NEW YORK – Piedmont Lithium Limited (“Piedmont” or “Company“) is pleased to announce that it has entered into agreements (“Agreements”) to establish a strategic partnership with Sayona Mining Limited (“Sayona”) (ASX:SYA) through the purchase of equity stakes in Sayona and its 100% owned Quebec subsidiary, Sayona Quebec Inc (“Sayona Quebec”), as well as a binding supply agreement for at least 50% of Sayona Quebec’s planned spodumene concentrate production.

Piedmont will acquire an initial 9.9% equity interest in Sayona for approximately US$3.1 million (“Share Placement“) and two unsecured convertible notes (“Convertible Notes“) for approximately US$3.9 million that upon conversion would result in Piedmont acquiring an additional 10.0% equity interest in Sayona. Piedmont will appoint one director to Sayona’s Board of Directors. Piedmont will also purchase a 25.0% stake in Sayona Quebec for approximately US$5.0 million in cash (“Project Investment“). Sayona Quebec owns the DFS-level Authier lithium project, the highly prospective Tansim lithium project, and is pursuing a bid to acquire Quebec-based North American Lithium’s (“NAL“) assets.

Piedmont and Sayona Quebec have also entered into a binding spodumene concentrate (“SC6“) supply agreement (“Supply Agreement“) pursuant to which Sayona Quebec will supply to Piedmont the greater of 60,000 t/y or 50% of Sayona Quebec’s SC6 production at market prices on a life-of-mine basis.

The Share Placement and issue of the Convertible Notes are expected to close the week of January 11, 2021 with the Project Investment expected to close in February 2021. Material terms of the Agreements are included in the Summary of Transaction Terms at the end of this announcement.

Keith D. Phillips, President and Chief Executive Officer, commented: “Piedmont’s partnership with Sayona will provide multiple benefits. Sayona has high quality asset in a favorable location, and the investments are being made at an attractive valuation. The investments are additive to Piedmont from a resources and reserves perspective, and the spodumene supply agreement will offset our Tesla commitments in the near term and position us for longer term growth in lithium hydroxide production. Furthermore, Sayona’s pursuit of the brownfield assets of NAL offers a unique regional consolidation opportunity.

“Quebec is poised to become an important lithium hydroxide production center given its abundant mineral resources, low-cost, sustainable hydro-electric power, proximity to major US and European electric vehicle markets, and pro-electrification stance of provincial leaders. Sayona’s assets are favorably located in the Val-d’Or region of central Quebec, home to major mining concerns and proximate to first-class infrastructure. Sayona’s core Authier project is well-advanced, with reserves declared and DFS complete, the nearby Tansim project offers strong exploration potential, and the regional consolidation opportunities including NAL are intriguing.”

“This is a very exciting step for Piedmont. We look forward to supporting Sayona’s team as they drive day-to-day activities in Quebec, while Piedmont’s team focuses on its core interests in North Carolina. 2021 will be an important year for our Piedmont Lithium Project, as we plan to expand our mineral resources, finalize permitting, execute additional lithium offtake agreements, complete an integrated definitive feasibility study, and secure strategic project financing. We are fortunate to have a strong balance sheet to comfortably fund the Sayona investments without compromising our aggressive plans in North Carolina.”

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

The Project’s Core property Mineral Resource of 25.1Mt @ 1.13% Li₂O comprises Indicated Mineral Resources of 12.5Mt @ 1.13% Li₂O and Inferred Mineral Resources of 12.6Mt @ 1.04% Li₂O. The Central property Mineral Resource of 2.80Mt @ 1.34% Li₂O comprises Indicated Mineral Resources of 1.41Mt @ 1.38% Li₂O and 1.39Mt @ 1.29% Li₂O. The information contained in this announcement has been prepared in accordance with the requirements of the securities laws in effect in Australia, which differ from the requirements of U.S. securities laws. The terms “mineral resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” are Australian terms defined in accordance with the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the “JORC Code”). However, these terms are not defined in Industry Guide 7 (“SEC Industry Guide 7”) under the U.S. Securities Act of 1933, as amended (the “U.S. Securities Act”), and are normally not permitted to be used in reports and filings with the U.S. Securities and Exchange Commission (“SEC”). Effective January 1, 2021, the SEC has adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the Exchange Act and as a result, the SEC now recognizes estimates of “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources”. In addition, the SEC has amended its definitions of “proven mineral reserves” and “probable mineral reserves” to be “substantially similar” to the corresponding definitions under the JORC Code. However, information contained herein that describes Piedmont’s mineral deposits may not be 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 disclosure in Piedmont’s Form 20-F, a copy of which may be obtained from Piedmont or from the EDGAR system on the SEC’s website at http://www.sec.gov/.
