Abstract
Trace concentration of gold in the currrent thermal water from the Hishikari gold deposit has been determined by selective preconcentration using anion exchange, followed by inductively coupled plasma quadrupole mass spectrometry (ICP-MS). The concentration of gold in the Hishikari thermal water after filtration is extremely low, 0.6 ± 0.4 ppt. The low gold concentration suggests that the thermal water is at present not transporting gold and is not interacting with the gold deposits in the waning geothermal system of the Hishikari gold deposits.
