China's Zijin agrees to buy Canada's Continental for C$1.3bn

China's Zijin Mining Group Co has agreed to buy Canadian miner Continental Gold for C$1.3-billion, but a top executive with the target company said elevated security concerns in Colombia pose a risk to the deal.

State-backed Zijin's offer for Continental, announced on Monday, aims to secure Continental Gold's flagship Buritica gold project in Colombia.
