ABOUT THIS REPORT This is IGO’s sixth Sustainability Report and presents our sustainability performance for the period 1 July 2019 to 30 June 2020 (FY20). The report is produced to provide our stakeholders with a transparent account of how we address the most material sustainability issues our Company faced during FY20. It forms part of IGO’s annual corporate reporting suite and is best read in conjunction with IGO’s 2020 Annual Report, in addition to other IGO communications available online at www.igo.com.au The report has been prepared in accordance with the Global Reporting Initiative (GRI) Sustainability Reporting Standards (Core option) and the GRI Mining and Metals Sector Supplement. Although we report against the GRI Core option, we have reported above and beyond what is required to ensure full transparency. The report addresses those aspects deemed material to IGO and our stakeholders. For details on the approach of this Sustainability Report and a copy of the GRI Content Index, refer to page 102. The report covers activities currently under exploration and discovery, projects in development, managed operations, joint ventures and divested assets for IGO and its subsidiary companies. All performance data relates to IGO-managed operations only, unless otherwise stated. Where applicable, information and performance data are included for the non-managed Tropicana Joint Venture. Additional information about sustainability performance at the Tropicana Operation can be found online at www.anglogoldashanti.com All dollars are expressed in Australian dollars unless otherwise stated. We engaged an independent external assurance organisation, BDO Audit (WA) Pty Ltd, to provide the directors of IGO with assurance on selected subject matter and criteria, as explained in the independent limited assurance engagement letter on page 121. We value feedback from our stakeholders.
