(Corrects first paragraph to show core earnings at Vedanta’s copper business in Zambia fell, not the overall copper business)
July 30 (Reuters) - 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. (Reporting by Karen Rebelo in Bangalore; Editing by Robin Paxton)
