About Piedmont Lithium

Piedmont Lithium Inc. (Piedmont Lithium), a development stage company, engages in advancing a multi-asset, integrated lithium business in the support of a clean energy economy and the United States (U.S. or America) and global energy security. The company plans to supply lithium hydroxide to the electric vehicle and battery manufacturing supply chains in North America by processing spodumene concentrate produced from assets the company owns or in which the company has an economic interest. The company’s portfolio of projects includes its proposed Tennessee Lithium Project and the company’s proposed, fully-integrated Carolina Lithium Project, which are under development in the southeastern U.S., and the company’s strategic investments in lithium assets in Quebec, Canada and Ghana, West Africa. The company expects spodumene concentrate production to come online in Quebec in the first half of 2023 and first commercial shipments are anticipated in the third quarter of 2023. Subject to obtaining permits, approvals, and financing, the company plans to obtain spodumene concentrate through the company’s offtake agreement in Ghana beginning in late 2024 or 2025, produce lithium hydroxide in Tennessee beginning in 2025 or 2026, and to produce spodumene concentrate and lithium hydroxide in North Carolina beginning in 2026 or 2027. Strategy The company’s plan is to produce battery-grade lithium hydroxide from spodumene concentrate. The company plans, as part of the company’s sustainability goals within the company’s overall environmental, social and governance (ESG) strategy, to develop the company’s greenfield operations in Tennessee and North Carolina as two of the most sustainable lithium hydroxide production operations in the world. The company’s portfolio of projects and strategic equity investments are being developed on a measured timeline to provide the potential for both near-term cash flow and long-term value maximization. At production, the company expects to have an estimated lithium hydroxide manufacturing capacity of 60,000 metric tons per year, as compared to the current total estimated U.S. lithium hydroxide production capacity of 15,000 metric tons per year. In the support of the company’s strategy, it continues to evaluate opportunities to further expand the company’s resource base and production capacity. Developing an Integrated Lithium Production Business—Key Projects Quebec Piedmont Lithium owns an equity interest of 25% in Sayona Quebec Inc. (‘Sayona Quebec’), which owns full interests in North American Lithium (‘NAL’), the Authier Lithium Project, and the Tansim Lithium Project. These projects are located in the Abitibi region of Quebec, Canada. Additionally, the company owns an equity interest of approximately 14% in Sayona Mining Limited (‘Sayona Mining’), which in turn owns 75% of Sayona Quebec. The company also holds an offtake agreement with Sayona Quebec for the greater of 113,000 metric tons per year or 50% of spodumene concentrate production at market prices. The company has entered into offtake agreements with two customers to provide them with spodumene concentrate from NAL. In addition to spodumene mining and concentrate production, NAL’s complex includes a partially completed lithium carbonate facility, which was developed by a prior operator of NAL. In the event Piedmont Lithium and Sayona Mining decide to jointly construct and operate a lithium conversion plant through their jointly-owned entity, Sayona Quebec, then spodumene concentrate produced from NAL would be preferentially delivered to that conversion plant upon commencement of conversion operations. Any remaining spodumene concentrate not delivered to a jointly-owned conversion plant would first be delivered to Piedmont Lithium up to the company’s offtake right and then to third parties. Sayona Quebec previously announced the commencement of a prefeasibility study for the completion NAL’s lithium carbonate facility. Study results are expected in the first half of 2023. Further evaluation of the production of lithium carbonate or lithium hydroxide in Quebec may follow completion of the prefeasibility study. For Sayona Quebec to proceed with the construction and operation of a lithium carbonate conversion plant or lithium hydroxide conversion plant, approvals are required from both Piedmont Lithium and Sayona Mining. Ghana The company owns an equity interest of approximately 9% in Atlantic Lithium Limited (‘Atlantic Lithium’) and has the ability to earn a 50% equity interest in Atlantic Lithium’s spodumene projects in Ghana, West Africa. This interest includes an offtake agreement for 50% of annual production of spodumene concentrate from the Ewoyaa Lithium project (‘Ewoyaa’), at market prices on a life-of-mine