Abstract: The aim of this research was to use ground magnetic survey for exploration of new deposit in Taknar polymetal massive sulfide which is located in Northeast Iran in a tectonic corridor between two active faults. It is a syngenetic type mineralization formed at specific horizon within Taknar formation (Paleozoic?). Four mineralized zones named Tak 1, 2, 3 and 4 have been identified. Three style of mineralization such as layered, massive and stockwork have been recognized. Magnetite increases toward the massive part (up to 80 %), which is situated in the upper section. Magnetic susceptibility of the country rocks is 6x10-5 to 27x10-5SI, the stockwork mineralization is 4600x10-4SI, the layered is 7054x10-4 SI and massive is 1730x10-3SI. Due to this sharp magnetic contrast magnetic method found ideal and used for the identification of new deposit in Tak 1, 4 and outside of Tak 1 (to the east). Magnetic maps and images revealed distinctive anomalies on Tak 1, 4 and outside of Tak 1. The amplitude of the anomaly on Tak 1, 4 and outside of Tak 1 was 1500, 2227 and 1231 gamma respectively. The anomaly outside of Tak 1 is similar in magnitude to Tak 1 and does not have surface exposure. By analogy the source of all magnetic anomalies in Tak 1, 4 and outside of Tak 1 is magnetite present along with mineralization. Therefore the location of the anomaly outside of Tak 1 on the reduction to the pole map was proposed as drilling target
