Statement by Mike Fraser, CEO At the start of the year, as part of our reviewed results announcement for FY 2023, I highlighted the following five key priorities for our business for 2024 in line with the three pillars of our strategy: • Ensuring the physical and psychological safety of our people; • Safe delivery against our production and cost targets; • Delivery of the Salares Norte ramp up; • Continuing to improve the value and quality of our portfolio; and • Continuing progress towards meeting our 2030 ESG targets. Below I discuss our progress on these for the first quarter of the year (Q1 2024). Ensuring the physical and psychological safety of our people The safety and health of our people is our most important value, and we are committed to ensuring that all our people go home safe and well every day. We have fallen far short of this commitment, and it is with profound sadness that we report two fatalities at our operations this year. On 2 January 2024, a trackless engineering supervisor was fatally injured in an incident involving trackless mining equipment underground at our South Deep mine in South Africa. A second fatal incident occurred at our St Ives mine in Australia on 23 April 2024, when a colleague employed by a contractor, was fatally injured in a mobile equipment related incident at a construction site on the mine. We extend our sincere condolences to the family, friends and colleagues of our two deceased colleagues. These tragic incidents are deeply concerning for us, as we strongly believe that a fatality-free mining business is possible. We have initiated an independent review (being conducted by DSS+, formerly Du Pont) of our Group’s safety culture, processes, systems and practices. The review, which commenced in February 2024, is expected to be completed in the first half of 2024, and will identify opportunities to accelerate our safety journey and standardise the safety approach across our business. Each one of our 23,000 employees and contractors is a safety leader, and we are working with our teams across the business to ensure we have the right safety culture and systems in place to ensure the safety of everyone at Gold Fields. We also recorded one serious injury in Q1 2024 and our Total Recordable Injury Frequency Rate (TRIFR) for the quarter was 3.36 per million hours worked (FY 2023: 2.36 per million hours worked). Our commitment to safety extends to psychological health and wellbeing, which is key to building safe workplaces. We are continuing to progress the implementation of the 21 recommendations of the Elizabeth Broderick and Co independent review and will conduct a follow-up review in 2026. Safe delivery against our production and cost targets Production for the quarter was severely impacted by weather-related events and operational challenges particularly at the Gruyere, St Ives, South Deep and Cerro Corona mines resulting in group attributable equivalent gold production (excluding Asanko) for the quarter being 18% lower year on year (YoY) and 22% lower quarter on quarter (QoQ) to 464koz (Q1 2023: 563koz and Q4 2023: 594koz). The production performance for each of these operations was as follows. SALIENT FEATURES 464,000 ounces of attributable production US$1,738 per ounce of all-in sustaining cost US$2,115 per ounce of all-in cost JOHANNESBURG, 07 May 2024: Gold Fields Limited (JSE and NYSE: GFI) is pleased to provide an operational update for the quarter ended 31 March 2024. Detailed financial and operational results are provided on a six-monthly basis i.e. at the end of June and December. Gruyere Gruyere attributable gold production at 32.2koz was 22% lower YoY (Q1 2023: 41.3koz) and 14% lower QoQ (Q4 2023: 37.3koz) and was negatively impacted by a significant rainfall event in March 2024, which resulted in the damage and closure of the roads that provide primary access to the mine. The roads were closed from 5 March, limiting deliveries of diesel and consumables to the mine, and consequently mining activity and ore processing temporarily ceased. During this time, the mine proactively brought forward planned plant maintenance. In mid-April, the mine was able to receive fuel and consumables, which were delivered utilising alternative routes via South Australia and the Northern Territory where roads had dried sufficiently to allow access. Mining recommenced on 12 April 2024 and plant processing on 14 April 2024. The primary access road to Gruyere was re-opened on 30 April 2024. Ramp up of mining and plant processing to normalised levels were achieved by 21 April 2024. To mitigate against the impact that material weather events can have on production, we will be increasing stock holding of diesel and reagents on a seasonal basis. We are also investigating the establishment and formalisation