Media Release STATEMENT BY CHRIS GRIFFITH, CEO SALIENT FEATURES Reviewed Results I Six months ended 30 June 2022 Strong operational performance and cash generation in H1 2022 The operating environment during H1 2022 was dominated by elevated mining cost inflation driven by rising commodity and fuel prices. Despite these challenges, Gold Fields had a strong H1 2022, with production increasing 9% YoY and all-in costs rising only 6% YoY. As a result of the increased production combined with a 3% higher gold price, the company increased its normalised earnings by 16% YoY and generated strong free cash flow of US$293m. This enabled us to declare an interim dividend of 300 SA cents per share and further reduce our net debt by almost US$120m from the end of FY 2021. The proposed acquisition of Yamana, announced at the end of May 2022, was the key focus during H1 2022. We maintain the view that the acquisition of Yamana represents the best option to accelerate Gold Fields’ growth strategy and deliver long term shareholder value. Having explored both organic growth and bolt-on acquisitions, moving to completion stage of the transaction is the best opportunity to accelerate the next phase of the company’s growth in value. H1 2022 in review The Group has not had a fatal injury since April 2021. Regrettably, three serious injuries were recorded for the six-month period compared with four serious injuries in H1 2021. Attributable gold equivalent production for H1  2022 was 1,201koz, a 9% increase YoY (H1  2021: 1,104koz). AIC for H1 2022 was US$1,352/oz, 6% higher than H1 2021 (US$1,274/oz), as a result of an increase in operating costs driven by mining inflation and the increased project capex at Salares Norte. AISC for H1 2022 was US$1,148/oz (H1 2021: US$1,093/oz), a 5% increase YoY. Normalised earnings for the six months ended June 2022 increased by 16% YoY to US$498m, or US$0.56 per share, compared to US$431m, or US$0.49 per share, for H1 2021. In line with our dividend policy of paying out between 25% and 35% of normalised profit as  dividends, we have declared an interim dividend at the upper end of the payout ratio of 300 SA cents per share, which compared with the 2021 interim dividend of 210 SA cents per share. This represents a 43% increase YoY. US$293m adjusted free cash flow* +63% US$518m adjusted free cash flow from operations +31% US$498m normalised earnings +16% 1.201m ounces of attributable production +9% US$1,148 per ounce of all-in sustaining cost +5% US$1,352 per ounce of all-in cost +6% * Cash flow from operating activities less net capital expenditure, environmental payments, lease payments and redemption of Asanko preference shares. JOHANNESBURG, 25 August 2022: Gold Fields Limited (NYSE & JSE: GFI) announced profit attributable to owners of the parent for the six months ended 30 June 2022 of US$510m (US$0.57 per share). This compared with profit of US$387m (US$0.44 per share) for the six months ended 30 June 2021. An interim dividend of 300 SA cents per share (gross) is payable on 19 September 2022. Strong cash generation and further improved balance sheet During H1 2022, Gold Fields, generated adjusted free cash flow of US$293m (after taking into account all costs in the business and all project capex), which compares to the adjusted free cash flow of US$180m in H1 2021. Looking at the core operations, the Group generated adjusted free cash flow from operations of US$518m in H1 2022, which compares to US$399m in H1 2021. There was a further improvement in the balance sheet during H1 2022. The net debt balance at the end of June 2022 was US$851m and our net debt to EBITDA ratio was 0.33x. This compares with a net debt balance of US$969m and a net debt to EBITDA ratio of 0.40x at the end of December 2021. Excluding lease liabilities, the core net debt was US$451m at the end of H1 2022.

Covid-19 update The impact of the Covid-19 pandemic abated even further in H1 2022, especially in Q2, as governments relaxed restrictions and requirements for testing, movements and gatherings. By mid- August 2022, 87% of our 22,000 strong workforce was fully vaccinated. Since the beginning of the pandemic, Gold Fields has undertaken almost 280,000 tests and to date we have had 7,800 Covid-19 positive cases, while, sadly, 20 employees and contractors have passed away from Covid-related illnesses, though none so far in 2022. The one region where there has been an impact on operations is Chile where the 4th wave of Covid-19 has had an effect on Salares Norte’s program. Spending on Covid-related programmes and projects totalled approximately US$12m in H1 2022. ESG developments Gold Fields continues to work on implementing programmes to achieve its ambitious 2030 ESG targets for its six key priority areas. Work is progressing well, particularly in decarbonising our operations. Electricity supply to our Cerro Corona mine in Peru was certified 100% renewable during April, while the R715m, 50MW solar plant at South Deep is set for commissioning during Q3 2022. In Australia, the US$20m, 12MW solar – 4.4MW battery plant at Gruyere was fully operational this month (August), while public consultations on the renewables microgrid for St Ives commenced in July. Regional performance The Australian region had a solid Q2 2022, producing 269koz at AIC of  A$1,657/oz (US$1,183/oz) and AISC of A$1,508/oz (US$1,076/oz) and  bringing production for H1 2022 to 527koz at AIC of A$1,685/oz (US$1,211/oz). Our mines in Ghana produced 215koz (including 45% of Asanko) during Q2 2022 at AIC of US$1,246/oz and AISC of US$1,213/oz. For the  six  months ended 30 June, Ghana produced 424koz at AIC of US$1,230/oz. Cerro Corona produced 74koz (gold equivalent) at AIC of US$957 per gold equivalent ounce and AISC of US$921 per gold equivalent ounce during the June quarter, resulting in 130koz (gold equivalent) being produced in the first half at AIC of US$981 per gold equivalent ounce. South Deep continued its strong momentum into Q2 2022, producing 86koz at AIC of R705,902/kg (US$1,410/oz) and AISC of R673,899/kg (US$1,347/oz). This resulted in H1 2022 production of 164koz at AIC of ZAR705,623/kg (US$1,425/oz). Update on Salares Norte Total project progressed from 62% at the end of 2021 to 77.0% at the end of H1 2022. Construction progressed 9.3% during the June quarter, bringing the overall construction progress at the end of June to 73.1%. Plant construction progressed 14.9% during Q2 2022, bringing cumulative plant construction to 63.6%. Construction activities at Salares Norte were impacted by Covid and severe weather conditions during the latter part of Q2 2022. US$94.2m was spent on the project during the quarter. A total of US$172m was spent on the project during the six months ended 30 June 2022. Pre-stripping at the Brecha Principal pit continued as planned and 9.0Mt was stripped during Q2 2022, bringing the total volumes moved for H1 2022 to 19.8Mt. Total volumes moved for the project to date stand at 42.7Mt, slightly ahead of plan. The team remains focused on exploring the greater district, with US$15m on district exploration during H1 2022. A total of 11,103 metres were drilled during the first six  months of 2022, comfortably ahead of the planned 9,057 metres. 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. After managing to keep the project on track through the challenges of the past two years – Covid and elevated mining inflation – severe weather events during recent months have resulted in marginal delays in the project timeline. While work is being done to clawback the recent lost time, we estimate up to a three-month delay to the commencement of production. Consequently, there may be a knock-on impact on the ramp up to full production. Given the uncertainty around the actual extent of the delay (0-3 months) as well as the mitigation actions, we anticipate being able to provide an update to production guidance at the end of the year. The current 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 on 15 June 2023, the mine will produce 102koz eq in 2023. As guided in our Q1 operating update, we expect the project capex to be 5-7% higher than original guidance of US$860m real (US$920m nominal) which would have resulted in capex spend of US$920m – in line with the US$920m nominal number. Given the potential delay, capex could be in the range of US$920m-US$940m. Proposed acquisition of Yamana On 31 May 2022, Gold Fields and Yamana Gold Inc. announced that they have entered into a definitive agreement, under which Gold Fields will acquire all of the outstanding common shares of Yamana, pursuant to a plan of arrangement. Under the terms of the Transaction, all of the outstanding Yamana shares will be exchanged at a ratio of 0.6 of an ordinary share in Gold Fields or 0.6 of a Gold Fields American depositary share for each Yamana share. The transaction is subject to the approval by both Gold Fields’ and Yamana’s shareholders. At this stage, we expect the shareholder meetings to take place end October/early November 2022, with a potential closing of the transaction by mid November 2022. The transaction is also subject to, among other conditions precedent, the approval by the Ontario Superior Court of Justice (Commercial List), applicable regulatory approvals. At the end of July 2022, Gold Fields received approval by the South African Reserve Bank for the proposed acquisition of Yamana. FY 2022 guidance unchanged Given the solid operational performance in H1 2022, we are on track to achieve the Group production guidance provided in February 2022. Mining inflation has been higher than initially expected, however, the higher-than-expected copper by-production credit and weaker exchange rates (R/US$15.84 and US$/A$0.70) has 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. 2022 Effective mining inflation forecast Forecast inflation as at February 2022 Forecast inflation as at April 2022 Forecast Inflation as at July 2022 Australia 9.4% 10.2% 11.9% Ghana 10.9% 12.2% 11.5% Peru 6.8% 10.5% 13.1% South Africa 11.2% 8.6% 8.3% Chile 2.7% 8.9% 8.4% Group 9.9% 10.5% 10.9% Chris Griffith Chief Executive Officer 25 August 2022 2 Gold Fields H1 Results 2022

