Arrow Minerals Limited (ASX:AMD) Announces High Alumina Recovery at Niagara Bauxite Project
Metallurgical Results
Arrow Minerals Limited (ASX:AMD) has achieved high alumina recoveries in its Niagara Bauxite Project in Guinea. The first metallurgical results show an average alumina recovery of 81% under low temperature digestion and 91% under high temperature digestion across all composite samples tested. Available alumina results range from 36% to 47% Al₂O₃ in high-grade material and 34% to 41% Al₂O₃ in typical resource-grade material.
Mineral Resource Update
The maiden Mineral Resource for the Niagara Bauxite Project totals 185Mt at 42.3% Al₂O₃, including higher-grade subsets of 138Mt at 44% Al₂O₃ and 48Mt at 48.2% Al₂O₃. These results indicate the bauxite is suitable for processing in a wide range of alumina refineries, with consistent low reactive silica levels averaging 1.5% for low temperature digestion and 2.1% for high temperature digestion.
Scoping Study
The metallurgical results underpin Arrow’s ongoing scoping study, which is scheduled for completion in June 2025. The study aims to target a low CAPEX starter operation, maximising cash margins by initially leveraging the high-grade subset of the Mineral Resource to achieve a price premium for higher quality product.
Executive Comments
Managing Director David Flanagan stated, “These strong results will drive the assumptions in our ongoing scoping study and show the potential to generate a high quality bauxite product.” He added, “The results reveal high recoveries and a product which will meet or exceed key market requirements and is highly saleable. This is expected to sustain continued strong interest from prospective customers and yield positive outcomes in the scoping study.”
