Mining company Rio Tinto says it has produced record quantities of iron ore in the past quarter, thanks to a surge in demand from China.
The Anglo-Australian company said it produced 47.6 million tonnes of the ore in the three months to September.
China is continuing to import huge amounts of the ore for steel production.
Rio Tinto's Australia-listed shares rose to a two-year high in response to the news.
In London, its shares were up more than 1.5% in the first hour of trading.
Rio Tinto also reported record production of alumina and coking coal.
It said it was running its mining operations at full capacity in order to take advantage of current high commodity prices.
