APPROACH TO SUSTAINABILITY APPROACH TO SUSTAINABILITY

To fulfill our purpose, we at IGO focus on both the sustainability of our business and the manner in which we do business. By consistently applying our values, we endeavour to create an organisation that generates superior long-term returns for our investors and improves the socio- economic conditions of the areas in which we operate, while eliminating or mitigating any negative impacts.

Our starting point is our adherence to the International Council on Mining and Metals (ICMM) Sustainable Development Principles (refer to www.icmm.com).

CAREFUL AND PERSISTENT EFFORT “We are often faced with tasks that are not part of our regular scope of work, which require us to think outside the box and come up with a solution that is effective, timely and, most importantly, safe.”

22 — IGO SUSTAINABILITY REPORT 2017 PROFILE – DEBRA BAKKER

The appointment of Debra Bakker to IGO’s Board of Directors in late 2016 could be considered a look to the past as well as a confident look into the Company’s future as it was Debra’s persistence – and ultimate success – in persuading her colleagues at Commonwealth Bank of Australia in 2002 to take on the $15 million loan IGO needed to purchase the Long nickel mine. Debra grew up in Perth and completed her Bachelor of Business at Edith Cowan University before moving to Sydney for eight years, firstly for Barclays Bank as a credit analyst before moving into project finance four years later, where she realised that working with the mining industry was where she wanted to be. At a relatively young age, she told her bosses she wanted to move to the Big Smoke of London “and that was the start of my serious mining career” says Debra, who remained there for five years before joining Standard Bank in Chicago, with the proviso that Standard would let her return to Australia after two years. Standard Bank honoured this and Debra returned to Sydney, after which she was lured to New York to work in energy derivatives. Like every member of the IGO Board, Debra brings a diverse skillset to the boardroom. Debra comes to IGO with extensive global experience and has worked with some of the world’s most trusted mining industry leaders. She sees her role on the IGO board as someone who understands corporate finance matters. “Each of our Board members has different skillsets but they bring these to the Board in a wholistic and collaborative way. We work as a team and are stronger for our differences.”

1 EXPLORATION

PASSIVE PROJECT 5 CLOSURE MINING 2 DEVELOPMENT INVOLVES 5 DISTINCT PHASES

ACTIVE 4 CLOSURE 3 OPERATIONS

EXPLORATION IGO is passionate about discovery through innovative exploration both 1 in near-mine areas and on regional belt-scale opportunities.

2 PROJECT Project development involves the definition of economically mineable DEVELOPMENT resources, either as the product of our exploration efforts or through the purchase of prospective ground from other parties. It also involves a number of key steps including undertaking feasibility studies and obtaining environmental approvals.

OPERATIONS Operations involve the extraction of ore from the mine and its beneficiation 3 to produce our saleable products: concentrates that contain gold, nickel, zinc, copper, and cobalt. Operations involve ongoing exploration and resource definition, and ongoing mine design and processing optimisation.

ACTIVE CLOSURE Where practical, rehabilitation works commence during operations and occur 4 progressively until the end of a mine’s economic life. Mine closure planning is completed in consultation with our stakeholders and results in the development of a ‘basis of design’ and ‘mine closure criteria’. Earthworks are completed to reshape the landforms created by our mining activity to ensure they are both safe, stable and suitable for the intended post-closure land use.

PASSIVE CLOSURE Following the completion of closure earthworks, demolition work and 5 revegetation, mine sites are subject to ongoing environmental monitoring to assess their progress against the agreed closure criteria. Typically this includes monitoring of water quality, revegetation, successional processes, and rates of erosion.

