New data reveals potential copper "hot spots" in Northern Australia

10 May 2018

Potential copper “hot-spots” in an area on the Queensland-Northern Territory border are revealed in new data released by the Australian Government today.

Minister for Resources and Northern Australia Matt Canavan said these locations were contained in the latest Northern Australian Geochemical Survey (NAGS) data.

“These NAGS data will underpin mineral, agriculture, and environmental resource management between Tennant Creek and Mt Isa,” Minister Canavan said.

“Tennant Creek and Mt Isa are the pre-eminent mineral resource hubs for the Northern Territory and Queensland. The region between them is a vast prospective exploration frontier that has been largely unexplored.

“Surface soil samples were collected at 776 sites in this region and analysed for their metal content. The data reveal new potential for elements such as copper, zinc and nickel.

“Potential ‘hot spots’ with elevated levels of copper have been discovered. Copper is one of the world’s most valuable and sought-after commodities, used in building and construction, but also in devices that benefit our everyday lives, such as electric car batteries, solar panels and mobile phones.

“This result builds on the great work already being done in this region, including the recent release of new seismic data and solid geology maps from the South Nicholson Basin, which showed the basin is three times larger than previously thought; and also the release of regional gravity data, all of which improve our knowledge of the area’s potential energy, mineral and groundwater resources.

“Taken together, this is very exciting news for the Australian minerals sector.”

Minister Canavan said the new geochemical data provided target areas where deposits might exist below the surface.

“These new data are vital to stimulating more exploration activity across Northern Australia, and these first ‘clues’ as to where resources might be located help to ensure responsible development of the north.

“The data are also valuable for agricultural management and environmental monitoring. For example, farmers can use the data and maps to assess soil fertility and inform sustainable crop production and cattle grazing management over areas such as the Barkly Tableland region of the Northern Territory and Queensland.”

Minister Canavan said, while the data reveal great potential, it was too soon to speculate on the exact nature or extent of the resources in the region.

“Additional data from this region, including from an airborne electromagnetic (AEM) survey, will be released later this year, followed by a targeted stratigraphic drilling program in late 2019, to increase understanding of the area’s resource potential.”

Note: Geoscience Australia, as part of the Australian Government’s $100 million Exploring for the Future (EFTF) program, undertook the soil sampling survey in collaboration with the Northern Territory Geological Survey and the Geological Survey of Queensland. The samples were processed by an Aboriginal and Torres Strait Islander Corporation, the Centre for Appropriate Technology (CfAT Ltd).
