IGO Sustainability Report

Contents About This Report This is IGO’s eighth Sustainability Report and presents our sustainability performance for the period 1 July 2021 to 30 June 2022 (FY22). 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 FY22. It forms part of IGO’s annual corporate reporting suite and is best read in conjunction with the IGO 2022 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 also report 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 106. The Sustainability Report covers activities currently under exploration and discovery, projects in development, managed operations and joint ventures for IGO and its subsidiary companies. All performance data relates to IGO managed operations only, unless otherwise stated. Additional information about sustainability performance at the Tianqi Lithium Corporation can be found online at www.tianqilithium.com.au. Information and full data about sustainability performance for Western Areas Limited assets are not included in the FY22 Sustainability Report given the completion of the transaction occurred on 20 June 2022. Limited Western Areas data can be found on page 105. We engaged an independent external assurance organisation, BDO Audit (WA) Pty Limited, 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 126. We value feedback from our stakeholders. Please forward any comments on this report or requests for additional information to contact@igo.com.au. Forward-Looking Statements This report includes forward-looking statements regarding future events, conditions, circumstances, and the future performance of IGO. Often, but not always, forward-looking statements can be identified by the use of words such as ‘may,’ ‘will,’ ‘expect,’ ‘intend,’ ‘plan,’ ‘estimate,’ ‘anticipate,’ ‘continue’ and ‘guidance,’ and may include statements regarding plans, strategies and objectives of management, anticipated production or construction commencement dates and expected costs of production outputs. Such forecasts, projections and information are not a guarantee of future performance and involve unknown risks and uncertainties, many of which are beyond IGO’s control. This may cause actual results and developments to differ materially from those expressed or implied in this Sustainability Report. Relevant factors, including those identified as risk factors, are set out in our 2022 Annual Report. Forward-looking statements only apply at the date of issue. Except as required by applicable regulations or by law, IGO does not undertake any obligation to publicly update or revise any forward-looking statements, whether as a result of new information or future events.
