NEW YORK – Piedmont Lithium Limited (“Piedmont” or the “Company”) (Nasdaq:PLL; ASX:PLL) is pleased to announce an updated Global Mineral Resource estimate (“MRE”) (Table 1) for the Company’s flagship Piedmont Lithium Project in North Carolina, USA which includes updated Mineral Resource estimates from the Core and Central properties and an initial Mineral Resource estimate from the Huffstetler property (Table 2). The total MRE for the project is 39.2 Mt at 1.09% Li₂O (Figure 1), with 55% of the MRE currently classified in the Indicated category. The Mineral Resource estimate is reported in accordance with JORC Code (2012 Edition).

Keith D. Phillips, President and Chief Executive Officer, commented: “Increasing the scale of our North Carolina mineral resource to 39.2 Mt at 1.09% Li₂O establishes our asset as one of the largest spodumene resources in North America – and the only one in the United States. The expanded resource offers the potential for increased annual lithium production, something we will evaluate as we prepare our updated Scoping Study for release next month. All this is coming together at an ideal time, as the public and private sectors dramatically increase their investment in the electrification of America. Given the scope and strategic location of our Piedmont Lithium Project, we believe we are ideally positioned to play a critical role in helping the United States build a clean energy economy and a U.S. based EV supply chain.”