Six months ended 30 June 2022 (H1 2022) compared with the six months ended 30 June 2021 (H1 2021) Results for the Group Safety and Health The Group has not had a fatal injury since April 2021. Regrettably, 3 serious injuries were recorded for the six months ended 30 June 2022, though this was lower than the four injuries reported in the same period in 2021. Pleasingly the injury severity rate continues to decline. The Total Recordable Injury Frequency Rate (TRIFR) for the Group regressed to 2.36 for the six months ended 30 June 2022 from 1.85 for H1 2021 mainly attributed to the high turnover and lower skill level of new recruits in Australia. Six months ended Safety H1 22 H1 21 FY21 Fatalities 0 1 1 TRIFR1 2.36 1.85 2.16 Serious injuries5 3 4 9 1 TRIFR = (Fatalities + Lost Time Injuries2 + Restricted Work Injuries3 + Medically Treated Injuries4) x 1,000,000/number of hours worked. 2 A Lost Time Injury (LTI) is a work-related injury resulting in the employee or contractor being unable to attend work for a period of one or more days after the day of the injury. The employee or contractor is unable to perform any functions. 3 A Restricted Work Injury (RWI) is a work-related injury sustained by an employee or contractor which results in the employee or contractor being unable to perform one or more of their routine functions for a full working day, from the day after the injury occurred. The employee or contractor can still perform some of his duties. 4 A Medically Treated Injury (MTI) is a work-related injury sustained by an employee or contractor which does not incapacitate that employee and who, after having received medical treatment, is deemed fit to immediately resume his/her normal duties on the next calendar day, immediately following the treatment/re-treatment. 5 A Serious Injury is a work-related injury that incurs 14 days or more of work lost and results in a range of injuries detailed at goldfields.com/safety.php Environmental No Level 3 – 5 environmental incidents were reported for the six months ended 30 June 2022, continuing the trend of preceding years. Fresh water withdrawal dropped by 6% to 4.7 gigalitres (GL) for the six  months ended 30  June  2022, mainly due to a decrease in water withdrawal at Tarkwa as the operation improved its water recycling and reuse. Water recycled/reused was 75% of total water use for the six months ended 30  June  2022 compared with 74% in H1 2021. This is because Tarkwa installed a micro-filtration unit on a clarifier return line to the carbon-in-leach plant as well as optimized recycling/reuse at Cerro Corona during the dry season. Group energy spend was US$206m (21% of operating costs) for the six  months ended 30  June  2022 compared with US$150m (17%) in H1  2021, reflecting increased production, higher diesel prices and the inclusion of leasing costs in 2022. For the six months ended 30 June 2022, energy savings of 480 terajoules (TJ) were achieved (6% of H1 energy consumption), compared with 642 TJ (8% of energy consumption) for H1 2021. Scope 1 and 2 CO₂ emissions were 864kt for the six  months ended 30 June 2022 compared with 841kt during H1 2021, as a result of a rise in tonnes mined over the period. CO₂ emissions intensity increased slightly to 8.6kg CO₂e/t mined from 8.5kg CO₂e/t in H1 2021. Renewable energy in H1 2022 accounted for 12% of our total electricity, with renewables providing 50% of electricity consumed by our Agnew mine in Australia and the electricity supply to our Cerro Corona mine in  Peru was certified 100% renewable. The R715m, 50MW solar plant at South Deep and the USD20m, 12MW solar – 4.4MW battery plant at Gruyere are scheduled for completion in Q3 2022. The Salares Norte Chinchilla Rescue and Relocation Plan remains suspended, pending review by the Authority of the revised Compliance Programme. The relocation delay is not expected to delay construction of the project. Gold Fields published its fourth Climate Change Report for the 2021 financial year in line with the recommendations of the Taskforce on Climate-related Financial Disclosures (TCFD).

The Group’s value distribution to national economies was US$1.9bn for the six  months ended 30  June  2022 compared with US$1.9bn for H1 2021, Gold Fields procurement from in- country suppliers was US$1.1bn for the six months ended 30 June 2022 (97% of total procurement) compared with US$1.1bn for H1 2021 (97% of total). Gold Fields aims to sustain the value delivered to host communities through employment, procurement and social investments. The Group host community workforce was 9,342 people – 53% of the total workforce (excluding projects and corporate offices) for the six  months ended 30 June 2022 compared with 9,200, 52% of the total workforce, for H1 2021. Group host community procurement spend for the six  months ended 30 June 2022 was US$358m (30% of total spend), compared with US$339m (31% of total) during H1 2021. Spending on socio-economic development (SED) projects in our host communities totalled US$9.2m for the six months ended 30 June 2022 compared with US$7.1m for H1 2021. Our total workforce at the end of June was 22,294 (including projects and corporate offices), comprising 6,251 employees and 16,043 contractors compared with a total workforce of 22,110 at year-end 2021.

H1 Operating Performance Managed equivalent gold production (including 45% share of Asanko) increased by 8% from 1,148,200oz for the six months ended 30 June 2021 to 1,245,300oz for the six  months ended 30  June  2022. Attributable equivalent gold production, (including Asanko) increased by 9% from 1,104,100oz for the six months ended 30 June 2021 to 1,200,500oz for the six months ended 30 June 2022. At the South Africa region, attributable gold production (96.4%) at South Deep increased by 28% from 3,828kg (123,100oz) for the six months ended 30  June  2021 to 4,915kg (158,000oz) for the six  months ended 30  June 2022. Managed gold sold increased by 32% from 3,868kg (124,400oz) to 5,097kg (163,900oz). Attributable gold production (90%) at the West African operations (including 45% of Asanko), decreased by 4% from 401,000oz for the six months ended 30 June 2021 to 385,800oz for the six months ended 30 June 2022 mainly due to planned decreased production at Damang and Asanko. Managed gold produced and sold at Tarkwa increased marginally from 256,900oz for the six  months ended 30  June  2021 to 257,300oz for the six months ended 30 June 2022. At Damang, managed gold produced and sold decreased by 6% from 133,500oz for the six months ended 30 June 2021 to 125,200oz for the six months ended 30 June 2022 mainly due to lower yield as a result of low-grade material fed from the stockpile to augment the ex-pit material combined with a 1% drop in plant recovery when comparing to H1 2021. Attributable gold produced at Asanko decreased by 16% from 49,700oz for the six months ended 30 June 2021 to 41,600oz for the six months ended 30 June 2022 due to lower grade ore processed. Gold sold at Asanko decreased by 24% from 52,300oz (45%) to 39,700oz (45%). Attributable equivalent gold production (99.5%) at Cerro Corona in Peru increased by 31% from 98,800oz for the six months ended 30 June 2021 to 129,300oz for the six months ended 30 June 2022 mainly due to higher grades of ore processed and higher recoveries. In H1 2021 production was also impacted by a revised mining sequence due to slope instability at the high-grade eastern side of the pit. Total managed gold equivalent production increased by 31% from 99,300oz for the six  months ended 30 June 2021 to 129,900oz for the six months ended 30 June 2022. Gold equivalent ounces sold increased by 26% from 103,500oz to 130,500oz. Gold production at the Australian (100%) operations increased by 10% from 481,200oz for the six months ended 30 June 2021 to 527,400oz for the six months ended 30 June 2022 mainly due to higher grades of ore mined and processed at Agnew, Granny Smith and Gruyere as well as improved mill performance at Gruyere. At St Ives, gold production increased by 1% from 188,500oz for the six months ended 30 June 2021 to 190,300oz for the six months ended 30 June 2022. Gold sold increased by 2% from 188,500oz to 191,700oz. At Agnew, gold production increased by 8% from 111,700oz for the six months ended 30 June 2021 to 120,500oz for the six months ended 30 June 2022 due to an increase in grade of ore mined and processed in line with the plan, partially offset by a decrease in ore milled. The higher-grade ore was mainly sourced from the Kath lode orebody at Waroonga. Gold sold increased by 8% from 112,500oz to 121,000oz. At Granny Smith, gold production increased by 14% from 121,300oz for the six months ended 30 June 2021 to 138,300oz for the six months ended 30 June 2022 due to increased grade of ore mined at the Z120 mining area and increased grade of ore processed, partially offset by a decrease in ore milled. Gold sold increased by 13% from 122,600oz to 138,300oz. At Gruyere gold production (50% basis) increased by 31% from 59,700oz for the six months ended 30 June 2021 to 78,400oz for the six months ended 30 June 2022 due to higher grades of ore mined from Stages 2 and 3 of the Gruyere pit combined with higher grade of ore processed. Tonnes processed increased by 11% in H1 2022 when compared to H1 2021 with the processing improvement projects yielding the desired results. Gold sold increased by 31% from 60,600oz to 79,600oz. COVID-19 report The impact of the COVID-19 pandemic abated in the first half of 2022, especially in Q2, as governments relaxed restrictions and requirements for testing, movement, gatherings and masks. Having recorded no cases before February 2022, our Australia region experienced high numbers of cases, albeit mild, this did have some impact on production. We also saw the start of a 4th wave of Covid-19 in Chile in Q2 which did have some impact on contractor staff availability and Salares Norte construction. One person was hospitalized briefly during the quarter, in sharp contrast to the situation in H1 2021, when at least two employees were in hospital at any time. The diminished effect of the pandemic on the company may be attributed to a combination of the milder omicron variant, vaccination programmes across the Group, strict adherence to all government regulations/ protocols, rigorous implementation of risk-related work practices and social media awareness and return-to-work communication campaigns for employees, communities and others. By late July 2022, 88% of our total workforce was fully vaccinated, with the Americas and Australia regions and our corporate offices staff 100% fully vaccinated. 52% of our workforce had received at least one booster shot, again with the Americas and Australia regions at or close to 100%. 38% of our Americas workforce had received a second booster. Since the beginning of the pandemic, Gold Fields has undertaken almost 280,000 tests among its 22,000 strong workforce. To date we have had 7,800 COVID-19 positive cases among employees and contractors. Regrettably, 20 employees and contractors have passed away, the last in H2 2021. Spending on COVID-19 related programmes and projects totalled US$12m during H1 2022. Gold Fields H1 Results 2022 7

