Independent reasonable assurance statement to Gold Fields Limited

ERM Southern Africa (Pty) Ltd ("ERM") was engaged by Gold Fields Limited ("Gold Fields") to provide reasonable assurance in relation to selected information set out below and presented in Gold Fields' 2022 Integrated Annual Report for the year ended 31 December 2022 (the "Report").

OUR OPINION

In our opinion, the selected information as described under 'scope' above is fairly presented, in all material respects, in accordance with the reporting criteria.

EMPHASIS OF MATTER

Without affecting our opinion, we draw attention to the explanatory notes provided by Gold Fields in Energy and carbon management of the Report relating to the total emissions avoided for the group, which includes projects at Tarkwa and Damang mines that are recognised as exceptional continuous projects by the Gold Fields Group Head of Energy and Carbon.

OUR ASSURANCE ACTIVITIES

Considering the level of assurance and our assessment of the risk of material misstatement of the selected information presented in the Report, a multi-disciplinary team of sustainability and assurance specialists performed a range of procedures that included, but was not restricted to, the following:

• Assessing the appropriateness of the reporting criteria for the selected information presented in the Report.
• A review of external media reporting relating to Gold Fields to identify sustainability issues in the reporting period that may be relevant to the assurance scope.
• Interviews with a selection of staff and management, including senior executives, to gain an understanding of:
  • Gold Fields' sustainability strategy, policies and management systems, including stakeholder engagement and materiality assessment;
  • The status of implementation of the ICMM Mining Principles (including the corporate-level PEs and corporate-level aspects of the combined PEs) and ICMM Position Statements in Gold Fields' strategy and policies;
  • Gold Fields' identification and management of sustainable development risks and opportunities as determined through its review of the business and the views and expectations of its stakeholders; and
  • The relevant management systems and processes (including internal review and control processes) used for collecting and reporting the selected disclosures.
• Reviewing supporting evidence related to external stakeholder engagement on material issues facing the business.
• Confirming that Gold Fields' policies and procedures in effect remain aligned with the ICMM Mining Principles (including the PEs) and other mandatory requirements set out in the ICMM Position Statements in effect as at 31 December 2022.
• Testing the processes and systems, including internal controls, used to generate, consolidate and report the selected information.
• Interviews with management representatives responsible for managing the selected issues.
• A review at corporate level of a sample of qualitative and quantitative evidence supporting the reported information.
• An analytical review of the year-end data submitted by all locations included in the consolidated 2022 group data for the selected disclosures which included testing the completeness and mathematical accuracy of conversions and calculations, and consolidation in line with the stated reporting boundary.
• In-person visits to the following sites to review source data and local reporting systems and controls:
  • Gruyere Mine, Australia;
  • St Ives Mine, Australia;
  • South Deep Mine, South Africa;
  • Tarkwa Mine, West Africa; and
  • Damang Mine, West Africa.
• Virtual visits to the following sites to review source data and local reporting systems and controls:
  • Agnew Mine, Australia;
  • Granny Smith Mine, Australia; and
  • Cerro Corona Mine, Peru.
• Confirming conversion and emission factors and assumptions used.
• Reviewing the presentation of information relevant to the scope of our work in the Report to ensure consistency with our findings.

THE LIMITATIONS OF OUR ENGAGEMENT

The reliability of the assured information is subject to inherent uncertainties, given the available methods for determining, calculating or estimating the underlying information. It is important to understand our assurance opinions in this context.

FORCE MAJEURE

As a result of safety concerns arising from the socio-political unrest in Peru at the time of the planned site visit, we were unable to carry out certain assurance activities as originally planned and agreed with Gold Fields. The in-person visit to Gold Fields' Cerro Corona mine was replaced with remote reviews via teleconference and video calls for this year's assurance engagement. While we believe these changes do not affect our reasonable assurance opinions above, we draw attention to the possibility that if we had undertaken an in-person visit we may have identified errors and omissions in the assured information that we did not discover through the alternative approach.
