## Minestarters Atlas summary

Cosa Resources has reported the first drill results of the winter 2026 season at the Murphy Lake North Project, intersecting 5.0 metres of anomalous radioactivity. The radioactivity was measured up to 13,900 CPS, though specific uranium grades were not disclosed.

Reasoning: The announcement reports anomalous radioactivity \(CPS\) from the first drill hole of the season, which is a positive exploration signal but lacks specific grade \(U3O8\) or hole identification for technical validation.

- Positive factor: first winter 2026 drill hole

- Positive factor: anomalous radioactivity intersected

- Negative factor: radioactivity reported in CPS rather than grade \(U3O8\)

- Negative factor: no specific hole ID or depth provided

Facts used in scoring: 1

## Classification and evidence

**Nearology Play**

Polarity: neutral

Definition: Value premise rests on proximity to a known deposit rather than own results.

Why it applies: The project is a joint venture with Denison Mines, a major uranium player, and results are described in the context of the Murphy Lake North Joint Venture.

Evidence · text

> MLN is a joint venture \(the "Joint Venture"\) between Cosa and Denison Mines Corp.

## 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.
