This project aims to determine why deposits of rare earth elements, which are critical for modern devices and technologies such as phones, tablets and plasma screens, are associated with carbonate magmas. The global supply of these critical metals is geopolitically unstable and, although Australia has significant reserves, there is very limited production. By improving our understanding of the geochemical behaviour of the rare earths this project aims to develop new reverse-engineering methods for their extraction, which will improve the security of supply of these elements and enhance Australia's role in high-tech industries. The project will enhance the profitability of the Australian resources sector through improved extraction economics and will secure the supply of these critical metals for Australian high-tech industries and export. The outcomes will be targeted initially at junior resource companies that are not yet profitable.

该项目旨在确定为什么稀土元素的沉积物与碳酸盐岩浆有关，稀土元素对手机、平板电脑和等离子屏幕等现代设备和技术至关重要。这些关键金属的全球供应在地缘政治上是不稳定的，尽管澳大利亚拥有大量储量，但产量非常有限。通过提高我们对稀土的地球化学行为的了解，该项目旨在为稀土的提取开发新的反向工程方法，这将改善这些元素的供应安全，并增强澳大利亚在高科技行业中的作用。该项目将通过改善提取经济来提高澳大利亚资源部门的盈利能力，并将确保这些关键金属的供应，用于澳大利亚高科技行业和出口。结果将首先针对尚未盈利的初级资源公司。
