[QUOTE="jethro, post: 605369, member: 1297"] As they aren't actually mining' just prospecting to define a resource they will (should) not be contaminating the surface water. Arsenic becomes a problem when orebodies are accessed and drained to the surface, or tailings from processing of these ores containing arsenic minerals ( principally Arsenopyrite ) are exposed to O2 in air or water and break down and oxidize. Elevated Arsenic levels that occur in surface samples of water or soil are considered a good indicator of gold ore bodies nearby as the two are usually associated. The orebodies within the Cassilis / Bethanga gold belt in North eastern Victoria all contain a complex mix of metal sulphides containing Iron, Arsenic, Lead, Copper, zinc, bismuth, antimony, etc etc. There is an Australian company called CleanTec that designs systems to treat mine waters by ionic exchange. They have recently commissioned a treatment plant at the largest vic gold producer at Fosterville near Bendigo. Im no geochemist so will be quite happy to be corrected by those more qualified.
