Gold Fields plans to extend life of Peru mine through 2040

South African miner Gold Fields aims to extend the life of its Cerro Corona gold mine in Peru through 2040 with an investment of at least $240-million, the company's vice president for the Americas said late on Wednesday. "We're doing studies with Peruvian consulting firms and international engineering companies to extend the life of Cerro Corona until 2040," Luis Rivera told journalists at an event. "It's going to involve the use of new technologies."
