Here is the answer for Mexus... The only problem is that it involves another long delay AND there must be gold in order for it to work LOL
Geologists have discovered bacteria on a patch of earth in regional Queensland that takes natural traces of gold and turns them into nuggets.
Special ‘nugget-producing’ bacteria may hold the key to more efficient processing of gold ore, mine tailings and recycled electronics, as well as aid in exploration for new deposits, University of Adelaide research has shown.
For more than 10 years, University of Adelaide researchers have been investigating the role of microorganisms in gold transformation. In the Earth’s surface, gold can be dissolved, dispersed and reconcentrated into nuggets. This epic ‘journey’ is called the biogeochemical cycle of gold.
Now they have shown for the first time, just how long this biogeochemical cycle takes and they hope to make to it even faster in the future.
“Primary gold is produced under high pressures and temperatures deep below the Earth’s surface and is mined, nowadays, from very large primary deposits, such as at the Superpit in Kalgoorlie,” says Dr Frank Reith, Australian Research Council Future Fellow in the University of Adelaide’s School of Biological Sciences, and Visiting Fellow at CSIRO Land and Water at Waite.
“In the natural environment, primary gold makes its way into soils, sediments and waterways through biogeochemical weathering and eventually ends up in the ocean. On the way bacteria can dissolve and re-concentrate gold – this process removes most of the silver and forms gold nuggets.
“We’ve known that this process takes place, but for the first time we’ve been able to show that this transformation takes place in just years to decades – that’s a blink of an eye in terms of geological time.
