Results confirm simple dense media processing yields industry-standard products. These findings support an upcoming scoping study for a dual-commodity operation and an August resource expansion drill program.
Black Canyon Limited ( (AU:BCA) ) has shared an update.
Black Canyon has completed Stage 4 pilot scale dense media separation testwork on blended Wandanya drill core, successfully upgrading feed grades of 32.4% and 29.4% manganese to high-grade concentrates of 41.0% and 38.5% manganese at a 2.8 g/cm³ density. The trials delivered manganese recoveries of around 80% with low penalty elements, confirming that simple dense media processing can generate products comparable to industry-standard manganese concentrates.
The integrated Stage 1–4 metallurgical program has demonstrated Wandanya’s amenability to producing multiple products, including DSO manganese at 42–44% Mn and beneficiated concentrates with high recoveries and low impurities, with scope to improve recoveries via fines processing. These results will feed into an upcoming scoping study for a dual commodity operation, while an RC drill rig is set to mobilise in August to expand resources, underscoring the project’s progress toward potential commercial development.