of an alternative logistics route and network from the east side of the mine. Annual gold production guidance for Gruyere remains unchanged at 150.0koz – 167.5koz with the mine expected to make up the production lost in the quarter in the second half of 2024. Operational update for the quarter ended 31 March 2024 Media Release St Ives Gold production at St Ives at 68.9koz was 26% lower YoY (Q1 2023: 92.7koz) and 37% lower QoQ (Q4 2023: 109.4koz) and was negatively impacted by a decrease in ore mined (following the change in bulk stopes at Invincible as planned) and lower grades. Ore mined from the underground mine reduced to 407kt in the quarter compared to 449kt in Q1 2023 and 570kt in Q4 2023 while the underground grade was 14% lower YoY and 16% lower QoQ. In addition, there was no open pit ore mining at St Ives in Q1 2024 as mining moved to pre-stripping the Invincible Footwall South and Swiftsure open pits, which are expected to commence production of ore during the September 2024 quarter. Gold production for the year is therefore expected to be back-ended to the latter part of the year to achieve the mine’s annual guidance of 355koz, which remains unchanged. South Deep The South Deep mine has had a challenging quarter with operational momentum impacted by the fatal incident on 2 January 2024 (as discussed above), compounded by reduced stope access owing to increased backfill rehandling and slow drilling through crushed ground resulting in slower stope turnaround in current destress cuts. Gold production for the quarter was 34% lower YoY and 32% lower QoQ at 56.3koz (1,750kg). Backfill rehandling is currently presenting the most impactful challenge to production. The mine has developed a recovery plan to address this. The recovery plan is being closely monitored and includes immediate and medium-term actions to: • increase backfill tipping points and address backfill rehandling and backfill leakages; • increase long hole stope drilling capacity and operator competence to allow effective drilling of stopes and through crushed ground; and • improve ventilation, road conditions and service utilities underground. South Deep’s attributable gold equivalent production for 2024 is therefore expected to be in the range of 9,500kg – 9,700kg, in line with gold mined in 2023 (which was 9,600kg). The mine’s AISC for 2024 is expected to be higher than initial guidance at US$1,590/oz – US$1,625/oz, mainly as a result of the lower production volumes. With its significant resource endowment and long life, the focus for South Deep is currently on setting the mine up for longevity, quality ounces and incremental and sustainable production increases. Cerro Corona Attributable gold equivalent production at Cerro Corona at 41.8koz was 44% lower YoY (Q1 2023: 74.7koz) and 19% lower QoQ (Q4 2023: 51.9koz) impacted by lower gold and copper grades processed and lower metallurgical recoveries, in line with the long-term mining plan. In addition, inclement weather during the quarter affected the stability of the north wall of the pit, resulting in a resequencing of mining to lower- grade areas. The stability of the North wall has been addressed and mining operations have resumed. Cerro Corona mine is expected to continue mining until the end of 2025 and thereafter will process stockpiles for five years. We continue to manage the future of the mine in a way that will deliver value for Gold Fields in a responsible manner, whilst balancing the interests of our stakeholders. Group Attributable gold equivalent production and costs Q1 2024 Q1 2023 Q4 2023 QoQ change YoY change Australia 216.0 242.8 308.1 (30) % (11) % South Africa 56.3 84.8 82.8 (32) % (34) % Ghana 149.7 160.4 150.5 (1) % (7) % Peru 41.8 74.7 51.9 (19) % (44) % Lower gold production in the quarter has contributed to a material increase in all-in-sustaining costs (AISC) and all-in costs (AIC) across all our business. Group AISC for continuing operations was US$1,738/oz, 51% higher YoY and 28% higher QoQ while group AIC was 58% higher YoY and 31% higher QoQ to US$2,115/oz for the quarter. The group AIC includes costs for Salares Norte (US$319/oz), Windfall (US$46/oz) and Corporate (US$17/oz). Salares Norte AIC included costs for the project but marginal gold equivalent production for the quarter as first gold was delivered on 28 March 2024. Group AIC for the mining operations (excluding Salares Norte, Windfall and Corporate) were US$1,733/oz (Q1 2023: US$1,142/oz and Q4 2023: US$1,321/oz). Returning production to normalised levels at the operations affected by weather-related and operational challenges is key in the short-term to addressing the material cost increases experienced in the quarter. To address this our current Asset Optimisation programme includes a focus on delivering the 2024 