The average Rand gold price increased by 11% from R838,127/kg to R926,383/kg. The average Australian Dollar gold price increased by 11% from A$2,340/oz to A$2,600/oz. The average US Dollar gold price for the Ghanaian operations (excluding Asanko) increased by 4% from US$1,801/oz for the six months ended 30 June 2021 to US$1,881/oz for the six months ended 30 June 2022. The average equivalent US Dollar gold price, net of treatment and refining charges, for Cerro Corona decreased by 6% from US$1,772/eq oz for the six months ended 30 June 2021 to US$1,668/eq oz for the six months ended 30 June 2022. The average US  Dollar/Rand exchange rate weakened by 6% from R14.54 for the six  months ended 30  June  2021 to R15.40 for the six  months ended 30 June 2022. The average Australian/US Dollar exchange rate weakened by 6% from A$1.00 = US$0.77 to A$1.00 = US$0.72. Gold equivalent ounces sold (excluding Asanko) increased by 10% from 1.10Moz to 1.21Moz. Revenue from Asanko is not included in Group revenue as Asanko results are Equity-accounted. Revenue increased by 13% from US$1,984m for the six  months ended 30 June 2021 to US$2,235m for the six months ended 30 June 2022 due to the 10% higher gold sold and 3% higher gold price received. Cost of sales before amortisation and depreciation Cost of sales before amortisation and depreciation increased by 11% from US$832m for the six months ended 30 June 2021 to US$923m for the six months ended 30 June 2022 mainly due to inflationary increases of US$130m affecting all the regions partially offset by a US$39m impact of the weakening of the Australian Dollar and South African Rand. At the South Africa region, at South Deep, cost of sales before amortisation and depreciation increased by 19% from R2,150m (US$148m) for the six months ended 30 June 2021 to R2,558m (US$166m) for the six months ended 30  June  2022. Limiting the increase in cost of sales before amortisation and depreciation to 19% demonstrates good cost control considering a 28% increase in production combined with inflationary cost pressures. At the West Africa region, (excluding Asanko), cost of sales before amortisation and depreciation increased by 9% from US$233m for the six months ended 30 June 2021 to US$254m for the six months ended 30 June 2022 mainly due to increased prices on items such as diesel and explosives increasing the mining unit costs. These increases are on the back of the abnormal global inflation pressures seen at present. At the South America region, at Cerro Corona, cost of sales before amortisation and depreciation increased by 2% from US$91m for the six months ended 30 June 2021 to US$93m for the six months ended 30 June 2022. At the Australia region, cost of sales before amortisation and depreciation increased by 22% from A$466m (US$360m) for the six  months ended 30  June  2021 to A$569m (US$409m) for the six  months ended 30 June 2022. This increase is mainly due to a 10% increase in production and an increase in ore tonnes and operational waste tonnes mined at the Gruyere pit. The costs in the Australian region were also negatively impacted by abnormally high pressures on commodity inputs and employee costs which included retention payments in order to contain the abnormally high employee turnover in Australia during the six months ended 30 June 2022. Amortisation and depreciation Amortisation and depreciation for the Group increased by 20% from US$315m for the six months ended 30 June 2021 to US$378m for the six  months ended 30  June  2022 mainly due to a US$75m increase related to higher production partially offset by a US$12m impact of the weakening of the Australian Dollar and South African Rand. Investment Income Investment income remained similar at US$4m. Finance expense Finance expense for the Group increased by 6% from US$36m for the six months ended 30 June 2021 to US$38m for the six months ended 30  June  2022 due to an allocation of lease and rehabilitation interest partially offset by lower borrowings and higher interest capitalised during the six months ended 30 June 2022. Interest expense on borrowings of US$38m, interest lease liability of US$11m and rehabilitation interest of US$6m partially offset by interest capitalised of US$17m for the six months ended 30 June 2022 compared with interest expense on borrowings of US$41m, partially offset by interest capitalised of US$5m for the six months ended 30 June 2021. Share of results of Equity-accounted investees after taxation The share of results of Equity-accounted investees after taxation of a loss of US$5m for the six  months ended 30  June  2022 compared to an income of US$17m for the six months ended 30 June 2021. The decrease is as a result of lower profitability at Asanko for the six  months ended 30 June 2022. Gain/(loss) on foreign exchange The gain on foreign exchange of US$16m for the six  months ended 30 June 2022 compared with a loss on foreign exchange of US$7m for the six  months ended 30  June  2021 and related to the conversion of offshore cash holdings into their functional currencies. Gain/(loss) on financial instruments The gain on financial instruments of US$23m for the six months ended 30 June 2022 compared with a loss of US$53m for the six months ended 30 June 2021.

Long-term incentive plan The long-term incentive plan decreased by 8% from US$12m for the six  months ended 30  June  2021 to US$11m for the six  months ended 30 June 2022 due to the current marked-to-market valuation of the plan reflecting forecast performance. Other costs, net Other costs for the Group decreased by 66% from US$32m for the six  months ended 30  June  2021 to US$11m for the six  months ended 30  June  2022 and mainly related to the reallocation of lease interest and rehabilitation interest to the interest line in 2022. 8 Gold Fields H1 Results 2022

The cash balance at 30 June 2022 of US$724m compared with US$704m at 30 June 2021. Adjusted free cash flow Adjusted free cash flow increased by 63% from US$180m for the six months ended 30 June 2021 to US$293m for the six months ended 30  June  2022 due to higher cash flows from operating activities and lower dividends, partially offset by higher capital expenditure. The US$293m adjusted free cash flow for the six  months ended 30 June 2022 comprised: US$518m free cash generated by the eight mining operations (after royalties, taxes, capital expenditure and environmental payments) less US$172m spend at Salares Norte (comprising US$145m in capex, US$15m in exploration, a US$6m investment in working capital and other costs of US$8m, partially offset by a credit of US$2m from the realised portion of the FX hedge) less US$32m of net non-mine interest paid as well as US$21m on non-mine based costs mainly due to working capital movements. The US$180m adjusted free cash flow for the six  months ended 30 June 2021 comprised: US$399m free cash generated by the eight mining operations (after royalties, taxes, capital expenditure and environmental payments) less US$149m spend at Salares Norte (comprising US$133m in capex, US$13m in exploration, a US$12m investment in working capital, a tax payment of US$9m and other costs of US$5m, partially offset by a credit of US$23m from the realised portion of the FX hedge) plus redemption of Asanko preference shares of US$5m, less US$33m of net non-mine interest paid as well as US$42m on non-mine based costs mainly due to working capital movements. Statement of financial position Net debt decreased by 12% from US$969m at 31 December 2021 to US$851m at 30 June 2022. Net debt excluding lease liabilities decreased by 18% from US$553m at 31 December 2021 to US$451m at 30 June 2022. Net debt is defined by the Group as total borrowings and lease liabilities less cash and cash equivalents. Net debt/adjusted EBITDA The net debt/adjusted EBITDA ratio of 0.33 at 30 June 2022 compared with 0.49 at 30 June 2021. The net debt/adjusted EBITDA ratio of 0.33 at 30 June 2022 is based on net debt of US$851m and adjusted EBITDA of US$2,590m. The net debt/adjusted EBITDA ratio of 0.49 at 30 June 2021 is based on net debt of US$1,097m and adjusted EBITDA of US$2,225m. 10 Gold Fields H1 Results 2022

Adjusted EBITDA Adjusted EBITDA for calculating net debt/adjusted EBITDA is based on the profit for the 12 months ended 30 June 2022 and is determined as follows in US$ million: US$’m June 2022 Revenue 4,447 Cost of sales before amortisation and depreciation (1,753) Exploration and project costs (60) Other costs* (44) 2,590 * Other costs include other non-mine based costs and hedge losses. Adjusted EBITDA is defined by the Group as profit or loss for the year adjusted for interest, taxation, amortisation and depreciation and certain other non-operating costs. US$’m June 2021 Revenue 4,121 Cost of sales before amortisation and depreciation (1,553) Exploration and project costs (47) Other costs* (296) 2,225 * Other costs relate mostly to the hedge losses for the year. Adjusted EBITDA is defined by the Group as profit or loss for the year adjusted for interest, taxation, amortisation and depreciation and certain other non-operating costs. All-in sustaining and total all-in cost The Group all-in sustaining costs increased by 5% from US$1,093/oz for the six months ended 30 June 2021 to US$1,148/oz for the six months ended 30 June 2022 mainly due to higher sustaining capital expenditure and higher cost of sales before amortisation and depreciation, partially offset by higher gold sold. If the all-in sustaining costs are normalised for  the weakening of the currencies by using the same exchange rates as  in the first six  months of 2021, the all-in sustaining costs would be US$1,196/oz for the six months ended 30 June 2022. This represents a 9% increase in all-in sustaining costs compared with the six months ended 30 June 2021. Total all-in cost increased by 6% from US$1,274/oz for the six months ended 30  June  2021 to US$1,352/oz for the six  months ended 30  June  2022 mainly due to higher sustaining and non-sustaining capital expenditure and higher cost of sales before amortisation and depreciation, partially offset by higher gold sold. The higher non-sustaining capital expenditure was mainly at Salares Norte which increased from US$133m for the six months ended 30 June 2021 to US$145m for the six months ended 30 June 2022 in line with the project progress. Normalising for the exchange rate differences, the total all-in cost would be US$1,404/oz for the six months ended 30 June 2022, a 10% increase when compared with the six months ended 30 June 2021.

Ore mined increased by 9% to 815,600t for the six months ended 30 June 2022 from 745,200t for the six months ended 30 June 2021 and gold produced increased by 28% to 5,097kg (163,900oz) for the six  months ended 30  June  2022 from 3,970kg (127,600oz) for the six months ended 30 June 2021. These increases are a result of higher underground ore and grade mined, which is in line with the Business plan and production ramp-up. Development increased by 21% to 5,705 metres for the six months ended 30 June 2022 from 4,723 metres for the six months ended 30 June 2021 as a result of an increase in rig productivity rates, which is in line with the production plan. Waste mined increased by 13% to 98,800t for the six  months ended 30 June 2022 from 87,300t for the six months ended 30 June 2021 as a result of an increase in capital infrastructure development and Cut-5 access development in the North of wrench mining area. Secondary support increased by 10% to 7,051 metres for the six months ended 30  June  2022 from 6,382 metres for the six  months ended 30 June 2021 in line with the increase in development metres and stoping volumes. Backfill increased by 27% to 153,800m3 for six months ended 30 June 2022 from 120,800m3 for the six months ended 30 June 2021 as a result of improved stope availability. Underground reef yield increased by 27% to 6.59g/t for the six months ended 30 June 2022 from 5.20g/t for the six months ended 30 June 2021 due to mining higher grade reefs in line with the mine plan. All-in cost increased by 5% to R705.623/kg (US$1,425/oz) for the six months ended 30 June 2022 from R674,965/kg (US$1,444/oz) for the six months ended 30 June 2021 mainly due to higher cost of sales before amortisation and depreciation (inflation and higher production levels), and higher capital expenditure, partially offset by higher gold sold. Capital expenditure increased by 128% to R978m (US$64m) for the six months ended 30 June 2022 from R428m (US$30m) for the six months ended 30 June 2021 as explained below. Sustaining capital expenditure increased by 180% to R811m (US$53m) for the six  months ended 30  June  2022 from R290m (US$20m) for the six  months ended 30  June  2021 mainly due to inflationary increases, equipment deliveries, Doornpoort tailings facility expansion and the commencement of the building of the solar plant. Non-sustaining capital expenditure increased by 21% to R167m (US$11m) for the six months ended 30  June  2022 from R138m (US$10m) for the six  months ended 30 June 2021. This increase was mainly due to the advancement of the development on 100L and 105L with associated infrastructure. South Deep generated adjusted free cash flow of R1,131m (US$74m) for the six months ended 30 June 2022 compared with an inflow of R407m (US$28m) for the six months ended 30 June 2021. The increase is mainly due to 32% increase in gold sold and a higher realised gold price received, partially offset by higher cost of sales before amortisation and depreciation as well as higher capital expenditure. Guidance 2022 Guidance for 2022 provided in February remains unchanged as follows: • Gold produced ~ 9,600kg (308,600oz) to 9,700kg (311,800oz); • Capital expenditure ~ R1,930m (US$124m); • All-in sustaining costs ~ R715,000/kg (US$1,430/oz); and • Total all-in cost ~ R755,000/kg (US$1,510/oz). 12 Gold Fields H1 Results 2022

