During 2011, Gold Fields Corona (BVI) Limited, a wholly owned subsidiary of Gold Fields Limited, increased its economic interest in Gold Fields La Cima S.A.A., or La Cima, from 80.7% to 98.5%. La Cima holds the Cerro Corona mine, which is located approximately 600 kilometres northnorthwest of Lima and approximately 80 kilometres by road north of Cajamarca city.

The Cerro Corona mine is a large open-pit mine situated in the highest part of the Western Cordillera of the Andes Mountains in Northern Peru, approximately 1.5 kilometres west-northwest of the village of Hualgayoc in the Department of Cajamarca. Access to the Cerro Corona mine from Cajamarca is by means of two roads, one from Cajamarca to the Yanacocha mine (40 kilometres), and then from Yanacocha to the village of Hualgayoc (40 kilometres). The deposit is hosted by a subvertical, cylindrical-shaped diorite porphyry (600 – 700 metres in diameter), emplaced in mid-Cretaceous limestone, marls and siliciclastic rocks.

The mine is expected to produce approximately 2.0 million saleable ounces of gold and 423,000 saleable tonnes of copper in concentrate over a 17-year Life of Mine (LoM). At the declared commodity prices, the estimated copper and gold Mineral Reserves are equal to a total of 6.1 million gold equivalent ounces. The plant has a production capacity of 19,200 tonnes of ore per day, or about 6.6 million tonnes of ore per year.
