NAL CONCENTRATE PRODUCTION

Q1’25 OPERATIONAL RESULTS SUMMARY

In Q1’25, NAL produced 43,261 dmt and sold approximately 27,000 dmt. All tons sold by NAL were sold to Piedmont under the Company’s offtake agreement and then shipped to Piedmont’s customers.

Quarterly production at NAL declined by 15% in Q1’25 compared to the prior quarter but production remains on track to achieve Sayona Mining’s fiscal year 2025 production guidance of 190,000 – 210,000 dmt². Lithium recovery remained high at 69% and set a new record of 72% in March, while mill utilization declined due the combination of unplanned, weather-related downtime and a 5-day scheduled shutdown. The crushed ore dome mitigated the impact of the weather-related downtime and additional mobile crushing capacity has been brought on site to lessen the impact of weather on a go-forward basis.

“While NAL operated under challenging conditions to begin 2025 and produced fewer tons than anticipated, adjustments implemented since the restart of production have improved operational resilience. These steps give us confidence in our ability to improve performance and reduce weather-related disruptions in the future,” said Keith Phillips, President and CEO of Piedmont Lithium.
