BELMONT, NC, April 20, 2023Piedmont Lithium Inc. (“Piedmont” or the “Company”) (Nasdaq:PLL; ASX:PLL), a leading global developer of lithium resources, is pleased to report the results of a Definitive Feasibility Study (“DFS” or “Study”) of the Company’s proposed Tennessee Lithium project in McMinn County, Tennessee. The Study of the 30,000 metric ton per year (“tpy”) lithium hydroxide (“LiOH”) plant featuring the innovative and waste-reducing Metso:Outotec conversion technology affirms the potential for Piedmont to develop an American-based lithium hydroxide business using spodumene concentrate from market sources, including via existing offtake agreements with Sayona Quebec and Atlantic Lithium.

Study economics for Tennessee Lithium are shown in Table 1 below and are highlighted by an estimated after-tax NPV (8% discount rate) of $2.5 billion and an after-tax IRR of 32%. The Study assumes fixed prices of $26,000 per metric ton of lithium hydroxide and $1,600 per metric ton of spodumene concentrate over the project’s 30-year life. The model includes a Section 45X production tax credit of 10% under the Inflation Reduction Act of 2022 and assumes a credit of $141.7 million against project capital costs based on expected receipt of a U.S. Department of Energy (“DOE”) grant. Tennessee Lithium development remains subject to, among other things, receipt of material permits and arrangement of project financing.

Piedmont President and Chief Executive Officer Keith Phillips, said he was pleased with the project economics and the positive impact of the Inflation Reduction Act, which strongly favors domestic battery and critical minerals production. “America’s pro-EV and battery manufacturing policies are providing an advantage to Piedmont at a time when many analysts are projecting lithium shortages to continue into the 2030s. Piedmont’s selection for a $141.7 million grant last year by the U.S. Department of Energy exemplifies America’s commitment to developing a domestic lithium supply chain.[1]

“Tennessee Lithium is positioned to be a key resource for EV and battery manufacturers,” Phillips added. “Through long-term supply agreements with our partners, we can source raw material from spodumene that we own or in which we have an economic interest, providing greater control of our feedstock while capturing the economics of integrated production. We can advance development of the operation with revenues anticipated from the restart of North American Lithium and our recent offtake agreements with Tesla and LG Chem. Further, with the Metso:Outotec flowsheet, we believe we can sustainably produce critical lithium materials on a cost-effective basis for a more responsible profile compared to producers utilizing sulfuric acid roasting.”

Piedmont is advancing permitting and project financing activities for Tennessee Lithium with the goal of beginning construction in 2024. The Company is focused on first commercial shipments in Q3 from North American Lithium with revenue generation to support activities across Piedmont’s global portfolio of projects, including Tennessee Lithium. A DFS is expected mid-2023 for the Ewoyaa Lithium Project in Ghana, which is expected to be the primary feedstock for Tennessee Lithium, while Carolina Lithium continues to advance through permitting and approvals processes.

Tennessee Lithium 30,000 tpy Lithium Hydroxide Plant Overview

Tennessee Lithium will be located at the North Etowah Industrial Park in McMinn County, Tennessee. Piedmont agreed to purchase the 279-acre site situated between Chattanooga and Knoxville in August 2022. Figure 1 shows Tennessee Lithium’s location relative to Piedmont’s headquarters and Carolina Lithium project in Gaston County, North Carolina.

Figure 1 – Planned Tennessee Lithium Site Location in Etowah, Tennessee

The Project’s location in Tennessee was selected for several key reasons, including access to excellent infrastructure with convenient rail, road, and river transportation. The property is a CSX Select Site and a Select Tennessee Certified Site, ensuring that it meets high quality standards and is primed for development with documented environmental conditions and geotechnical analysis among other criteria. Further, the site is located in an Opportunity Zone, which gives Piedmont the ability to be a key contributor to the economic growth of the region.

The area also is home to a talented, industrial workforce with several nearby educational institutions to support workforce development objectives, including the Advanced Technologies Institute of Cleveland State Community College and the Tennessee College of Applied Technology – Athens.

Responsible power sources were another key criterion in the site selection process. Tennessee rated highly in this category due to the Tennessee Valley Authority’s aspiration to be net zero by 2050 and its commitment to replacing coal-fired generation with low-carbon resources, including nuclear, hydro, wind, and solar.

The site is in proximity to the “Battery Belt,” where battery and automotive plants are being constructed by prospective customers, and it is situated within a constructive business climate with cooperative local and state governments.

Figure 2 highlights examples of regional infrastructure as well as industries neighboring the industrial park.