basis. Ewoyaa is Atlantic Lithium’s flagship project in the Cape Coast region of Ghana and located approximately 70 miles from a major port via a national highway. The company anticipates the development of the Ewoyaa project to be key for delivering spodumene concentrate to the company’s planned Tennessee Lithium plant for conversion to lithium hydroxide. In September 2022, Atlantic Lithium announced the successful completion of a prefeasibility study for Ewoyaa, demonstrating the potential of Ewoyaa to produce low-cost spodumene concentrate using a dense medium only processing technique. In October 2022, Atlantic Lithium announced it had submitted the mining lease application for Ewoyaa to the Minerals Commission of Ghana. Subject to the receipt of the mining lease, approval of environmental studies, and other statutory requirements, construction may begin at Ewoyaa between the end of 2023 and the first half of 2024 with first spodumene concentrate production between the end of 2024 and the first half of 2025. Tennessee Lithium The company’s proposed Tennessee Lithium project (‘Tennessee Lithium’) is expected to be a world-class lithium hydroxide production facility located within McMinn County near Etowah, Tennessee. With first production targeted by the end of 2025 or the first half of 2026, the facility is expected to produce 30,000 metric tons per year of lithium hydroxide, doubling the current estimated U.S. production capacity of 15,000 metric tons per year. The plant is expected to be one of the most sustainable lithium hydroxide operations in the world utilizing the innovative Metso:Outotec Pressure Leach Technology. Use of this technology is expected to reduce solid waste, create fewer emissions, lower carbon intensity, and improve capital and operating costs relative to incumbent technologies. In October 2022, Piedmont Lithium was selected for a grant from the U.S. Department of Energy (‘DOE’) to construct Tennessee Lithium. The grant is expected to support project development on a cost-sharing basis. Tennessee Lithium was included among the initial projects funded by the Bipartisan Infrastructure Law to expand domestic manufacturing of batteries for electric vehicles and the electrical grid and for materials and components currently imported from other countries. The grant will not be final until Piedmont Lithium and the DOE have agreed to specific terms and conditions of the grant. Once terms and conditions are finalized, funding of the grant will remain subject to satisfaction of conditions set forth in those terms. In August 2022, the company awarded a front-end engineering design (‘FEED’) contract to Kiewit Engineering Group Inc. (‘Kiewit’), a leading U.S. based engineer, procure, and construct (‘EPC’) firm. Kiewit is working with Primero USA Inc. (‘Primero’), an EPC firm specializing in lithium projects. The company expects FEED, which commenced shortly after the contract award, to be completed in the first half of 2023. Permit applications for Tennessee Lithium are progressing, and subject to receipt of all material required permits, completion of FEED, and project financing, the company expects to sign an EPC contract for the construction of Tennessee Lithium. Contingent upon the timely receipt and completion of items discussed above, the company expects to begin construction in 2023 or the first half of 2024 with first production of lithium hydroxide targeted by the end of 2025 or the first half of 2026. Carolina Lithium The company’s proposed, fully-integrated Carolina Lithium project (‘Carolina Lithium’) is a development stage, hard rock lithium project located within the Carolina Tin-Spodumene Belt of North Carolina and in close proximity to lithium markets. Carolina Lithium is expected to consist of a mining operation, concentrator, and lithium hydroxide conversion plant. In December 2021, the company completed a feasibility study. The project is expected to produce 30,000 metric tons of lithium hydroxide per year at full capacity. Due to the expected quality of this hard rock lithium asset, integration of the operation, existing infrastructure, and proximity to lithium and byproduct markets, Carolina Lithium will be one of the lowest cost lithium hydroxide manufacturing operations in the world. The company is engaged in permitting activities with state and local agencies for Carolina Lithium. In August 2021, the company submitted a mining permit application to the North Carolina Department of Environmental Quality’s (‘NCDEQ’) Division of Energy, Minerals, and Land Resources (‘DEMLR’). The company is in the process of responding to additional information requests made by DEMLR in connection with the company’s mining permit application, and the company has until May 2023 to respond. A Prevention of