India-focused miner Vedanta Resources is reportedly close to buying a 51-percent stake in oil producer Cairn India for $8 billion to $8.5 billion, a source familiar with the matter told Reuters. While neither Cairn Energy nor Vedanta would comment, the source said the deal is expected to be announced on Monday.

Cairn India was boosted by a huge oil find in Rajasthan that turned the company into a major oil producer and, according to Reuters, the deal “would be the diversified miner’s (Vedanta) first move into oil and gas.” Read the Reuters factbox on Cairn India here.