operating plan and proactively identifying medium to longer term opportunities across the business. This involves completing detailed asset diagnostics to assess current performance, outlining potential opportunities, defining improvement initiatives based on constraints and key levers, establishing project charters and developing execution plans with senior asset leaders to deliver and embed priority projects. These initiatives represent operating effectiveness, volume, work quality and elimination of wastage that contribute to improving the AISC. These will be crucial for the long-term sustainability of our operations to offset the risk of margin erosion through persistent inflation. In addition, unit costs and global cost curve position are key considerations for assessing reserve replacement, growth and disposal opportunities as we manage our portfolio to improve the quality and value of the ounces that we produce. An example is the Salares Norte project which with a life of mine AIC of US$820/eq oz (Real 2024$) is expected to markedly improve the group’s AIC. Delivery of the Salares Norte ramp up On 28 March 2024 the Salares Norte project commenced production delivering first gold, a significant milestone for the project that Gold Fields has taken from discovery, through resource and reserve development and project development into production over a 13 year journey. Circuit A and Circuit B of the processing plant, which collectively account for 85% of the annual gold equivalent production, are being commissioned with operational control being handed over to the operational teams. Focus now is on ramp up of the project which is progressing, albeit slower than anticipated due to the impacts of recent early winter weather events. Gold equivalent production for 2024 is now expected to be between 220koz and 240koz at an AIC of US$1,840/eq oz – US$2,010/eq oz. Average gold equivalent production for the first five full years of mine life (2025 – 2029) is expected to be 485koz per annum at an AIC of US$790/eq oz (in real 2024$ terms), while gold equivalent ounces produced over the life of mine (2025 – 2033) is expected to be 360koz per annum at an AIC of US$820/eq oz (in real 2024$ terms). The total project capital cost remains in line with the guidance at US$1,180m – US$1,200m. Salares Norte is expected to have one of the industry's lower cost profiles and a payback period of less than three years at current gold prices contributing meaningfully to our future cash flows, particularly over the next 3 to 4 years. We are undertaking extensive exploration drilling to identify further opportunities to extend the Salares Norte life of mine and expect to spend approximately US$23m on exploration drilling and greenfields opportunities in the area during 2024. Continuing to improve the value and quality of our portfolio Update on Tarkwa/Iduapriem Joint Venture In March 2023 we announced the proposed joint venture between our Tarkwa mine and AngloGold Ashanti’s neighbouring Iduapriem mine in Ghana, that has the potential to create Africa’s largest gold mine. In addition to leveraging operating efficiencies to unlock higher grades and enabling an extension of life to at least 18 years, the joint venture creates compelling shared value for all stakeholders. Since the announcement, AngloGold Ashanti and ourselves have been in ongoing engagement with the Government of Ghana with respect to the proposed transaction. While significant progress has been made agreement has not yet been reached. We will continue to keep the market updated on any developments in this regard. 2 Gold Fields Operational Update March Quarter 2024 Update on Windfall project The Windfall Project in Québec, Canada, which is a 50:50 JV with Canada’s Osisko Mining, is a unique growth opportunity for Gold Fields to partner with Osisko mining to develop a world-class orebody in a sought after, Tier 1 mining jurisdiction. The project’s environmental impact assessment (EIA) was submitted to the regulator in December 2023 with a decision expected by late 2024/early 2025. Once the EIA is approved, construction of the mine will commence, and Gold Fields will settle the C$300m balance of the acquisition price. As part of the partnership, Gold Fields has also acquired a 50% interest in Osisko’s highly prospective Urban Barry and Quévillon district exploration tenements, which total approximately 2,400km2. These will be co-explored and co-developed with Osisko, with Gold Fields funding the first C$75m in regional exploration for the first seven years of the partnership, after which time exploration spend will be shared on a 50:50 basis. Continuing progress towards meeting our 2030 ESG targets During Q1 2024, we made further progress in our journey to achieving the 2030 targets for our six