Gold Fields has nine operating mines in Australia, Peru, South Africa and Ghana (including the Asanko JV) and two projects in Canada and Chile.
We have total attributable annual gold-equivalent production of 2.40Moz, attributable gold Mineral Reserves of 46.1Moz and Mineral Resources of 42.3Moz (excluding Mineral Reserves).
Sustainability for Gold Fields covers issues relating to our social licence to operate as well as mitigating the impact our operations have on the environment and adjacent communities
Our shares are listed on the Johannesburg Stock Exchange (JSE) and our American depositary shares trade on the New York Stock Exchange (NYSE).
We continually look for people who have a high performance attitude and can grow with us.
Our operations depend upon the reliable supply of responsibly produced products and services, and the know-how of experts in their field.

| Mining method | Open pit | Open pit | ||||
| Operational infrastructure | Cerro Corona mine operates one open pit and one copper-gold flotation plant. The mining administration and maintenance facilities are located at the mine. | Infrastructure consists of mine and plant facilities, warehouse, camp, offices, on-site power station, fuel station, a potable water plant and water treatment plant. Water is supplied from a well field 12km from the project. Power will be sourced from an on-site 26MW hybrid microgrid.The hybrid system consists of a 16MW diesel power station and a 7MW solar photovoltaic (PV) plant. The PV plant will be constructed during the first year of operation and commissioned towards the end of the projected process plant ramp-up. | ||||
| Mineral processing and TSFs |
The processing plant consists of a conventional primary crushing, semi-autogenous grind (SAG)/ball
milling and flotation circuit to generate a copper-gold concentrate. The final concentrate is thickened and
filtered before being stockpiled for road transport (380km) to the Salaverry port for shipment to copper
smelters in Japan and Germany. The thickened rougher flotation tails and the cleaner scavenger flotation
tails are transferred individually to the TSF.
TSF embankments are constructed in a downstream/centreline manner and located downstream from the process plant over the Las Gordas and Las Águilas gorges. The embankments (Las Gordas, Las Águilas and La Hierba) are being constructed progressively with borrow materials from limestone quarries. The embankments contain a clay core constructed from pit material (oxide material). The TSF has a remaining LOM storage capacity of ~26.4Mt up to 3,803m relative level (mRL). |
The process plant, designed to process 2Mtpa, will be located south-east of the main pit at ~4,500m
amsl. Ore will be crushed, milled and thickened with thickener underflow pumped to cyanide leaching.
Slurry from the leaching stage will feed a counter-current washing and solid liquid separation process
through a two-stage counter-current decantation (CCD) circuit. Metals in the solution will be recovered by
zinc precipitation in the Merrill-Crowe process. Soluble gold and silver remaining in the tailings slurry
obtained from the underflow of the second CCD stage will be scavenged by a CIP circuit. The dry stack TSF, located above the south mine WSF, has a total design capacity of 24Mt. Filtered tailings will be transported by trucks to the TSF, spread and allowed to dry to near their specific moisture content before being compacted. |
Cerro Corona mine – Peru
Cerro Corona’s life extension to 2030 is based on accelerated mining, enabled by the provision of waste storage capacity and extensive stockpile management so that from 2025 onwards, when the stockpile balance peaks, the LOM plan is based on ore processed from stockpiles with in-pit tailings disposal.
A study to assess the viability of further life extensions was initiated in 2021 and continued in 2022, focusing on a potential east wall pit cutback and further assessment of TSF and waste storage facility (WSF) capacities. These ongoing studies necessitated additional geotechnical drilling and pit wall mapping to define the morphology of low-competency limestones.
PROJECT
Salares Norte – Chile
Salares Norte is a high-grade, epithermal gold-silver, open-pit deposit situated in the High Andes of northern Chile. During April 2020, Gold Fields’ Board formally approved development of the Salares Norte project on the back of a positive FS and the approval of the environmental impact assessment (EIA) by the Chilean authorities. Salares Norte will have a significant impact on the future production profile of Gold Fields by accelerating growth in production and reducing AIC for the Group.
