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 2023 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.

Terminology

In this report, IGO may use the terms Indigenous and Aboriginal and Torres Strait Islander peoples interchangeably in different contexts. We respectfully acknowledge that preferred terms and language may vary between jurisdictions.

We use the term Traditional Owners to describe Aboriginal and Torres Strait Islander peoples who have a continuing connection to the lands on which we work and operate, with rights and interests granted under traditional law and customs.

About this Report

This is IGO's ninth Sustainability Report and presents our sustainability performance for the period 1 July 2022 to 30 June 2023 (FY23). 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 FY23. It forms part of IGO's annual corporate reporting suite and is best read in conjunction with the IGO 2023 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 and the GRI Mining and Metals Sector Supplement.

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 105.

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 for Tianqi Lithium Energy Australia Pty Ltd can be found online at www.tianqilithium.com.au.

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 121.

We value feedback from our stakeholders. Please forward any comments on this report or requests for additional information to [e-mail].
