Enhancing Iron Ore Delineation through Ground Geophysics on Near-Surface Deposits

Geophysics plays an important role in mineral exploration, offering valuable support for reducing drilling risks, guiding target definition, and improving understanding of orebody geometry. This work presents two case studies involving the use of ground geophysical methods: one aimed at characterizing a colluvial deposit in an inactive iron mine, and another focused on estimating the thickness of an iron-rich layer in a tailing reservoir. In both cases, the materials studied have high iron content, representing opportunities to increase production without the need to develop new mining fronts.
