What is Elucidating Pathfinding Elements from the Kubi Gold Mine in Ghana about?

X-ray photoelectron spectroscopy (XPS) and energy-dispersive X-ray spectroscopy (EDX) are applied to investigate the properties of fine-grained concentrate on artisanal small-scale gold mining samples from the Kubi Gold Project of the Asante Gold Corporation near Dunwka-on-Offin in the Central Region of Ghana. Both techniques show that the Au-containing residual sediments are dominated by the host elements Fe, Ag, Al, N, O, Si, Hg, and Ti that either form alloys with gold or inherent elements in the sediments. For comparison, a bulk nugget sample mainly consisting of Au forms an electrum i.e., a solid solution with Ag. Untreated (impure) sediments, fine-grained Au concentrate, coarse-grained Au concentrate, and processed ore (Au bulk/nugget) samples were found to contain cluster of O, C, N, and Ag with Au concentrations significantly lower than that of the related elements. This finding can be attributed to primary geochemical dispersion, which evolved from crystallization of magma and hydrothermal liquids as well as migration of metasomatic elements and rapid rate of chemical weathering of lateralization in secondary processes. The results indicate that Si and Ag are strongly conc
