Piedmont Lithium Partner Atlantic Lithium Confirms High-Grade Mineralization, Completing Drilling Program for Ghana Project

Plans advance for Atlantic Lithium's flagship Ewoyaa project in Ghana, which is expected to be a primary source of spodumene concentrate for Piedmont's Tennessee Lithium project

Piedmont Lithium ("Piedmont" or "Company") (Nasdaq:PLL; ASX:PLL), a leading global developer of lithium resources critical to the U.S. electric vehicle ("EV") supply chain, today announced that Atlantic Lithium (AIM:ALL; ASX:A11) has completed infill and exploration drilling for their flagship Ewoyaa project in Ghana. The assay results confirm high-grade mineralization, providing further confidence in resource conversion and possible mine life extension.

Piedmont is earning a 50% interest in Atlantic Lithium's spodumene projects in Ghana. This agreement includes an offtake agreement for 50% of annual production at market prices on a life-of-mine basis. Piedmont also owns a 9.4% equity interest in Atlantic Lithium.

Piedmont President and Chief Executive Officer Keith Phillips commented, "The drill results at Ewoyaa continue to be very impressive with high lithium grades over broad widths and near surface. We are working closely with our partners at Atlantic Lithium to publish a definitive feasibility study for the Ewoyaa project in the first half of 2023, and these final drill results are expected to lead to an extended mine life and even stronger economics for this world-class project. When fully operational, the Ewoyaa project will be a primary supplier of spodumene concentrate for lithium hydroxide conversion in Tennessee, and it is promising to see both projects progressing so favorably."

Cautionary Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred Resources and Proved and Probable Ore Reserves

The terms "mineral resource," "measured mineral resource," "indicated mineral resource," "inferred mineral resource," "ore reserves," "proved ore reserves" and "probable ore reserves" are terms defined by the U.S. Securities and Exchange Commission ("SEC") in Regulation S-K, Item 1300 ("S-K 1300") or the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the "JORC Code"). In Atlantic Lithium's announcement, it indicates that it has prepared resources information in accordance with the standards set forth in the 2012 Edition of the JORC Code. Such standards differ from the requirements of U.S. securities laws that would apply if Atlantic were a reporting company in the United States. Therefore, the mineral resources and ore reserves reported by Atlantic Lithium are not comparable to similar information made public by U.S. companies subject to reporting and disclosure requirements under the U.S. federal securities laws and the rules and regulations thereunder. U.S. investors are urged to consider closely the context and nature of Atlantic Lithium's disclosures in its public communications, as well as the disclosure in Piedmont's Form 10-KT, a copy of which may be obtained from Piedmont or from the EDGAR system on the SEC's website at http://www.sec.gov/.
