_{⁽¹⁾Tonnes = finished product tonnes}

For the first quarter, potash sales volumes and MOP prices at the mine are expected to be within the previous guidance range of 2.0-2.2 million tonnes, and $225-$250 per tonne, respectively.

In Phosphates, first quarter sales volumes are expected to be within the previous guidance range of 1.6-1.8 million tonnes. Included in that estimate are 175,000 to 200,000 tonnes of low margin products purchased from third parties to offset the impact of our previously announced turnaround schedule in the first half of 2024. DAP prices at the plant are expected to be within the previous guidance range of $580-$605 per tonne.

Looking ahead, our Riverview phosphate fertilizer production facility, which has a run rate of approximately 30,000 tonnes per week, sustained limited damage to ancillary operations from a brushfire earlier this week. Production impacts associated with the incident may last four to six weeks. At the time of the fire, the facility was configured to produce phosphate products primarily for export to Brazil.
