Estimation of potential of iron sand in the Eastern Coastal Area of Cilacap Regency, Central Java Indonesia based on the magnetic anomalies data has been carried out in March 2016 ─ October 2018. The research area covers five coastal areas, i.e. Widarapayung, Western Binangun, Eastern Binangun, Western Nusawungu, and Eastern Nusawungu. The results of the research which are acquired show that iron sand deposits are estimated to be discovered in all coastal areas, where the greatest potential is the Western Nusawungu Coastal and the smallest potential is the Eastern Nusawungu Coastal. The range of the local magnetic anomalies data of the Western Nusawungu Coastal area is -711,38 ─ 1701,84 nT, whereas the range of the local magnetic anomalies data of the Eastern Nusawungu Coastal area is -498,66 ─ 201,73 nT. The potential of iron sand is based on the range value of the local magnetic anomalies data of each research area, because the local magnetic anomalies data are directly assosiated to the magnetic properties of iron minerals.
