The emergence and expansion of remote sensing and geophysical tools in the field of mineral resource exploration in recent decades is a result of the importance of this industry. The studied area is located in the northeast of Niriz city and near the village of Ghori in Fars province. From the geological point of view, the units of the studied area are located in the Sanandaj-Sirjan zone with a general trend of northwest-southeast. Most of these units are composed of limestone units, sericite chlorite schist units, and amphibolite units In this research, ASTER images and ground gravimetric data were used to explore and identify promising areas for iron ore in the studied area. The results of telemetry surveys led to the identification and discovery of four anomalies A, B, C, and D with a north-west-south-east trend, and the results of terrestrial gravimetric surveys also led to the identification and discovery of five anomalies A, B, C, D, and E. By using the ground magnetometer polarized mapper in the studied area, the location of these anomalies was compared with each other in a precise way, a measurement accuracy check was done, and in the end, all the anomalies were identified and identified with one. The most important gravimetric anomalies identified are A' and C', which are related to two large masses of iron with a depth of more than one hundred meters in the central part of the studied area, which is confirmed by the results of drilling data.
