Our Centre of Excellence for 3D Mineral Mapping was announced Australian Mining’s ‘Explorer of the Year’ last night.
The team, led by Dr Tom Cudahy, developed the world’s first suite of maps that show the mineral composition of the surface of an entire continent. The maps are helping mining companies increase the efficiency and viability of their exploration efforts.

They were generated from a ten-year archive of raw Advanced Spaceborne Thermal Emission and Reflection (ASTER) data collected by NASA and the Japanese Government’s Japan Space Systems.
Already, they have led to a golden discovery by Kentor Gold, a mid-tier gold company with advanced projects in Australia and the Kyrgyz Republic.
After the ASTER maps revealed some previously unknown ‘areas of interest’ Kentor’s senior project manager Rudy Lennartz scoped an area of about one square kilometre 350km outside of Alice Springs. Spot readings showed what Mr Lennartz describes as ‘a lot of good copper, a couple of good gold assays and possibly lead and silver’.
Kentor Gold managing director, Simon Milroys says the ASTER map project is a great example of CSIRO working together with industry.
‘The ASTER maps are a very valuable exploration resource,’ he says.
It looks like Australian Mining agrees too.
The nearly 20-year ASTER project involved CSIRO, Geosciences Australia, NASA, the US Geological Survey, Japan Space Systems, National Computing Infrastructure, the state and territory geological suveys, Auscope Grid and numerous exploration and mining companies.
