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.

The past 12 months have exacted a terrible toll on both our population and our economy – but with vaccine delivery progressing well and a roadmap to reopening now defined, thoughts are rightly turning to recovery.
But let’s be clear – recovery has to be about more than regaining lost ground. Instead, we must aim higher.
If the Covid-19 pandemic has delivered one unexpected positive, it has been a chance to reassess. With so much of our traditional activity on hold, we have had an opportunity to take stock, to re-evaluate our future, and plot a fresh, forward trajectory which truly enables us to build back better.

International science came to the Black Hills of western South Dakota, because that s where the deep hole is. Over the last century, the hole Ross Shaft was sunk 5,000 ft. to give access to lateral tunnels from which gold was extracted from sedimentary rock to a depth of 8,000 ft. Now the opening into the earth is being repurposed into an entranceway for a highly-sophisticated underground physics experiment.
Most of us non-scientists have to wrestle a bit to comprehend the scientific aspect of the project, which is called the
