Vedanta Resources plc, India`s largest producer of copper and zinc, said fiscal second-half profit rose 90% on higher metal prices and aluminium output.
Net income gained to US$486.6 million, from US$256.6 million a year earlier. The profit calculated from full-year figures reported on Wednesday by the London-based company, was in line with the US$486 million average of six analyst forecasts compiled by Bloomberg.
"Production across all metals will be better this year," chief executive officer Kuldip Kaura said in a conference call in London.
Growing Chinese metals demand helped the average copper price in the period rise 41% from a year earlier, while aluminium increased 24%.
Vedanta, controlled by billionaire Anil Agarwal, has also increased production, expanding output at its Korba aluminium smelter in India.
Aluminium for immediate delivery on the London Metal Exchange averaged US$2,721/t in the six months, and copper averaged US$6,522.
Zinc doubled, trading at a record. The stock has increased 16% this year, valuing the company at £4.07 billion (US$8.08 billion).
