[QUOTE="user 4386, post: 657795, member: 4386"] I have never encountered alluvial silver - probably almost unknown (if not unknown). Some try and flog alluvial silver nuggets on ebay, but I suspect they are not truly alluvial if even natural (silver oxidises too rapidly in the atmosphere or streams). Best not to return amalgam or mercury into the creek (gets into fish - e.g. should not eat too many from Eildon reservoir). I realise the amount you found was insignificant, especially compared to the amount lost in creeks during the goldrushes (90 tonnes in Victoria)? Does less damage in garbage in principle though. Although metallic mercury is poisonous it is not extremely toxic unless swallowed, amalgam probably less so - methyl mercury is the real killer (and about a third of metallic mercury in streams will have converted to forms like methyl mercury since the goldrushes).
