Of the huge sum of money allocated to gold exploration, only a small proportion has been spent on geochemical surveys. A major reason for the lack of emphasis on geochemical methods lies in the unique geochemical characteristics of Au, namely the problem of sample representativity and analytical reproducibility caused by the uneven distribution of discrete Au particles in nature.
