Vedanta Resources Plc
However, shares in the company fell as much as 5% after Morgan Stanley cut its rating on the stock to "underweight" from "equal weight" citing a stretched valuation for its Konkola Copper Mines (KCM) assets in Zambia.
"Vedanta has re-rated strongly versus peers since January 2012...As a result the implied valuation of its KCM copper asset is now at a premium to the global copper peer group," Morgan Stanley analysts said in a note to clients.
Copper cathode production at its India unit fell about 6% to 82,000 tonne in the second quarter. Mined metal production at its Zambia unit fell 26% to 34,000 tonne.
The company also cut its full-year copper production outlook from Zambia to 140,000 tonne from 160,000 due to the ongoing suspension of its Chingola F&D pits and slow ramp-up at the Konkola mine.
The stock was down 4% at 1027 pence at 0855 GMT on the London Stock Exchange.
