To search for gold back in Ye Olde days, you’d have to pick up your pan and start sifting. Thankfully, we’ve now got a suite of fancy tools to help us find minerals deep underground.
It might sound like science fiction, but we’re using super-charged metal detectors that beam electromagnetic pulses from the sky. We’ve even got satellites in space helping us search for new deposits.
But it’s not all high tech – nature is still giving us plenty of clues. When it comes to gold, termites, ants and even leaves point us in the right direction.
