The family trust of the founder of India's largest mining company plans to ramp up its investment in Anglo American PLC by as much as $2 billion, making it the biggest investor in the British mining company that has benefited from a recovery in commodity prices. The investment follows a $2.44 billion investment in March by Volcan Investments Ltd., the family trust of Vedanta Resources PLC founder and Chairman Anil Agarwal, putting its stake in Anglo American at about 20%. While the new stake is likely to ramp up speculation that the billionaire mining titan has plans to take over Anglo American, Mr. Agarwal's trust said it has no plans to make an offer to acquire the Anglo in the future. The second-biggest Anglo investor, Public Investment Corp., South Africa's state-run pension fund, holds about 13% of the company, according to FactSet. Anglo American shares have gained about 9% since Mr. Agarwal made his initial investment in March. "We are encouraged by the performance of Anglo American since our original investment earlier this year," Mr. Agarwal said in a statement. A spokesman for Anglo American declined to comment.via
