Media Release The Australian region produced 258koz at AIC of A$1,707/oz (US$1,159/oz) and AISC of A$1,517/oz (US$1,029/oz). On a managed basis, our mines in Ghana produced 215koz (including 45% of Asanko) at AIC of US$1,134/oz and AISC of US$1,101/oz. Cerro Corona in Peru produced 60koz (gold equivalent) at AIC of US$1,035 per gold equivalent ounce and AISC of US$948 per gold equivalent ounce. South Deep reported managed production of 88koz at an AIC of R649,812/kg (US$1,176/oz) and AISC of R624,701/kg (US$1,131/oz). Gold Fields remains in a strong financial position During Q3 2022, there was an increase in the net debt balance (including leases) to US$997m at 30 September 2022 from US$851m at 30 June 2022, mainly due to the interim dividend payment of US$151m. This translates into a net debt to EBITDA of 0.40x, compared to 0.33x at 30 June 2022. The net debt balance (excluding leases) increased to US$603m from US$451m at the end of June 2022. Salares Norte Q3 2022 construction activities at Salares Norte were again impacted by Covid together with severe weather conditions that flowed over from the second quarter. US$80.5m was spent on the project during the quarter, comprising mainly US$70.9m in capital expenditure, US$3.5m in exploration, a US$3.7m investment in working capital and a realised loss of US$3.7m on the forex hedge. A total of US$253m was spent on the project during the nine months ended 30 September 2022. Total project progress stood at 82.0% at the end September compared to 77.0% at the end of H1 2022. Construction progressed 7.0% during the September quarter, impacted by various snow and white wind events in July and STATEMENT BY CHRIS GRIFFITH, CEO SALIENT FEATURES Operational update For the quarter ended 30 September 2022 high winds for the remainder of the quarter. The overall construction progress at the end of September was 80.0% compared to 73.0% at the end of June. Plant construction progressed 9.6% during Q3 2022, bringing cumulative plant construction to 73.2%. The main power plant progressed to 75.3% and the main fuel station was completed as at 30 September. Pre-stripping at the Brecha Principal pit continued as planned and 7.3Mt was stripped during Q3 2022, bringing total volumes moved for the project to date to 50.0Mt. Pre-stripping was completed on 10 October 2022, slightly ahead of plan. The team remains focused on exploring the greater district, with US$3.5m on district exploration during the September quarter. A total of 12,172 metres were drilled during the first nine months of 2022, comfortably ahead of the planned 9,057 metres. South Deep outperforming expectations Gold Fields had a stable September 2022 quarter, with attributable gold equivalent production for Q3 2022 of 597koz, down 1% YoY (down 4% QoQ). South Deep in particular had another good quarter, with production up 2% QoQ. All-in cost (AIC) increased by 1% YoY (down 7% QoQ) to US$1,279/oz, while all-in sustaining costs (AISC) increased 4% YoY (and decreased 7% QoQ) to US$1,061/oz. AIC would have decreased by 6% QoQ to US$1,145/oz from US$1,220/oz if we exclude the significant project capex at Salares Norte. 597,000 ounces of attributable production US$1,061 per ounce of all-in sustaining cost US$1,279 per ounce of all-in cost JOHANNESBURG, 03 November 2022: Gold Fields Limited (NYSE & JSE: GFI) is pleased to provide an operational update for the quarter ended 30 September 2022. Detailed financial and operational results are provided on a six-monthly basis i.e. at the end of June and December.

Relocation of Chinchilla remains on hold until further notice from the authorities, however the team continues to monitor the two surviving Chinchilla that had already been relocated. As reported in August, first production is expected to be up to three months delayed. We anticipate being able to provide an update to production guidance at the end of the year. The original guidance is for first production at the end of March 2023 which will result in 200koz eq being produced in 2023. In the event that there is a one-month delay and first production is only achieved on 30 April 2023, Salares Norte will produce 165koz eq in 2023. If the delay is slightly longer and first gold is poured on 31 May, Salares Norte will produce 118koz eq in 2023 or at the end of June 2023, the mine will produce 102koz eq in 2023. Update on Yamana transaction We continue to make good progress on the transaction. The circular providing the full details of the transaction and incorporating the notice convening the Gold Fields General Meeting was posted to Gold Fields shareholders on Monday, 24 October 2022. The Gold Fields General Meeting is expected to be held on 22 November 2022. Gold Fields has also received approval of the Transaction from the Government of Canada pursuant to the Investment Canada Act. ESG updates Gold Fields tragically had a fatal incident at its St Ives mine in Western Australia on 11 October 2022, post the end of the reporting period. A raise bore operator working for one of our contractors at the Hamlet underground mine was dismantling the raise bore head when the incident occurred. The incident is being investigated by the regulator, police and an external specialist. This is the first fatality at any of our mines in Australia since Gold Fields started operating in the country in 2001. Our heartfelt condolences go out to the relatives, friends and colleagues of the deceased. During Q3 we recorded two serious injuries, bringing the total for the year-to-date to five. The Total Recordable Injury Frequency Rate (TRIFR) for the quarter improved to 1.72 injuries per million hours worked. Gold Fields continues to report significant progress in the rollout of renewable energy at its operations. In Australia, the US$20m, 12MW solar, 4.4MW battery plant at Gruyere became fully operational in August. The 50MW Khanyisa solar plant at South Deep was completed and fully commissioned in October, with the team optimising the electricity transmission to the mine. The plant has already achieved peak production of 47.5 MW and to date has generated 8.3 GWh of energy. FY 2022 guidance unchanged Given the solid operational performance year-to-date in 2022, we are on track to achieve the Group production guidance provided in February 2022. Mining cost inflation has been higher than initially expected, however, the weaker exchange rates (R/US$16.49 and US$/A$0.69) have partially offset the higher cost inflation. Consequently, we are leaving our cost guidance for the year unchanged. For 2022, attributable gold equivalent production (excluding Asanko) is expected to be between 2.25Moz and 2.29Moz (2021 comparable 2.25Moz). Including Asanko, attributable gold equivalent production is expected to be between 2.31Moz and 2.36Moz. AISC (excluding Asanko) is expected to be between US$1,140/oz and US$1,180/oz, with AIC (excluding Asanko) expected to be US$1,370/oz to US$1,410/oz. The exchange rates used for our 2022 guidance are: R/US$15.55 and US$/A$0.76. South Deep has been tracking well against its production targets throughout the year. As a result, the team has revised gold production guidance to 10,000kg (321,500ozs) for the year ending December 2022. Previous guidance was 9,600kg (308,600ozs) to 9,700kg (311,800ozs).

