 Companys 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 Companys 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.

Bench-Scale Lithium Hydroxide Testwork Program
To support lithium conversion testwork Piedmont prepared a spodumene concentrate sample using dense medium and flotation processing. The results of the concentrate sample preparation were previously reported on May 13, 2020. Refer to Company announcement Piedmont Completes Additional Testwork to Produce High Grade Spodumene and Byproduct Concentrates. A testwork program was designed to run small-scale optimization tests and bulk tests to carry the concentrate sample through to battery quality lithium hydroxide. Figure 1 describes the overall testwork plan.

The bench-scale lithium hydroxide testwork program was a multi-step effort that includes extraction of lithium from spodumene, several stages of impurity removal, and a sequence of crystallization steps. A summary of the steps involved is outlined in this announcement.

About Piedmont Lithium
Piedmont Lithium Limited (ASX: PLL; Nasdaq: PLL) holds a 100% interest in the Piedmont Lithium Project, a pre-production business targeting the manufacturing of 22,700 t/y of battery quality lithium hydroxide in North Carolina, USA to support electric vehicle and battery supply chains in the United States and globally. Piedmonts premier southeastern USA location is advantaged by favorable geology, proven metallurgy and easy access to infrastructure, power, R&D centers for lithium and battery storage, major high-tech population centers and downstream lithium processing facilities. Piedmont has reported 27.9Mt of Mineral Resources grading at 1.11% Li2O located within the world-class Carolina Tin-Spodumene Belt (TSB) and along trend to the Hallman Beam and Kings Mountain mines, which historically provided most of the western worlds lithium between the 1950s and the 1980s. The TSB has been described as one of the largest lithium provinces in the world and is located approximately 25 miles west of Charlotte, North Carolina.
