Summary:

The Chapadão pit is located in the carbonated complex designated as Domo I (o Complex Catalão I), which belongs to the Igneous Province of Alto Paranaiba. The area is characterized by a weathering profile developed in an intrusive lithology which consists of five types of materials: fresh rock, altered rock, saprolite (two types), and lateritic soil cover.

Catalão I complex
The phoscorite-carbonatite complex Catalão I is an approximately 5 km diameter circular structure. Within this complex, rocks were concentrically emplaced, with a predominant carbonatitic rock core which is surrounded by phoscorites and in turn surrounded by silicate rocks, such as pyroxenite. The rock types are closely associated with the mineralisation in the complex with niobium mineralisation located in the core of the complex (in the phoscorite-carbonatite zone) which is in turn surrounded by high-grade phosphate mineralisation (phoscorite zone) followed by the outer low grade phosphate mineralisation (pyroxenite zone).

As such Complex I hosts both Niobium and Phosphate economically significant mineralisation.

Chapadão – Phosphate
Weathering processes generated a thick weathering cover that, on average, is 150m thick which typically contains the horizontal tabular mineralised zones which are very extensive. During the weathering process some layers were silicified due to the water table variation, resulting in hard material within the mineralised zone. Min ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

All mining operations is conducted by contractors via conventional truck and shovel open pit mining methods. Waste material from the pits is delivered through a series of haul roads to onsite waste dumps for storage at each of the current operations.

The Chapadão pit final pit design is 1.9-km long, 1.7-km wide, and 90-m deep. All mining to date has taken place in the upper zone of lateritic and saprolitic soils, targeting the oxidized ore. During the site visit it was noted that no history of instability or wall failures had occurred since the beginning of its operations. RPM noted that mine personnel performs daily visual inspections, which are documented in a check list form and stored in hard copy format.
