Earth’s core is leaking gold and precious metals to the surface, new study reveals

Scientists have uncovered something pretty wild—Earth’s core is slowly leaking gold and other precious metals, which are making their way up toward the surface. This challenges the long-held idea that the core is completely cut off from the rest of the planet. The discovery came from analyzing volcanic rocks, which showed traces of metals that likely originated deep in the core. It suggests there’s more mixing between Earth’s layers than we thought, which could reshape how we understand everything from geology to how valuable metals end up where we can mine them.
