It addresses IGO’s sustainability performance for the financial year ending 30 June 2018. It covers all the activities for IGO and its related entities, including the Nova nickel-copper-cobalt mine (known as the Nova Operation), the Tropicana Joint Venture (known as the Tropicana Operation), the Long nickel mine (known as the Long Operation), the recently divested Jaguar zinc-copper mine (known as the Jaguar Operation) and the Stockman Project, as well as our various exploration activities including joint ventures. IGO is a 30% owner of the Tropicana Operation. AngloGold Ashanti Australia Ltd (AngloGold Ashanti) is the majority owner in this joint venture and manages all aspects of the mine. This report addresses only those aspects that are deemed material to IGO and our stakeholders. For additional information refer to AngloGold Ashanti's assessment of the sustainability of its broader activities (refer to ). While our Sustainability Report evolves with our stakeholders expectations, it is also our explicit intention that the structure and nature of the content is materially similar from one year to the next to better enable readers to analyse changes in IGO’s performance, and therefore make relative comparisons to other organisations. Our 2018 Sustainability Report has been prepared in general accordance with the Global Reporting Initiative (GRI) Sustainability Reporting Standards. These have been applied where they are appropriate to the size of our organisation and the nature and location of our activities. This report addresses only those limited aspects that are deemed material to IGO and our stakeholders. Our methodology in determining what is included in this report is addressed in Stakeholders and Materiality (see page 20). To aid the cross-referencing of this report’s discussions on IGO’s material aspects to elements of the GRI Sustainability Reporting Standards, a separate GRI Content Index has been prepared (see Appendices, page 98). Additionally, where IGO’s activities support the UN Sustainable Development Goals (SDGs), these activities are highlighted as described on page 14. INFORMATION INTEGRITY AND REPORT AUDIT IGO seeks to gather, record, compile, analyse and disclose information and processes used to prepare its sustainability reports in a way that is readily available for examination and that establishes the quality and relevance of the information. IGO completes assurance reporting on its National Pollutant Inventory (NPI) and greenhouse gas (GHG) emissions as part of our submission to NGERS. We also use the services of various technical experts to complete a range of internal audit processes. Once again, IGO is pleased to advise that key data in this Sustainability Report has been subject to an independent third‑party review by BDO Audit (WA) Pty Ltd (ACN 133 657 833). 2 — IGO SUSTAINABILITY REPORT 2018
