UWA explores new methods for sedimentary copper mine exploration

Getech, an underground resource locating company, announced that it has joined a team of academics and industry to accelerate research into copper deposits, Mining.com reported. Copper is a key metal needed for renewable technologies.

The three-year Kupferschiefer project, launched in the first half of 2023, aims to examine and analyze previous geological data and compile a map of mineral prospects in the Central European Basin using a petroleum and mineral systems approach.

The project is led by the Center for Exploration Targeting (CET) at the University of Western Australia and involves the University of Warsaw, First Quantum Minerals, Teck Resources and BHP.

Getech said the research team will use an integrated mineralization system approach to search for sedimentary copper deposits, which requires a comprehensive study of the formation and preservation of sedimentary deposits.

Getech said it will rely on its own gravity and magnetic data, as well as global geological models and spatial analysis experience, to provide the research team with clear and revealing insights into subsurface features and structures.

Copper is a highly efficient conductor material that contributes to decarbonization and electrification strategies, playing an important role in the generation, transmission and storage of light, water, geothermal and wind energy.

As the global energy transition continues to advance and demand for copper, a key metal, rises, sedimentary copper mines can provide a promising and more sustainable alternative to bridge the gap between supply and demand.

Currently, this type of deposit accounts for only 20-25% of world copper production and has several advantages over non-sedimentary copper deposits, such as porphyry copper deposits in igneous environments. These deposits are widespread and generally do not require energy-intensive processing methods.

Another advantage of sedimentary copper ores is that they contain large amounts of cobalt. 80% of the world's cobalt comes from sedimentary copper mines, and cobalt is a key material for batteries.

"The world's transition to green energy will require more copper, and it is more important than ever to understand the depositional environment of this deposit to obtain new discoveries," said Howard Golden, senior consultant for critical minerals at Getech and also serves as technical advisor to CET, said at a press conference.

"The processes and data generated by this project can be reused in the global exploration of copper and other underground resources, such as lithium, potassium, phosphorus, and even gold and natural hydrogen," Golden said.

"This could become an innovative resource exploration method.”
