Black Canyon confirms manganese DSO potential at Wandanya. The ASX-listed company received positive metallurgical testwork results from its Western Australian project, demonstrating the ability to produce low-cost direct shipping ore products for high-grade manganese oxide and iron. Crush and sizing tests confirmed very low concentrations of deleterious elements, with manganese content concentrated in coarser fractions suitable for density-based upgrading techniques. Previous heavy liquid separation testing achieved manganese concentrate exceeding 44%. Managing Director Brendan Cummins highlighted the project's simple geological model with widespread shallow mineralization, enabling low-cost mining operations. The proposed process flowsheet involves straightforward crush and screen methods for DSO products, with beneficiation techniques for lower and medium-grade material.
