Important Information and Disclaimer ELEVRA LITHIUM 12 Cautionary Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred Mineral Resources Standard for Assessing Mineral Reserves and Resources As a public company listed in Australia and the United States, Sayona Mining is required to comply with the resource estimation standards of both the JORC Code and S-K 1300. Certain of Sayona’s disclosures instead comply with the JORC Code or Canadian National Instrument 43-101, Standards of Disclosure for Mineral Projects (“NI 43-101”). Each of these standards contain specific meanings for terms such as “mineral resource”, “measured mineral resource”, “indicated mineral resource”, “inferred mineral resource”, “proven mineral reserves”, and “probable mineral reserves” for various types of technical studies. Although the principles for reporting mineral resources and reserves, including subcategories of measured, indicated, and inferred resources, are broadly similar under each set of standards, we caution you that estimates prepared solely under the JORC Code are not fully comparable to similarly titled measures disclosed under S-K 1300 or the other reporting and disclosure requirements of the U.S. federal securities laws, rules and regulations. Mineral Reserves and Resources of the Carolina Lithium Project Mineral reserve and mineral resource information contained in this presentation for the Carolina Lithium Project was prepared by Piedmont in accordance with S-K 1300 and the JORC Code. Mineral Reserves and Resources of the North American Lithium, Authier, and Moblan Projects Mineral reserve and mineral resource information contained in this presentation for the North American Lithium, Authier, and Moblan Projects were prepared in accordance with the JORC Code and NI 43-101. Such information was not prepared in accordance with S-K 1300.
