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.

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 Persons StatementsThe information in this presentation that relates to Exploration Results is extracted from the Company’s ASX announcements dated August 23, 2018, July 19, 2018, June 14, 2018, June 7, 2018, May 17, 2018, May 10, 2018, April 9, 2018, 4 April 2018, 15 March 2018, 1 December 2017, 2 November 2017, 27 September 2017, 23 May 2017, 3 April 2017, and 18 October 2016 which are available to view on the Company’s website at The information in this presentation that relates to Exploration Targets and Mineral Resources is extracted from the Company’s ASX announcement dated June 14, 2018 which is available to view on the Company’s website at The information in this presentation that relates to Metallurgical Testwork Results is extracted from the Company’s ASX announcements dated September 4, 2018 and July 17, 2018 which are available to view on the Company’s website at The information in this presentation that relates to Process Design, Process Plant Capital Costs, and Process Plant Operating Costs is extracted from the Company’s ASX announcements dated September 13, 2018 and July 19, 2018 which are available to view on the Company’s website at The information in this presentation that relates to Mining Engineering and Mine Schedule is extracted from the Company’s ASX announcements dated September 13, 2018 and July 19, 2018 which are available to view on the Company’s website at 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 this methodology an Exploration Target of between 4.5 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.    35