Underground mined reef grade increased by 6% to 6.41g/t in the September quarter from 6.05g/t in the June quarter as a result of; • Changes in the geology model (i.e -0.02g/t). • Volume blends (i.e +0.01g/t), and • Quality of mining of long hole stopes (i.e +0.28g/t). Underground reef yield increased by 10% to 6.98g/t in the September quarter from 6.32g/t in the June quarter due to higher underground reef grade mined, improved mine call factor, plant recoveries, and ore phasing. Total gold mined marginally decreased by 2% to 2,675kg (86,000oz) in the September quarter from 2,728kg (87,700oz) in the June quarter due to a decrease in ore mined volumes. Total development increased by 8% to 3,098 metres in the September quarter from 2,889 metres in the June quarter as a result of an increase in rig production rates, which is in line with the production plan. Secondary support installed decreased by 13% to 2,728 metres in the September quarter from 3,145 metres in the June quarter, due to intermittent support rig machine availability and the redeployment of rigs to conduct support rehabilitation. Backfill increased by 23% to 83,017m3 in the September quarter from 67,381m3 in the June quarter due to increase stope availability. Total underground tonnes milled decreased by 1% to 432kt in the September quarter from 437kt in the June quarter and surface tonnes milled decreased by 4% to 315kt in the September quarter from 327kt in the June quarter. All-in cost decreased by 8% at R649,812/kg (US$1,176/oz) in the September quarter from R705,902/kg (US$1,410/oz) in the June quarter due to lower cost of sales before amortisation and depreciation, lower capital expenditure and higher gold sold. Total capital expenditure decreased by 9% to R492m (US$29m) in the September quarter from R540m (US$35m) in the June quarter. Sustaining capital expenditure decreased by 7% to R423m (US$25m) in the September quarter from R455m (US$29m) in the June quarter mainly due to lower spend at the Doornpoort tailings facility and the solar plant as these projects near completion. Non-sustaining capital expenditure decreased by 20% to R69m (US$4m) in the September quarter from R86m (US$6m) in the June quarter due to lower spend on future ore handling infrastructure. The construction of the 50MW solar project is complete. The focus now is optimising the output of the plant by balancing the generated power to electrical demand. Supply of electricity from the plant commenced in August 2022 with a total of 8.3GWh of electricity been generated to date. Expenditure on the project to date is R647m (US$41m). The total expenditure is estimated to be R715m (US$45m).

Grade mined decreased by 7% to 5.88g/t in the September quarter from 6.31g/t in the June quarter due to increased volumes at lower grades mined from the Z100 area. As a result of the decrease in grade of ore mined, gold mined decreased by 7% to 75,500oz in the September quarter from 80,900oz in the June quarter. All-in cost increased by 7% to A$1,697/oz (US$1,157/oz) in the September quarter from A$1,585/oz (US$1,132/oz) in the June quarter due to a decrease in gold sold and increased capital expenditure, partially offset by decreased cost of sales before amortisation and depreciation. Capital expenditure increased by 26% to A$37m (US$25m) in the September quarter from A$29m (US$21m) in the June quarter. Sustaining capital expenditure increased by 52% to A$23m (US$16m) in the September quarter from A$15m (US$11m) in the June quarter due to increased capital development in the Z110 and Z120 areas as well as increased expenditure on a new tailings storage facility. Non-sustaining capital expenditure decreased by 1% to A$14m (US$10m) in the September quarter from A$14m (US$10m) in the June quarter due to timing of exploration expenditure.

For the September quarter, focus was on pre-stripping stage 4 of the Gruyere Pit, which resulted in a 20% increase in capital waste mined to 4.50Mt in the September quarter from 3.75Mt in the June quarter. As a result of the increased pre-stripping mined, ore mined decreased by 20% to 2.14Mt in the September quarter from 2.67Mt in the June quarter and operational waste mined decreased by 13% to 2.61Mt in the September quarter from 3.0Mt in the June quarter. As a result of the 20% decrease in ore mined, gold mined decreased by 21% to 81,500oz in the September quarter from 102,600oz in the June quarter. Tonnes milled decreased by 10% to 2.18Mt in the September quarter from 2.41Mt in the June quarter, due to the accelerated maintenance in the primary crusher and SAG mill liner wear components. All-in cost increased by 24% to A$1,521/oz (US$1,038/oz) in the September quarter from A$1,225/oz (US$874/oz) in the June quarter due to decreased gold sold and higher capital expenditure. Sustaining capital expenditure (on a 50% basis) increased by 48% to A$14m (US$10m) in the September quarter from $9m (US$7m) in the June quarter due to the pre-stripping of stage 4 of the Gruyere pit in the September quarter. 12 Gold Fields Operation update September Quarter 2022