Total tonnes mined, including capital waste stripping, decreased by 7% to 43.4Mt for the six  months ended 30  June  2022 from 46.4Mt for the six months ended 30 June 2021 in line with the 2022 production schedule. Ore tonnes mined increased by 22% to 6.3Mt for the six months ended 30 June 2022 from 5.2Mt for the six months ended 30 June 2021. Capital waste tonnes mined decreased by 21% to 22.3Mt for the six  months ended 30 June 2022 from 28.2Mt for the six months ended 30 June 2021 due to focus on ore and operational waste mining. Operational waste mined, increased by 13% to 14.7Mt for the six months ended 30 June 2022 from 13.0Mt for the six months ended 30 June 2021. Strip ratio decreased by 28% to 5.8 for the six months ended 30 June 2022 from 8.0 for the six months ended 30 June 2021 due to increased ore mined in line with the 2022 production schedule. All-in cost increased by 9% to US$1,306/oz for the six  months ended 30 June 2022 from US$1,203/oz for the six months ended 30 June 2021 due to higher royalty tax, on the back of higher gold prices, higher mining cost as a result of an increase in fuel and explosives price and higher capital expenditure as a result of increased activities and inflation. Capital expenditure increased by 12% to US$120m for the six  months ended 30  June  2022 from US$108m for the six  months ended 30 June 2021 due to higher capital waste expenditure as a result of higher mining unit rates. Tarkwa generated adjusted cash flow of US$104m for the six  months ended 30 June 2022 compared with US$115m for the six months ended 30 June 2021 mainly due to higher capital expenditure and higher costs partially offset by a higher gold price received. Guidance 2022 Inflationary increases in fuel and explosive prices and increases in royalty tax as a result of the higher forecasted gold price resulted in a revision of Tarkwa’s guidance as follows: • Gold produced ~ 515,000oz (unchanged); • Capital expenditure ~ US$228 (original guidance US$198m); • All-in sustaining costs ~ US$1,340/oz, (original guidance US$1,230/oz); and • Total all-in cost ~ US$1,340/oz, (original guidance US$1,230/oz).

A total of 294kt ore was rehandled from the stockpile for the six months ended 30 June 2022 at a grade of 1.32g/t compared with 421kt at a grade of 1.96g/t for the six months ended 30  June  2021. In addition, plant recovery decreased to 92% for the six months ended 30 June 2022 compared with the 93% for the six months ended 30 June 2021 on the back of the lower grade. Total tonnes mined increased by 6% to 12.6Mt for the six months ended 30 June 2022 from 11.8Mt for the six months ended 30 June 2021 due the to inclusion of Huni pit mining. Operational waste tonnes decreased by 39% to 4.6Mt for the six months ended 30 June 2022 from 7.5Mt for the six months ended 30 June 2021 in line with the plan. Ore tonnes mined decreased by 16% to 3.6Mt for the six months ended 30 June 2022 from 4.3Mt for the six months ended 30 June 2021. Gold mined decreased by 16% to 182,600oz for the six  months ended 30 June 2022 from 216,400oz for the six months ended 30 June 2021 due to lower ore tonnes mined. Strip ratio increased by 39% to 2.5 for the six months ended 30 June 2022 from 1.8 for the six  months ended 30  June  2021 due to the increased capital waste stripping in the Huni pit. All-in cost increased by 19% to US$964/oz for the six  months ended 30 June 2022 from US$810/oz for the six months ended 30 June 2021 due to lower gold sold and higher capital expenditure due to the Huni waste stripping, partially offset by lower cost of sales before amortisation and depreciation. Capital expenditure increased by 225% to US$33m for the six  months ended 30 June 2022 from US$10m for the six months ended 30 June 2021. Sustaining capital expenditure increased by 373% to US$28m for the six months ended 30 June 2022 from US$6m for the six months ended 30 June 2021 due to expenditure on Huni waste stripping. Non-sustaining capital expenditure increased by 21% to US$5m for the six months ended 30 June 2022 from US$4m for the six months ended 30 June 2021 due to Stage 4 design and Zone C rockfill placement of the FETSF. Damang generated adjusted free cash flow of US$50m for the six months ended 30 June 2022 compared with US$67m for the six months ended 30 June 2021 mainly due to the decrease in gold sold, and higher costs and capital. Guidance 2022 Damang gold production remains unchanged. However, increases in fuel and explosive prices, rise and fall indices and other inflationary pressures have impacted on the year’s AIC. In addition to the above, royalty has also increased due to the higher forecasted gold price. Damang’s guidance is therefore revised as follows: • Gold produced ~ 229,000oz (unchanged); • Capital expenditure ~ US$58m (original guidance US$52m); • All-in sustaining costs ~ US$1,020/oz (original guidance US$950/oz), and • Total all-in cost ~ US$1,100/oz (original guidance US$1,030/oz), Asanko (Equity-accounted Joint Venture) All figures in table on a 100% basis June 2022 June 2021 % Variance Ore mined 000 tonnes 1,750 3,174 (45)% Waste (capital) 000 tonnes — 1,479 (100)% Waste (operational) 000 tonnes 6,599 17,146 (62)% Total waste mined 000 tonnes 6,599 18,625 (65)% Total tonnes mined 000 tonnes 8,349 21,799 (62)% Grade mined g/t 1.53 1.27 20% Gold mined 000’oz 86.0 129.5 (34)% Strip ratio waste/ ore 3.8 5.9 (36)% Tonnes milled 000 tonnes 2,888 2,919 (1)% Yield g/t 0.99 1.18 (16)% Gold produced 000’oz 92.4 110.4 (16)% Gold sold 000’oz 88.2 116.3 (24)% AISC US$/oz 1,482 1,314 13% AIC US$/oz 1,576 1,448 9% Sustaining capital expenditure US$m 4.1 10.6 (61)% Non-sustaining expenditure US$m 1.9 10.2 (81)% Total capital expenditure US$m 6.0 20.8 (71)% Redemption of preference shares US$m — 5.0 (100)% Gold production decreased by 16% to 92,400oz (100% basis) for the six  months ended 30  June  2022 from 110,400oz (100% basis) for the six months ended 30 June 2021 mainly due to lower tonnes milled and lower yield. The decrease in gold production is in line with the guidance provided in Q1 of ramping down in mining activities at Esaase and Akwasiso Cut 3. Mining activities at the Esaase pit was ended in May 2022. Total tonnes mined decreased by 62% to 8.3Mt for the six months ended 30 June 2022 from 21.8Mt for the six months ended 30 June 2021. Waste tonnes mined decreased by 65% to 6.6Mt for the six  months ended 30 June 2022 from 18.6Mt for the six months ended 30 June 2021 mainly due to lower stripping of Akwasiso Cut 3 and suspension of mining activities at Esaase in May 2022. Similarly, ore tonnes mined decreased by 45% to 1.8Mt for the six  months ended 30  June 2022 from 3.2Mt tonnes for the six months ended 30 June 2021. All-in cost increased by 9% to US$1,576/oz for the six  months ended 30 June 2022 from US$1,448/oz for the six months ended 30 June 2021 underpinned by a 24% decrease in gold sales, partially offset by lower capital expenditure. Total capital expenditure (100% basis) decreased by 71% to US$6m for the six months ended 30 June 2022 from US$21m for the six months ended 30 June 2021. Sustaining capital expenditure decreased by 61% to US$4m for the six months ended 30 June 2022 from US$11m for the six months ended 30 June 2021. Non-sustaining capital expenditure decreased by 81% to US$2m for the six months ended 30 June 2022 from US$10m for the six months ended 30 June 2021. The decreases in capital expenditure are in line with the ramping down of activities with most of the big capital items from 2021 (TSF raise, Tetrem RAP etc.) not recurring in 2022. Most of the exploration capital expenditure in 2022 are scheduled to occur in the second half of the year. Full year gold production guidance (100% basis), is estimated at between 135Koz-145Koz (original guidance – 110Koz-130Koz). 14 Gold Fields H1 Results 2022

