Nickel contributes approximately $2 billion per year to Australia's export income. Currently 80% of that is coming from sulfide deposits, which are expected to be exhausted within thirty years barring significant new discoveries. Discovery rates have been declining for two decades, as the 'easy' targets have been found, despite a broad increase in nickel exploration expenditure to current levels of around $50 million per year. There is a pressing need for new data sets and techniques to allow industry to target new discoveries based on limited drill sampling of potential host rocks. This project forms part of a broader program to harness the igneous geochemistry of the platinum group elements as a powerful pathfinder in nickel exploration.

镍每年为澳大利亚的出口收入贡献约20亿美元。目前，其中80％来自硫化物的矿床，预计将在三十年内耗尽，但除非有重大新发现。由于发现“轻松”的目标，尽管镍勘探支出大幅增加至目前每年5000万美元的水平，但发现率一直在下降二十年。迫切需要新的数据集和技术，以使行业能够基于对潜在宿主岩石的钻探采样有限的钻探来针对新发现。该项目构成了更广泛的计划的一部分，以利用铂群元素的火成岩地球化学作为镍勘探中的强大探路者。
