Studies having been conducted since 1999 were aimed at understanding
the geochemical dispersion in order to find a wide-spaced
sampling method to delineate geochemical provinces and a detailed
geochemical sampling method for locating the ore bodies. The field experimental
results show that gold tends to be concentrated in the fine grained
soil fraction (−120 mesh, b 0.125 mm) at a depth of
150–300 mm. Powder diffraction analysis was applied to acquisition
of mineral compositions (Table 3).
