China National Gold studies bid for Canadian miner Iamgold

China National Gold Group, the nation’s second-biggest miner of the metal, is studying a bid for a stake in Canada’s Iamgold, people familiar with the matter said. Iamgold shares jumped the most in more than four years.

The state-owned gold miner is working with financial advisers on the potential offer, the people said, asking not to be identified as the information is private. Iamgold is exploring a possible sale of all or part of the company and has spoken to several potential buyers, Bloomberg News reported last month.