Figure 2 –Industry and Infrastructure Near North Etowah Industrial Park

The DFS assumes that Tennessee Lithium will operate for 30 years and produce 30,000 tpy of lithium hydroxide at steady state from approximately 196,000 tpy of 6% Li2O spodumene concentrate (“SC6”) purchased at market rates from third parties. To support Tennessee Lithium operations, our strategy is to work with Atlantic Lithium to develop the Ewoyaa Lithium Project (“Ewoyaa”) in Ghana, where Piedmont holds offtake rights to 50% of spodumene concentrate production on a life-of-mine basis. Atlantic Lithium submitted an application for mining license to the Minerals Commission of Ghana for Ewoyaa in 2022 and expects to complete a definitive feasibility study in 2023 for the project.

In addition, spodumene concentrate may be purchased from Sayona Quebec, where Piedmont holds offtake rights for the greater of 113,000 tpy or 50% of spodumene concentrate production on a life-of-mine basis from North American Lithium (“NAL”) and the Authier Lithium Project. NAL restarted spodumene concentrate production in Q1 2023 and is expected to begin commercial shipments as early as Q3 2023.

While the strategy of the Company is to align operations in Tennessee Lithium primarily with the supply of spodumene concentrate from Ghana and secondarily with the supply from North American Lithium, the Project has the potential to accept spodumene concentrate from other market sources.

Process Design

Piedmont has selected Metso:Outotec’s innovative and proprietary alkaline pressure leach process, rather than traditional acid roasting, for production of lithium hydroxide at Tennessee Lithium. By eliminating the use of sulfuric acid, the pressure leach process is expected to reduce solid waste generation and overall air emissions. We believe our entire conversion method will be more efficient and environmentally sustainable than conventional acid-roasting spodumene-to-hydroxide technologies, resulting in a process that is safer for employees, the environment, and the community. While Metso:Outotec’s pressure leach process is new to the lithium industry, it has been proven in other applications, and we expect it will be adopted and proven by other lithium producers ahead of our timeline. All other unit operations, excluding the pressure leach within the process flowsheet, are currently widely employed in the lithium industry.

In 2021, Piedmont engaged Metso:Outotec to undertake pilot plant testwork using their pressure leach process based upon a spodumene concentrate sample derived from the Carolina Lithium project. In September 2022, Metso:Outotec began additional bench scale alkaline pressure leach testwork using spodumene concentrate samples sourced from Ewoyaa and NAL. Supplemental testwork on third-party concentrates is planned to support design basis and determine the impact of mineralogical/characteristic variability, however, the process is being designed to convert a wide variety of spodumene sources with minor adjustments. Based on the testwork completed, Metso:Outotec expects that 196,000 tpy of SC6 will be required to produce 30,000 tpy of battery quality lithium hydroxide, which allows this Study to assume a 91% lithium conversion rate through the lithium hydroxide conversion plant.

Site Plan

A preliminary site plan and 3D model (Figure 4) of the Tennessee Lithium plant, including lithium hydroxide manufacturing, rail siding, and ancillary facilities, was developed by Primero Group and Kiewit Engineering during the course of the Study. Layout optimization and value engineering are ongoing as part of front-end engineering design efforts.

Figure 4 – Isometric View of Tennessee Lithium



The proposed Tennessee Lithium site is located in the North Etowah Industrial Park in McMinn County, approximately 3.5 miles north of Etowah, Tennessee, and 6 miles southeast of Athens, Tennessee.

Etowah is located between Chattanooga and Knoxville, Tennessee, along the I-75 Corridor. Secondary roads connect Etowah to Athens, the closest access point to the Interstate. US Highway 411 runs through the city, paralleling the Interstate.

The North Etowah Industrial Park is a CSX Select Site, and the CSX main line track is adjacent to the Tennessee Lithium property. The CSX Select Site program reviews the most capable manufacturing and distribution development properties along the CSX network that can rapidly utilize freight rail service. The designation confirms that standard land use issues have been addressed and the site is ready for development.

Additionally, the site is in proximity to the Hiwassee River, which could provide an option for barge transportation via the Tennessee River system.


Power supply to the site will be via a 161kV transmission line tap on the Tennessee Valley Authority (“TVA”) transmission system. The line tap will be provided by Etowah Utilities and will connect to a new local substation on the Project site. The substation will have the main step-down transformers to reduce voltage from 161kV to 13.8kV for power distribution on site.

The Project is expected to purchase power from the City of Etowah via an existing distributor contract that Etowah has with TVA. The Company has entered into a deposit agreement with TVA with respect to providing preliminary engineering design of a special delivery point to the Project’s planned substation.

