MARKET AND DELIVERY ACTIVE CLOSURE PASSIVE CLOSURE We develop our resources and position our products in the market place in ways that support IGO’s investment decision making. Our strategy is based on supplying high-grade metals to meet the growing demand for energy storage. IGO’s corporate development team work with our operations’ teams to align resource management with market needs. Closure is the final phase in an asset’s life cycle. In consultation with stakeholders we plan early for closure, care and maintenance to minimise financial, social and environmental impacts, liabilities and costs. Active closure includes completing earthworks to reshape landforms created by mining activities and ensuring they are stable, safe and suitable for post-closure land use. Where practical, rehabilitation commences during the operational phase and continues progressively until the mine’s closure. Following completion of the closure earthworks, and any demolition and rehabilitation work, mine sites are subject to ongoing environmental monitoring to assess their progress against agreed closure criteria. This typically includes monitoring water quality, rehabilitation processes, successional processes, and any rates of erosion. IGO SUSTAINABILITY REPORT 2019 — 11
