Response:

The Company respectfully acknowledges the Staff’s comment. Beginning with the annual report on Form 20-F to be filed for the fiscal year ended December 31, 2023 (the “ 2023 Form 20-F ”), the Company proposes to incorporate the ownership interest information contained under the subheading “Strategic Investments” on page IAR-84 of the 2022 Form 20-F as well as the location, size, stage, mine type, commodity and mineralisation style of each of its Non-Core Investments (as defined below), under the new heading “Non-Core Investments” in the section entitled “Summary disclosure of mining operations pursuant to Item 1303 of Regulation S-K under the Securities Act”. The Company will also present maps displaying the location of all such investments in accordance with Item 1303(b)(1).

The Company confirms that this disclosure, including Gold Fields’ relevant shareholding and market value of such holdings, constitutes the information related to such investments as the Company considers material to an investor’s understanding of its mining operations in the aggregate pursuant to Item 1303(b)(2)(iii). For completeness, the Company respectfully submits the basis of its materiality assessment as follows:

Over the years, Gold Fields has acquired interests in the capital of several smaller mining and mineral exploration companies. As at December 31, 2022, Gold Fields held minority shareholdings in Galiano Gold Inc. (“ Galiano Gold ”), Rusoro Mining Ltd., Chakana Copper Corp., Magmatic Resources Limited, Lefroy Exploration Ltd., Lunnon Metals Ltd., Hamelin Gold Ltd., Torq Resources Inc., Tesoro Gold Limited and Far Southeast Gold Resources (together, the “ Non-Core Investments ”).

The below table sets out Gold Field’s interest in each of the Non-Core Investments, along with the respective market value, carrying value and percentage of total assets of each as at December 31, 2022.

Investment	As at December 31, 2022 — Capital stake	Market value of shareholding	Carrying value of shareholding		Carrying value as percentage of total assets

Others (3)	—	1.6		1.6		0.02 %
Total		80.2		46.8		0.64 %

Notes:

(1) As at December 31, 2022, Gold Fields held a 9.8% stake in Galiano Gold. The market value of this capital investment was U.S.$11.7 million, of which Gold Fields recognised a carrying value of U.S.$11.7 million (0.16% of total assets) for the fiscal year ended December 31, 2022. In addition to this capital shareholding, Gold Fields has a joint venture with Galiano Gold pursuant to which Gold Fields, through a subsidiary, holds a 45% interest in Asanko Gold Ghana Limited (“ Asanko ”), Galiano Gold’s sole mining property. Gold Fields has provided the summary disclosure required under Item 1303(b)(1) in respect of its interest in Asanko in the 2022 Form 20-F.

(2) As at December 31, 2022, Gold Fields held a 40% stake in Far Southeast Gold Resources, which manages the Far Southeast project in the Philippines. Gold Fields has determined that there is currently no reasonable prospect of economic extraction from the project and that the market value and the carrying value of its investment in the project was nil for the year ended December 31, 2022.

(3) Represents de minimis investments in AngloGold Ashanti Limited, RareX Limited, Australian Gold and Copper Limited, Orsu Metals Corp., Vizsla Copper Corp. and Amarc Resources Ltd.

Based on the above analysis, and in light of the principles-based disclosure contemplated by Item 1303(b)(2)(iii), the Company will disclose the location, size, stage, mine type, commodity and mineralisation style of each Non-Core Investment in tabular format in the 2023 Form 20-F as well as the type, amount and value of its interests in such Non-Core Investments. Except with respect to Asanko, in respect of which Gold Fields will continue to provide the summary information set out in Item 1303(b), the Non-Core Investments have only a de minimis impact on the Company’s financial results and are not material from a strategic, operational or reputational perspective or in any other respect. The Company has therefore determined that there is no substantial likelihood that a reasonable investor would attach importance to additional information on the mining properties of its Non-Core Investments in determining whether to invest in Gold Fields’ securities.

In Appendix A, the Company has produced the information to be presented under the heading “Non-Core Investments” in the 2023 Form 20-F and future Form 20-F filings thereafter.

Exhibits

1. We are unable to locate your mining and processing schedule in the Cerro Corona Copper and Gold Mine technical report summary dated December 31, 2022, filed as Exhibit 96.8. For example, page 95 includes a reference to the Cerro Corona Copper and Gold Mine mining and processing schedule in Section 12.2, however the schedule appears to be missing. Additionally in Table 19.1.1 on page 96 of the Cerro Corona technical report summary, we are unable to reconcile the quantities sold, with the LOM processed, when applying the recovery percentage. Please advise.