TVA has transformed its power generation mix from 36% carbon free in 2005 to 57% carbon free in 2020, while reducing carbon emissions by 70% during that time period. TVA reduced its reliance on coal-fired power from 57% in 2005 to 15% in 2020[2] as part of that change in the generation mix. TVA also offers industrial customers the opportunity to partner in green energy programs, including TVA Green Flex and TVA Green Invest.[3] Piedmont continues to evaluate these programs as opportunities to improve our overall emissions profile.

Waste Disposal Facilities

The study assumes that Piedmont will construct or acquire a storage facility for the analcime tailings from the pressure leach conversion process. These costs are included in the initial capital costs of the Project. The DFS also includes estimated costs to operate this facility as well as sustaining capital for storage facility maintenance and expansion during the 30-year Project life.

Piedmont continues to work with potential regional partners that could repurpose the analcime tailings for beneficial uses to reduce the Project’s solid waste profile and further lower production costs.

Natural Gas

The Company has entered into agreements securing capacity reservations for natural gas supply from the City of Etowah for firm-primary supply of 500 dekatherm/day of natural gas and a secondary capacity reservation of 4,350 dekatherm/day from Symmetry Energy Solutions. Excess natural gas requirements above these amounts will be provided by Symmetry Energy Solutions, if required.


Piedmont commissioned PLG Consulting (“PLG”) to evaluate various logistics alternatives for delivery of spodumene concentrate to Tennessee Lithium. PLG studied over 20 modal options for spodumene concentrate delivery to Etowah, Tennessee, including nine ocean ports and terminals, two river terminals, six barge operators, two stevedoring companies, three railroads, and truck delivery.

Based on PLG’s analysis, the Study has assumed that spodumene concentrate can be delivered by rail from several U.S. East Coast or Gulf ports and delivered by rail or truck to Etowah, Tennessee with barge transportation as an alternate delivery option.


As a Select Tennessee Certified Site, the property had already undergone a range of evaluations and analysis prior to Piedmont’s site selection to ensure that it is primed for development. The location within the North Etowah Industrial Park reduces the number of permits and approvals that Piedmont will need to independently secure to commence construction and operations at Tennessee Lithium.

In October 2022, the Company submitted an application for a Conditional Major Non-Title V Air Permit to the Tennessee Department of Environment and Conservation (“TDEC”). TDEC requested additional information related to our application in November 2022, and we responded in December 2022. In February 2023, TDEC deemed our application complete and subject to ongoing review. The Company also submitted a Construction Stormwater permit for the Project in March 2023. We expect to receive these permit approvals in Q2 or Q3 2023, allowing construction to commence once project financing has been arranged.

Certain height variances for structures may be required from McMinn County or the City of Etowah for the Project, depending on the final engineering design. Piedmont is currently collaborating with local officials and emergency response representatives regarding the potential requirements.


Lithium Market Outlook

Benchmark Mineral Intelligence (“Benchmark”) reports that total battery demand grew to nearly 590 GWh in 2022 translating to 540kt of lithium carbonate equivalent (“LCE”) demand in 2022, a growth of 55% over 2021 demand. Benchmark calculated total demand in 2022 to be 672kt on an LCE basis. Benchmark further expects the market to remain in a structural deficit (see Figure 5) as demand outpaces supply. In the near impossible scenario that all projects come online on time and as planned, without any issues, Benchmark projects a modest surplus in 2025-2027 before the market returns to a perpetual deficit without further new projects yet undiscovered or developed.

Figure 5 – Lithium supply demand forecast

Lithium prices have experienced volatility since Piedmont published the preliminary economic assessment (“PEA”) for LHP-2 (now referred to as Tennessee Lithium) in March 2022. Prices continue to show volatility, but current spot prices for battery-grade lithium hydroxide and spodumene concentrate remain above historical averages. Since the PEA was published, market analysts and industry consultants have largely revised their price forecasts for lithium hydroxide and spodumene concentrate higher over both the medium- and long-term to account for changing industry dynamics.

This Study assumes flat prices of $26,000/t for battery-grade lithium hydroxide and $1,600/t for spodumene concentrate for the life of the Project. The selected price deck represents a discount to current spot market prices and recorded sale prices disclosed by operating companies in the space. The price forecasts were developed based on a basket of market analysts and industry consultant medium- and long-term price forecasts, in addition to internal expectations around the future pricing environment. We believe that prices should remain elevated for several years based on increasing demand for lithium-ion batteries, a shortage of qualified supply, and the emergence of high-cost lepidolite and other alternative supply sources. Figure 6 compares the pricing used in the Study to historical pricing for lithium hydroxide and spodumene concentrate.

