The proposed Dargues Gold Mine near Braidwood has ignited another
controversy over a new proposal to use cyanide on site to process the
extracted ore............
A cyanide extraction process is used to extract gold, and silver, from low grade ore.
As cyanide is highly poisonous its use is highly controversial and banned in many instances.
The mine is located at the headwaters of the Deua River which
provides 60 percent of the water supply to the coastal shire of
Eurobodalla.
