The useful sand body is characterized by fine, homogeneous white sand, angular quartz grains, low compaction and favorable physical characteristics for development. The Belmonte deposit is characterized by a useful sand body with strong visual whiteness, homogeneous grain size and clear contrast against impure sand layers. The useful material is generally white, clean and visually distinct from the superficial impure sand, which tends to present darker grey or yellowish coloration and may contain organic matter. The impure material is mainly located in the superficial portion of the deposit, generally within the first meter. This was considered during sampling and reserve estimation, with the first meter of drilling being discarded where appropriate to avoid contamination. Below this superficial layer, the useful sand is described as visually homogeneous across different drill holes, supporting the interpretation of continuity within the sand body. The useful sand has fine and homogeneous granulometry, with irregular and angular quartz grains. Under magnification, grains range from translucent to transparent, with occasional fine milky quartz gravel and rare well-formed hyaline quartz crystals. The material is described as very white and pure, with rare grey or yellowish material. After manual washing and drying, color differences were not significant. Physical characteristics such as low compaction, high porosity and favorable sand body morphology support the interpretation of a potentially attractive deposit for industrial development. These characteristics, combined with the chemical and granulometric results, strengthen the technical basis for the project. Key Technical Points: - White, clean and visually homogeneous useful sand - Superficial impure layer generally up to approximately 1.0 m - Fine and homogeneous grain size - Irregular and angular quartz grains - Low compaction and favorable porosity - Clear field contrast between useful white sand and impure yellowish clayey material