IGO SUSTAINABILITY REPORT 2017 — 43 FRASER RANGE PROJECT

WESTERN AUSTRALIA

FRASERFRASER RANGE RANGE PROJECTPROJECT (AU) IGOVarious 70% JV

The Fraser Range Project comprises 100% owned exploration licences, and several joint ventures, including those with AngloGold Ashanti, Buxton Resources, Creasy Group, Orion Gold, Sheffield Resources, TasEx Geological Services and Rumble Resources. In most of the joint ventures IGO owns or is earning a minimum 70% interest in the tenements. The Fraser Range Project area is located approximately 110km east of Norseman and covers over 430km strike length along the Albany-Fraser Belt. This emerging belt is considered highly prospective for both Tropicana-style gold deposits as well as Nova-style magmatic, nickel-copper deposits. While many exploration companies have taken up exploration licences in the Fraser Range, IGO has a competitive advantage derived from our knowledge gained during the exploration, discovery and development of the Nova-Bollinger deposit. Exploration activities over the past year have included surface geochemical sampling, ground-based gravity and moving loop electromagnetic surveys, and drilling to generate and test targets. Parts of IGO’s Fraser Range Project area cover the Boonderoo, Fraser Range, Kanandah, and Southern Hills pastoral leases, which are actively being farmed. Northern parts of the project area fall within the proposed Lake Harris Nature Reserve and the Plumridge Lakes Nature Reserve. Several tenements in the southern part of the project are located within the Dundas Nature Reserve. IGO is required to operate under an approved Conservation Management Plan (CMP) when working in these Class A and B nature reserves. The CMP is designed to provide a framework for environmental management of exploration activities in accordance with Western Australian and Australian Government legislation. One project area in the greater Fraser Range is a joint venture with AngloGold Ashanti, known as Salt Creek. The south- western portion of the Sale Creek Project’s tenure falls under the Environment Protection and Biodiversity Conservation Act (EPBC) Act 1999 as a ‘referral area’. Exploration activities within the area are classified as a ‘controlled action’ and require adherence to an Environmental and Conservation Management Plan (ECMP).

LAKE MACKAY PROJECT (AU) IGO 70%

Early in FY14, IGO entered into an exploration joint venture with ABM Resources NL (ABM). The project includes a 520km2 exploration licence and a further 6,600km2 of exploration licence applications. In addition to this, a joint venture with Castile Resources and ABM covering adjacent exploration licence applications of 900km2 was completed. The Lake Mackay Project area is 450km west-north-west of Alice Springs and is accessed by the Gary Junction Road. The project is within the Great Sandy Desert Bioregion, which is comprised predominantly of semi-arid sand plains and sand dunes. Follow-up drilling of soil anomalies has confirmed primary gold and massive sulphide base metal mineralisation. These encouraging results confirmed the area as a new belt-scale opportunity and led to IGO triggering Phase 2 of its option agreement with ABM in May 2016. By spending $6 million on the project, IGO can earn a 70% interest by May 2020. In October 2016 base metal mineralisation was confirmed during the first drilling program at the Grapple Prospect. The land tenure falls within areas covered by the Aboriginal Land Rights (NT) Act 2006 and access by explorers is covered under various deeds for Exploration with the Central Land Council. All work programs must be submitted to the Central Land Council for approval and meetings are held with Traditional Owners to discuss the proposed activities. Sacred site clearance surveys are also completed by the Central Land Council prior to any on-ground exploration being undertaken.

Other concerns include the industry’s potential impacts on communities and individual’s lifestyles. Of specific and consistent concern is the potential to impact on traditional reindeer herding practices and water contamination. IGO, in association with its joint venture partners, is clearly an advocate for the benefits of mining. We are proud of our track record in best practice, safe and sustainable mining in Australia and being a valued member of the community. In this light, we have sought to pursue our interests in exploration while engaging with the community to address their concerns. We have employed a range of mitigation measures such as planning our activities in winter, where possible, to avoid the calving season of reindeer and the nesting season of bird life and, similarly, to avoid important traditions like the annual moose hunt, which begins 1 September every year. There have been no reported environmental incidents or community complaints in the reporting period.

