Sustainability Report 2021

Our independence and quality control We have complied with the independence and other relevant ethical requirements relating to assurance engagements, and apply Auditing Standard ASQC 1 Quality Control for Firms that Perform Audits and Reviews of Financial Reports and Other Financial Information, and Other Assurance Engagements in undertaking this assurance engagement. Assurance practitioner’s responsibilities Our responsibility is to express a limited assurance conclusion based on our work performed on the Sustainability report of IGO Limited. We conducted our limited assurance engagement in accordance with the Standard on Assurance Engagements ASAE 3000: Assurance Engagements Other than Audits or Reviews of Historical Financial Information . That standard requires that we comply with ethical requirements, including professional independence requirements, apply Auditing Standard ASQC 1 Quality Control for Firms that Perform Audits and Reviews of Financial Reports and Other Financial Information, and Other Assurance Engagements and plan and perform our procedures to obtain limited assurance about whether any matters come to our attention that causes us to believe that the disclosures relating to the subject matter in the Sustainability Report of the company for the year 1 July 2020 to 30 June 2021 has not been prepared, in all material respects with reference to relevant Global Reporting Initiative (‘GRI’) Standards for sustainability reporting and IGO’s self-determined criteria. This does not mean that separate conclusions are expressed for each subject matter. In a limited assurance engagement, the evidence gathering procedures are more limited than for a reasonable assurance engagement, and therefore significantly less assurance is obtained than in a reasonable assurance engagement. The procedures selected depend on our judgement. In forming our conclusion on the subject matter, we performed, amongst others, the following procedures: • Obtaining an understanding of the structure of the organisation and of the stakeholder engagement; • Review IGO’s processes to identify and determine material topics and sustainability information to be included in the Sustainability Report with examination of underlying materiality assessments; • Determining whether material topics relevant to the subject matter identified during our procedures had been adequately disclosed; • Make enquiries of personnel involved in the preparation of the sustainability report regarding the preparation process, the underlying internal control system and selected sustainability information; • Agreeing Socio-Economic contributions to supporting documentation; • Performing analytical procedures on Scope 1 and Scope 2 emissions, and agree to work performed by external consultant; • Assessing reasonableness of Lost Time Injury Frequency rate, including the underlying inputs; BDO Audit (WA) Pty Ltd ABN 79 112 284 787 is a member of a national association of independent entities which are all members of BDO Australia Ltd ABN 77 050 110 275, an Australian company limited by guarantee.
