Piedmont Lithium ("Piedmont" or the "Company") (Nasdaq: PLL; ASX: PLL), a leading North American supplier of lithium products critical to the U.S. electric vehicle supply chain, today announced that it shipped approximately 15,500 dry metric tons ("dmt") of spodumene concentrate in Q1'24 as North American Lithium ("NAL") achieved new quarterly and monthly production records in its ongoing ramp up to steady-state operations. NAL is forecasted to achieve full run-rate production by H2'24.¹ Based on this projection and per its offtake agreement, Piedmont expects to ship approximately 126,000 dmt of spodumene concentrate in 2024, weighted toward the second half of the year and with quarterly variations due to shipping logistics and customer requirements. The Company is prioritizing contract customer shipments to reduce reliance on volatile spot markets.

Q1'24 Operational Results Summary

In Q1'24, NAL produced 40,439 dmt and shipped 58,055 dmt, of which approximately 15,500 dmt of spodumene concentrate were sold to Piedmont via the Company's offtake agreement and shipped to Piedmont customers. An approximately 13,200 dmt shipment held over from 2023, combined with our contracted 113,000 dmt annual offtake from NAL, underpins Piedmont's plan for full-year shipments of approximately 126,000 dmt of spodumene concentrate in 2024.

NAL increased quarterly production by 18% in Q1'24 compared to the prior quarter. Safety performance also improved as NAL achieved its lowest quarterly recordable incident rate since the start of operations in March 2023.

Notably, March 2024 was a record production month at NAL with 15,699 dmt of spodumene concentrate produced and three daily production records set between 710 dmt and 750 dmt. Lithium recoveries also reached a record 69% during March 2024.

Construction of the crushed ore dome is materially completed with commissioning underway and expected to conclude in Q2'24. This capital project is expected to result in continued improvements in mill utilization and further increases in quarterly production levels.

"NAL is the largest producing spodumene operation in North America, and as such, is a tremendously strategic asset. We are pleased to see production continue to set quarterly records and hopeful that NAL will hit steady-state production targets with the commissioning of the crushed ore dome," said Keith Phillips, President and CEO of Piedmont Lithium. "We are optimistic about the recent upturn in lithium prices, and we look forward to commencing regular shipments to our contract customers as the year progresses."
