Gold Fields Limited Reg. No. 1968/004880/06) Incorporated in the Republic of South Africa) JSE, NYSE, DIFX Share Code: GFI ISIN Code:ZAE000018123 (Gold Fields or the Company) Operational update for the quarter ended 30 September 2024 - Attributable production 12% higher (QoQ) at 510koz - All-in sustaining costs (AISC) 3% lower (QoQ) at US$1,694/oz - All-in costs (AIC) 5% lower (QoQ) at US$1,909/oz JOHANNESBURG, 14 November 2024: Gold Fields Limited (NYSE & JSE: GFI) is pleased to provide an operational update for the quarter ended 30 September 2024. Detailed financial and operational results are provided on a six-monthly basis i.e. at the end of June and December. Statement by Mike Fraser, CEO Improved performance in Q3 Our operations achieved notable improvements in the quarter delivering a 12% increase in production to 510koz, and a 5% decrease in all-in cost (AIC) quarter on quarter (QoQ). At the start of the year, I highlighted five key priority areas for 2024 in line with the delivery of our strategy. As a reminder these were: - Ensuring the physical and psychological safety of our people. - Safe delivery against our production and cost targets. - Delivery of the Salares Norte ramp-up. - Continuing to improve the value and quality of our portfolio. - Continuing progress towards meeting our 2030 ESG targets. Below I provide an update on performance against these priorities. Ensuring the physical and psychological safety of our people The health, safety and wellbeing of our people remains our number one value and is core to everything that we do. As a leadership team, we believe that we can achieve a serious injury and fatality-free business, guaranteeing that everyone who works at Gold Fields goes home safe and well every day. Our safety trends for Q3 2024 were encouraging, with no serious injuries reported during the quarter. The total recordable injury frequency rate improved during Q3 to 2.26 per million hours worked from 3.14 in H1 2024. To maintain ongoing focus on safety, we continue to prioritise the actions underpinning our safety improvement roadmap, detailed below, with additional risk containment support being deployed in areas of higher risk across the business. Earlier this year, we undertook a review of the Group's safety culture, systems and practices, and identified a number of areas for improvement. The insights and expertise from employees and business partners were integral to this review, which now serves as the foundation of our safety improvement roadmap. This roadmap aims to bring about improvement to our safety performance through a multi-year Group-wide safety programme, which seeks to: - Develop and empower leaders across all levels to shift safety mindsets. - Improve our safety and risk systems to reduce risk and eliminate serious injuries and fatalities. - Partner with business partners on our safety guarantee through a standard business partner framework.

Fostering respectful workplaces is fundamental to our culture and is essential to delivering on our safety guarantee. We continue to make good progress in implementing the recommendations made in last year's Respectful Workplace independent across our business. Safe delivery against our production targets We recorded material improvement in our operating performance across the portfolio in the quarter under review, with notable increases in production delivered at Gruyere (+10% QoQ), Granny Smith (+16% QoQ), St Ives (+20% QoQ), South Deep (+23% QoQ), Tarkwa (+11% QoQ) and Cerro Corona (+14% QoQ). Group attributable gold-equivalent production for Q3 2024 was therefore 12% higher QoQ at 510koz (Q2 2024: 454koz), but 6% lower YoY (Q3 2023: 542koz). A further step-up is expected in Q4 2024, underpinned by continued improvements at Gruyere, St Ives, South Deep, Tarkwa and Cerro Corona, together with Salares Norte's first meaningful quarterly contribution. Group AIC for Q3 2024 decreased by 5% QoQ to US$1,909/oz (Q2 2024: US$2,008/oz) mainly due to the higher gold sold. It was, however, 18% higher YoY (Q3 2023: US$1,622/oz) due to lower gold sold compared to Q3 2023, coupled with higher capital expenditure. AISC for Q3 2024 of US$1,694/oz was 3% lower QoQ benefiting from higher gold production (Q2 2024: US$1,751/oz) but 23% higher YoY (Q3 2023: US$1,381/oz). Net debt decreased by US$30m to US$1,123m at the end of September 2024, mainly due to strong cash generation which was partially offset by payment of the interim dividend of US$152m (June 2024: US$153m). We remain in a strong financial position with a net debt to EBITDA of 0.47x at the end of Q3 2024, compared to 0.53x in Q2 2024. Post the quarter-end we paid US$1.39bn (C$1.93bn), net of cash received, in full and final settlement of the Osisko Mining Inc (Osisko) acquisition which was completed on 25 October 2024. This was paid from cash on hand, undrawn debt facilities and liquidity facilities totalling US$750m that were executed in October 2024. Update on South Deep: Operational improvements in Q3 South Deep gold production increased by 23% (411kg) to 2,229kg (71.7koz) in Q3 2024 with higher production underpinned by improved stope availability (following positive progress made with backfill rehandling) and improved long hole stope drilling. Access to and turnaround of stopes was therefore markedly improved in the quarter. The mine made significant progress in rehandling backfill material. Backfill leakage was also reduced and in Q3 was less than 1% of total backfill volumes placed. Reef grade improved by 15% from 5.53g/t to 6.34g/t, as the mine gained access to previous destress areas and with the opening of the mining footprint. Delivery of the Salares Norte ramp-up Ramp-up of Salares Norte recommenced slightly ahead of the planned plant restart date of 30 September 2024 and the mine produced 198oz- eq during Q3 2024. The quarter under review was focused on unfreezing and purging remaining material in the primary circuits Installation of by-pass circuits early in the winter ensured that the main components of the plant could continue to run and circulate solution while the main circuit was being cleaned. Despite experiencing a late snow event in early October 2024, ramp-up has continued according to plan and is expected to proceed into H1 2025, with commercial levels of production set to be achieved in Q2 2025. Steady state throughput on a monthly basis is expected in Q4 2025. Guidance for Salares Norte remains unchanged for 2024 at 40koz-eq - 50koz-eq. 2025 gold-equivalent production is expected to be between 325koz-eq - 375koz-eq at AISC of US$975/oz-eq - US$1,125/oz-eq, depending on the ramp-up progress. 2026 is anticipated to be the first full year of steady-state production.