priority ESG areas with a key focus on safety with the appointment of DSS+ as detailed above. Our consistent investments in renewable electricity projects over the past four years are paying dividends in the form of greater energy supply security, reduced energy costs and, of course, a reduction in our carbon emissions. We have made further progress in the year to date. In February 2024, our Board approved the renewable power project at St Ives at a total cost of approximately A$296m (US$195m) with construction commencing in early May. The renewables hub will be the largest in the Group’s portfolio and is expected to provide 73% of St Ives’ energy requirements and deliver a material reduction in the cost of energy for the mine once operational toward the end of 2025. It is set to help reduce the mine’s Scope 1 and 2 emissions by an estimated 50% in 2030 against the 2016 baseline, while increasing the renewables component in the Group electricity mix to 24% from 17% at the end of 2023. In April, we also announced the expansion of our Granny Smith solar plant from 8MW to 19MW, with construction set to commence in June 2024. Among other ESG highlights, our female representation was at 25% at year-end (FY 2022: 23%), over 50% of which are women in core mining roles. We distributed US$3.8bn in value to national economies. Of this, US$1bn – 33% of the total – was shared with our host communities through employment and procurement, as well as SED investments. These achievements and other ESG highlights and challenges are discussed in detail in our 2023 Integrated Annual Report (IAR) suite of reports which was published at the end of March 2024. Financial performance Net debt at the end of the quarter was US$1,143m, compared to US$1,024m at 31 December 2023. The balance sheet remains strong, with net debt to EBITDA at the end of the quarter of 0.51x, compared to 0.42x at 31 December 2023. Gold Fields’ US$500m current outstanding bond becomes redeemable on 15 May 2024. The bond will be redeemed using a portion of the group’s US$1.2bn group revolving credit facility. Update on change to our operating model and executive leadership team The process to transition our operating model from a three-layered organisation (group, region, asset) to a two-layer global functional guidance model (group, assets) is progressing well. The new operating model will provide stronger functional leadership, guidance and support to the assets who, in turn, will be responsible for ensuring safe, reliable and cost-effective production. This structure will also provide more agility as the portfolio evolves. With the regional layer removed, the group’s Australian and African operations will report into Martin Preece, who has been appointed as the Chief Operating Officer (COO). Stuart Mathews, who was previously EVP Australia, retired from Gold Fields, and Joshua Mortoti who was previously EVP: Ghana left the company. Both EVP roles will not be replaced as we transition to the new operating model. The Cerro Corona and Salares Norte mines in South America will continue to report to the EVP South America. As previously indicated Paul Schmidt, has retired as CFO and as a Board member effective from 1 May 2024. The search for a new CFO is in final stages and we expect to make an announcement over the next few months. Until the new CFO is appointed, Alex Dall, the VP Corporate Finance, will act as CFO. Mariette Steyn has been appointed to replace Naseem Chohan as EVP Sustainable Development from 1 June onwards. Naseem will be going on retirement this year and will work with Mariette to ensure a smooth transition. 2024 production and cost guidance unchanged Despite the challenges experienced in the quarter, annual group production and cost guidance for 2024 remain unchanged. 2024 group attributable gold equivalent production (excluding Asanko) is expected to be between 2.33Moz and 2.43Moz, albeit gold production will be weighted to the second half of 2024. Group AISC is expected to be between US$1,410/oz and US$1,460/oz while AIC is guided to be between US$1,600/oz and US$1,650/oz for the year. These include approximately US$60/oz for the 2024 capital expenditure on the St Ives renewable energy project. Excluding the costs for this project, the range for AISC is US$1,350/oz – US$1,400/oz and US$1,540/oz to US$1,590/oz for AIC. Capital expenditure for the year is guided at US$1.130bn - US$1.190bn while sustaining capital is guided to be between US$860m and US$890m (including A$200m (US$132m) to be spent in 2024 on the St Ives renewable project). Non-sustaining capex is expected to be US$270m - US$300m, with the largest component of this being the Salares Norte capital of US$148m and Windfall capital of US$56m. The above is subject to the forward-looking statement on page 17.

