Piedmont Lithium Announces Outstanding PFS-level Metallurgical Results

Piedmont Lithium Announces Outstanding PFS-level Metallurgical Results

ID: 595935

(firmenpresse) - - Testwork confirms ability to produce high-grade, low impurity spodumene concentrate
- Flow sheet adjusted to incorporate a combination of DMS and flotation processing
- Process simulations based on testwork results support a design basis of 85% lithium recovery
- Mineralogy shows spodumene as the only lithium bearing mineral in concentrate
- Optimization to further improve recoveries will be undertaken during Definitive Feasibility Study
- Updated flow sheet will be reflected in a Scoping Study update expected in the next 30 days

Piedmont Lithium Limited (Piedmont or Company) is pleased to announce positive results from pre-feasibility study (PFS) level metallurgical test work conducted on composite samples of ore from the Piedmont Lithium Project (Project) performed at SGS testing laboratories in Lakefield, Ontario.

Dense Medium Separation (DMS) and flotation Locked-Cycle Tests (LCT) test work results showed high quality spodumene concentrate product with a grade above 6.0% Li2O, iron oxide below 1.0%, and low impurities from composite samples. Piedmont test results compare favorably in several quality categories with the reported shipments of three emerging Australian spodumene producers.

The composite samples were prepared to approximate the average grade of the Projects ore body. Overall lithium recovery during testwork for the preferred flowsheet was 77% at a grade of 6.35% Li2O. Simulations based on the testwork results support an overall plant design recovery of 85% when targeting a 6.0% Li2O spodumene concentrate product. Further optimization will be undertaken in a future feasibility level pilot testwork program.

The Companys forthcoming Scoping Study update will incorporate the updated flow sheet developed during this test work program. The benefit of incorporating DMS technology into the flow sheet will be reduced operating costs and accelerated ramp-up.

Keith D. Phillips, President and Chief Executive Officer, commented: We are very pleased with the results of this PFS-level testwork program, which confirms the outstanding mineralogy and metallurgy of the Piedmont Lithium Project. We look forward to reflecting these strong results in our forthcoming Scoping Study update, which will also incorporate the substantially larger mineral resource announced in June as well as several other constructive refinements.

Following on from the success of the Companys 2018 bench-scale metallurgical test work which demonstrated spodumene concentrate grades of >6.0% Li2O with low iron content of <1% Fe2O3, the Company has now completed the next phase of metallurgical test work, comprising composite samples from the Projects ore body, which has confirmed and expanded upon the prior test work.

This next phase metallurgical test work included evaluation of DMS technologys potential to function as a concentration step to produce high-quality spodumene concentrate. Flotation LCT test work was also performed on the composite samples to verify prior test work and estimate spodumene recoveries.

Samples weighing 160 kg to 220 kg were composited from mineralized core samples drilled within the Companys Core Property. Dilution material was added to each of the composites to create samples which would be representative of future operations.

Samples were processed in SGS Lakefields pilot DMS plant. Samples were processed as a coarse fraction (6.35mm x 3.3mm) and fine fraction (3.3mm x 1.0mm) and subjected to two stages of separation. Ultrafine material (1.0mm x 0) was screened from each sample for flotation locked-cycle tests. DMS tests were able to reject between 27.8% to 33.8% mass with lithium losses between 2.7% to 4.4%.

Middlings from DMS was re-crushed to -3.3mm and reprocessed. Fine materials (-1.0mm) generated during re-crushing were added to the ultrafine material and processed by locked cycle flotation. Middlings regrinding and reprocessing in flotation enable Piedmont to maintain high overall spodumene recoveries.

The PFS-level DMS testwork program used variable techniques for magnetic separation and mica removal between composite samples. These variations in testwork will enable Piedmont to conclude a PFS level flowsheet design by the end of July. The preferred process flow diagram and results are reported.

Figure 1 shows photographs of the coarse and fine DMS concentrates produced using the preferred process flow diagram. Piedmont spodumene concentrate is generally light green to white colored.

Ultrafine material and DMS middlings were ground to 300 microns. Prior to locked cycle flotation the flotation feed material was subjected to two stages of desliming and about 10 minutes of high density attrition scrubbing.

Seven cycles of locked cycle flotation testwork including spodumene rougher flotation and three cleaner stages was performed on variability samples with the average results of cycles 3-7 reported. 3rd cleaner spodumene concentrate was subjected to magnetic separation with the non-magnetics reported as final concentrate.

Based on the results of composite DMS and locked cycle flotation testwork the preferred process flow block diagram for the Project is shown in Figure 2.

Explora> Acknowledgment The Project is focused over an
tion and appraisal of area that has been explored for
done exploration by lithium dating back to the 1950s
by other where it was originally explored
other parties. by Lithium Corporation of America
partie which was subsequently acquired
s by FMC Corporation. Most
recently, North Arrow explored
the Project in 2009 and 2010.
North Arrow conducted surface
sampling, field mapping, a ground
magnetic survey and two diamond
drilling programs for a total of
19 holes. Piedmont Lithium, Inc.
has obtained North Arrows
exploration
data.

Cherryville granite, as the dikes
progressed further from their
sources, they became increasingly
enriched in incompatible elements
such as Li, tin (Sn). The dikes
are considered to be

unzoned.