Significant Deterioration – Title V Air Permit application has been submitted to the NCDEQ Division of Air Quality and was deemed complete in February 2023. Marketing, Sales, and Principal Markets On July 31, 2020, the company entered into a strategic partnership with Ion Carbon & Mineral, LLC to form Pronto Minerals, LLC, for the purpose of marketing and selling byproducts, specifically quartz, feldspar, and mica, produced by the company’s proposed Carolina Lithium project. The company continues to explore potential strategic partnership and sales, offtake, and marketing agreements that will benefit the development of the company’s assets, as well as the U.S. electric vehicle supply chain. Customers On January 2, 2023, the company entered into an amended offtake agreement with Tesla, Inc. (‘Tesla’) to provide spodumene concentrate from NAL in Quebec. The agreement commits the company to sell 125,000 metric tons of spodumene concentrate from the company’s offtake agreement with Sayona Quebec. On February 16, 2023, the company entered into a spodumene concentrate offtake agreement with LG Chem. The agreement commits the company to sell 200,000 metric tons of spodumene concentrate from the company’s offtake agreement with Sayona Quebec. The term of the agreement expires four years from the date of first shipment, which is anticipated to occur by the third quarter of 2023, with the final shipment expected in the third quarter of 2027. Properties Tennessee Lithium Tennessee Lithium is expected to be a world-class lithium hydroxide production facility located within McMinn County in Etowah, Tennessee. With first production targeted by the end of 2025 or 2026, the facility is expected to produce 30,000 metric tons per year of lithium hydroxide, doubling the current estimated U.S. production capacity of 15,000 metric tons per year. The plant is expected to be one of the most sustainable lithium hydroxide operations in the world and among the first to use the innovative Metso:Outotec Pressure Leach Technology. As of December 31, 2022, the company did not own any property associated with Tennessee Lithium. Carolina Lithium Carolina Lithium is a development stage project for the mining, development and production of lithium products. The property is located in a rural area of Gaston County, North Carolina, approximately 25 miles northwest of the City of Charlotte. Spodumene Concentrate Operation The TRS for Carolina Lithium is based on a mine life of 11 years of mineral reserves, with an estimated average annual production of 242,000 metric tons of spodumene concentrate at steady-state. There is significant opportunity to increase the mineral reserve life of Carolina Lithium beyond 11 years by conversion of existing mineral resources to mineral reserves or by discovery of additional resources within the Carolina Tin-Spodumene Belt within a reasonable trucking or conveying distance to the proposed spodumene concentrator. Lithium Hydroxide Conversion Operation The TRS for Carolina Lithium assumes a lithium hydroxide conversion plant, also referred to as a chemical plant, that will be supported with spodumene concentrate produced from the company’s mineral reserves. The lithium hydroxide chemical plant has an estimated production rate of 30,000 metric tons of lithium hydroxide per year. The company’s business plan is, upon depletion of the company’s mineral reserves, to continue lithium hydroxide production at Carolina Lithium using spodumene concentrate sourced from offtake agreements, which will allow the company to secure spodumene concentrate from alternate sources or from the company’s own mineral reserves if the company’s estimation of mineral reserves was increased in the future. The company holds a 100% interest in Carolina Lithium, which is located approximately 25 miles north west of Charlotte, North Carolina in the U.S. As of December 31, 2022, Carolina Lithium was consisted of real property and associated mineral rights totaling approximately 3,245 acres, of which approximately 162 parcels consisting of 2,277 acres are owned; 1 parcel consisting of 113 acres is subject to long-term leases; 1 parcel consisting of 10 acres is subject to lease-to-own agreements; and 110 parcels consisting of 1,096 acres are subject to exclusive option agreements. The company generally controls all the surface and mineral rights for Carolina Lithium under applicable agreements. The company also owns real property totaling 5 acres in Bessemer City, North Carolina, where the company leases a warehouse for core samples from Carolina Lithium, and 61 acres in Kings Mountain, North Carolina, where the company holds a synthetic minor air permit and which was the subject of prior technical studies for a planned lithium hydroxide conversion facility.

