IGO Annual Report 2022

Continued growth extensions to the Silver Knight sulphide ore body, proximal to Nova, as well as the further maturation of our knowledge of the geology at the Paterson, Kimberley and newly acquired Broken Hill projects. All that we have achieved in FY22 could not have been possible without our people who have continued to embody the IGO purpose and values and remain highly engaged with our business. Our talented team have helped IGO deliver on our transformation and continue to be bold, passionate, fearless and fun – a smarter, kinder, more innovative team. Their resilience was tested in FY22 as a result of increased COVID-19 infection rates in Western Australia which impacted the health of themselves and their families and necessitated a number of changes to how we operate our business. I am proud of the way in which all our people showed care, adaptability and patience during this time and that we were able to avoid any material disruption to our business. In conclusion, I would like to extend my thanks to the Board, for their support of our growth ambitions and commitment to sustainability, and to our Executive Leadership Team (ELT) for guiding our business through a period of profound growth, change and uncertainty. Thank you also to our people who turn up to work every day with outstanding enthusiasm, knowledge and passion for our purpose and strategy. My gratitude extends to our new colleagues who have joined us from Western Areas. We are delighted to welcome you to our business and look forward to, collectively, embarking on the next phase of the IGO journey – I truly believe we will be better together. Finally, I would like to acknowledge the work of our key contractors, the engagement from our communities and the support from our shareholders. We are looking forward to an exciting future as we continue to build a globally relevant business focused on the sustainable and ethical production of clean energy products. Thank you. Peter Bradford Managing Director and Chief Executive Officer It is my great pleasure to report on another outstanding year for IGO. While there have undoubtedly been challenges throughout the year, our team of amazing people have demonstrated the power of working together toward a shared goal – by Making a Difference. In FY22, we have continued to transform our business into a uniquely positioned supplier of products critical to clean energy. This transformation has included a continuing improvement and development of our distinct culture, which promotes diversity, inclusion, development and care. It has included the ongoing enhancement of how we approach and manage our external stakeholders and improve our environmental credentials. And it has seen us further evolve our portfolio through the successful acquisition of Western Areas. Everyone at IGO can rightfully be proud of what we have achieved in FY22 as our business has become an important participant in the clean energy transition. At the core of our strategy is our belief that we have a critical role to play in the decarbonisation of our planet. Through the nickel, copper, cobalt and lithium products we are delivering to our customers, we are enabling the manufacture of high-performance lithium-ion batteries which, thanks to the accelerating roll out of electrified transport, are helping to displace fossil fuel emissions and the resulting impacts on the environment. We continue to be focused on operating our business to the highest environmental, social and governance standards on the belief that how we work is as important as what we do. Our nickel business, which has recently expanded following the Western Areas transaction, has performed well. Nova nickel production was within guidance and cash costs were better than guidance for FY22, while we continued to advance development of the Silver Knight project. We have also worked quickly to integrate our new colleagues from Western Areas into the IGO family, and progress important programs of work designed to optimise the Cosmos and Forrestania operations and deliver synergies. Our lithium business, which includes the fully integrated Greenbushes Operation and the Kwinana Refinery, has also performed well in FY22, with a strong focus on executing expansion and growth projects. Expansion at Greenbushes has lifted production by 96% over the year, and the Refinery achieved an important milestone through the first production of battery grade lithium hydroxide – the first time this has been achieved in Australia. Exploration and discovery have continued to be a core focus for IGO and remains an area which we believe can deliver excellent organic growth for our business. In FY22, our teams focused on identifying and testing targets across our broad portfolio, while also expanding our target commodities to include lithium and rare earth elements. I highlight the notable progress toward identifying CEO’s Message Nova Core Yard IGO ANNUAL REPORT 2022— 7
