NEW YORK – Piedmont Lithium Limited (ASX: PLL; NASDAQ: PLL) (“Piedmont” or “Company”) is pleased to present its September 2019 quarterly report. Highlights during and subsequent to the quarter were:

• Completed an updated Scoping Study for the fully-integrated Project, which was managed by independent consultants, Primero Group Limited, and delivered outstanding results including:
  • a 25-year mine life and compelling economics including an NPV of US$1.45 billion and an after-tax IRR of 34%, due to attractive capital and operating costs;
  • a chemical plant producing 22,700tpa of lithium hydroxide supported by an open pit mine and concentrator producing 160,000tpa of 6% spodumene concentrate; and
  • by-product quartz (86,000tpa), feldspar (125,000tpa), and mica (13,000tpa) providing credits to the cost of lithium production;
• In response to strong interest from prospective lithium hydroxide customers, the Company has decided to accelerate development of its lithium chemical plant by compressing its project timeline into a single-stage, effectively accelerating chemical plant development by one year while deferring the mine/concentrator construction start date by one year, resulting in integrated operations from day one.
• Completed PFS-level metallurgical test work demonstrating high quality spodumene concentrate product with a grade above 6.0% Li₂O, iron oxide below 1.0%, and low impurities from representative samples using a combination of Dense Medium Separation (“DMS”) and flotation technology;
• Continued the 25,000-meter Phase 4 drill program, where a total of 103 holes have been completed to date for a total of 17,187 meters;
• Completed Mineral Resource estimates and bench-scale metallurgical testwork for by-product quartz, feldspar and mica as by-products of spodumene concentrate from the Project. The Mineral Resource estimates were prepared by independent consultants, CSA Global Pty Ltd;
• Continued numerous preliminary off-take, financing and strategic conversations, including companies from the lithium, mining, chemicals, battery, automotive and private equity sectors;
• Completed an institutional placement of 145 million shares at A$0.145 per share to raise gross proceeds of A$21 million, led by cornerstone investor, Fidelity International (“Fidelity”) and the Company’s largest shareholder, AustralianSuper.

Next steps:

• Complete permitting to commence mining and processing operations at the Project;
• Commence permitting for the chemical plant in Q4 2019;
• Commence lithium hydroxide testwork in Q4 2019;
• Complete pre-feasibility study (“PFS”) for the chemical plant in Q2 2020;
• Continue offtake discussions for lithium hydroxide with participants in the global battery supply chain; and
• Continue to evaluate strategic partnering options.
