Piedmont Lithium Partners Release Technical Studies

 Atlantic Lithium releases DFS for Ewoyaa Lithium Project

Sayona Mining publishes preliminary technical study for carbonate production at NAL

Piedmont Lithium (the “Company,” “Piedmont,” “we”, “our” and “us”) (Nasdaq: PLL; ASX: PLL), a developer of lithium resources critical to the U.S. electric vehicle supply chain, today announced that partners Atlantic Lithium (AIM: ALL; ASX: A11) and Sayona Mining (ASX: SYA) have released technical studies on the Ewoyaa Lithium Project (“Ewoyaa”) in Ghana and the producing North American Lithium project (“NAL”) in Quebec, respectively.

Atlantic Lithium Limited (“Atlantic Lithium”) recently published a JORC Code-compliant definitive feasibility study (“DFS”) for Ewoyaa. When implementing a mine plan developed on the basis of 25.6 million metric tons at 1.22% Li₂O of probable ore reserves only and excluding any mineral resources in the inferred category, the DFS delivers a production target of 340,000 metric tons per year of spodumene concentrate, half of which is expected to be delivered to Piedmont Lithium under the Company’s 50% allocation of production from Atlantic Lithium’s Ghanaian projects. The DFS projected robust economics for Ewoyaa, demonstrating an estimated after-tax net present value of US$1.4 billion and an after-tax internal rate of return of more than 100%. Piedmont Lithium is in the process of earning a 50% ownership interest in Ewoyaa. Based on completion of the DFS and Piedmont Lithium’s election to proceed into project development, the Company expects to earn the first 22.5% ownership interest in Ewoyaa. Atlantic Lithium is progressing through the mine permitting process, targeting construction at Ewoyaa to commence in the second half of 2024, with first production expected in 2025.

Sayona Mining Limited (“Sayona Mining”) released a preliminary technical study for lithium carbonate production at the operating NAL mine. NAL is jointly owned by Sayona Mining (75%) and Piedmont Lithium (25%). The NAL site includes a lithium carbonate facility that was partially completed by prior owners of the operation. Sayona Mining and Piedmont Lithium plan to work together with technical advisors to perform a trade-off study of lithium carbonate versus lithium hydroxide production at NAL, with a definitive technical study to follow for publication sometime in 2024. Spodumene concentrate operations at NAL have been ramping up since first production in March 2023, and first commercial shipments to customers are expected in Q3 2023.

Keith Phillips, President and CEO of Piedmont Lithium, commented, “We are grateful for the outstanding work by our partners at Atlantic Lithium and Sayona Mining in advancing these projects. We expect Ewoyaa to provide the primary feedstock for Tennessee Lithium and are in the final stages of securing the material permits needed to construct and operate the conversion facility. We look forward to the first spodumene shipments from NAL, expected in Q3 2023, and to confirming Piedmont’s transition from lithium developer to lithium producer.”

Atlantic Lithium and Sayona Mining are not subject to U.S. reporting requirements or obligations, and investors are cautioned not to put undue reliance on these statements.

Cautionary Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred Mineral Resources

Information presented herein related to the mineral resources and mineral reserves of Ewoyaa have been prepared in accordance with the requirements of the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources, and Ore Reserves (the “JORC Code”). Comparable terms are now also defined by the SEC in its newly adopted Modernization of Property Disclosures for Mining Registrants as promogulated in its S-K 1300 standards. While the guidelines for reporting mineral resources, including subcategories of measured, indicated, and inferred mineral resources, are largely similar for JORC and S-K 1300 standards, information contained herein that describes Atlantic Lithium’s mineral deposits are not fully 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 Piedmont’s disclosure in its SEC filings, copies of which may be obtained from Piedmont or from the EDGAR system on the SEC’s website at www.sec.gov.​

In June 2023, Atlantic Lithium announced the successful completion of a definitive feasibility study for Ewoyaa in accordance with the JORC Code, demonstrating the potential of Ewoyaa to produce low-cost spodumene concentrate using a dense medium only processing technique. In the Atlantic Lithium definitive feasibility study, 6% of the mined tons in the production target are based on the inclusion of inferred resources. Piedmont has disclosed the production target and estimated project economics of Ewoyaa on the basis of mining and processing of probable ore reserves only according to information provided by Atlantic Lithium in [Table 1 Section 4][[“‘JORC Code 2012 Table 1’ Section 4 Estimation and Reporting of Ore Reserves”?] of Atlantic’s DFS announcement released to the ASX on June 29, 2023. We consider the production target and its associated economics as a definitive feasibility study on the basis of processing ore reserves only.

Investors are cautioned that there is a low level of geological confidence associated with inferred mineral resources, and there is no certainty that further exploration work would result in a determination of measured or indicated mineral resources resulting from the inferred resources, that the inferred resources would be converted to mineral reserves or that the production target itself would be realized.
