Diversified miner Xstrata Plc said on Wednesday it was offering to buy the 80 percent of Canadian nickel miner Falconbridge it does not own for C$16.1 billion ($14.4 billion) in cash.
Switzerland-based Xstrata became Falconbridge's largest shareholder last August when it bought a 20 percent stake and had been expected to enter the battle for Falconbridge against rival Canadian miner Inco.
