INDEPENDENCE GROUP NL SUSTAINABILITY REPORT 2017

ABOUT THIS REPORT STAKEHOLDERS AND MATERIALITY This is IGO’s third Sustainability Report. It addresses IGO’s sustainability performance for the financial year ending 30 June 2017 (FY17). It covers all the activities for IGO and its related entities, including the Tropicana Gold Mine, Long nickel mine (known as the Long Operation), Jaguar zinc- copper mine (known as the Jaguar Operation), the Nova nickel-copper-cobalt mine (known as the Nova Operation), the Stockman Project (currently subject to a divestment process), and our various exploration activities including joint ventures. IGO is a 30% owner of the Tropicana Gold Mine. AngloGold Ashanti is the majority owner in this joint venture and manages all aspects of the mine. This report addresses only those limited 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 www.anglogoldashanti.com/en/sus ). It is anticipated that the scope and sophistication of our reporting will grow and improve in proportion to the size of our business and with regard to the environment in which we operate. While it is appropriate that our Sustainability Report evolves, 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 our stakeholders to analyse changes in IGO’s performance, and therefore make relative comparisons to other organisations. Our 2017 Sustainability Report has been prepared in general accordance with the GRI G4 Sustainability Reporting Guidelines. These guidelines have been applied where they are appropriate to the size of our organisation and the nature and location of our activities. While we have focused on the G4 ‘Core’ indicators, we have also included some additional indicators where they refer to a material aspect of our business. We have also reported against some metrics described in the GRI G3.1 Mining and Metals Sector Supplement as they are of interest to our stakeholders. Our methodology in determining what is included in this report is addressed in Stakeholders and Materiality. To aid the cross-referencing of this report’s discussions on IGO’s material aspects to elements of the GRI G4 Sustainability Reporting Guidelines, a separate GRI Content Index has been prepared (refer to Appendix, page 92). There are clearly merits to producing a single integrated annual report incorporating both financial and sustainability reports. However, Australian federal law currently requires hard copies of annual reports to be posted to shareholders who request them. For IGO, this cost is prohibitive and precludes this option. Until such requirements change, it is IGO’s intention to produce its annual Sustainability Report as a stand-alone document. INFORMATION INTEGRITY AND REPORT AUDIT IGO seeks to gather, record, compile, analyse, and disclose information and processes used in the preparation of its sustainability reports in a way that is readily subject to examination and that establishes the quality and materiality of the information. IGO completes assurance reporting on its National Pollutant Inventory (NPI) and GHG emissions as part of our submission to NGERS. IGO also uses the services of various expert consultants to complete a range of internal audit processes. IGO is pleased to advise that, for the first time, key data in the 2017 Sustainability Report has been subject to an independent third-party limited assurance review by BDO Australia Pty Ltd (CAN 133 657 833). Refer to page 90 and 91, which present a letter from our Auditor. IGO has an ongoing process to identify matters that are material to our stakeholders. These include both socio- economic and environmental risks and opportunities with the potential to have a significant negative or positive impact on our business and our stakeholders. Central to this assessment are the views of our stakeholders. We have identified our stakeholders and have sought to understand the matters of interest and/or concern to them. This process included reviewing: • direct surveys of our listed external stakeholders; • community feedback from individual groups and ‘town hall’ meetings; • significant events during the year that related to both IGO specifically and the industry in general; • current public IGO commitments and obligations; • supplier and customer stakeholder research; • analyst and media calls as part of the financial reporting cycle; • approaches from industry watch groups; • peer company reports, daily media monitoring and workforce feedback; and • international sustainability reporting initiatives and sustainability topics raised by key stakeholders, including government and local communities. The materiality assessment process identified 24 material issues, with the top six presented in Figure 3. Following the ranking process, the issues were plotted according to their potential business impact and importance to stakeholders. The IGO Executive Committee and the Board reviewed and approved the ranking of the material issues listed. In turn, the list of material issues has informed our strategic thinking on priorities for business improvement, reflected in the structure and content of this report. 14 — IGO SUSTAINABILITY REPORT 2017
