IGO SUSTAINABILITY REPORT 2020

BETTER LAND ACCESS Proactively Green mining is characterised by improved land access practices that enable exploration and mining on the most prospective ground. Community concerns strongly influence the way the mining industry is regulated, both by means of statute and by the provision of conditional mining approvals. However, the interests and influence of society has a more profound reach — the concept of having a ‘social licence’ to operate. A company’s social licence is perceived as a function of the effectiveness with which it engages with its host communities and the broader society. At the heart of a social licence to operate is trust and legitimacy. At IGO, we have dedicated considerable resources to community engagement and to shared value creation. Our challenge is to improve the effectiveness of our engagement and the shared value we create. Our progress • We work in collaboration with our host communities and Traditional Owners, creating shared value and strengthening our social licence to operate. Read more on page 76. • Completion of Social and Economic Impact Assessments to examine the impacts on our host communities and focus our engagement programs to address concerns and opportunities. Read more on page 54. • Established land access agreements with the Ngadju people and pastoral station owners of the land on which we operate, to ensure clarity of rights and responsibilities. • Completion of 232,350 hectares of  Cultural Heritage surveys with the Ngadju people in FY20. BETTER RESOURCE UTILISATION Proactively Green mining is characterised by better ways to maximise value from the resources we discover. This includes using less inputs, such as reagents, water and non-renewable energy; capturing more by-products; maximising downstream value-add; and minimising wastes streams of all types including greenhouse gas emissions. IGO’s most significant impacts related to mining are common to the industry: resource use and waste management, including emissions. One of the most effective ways to both minimise emissions and improve productivity is through the electrification and improved automation of mine plant and vehicles, and the increased use of renewable power sources and associated battery technology. A Proactively Green mine will also be the product of better planning and design; we will see mine ventilation design changes with the use of electric vehicles; and mine layout changes given the power of electric semi- or fully- autonomous mining equipment. We will see better by-product capture and recycling, and less water and energy being used per tonne of ore mined and beneficiated. We will see improved efficiencies, less emissions and less waste. Our progress • Nova Solar Farm commissioned in December 2019, generating enough power to displace approximately 6,500 tonnes of CO 2  emissions per annum. • In collaboration with Barminco, we completed a successful pilot of a Safescape Bortana BELV (battery electric light vehicle) at our Nova Operation in FY20. • Implemented remote bogging technology at Nova, allowing automated underground bogging activities to be conducted from the surface, improving equipment utilisation rates, and keeping our operators out of harms way. BETTER EXPLORATION Proactively Green mining is characterised by improved exploration techniques that are more effective at identifying prospective mineral targets, improved frequency of resource discovery, and a reduced need for land clearing and ecosystem disturbance. IGO’s most significant impacts related to our exploration activities are land clearing, habitat fragmentation and ecosystem degradation, coupled with invasive species benefaction. Currently, these impacts are mitigated by the prompt and effective remediation of affected areas and proactive invasive species management. However, in the longer term, a reduction in these impacts will be realised through the application of advanced remote- sensing technologies that will result in a decreased need for land clearing. Remote sensing detects and monitors the physical and spatial characteristics of the earth’s geology by measuring a reflected electromagnetic or acoustic signal. Since the mid-2000s, remote-sensing technologies have undergone substantial advances in data acquisition, processing, and interpretation. Our progress • Use of SpectremAir’s Airborne Electromagnetics platform, Spectrem, to detect sulphide mineralisation to >300 metres deep from the air. • Use of Surpracon’s Low Temperature Superconducting Quantum Interference Devices (SQUIDs) to detect mineralisation to depths up to 1,200 metres. • Utilising drone technology — IGO have partnered with Amira Global to develop UAV-mounted Geophysical Sensor Arrays to improve our exploration techniques. Read more on page 90. • Investigating the application of laser induced breakdown spectroscopy (LIBS) (that is machine learning that integrates geophysical and geochemical data to enhance deposit targeting). BETTER RESOURCE ACCESS Proactively Green mining is characterised by new technologies enabling deeper mining and the recovery of more diffused mineral resources. One of the greatest challenges facing the industry in the mid- to long-term is the likely decrease in the number of near- surface economic ore bodies discovered. This will drive companies to develop new technologies. Our progress • Upgrade of the Nova Operation underground Wi-Fi system in FY20, improving efficiency, safety and communication of our underground operations. • Implemented remote bogging technology at Nova, as described above. • Completed a successful pilot of a Safescape battery electric vehicle, as described above. 28 — IGO SUSTAINABILITY REPORT 2020 PROACTIVELY GREEN IGO SUSTAINABILITY REPORT 2020— 29