This road is the primary access to Gruyere and was subject to substantial damage with ongoing localised flooded sections restricting road access to site for the remainder of the March quarter. Ore processing primarily of low-grade stockpiles continued until 28 March 2024 when a lack of reagents resulted in the closure of the mill and the bringing forward of a planned maintenance shut down. Open pit operations were temporarily restarted after the rainfall until a further closure due to the unavailability of diesel. During April, Gruyere developed options to supply fuel and consumables from South Australia with transport through the Northern Territory and Warburton to the east of Gruyere. Roads along this route were also flooded during March but have since dried sufficiently to restore access albeit over a substantially longer journey. The road was reopened on 30 April 2024. Gold production decreased by 14% to 64,300oz in the March quarter from 74,700z in the December quarter due to a 12% decrease in tonnes milled principally related to the impacts of the rainfall and subsequent shortage of processing consumables and diesel. Focus on pre-stripping of stages 4 and 5 of the Gruyere pit continued during the March quarter, however this was impacted by the rainfall events. Capital waste mined decreased by 15% to 7.31Mt in the March quarter from 8.56Mt in the December quarter and operational waste mined decreased by 37% to 0.25Mt in the March quarter from 0.41Mt in the December quarter. Resultant total waste mined decreased by 16% to 7.57Mt in the March quarter from 8.97Mt in the December quarter. Ore tonnes mined decreased by 41% to 1.02Mt in the March quarter from 1.74Mt in the December quarter due to inaccessibility of the Gruyere pit following the rainfall events and subsequent cessation of mining due to diesel unavailability. Mined grade increased by 10% to 1.32g/t in the March quarter from 1.20g/t in the December quarter due to increased grades of ore mined from Stage 4 of the Gruyere pit. Resultant gold mined decreased by 35% to 43,400oz in the March quarter from to 66,800oz in the December quarter. Total tonnes mined decreased by 20% to 8.59Mt in the March quarter from 10.71Mt in the December quarter. Volumes are expected to increase on the recommencement of mining with signs of improved contractor performance prior to the cessation of mining and the scheduled arrival of additional fleet. AIC increased by 26% to A$2,647oz (US$1,742/oz) in the March quarter from A$2,094oz (US$1,366/oz) in the December quarter due to lower gold sales partially offset by a decrease in capital expenditure. Sustaining and total capital expenditure (on a 50% basis) decreased by 8% to A$26m (US$17m) in the March quarter from A$29m (US$19m) in the December quarter following completion of the pebble crusher upgrade in the December quarter.

Mining operations at Granny Smith were impacted by major rainfall events in the March quarter which forced the closure of the Wallaby Mine portal for 5 days and the subsequent ramp up back to full production, resulting in a decrease of 12% in ore mined to 395,000 tonnes from 449,000 tonnes in the December quarter. The portal is positioned above the pit bottom allowing adequate water storage for rain events. The crews were withdrawn as a safety precaution. A project to upgrade the pumping systems and add redundancy is underway and will be accelerated. Grade mined decreased by 18% to 5.24g/t in the March quarter from 6.36g/t in the December quarter after mining a series of high grade stopes in Zone 60 and Zone 110 during the December quarter. As a result of the decrease in ore and grade of ore mined, gold mined decreased by 28% to 66,500oz in the March quarter from 91,800oz in the December quarter. Yield decreased by 14% to 4.93g/t in the March quarter from 5.71g/t in the December quarter, reflecting the decrease in grade of ore mined. AIC increased by 52% to A$2,299/oz (US$1,512/oz) in the March quarter from A$1,514/oz (US$986/oz) in the December quarter due to lower gold sales and higher capital expenditure. Total capital expenditure for the March quarter increased by 7% to A$28m (US$18m) in the March quarter from A$26m (US$17m) in the December quarter. Sustaining capital expenditure increased by 11% to A$16m (US$10m) in the March quarter from A$14m (US$9m) in the December quarter with increased expenditure on underground mine development in the March quarter. Non-sustaining capital expenditure for the March quarter remained similar at A$12m (US$8m).

