. In areas where there is gold, significant quantities can be
recovered by cutting horsetails and burning them, and refining the ash.
I can't remember where I read that - or heard it, but I've never been
able to test the intelligence in the forty or more years I've had it in
the back of my mind. Either there is a plethora of horsetail and a lack
of gold in the area, or a fair amount of dispersed gold, but no sign of
horsetails.
See http://www.puralibre.com/html/eng_ho...l.html#History which says:
Horsetail absorbs gold dissolved in water better than most plants, as much
as 4 ounces per ton of fresh stalk".
Eh? Gold is soluble in water?! Here I was thinking it was inert...
That's a new one on me!
