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 seeks to make up for expected declines in production from its existing projects.
With the acquisition, Gold Fields will add projects in Canada, Brazil, Argentina and Chile to its mines in South Africa, Ghana, Australia and Latin America. The combined company, which will be based in Johannesburg, will have a market capitalization of $15.9 billion, making it the world’s fourth-largest gold miner, behind Newmont Barrick Gold and Agnico Eagle Mines
