The trees don't have a biological need for the element, Lintern says; indeed, it may be toxic to them. "To the trees, gold may be just another heavy metal to be got rid of." Though the phytonuggets are too small to be collected and mined, they can serve as a sign that gold deposits may lie within the reach of a tree's roots.

Quartz is much more common than gold in nature, making it a popular sign of gold deposits and lodes. This mineral boasts a crystalline structure that is hard and composed of oxygen atoms and silicon. Since quartz mainly consists of silica ( Silicon Dioxide ), it has a natural tendency to trap heavy minerals and metals, such as gold.
