Pioneering study gives new insight into formation of copper deposits A groundbreaking study has given new insights into how copper deposit-forming fluids are transported naturally from their source deep underground towards the Earth’s surface. A team of geologists, led by Lawrence Carter from the University of Exeter’s Camborne School of Mines, has published a new theory for how porphyry copper deposits form. Porphyry deposits provide around 75 per cent of the world’s copper which is in increasing demand for electric vehicles, power infrastructure and green technologies such as wind turbines. They originally develop several kilometres below the Earth’s surface above large magma chambers. Not only are porphyry deposits rare but most large near-surface examples have already been found. Any new model for how and where they form will be of great interest to mining companies.
