INDEPENDENCE GROUP NL SUSTAINABILITY REPORT 2018

We are pleased to note that, in FY18, IGO finalised the development and release of six IGO Group Environmental Standards. These address: • social and environmental impact assessment • land use and biodiversity management • water management • mineral waste management • hydrocarbon and chemical management • rehabilitation and mine closure. Among these, IGO’s standard on social and environmental impact assessment is most significant. While most mining development is subject to both social and environmental impact assessments as part of the approvals phase of a new mine development, few (if any) continue assessments to determine if the original predictions proved true or otherwise. Similarly, there is little consideration given to the efficacy of measures put in place to control the anticipated impacts. At IGO, we are proud to take a leadership role in this area. Specifically, we are committed to understanding the impacts that our activities have on our host communities and the environments in which we operate. We are committed to ensuring this knowledge informs decision-making processes so we minimise or mitigate against any negative impacts. As a matter of normal operations, IGO will complete ongoing impact monitoring at our operational mines, at mines in care and maintenance, and at closed mines for a designated period prescribed in the mine closure plan. At a minimum, monitoring will continue until IGO understands: • the total area of land disturbed or otherwise impacted upon by activities • changes to ecosystem function, and the composition of fora and fauna present within the area potentially impacted by IGO’s activities • changes to the socio- economic circumstances of our host communities • the adequacy of our impact controls or mitigation activities. In the event of adverse changes, IGO is committed to taking reasonable steps to engage relevant expertise to advise how best to minimise, mitigate, or offset any adverse impacts, and then complete mitigation activities. We invite people to review and comment on any of our Group Environmental Standards. We look forward to sharing the findings that will arise from the work we believe is at the forefront of social and environmental impact assessment. MANAGEMENT SYSTEMS AND PERFORMANCE STANDARDS Chris Tiemann Environment & Community Manager, Corporate PROFILE – CHRIS TIEMANN I joined IGO in July 2016 as the Environment and Community Manager, based in Perth. Having worked FIFO for the previous five years, I saw the role with IGO as an excellent way to balance a desire to continue my professional development and have more time for family and friends. Eighteen months ago, I decided to return to university and applied for a post-graduate scholarship at Curtin. The university had recently opened the Centre for Mine Site Restoration (CMSR), focusing on developing better outcomes for mine rehabilitation and closure. I was successful and joined a number of Australian and international students at the CMSR, supported by IGO. I studied part-time and continued my job with IGO in a full-time capacity. My PhD will investigate legislation and policy relating to mine closure, with particular focus on relinquishment. Relinquishment describes the transition of mined land that has been successfully rehabilitated, to an agreed standard, accepted by government and other stakeholders. Currently, there is no defined process for relinquishment and inadequate legislation to allow it to occur. As a result there are very few examples of mines closing and being relinquished, both within Australia and around the world. I believe that a defined process to achieve relinquishment, supported by policy, will drive improved closure outcomes for the mining industry. It’s been tough, but I have managed to progress my studies, while doing my job at IGO. However, in October 2017 my first son was born, and suddenly managing work, studying part-time and now helping with a new baby, I wasn’t left with much time for anything else. To make time for my family and continue to advance my research, I approached IGO to go part-time (four days a week). My request was granted within weeks and I’ve been grateful for the fexibility that’s allowed me to reduce my hours. I’m now proud to be the first bloke at IGO to go part-time.