Gold Fields Operational Update March Quarter 2024 9 Ore mined from underground operations decreased by 29% to 407kt in the March quarter from 570kt in the December quarter due to planned lower availability of underground ore sources from stoping in the March quarter. Waste mined from underground operations decreased by 10% to 168kt in the March quarter from. 186kt in the December quarter, as a consequence of the lower ore mined during the quarter. Resultant total tonnes mined from underground operations decreased by 24% to 576kt in the March quarter from 756kt in the December quarter. Grade mined from underground operations decreased by 16% to 4.22g/t in the March quarter from 5.03g/t in the December quarter, after mining a series of high grade stopes at Invincible during the December quarter. As a result of the 29% decrease in ore tonnes mined and the 16% decrease in grade mined, gold mined from underground operations decreased by 40% to 55,300oz in the March quarter from 92,200oz in the December quarter. No open pit ore mining occurred in the March quarter (December quarter – 229kt). After completing the Thunderer pit at the end of the December quarter, mining activity has moved to pre-stripping the Invincible Footwall South and Swiftsure open pits, resulting in capital waste tonnes mined of 2.43Mt in the March quarter (December quarter – nil). These pits will commence producing ore during the September quarter. AIC increased by 65% to A$2,954/oz (US$1,943/oz) in the March quarter from A$1,789/oz (US$1,166/oz) in the December quarter due to a 29% decrease in gold sold combined with a 76% increase in capital expenditure. Total capital expenditure increased by 76% to A$57m (US$38m) in the March quarter from A$32m (US$21m) in the December quarter. Sustaining capital expenditure increased by 150% to A$48m (US$32m) in the March quarter from A$19m (US$12m) in the December quarter with A$28m (US$18m) spend on pre-stripping of the Invincible Footwall South and Swiftsure open pits (December quarter – nil). Expenditure on the St Ives microgrid project commenced during the March quarter (A$3m) and will continue for the rest of 2024, with A$200m (US$132m) out of the total project of A$296m (US$195m) planned in 2024. Non-sustaining capital decreased by 34% to A$9m (US$6m) in the March quarter from A$13m (US$9m) in the December quarter due to lower development and infrastructure spend at the Invincible Deeps underground operation.

Ore mined from underground mines decreased by 11% to 280kt in the March quarter from 316kt in the December quarter and waste mined decreased by 22% to 139kt in the March quarter from 179kt in the December quarter with material movement impacted in the Kath orebody at Waroonga by ventilation restrictions following the failure of the primary ventilation fan which has subsequently been remediated. 10 Gold Fields Operational Update March Quarter 2024 Overall grade mined from underground mines decreased by 20% to 6.36g/t in the March quarter from 7.98g/t in the December quarter, with the deferral of higher-grade ore from Waroonga resulting from the primary fan issues. Resultant gold mined from underground operations decreased by 29% to 57,200oz in the March quarter from 81,000oz in the December quarter. Capital waste mined at the Barren Lands pit increased by 115% to 626kt in the March quarter from 291kt in the December quarter, representing works on a minor cutback at the east wall of the pit to ensure long term pit stability whilst being utilised to provide access to the Barren Lands and Redeemer Underground Complexes. The rectification works were completed in the March quarter. Tonnes milled decreased by 10% to 288kt in the March quarter from 319kt in the December quarter due to the decrease in ore mined, and yield decreased by 22% to 5.76g/t in the March quarter from 7.40g/t in the December quarter, reflecting the decrease in grade of ore mined. AIC increased by 34% to A$2,258/oz (US$1,486oz) in the March quarter from A$1,680/oz (US$1,096oz) in the December quarter due primarily to the decrease in gold sold, partially offset by lower capital expenditure. Total capital expenditure decreased by 14% to A$25m (US$16m) in the March quarter from A$29m (US$19m) in the December quarter. Sustaining capital expenditure decreased by 33% to A$17m (US$11m) in the March quarter from A$26m (US$17m) in the December quarter reflecting lower mine development at Waroonga due to the primary ventilation fan failure. Non-sustaining capital expenditure increased by 144% to A$8m (US$5m) in the March quarter from A$3m (US$2m) in the December quarter reflecting increased costs at the Barren Lands and Redeemer Underground Complexes including commencement of the decline and establishment of surface infrastructure.

