Gold Found to Grow on Trees Above Ore Depositsselfnews Post Our scientists have revealed that gum trees from the Western Australian goldfields draw up tiny particles of gold via their roots and it ends up in their leaves and branches. The study published in Nature Communications today provides the first evidence of gold growing in trees. Eucalyptus leaves showing traces of different minerals. The eucalypt acts as a hydraulic pump its roots extend tens of metres into the ground and draw up water containing the gold. As the gold is likely to be toxic to the plant, its moved to the leaves and branches where it can be released or shed to the ground, CSIRO geochemist, Dr Mel Lintern says. Prospectors be warned the discovery is unlikely to start an old-time gold rush the nuggets are just one-fifth the diameter of a human hair and invisible to the eye. The leaves could be used in combination with other tools to get an idea of whats happening below the surface without the need to drill. It could enhance gold exploration in a way thats more targeted and environmentally friendly, says Dr Lintern. The research team used the powerful x-ray elemental imaging equipment at the Australian Synchrotron to locate and see the gold in the leaves.