Figure 6 – Historical Battery Quality Lithium Hydroxide (ex-China) and Spodumene Concentrate Prices ($/t) as of April 18, 2023 (Fastmarkets)

As shown in Figure 7 below, North America is seeing considerable growth in battery plant capacity. Figure 8 below shows the corresponding lithium hydroxide demand given the expected capacity of the announced U.S. battery manufacturing plants at full production, reflecting dramatic growth from the current installed capacity base in the U.S. of approximately 20,000 tpy.

Market Strategy

Piedmont is focused on establishing strategic partnerships with customers for battery grade lithium hydroxide with an emphasis on a customer base that supports EV demand growth in North America and Europe. Piedmont expects to concentrate this effort on these growing EV supply chains, particularly considering the increasing commitments of battery and battery material manufacturing by groups such as Tesla, Ford, General Motors, Stellantis, Volkswagen, Toyota, LG Energy Solutions, LG Chem, SK Innovation, Samsung SDI, and others. Discussions with prospective customers and strategic parties are ongoing.

Project Schedule

Overall schedule development of the Tennessee Lithium project has been completed to a DFS level. An anticipated summary schedule is presented in Figure 10. Piedmont expects to complete front-end engineering design by the end of Q3 2023. Concurrent with completing FEED, Piedmont plans to begin detailed design engineering for the Project. Ordering of long-lead equipment and EPC execution will occur upon completion of permitting and project financing activities.

The Project schedule remains subject to ongoing design engineering, permitting approvals, spodumene concentrate supply sourcing, EPC contract negotiation, market conditions, and project financing activities.

Figure 10 – Indicative Tennessee Lithium Project Schedule

Taxes and Depreciation

Tennessee Lithium project economics include, but are not limited to, the following key parameters related to taxes and depreciation allowances.

  • Model assumes Tennessee state corporate taxes of 6.5%.
  • The Federal tax rate of 21% is applied and state corporate taxes are deductible from this rate.
  • Depreciation in the lithium hydroxide plant is based on Asset Class 28.0 – Mfg. of Chemical and Allied Products in Table B-1 using GDS of 5 years with the double-declining balance method.
  • Bonus depreciation of 80% has been applied based on the bonus depreciation allowance in the Tax Cuts and Jobs Act of 2017, where applicable.
  • A 10% production tax credit under Section 45X of the Inflation Reduction Act has been included in the financial model. The tax credit is applied to all operating costs, including spodumene concentrate purchases.

Modeling Assumptions

A project economical model was completed by Primero as part of the Study with the following key assumptions:

  • Capital and operating costs are in accordance with technical study outcomes.
  • Chemical plant ramp-up is based on a 12-month timeframe to nameplate production.
  • Financial modeling has been completed on a yearly basis, including estimated cash flow for construction activities and Project ramp-up.
  • Pricing information for battery-grade lithium hydroxide sales and spodumene concentrate supply are based on a fixed price of $26,000/t for battery quality lithium hydroxide and $1,600/t for 6.0% Li2O spodumene concentrate.
  • Taxes and depreciation allowances according to stated assumptions.

Financial Modelling

The DFS assumes a chemical plant production life of 30 years as well as operations using market procurement of SC6, including potentially from offtake sources currently controlled by or contracted with Piedmont.

The current economic model is based on a yearly projection of capital costs and assumes that the full capital cost is spent across 2 years prior to commissioning the chemical plant. The chemical plant is assumed to ramp up to full production over a one-year period.

Payback Period

The payback period for Tennessee Lithium is estimated to be 2.8 years after the start of chemical plant operations or 5.3 years from the start of construction. The payback period is calculated based on after-tax free cash flow.

Sensitivity Analyses

Key inputs in the DFS have been tested by pricing, capital cost, and operating cost sensitivities. The impact to after-tax net present value (“NPV”) is presented in Figure 11, while the impact to Project internal rate of return is presented in Figure 12. Additionally, applying discount rates of 7% and 9% resulted in NPV7 of $2,851mm and NPV9 of $2,185mm.

Figure 12 – Tennessee Lithium Internal Rate of Return Sensitivity Analysis

Conclusions and Next Steps

The Tennessee Lithium DFS Study results demonstrate a robust technical and financial case for Piedmont to establish a merchant lithium hydroxide manufacturing business in the United States using spodumene concentrate from market sources, including the existing offtake agreements secured by the Company in 2021. The Company will now undertake the following activities with a view to a possible Final Investment Decision in 2024:

  • Complete front-end engineering design.
  • Continue permitting activities associated with the Project.
  • Undertake additional pilot testwork programs with Metso:Outotec.
  • Begin detailed design engineering.
  • Continue project financing discussions.