The capture and relocation of the Chinchillas was put on hold in Q3 2024, in line with our plan to halt activities during the winter months. The urgent and transitional measure (MUT) issued by Chile's Superintendence of Environment (SMA) ordering the suspension of dismantling activities at Rockery Area No 3, located at the North waste dump of the mine, expired on 3 October 2024. During the quarter, we had constructive engagement with the SMA, following which we have implemented several improvements to our planned processes. Capture and relocation activities are scheduled to recommence at Rockery Area No 3 in November 2024. Suspension of the capture and relocation programme during the winter period has had no impact on the current operations or future plans for Salares Norte's production. Continuing to improve the value and quality of our portfolio Acquisition of Osisko, consolidating 100% ownership in Windfall, a quality, multi-decade asset On 12 August, Gold Fields announced an all-cash offer to acquire 100% of the outstanding shares of Osisko. Gold Fields paid C$1.93bn (US$1.39bn) net of cash received, in settlement of the transaction. The transaction was finalised on 25 October 2024, following receipt of all regulatory approvals and approval by 99.5% of the Osisko shareholders voting at a special shareholder meeting held on 17 October 2024. The transaction consolidates Gold Fields' 50% stake into full ownership and control of the Windfall Project and its entire exploration district (c.2,500km(2)) in Québec, Canada. It also eliminates our existing obligation of a C$300m deferred cash payment and a C$75m exploration commitment, which formed part of the original JV agreement. Current focus for the project is obtaining the required environmental permitting for full scale construction and undertaking the engineering work required to take the project to our Board for a final investment decision. Construction will commence following Board approval and is expected to take approximately 18 to 24 months. We will provide a more definitive timeline for the project in the new year. Key members of the current Windfall team have remained with the project and we are currently working to integrate the team into Gold Fields. Engagements for the execution of an Impact Benefit Agreement with the Cree First Nation of Waswanipi and the Cree Nation Government are also ongoing. Update on the Tarkwa/Iduapriem JV in Ghana As per our joint announcement released on SENS on 7 November 2024, notwithstanding constructive engagement with the Government of Ghana since the announcement of the proposed joint venture on 16 March 2023, the requisite approvals by the Government for the JV have not yet been obtained. Gold Fields and AngloGold Ashanti have sought to secure these approvals ahead of the October 2024 parliamentary recess before the Ghana national elections set for December 2024. Both companies continue to believe that a combination of these two neighbouring mines into a single managed entity is compelling, given that it is anticipated to extend life-of-mine, increase production and lower costs, thereby creating value for all stakeholders. In the absence of the requisite approvals from the Government of Ghana and clear timelines for execution of an agreement, Gold Fields and AngloGold Ashanti will maintain engagement in relation to a potential asset combination while separately continuing to pursue improvements to their respective assets. Continuing progress towards our 2030 ESG targets We are progressing our commitment to decarbonise our mines and reduce energy costs. During the quarter, construction continued on the St Ives Renewables Project, which we expect to be operational in 2026. Once completed it is expected to deliver over 70% of the mine's electricity requirements and reduce the mine's electricity costs to a third of previously projected 2026 costs. Construction of the renewable project has been slightly delayed resulting in some of the capital planned for 2024 being pushed into 2025. As such, capital spend on the project during 2024 will be lower than originally planned.

