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/.Competent Persons StatementsThe information in this presentation that relates to Exploration Results is extracted from the Company’s ASX announcements dated August 7, 2019, August 1, 2019, June 25, 2019, June 18, 2019, May 29, 2019, April 24, 2019, March 14, 2019, February 13, 2019, October 17, 2018, 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 www.piedmontlithium.com. The information in this presentation that relates to Exploration Targets and Mineral Resources is extracted from the Company’s ASX announcements dated August 1, 2019, June 25, 2019 and April 24, 2019 which are available to view on the Company’s website at www.piedmontlithium.com. The information in this presentation that relates to Metallurgical Testwork Results is extracted from the Company’s ASX announcements dated August 7, 2019, July 17, 2019, June 18, 2019 which are available to view on the Company’s website at www.piedmontlithium.com. 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 announcement dated August 7, 2019 which is available to view on the Company’s website at www.piedmontlithium.com. The information in this presentation that relates to Mining Engineering and Mining Schedule is extracted from the Company’s ASX announcement dated August 7, 2019 which is available to view on the Company’s website at www.piedmontlithium.com.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. A density value of 2.71 g/cm3 is applied to derive tonnage values. Using this methodology an Exploration Target of between 4.0 to 4.5 million tonnes at a grade of between 1.10% and 1.20% Li2O is approximated for the Core property and an Exploration Target of between 2.0 to 2.5 million tonnes at a grade of between 1.1% and 1.3% Li2O is approximated for the Central property. 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.    27
