Lynas Rare Earths (ASX:LYC) reported a 30% drop in neodymium-praseodymium output to 1,404 tonnes for the quarter, following power disruptions at its Kalgoorlie facility and planned maintenance in Kuantan.
The decline, foreshadowed in November, dragged overall rare earth oxide production down to 2,382 tonnes.
Dysprosium and terbium output reached 26 tonnes, as work-in-progress from the previous quarter was processed alongside new production.
Despite lower volumes, average rare earths selling prices rose sharply to $85.60 per kilogram, up from $54.30 in the September quarter, driven by stronger benchmark pricing and a higher proportion of non-index sales.
Quarterly gross sales revenue totalled $201.9 million, with sales receipts of $185 million.
The company ended the quarter with $1.03 billion in cash and short-term deposits, while cash payments for capital expenditure, exploration, and development amounted to $45.2 million.
Operationally, Lynas reported that kiln maintenance in Malaysia is complete, power supply in Kalgoorlie has stabilised, and the Mt Weld expansion has reached 70% of its nameplate capacity.
