"We remain on track to become the world's largest long-life integrated zinc-lead-silver producer in two years while maintaining our cost leadership. Our aluminium business continues to benefit from improved integration and systemic cost improvements," Vedanta Ltd Chief Executive Officer Srinivasan Venkatakrishnan said.
The company said revenue was 3 per cent lower on a quarter-on-quarter basis, primarily due to lower volumes in the oil and gas business.
"Revenue was three per cent lower on Q-o-Q basis, primarily due to lower volumes in oil and gas business, partially offset by higher volumes in iron ore and steel, zinc India and aluminium business coupled with past exploration cost recovery in oil and gas business," the statement said.
