Investigation of iron ore mineral distribution using aero‐magnetic exploration techniques: Case study at Pocheon, Korea

Abstract

We present our aeromagnetic survey results from an investigation of the iron ore mineral distribution in Pocheon, Korea, in the west‐central area of the Korean Peninsula. A manned aero-magnetic system using a helicopter for regional exploration and an unmanned aeromagnetic system using a multicopter for high‐resolution exploration were used for the survey. The inversion results of the magnetic data confirmed the possibility of the existence of a new iron ore body. Drilling was carried out based on inversion results and drilling revealed amphibolite including iron ore, as indicated by a strong magnetic response. The position and depth of the iron ore were consistent with the interpretation results of the magnetic data.
