Money might not grow on trees, but scientists have confirmed that gold is found in the leaves of some plants.
Researchers from Australia say that the presence of the particles in a eucalyptus tree's foliage indicates that deposits are buried many metres below.
They believe that the discovery offers a new way to locate the sought-after metal in difficult-to-reach locations.
Gold particles have been found around the soils of eucalyptus trees, but the researchers confirmed that the plants were taking in the element.
The researchers said the technique could also be used to find other minerals such as iron, copper and lead in other parts of the world.
