Corrected - Vedanta first-quarter core earnings rise marginally

REUTERS - (Corrects first paragraph to show core earnings at Vedanta's copper business in Zambia fell, not the overall copper business)

Diversified miner Vedanta Resources Plc ground out a marginal increase in quarterly core earnings as its oil and gas and aluminium businesses offset a decline in its zinc and Zambian copper businesses.

Earnings before interest, tax, depreciation and amortisation (EBITDA) rose to $1.04 billion for the quarter ended June 30 from $1.03 billion a year earlier.

Revenue increased 7 percent to $3.06 billion.
