Dr Caroline Tiddy, a Senior Research Fellow in UniSA’s Future Industries Institute, has developed a suite of geochemical tools to more accurately target valuable mineral deposits and save drilling companies millions of dollars in the process. The tools use data collected from analysing drilling materials in new ways to help locate undiscovered precious metals buried by younger sediment and identify the right drill holes.
“The global demand for copper and gold is growing, but it is getting increasingly hard to find these metals as companies are forced to drill deeper and deeper, costing them significant amounts of money,” Dr Tiddy says.
“Diamond drilling, for example, costs up to $400 a metre and it is not uncommon to drill to depths of 1-2 kilometres. That amounts to an $800,000 bill with no guarantee of success, so it limits the number of drill holes. To add to the challenge, ore deposits are tiny compared to the search space. It’s a real life, global problem of looking for a needle in a haystack.”
Dr Tiddy’s goal is to develop new technologies for faster, cheaper and more environmentally-friendly drilling.
