Reasonable assurance for all Subject Matters

Respective responsibilities:

Gold Fields is responsible for preparing the Report, including the collection and presentation of the selected sustainability information within it, in accordance with the reporting criteria, the design, implementation and maintenance of related internal controls, and for the integrity of its website.

ERM's responsibility is to provide an opinion on the selected information based on the evidence we have obtained and exercising our professional judgement.

Our assurance activities

We planned and performed our work to obtain all the information and explanations that we believe were necessary to reduce the risk of material misstatement to low and therefore provide a basis for our assurance opinion. A multi-disciplinary team of sustainability, Mining Charter and assurance specialists performed the assurance activities, including, among others:

  • Testing the processes and systems, including internal controls, used to generate, consolidate and report the selected Mining Charter information.
  • A review of the suitability of the internal Mining Charter reporting guidelines.
  • Physical visits to the South Deep Mine, South Africa, to verify source data and other evidence.
  • An analytical review of the year-end data submitted by South Deep, including testing of the accuracy and completeness of the consolidated 2019 data for the selected performance indicators.
  • A review of the presentation of information relevant to the scope of our work in the Report to ensure consistency with our findings.

Our assurance opinion

In our opinion, the selected Mining Charter performance information set out in Table 2 for the year ended 31 December 2019 is prepared, in all material respects, in accordance with the reporting criteria.

Our observations

We have provided Gold Fields with a separate detailed management report. Without affecting the opinion presented above, we have the following observations:

  • We recommend giving attention to the consistency of the KPI definitions for the demographic, essential-skills and core skills related indicators, and ensuring these definitions and reporting requirements are aligned to Mining Charter (2018) requirements.
  • The site has made considerable effort during the transition period to adapt to the reporting requirements of the Mining Charter (2018), particularly for procurement subject matters.


The reliability of the assured data is subject to inherent uncertainties given the methods for determining, calculating or estimating the underlying information. It is important to understand our assurance opinions in this context. Our independent assurance statement provides no assurance on the maintenance and integrity of the Gold Fields’ website, including controls used to achieve this integrity, and in particular, whether any changes may have occurred to the information since it was first published.
