This presentation may not form the basis of any contract or commitment whatsoever with any person. Distribution of this presentation may be restricted by applicable law. This presentation has been prepared by Piedmont Lithium Limited (“Piedmont”) as a summary only, and does not contain all information about Piedmont’s assets and liabilities, financial position and performance, profits and losses, prospects, and the rights and liabilities attaching to Piedmont’s securities. Any investment in Piedmont should be considered speculative and there is no guarantee that they will make a return on capital invested, that dividends would be paid, or that there will be an increase in the value of the investment in the future. Piedmont does not purport to give financial or investment advice. No account has been taken of the objectives, financial situation or needs of any recipient of this presentation. Recipients of this presentation should carefully consider whether the securities issued by Piedmont are an appropriate investment for them in light of their personal circumstances, including their financial and taxation position. Forward Looking StatementsThis presentation contains forward-looking statements within the meaning of securities legislation in Australia and the United States, including statements regarding exploration and development activities; plans for Piedmont’s mineral projects; projections of market demand and lithium prices; statements about the timing and amount of resource declarations; and statements about the timing and ability to complete scoping studies and feasibility studies. Such forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause actual events, results, performance or achievements to be materially different from events, results, performance or achievements expressed or implied by the forward-looking statements. Such factors include, among others, the risk that we will be unable to commercially extract mineral deposits, that our properties may not contain expected reserves, risks and hazards inherent in the mining business (including risks inherent in developing mining projects, environmental hazards, industrial accidents, weather or geologically related conditions), uncertainty about our ability to obtain required capital to execute our business plan, our ability to hire and retain required personnel, changes in the market prices of lithium, changes in technology or the development of substitute products, the uncertainties inherent in exploratory, developmental and production activities, including risks relating to permitting and regulatory delays, uncertainties inherent in the estimation of lithium resources, risks related to competition, as well as other uncertainties and risk factors set out in filings made from time to time with the Australian Stock Exchange and the U.S. Securities and Exchange Commission, including our most recent Form 20-F. Actual events, results, performance and achievements could vary significantly from the estimates presented in this presentation. Readers are cautioned not to put undue reliance on forward-looking statements. We disclaim any intent or obligation to update publicly such forward-looking statements, whether as a result of new information, future events or otherwise. Additionally, we undertake no obligation to comment on analyses, expectations or statements made by third parties in respect of Piedmont, its financial or operating results or its securities.Scoping Study Cautionary StatementsThe Scoping Study referred to in this presentation has been undertaken to determine the potential viability of an open pit mine, spodumene concentrator and lithium hydroxide plant constructed in North Carolina, USA and to reach a decision to proceed with more definitive studies. The Scoping Study has been prepared to an accuracy level of ±35%. The results should not be considered a profit forecast or production forecast. The Scoping Study is a preliminary technical and economic study of the potential viability of the vertically-integrated Piedmont Lithium Project. In accordance with the ASX Listing Rules, the Company advises it is based on low-level technical and economic assessments that are not sufficient to support the estimation of Ore Reserves. Further evaluation work including infill drilling and appropriate studies are required before Piedmont will be able to estimate any Ore Reserves or to provide any assurance of an economic development case. Approximately 55% of the total production target is in the Indicated Mineral Resource category with 45% in the Inferred Mineral Resource category. 100% of the production target in years 1-2 and 70% of the production target in years 3-6 are in the Indicated Mineral Resource category. The Company has concluded that it has reasonable grounds for disclosing a production target which includes an amount of Inferred material. However, there is a low level of geological confidence associated with Inferred Mineral Resources and there is no certainty that further exploration work (including infill drilling) on the Piedmont deposit will result in the determination of additional Indicated Mineral Resources or that the production target itself will be realised. The Scoping Study is based on the material assumptions outlined in the announcement made to ASX on July 19, 2018. These include assumptions about the availability of funding. While Piedmont considers all the material assumptions to be based on reasonable grounds, there is no certainty that they will prove to be correct or that the range of outcomes indicated by the Scoping Study will be achieved. To achieve the range outcomes indicated in the Scoping Study, additional funding will likely be required. Investors should note that there is no certainty that Piedmont will be able to raise funding when needed. It is also possible that such funding may only be available on terms that dilute or otherwise affect the value of the Piedmont’s existing shares. It is also possible that Piedmont could pursue other ‘value realisation’ strategies such as sale, partial sale, or joint venture of the Project. If it does, this could materially reduce Piedmont’s proportionate ownership of the Project. The Company has concluded it has a reasonable basis for providing the forward-looking statements included in this presentation and believes that it has a reasonable basis to expect it will be able to fund the development of the Project. Given the uncertainties involved, investors should not make any investment decisions based solely on the results of the Scoping Study.Cautionary Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred ResourcesThe information contained in this presentation 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”). Accordingly, 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/.

Piedmont confirms that: a) it is not aware of any new information or data that materially affects the information included in the original ASX announcements; b) all material assumptions and technical parameters underpinning Mineral Resources, Exploration Targets, Production Targets, and related forecast financial information derived from Production Targets included in the original ASX announcements continue to apply and have not materially changed; and c) the form and context in which the relevant Competent Persons’ findings are presented in this report have not been materially modified from the original ASX announcements.Exploration TargetThe Exploration Target is based on the actual results of Piedmont’s previous drill programs. To determine potential tonnage and grade ranges at the deposit, Li2O assay values and density values from drilling have been applied to the volume estimates. For the 80% of assays within pegmatite models that are above a 0.4 % Li2O cut off, an average grade of 1.10 % Li2O is estimated. For the 70% of assays that are above a 0.6 % Li2O cut off, an average grade of 1.20 % Li2O is estimated. Applying these assay frequency proportions to the modelled volumes outside the Mineral Resource results in estimated volume ranges from 1.75 million cubic meters to 2 million cubic meters for spodumene bearing pegmatite with economically interesting grades. A density value of 2.71 g/cm3 is applied to derive tonnage values.Using the above methodology an Exploration Target of between 4.75 to 5.5 million tonnes at a grade of between 1.10% and 1.20% Li2O is approximated for the Piedmont Lithium Project deposit. The potential quantity and grade of this Exploration Target is conceptual in nature, there has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
