Piedmont Lithium Partner Sayona Mining Doubles Quebec Lithium Resource Estimate

Piedmont Lithium Inc. (“Piedmont” or the “Company”) (NASDAQ: PLL; ASX: PLL), a leading, diversified developer of lithium resources required to enable the U.S. electric vehicle supply chain, today announced that Piedmont’s partner, Sayona Mining (ASX:SYA), recently announced completion of a Mineral Resource estimate update for the North American Lithium and Authier Projects in Quebec totaling 119.1 million metric tonnes @ 1.05% Li₂O. Piedmont owns a 25% project interest in the North American Lithium and Authier Projects via an equity stake in Sayona Quebec as well as an equity interest of approximately 17% in Sayona Mining. Sayona Mining’s estimate, including 73.7 Mt @ 1.05% Li₂O of Measured and Indicated Resources, was reported in accordance with JORC Code (2012) and NI 43-101 standards.

“Sayona’s reported doubling of the Mineral Resources at North American Lithium and Authier supports Sayona Quebec’s claim as the largest spodumene resource in Canada, and this is the next step in helping Piedmont achieve its vision of becoming the leading lithium hydroxide producer in North America,” said Piedmont COO, Patrick Brindle. Mr. Brindle added, “We are happy and excited for our partners. Sayona Quebec is one of the largest and best-located spodumene businesses in Canada and, as a past-producer with the bulk of plant and equipment in place, we believe is also the most advanced at this time. We look forward to Sayona’s upcoming release of new technical studies for both Authier and North American Lithium as we advance our plans to jointly restart spodumene concentrate production at North American Lithium in 2023 as the world’s demand for electric vehicles and lithium hydroxide continues to accelerate.”

The statements below were prepared by, and made by, Sayona. The following disclosures are not statements of Piedmont and have not been independently verified by Piedmont. Sayona is 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 Resources

The terms "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" are terms defined by the U.S. Securities and Exchange Commission (“SEC”) in Regulation S-K, Item 1300 (“S-K 1300”) as well as the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the “JORC Code”) and the Canada Securities Administrators National Instrument 43-101 Standards for Disclosure for Mineral Projects (“NI 43-101”). In Sayona’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 and NI 43-101. Such standards differ from the requirements of U.S. securities laws that would apply if Sayona were a reporting company in the United States. Therefore, the mineral resources reported by Sayona Mining 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 Sayona’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/.