Response :

The Company acknowledges the Staff’s comment. The Company confirms that the reference to the Cerro Corona Copper and Gold Mine mining and processing schedule in Section 12.2 on page 95 of the Cerro Corona Copper and Gold Mine technical report summary dated December 31, 2022 (“ 2022 Cerro Corona Technical Report Summary ”) was a typological error and should instead reference the processing schedule in section 14.2. Further, Table 19.1.1 on page 96 of the 2022 Cerro Corona Technical Report Summary also contained minor errors of a non-material nature, arising from a minor variation when depletion was applied in the calculation of metal content as between the techno-economic and reserve models. The Company submits that as a result, tables 1.4.1, 1.5.1, 11.2.1, 14.2.1, 18.2.1, 19.1.2, 19.3.1, 19.3.2, 19.3.3, 19.3.4, 19.3.5., 19.3.6 and 19.3.7 as well as text in Sections 1.8 and 19.1 of the 2022 Cerro Corona Technical Report Summary included similar minor errors related to the application of the depletion and calculation of metal content. The Company will file an updated technical report summary for Cerro Corona for the year ending December 31, 2023 as exhibit 96.8 to the 2023 Form 20-F (the “ 2023 Cerro Corona Technical Report Summary ”) to correct these non-material errors in the 2022 Cerro Corona Technical Report Summary.

In Appendix B, the Company has reproduced Tables 1.4.1, 1.5.1, 11.2.1, 14.2.1, 18.2.1, 19.1.1, 19.1.2, 19.3.1, 19.3.2, 19.3.3, 19.3.4, 19.3.5., 19.3.6 and 19.3.7 and the text in Sections 1.8 and 19.1 of the 2022 Cerro Corona Technical Report Summary with the proposed indicative revisions to be included in the 2023 Cerro Corona Technical Report Summary. Tables 19.1.1 and 19.1.2 contain minor and immaterial indicative adjustments to align the usage of certain units of measurements and the rounding of financial figures.

If you have any questions or further comments, please contact me at 011 27 11 562 9796 or pschmidt@goldfields.co.za.

Notes:

a) Mineral resources are exclusive of Mineral reserves. Rounding of figures may result in minor computational discrepancies.

b) Mineral resources categories are assigned with consideration given to geological complexity, grade variance, drillhole intersection spacing and proximity of mining development.

c) Mineral resources quoted as diluted in-situ metric tonnes and grades. Metallurgical recovery factors have not been applied to the estimates. The approximate metallurgical recovery factors are 85.9% 89% for copper and 66.7% 76% for gold. The metallurgical recovery is the ratio, expressed as a percentage, of the mass of the specific mineral product recovered from ore treated at the process plant to its total specific mineral content before treatment. Cerro Corona mining operations vary according to the mix of the source material (e.g., oxide, transitional, fresh and ore type blend).

d) The metal prices used for the 2022 Mineral resources are based on a gold price of $1,600 per ounce and a copper price of $3.60 per pound. Open pit Mineral resources at the South American operations are similarly based on revenue factor 1.0 pits, appropriate mine design and extraction schedules. The gold price used for Mineral resources approximates 14 % higher than the selected Mineral reserve price.

e) The cutoff grade may vary per mine, depending on the respective costs, depletion schedule, ore type, expected mining dilution and expected mining recovery. The average cutoff grade value applied to the Mineral resources is: $16.4/t.

f) The Mineral resources are based on initial assessments at the resource gold price of $1,600/oz and copper price of $3.60/lb consider estimates of all Cerro Corona costs, the impact of modifying factors such as mining dilution and mining recovery, processing recovery and royalties. Mineral resources are also tested through the application of Environmental, Social and Governance (ESG) criteria to demonstrate reasonable prospects for economic extraction.

g) The Mineral resources are estimated at a point in time and can be affected by changes in the gold price, US Dollar currency exchange rates, permitting, legislation, costs and operating parameters.

h) Cerro Corona is 99.53 % attributable to Gold Fields and is entitled to mine all declared material located within the property’s mineral leases and all necessary statutory mining authorisations and permits are in place or have reasonable expectation of being granted.

Notes:

a) Rounding of figures may result in minor computational discrepancies.

b) Refer to Table 12.5.1 for year-on-year Mineral reserve comparison.

c) Mineral reserve quoted as mill delivered metric tonnes and RoM grades, inclusive of all mining dilutions and gold losses except mill recovery. Metallurgical recovery factors have not been applied to the Mineral reserve figures. The approximate metallurgical recovery factors are 59.5% to 67.9% 76% for gold and 68.8% to 84.4% 89% for copper. The metallurgical recovery is the ratio, expressed as a percentage, of the mass of the specific mineral product recovered from ore treated at the process plant to its total specific mineral content before treatment. The recoveries for Cerro Corona vary according to the mix of the source material (e.g., oxide, transitional fresh and ore type blend) and method of treatment.

d) The metal prices used for the 2022 life-of-mine (LoM) Mineral reserves are based on a gold price of $1,400/ounce and $3.40/lb copper. Open pit Mineral reserves at Cerro Corona are based on optimised pits and appropriate mine design and extraction schedules. The gold price and copper price used for Mineral reserves is detailed in Chapter 16, Marketing.

