This address was presented at the 2007 Australian Nickel Conference held in Perth, 24-25 October 2007. On the 16 May 2007, the price of nickel metal rose to an all-time record of US$54,200 per tonne, surpassing the previous highest price of $US23,900/t reached in 1988. The nickel price has been surging in response to strong demands, constrained supplies and low metal stockpiles, all reflecting robust worldwide economic growth and especially China's huge need for raw materials. Similar global pressures have also caused the prices of other metals, such as platinum, palladium rhodium, and copper, to rise in recent years. Economic quantities of nickel, platinum, palladium, and rhodium are concentrated in mafic-ultramafic igneous rocks. These particular rocks are a focus for minerals exploration in Australia which has witnessed significant nickel discoveries in past exploration booms. To assist the mining industry during these buoyant times, Geoscience Australia has released a new 1:4 000 000 scale colour map 'A Synthesis of Australian Proterozoic Mafic-Ultramafic Magmatic Events. Part 2: Northern Territory and South Australia'. For the first time on a single map, the continental extent and age relationships of Proterozoic mafic and ultramafic rocks, and associated mineral deposits are shown throughout the Northern Territory and South Australia. Part 1 of this map series that summarises the Proterozoic mafic-ultramafic magmatic events of Western Australia can be found at www.ga.gov.au/minerals/research/pubs/presentations/MUM_ni_mineralisation.jsp The major objective of this presentation is to promote the applications of the new Proterozoic mafic-ultramafic magmatic events map of the Northern Territory and South Australia.
