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

• Increased total Mineral Resources for the Piedmont Lithium Project (“Project”) by 72% to 27.9 million tonnes (“Mt”) at a grade of 1.11% Li2O following:
  • anupdated Mineral Resource estimate for the Company’s Core property, increasing the Core property Mineral Resources to 25.1 Mt at a grade of 1.09% Li2O; and
  • an initial Mineral Resource estimate for the Company’s Central property, located approximately one mile south of the Core property, of 2.8 Mt at a grade of 1.34% Li2O.
• Completed mineralogical analysis on samples of mineralized pegmatites and composite samples from the Project demonstrating that lithium occurs almost exclusively within spodumene in the Project’s ore body.
• 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 bulk 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 94 holes have been completed to date for a total of 15,738 meters.
• Substantially completed engineering for the planned Scoping Study update to integrate updated Mineral Resources, latest metallurgical testwork, flowsheet optimization and updated costs.
