Australia will benefit from the long-standing world-class mining exploration industry. The new magnetic gradiometer system would greatly enhance their arsenal of geophysical exploration tools, especially for the detection of both magnetically and/or conductive minerals like nickel sulphide. Due to the inherent skin depth issues of conductive cover, a unique condition in Australia, a low frequency electromagnetic survey system is one of the best methods to penetrate the cover and investigate deeper geological structures. The low frequency isolation system developed in this project will improve the survey instrument performance down to 4Hz, providing capability to explore resources about 50-100% deeper than existing instrumentation allows.

澳大利亚将受益于长期存在的世界级采矿勘探行业。新的磁梯度仪系统将大大加强其地球物理勘探工具库，特别是用于探测硫化镍等磁性和（或）导电矿物。由于导电覆盖层固有的趋肤深度问题，这是澳大利亚的独特条件，低频电磁勘探系统是穿透覆盖层并调查更深地质结构的最佳方法之一。本项目中开发的低频隔离系统将使勘探仪器的性能提高到4 Hz，提供比现有仪器更深50-100%的资源勘探能力。
