Key points
- Pilot plant study commenced to optimize niobium and rare earth recoveries
- 9 tonnes of saprolite material being used for the study
- Results expected in Q4 2026 to support the flotation flowsheet development
Full summary
St George Mining Limited is conducting pilot plant test work at its Araxá Project in Brazil to optimize the recoveries of niobium and rare earth elements (REE). The study, utilizing approximately 9 tonnes of saprolite material, aims to replicate the strong initial flotation test work results that produced high-grade niobium concentrate and rare earth-enriched tailings. The pilot plant, located at CIT-SENAI in Belo Horizonte, will conduct grinding, magnetic separation, and flotation processes. Downstream processing test work will target the production of ferroniobium from niobium concentrate and intermediate rare earth products from the tailings. The study is expected to conclude in Q4 2026, providing critical data for the development of the flotation flowsheet for potential mining operations at Araxá.
Guidance
Results from the pilot plant study expected in Q4 2026
Outlook
The pilot plant study aims to optimize recoveries and grades, supporting the development of the flotation flowsheet for potential mining operations at Araxá.
