About Piedmont Lithium

Piedmont Lithium Limited (ASX:PLL; Nasdaq:PLL) holds a 100% interest in
the Piedmont Lithium Project located within the Carolina Tin-Spodumene Belt (“TSB”) and along trend to the Hallman Beam and Kings Mountain
mines, which historically provided most of the western world’s lithium between the 1950s and the 1980s. The TSB has been described as one of
the largest lithium regions in the world and is located approximately 25 miles west of Charlotte, North Carolina.

In September 2018 the Company published a Scoping Study for an
integrated lithium hydroxide business based on a maiden Mineral Resource estimate of 16.2 million tonnes (“Mt”) grading at 1.12% Li2O which
featured a 13-year project life, NPV8 of US$888 million, a US$3,112 per tonne lithium hydroxide operating cost, and a US$193 per tonne spodumene
concentrate operating cost.
