The Kharmagtai copper-gold project is located in Omnogovi Province, approximately 420km southeast of Ulaanbaatar. It is within the South Gobi porphyry copper province which hosts most of the known porphyry deposits in the South Gobi region of Mongolia, including the Oyu Tolgoi copper-gold operations (120km south), the Tsagaan Suvarga porphyry copper-molybdenum development (170km east) and Xanadu’s Oyut Ulaan porphyry copper-gold exploration project (260km northeast).
Kharmagtai License Map
Kharmagtai consists of multiple co-genetic gold-rich porphyry copper centres and tourmaline breccia pipes occurring within the Lower Carboniferous Kharmagtai Igneous Complex. Extensive exploration has to-date identified significant shallow high-grade porphyry copper-gold mineralisation within the Altan Tolgoi, Tsagaan Sudal and Zesen Uul prospects, which are located within a 700m radius of each other. The gold-copper porphyry systems identified at Zesen Uul, Tsagan Sudal and Altan Tolgoi may be connected at depth and therefore cogenetic.
A majority of the strongly mineralised porphyry complex lies under unexplored shallow post-mineral sediments. Porphyry mineralisation at Kharmagati is associated with widespread magnetite alteration and all the main prospects are associated with broad magnetic highs. A regional magnetic survey outlines numerous distinct circular magnetic anomalies in the vicinity of the Altan Tolgoi, Tsagaan Sudal and Zesen Uul prospects. The large licence area has only been partially explored and the potential for further discoveries remains high.