PROCUREMENT

IGO supports economic development in the communities where we operate by seeking to invest first locally and then regionally within Western Australia, then nationally and finally internationally. At the Long Operation, our highest value contracts are our off-take agreements with BHP Nickel West (which processes IGO ore), diamond drilling and fuel. At the Jaguar Operation our highest value procurement contracts are our transport contracts, underground mining and drilling services, fuel, gas and catering services. These services and materials are sourced from large, reputable organisations with operations throughout Australia. During the construction of Nova, the highest value contract was for the construction of the processing plant, followed by underground mining and drilling services, fuel and catering services. Construction was completed using Australian- sourced labour, except for those modular components of the processing plant, which were fabricated offshore. During operations our highest value contracts were for underground mining and drilling services.

SOCIAL IMPACT SOCIAL IMPACT

IGO is a significant mid-cap mining company in the Australian mining industry. The nature of both our positive and negative impacts are comparable to other miners in the industry and the magnitude of our social impact is proportionate to our size.

Notwithstanding the commonality of these issues to most industry participants, we believe we have six social impact-related material issues worthy of active management (refer to page 15). This section of the report provides commentary on the material issues that IGO regards as most significant to our employees and host communities.

74 — IGO SUSTAINABILITY REPORT 2017 LAND AND BIODIVERSITY MANAGEMENT

Following the Western Australian Department of Mines and Petroleum release of a new guideline for mining proposal development in late 2016, additional information was provided through interactive workshops in FY17. The most significant change is the development of a whole-of-site mining proposal, which is required to be progressively updated as operations are modified. The move to a risk based mining proposal aligns with IGO’s internal risk management process. IGO is also committed to contributing to the conservation of biodiversity within its operating areas. In FY18 IGO will develop a land and biodiversity management standard that will provide our operations with clarity on the required land management practices, aligned to accepted best practice industry guidelines.

IGO SUSTAINABILITY REPORT 2017 — 75 FLORA AND FAUNA

In accordance with our Environmental Policy, IGO is committed to understanding and protecting the flora and fauna communities at each of our operations and project sites. Impact monitoring is currently undertaken to understand the ongoing impact of mining activity through comparative photography at pre-defined photo- monitoring survey points. Periodic surveys are employed to measure impacts to fauna, triggered by the different stages of a project or a proposed modification to an existing operation.

The the Nova Operation. program includes monitoring at both the site’s six artificial water ponds and the tailings storage facility. The artificial water ponds were established to provide preferential water sources to the site’s tailings storage facility to minimise fauna deaths that could occur if fauna use the tailings liquor as a water source. The liquor poses a hazard to fauna because it contains low concentrations of a toxic processing reagent (weak acid dissociable cyanide). In FY17, there were no material losses of wildlife associated with Tropicana’s tailings storage facility.

76 — IGO SUSTAINABILITY REPORT 2017 JAGUAR OPERATION The Jaguar Operation has a long history of mining activities, which have impacted the vegetation within the mining leases. The area is surrounded by pastoral properties and cattle grazing, which together with feral animals and introduced weeds, have also had an impact on the native vegetation. Of note are the large populations of introduced goats, dogs, cats and rabbits. Mulga woodlands and flora typical of the region’s ephemeral creek lines dominate the land surrounding the Jaguar Operation. Field fauna surveys, conducted at the Jaguar Operation recorded 57 bird species, eight native and four introduced mammals, 23 reptiles and four amphibians. A desktop analysis of potential fauna distributions identified three mammal, one reptile and one bird species of conservation significance that could be present in the area due to IGO IS COMMITTED the presence of suitable habitat.

LONG OPERATION The land surrounding the Long Operation, located on the shore of Lake Lefroy, is dominated by Eucalyptus woodlands and halophytic low shrublands. The Long Operation sits within the Goldfields region of Western Australia and is subject to extreme temperatures and periodic rainfall, predominantly in the summer months. Exploration and mining activities have taken place for over 40 years at the Long Operation and the surrounding area. This has resulted in clearing for the construction of infrastructure, waste rock dumps, tailings storage facilities, processing plants, open pits and underground mines. Neighbouring mines and the Long Operation’s proximity to the town of Kambalda, coupled with the historic public land use of the surrounding area has also contributed to the local environment being degraded.