Western Australia Properties The company has an equity interest of approximately 14% in Sayona Mining’s Western Australian exploration stage properties via the company’s equity stake in Sayona Mining as noted above. Sayona Mining owns a 100% economic interest in certain properties in Western Australia. Sayona Mining’s leases in Western Australia cover 264,895 acres and comprise lithium, gold and graphite tenure in the Pilbara, Yilgarn and East Kimberley regions. All of Sayona Mining’s Western Australia projects are in the exploration stage. The Pilbara projects comprise 12 lithium leases totaling 230,548 acres in the Pilgangoora lithium district of Western Australia, with 10 of the tenements also having associated gold rights. These are proximal to the De Grey Mining’s Mallina Gold project, which includes the Hemi gold discovery. Of the 12 Pilbara tenements with lithium rights, nine are subject to an earn-in agreement, whereby Morella Corporation Limited (‘Morella’), listed on the Australian stock exchange and previously known as Altura Mining, is carrying out exploration to earn an equity interest. The three remaining tenements are held within Sayona Mining’s wholly-owned lithium exploration portfolio. Pilbara Lithium Tenements In 2021, Morella commenced an earn-in agreement with Sayona Mining covering eight tenements, including the Mallina, Tabba East, and Strelley areas, all in the Pilgangoora lithium district, and two tenements in the South Murchison. Mallina Project (E47/2983)—The Mallina Project is the most advanced of Sayona Mining’s Pilbara portfolio. Multiple zones of spodumene pegmatites have been identified within a 6,178 acre zone. The pegmatites occur in three main swarms: the western Discovery prospect, the central Area C prospect and the Eastern Group pegmatites. Mapping has confirmed the pegmatites can be extensive, with the Eastern No.2 pegmatite being over 4,265 feet in strike extent and up to 66 feet in thickness. During Sayona Mining’s fiscal year ended June 30, 2022, Morella reported significant progress at the Mallina Project with the completion of a targeted deep drilling program. In total, three reverse circulation (‘RC’) holes for 1,411 feet and four diamond core holes, including two core tail extensions to RC drilling, were completed for 2,728 feet. Fine grained spodumene quartz intergrowths within aplite intrusive intervals were observed in the drill core. RC chips and drill core were logged on site and samples have been prepared for mineralogical studies and geochemical assay work to be completed at a laboratory in Perth, Australia. Results are pending. Mt. Edon Project (E59/2092)—The Mt. Edon Project is located in the South Murchison covers the southern portion of the Payne’s Find greenstone belt and hosts an extensive swarm of pegmatites. During Sayona Mining’s fiscal year ended June 30, 2022, Morella commenced exploration activities, mapping a total of 53 pegmatite outcrops. Rock chip assay results indicate the potential of the area for lithium mineralization. Pilbara Gold Tenements Sayona Mining’s Pilbara gold leases are prospective for intrusion related gold mineralization, similar in style to that identified at the Hemi gold discovery. This style of mineralization is hosted within altered late stage high-magnesium diorites. Sayona Mining’s tenement portfolio remains effectively untested for its gold potential with large areas masked by superficial cover. Mt. Dove Project (E47/3950)—The Mt. Dove project is within 3 miles of De Grey’s greater Hemi project area, a 19-mile trend which includes Hemi and adjacent intrusions. During the year, airborne magnetic surveys and geological mapping were undertaken which identified magnetic features for drill testing.
