Radio Magnetotellurics technique (RMT) was conducted in the northern most town of Sweden (Kiruna), a very prominent mining city as a result of the presence of vast mineral deposits. The basis of this survey was to model the multi-dimensional nature of the subsurface and also to detect the width of these electrically conductive structures over the survey location. The mineral deposits (anomalies) are as a result of the past tectonic activi- ties experienced by the research location . These conductive anomalies are good target for electromagnetic induction method. The RMT soundings was done using the RMT-F device[3]. Three RMT pro- files spanning an approximate total distance of 5 km was covered. Sound- ing stations spacing was 10 m and 20 m respectively.
