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

Piedmont Lithium Limited (ASX:PLL; NASDAQ:PLL) (“Piedmont” or “Company”) is pleased to announce that it has produced 120 kg of spodumene concentrate from core samples collected from the Company’s 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 Company’s 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 Company’s 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 Piedmont’s 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.