In both cases, the increases were mainly due to higher yield as a result of higher head grades processed and higher recoveries. As a result of the above, equivalent gold production (100% basis) increased by 31% to 129,900oz for the six months ended 30 June 2022 from 99,300oz for the six months ended 30 June 2021. Total tonnes mined decreased by 2% to 13.2Mt for the six months ended 30 June 2022 from 13.5Mt for the six months ended 30 June 2021 mainly due to a decrease in waste mined by 27% to 7.7Mt for the six  months ended 30 June 2022 from 10.5Mt for the six months ended 30 June 2021, partially offset by an increase in ore mined of 81% to 5.5Mt for the six months ended 30 June 2022 from 3.0Mt for the six months ended 30 June 2021. All-in cost per gold ounce increased by 24% to US$397/oz for the six  months ended 30  June  2022 from US$321/oz for the six  months ended 30 June 2021 mainly due to higher operating expenses as a result of the worldwide inflation related to commodities such as diesel, grinding media, explosives and energy among others; partially offset by higher gold ounces sold and lower capital expenditure. All-in cost per equivalent ounce decreased by 16% to US$981/eq oz for the six  months ended 30 June 2022 from US$1,162/eq oz for the six months ended 30 June 2021 mainly due to higher equivalent ounces sold and lower capital expenses, partially offset by higher operating expenses as described above. Total capital expenditure decreased by 13% to US$16m for the six months ended 30 June 2022 from US$19m for the six months ended 30 June 2021. Non-sustaining capital expenditure decreased by 66% to US$4m for the six months ended 30 June 2022 from US$12m for the six months ended 30 June 2021 mainly due to the Arpon waste storage facility construction (US$8m) included in the capital for H1 2021 in order to comply with the mining sequence. Sustaining capital expenditure increased by 75% to US$12m for the six  months ended 30  June  2022 from US$7m for the six  months ended 30  June  2021 due to the focus on the construction activities at the tailings dam during H1 2022 and land acquisition expense. Cerro Corona generated adjusted free cash flow of US$56m for the six  months ended 30  June  2022 compared with US$28m for the six months ended 30 June 2021 mainly due to the increase in gold and copper production and higher gold and copper prices. Guidance 2022 As a result of the inflationary increases guidance for 2022 provided in February revised as follows: • Gold equivalents produced ~ 255,000oz (unchanged); • Gold produced ~ 120,000oz (unchanged); • Copper tonnes produced ~ 27,000t (unchanged); • Capital expenditure ~ US$46m (unchanged); • Copper price ~ US$8,000 per tonne (unchanged); • Gold price ~ US$1,600/oz (unchanged); • All-in sustaining costs ~ US$970/eq oz (original guidance US$900/eq oz); • Total all-in cost ~ US$1,050/eq oz (original guidance US$990/eq oz); • All-in sustaining costs ~ US$320/oz(unchanged); and • Total all-in cost ~ US$500/oz (unchanged). In line with the planned mining sequence used to determine the 2022 guidance, equivalent gold production is expected to decrease in Q3  2022, with full year production still in line with guidance provided in February 2022. Chile Salares Norte Salares Norte total project progress is now at 77% and construction progress increased to 73.1% for the six months ended 30 June 2022. The total project to date of 77% compares with 41.9% at the end of June 2021 and 62.5% at the end of December 2021. During the latter part of Q2 and the start of Q3 2022 a fourth wave of Covid-19 and severe weather conditions have impacted the construction activities at Salares Norte. After managing to keep the project on track through the challenges of the past two years i.e Covid-19, staff shortages, elevated mining inflation and severe weather events, the recent wave of Covid-19 and weather events is likely to have a marginal delay of 1-3 months on the project timeline. Consequently there may be a knock- on impact on the ramp up to full production. Given the uncertainty around the actual extent of the delay (0-3 months) as well as the mitigation actions, we anticipate being able to provide an update on production guidance for 2023/2024 at the end of the year.

US$172m was spent on the project for the six months ended 30 June 2022 compared with US$149m spent for the six months ended 30 June 2021. The US$172m spent comprised of US$145m capital expenditure, US$15m exploration, a US$6m investment in working capital, US$8m in other cost, partially offset by a credit of US$2m from the realised portion of the currency hedge. The US$149m spent during the six  months ended 30  June  2021 comprised of US$133m capital expenditure, US$13m exploration, a US$12m investment in working capital, a tax payment of US$9m and other cost of US$5m, partially offset by a credit of US$23m from the realised portion of the currency hedge. Pre-stripping at the Brecha Principal pit continues as planned and 19.8Mt was stripped for the six  months ended 30  June  2022 compared with 6.1Mt  stripped for the six  months ended 30  June  2021. Project to date pre-stripping is 42.7Mt. The exploration team remains focused on exploring the district, with 11,103 metres drilled for the six months ended 30 June 2022 compared with 12,470 metres drilled for the six months ended 30 June 2021. In our Q1 operating update, we guided that we are unlikely to deliver the project at the US$860m real capital number. Previously, we anticipated that due to very few change of  scope variations and limited use of contingency we were targeting to deliver the project at US$860m nominal and in Q1 we guided that a 5-7% higher capex spend was likely i.e close to the US$920m nominal (US$860m real). If any delays into Q2 2023 occur the capital projection is likely to be US$920m – US$940m.

At the underground operations, ore mined decreased by 16% to 801kt for the six months ended 30 June 2022 from 958kt for the six months ended 30  June  2021 as the Invincible mine develops into higher volume extension vein stopes and due to increasing paste fill requirements as the second Invincible paste plant comes online. Gold mined decreased by 13% to 130,000oz for the six months ended 30 June 2022 from 149,200oz for the six months ended 30 June 2021, as a result of the decrease in ore mined, partially offset by a 4% increase in grade mined. 16 Gold Fields H1 Results 2022

In the open pits, total tonnes mined increased by 78% to 7,285kt for the six months ended 30 June 2022 from 4,088kt for the six months ended 30 June 2021. This reflected a push to strip stage 7 of the Neptune pit. The mix of tonnes mined was heavily weighted to pre-strip with ore mined decreasing by 69% to 201kt for the six months ended 30 June 2022 from 646kt for the six months ended 30 June 2021. Strip ratios will return to more normal levels in the second half of 2022 as production moves toward mining ore and operating waste. Grade mined in the open pits decreased by 60% to 1.08g/t for the six months ended 30 June 2022 from 2.71g/t for the six months ended 30 June 2021 when ore mining occurred in the higher grade stages 5 and 6 of the Neptune pit. Tonnes milled of 2,041kt for the six months ended 30 June 2022 included approximately 1,000kt drawn from stockpiles compared to approximately 450kt drawn from stockpiles for the six months ended 30 June 2021. All-in cost increased by 23% to A$1,715/oz (US$1,233/oz) for the six months ended 30 June 2022 from A$1,398/oz (US$1,078/oz) for the six months ended 30 June 2021 due to high level of pre-strip with minimal ounces being derived from the open pits. All-in cost per ounce will decrease in the second half of 2022 as the open pits move back to a normal production profile. All-in cost for the six months ended 30 June 2022 was also impacted by the abnormally high inflationary pressures on commodity inputs and employee costs. Total capital expenditure increased by 24% to A$83m (US$59m) for the six months ended 30 June 2022 from A$66m (US$51m) for the six months ended 30 June 2021.

Grade mined increased by 11% to 7.38g/t for the six  months ended 30 June 2022 from 6.64g/t for the six months ended 30 June 2021 due to increased grade of ore mined from Waroonga with ore production from the high grade Kath lode ore body. As a result of the increase in grade partially offset by a 2% decrease in ore mined, gold mined increased by 9% to 121,000oz for the six months ended 30 June 2022 from 111,400oz in the six months ended 30 June 2021. All-in cost increased by 11% to A$1,882/oz (US$1,353/oz) for the six months ended 30 June 2022 from A$1,692/oz (US$1,305/oz) for the six months ended 30 June 2021 due to increased capital expenditure and inflationary pressures on commodity inputs and employee costs, which resulted in higher production costs. The production and capital cost increases were partially offset by increased gold sold. Total capital expenditure increased by 25% to A$69m (US$49m) for the six months ended 30 June 2022 from A$55m (US$42m) for the six months ended 30 June 2021.

Ore tonnes mined increased by 17% to 5.3Mt for the six months ended 30 June 2022 from 4.6Mt for the six months ended 30 June 2021 with increased ore sourced from stage 3 of the Gruyere pit. Capital waste tonnes mined decreased by 23% to 10.50Mt for the six months ended 30 June 2022 from 13.6Mt for the six months ended 30 June 2021 and operational waste tonnes mined increased by 2109% to  3.8Mt for the six  months ended 30  June  2022 from 0.2Mt for the six  months ended 30  June  2021 following stage 3 of the Gruyere pit moving out of pre-strip phase during 2022.

As a result of the increase in grade and a 17% increase in ore mined, gold mined increased by 39% to 193,900oz for the six  months ended 30 June 2022 from 139,900oz for the six months ended 30 June 2021. 18 Gold Fields H1 Results 2022

Ore tonnes milled increased by 11% to 4.5Mt for the six months ended 30 June 2022 from 4.1Mt for the six months ended 30 June 2021 with processing improvements projects yielding record production rates. All-in cost decreased by 9% to A$1,348/oz (US$969/oz) for the six months ended 30 June 2022 from A$1,486/oz (US$1,146/oz) for the six months ended 30  June  2021 due to higher gold sold and decreased capital expenditure, partially offset by higher production cost resulting from inflationary pressures on commodity inputs and employee costs. Capital expenditure (on a 50% basis) decreased by 22% to A$22m (US$16m) for the six months ended 30 June 2022 from A$28m (US$22m) for the six  months ended 30  June  2021, reflecting the completion of pre-stripping stage 3 of the pit. Gruyere generated adjusted pre-tax free cash flow (on a 50% basis) of A$87m (US$62m) for the six months ended 30 June 2022 compared with A$37m (US$28m) for the six months ended 30 June 2021, mainly due to increased gold sold and a higher gold price received from A$2,345/oz (US$1,811/oz) for the six  months ended 30  June  2021 to A$2,609/oz (US$1,876/oz) for the six months ended 30 June 2022. Guidance 2022 The impact of higher production costs has made it necessary to update the original guidance of Gruyere to the following: • Gold produced ~ 165,000oz (50%), (original guidance 145,000oz (50%) to 165,000oz (50%)); • Capital expenditure ~ A$51m (US$36m) (original guidance A$45m (US$34m)) (50%); • All-in sustaining costs ~ A$1,400/oz (US$985/oz), (original guidance A$1,245/oz (US$945/oz); and • Total all-in cost ~ A$1,410/oz (US$990/oz), original guidance A$1,265/oz (US$960/oz). Corporate 2021 Climate change report published Gold Fields Limited published its Climate Change Report 2021 (CCR), which is part of its integrated annual reporting suite. The CCR is the Company’s fourth report aligned to the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD). The CCR provides an extensive overview of the climate change-related risks we are facing, how we seek to mitigate these risks, the opportunities we are investigating and our climate change performance to date. It also provides an insight into our decarbonisation strategy, which headlines one of the three pillars of Gold Fields’ new strategy, namely “Building on our leading commitment to environmental, social and governance issues”. The decarbonisation targets, announced last year, are to reduce Scope 1 and 2 carbon emissions by 30% by 2030. As we plan to raise our production profile over the same period, this translates to a 50% emission reduction in real terms. We are also committed to net-zero carbon emission by 2050. The CCR describes the steps we plan to take to meet the targets. Renewable energy and energy efficiency projects at our mines will account for about two-thirds of these reductions by 2030 and have already delivered 18% emission reductions against business as usual between 2016 and 2021. Renewables currently account for about 12.5% of the Group’s electricity mix, due to the two completed renewable micro-grids at Granny Smith and Agnew in Western Australia as well as the contribution of our Cerro  Corona mine, which derives all its electricity from hydropower. Cerro Corona’s supply was certified as renewable in March this year. With new solar plants coming on stream at Gruyere in Western Australia and South Deep in South Africa this year, at Salares Norte in Chile in 2024 as well as an extensive renewables-led microgrid at St Ives in Western Australia, also in 2024, we expect that renewables will account for about 22% of the Group’s electricity mix by 2025. Gold Fields is also committed to reviewing its Scope 3 emissions over the next few years and will develop Scope 3 emission reduction targets in its decarbonisation strategy by 2023. The CCR also includes the outcomes of our second, five-yearly climate change risks and vulnerability assessment at all our mines and their surrounding communities. The surveys outline the adverse impacts of rising temperatures, increased rainfall, longer droughts, more intense storms, and other effects of the changing climate on our operations and stakeholders. S&P Global Ratings upgrades Gold Fields credit rating S&P Global Ratings upgraded Gold Fields’ credit rating to ‘BBB-’ from ‘BB+’ as well as the debt ratings on the Group's senior unsecured notes. S&P also raised the short-term rating on the Group to ‘A-3’ from ‘B’ and affirmed its 'zaAAA/zaA-1+' South African national scale ratings. Gold Fields provides comprehensive ESG information update In May 2022, Gold Fields provided comprehensive environmental, social and governance (ESG) information via a number of released reports and presentations. These address the increased data and information expectations of our stakeholders, including our shareholders, and reflects the company’s commitment to transparent disclosure of its ESG performance, opportunities and risks. The disclosures focus on Gold Fields’ six key ESG priorities – decarbonisation; tailings management; water stewardship; safety, health, well-being and environment; diversity; and stakeholder value creation. 2030 targets and accompanying strategies and programmes for each of these priorities were announced by the company in December last year.

