Summary
Black Canyon Limited has announced a maiden JORC 2012 compliant Mineral Resource Estimate for its Wandanya Project, totaling 23.6 Mt at 25.8% Mn and 12.5 Mt at 54.9% Fe. The estimate demonstrates high confidence, with over 90% of the manganese resource and 100% of the iron resource classified as Measured and Indicated. Initial metallurgical testwork indicates strong potential for high-quality beneficiated products and Direct Ship Ore (DSO) for both commodities, with a Scoping Study currently underway.
Reasoning: Black Canyon Limited announced a significant maiden JORC 2012 compliant Mineral Resource Estimate for its Wandanya Project, establishing a substantial, high-confidence resource base for both manganese and iron, supported by positive metallurgical testwork and shallow mineralization.
Positive factors
- Maiden Mineral Resource Estimate for both manganese and iron
- High confidence classification with over 90% of manganese resource in Measured and Indicated categories and 100% of iron resource in Measured category
- Significant grades for both manganese (25.8% Mn) and iron (54.9% Fe), including DSO potential
- Positive pilot-scale metallurgical testwork demonstrating high recoveries and product grades for manganese
- Shallow, near-surface mineralization amenable to open-pit mining
- JORC 2012 compliant estimate with Competent Person sign-off
Negative factors
- No production or reconciliation data available as it is a maiden estimate
- Further detailed metallurgical testwork is planned, indicating ongoing de-risking
- Elevated silicon in iron ore may be a penalty element
Low confidence — this extraction should be reviewed alongside the original source.

How Atlas produces this analysis
Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
