Airborne survey reveals rich mineral deposits in Northern Australia
March 19th, 2019
The Northern Territory and Queensland have shown potential for mineral deposits including gold, copper, nickel, lead, zinc and manganese, an airborne electromagnetic survey (AEM) by Geoscience Australia indicates.
Deposits of critical minerals such as cobalt, platinum-group elements and rare earth elements have also appeared in the results.
This is the second release from the AEM survey, which contains 60,000 line kilometres of data that provides insights into mineral-rice areas in Northern Australia that have not been extensively explored previously, according to Minister for Resources and Northern Australia Matt Canavan.
“This is great news for Northern Australia, offering enormous potential for the next generation of resource discoveries,” Canavan said.
“Airborne electromagnetic surveys – or AEM – use aircraft-mounted equipment to map the electrical conductivity below the Earth’s surface to a depth of several hundred metres.
“This provides a detailed 3D picture – similar to a CT scan – that is used to map potential resources beneath the Earth’s surface in the prospective area between Tennant Creek and Mt Isa.”
When integrated with other datasets such as gravity, magnetic and radiometric maps of Australia, the AEM can reveal potential broad-scale groundwater resources to support communities, industries and the environment. Read more…
