Au in its natural form, Au(0), is not ordinarily bio available and hence strategies to increase its solubility and bioaccumulation potential have been explored in the context of phytomining and phytoremediation applications. These include the use of lixiviates,e.g. cyanide, thiosulphate or thiocyanate, which aid solubilization and thus metal accumulation in plants [2]. Of these, Au complexes of cyanide are the most readily absorbed through the root membrane and hence the sampling of cyanide secreting plants is stressed if Au exploration is the objective
