Highlights

Stage 2 heavy liquid separation (HLS) testwork upgraded manganese content from 30% Mn to 35% Mn.

The upgraded product shows promise as a feedstock for high-purity manganese sulphate (HPMSM) and for alloy smelters.

This latest testwork builds on Stage 1 dense media separation (DMS), which yielded 32% Mn from the KR1 deposit.

Stage 1 DMS testwork reported manganese grades of 8% Mn and 31.3% Mn.

Black Canyon Limited (ASX:BCA) has reported progress in its metallurgical testwork, achieving an upgraded manganese concentrate grade during the second stage of heavy liquid separation (HLS) on samples from the KR1 deposit within the Balfour Manganese Field. The results indicate that stage two density-based beneficiation can enhance manganese content to 35% from approximately 30%.

The company emphasises that this high-grade manganese product is promising for use as a downstream feedstock for high purity manganese sulphate (HPMSM) processing and has potential as a concentrate feed for manganese alloy smelters, subject to particle agglomeration.

This latest testwork builds on the first stage dense media separation (DMS), which yielded manganese concentrate grades of 32% Mn from the deposit.

BCA shares traded at AU$0.058 apiece on 24 September 2024.
