The aim of this study is to reveal the horizontal and vertical positions of the existing mineralized structures in a small field in Gaziantep province, Sahinbey district, Ortaklar village. After reducing the total magnetic field data of the investigation field to the north pole (RTP), using the data obtained, horizontal gradient magnitude (HGM) and tilt angle map (TAM) techniques were used to investigate the locations of the mineralized structures. The high-amplitude contours of HGM and zero contour of TAM conform to lateral edges of the mineralized structures. Also, the depths of the mineralized structure were determined using the half of the horizontal distance between the +/- 45 degrees contours of TAM. Finally, the depth values found with the TAM technique were tested with the 2D inversion technique. For this, the data of the four profiles located at the high-amplitude anomaly locations in the first vertical magnetic gradient anomaly map are used to determine the depth of mineralized structures using the MAG 2D inversion program. The locations of the proposed drillings were determined between 20 and 30 m as a result of both TAM calculations using magnetic data and 2D inversion technique calculations using the first vertical magnetic gradient data.
