JOHANNESBURG—South Africa-based miner Gold Fields said Tuesday it has agreed to buy Yamana Gold in an all-stock deal that values the Canadian company at $6.7 billion, as it continues to expand its operations outside South Africa.
Gold Fields said the combined company, which will be based in Johannesburg, will have mines in Canada, Australia, Ghana, South Africa and across South America and a market capitalization of $15.9 billion. Gold Fields said the new company would be the world’s fourth-largest gold miner, behind Newmont Barrick Gold and Agnico Eagle Mines
