drillholes and 801 samples, with assays for Fe (iron), SiO₂ (silica), P (phosphorus), Al₂O₃ (alumina), Mn (manganese), CaO (calcium oxide), MgO (magnesium oxide) and TiO₂ (titanium dioxide). Neither drilling campaign recorded density measurements, and the project assumed that the tailings have an average density of 2.50 t/m³. Figure 2 – Distribution of drillholes 2.3 3D Geological Modeling The Gelado project as a whole covers 1,241 hectares. In this work, modeling was carried out specifically for Arm 1, Arm 2, and part of Arm 3, resulting in a study area of 778 hectares. The mineralized tailings body was modeled based on a total of 306 drillholes and 841 samples, with characterization of grades for Fe, SiO₂, Al₂O₃, Mn, CaO, MgO, TiO₂, and particle-size fractions of +0.250 mm, +0.150 mm, +0.106 mm, +0.075 mm, +0.045 mm, and −0.045 mm, using 25 × 25 × 5 m³ blocks and 3.125 × 3.124 × 0.5 m³ sub-blocks. The arms were modeled separately (Fig. 1). Figure 2 – Geological model
