Inaugural Mineral Resources reported under new U.S. S-K 1300 Standards
- Carolina Lithium Project total Mineral Resources increase to 44.2 Mt @ 1.08% Li2O
- Indicated Mineral Resources increased 101% to 28.2 Mt @ 1.11% Li2O for the Project
- DFS completion for the integrated 30,000 t/y LiOH Carolina Lithium Project expected within Q4 2021
BELMONT, NC – Piedmont Lithium Inc. (Nasdaq: PLL) (“Piedmont” or “Company”) is pleased to announce an updated global Mineral Resource estimate (“MRE”) (Table 1) for the Company’s flagship Carolina Lithium Project in North Carolina, USA. The MRE includes updates for lithium and industrial mineral products. The total MRE for the project is 44.2 Mt @ 1.08% Li2O, with 64% of the total MRE classified in the Indicated category. The Mineral Resource estimate reported in accordance with the U.S. Securities and Exchange Commission S-K 1300 standards and the Australasian JORC Code (2012 Edition).

Keith D. Phillips, President and Chief Executive Officer, commented: “We are very pleased to have concluded our Phase 5 drill campaign and to further expand our world-class resource base. Carolina Lithium has one of the largest spodumene resources in North America, and the only one located in the United States. The increase in ‘Indicated’ resources of over 100% relative to resources previously reported under Australian standards, will underpin the definitive feasibility study for Carolina Lithium that we plan to publish later in 2021. The DFS will be another important step along the path to building America’s leading lithium business to support and enable the rapidly-growing electric vehicle supply chain in the United States.”
The Company intends to file an inaugural Technical Report Summary in accordance with the United States Securities and Exchange Commission Regulation S-K 1300 Modernization of Property Disclosures requirements in the Company’s next Quarterly Report on Form 10-Q.
The updated Mineral Resources will be incorporated into the upcoming Definitive Feasibility Study of the Carolina Lithium Project, which the Company expects to complete within Q4 2021.

Technical Discussion
Overview
Piedmont holds a 100% interest in the Carolina Lithium Project located within the Tin-Spodumene Belt and along trend to the Hallman Beam and Kings Mountain mines, which historically provided most of the western world’s lithium between the 1950s and the 1980s.
The Project is located in a rural area of Gaston County, North Carolina, USA approximately 40 km northwest of the city of Charlotte. The Project is located on the Bessemer City, Lincolnton West, and Lincolnton East United States Geological Survey (USGS) Quadrangles. The coordinate system and datum for the modeling is UTM-17N, NAD-83. The Property is centered at approximately 35°23’20”N 81°17”20”W and is comprised of approximately 3,245 total acres, of which 1,526 acres are claims on private property through option or deferred purchase agreements, 113 acres are under a long-term mineral leased agreement, 79 acres are under lease to own agreements, and 1,527 acres are owned by Piedmont. For the properties hosting the MREs in this report, Piedmont controls 100% of the surface and mineral rights per one or more agreement scenarios.
Future Exploration
Piedmont plans to release a Definitive Feasibility Study for the project within Q4 2021. Piedmont continues to evaluate newly acquired properties within the Carolina Tin Spodumene Belt for lithium mineralization.
The Qualified Person recommends the following actions are completed to support the ongoing Mineral Resource development effort at the Carolina Lithium Project:
- Investigate shallow portions of Core Property deposits deemed amenable to early-stage mining through infill drilling and appropriate surface methods, at 20 m to 40 m spacings. An understanding of the short-range variability of mineralization, pegmatite dike orientation, and weathering should be developed, and Measured resource classification criteria established.
- Model the extent of major metavolcanic and metasedimentary host rock units to support mine planning at the Core property. Models will improve bulk density estimation and support environmental and geotechnical characterization of waste rock.
- Conduct infill drilling to increase data density and support the upgrading of Mineral Resources from Inferred to Indicated throughout the Project.
- Undertake a study to identify new exploration targets and prioritize step-out drill targets that expand defined resource pegmatites.
- To support exploration targeting across its properties, and to direct future property acquisitions, Piedmont should continue to synthesize a mineral system model for spodumene bearing pegmatites along the TSB.