Gold Field’s proposed acquisition of Yamana Gold – a combination for long-term value creation focused on quality growth, financial discipline and shareholder returns • Transaction creates a top-4 global gold major with a diversified portfolio of high-quality, long-life assets with tangible near and long-term growth opportunities. • Strengthened financial and operational capacity with complementary cash flow and growth profiles. • Combined Group will be headquartered in Johannesburg with operations across South Africa, Ghana, Australia, Canada and South America. • All-share offer by Gold Fields at an Exchange Ratio of 0.6 Gold Fields Consideration Shares for each Yamana share implying a valuation for Yamana of US$6.7bn. On 31 May 2022 Gold Fields and Yamana Gold Inc. (Yamana), announced that they have entered into a definitive agreement (the “Arrangement Agreement”), under which Gold Fields will acquire all of the outstanding common shares of Yamana (Yamana Shares) pursuant to a plan of arrangement (the Transaction). Under the terms of the Transaction, all of the outstanding Yamana Shares will be exchanged at a ratio of 0.6 of an ordinary share in Gold Fields (each whole share, a “Gold Fields Share”) or 0.6 of a Gold Fields American depositary share (each whole American depositary share, a Gold Fields ADSs) for each Yamana Share (the Exchange Ratio). The Transaction implies a valuation for Yamana of US$6.7bn and represents a premium of 33.8% to the 10-day Volume-Weighted Average Price (VWAP) of Yamana’s Shares of US$5.201 on Friday, May 27, 2022, being the last trading day on the NYSE prior to the date of this announcement, based on the 10-day VWAP of Gold Fields ADSs of US$11.592. Upon closing of the Transaction, it is anticipated that Gold Fields Shareholders and Yamana Shareholders will own approximately 61% and 39% of the Combined Group, respectively. The acquisition of Yamana by Gold Fields significantly strengthens the ability of the combined company (the Combined Group) to deliver on Gold Fields’ three strategic pillars: maximizing asset potential; advancing ESG commitment; and growing the value and quality of its asset portfolio. The Combined Group has the potential to create significant long-term value for shareholders through greater scale, an industry-leading portfolio of assets, an enhanced production profile with significant growth potential, operational and geological synergies, and a strengthened financial profile for future growth and shareholder returns. Gold Fields’ Board believes that offering the Gold Fields Consideration Shares is the best way to capture and unlock growth opportunities while still maintaining financial flexibility, capital and operational discipline, and providing attractive returns to shareholders. Strong near-term operating cash flows from Gold Fields’ producing assets complement the manageable capital requirements of Yamana’s world class, high return project portfolio, providing greater capacity to fund the combined growth pipeline internally, while maintaining shareholder returns in line with Gold Fields’ existing policy. Yamana is a natural strategic fit for Gold Fields, with its high quality, diversified portfolio of long life assets located in mining friendly rules- based jurisdictions across the Americas (including its five producing mines and pipeline of development projects and exploration properties) and with a shared focus on health and safety and ESG performance. With the combination of Gold Fields’ and Yamana’s portfolio of assets, Gold Fields will become a new global gold major able to create value at every stage of its pipeline. The Combined Group will maintain its presence in all regions while continuing to honour commitments to stakeholders. Gold Fields believes that this Transaction offers employees and communities more opportunities in the long-term given its track record of ongoing investment in the regions in which it operates. The Transaction has been unanimously approved by the Board of Directors of both Gold Fields and Yamana and is expected to close in the second half of 2022 subject to and following the satisfaction of the conditions precedent to the Transaction. The acquisition will be implemented by way of a plan of arrangement of Yamana under the Canada Business Corporations Act pursuant to the Arrangement Agreement entered into between Gold Fields and Yamana dated 31 May 2022. The consideration payable to the shareholders of Yamana will consist of either, at the election of a Yamana shareholder, newly issued Gold Fields Shares or newly issued Gold Fields ADSs, which each represent one Gold Fields Share, in accordance with the Exchange Ratio. The Gold Fields Shares are listed on the Johannesburg Stock Exchange and the Gold Fields ADSs are listed on the NYSE. If shareholders approve the Transaction, our intention is to obtain a secondary listing on the Toronto Stock Exchange.

Outlook for 2022 Given the solid operational performance in H1 2022, we are on track to achieve the Group production guidance provided in February 2022. Mining inflation has been higher than initially expected, however, the higher-than-expected copper by-production credit and weaker exchange rates (R/US$15.84 and US$/A$0.70) has partially offset the higher cost inflation. Consequently, we leave 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. Total capex for the Group for the year is expected to be between US$1.050bn and US$1.150bn. Sustaining capital is expected to be between US$625m and US$675m, with non-sustaining capex expected to be between US$425m and US$475m. The largest component of the capex budget for the year is Salares Norte project capital, with US$330m expected to be spent. The above is subject to safety performance which limits the impact of safety-related stoppages and the forward-looking statement on pages 5 and 59. Gold Fields H1 Results 2022 21

Basis of preparation The condensed consolidated interim financial statements for the six months ended 30 June 2022 have been prepared in accordance with International Financial Reporting Standard (IFRS), IAS 34 ‘Interim Financial Reporting’, the SAICA Financial Reporting Guides as issued by the Accounting Practices Committee and Financial Pronouncements as issued by the Financial Reporting Standards Council and the requirements of the South African Companies Act of South Africa 71 of 2008 (Companies Act), as amended, and the JSE Limited Listings Requirements. The condensed consolidated financial statements are prepared on a going concern basis. The condensed consolidated financial statements are presented in United States Dollars, which is Gold Fields Limited’s presentation currency. The accounting policies applied in the preparation of these condensed consolidated financial statements are in terms of International Financial Reporting Standards and are consistent with those applied in the previous annual financial statements. Pro forma financial information The preliminary financial statements contain certain non-IFRS financial measures in respect of the Group’s financial performance, the statement of financial position and cash flows presented in order to provide users with relevant information and measures used by the Group to assess performance. These measures constitute pro forma financial information in terms of the JSE Limited Listings Requirements and are the responsibility of the Group’s Board of Directors. They are presented for illustrative purposes only and due to their nature, may not fairly present Gold Fields’ financial position, changes in equity, results of operations or cash flows. The key non-IFRS measures used and defined in the media release include: • Normalised profit attributable to owners of the parent which is defined as profit excluding gains and losses on foreign exchange, financial instruments and non-recurring items after taxation and non-controlling interest effect; • Normalised profit per share attributable to owners of the parent; • Net debt which is calculated as borrowings plus the current portion of borrowings and lease liabilities plus current portion of lease liabilities less cash and cash equivalents; • Net debt (excluding lease liabilities) which is calculated as borrowings plus the current portion of borrowings less cash and cash equivalents; • Adjusted free cash flow is calculated as cash flow from operating activities less net capital expenditure, environmental payments, lease payments and redemption of Asanko preference shares; • Adjusted free cash flow from operations is calculated as cash flow from operating activities less net capital expenditure, environmental payments and lease payments from the eight mining operations; • Adjusted EBITDA is required to be determined in terms of loan and revolving credit facilities agreements to evaluate compliance with debt covenants; • Sustaining capital expenditure represents the majority of capital expenditures at existing operations, including mine development costs, ongoing replacement of mine equipment and other capital facilities and other capital expenditures at existing operations; • Non-sustaining capital expenditure represents capital expenditures for major growth projects as well as enhancement capital for significant infrastructure improvements at existing operations; and • All-in sustaining costs and total all-in cost are presented to provide transparency into the costs associated with producing and selling an ounce of gold and is a common measure presented within the mining industry. This pro forma financial information has not been reported on by the Group’s auditors, being PricewaterhouseCoopers Inc. Auditor’s review The condensed consolidated financial statements of Gold Fields Limited for the six month period ended 30 June 2022 have been reviewed by the Company’s auditor, PricewaterhouseCoopers Inc. The auditor’s report does not necessarily report on all of the information contained in this media release. Shareholders are therefore advised that in order to obtain a full understanding of the nature of the auditor’s engagement they should refer to page 57 of the media release for a copy of the auditor’s report. Class action settlement The Tshiamiso Trust has been established to carry out the terms of the class action settlement agreement reached between six gold mining companies (including Gold Fields) and claimant attorneys in the silicosis and TB class action. The Tshiamiso Trust is responsible for ensuring that all eligible current and former mineworkers across southern Africa with silicosis or work-related TB (or their dependants where the mineworker has passed away) are compensated pursuant to the silicosis and TB class action settlement agreement and Tshiamiso Trust Deed (collectively the “Settlement Agreement”). Financial provision Gold Fields has provided for the estimated cost of the class action settlement based on actuarial assessments and the provisions of the Settlement Agreement. At 30 June 2022, the provision for Gold Fields’ share of the settlement of the class action claims and related costs amounts to US$13.0m (R211.7m) (December 2021: US$13.1m (R209.6m)). The nominal value of this provision is US$16.2m (R263.9m). The ultimate outcome of this matter however remains uncertain, with the number of  eligible workers successfully submitting claims and receiving compensation being uncertain. The provision is consequently subject to adjustment in the future. Segment reporting The net profit (excluding Asanko) per the income statement reconciles to the net profit in the segmental operating and financial results as follows: Six months ended 30 June 2022 US$’m Net profit 533.6 – Operating segments 583.3 – Corporate and projects (49.7)* Six months ended 30 June 2021 US$’m Net profit 410.1 – Operating segments 481.0 – Corporate and projects (70.9)* * Comprises mainly of non-mine interest and other costs.

