Strategic Review Supports Continued Production Ramp-Up at North American Lithium

Piedmont Lithium (“Piedmont” or the “Company”) (Nasdaq: PLL; ASX: PLL), a leading global supplier of lithium resources critical to the U.S. electric vehicle (“EV”) supply chain, announced that, following a detailed operational review, the joint venture partners of North American Lithium (“NAL”) have agreed to complete several ongoing capital project initiatives and continue operations with the goal of completing ramp-up activities to achieve steady state production within 2024.

NAL is jointly owned by Piedmont (25%) and Sayona Mining (ASX: SYA) (75%). Production at NAL commenced in March 2023, and the operations have been undergoing steady improvement. Process plant recoveries are now exceeding internal expectations, a key achievement in NAL’s ramp-up process. March month-to-date lithium recoveries were 69%, exceeding the ramp-up target of 67%, with global recovery of 62% during the July 2023 through March 2024 period. Production of spodumene concentrate has steadily increased with several daily production records achieved in March 2024, including the newest daily production record of 740 metric tons. Current plant throughput rates are in line with forecast expectations at 161 tonnes per hour and product quality remains consistent at 5.45% Li₂O with moisture and other elements in line with expectations.

The joint venture partners have conducted an operational review to assess the pace of the production ramp-up in the context of a challenging lithium price environment. The review concluded that operations are generally ramping-up as planned, and that completion of two important capital improvement projects – a crushed ore storage dome and crushed ore re-feed system, both expected to be commissioned in May 2024 – should help operations achieve production increases and meaningful unit cost improvements. Unit mining costs also are expected to improve as operations move past underground workings and into fresh ore near the end of 2024.

“As the largest producing spodumene mine in North America, NAL is strategically important to our portfolio, our customers, and the market,” said Keith Phillips, President and Chief Executive Officer of Piedmont Lithium. “NAL production has been ramping up well, albeit in a challenging lithium market. With the imminent completion of important capital improvement projects expected to lead to production increases and operating cost improvements, we believe the project is well-positioned for the market recovery we anticipate and to operate successfully over the long term.”
