The following suitable assessment criteria were used in undertaking the work:

  • The WGC RGMP criteria
  • The WGC Conflict-free Gold Standard criteria
  • The ICMM Mining Principles as defined by the following subject matter criteria:
    • ICMM Subject Matter 1: ICMM Principles and relevant PEs, and mandatory requirements set out in the ICMM Position Statements
    • ICMM Subject Matter 2: AngloGold Ashanti’s description of its process for identifying material sustainability issues that meet the principles of completeness and materiality as defined in Global Reporting Initiative (GRI) as well as AA1000AP (2018) adherence criteria for the Principles of Inclusivity, Materiality, Responsiveness and Impact as published

Assurance procedures performed

Our assurance methodology included:

  • Interviews with relevant functional managers from AngloGold Ashanti Group and inspection of information provided to test and verify the existence and completeness of procedures and processes in place for adherence to the AA1000AP Standard, ICMM Mining Principles, and the WGC requirements
  • AngloGold Ashanti Group, as well as a combination of desktop and onsite reviews at nine sampled operations across the globe. This involved testing, on a sample basis, the measurement, collection, aggregation and reporting of selected sustainability information at each operation
  • Inspection and corroboration of supporting evidence to evaluate the data generation and reporting processes against the assurance criteria
  • Reliance on Internal Audit work related to select indicators in scope by way of reviewing the scope of work, procedures performed, and outcomes documented
  • Reporting the assurance observations to management as they arose to provide an opportunity for corrective action prior to completion of the assurance process
  • Assessing the presentation of information relevant to the scope of work in the Report to help ensure consistency with the assurance observations

Engagement and inherent limitations

IBIS planned and performed the work to obtain all the information and explanations believed necessary to provide a basis for the assurance conclusions for High and Moderate levels of assurance respectively in accordance with AA1000AS v3.

The procedures performed at a Moderate assurance level vary in nature from and are less extensive than for High assurance in relation to risk assessment procedures, including an understanding of internal control, and the procedures performed in response to the assessed risks. As a result, the level of assurance obtained for a Moderate assurance engagement is lower than for High assurance as per AA1000AS v3.

Conversion factors used to derive emissions and energy used from fuel and electricity consumed, are based upon information and factors derived by independent third parties. The assurance work did not include an examination of the derivation of those factors and other third-party information.

IBIS experienced no limitations to the agreed extent of work required for the engagement. The scope of work did not extend to any subject matters other than specified in this assurance statement.

Assurance conclusion

High assurance opinion |

In our opinion, based on the work undertaken for High assurance as described, we conclude that the subject matters in the scope for High assurance have been prepared and disclosed in accordance with the defined reporting criteria and are free from material misstatement.

Moderate assurance opinion |

In our opinion, based on the work undertaken for Moderate assurance as described, we conclude that the subject matters in the scope for Moderate assurance are supported by the evidence obtained.

Key observations and recommendations

Based on the work set out above, and without affecting the assurance conclusions, the key observations and recommendations for improvement are as follows:

In relation to the wgc Standards

AngloGold Ashanti has designed and implemented operational processes and controls to ensure compliance with policies and procedures that conform to the RGMPs requirements. It is also actively monitoring its implementation. IBIS applied the WCG/ICMM Equivalency Matrix to cross-validate AngloGold Ashanti’s Self-Assessments at a corporate level and the following sites: Córrego do Sitio Complex, Cuiabá Complex, Tropicana and Sunrise Dam.

AngloGold Ashanti has prepared and disclosed its 2021 Conflict-free Gold Report in accordance with the WGC Conflict-free Gold Standard and has established appropriate risk management and internal controls from which the reported 2021 information is derived..

In relation to the ICMM Subject Matter 1

AngloGold Ashanti’s corporate statements, together with the reviewed Group policies, management standards and procedures, conforms to and reflect the implementation of the ICMM Mining Principles, Performance Expectations and the related Position Statements.

In 2022 it was agreed for IBIS to focus on WGC’s RGMPs and apply the Equivalency Matrix to ‘read across’ conformance with the equivalent ICMM PEs as a means of validating the above listed entities’ self-assessments.

In relation to the ICMM Subject Matter 2

Inclusivity: AngloGold Ashanti’s Stakeholder Engagement Standard outlines its approach to stakeholder engagement, and the purpose and scope of engagement. AngloGold Ashanti has implemented processes and allocated resources to support stakeholder participation, with each of its operations customising its stakeholder engagement plan to meet the specific requirements of stakeholders in the areas of operation.

It is recommended that AngloGold Ashanti consider reporting on metrics relating to stakeholder engagement outcomes and effectiveness to ensure that it maintains its position as a stakeholder-inclusive company.

Materiality: AngloGold Ashanti has identified its material sustainability matters using a wide range of sources, including stakeholder inputs. It engages in an annual process to determine its material sustainability issues that are integrated into its governance, strategy, and risk management processes. AngloGold Ashanti clearly articulates its process for determining its material sustainability issues and how responses to these issues are developed and implemented.

Responsiveness: AngloGold Ashanti has through its annual reporting and sustainability reporting, developed a process for responding to material sustainability topics and communicating them to stakeholders that is applied across the organisation.

It is recommended that AngloGold Ashanti develop and implement a formal process for tracking responses and communication with stakeholders that is continuous and ongoing, to ensure that it is able to proactively respond to stakeholders, in a way that addresses their needs, concerns and expectations.

Impact: AngloGold Ashanti uses its materiality determination process as a basis to identify its impacts and its impact performance. AngloGold Ashanti has implemented processes to integrate the management of key impacts into strategy, governance, and risk management processes. AngloGold Ashanti has mapped out the SDGs against its material sustainability issues throughout the report, and identified priority SDG targets serving as a contextual framework for measuring and reporting its impacts, both positive and negative.

In relation to the ICMM Subject Matter 3

The processes observed to manage the Group’s material sustainability risks and opportunities have been applied throughout the Group through the implementation of standards and programmes and have been well articulated in the Sustainability Report and Company website. Group Management Standards and Policies define the mandatory minimum requirements set for managing a wide range of sustainability issues.


IBIS observed that appropriate measures are in place to provide reliable source data related to the selected sustainability disclosures in the assurance scope. AngloGold Ashanti has an established sustainability data management system, which assists with the collection and consolidation of sustainability information.

Data inconsistencies that were identified during the assurance process were subsequently corrected by management.

IBIS recommends that additional internal reviews are performed between supporting evidence and the sustainability data management system to ensure that figures are correctly calculated, entered and reported on the system.


AngloGold Ashanti’s process of external validation as observed by IBIS is confirmed to have commenced in September 2022 and is scheduled for completion across all assets over a three-year period. AngloGold Ashanti re-prioritised its asset validation process to align with the combined assurance audit cycle.

A comprehensive management report detailing specific findings and recommendations for continued sustainability reporting improvement has been submitted to AngloGold Ashanti management for consideration.
