In Australia, Gold Really Does Grow on Trees!
You won’t believe it when you read this – scientists have found gold growing on gum trees near Wudinnaon the Eyre Peninsula in Australia.
A team of CSIRO scientists discovered eucalyptus trees near the country town draw up tiny gold “nuggets” from the earth via their root system and then deposit the valuable metal on their leaves, bark and branches.
While scientists have found gold on trees before, it was never actually known how it got there.
CSIRO geochemist Dr. Mel Lintern, lead author of the multi-million dollar project, said the discovery could save mining and gold exploration companies “a lot of money”.
“If they’re able to sample the trees (for gold) in place of drilling, then they’re going to save some money,” he said.
“The other aspect about that of course is sampling the vegetation is more environmentally benign that digging big holes or drilling.”
While the latter comment is undoubtedly true, one can't help but hope that the powers that be don't become so fixated on this "environmentally sound" way of mining, that they stop doing the old, hard way altogether. Gold is needed for many applications, and we have the example of the energy industry seeking after the mirage of "green energy" at the cost of industry and human comfort (and lives of the elderly.)
But the idea of gold on trees is, of course, fascinating. When I was a kid in Portugal, the rumor was one could go to Brazil, sit under the "gold tree" and wait for the gold to fall in one's lap. (I think this was metaphorical, but as a kid I saw it literally.)
Apparently they were wrong. For the real gold, you'd have to go to Australia.
