Mineral exploration is the underlying theme of industry and discoveries because humans have been exploring for minerals from the very beginning, based on their needs. This research aims to find promising areas of iron ore mineralization in Chak-Chak Exploration area of Yazd province, Iran. The study’s range lies at a latitude of 32-33 degrees north and a longitude of 54-55 degrees east. This study collected data using terrestrial magnetometry at 6222 points in a 20 m x 10 m grid. Initially, these data were pre-processed, such as removing the magnetic field effect of the Earth's core. Subsequently, processes such as applying polarisation filters, trend surface correction, upward and downward conversions, vertical derivatives and analytical signals on the terrestrial magnetic data were performed. The Exploration range contains numerous peaks in the southwest and other summits in the northeast, according to the research findings. These anomalies are consistent with igneous rock units (rhyolites) and faults. Consequently, it may be stated that one of the most rapid and least costly methods of detecting iron anomalies is terrestrial magnetism, which produces satisfactory results.