Piedmont Lithium Partner Sayona Announces Positive NAL DFS And Increased Resource at Moblan

  • Definitive Feasibility Study of spodumene concentrate production at North American Lithium increases annual production targets in advance of first shipments to customers
  • JORC and NI 43-101 compliant Measured & Indicated Mineral Resources at Moblan increased to 41.1 million metric tons @ 1.32% Li2O at a cut-off grade of 0.55% Li2O

Belmont, North Carolina, April 18, 2023Piedmont Lithium Inc. (“Piedmont” or the “Company”) (Nasdaq:PLL; ASX:PLL), a leading global developer of lithium resources, today announced that the Company’s joint venture partner, Sayona Mining (“Sayona”) (ASX:SYA), has released a definitive feasibility study (“DFS”) for the jointly-owned North American Lithium (“NAL”) project, and increased lithium mineral resources at its 60%-owned Moblan Lithium Project (“Moblan”), both in the province of Quebec. Piedmont holds a 25% stake in NAL and an equity interest of approximately 14% in Sayona. Sayona completed the technical studies for NAL and Moblan in accordance with both JORC Code and NI 43-101 requirements.

The NAL DFS contemplates increased annual spodumene concentrate production averaging 190,000 metric tons per year (“tpy”) over a 20-year mine life, with a target of 226,000 tpy in years one through four of steady state operations and approximately 186,000 tpy beginning in year five. The revised production targets, combined with higher spodumene concentrate pricing, resulted in an increase to the net present value for the NAL project compared to the prefeasibility study completed in 2022.

As part of the DFS and mine restart efforts, Sayona undertook a strategic review of mineral resources and ore reserves to create opportunities to focus on higher-grade, open-pit material and to improve project net present value. The revised block model has resulted in a reduction in ore reserves and certain Indicated Resources have been reclassified as Inferred Resources based on new model interpretation. The study contemplates a mine life of 20 years, reduced from the prefeasibility study estimate of 27 years, through the elimination of underground mining.

NAL is one of the projects of Sayona Quebec, a joint venture between Sayona (75%) and Piedmont (25%). Piedmont holds an offtake agreement with Sayona Quebec to purchase the greater of 113,000 tpy or 50% of the joint venture’s spodumene concentrate production. Piedmont subsequently has agreements with LG Chem and Tesla to provide spodumene concentrate from NAL beginning in H2 2023. Sayona Quebec is undertaking a prefeasibility study to explore downstream production at NAL and expects results in Q2 2023.

Separately, Sayona has announced a significant increase in mineral resources at its 60%-owned Moblan project in northern Quebec. Measured and Indicated Mineral Resources at Moblan now total 41.1 million metric tons @ 1.32% Li2O using a 0.55% Li2O cut-off grade, making Moblan one of North America’s most significant spodumene ore bodies.

Piedmont’s Chief Operating Officer Patrick Brindle said, “The results of the DFS underscore NAL’s role as a significant lithium producer positioned to meet the requirements of the Inflation Reduction Act of 2022. Production is ramping up at NAL, and we look forward to making initial shipments to our customers LG Chem and Tesla later in 2023. Further, we congratulate our partners at Sayona on the significant mineral resource expansion at their 60%-owned Moblan project. We are very pleased with our positions as Sayona’s joint venture partner in the Abitibi Hub lithium projects and as Sayona Mining’s largest shareholder. Quebec is an ideal location for lithium chemicals in the future, given the province’s abundant mineral resources, low-cost hydroelectricity, proximity to U.S. markets, and supportive provincial government.”

Cautionary Note to U.S. Investors

Piedmont’s public disclosures are governed by the U.S. Exchange Act of 1934, including Regulation S-K 1300 thereunder, whereas Sayona discloses estimates of “measured,” “indicated,” and “inferred” mineral resources as such terms are used in the JORC Code and Canada’s National Instrument 43-101. Although S-K 1300, the JORC Code, and NI 43-101 have similar goals in terms of conveying an appropriate level of confidence in the disclosures being reported, they at times embody different approaches or definitions. Consequently, investors are cautioned that public disclosures by Sayona prepared in accordance with the JORC Code or NI 43-101 may not be comparable to similar information made public by companies, including Piedmont, subject to S-K 1300 and the other reporting and disclosure requirements under the U.S. federal securities laws and the rules and regulations thereunder.
