INDEPENDENCE GROUP NL SUSTAINABILITY REPORT 2018

The Jaguar Operation is located approximately 60km north of Leonora, in the north-eastern Goldfields. It comprises mining and exploration leases and sits in a region that has been, and continues to be, subject to extensive exploration, mining and ore processing activities. In May 2018, IGO announced the divestment of its Jaguar Operation to Round Oak Minerals Pty Limited (Round Oak), formerly CopperChem Pty Limited. This transaction was completed on 31 May 2018. Data relating to Jaguar’s environmental and socio- economic performance for the period of ownership (July 2017 to May 2018) has been included in this report. The sale of the Jaguar Operation was driven by IGO’s strategic focus on high-margin assets of scale and longevity, which were also aligned to the emerging super-cycle for energy storage minerals. IGO was acutely aware of the impacts associated with the announcement and consequently completed workforce and community briefings in collaboration with Round Oak. As Round Oak intends to continue operating the mine in its current state, it is anticipated that there will be few organisational changes in the near term. CONSUMABLES The main consumables used at Jaguar in FY18 were natural gas, diesel, grinding media (steel balls) and explosives. The Jaguar power station, fuelled natural gas (CNG), produces the majority of the Operations’ power demand. However, some areas (e.g. the Jaguar accommodation village) are powered by local diesel- fuelled generators where power lines have not been installed. Groundwater is recovered from the Bentley underground mine, and used in the processing plant, reused underground, and for exploration activities. Water is also recovered from the tailings dam and reused in the processing plant as required. Any surplus water is discharged into the historic Teutonic Bore open pit mine. WASTE The key waste streams from the mine are waste rock and tailings. Waste rock is extracted from underground and placed in above-ground waste rock dumps. Some of this material is classified as potentially acid-forming (PAF). The Jaguar Operation preferentially selects PAF waste rock for use in the production of cement aggregate fill to enable its return underground. Tailings are generated by the mining process and are pumped to the tailings storage facility for disposal. The tailings are then radially deposited within the facility to allow them to settle, forming a ‘beach’ that drains to a central pond. A small volume of both putrescible and inert waste is disposed of in the on-site landfill.
