Australia’s national science agency, CSIRO, has unveiled a groundbreaking satellite mapping capability designed to accelerate greenfield mineral discoveries and support the nation’s critical minerals pipeline.
The hyperspectral map processes data from more than 200 narrow spectral bands, offering an unprecedented view of surface mineral composition across the entire continent.
In contrast to previous satellite systems that recorded just 14 bands, this technology enables geoscientists to examine mineral signatures in extraordinary detail.
CSIRO Research Director Dr Sandra Occhipinti described the leap in resolution as akin to hearing a full orchestra rather than a mere 14 notes on a piano.
“Until now, this level of detail could only be obtained by field and laboratory measurements, which can only be done on a smaller scale,” Dr Occhipinti said.
“Remote sensing from satellites opens up our view to the full continent. The technology is so advanced, it has wider applications for agriculture and environmental monitoring.”
To construct the continent-wide dataset, CSIRO researchers created automated workflows to process hundreds of terabytes of data gathered from three international space missions: Italy’s PRISMA, Germany’s EnMAP, and NASA’s EMIT.
One of the initial map layers highlights aluminium sheet silicate mineral abundance, providing critical insight into bedrock footprints surrounding potential ore deposits.
The breakthrough comes as Australia seeks to secure essential supplies of critical minerals for clean energy technologies, advanced manufacturing, and national supply-chain resilience. By pinpointing prospective zones remotely, the dataset aims to significantly reduce the time, financial cost, and exploration risk faced by resource companies.
“This can help explorers target prospective areas more effectively, reducing time, cost and risk in the search for new mineral resources,” said Dr Occhipinti.
Beyond mining, the advanced imaging models hold substantial promise for environmental management, agricultural monitoring, and broader land-use planning.
The new mineral mapping dataset is freely available to researchers and industry professionals through CSIRO’s XT Portal.