During the periods ended 30 June 2022 and 2021, the Gold Fields Limited 2012 Share Plan as amended in 2016 was in place. At the Annual General Meeting on 18 May 2016, shareholders approved the adoption of the revised Gold Fields Limited 2012 Share Plan to replace the long-term incentive scheme ("LTIP"). The plan provides for four types of participation, namely Performance Shares ("PS"), Retention Shares ("RS"), Restricted Shares ("RSS") and Matching Shares ("MS"). This plan is in place to attract, retain, motivate and reward participating employees on a basis which seeks to align the interests of such employees with those of the Company’s shareholders. 2 Senior and middle management receive awards under the LTIP. The performance conditions of the LTIP are approved annually by the Remuneration Committee. The expected timing of the cash outflows in respect of each grant is at the end of three years after the original award was made. 3 Included under "Other costs, net" in the consolidated income statement. 4 Lease interest of US$11.3m and environmental rehabilitation interest adjustments of US$6.0m for the six months ended 30 June 2022 were included in net interest expense. Refer note 4. 5 The Mineral and Petroleum Resource Royalty Act 2008 (“Royalty Act”) was promulgated on 24 November 2008 and became effective from 1 March 2010. The Royalty Act imposes a royalty on refined (mineral resources that have undergone a comprehensive level of beneficiation such as smelting and refining as defined in Schedule 1 of the Act) and unrefined (mineral resources that have undergone limited beneficiation as defined in Schedule 2 of the Act) minerals payable to the state. The royalty in respect of refined minerals (which include gold refined to 99.5% and above and platinum) is calculated by dividing earnings before interest and taxes (“EBIT”) by the product of 12.5 times gross revenue calculated as a percentage, plus an additional 0.5%. EBIT refers to taxable mining income (with certain exceptions such as no deduction for interest payable and foreign exchange losses) before assessed losses but after capital expenditure. A maximum royalty of 5% has been introduced on refined minerals. The effective rate of royalty tax payable for the period ended 30 June 2022 was 0.5% of mining revenue (30 June 2021: 0.5%) equalling the minimum charge per the formula. 6 The Australian operations are subject to a 2.5% (June 2021: 2.5%) gold royalty on revenue as the mineral rights are owned by the state. 7 Minerals are owned by the Republic of Ghana and held in trust by the President. During 2016, Gold Fields signed a Development Agreement ("DA") with the Government of Ghana for both the Tarkwa and Damang mines. This agreement stated that the Ghanaian operations will be subject to a sliding scale for royalty rates, linked to the prevailing gold price (effective 1 January 2017). The sliding scale is as follows: Average gold price Low value High value Royalty rate US$0.00 – US$1,299.99 3.0% US$1,300.00 – US$1,449.99 3.5% US$1,450.00 – US$2,299.99 4.1% US$2,300.00 – Unlimited 5.0% 8 The Peruvian operations are subject to a mining royalty calculated on a sliding scale with rates ranging from 1% to 12% of the value of operating profit. 30 Gold Fields H1 Results 2022

Mining and income taxation The components of mining and income tax are the following: South African taxation – dividend withholding tax (6.1) (13.1) – company and capital gains taxation (1.7) (1.1) – prior year adjustment – current taxation — (1.4) – deferred taxation (45.3) (0.6) Foreign taxation – current taxation (216.4) (176.7) – deferred taxation (4.0) (23.2) Total mining and income taxation (273.5) (216.1) South Africa – current tax rates Mining tax1 Y=34-170/X Y=34-170/X Non-mining tax2 28.0% 28.0% Company tax rate 28.0% 28.0% International operations – current tax rates Australia 30.0% 30.0% Ghana 32.5% 32.5% Peru 29.5% 29.5% 1 South African mining tax on mining income is determined according to a formula which takes into account the profit and revenue from mining operations. South African mining taxable income is determined after the deduction of all mining capital expenditure, with the proviso that this cannot result in an assessed loss. Capital expenditure amounts not deducted are carried forward as unredeemed capital expenditure to be deducted from future mining income. Accounting depreciation is ignored for the purpose of calculating South African mining taxation. During June 2022, the South African Revenue Services published the draft 2022 Rates & Monetary Bill, inclusive of an amendment to the gold tax formula from Y = 34 – 170/X to Y = 33 – 165/X in respect of year assessments ending on or after 31 March 2023, which is considered to be substantively enacted. This resulted in the effective mining tax rate used for deferred tax purposes for Gold Fields Operations Limited ("GFO") and GFI Joint Venture Holdings (Proprietary) Limited ("GFIJVH"), owners of the South Deep mine, decreasing from 29% at 30 June 2021 to 28% at 30 June 2022, amounting to a charge of R76.2m (US$4.9m) through profit or loss. In the formula above, Y is the percentage rate of tax payable and X is the ratio of mining profit, after the deduction of redeemable capital expenditure, to mining revenue expressed as a percentage. 2 Non-mining income of South African mining operations consists primarily of interest income. The corporate income tax rate will be reduced from 28% to 27% for tax years ending on after 31 March 2023, and is considered to be substantively enacted. Deferred tax is provided at the expected future rate for mining operations arising from temporary differences between the carrying values and tax values of assets and liabilities. In South Africa the tax rate which has been used for deferred tax purposes for mining assets is Y = 33 – 165/X and for non-mining assets is 27%, on the basis that these rates are considered to be substantively enacted.

The recoverable amount was based on the fair value less cost of disposal (“FVLCOD”) of the investment (level 2 in the fair value hierarchy). The FVLCOD was indirectly derived from the market value of Lepanto Consolidated Mining Company, being the 60% shareholder of FSE. 2 The US$3.6m in 2022 comprises US$3.0m (June 2021: US$0.4m) impairment of redundant assets in Peru and US$0.6m (June 2021: US$0m) impairment of redundant assets in Chile. 32 Gold Fields H1 Results 2022

Notes to the condensed consolidated financial statements 16. Fair value hierarchy The Group has the following hierarchy for measuring the fair value of assets and liabilities at the reporting date: Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2: Inputs other than quoted prices in Level 1 that are observable for the asset or liability, either directly (as prices) or indirectly (derived from prices); and Level 3: Inputs for the asset or liability that are not based on observable market data (unobservable inputs). The Group recognises transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred. There were no transfers during the periods ended 30 June 2022 and 31 December 2021. The following table sets out the Group's financial assets and financial liabilities by level within the fair value hierarchy at the reporting date: United States Dollars 30 June 2022 (Reviewed) 31 December 2021 (Audited) Figures in millions unless otherwise stated Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Financial assets measured at fair value Environmental trust funds 2.9 — 2.9 — 2.9 — 2.9 — Trade receivables from provisional copper sales 2.6 — 2.6 — 25.8 — 25.8 — Investments – listed 18.6 18.6 — — 30.9 30.9 — — Asanko redeemable preference shares 96.6 — — 96.6 94.5 — — 94.5 Oil derivative contracts 14.6 — 14.6 — 5.1 — 5.1 — Financial assets not measured at fair value Environmental trust funds 109.6 — 109.6 — 85.2 — 85.2 — Loan advanced – contractor 27.3 — — 27.3 27.3 — — 27.3 Financial liabilities measured at fair value Foreign exchange derivative contracts 8.6 — 8.6 — 6.8 — 6.8 — Financial liabilities not measured at fair value Borrowings 1,183.4 1,003.3 — 180.1 1,191.6 1,108.1 — 83.5 Environmental trust funds The environmental trust funds are measured at fair value through profit or loss and amortised cost which approximates fair value based on the nature of the fund's underlying investments. Trade receivables from provisional copper sales Valued using quoted market prices based on the forward London Metal Exchange (“LME”) and, as such, classified within Level 2 of the fair value hierarchy. Listed investments Comprise equity investments in listed entities and therefore valued using quoted market prices in active markets. Asanko redeemable preference shares The fair value is based on the expected cash flows of the Asanko Gold Mine based on the life-of-mine model. The key inputs used in the valuation of the fair value were market related interest rates and expected redemption period. Oil and foreign exchange derivative contracts The fair values of these contracts are determined by using the applicable valuation models for each instrument type with the key inputs being forward prices, interest rates, volatilities and exchange rates.

