## Minestarters Atlas summary

Jaguar Uranium Corp. announced a maiden Mineral Resource Estimate for its Laguna Salada Uranium-Vanadium Project in Argentina, reporting 4.2 million lbs of Indicated and 10.1 million lbs of Inferred U₃O₈, alongside 31.1 million lbs of Indicated and 57.3 million lbs of Inferred V₂O₅. The estimate, compliant with Regulation S-K 1300 and NI 43-101, highlights a large-scale, near-surface deposit with significant potential for resource expansion, covering only 4.3% of the project area. The company plans further work to upgrade inferred resources and expand mineralization.

Reasoning: The maiden Mineral Resource Estimate for the Laguna Salada project establishes a significant uranium-vanadium resource compliant with SEC S-K 1300 and NI 43-101, demonstrating large-scale, near-surface potential with substantial indicated and inferred categories and significant expansion potential, despite the U3O8-only grades being low.

- Positive factor: Maiden MRE

- Positive factor: Large scale

- Positive factor: Near-surface

- Positive factor: NI 43-101 Compliant

- Positive factor: SEC S-K 1300 Compliant

- Positive factor: QP/CP Signed

- Positive factor: Cut-off Disclosed

- Positive factor: Significant expansion potential

- Positive factor: Strategic critical minerals

- Negative factor: High proportion of inferred resources

- Negative factor: No Measured resources

- Negative factor: U3O8 grades alone are below typical economic cut-offs

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.