During the quarter we also commenced with expansion of our solar farm at Granny Smith. Upon completion, scheduled for early 2025, the mine will have a total of 19MW of solar capacity - an increase of 11MW - as well as additional 7MW capacity through a battery energy storage system. The expansion will enable up to 21% of the mine's energy requirements to be generated through renewable energy sources. Subsequent to the quarter-end, on 11 October 2024, the environmental impact assessment for in-pit tailings deposition at our Cerro Corona mine was approved by the relevant authorities. The approval effectively extends the mine's expected life to 2031. Mining activities at the mine will continue at current levels until the end of 2025, after which the mine will process stockpiled ore until 2031. In August, the Gold Fields Ghana Foundation handed over the newly constructed and refurbished Tarkwa & Abosso (T&A) Stadium in Tarkwa, to the country's National Sports Authority. Rehabilitation work on the T&A Stadium started in January 2020 and was completed this year at a total cost of US$16.2m. This significant investment has transformed the 400-seat football park into an 8,000-plus seater world-class stadium, which is capable of hosting international matches and will be home to Medeama SC, a Ghana Premier League team. The stadium is also expected to boost business activities, nurture young talent, and facilitate the development of football in the region, including women's football. Leadership appointments In August, we announced the appointment of Phil Murnane as Gold Fields' Chief Financial Officer and an executive director of the Company. We are currently finalising Phil's commencement date. Alex Dall will continue as Interim CFO and will work with Phil to ensure a smooth transition. At the beginning of September, Chris Gratias joined us as EVP Strategy & Corporate Development. Prior to joining Gold Fields, Chris was Global Head of Mining at Canadian investment bank CIBC. The appointments of Shannon McCrae and Zarina Bassa as non- executive directors to the Company's Board, announced with our H1 2024 results, took effect on 1 August 2024. Zarina also joined the Audit Committee of the Board. 2024 guidance unchanged We expect a further step up in production in Q4 2024 and are keeping Group FY2024 guidance unchanged from that released with our interim results in August. This is underpinned by increased production at all our operations, with St Ives set to record the largest QoQ increase in Q4 as the Swiftsure and Invincible Footwall South open pits start contributing meaningfully. Group attributable gold-equivalent production for 2024 is expected to be at the lower end of our guidance of 2.05Moz - 2.15Moz, with AISC of between US$1,580/oz - US$1,670/oz and AIC of between US$1,820/oz - US$1,910/oz. This implies H2 2024 attributable gold-equivalent production of between 1.11Moz - 1.21Moz. H2 2024 unit costs are expected be lower than those reported for H1 2024, with AISC forecast between US$1,460/oz - US$1,580/oz and AIC set to be between US$1,630/oz - US$1,750/oz for H2 2024.

In the quarter under review, production improved considerably, with total tonnes mined increasing by 38% to 14.2Mt compared to 10.3Mt in the June quarter. Gold production was consequently 10% higher at 68,800oz in the September quarter up from 62,500oz in the June quarter due to increased ore processed. Gold production is expected to increase further in Q4 2024. Despite the higher gold produced, AIC increased by 7% to A$2,915/oz (US$1,949/oz) in the September quarter from A$2,707/oz (US$1,784/oz) in the June quarter mainly due to increased capital expenditure as pre-stripping of Stages 4 and 5 of the Gruyere pit continued. Total capital expenditure (on a 50% basis) was 48% higher at A$43m (US$28m) in the September quarter compared to A$29m(US$19m) in the June quarter. The focus remains on pre-stripping at Stages 4 and 5 of the Gruyere pit in line with the revised mine plan to catch up on the shortfall in pre-strip mining following the rainfall event.

As previously reported, Cerro Corona, experienced inclement weather in Q1 2024 affecting the stability of the North wall of the pit, resulting in a resequencing of mining to lower grade areas. Stability of the North wall was addressed during the June quarter with mining at Cerro Corona expected to continue to recover in Q4 2024. AIC per gold ounce sold decreased by 25% to US$502/oz in the September quarter from US$672/oz in the June quarter, mainly due to a higher gold inventory credit to cost due to higher concentrate stock at the end of September compared to June. Total capital expenditure increased by 4% to US$5m in the September quarter from US$5m in the June quarter, driven by the TSF Water Treatment Plant construction plan and TSF Coronation Channel construction.
