Study finds that Earth's core is 'leaking' gold
Researchers have found evidence that Earth's core is leaking gold and other precious metals, according to a new study. The vast majority (99.9 per cent) of Earth's gold and other precious metals are hidden in the centre of our planet, with thousands of miles of near-impenetrable rock between us and these natural treasures. However, while humans are unlikely to ever mine Earth's core, new research indicates that some metals have migrated out of the core into enriched rocks that eventually ended up at the surface.
