Piedmont Lithium : Hires First Tennessee Employees

Lee Montgomery joins as Community Relations Manager;
Ashley Copeland joins as Corporate Communications Specialist

BELMONT, NC, January 24, 2023 - Piedmont Lithium ("Piedmont" or the "Company") (Nasdaq:PLL; ASX:PLL), a leading global developer of lithium resources critical to the U.S. electric vehicle ("EV") supply chain, today announced the addition of its first Tennessee-based employees to support the Tennessee Lithium project. Piedmont announced plans last September to build the 30,000 metric ton per year ("tpy") lithium hydroxide operation in the City of Etowah in McMinn County, Tennessee to support domestic production of battery-grade lithium.

Lee Montgomery joins Piedmont Lithium as a Community Relations Manager and Ashley Copeland as a Corporate Communications Specialist. Both Montgomery and Copeland are residents of McMinn County, underscoring Piedmont's commitment to hiring locally whenever possible.

Keith Phillips, President and CEO of Piedmont, said these additions mark an important step in the Company's efforts to establish a presence in the region. "We're excited to welcome our first Tennessee-based employees to the Piedmont team," explained Phillips. "Lee and Ashley, as valued and active members of Etowah and McMinn County, are well suited to play a critical role in engaging with and informing the community as we advance our Tennessee Lithium project."

Piedmont was selected for a $141.7 million grant by the United States Department of Energy for the Tennessee Lithium project in October 2022. The Company is currently in the process of negotiating the grant terms. When finalized, the funding is expected to support detailed engineering and orders for the project's long-lead items.

Tennessee Lithium is being designed as a world-class lithium hydroxide operation that will more than double the total lithium hydroxide production capacity of 20,000 tpy currently available in the U.S. The operation is expected to create 120 new, direct jobs. Construction is targeted to begin in 2023, subject to permitting and project financing, with first production targeted for 2025.