This was compounded by reduced stope access, due to increased backfill rehandling, and slower stope turnaround in current destress cuts. Consequently, gold produced decreased by 32% to 1,814kg (58,300oz) in the March quarter from 2,669kg (85,800oz) in the December quarter, which was also negatively impacted by grade. Reef grade mined decreased by 19% to 5.25g/t in the March quarter from 6.50g/t in the December quarter, this drop is in line with the business plan which is largely driven by the mining footprint. Total underground tonnes processed decreased by 8% to 415kt in the March quarter from 452kt in the December quarter in line with the lower volumes mined. Gold Fields Operational Update March Quarter 2024 11 Total development increased by 7% to 2,934m in the March quarter from 2,740m in the December quarter as new cut development matured into multiple ends enabling better efficiencies. Backfill decreased by 11% to 109,663m3 in the March quarter from 123,155m3 in the December quarter due to reduced stopes available for backfilling during the quarter. Reef yield decreased by 25% to 5.13g/t in the March quarter from 6.83g/t in the December quarter in line with reduced reef grade, both plant and mine call factors are in line with the business plan. Surface tonnes processed decreased by 10% to 314kt in the March quarter from 348kt in the December quarter due to water constraints as a result of lower-than-normal seasonal rainfall negatively impacting dam levels. Surface yield remained consistent at 0.14g/t in the March quarter. AIC increased by 44% to R1,144,350/kg (US$1,886/oz) in the March quarter from R794,436/kg (US$1,320/oz) in the December quarter, mainly due to the 40% decrease in gold sold quarter on quarter, partially offset by lower cost of sales before amortisation and depreciation and lower capital expenditure in the current quarter. Sustaining and total capital expenditure decreased by 44% to R341m (US$18m) in the March quarter from R613m (US$33m) in the December quarter. The decrease is mainly due to the slow start up of the sustaining projects and the old return water dam upgrade as well as the delivery of replacement fleet in the December quarter, with deliveries in 2024 only planned for later in the year.

Yield increased by 2% to 0.87g/t in the March quarter from 0.85g/t in the December quarter due to the higher grade feed from stockpiles in the March quarter. Mining was completed in the December quarter resulting in the rehandling and treatment of stockpiles in the March quarter. 1,240kt of ore was fed from stockpiles at a grade of 0.96g/t in the March quarter compared to 243kt at 1.15g/t from ex-pit and 963kt from stockpile at a grade of 0.83g/t in the December quarter. There was no material fed from ex-pit in the March quarter due to the completion of Huni and Lima Kwesi Gap pits in the December quarter. AIC decreased by 35% to US$2,063/oz in the March quarter from US$3,189/oz in the December quarter, mainly due to higher gold sold, and lower cost of sales before amortisation and depreciation, partially offset by higher capital expenditure. Cost of sales before depreciation and amortisation decreased mainly due to a lower GIP charge to cost. In the March quarter, the GIP charge to cost was US$29m compared with US$57m in the December quarter which included a US$34m net realisable value adjustment of US$34m of the stockpiles. Excluding the GIP movements for the March quarter, which were all non-cash, AIC would have been US$1,209/oz which is 16% lower than the December quarter of US$1,432/oz applying the same adjustment. Sustaining and total capital expenditure increased by 1,350% to US$2.9m in the March quarter from US$0.2m in the December quarter due to timing of capital expenditure on Far East Tailings Storage Facility raise.
