Alluvial gold in some Southland valleys has recently been found to contain a high mercury content. Mercury sulphide (cinnabar, HgS) from hydrothermal veins (see map) is commonly found with alluvial gold in gravels. Dissolved mercury in streams is elevated above background but is lower than drinking water limits.
