Downward-looking telescope will unlock Australia's mineral wealth

October 17, 2018

Scientist in Australia have created a 10-year plan for how the nation will find natural resources that includes the development of a new downward-looking telescope that can look 300 km (186 miles) beneath the Earth’s surface.

The proposal is one of several launched by the Australian Academy of Science’s National Committee for Earth Sciences.

The 10-year plan highlights how the world’s shift toward mobile device technology, renewable energy sources and electric cars will involve massive increases in demand for copper, cobalt, gold, rare-earth elements and other specialty metals.

The committee’s Chair, professor Sue O’Reilly AM FAA, said one of the challenges for Australian geoscience in the coming decade is to ensure the right infrastructure is in place to know how and where to explore for the critical resources needed for Australia’s future.

“This is where the downward-looking telescope comes in,” O’Reilly said in a release.

“A piece of infrastructure like this would transform our minerals sector by making deep Australia visible. It would give us a new understanding of the vertical makeup of the continent and allow us to direct our mineral exploration efforts in the two-thirds of Australia that aren’t currently cost-effective to explore.”

“By 2030, global demand for cobalt will be 47 times what it was in 2016 so unless we can become self-sufficient in this strategic metal, Australia may be held to ransom with massive price increases and chronic shortages,” O’Reilly said.

“This exemplifies the need to generate new geoscience knowledge that will allow us to explore successfully in the covered areas of Australia.”

The plan also draws attention to the weakness in geoscience in Australia’s education system.

“Geoscience is largely absent in Australia’s school system because of a lack of teachers with qualifications in geoscience. Geoscience should be embedded as a core subject within every level of Australian STEM education and earth science graduates should be incentivised to obtain education qualifications,” O’Reilly said.

The plan also calls for an expansion of Australia’s national computational capability to ensure that Australia retains and extends its lead in geoscience simulation and modelling capability.

The National Committee for Earth Sciences acknowledges the support of the Australian Research Council, Geoscience Australia, the University of Melbourne, the University of Queensland, Macquarie University and the Australian Geoscience Council in the development of the plan.
