The study area is located in the Bu Khang Southwest block uplift. It is a small part of Song Ca River structural zone, belongs to folded system of West Vietnam (Dovjikov AE, 1965);[6]. Northern boundary of SongCa River structural zone adjacent to PhuHoat zone by Chieng Village - Cuon Village deep tectonic fault. The current structural plan of this zone is a synclinore complex with it's axis Northwest - Southeast. The major fault system dominates the scheme of the general structural zone is coincided with the general trend of it's structure. In the area there are some petro-tectonic assemblages such as: Lower - Middle Paleozoic assemblage, Upper Paleozoic assemblage, Lower Mesozoic assemblage, and Upper Mesozoic assemblage. During of geological mapping and mineral prospecting, geologists of Intergeo Division have discovered many different areas containing gold ores such as Tang Village - Na Quya, Huoi Co, etc; and gold-bearing ore zones has been initially preliminarily evaluated. Gold mineralization in the area with major mineralogical components are: pyrite, chalcopyrite, magnetite, galena, sphalerite, arsenopyrite, and native gold; gangue minerals are mainly quartz, calcite, sericite; secondary minerals are goethite, coveline, bornite, anglesite, and leucocen. The initial results of the study showed that the gold mineralization in Kim Son area, Nghe An province is hydrothermal origin, with the major phenomena wall-rock alteration such as quartzation, sericitation, chloritization, calcification, epidotization.