Total gold mined increased by 18% to 2,728kg (87,700oz) in the June quarter from 2,303kg (74,000oz) in the March quarter mainly as a result of higher reef tonnes due to increased production volumes. Reef yield decreased by 9% to 6.32g/t in the June quarter from 6.92g/t in the March quarter due to a slight reduction in broken reef grade and an increase in gold in process (GIP). Total underground tonnes milled increased by 9% to 437kt in the June quarter from 402kt in the March quarter while surface tonnes milled decreased by 2% to 327kt in the June quarter from 332kt in the March quarter. Development increased by 3% to 2,889 metres in the June quarter from 2,817 metres in the March quarter as a result of an increase in rig production rates, which is in line with the production plan. Secondary support installed decreased by 19% to 3,145 metres in the June quarter from 3,906 metres in the March quarter, due to intermittent support rig machine availability and the redeployment of rigs to conduct primary support. Backfill decreased by 22% to 67,381m3 in the June quarter from 86,418m3 in the March quarter due to reduced stope availability and intermittent pumping infrastructure availability. This decrease will have no impact on the forecast production for 2022. All-in cost was marginally higher at R705,902/kg (US$1,410/oz) in the June quarter from R705,316/kg (US$1,441/oz) in the March quarter mainly due to an increase in capital expenditure and cost of sales before amortisation and depreciation, offset by higher gold sold. Total capital expenditure increased by 23% to R540m (US$35m) in the June quarter from R438m (US$29m) in the March quarter. Sustaining capital expenditure increased by 28% to R455m (US$29m) in the June quarter from R356m (US23m) in the March quarter mainly due to higher spend at the Doornpoort tailings facility, the solar plant and equipment deliveries. Non-sustaining capital expenditure increased by 5% to R86m (US$6m) in the June quarter from R81m (US$5m) in the March quarter due to an increase in spending in new mine development during the current quarter. South Deep obtained approval from NERSA on 16 March 2022 to increase the solar project capacity from 40MW to 60MW. We will deliver self- generation of 50MW in Q3 2022. Project to date expenditure on the plant is R500m (US$32m), with R153m (US$10m) committed bringing the total to R653m (US$42m). The total expenditure to build and commission the plant is estimated to be R700m (US$47m). The construction of the plant is currently 7% behind schedule, and spending is currently 23% behind plan, due to global supply constraints and securing shipping slots, however, the plant is still planned for commissioning in Q3 2022.

Gold production increased marginally to 128,800oz in the June quarter from 128,500oz in the March quarter due to higher tonnes milled. Yield decreased by 2% to 1.14g/t in the June quarter from 1.16g/t in the March quarter due to lower grade ore mined and fed. Ex-pit ore processed in the June quarter was 2.9Mt at 1.12/t compared with 3.1Mt at 1.16g/t in the March quarter. Total tonnes mined, including capital waste stripping, decreased by 3% to 21.3Mt in the June quarter from 22.1Mt in the March quarter in line with the plan. Ore mined decreased by 7% to 3.1Mt in the June quarter from 3.3Mt in the March quarter due to the impact of rain on ore mined at the lower elevations of the Teberebie pit and focus on capital waste stripping. Capital waste stripping increased by 4% to 11.4Mt in the June quarter from 10.9Mt in the March quarter mainly at Teberebie and Kobada pit to expose ore. Operational waste decreased by 12% to 6.9Mt in the June quarter from 7.8Mt in the March quarter in line with the mining schedule. Strip ratio increased by 5% to 6.0 in the June quarter from 5.7 in the March quarter due to the increase in capital waste stripping. Gold mined decreased by 11% to 109.7koz in the June quarter from 122.9koz in the March quarter due to lower ore tonnes mined and grade. Ore tonnes processed increased by 2% to 3,518kt in the June quarter from 3,447kt in the March quarter due to improved overall plant effectiveness. All-in cost increased by 6% to US$1,342/oz in the June quarter from US$1,269/oz in the March quarter due to higher cost of sales before amortisation and depreciation as a result of higher mining cost as a result of the negative impacts of headwinds on diesel and explosive pricing and higher capital expenditure. Capital expenditure increased by 10% to US$63m in the June quarter from US$57m in the March quarter mainly due to higher capital waste tonnes mined and higher mining unit cost.

Total tonnes mined decreased by 69% to 2.0Mt in the June quarter from 6.4Mt in the March quarter. Total waste tonnes mined decreased by 75% to 1.3Mt in the June quarter from 5.3Mt in the March quarter due to a reduced strip ratio at the Akwasiso pit and suspension of mining activities at the Esaase pit. Ore tonnes mined decreased by 37% to 0.7Mt in the June quarter from 1.1Mt in the March quarter accordingly. All-in cost decreased by 7% to US$1,519/oz in the June quarter from US$1,639/oz in the March quarter mainly due to higher gold sold, partially offset by higher capital expenditure.

Total capital expenditure increased by 40% to US$4m in the June quarter from US$3m in the March quarter. Sustaining capital expenditure increased by 173% to US$3m in the June quarter from US$1m in the March quarter mainly due to the start of TSF stage 7 and Nkran and Esaase drilling in the June quarter. Non-sustaining capital expenditure decreased by 64% to US$1m in the June quarter from  US$1m in the March quarter mainly due to reduced expenditure as planned.

Total tonnes mined increased by 22% to 7.2Mt in the June quarter from 5.9Mt in the March quarter, mainly due to better climate conditions (dry season), as compared to the rainy season during the March quarter. Ore mined increased by 39% to 3.2Mt in the June quarter from 2.3Mt in the March quarter, and waste mined increased by 12% to 4.1Mt in the June quarter from 3.6Mt in the March quarter. Gold and copper grades mined increased by 15% and 5% respectively, in line with the mining sequence expected for the June quarter. Consequently, gold yield increased by 52% to 0.70g/t in the June quarter from 0.46g/t in the March quarter and copper yield increased by 28% to 0.46% in the June quarter from 0.36% in the March quarter. As a result of the higher total equivalent production, total equivalent gold sold increased by 18% to 70,800oz in the June quarter from 59,800oz in the March quarter. All-in cost per gold ounce sold increased to US$722/oz in the June quarter from a negative US$27/oz in the March quarter mainly due to the effect of a lower copper by-product credit resulting from a lower copper price in the June quarter and higher capital expenditure, partially offset by higher gold ounces sold. All-in cost per equivalent ounce decreased by 5% to US$957 per equivalent ounce in the June quarter from US$1,009 per equivalent ounce in the March quarter mainly due to higher equivalent ounces sold, partially offset by higher capital expenditure. Total capital expenditure increased by 122% to US$11m in the June quarter from US$5m in the March quarter mainly due to an increase in construction activities at the tailings dam during the dry season. Sustaining capital expenditure increased by 228% to US$10m in the June quarter from US$3m in the March quarter mainly due to construction of the tailings dam as explained above and a land acquisition. Non-sustaining capital expenditure was similar at US$2m in the June quarter. In line with the planned mining sequence used to determine the 2022 guidance, equivalent gold production is expected to decrease in Q3 2022, with full year production still in line with guidance provided in February 2022. Salares Norte The Salares Norte project continued progressing during Q2 2022. Total project progress at the end of June was 77% compared to 70% at the end of Q1 2022. Construction progress increased to 9.3% for the three months ended 30 June 2022 compared with 8.8% for the three months ended 31 March 2022. This was an improvement on the back of the COVID-19 impact during Q1. However, construction productivity in Q2 was impacted by difficult weather conditions with snow events, very high winds and extremely low temperatures. Construction progress at the end of June 2022 was 73%. US$94.2m was spent on the project during the quarter, comprising US$82.1m in capital expenditure, US$6.0m in exploration, US$4.5m in other cost, a US$1.4m investment in working capital and a realised loss of US$0.2m on the FX hedge. US$77.5m was spent on the project during Q1 2022. Pre-stripping at the Brecha Principal pit continued as planned and 9.0Mt was stripped during Q2 2022 compared with 10.8Mt for Q1 2022. Project to date pre-stripping is 42.7Mt. The exploration team remains focused on exploring the district, with 4,955 metres drilled for the three months ended 30 June 2021 compared with 6,148 metres for the three months ended 31 March 2021. 50 Gold Fields H1 Results 2022

Independent Auditor’s Review Report on Condensed Consolidated Financial Statements To the Shareholders of Gold Fields Limited We have reviewed the condensed consolidated interim financial statements of Gold Fields Limited, set out on pages 22 to 39 in the accompanying interim report, which comprise the condensed consolidated statement of financial position as at 30 June 2022 and the related condensed consolidated income statement, statements of comprehensive income, changes in equity and cash flows for the six-months then ended, and selected explanatory notes. Directors’ Responsibility for the Interim Financial Statements The directors are responsible for the preparation and presentation of these interim financial statements in accordance with the International Financial Reporting Standard, (IAS) 34 Interim Financial Reporting, the SAICA Financial Reporting Guides as issued by the Accounting Practices Committee and Financial Pronouncements as issued by the Financial Reporting Standards Council and the requirements of the Companies Act of South Africa, and for such internal control as the directors determine is necessary to enable the preparation of interim financial statements that are free from material misstatement, whether due to fraud or error. Auditor’s Responsibility Our responsibility is to express a conclusion on these interim financial statements. We conducted our review in accordance with International Standard on Review Engagements 2410, Review of Interim Financial Information Performed by the Independent Auditor of the Entity. ISRE 2410 requires us to conclude whether anything has come to our attention that causes us to believe that the interim financial statements are not prepared in all material respects in accordance with the applicable financial reporting framework. This standard also requires us to comply with relevant ethical requirements. A review of interim financial statements in accordance with ISRE 2410 is a limited assurance engagement. We perform procedures, primarily consisting of making inquiries of management and others within the entity, as appropriate, and applying analytical procedures, and evaluate the evidence obtained. The procedures in a review are substantially less than and differ in nature from those performed in an audit conducted in accordance with International Standards on Auditing. Accordingly, we do not express an audit opinion on these interim financial statements. Conclusion Based on our review, nothing has come to our attention that causes us to believe that the accompanying condensed consolidated interim financial statements of Gold Fields Limited for the six months ended 30 June 2022 are not prepared, in all material respects, in accordance with the International Financial Reporting Standard, (IAS) 34 Interim Financial Reporting, the SAICA Financial Reporting Guides as issued by the Accounting Practices Committee and Financial Pronouncements as issued by the Financial Reporting Standards Council and the requirements of the Companies Act of South Africa. Other matter Unless stated otherwise, we have not reviewed future financial performance and expectations, guidance provided, non-IFRS measures, including adjusted or normalised financial information, production and sales volumes, yields, all-in sustaining costs, total all-in costs, other non-financial information, and information not required by IAS 34 Interim Financial Reporting, expressed by the directors in the accompanying condensed consolidated interim financial statements and accordingly do not express a conclusion thereon as part of this review. In addition, the comparative information for the statement of financial position is based on the audited financial statements as at 31 December 2021. The comparative information for the condensed consolidated income statement, statements of comprehensive income, changes in equity and cash flows, and related explanatory notes, for the six-months ended 30 June 2021 has not been audited or reviewed.
