## Minestarters Atlas summary

The 2026 Annual Report for Black Canyon Limited highlights significant progress at its 100%-owned Wandanya Manganese and Iron Project in Western Australia's Pilbara region. The company advanced Wandanya towards resource definition through extensive RC drilling, delivering consistent shallow, high-grade manganese and iron intersections. Metallurgical testwork demonstrated potential for Direct Shipping Ore \(DSO\) products and successful beneficiation to premium-grade manganese oxide concentrates. Additionally, the global Mineral Resource across the Balfour Manganese Field was updated to 315 million tonnes at 10.5% manganese, and a $10 million placement was completed to fund ongoing activities.

Reasoning: The annual report details substantial progress across all key operational areas, including a significant increase in global manganese resources, successful high-grade drilling at Wandanya, positive metallurgical results, and a well-received capital raise, indicating strong project advancement and de-risking.

- Positive factor: Significant global resource increase for manganese

- Positive factor: Category upgrade for KR2 resource

- Positive factor: Consistent shallow, high-grade manganese and iron drill intercepts

- Positive factor: Encouraging metallurgical testwork demonstrating DSO potential and high recoveries

- Positive factor: Successful capital raise to fund ongoing activities

- Positive factor: Low concentrations of deleterious elements in products

- Negative factor: Drill intercepts reported as apparent width only

- Negative factor: Metallurgical testwork is currently at bench scale \(HLS\)

Low confidence — this extraction should be reviewed alongside the original source.

#### Tags used in scoring

**QA/QC Disclosed**

Polarity: positive

Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).

Why it applies: qaqc\_disclosed is true

**Cut-off Undisclosed**

Polarity: negative

Definition: High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: no cutoff\_grade was stated

**Infill Drilling**

Polarity: neutral

Definition: Confirmatory drilling to raise resource confidence, not new discovery.

## 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.
