IGO SUSTAINABILITY REPORT 2020

FBI CRC Future Battery Industries Cooperative Research Centre FY financial year or fiscal year (1 July to 30 June) GHG Greenhouse gas Under the Australian Government National Greenhouse and Energy Reporting Act 2007 (NGER), greenhouse gases are the six groups of gases a reporting organisation report against, including: – Carbon dioxide – Methane – Nitrous oxide – Sulphur hexafluoride – A hydrofluorocarbon of a kind specified in the NGER regulations – A perfluorocarbon of a kind specified in the NGER regulations GRI Global Reporting Initiative GRI’s vision is that reporting on economic, environmental, and social performance by all organisations is as routine and comparable as financial reporting. GRI accomplishes this vision by developing, continuously improving and building capacity around the use of the GRI’s Sustainability Reporting Framework. All reporting framework components are developed using a global, multi-stakeholder consensus seeking approach. GWW Great Western Woodlands ha Hectares HPI High potential incidents These incidents are classified as: – All incidents for which the worst credible potential consequence is assessed as being a serious injury (with a lost time injury of greater than two weeks), or a permanent partial disabling injury; and – Those incidents automatically defined as HPIs as per IGO’s reporting standard. These include incidents involving mobile plant and equipment, fires and explosions, falls and falling objects near people, geotechnical failures and inrush, electrical shocks, and pressure vessel failures. ICMM International Council on Mining and Metals IGO IGO Limited (the ‘Company’) IPA Indigenous Protected Area An IPA is an area of land or sea that is voluntarily declared to be a protected area by the Traditional Owners. IPAs are managed in accordance with international guidelines developed by the International Union for the Conservation of Nature. The Australian program was established 1997 by the Australian Government. JV Joint Venture kg Kilogram KWh/t Kilowatt hour per tonne Land clearing Clearing means (a) the killing or destruction of; (b) the removal of; (c) the severing or ringbarking of trunks or stems of; or (d) the doing of any other substantial damage to, some or all of the native vegetation in an area; and includes the draining or flooding of land, the burning of vegetation, the grazing of stock, or any other act or activity that causes (e) the killing or destruction of; (f) the severing of trunks or stems of; or (g) any other substantial damage to, some or all of the native vegetation in the area. Local community Refers to communities that will be impacted directly and indirectly by the organisation’s activities, including exploration, mine operations and those that will be most affected by closure. LTI Loss time injury An injury or illness that results in the employee or contractor being unable to attend work on the next calendar day after the day of the injury, or any day subsequent to that. If a suitably qualified medical professional advises that the injured person is unable to attend work on the next calendar day after the injury, regardless of the injured person’s next rostered shift, a lost time injury is deemed to have occurred. LTIFR Lost time injury frequency rate This is the frequency rate for lost time injuries. It is calculated by the number of lost time injuries / total hours worked (manhours) x 1,000,000 M Million Materiality Materiality is the threshold at which an issue or topic becomes important enough to be reported. Not all material topics are of equal importance, and the emphasis should reflect the relative priority of material topics and indicators. Material topic A topic that reflects a reporting organisation’s significant economic, environmental and social impacts; or that substantively influences the assessments and decisions of stakeholders. ML Megalitre. One million metric litres MLEM Moving-loop electromagnetic surveys MTI Medical treatment injury An injury that either requires treatment by, or under the specific order of, a medical practitioner, or could be considered as being one that would normally be treated by a medical practitioner. MTIFR Medically treated injury frequency rate This is the frequency rate for medically treated injuries. It is calculated by the number of MTI / total hours worked (manhours) x 1,000,000 Mt million metric tonnes Mtpa million metric tonnes per annum MW Megawatt MWh Megawatt hours NGER National Greenhouse and Energy Reporting The NGER scheme is a single national framework for reporting and disseminating company information about greenhouse gas emissions, energy production, energy consumption, and other information specified under NGER legislation. NNTAC Ngadju Native Title Aboriginal Corporation NPAT Net Profit After Tax NPI National pollutant inventory A publicly available internet database of emissions and transfers of 93 substances from industrial facilities and diffuse sources in Australia. Ni Nickel oz Ounce PAF Potentially acid forming PDI Permanent disabling injury An injury that results in a person being totally and permanently disabled (as defined in Western Australian Law) as assessed by a physician to the extent that they are no longer able to work. Reporting period One financial year, beginning 1 July and ending 30 June ROM Run-of-mine pad RWI Restricted work injury Injuries that require an individual to do something other than their normal job. RWIFR Restricted work injury frequency rate This is the frequency rate for restricted work injuries. It is calculated by the number of RWI / total hours worked (manhours) x 1,000,000 Scope 1 greenhouse gas (GHG) emissions Emission of greenhouse gas, in relation to a facility, means the release of gas into the atmosphere as a direct result of an activity or series of activities (including ancillary activities) that constitute the facility. These are emissions owned or controlled by IGO. Scope 2 greenhouse gas (GHG) emissions Emission of greenhouse gas, in relation to a facility, means the release of greenhouse gas into the atmosphere as a direct result of one or more activities that generate electricity, heating, cooling or steam that is consumed by the facility but that do not form part of the facility. These are emissions bought in from third parties. Scope 3 greenhouse gas (GHG) emissions Indirect greenhouse gas emissions other than Scope 2 emissions that are generated in the wider economy. They occur as a consequence of the activities of a facility, but from sources not owned or controlled by that facility's business. SF6 Stock Emissions of sulphur hexafluoride from gas insulated switch gear and circuit breaker applications. 118 — IGO SUSTAINABILITY REPORT 2020 IGO SUSTAINABILITY REPORT 2020— 119 GLOSSARY
