Next Generation Mineral Mapping to re-invigorate exploration in
Queensland's mineral explorers are about to benefit from new advances in
mineral mapping technologies.
New data gathering systems are now becoming available with operational
airborne sensors, including the Australian HyMap(tm) system, providing
calibrated hyperspectral visible to short wavelength infrared spectra
from the Earth's surface. The next step is to take this data and extract
the mineralogy, so geologists can see what they are really looking at.
CSIRO's Minerals Down Under Flagship Next Generation Mineral Mapping
project is developing this capability. The first tangible results from
the project are a series of over 30 maps to be released by the
Queensland Department of Mines and Energy's Geological Survey of
Queensland in Mount Isa on July 3 and in Brisbane on July 4.
Based on airborne hyperspectral Hymap data and satellite ASTER imagery,
over 20 mineral composition maps cover 8250 square kilometres over
mineralised structures in the Mount Isa region. Another 10 satellite
mineral group maps cover 150,000 square kilometres around the greater
Mount Isa region. The maps are supported by chemical analyses of samples
collected during field validation.
The launch of the maps and a presentation on their interpretation will
be held in the Outback at Isa Mining Museum, July 3 from 9.30am to
11.15am and in Brisbane at 111 George Street, July 4 from 10.15am to
According to CSIRO's Dr Tom Cudahy, "Next Generation Mineral Mapping
aims to empower the exploration industry with mineralogy. The final
vision is a mineral map of Australia which, when combined with the
HyLogging(tm) of every drill core's mineralogy, can provide a 3D mineral
map of the continent."
Next Generation Mineral Mapping is a strong demonstration of the
benefits of scientific collaboration. The Predictive Mineral Discovery
Cooperative Research Centre and the CRC for landscape Environment and
Mineral Exploration have helped to interpret the significance of the
In addition, Geoscience Australia collaborated with the CSIRO-Geological
Survey of Queensland team on how best to process and use Advanced
Spaceborne Thermal Emission and Reflection Radiometer multispectral
satellite data. Other collaborators include HyVista Corporation and the
James Cook University, with funding from the Smart Exploration program.
The Geological Survey of Queensland's Senior Geologist - Remote Sensing,
Mr Mal Jones, is delighted with the release. "The benefits of the new
maps to the exploration industry in Queensland are significant.
Companies can improve their prospect targeting, enabling more efficient
evaluation of their tenements," he said.
"The mineral maps also support the development and evaluation of mineral
emplacement models that lead to greater understanding of mineralising
The release of the maps is expected to re-invigorate exploration
activity in Queensland among junior explorers and well resourced
companies. It is hoped that it will also lead to significant new mineral
