MINING & TECHNOLOGY AUSTRALIA 2014 | ISSUE 8 33 industry challenges today rising exploration costs, diminishing success rates and increased processing is clear; the focus needs to move from domestic competition to domestic "The ARCF will comprise three cuting-edge research tools not co-located anywhere else in the world," he said. A new NanoSIMS to be located at UWA, under lead researcher Professor Mat Kilburn; a Geosciences Atom Probe at Curtin University under lead researcher Professor Steven Reddy; and a Maia Mapper developed by and housed at CSIRO under lead researcher Dr Robert Hough. The new Nano-scale Secondary Ion Mass Spectrometer (NanoSIMS) will enable researchers to understand large-scale phenomena, such as evidence of mineral deposits, through the chemical processes occurring at the nano-scale. "The new NanoSIMS is highly automated and versatile. It can be used for a broad range of applications, including mineral-fuid interactions and determining trace elements of ore deposits in rock," Hunt said. Traditionally, mass spectrometry requires a large volume of material to be extracted from a sample but the NanoSIMS can examine smaller samples and map up to seven elements simultaneously. The Geosciences Atom Probe provides high-resolution three- dimensional characterisation of atom distribution in very small volumes of natural materials. The technology has previously been used in the felds of materials science and nanotechnology but the application to geosciences is in its infancy. "In fact, this will be the frst machine of its kind to be dedicated to resource characterisation in Australia," Hunt said. Recent technological advances have enabled it to be applied to geological materials, to examine changes in the composition over incredibly small (nanometre) distances. Centred in Perth, the NRSP capitalises on the concentration of multinational resource companies located in this recognised mining hub The Maia Mapper is a high-throughput detector system which can be used to produce high-defnition images with microscopic detail in real-time. Combining rapid analysis with high-resolution it will be able to map elemental variations in geological samples. "The NanoSIMS and Geoscience Atom Probe are expected to arrive in 2015 and the construction of Maia Mapper is expected to be completed by 2016," Hunt said. "The ARCF's concentration of advanced instruments and expertise will establish it as a global hub for 'metre-to-atomic scale' analyses." Combined with four-dimensional data integration provided by the Pawsey Supercomputing Centre, the ARCF will be a ground-breaking research facility that will provide a resource focus unmatched anywhere in the world. For industry this will mean more efcient mining and higher production yields. The Distal Footprints project aims to revolutionise the way we search for resources in Australia with a team of the nation's best scientists charged with improving the diminishing success rates of minerals exploration. Focusing on the potentially lucrative Capricorn region of Western Australia, the $16 million project seeks to develop a new way of discovering mineral deposits in the area. "The Distal Footprints project is about addressing the fundamental limitations to mineral discovery," Hunt said. "Although there are potentially huge mineral deposits under its thick surface, the Capricorn region is a poorly explored and poorly understood area. By bringing together some of the best scientists in
