The EDS microanalyses provide information about the chemical composition of the associated minerals sporadically present on the gold grain surface, mainly represented by quartz, feldspars and goethite. The chemical analyses provide (1) the gold and silver contents from two selected populations of gold particles with different grain size, (2) the estimation of their gold fineness (G.F.) (ranging between 961 and 969) and (3) the composition of the mineral associations in the gold grains.
