Wanna find Gold reserves under Earth?

Main Points:

Researchers have found that Eucalyptus trees (gum trees) can help in finding gold reserves under earth as these trees have the ability to move up the gold particles from the earth and deposit them in the leaves and branches.

Study Further:

Eucalyptus Trees:

These are tall evergreen trees having tough aromatic leaves and flowers in clusters and provide good timber, resin, and oil with medicinal properties. There are more than 600 species.

Present Research:

Researchers have found that Eucalyptus trees extract gold from the ground using their root systems and deposit them in the leaves and branches. These trees’ roots get water from deep under the earth and get gold with water. However, gold is toxic to the plant; it moves to the leaves and branches from where it is moved out of the plant.

Researchers used CSIRO’s Maia detector for x-ray elemental imaging at the Australian Synchrotron to locate and see the gold in the leaves.

Researchers have found that although there are tiny gold deposits in the leaves and branches of the trees but it could help in finding gold ore deposits buried up to tens of meters underground that could be up to 60 million years old. This finding of deposits could further be made effective with other techniques.

Researchers are of the opinion that these trees or such natural processes could also be used for detection of other metals such as zinc and copper.

Research Suggestions:

I have an idea for improving the gold finding technique. In another research, scientists found that ants and termites could help in finding gold under earth. So, combine the power of ants/termites with Eucalyptus trees to increase gold finding process.
