Rio Grande Heavy Mineral Sands Project

Location: Mostardas municipality, Brazil | Ownership: 100% Liberty Metals Limited

The Rio Grande Project includes 12 neighbouring tenements covering 234 km² in the Mostardas municipality, on the coastal plain of Rio Grande do Sul, Brazil’s southernmost state. Ideally situated, the project is directly next to Rio Grande Mineração’s South Atlantic Project.

The project is located in the Rio Grande do Sul Coastal Plain, a large geological area renowned for its rich mineral deposits. The mineralisation model shows a typical coastal placer deposit, formed naturally when heavy minerals such as rutile, ilmenite, and zircon were eroded from the ancient igneous and metamorphic rocks of the Sul-Riograndense Shield. Rivers transport these sediments to the coast, where wave action, tides, and currents sort and concentrate the denser minerals along both ancient and current shorelines.

The resulting deposits are located near the surface, extend laterally, and have straightforward geology, making them highly suitable for low-cost, traditional open-cut mining methods, such as dredging.

The prospectivity of the Rio Grande Project is supported by the success of the nearby South Atlantic Project.

The extensive work carried out provides a strong and highly relevant blueprint for exploring and potentially developing the Rio Grande Project.
