The mine sits within the Great Western Woodlands (GWW), an area of significant biological richness almost 16 million hectares in size. It’s composed predominantly of woodland, shrubland and mallee communities with a high diversity of Eucalyptus species. The GWW surrounding the Nova Operation is characterised by low relief paleo drainage systems, with no defined rivers, creeks or watercourses. Groundwater is typically in aquifers close to the surface, recharging by direct rainfall infiltration. Large supplies are rare, however where they do exist, the water is frequently hyper-saline. The Nova Operation consists of one mining lease and three miscellaneous licences, covering approximately 5,000 ha. In some parts, the mining lease extends into pastoral leases of the Fraser Range and Southern Hills stations. The underground mine consists of two orebodies, Nova and Bollinger, as well as a 1.5 Mtpa processing facility (that produces a nickel concentrate and a copper concentrate) and associated infrastructure. The Ngadju people are the Traditional Owners of the land covering the Nova Operation. The Operation is also located in one of Australia’s largest Indigenous Protected Areas (or IPA’s) as managed by the Ngadju Conservative Aboriginal Corporation. 36 — IGO SUSTAINABILITY REPORT 2018
