Lynas made 1,857 tonnes of NdPr in the June 2026 quarter, down from 1,996 tonnes, after problems with Mt Weld's new water recycling plant and a change in ore that lowered concentrate quality. The weaker feed cut the productivity of cracking and leaching in Kalgoorlie and Kuantan. The water issues were fixed, and Kalgoorlie commissioned a continuous precipitation process.

## Key facts

- Total rare-earth oxide: 3,481 t; Dy and Tb: 19 t.
- A fixed crusher replaced a mobile one, reducing ore sorting before the mill.
- New fine-grinding mill due in Q1 FY27 to lift recoveries.
- Mt Weld hybrid power averaged 90% renewable in the quarter.
