Piedmont Completes Additional Testwork to Produce High Grade Spodumene and Byproduct Concentrates

(firmenpresse) - - 120 kg of Dense Medium Separation (DMS) and flotation concentrates prepared for LiOH testwork
- Byproduct quartz samples have received positive initial feedback from key potential customers
o Quartz samples meet solar glass customer specifications - additional samples requested
o Additional potential clients will receive byproduct quartz, feldspar and mica samples in Q2
- Chemical plant Pre-Feasibility Study and updated integrated Scoping Study expected in May 2020
- Lithium hydroxide bench scale testwork nearing conclusion with results expected in Q2 2020

Piedmont Lithium Limited (Piedmont or Company) is pleased to announce that it has produced 120 kg of spodumene concentrate from core samples collected from the Companys Piedmont Lithium Project (Project) located within the world-class Carolina Tin-Spodumene Belt (TSB) . These samples have now been used in the bench-scale lithium hydroxide testwork program nearing completion at SGS laboratories in Lakefield, Ontario. Concentrate qualities and recoveries were consistent with earlier testwork programs.

We are also pleased to announce production of additional larger-scale samples of quartz and feldspar concentrates as part of this testwork. Quartz samples prepared in SGS laboratories were delivered to potential solar glass customers and met customer quality expectations.

Confidential customer discussions are ongoing through the Companys marketing partnership with Ion Carbon, a division of AMCI. Samples of quartz and feldspar concentrates will be delivered to other potential clients in the coming weeks. Mica samples will be produced in the coming weeks.

The updated spodumene concentrate and byproduct results will be used to support the Companys study updates which will be announced later this month.

Keith D. Phillips, President and Chief Executive Officer, commented: Our lithium hydroxide testwork program continues at SGS, and is based on the high-quality, low impurity spodumene concentrate prepared from a 1.75 tonne representative ore sample from Piedmonts Core property. Byproduct testwork is also continuing, and after positive initial customer feedback we have received from prospective quartz customers, we are beginning to evaluate the opportunity to expand our planned byproduct production, potentially further lowering our spodumene concentrate costs.

Bench-Scale Lithium Hydroxide Testwork Sample Preparation

To support lithium conversion testwork, Piedmont composited approximately 1.75 tonnes of pegmatite from drill core. This composite was collected from early, middle and late years of the deposit and resulted in a head grade of 1.25% Li2O and 0.38% Fe2O3. Spodumene concentrate was produced using the flowsheet in Figure 1.

The combined DMS concentrate was on-spec at >6.0% Li2O and <1.0% Fe2O3 and recovered just under 40% of the total lithium in the composite. Lithium losses to the DMS tailings were 8% (in 43% of the initial mass), with the remaining 53% of the lithium reporting to the flotation feed. The flotation feed was created by combining the middlings of the re-crush DMS operation with the combined -1 mm fraction. The lithium grade of the flotation feed (1.30% Li2O) was similar to the head grade of the composite.

A subsample of the flotation feed was stage-ground to 100% passing 300 µm and split into charges for batch and locked-cycle flotation testwork. The goal of these tests was to optimize the spodumene flotation flowsheet, test the impact of certain operating parameters and produce concentrate for conversion testwork.

Generally strong flotation performance was observed in the batch spodumene flotation tests. The key conclusions from the testwork were:

- Of the five spodumene collectors tested, the best spodumene flotation performance was achieved using a collector blend (FA-2 / TP-A100) in the developed flowsheet.
- The addition of a mica flotation stage prior to spodumene flotation was generally found to be favorable to the metallurgical response. This aspect of design will be further examined during the DFS.
- The use of site water in place of water sourced at SGS Lakefield showed improvement in flotation performance under the conditions tested.

Excellent results were obtained in a locked-cycle test (LCT) using the optimized spodumene flotation flowsheet developed during the batch flotation testwork. The LCT spodumene 2nd cleaner concentrate graded 6.13% Li2O and 0.83% Fe2O3, while recovering 82.1% of the lithium in the flotation feed.

Table 4 presents the metallurgical properties of the mathematically combined DMS + LCT spodumene concentrate, which provide a projection of the expected metallurgical performance of the developed DMS + flotation process flowsheet. As a result of strong lithium beneficiation performance in both DMS and flotation processes, the combined concentrate met the project targets with >6% Li2O and <1% Fe2O3 grade and lithium recovery in excess of >80% (based on the lithium in the composite feed).

Overall, the testwork program produced 122 kg of spodumene concentrate including 105 kg of DMS product and 17 kg of flotation product. This concentrate is now being progressed through a lithium hydroxide testwork program at SGS labs with results expected in June 2020.

Site Water Flotation Tests

Bench scale tests were performed to investigate and optimize collector selection, including tests undertaken with groundwater samples collected at Piedmont and shipped to SGS. Bench-scale tests including mica pre-flotation using a collector blend (FA/2-TPA 100) with process water collected from the Piedmont site provided the best performance.

Byproduct Metallurgy

The production of bulk quartz and feldspar concentrates as byproducts from the spodumene locked-cycle flotation tailings was investigated. Six (6) individual batch tests were conducted with the quartz and feldspar concentrates being composited. The flowsheet used for byproduct flotation is presented in Figure 3. The results of these tests are provided in Table 5.

Quartz concentrate results met prospective customer specifications provided to Piedmont by Ion Carbon, Piedmonts partner for marketing and sales of quartz, feldspar, and mica products. Samples sent to a confidential client were positively received. Larger follow up samples with optimized particle size distribution are planned.

Next Steps

The following next steps have been identified based on these results and dialog with byproduct customers including:

- Complete a trade-off study of mica pre-flotation to enhance spodumene concentrate grade and recovery during the definitive feasibility study.
- Investigate additional byproduct potential via reprocessing of DMS float product for additional quartz and feldspar potential.
- Produce optimized particle size distribution samples of quartz concentrate to confidential key client accounts.

North Arrow conducted surface

drilling programs for a total of
19 holes. Piedmont Lithium, Inc.
