## Minestarters Atlas summary

Selkirk Copper has completed its Phase 1 drill program, totaling 52,288 metres, with 87% of holes intersecting mineralization. The company has also assumed responsibility for the Minto mine site in Yukon and is preparing for a potential restart in 2027. An updated Mineral Resource Estimate and PEA are expected by mid-2026.

Reasoning: The company completed a major 52km drill program with high success rates and discovered a new lens, while also assuming site control, though full assay results are not yet available.

- Positive factor: Successful completion of large-scale Phase 1 drill program

- Positive factor: High success rate with 87% of holes intersecting mineralization

- Positive factor: Discovery of new mineralized lens in Area 118

- Positive factor: High-grade intercepts reported in Minto North

- Positive factor: Assumption of site responsibility marks transition to restart planning

- Negative factor: Only 48% of Phase 1 assay results released to-date

- Negative factor: Significant portion of drill program results still pending

Facts used in scoring: 21

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Resource expansion drilling stepped-out along sub-horizontal mineralized lenses.

Evidence · text

## 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.
