Highlights
- Reverse circulation (RC) drilling at the W2 prospect has confirmed high-grade manganese mineralisation, supporting previous assays.
- The drilling program revealed consistent thickness and grade in manganese mineralisation.
- Follow-up mapping and rock chip sampling completed to further understand the new high-grade manganese deposit style.
- Initial metallurgical tests are planned to assess the feasibility of producing high-quality manganese concentrate for various applications.
Black Canyon Limited (ASX:BCA) has announced promising assay results from the reverse circulation (RC) drilling undertaken at the W2 prospect, part of the Wandanya Project. The maiden drilling program has revealed high-grade hydrothermal related stratabound manganese mineralisation, confirming earlier assays.
The most significant assay results include-
- 5m @ 31.1% Mn from surface, including 2m @ 42% Mn (WDRC005)
- 7m @ 28.3% Mn from 6m, including 5m @ 34.9% Mn (WDRC007)
- 7m @ 26.3% Mn from 2m, including 3m @ 38.2% Mn (WDRC013)
- 6m @ 26.3% Mn from 4m, including 3m @ 40.1% Mn (WDRC021)
- 6m @ 29.6% Mn from surface, including 3m @ 41.0% Mn (WDRC031)
- 6m @ 29.2% Mn from 4m, including 3m @ 39.7% Mn (WDRC032)
- 5m @ 32.4% Mn from 3m, including 3m @ 40.1% Mn (WDRC033)
Manganese Mineralisation at W2 Prospect
The 642m drilling program at the W2 prospect included 35 holes designed to analyse a target area measuring 240m long and 200m wide. The drilling results indicated consistent thickness and grade of manganese mineralisation, with the mineralisation dipping shallowly to the east and remaining open.
To better understand and quantify this new style of high-grade, stratabound manganese deposit, the company has conducted follow-up mapping and rock chip sampling to support planned drilling programs.
Additionally, an initial metallurgical test is planned to evaluate the feasibility of producing a high-quality manganese concentrate from W2 for silico or ferro alloying as well as for high-purity manganese sulphate (HPMSM) testwork.
The W2 discovery aligns well with the large resources identified across the Balfour Manganese Field, as highlighted in the company update.
BCA shares last traded at AU$0.063 apiece on 7 November 2024.