e) Dilution relates to planned and unplanned waste and/or low-grade material being mined and delivered to the process plant. Ranges are given for those operations that have multiple orebody styles and mining methodologies. The mine dilution factors are 0 %.

f) The mining recovery factor relates to the proportion or percentage of ore mined from the defined orebody at the gold price used for the declaration of Mineral reserves. This percentage will vary from mining area to mining area and reflects planned and scheduled reserves against actual tonnes, grade and metal mined, with all modifying factors and mining constraints applied. The mining recovery factors are 98 %.

g) The cutoff grade may vary per mine, depending on the respective costs, depletion schedule, ore type, expected mining dilution and expected mining recovery. The average NSR cutoff value applied in the planning process is $16.4/t.

h) An ounces-based Mine Call Factor (metal called for over metal accounted for) determined primarily on historic performance but also on realistic planned improvements where appropriate, is applied to the Mineral reserves. A Mine Call Factor of 100 % has been applied at Cerro Corona.

i) Cerro Corona is 99.53 % attributable to Gold Fields.

d) The metal prices used for the 2022 Mineral resources are based on a gold price of $1,600 per ounce and a copper price of $3.60 per pound. Open pit Mineral resources at the South American operations are similarly based on revenue factor 1.0 pits, appropriate mine design and extraction schedules. The gold price used for Mineral resources approximates 14 % higher than the selected Mineral reserve price based on the three-year trailing average ($1,789.45 per oz) to end December 2022, calculated on a monthly basis of the London afternoon fixing price of gold.

e) The cutoff grade may vary per mine, depending on the respective costs, depletion schedule, ore type, expected mining dilution and expected mining recovery. The average cutoff grade value applied to the Mineral resources is: $16.382/t.

f) The Mineral resources are based on initial assessments at the resource gold price of $1,600/oz and copper price of $3.60/lb consider estimates of all Cerro Corona costs, the impact of modifying factors such as mining dilution and mining recovery, processing recovery and royalties. Mineral resources are also tested through the application of Environmental, Social and Governance (ESG) criteria to demonstrate reasonable prospects for economic extraction.

g) The Mineral resources are estimated at a point in time and can be affected by changes in the gold price, US Dollar currency exchange rates, permitting, legislation, costs and operating parameters.

h) Cerro Corona is 99.53 % attributable to Gold Fields and is entitled to mine all declared material located within the property’s mineral leases and all necessary statutory mining authorisations and permits are in place or have reasonable expectation of being granted.

Notes:

a) Rounding of figures may result in minor computational discrepancies.

b) Refer to Table 12.5.1 for year-on-year Mineral reserve comparison.

c) Mineral reserve quoted as mill delivered metric tonnes and RoM grades, inclusive of all mining dilutions and gold losses except mill recovery. Metallurgical recovery factors have not been applied to the Mineral reserve figures. The approximate metallurgical recovery factors are 59.5% to 67.9% 76% for gold and 68.8% to 84.4% 89% for copper. The metallurgical recovery is the ratio, expressed as a percentage, of the mass of the specific mineral product recovered from ore treated at the process plant to its total specific mineral content before treatment. The recoveries for Cerro Corona vary according to the mix of the source material (e.g., oxide, transitional fresh and ore type blend) and method of treatment.

d) The metal prices used for the 2022 life-of-mine (LOM) Mineral reserves are based on a gold price of $1,400/ounce and copper price of $3.40/lb. Open pit Mineral reserves at Cerro Corona are based on optimised pits and appropriate mine design and extraction schedules. The gold price and copper price used for Mineral reserves is detailed in Chapter 14 Marketing.

e) Dilution relates to planned and unplanned waste and/or low-grade material being mined and delivered to the process plant. Ranges are given for those operations that have multiple orebody styles and mining methodologies. The mine dilution factors are 0 %.

f) The mining recovery factor relates to the proportion or percentage of ore mined from the defined orebody at the gold price used for the declaration of Mineral reserves. This percentage will vary from mining area to mining area and reflects planned and scheduled reserves against actual tonnes, grade and metal mined, with all modifying factors and mining constraints applied. The mining recovery factors are 98 %.

g) The cutoff grade may vary per mine, depending on the respective costs, depletion schedule, ore type, expected mining dilution and expected mining recovery. The average NSR cutoff value applied in the planning process is $16.382/t.

h) An ounces-based Mine Call Factor (metal called for over metal accounted for) determined primarily on historic performance but also on realistic planned improvements where appropriate, is applied to the Mineral reserves. A Mine Call Factor of 100 % has been applied at Cerro Corona.

i) Cerro Corona is 99.53 % attributable to Gold Fields.
