## Minestarters Atlas summary

ATEX Resources announced high-grade drill results from the Valeriano Copper-Gold Project in Chile, including 56m of 2.36% CuEq within a broader 592m interval of 1.04% CuEq in hole ATXD32, extending the B2B Zone 100m to the north. The Phase VI drill program is 80% complete and ahead of schedule. The company also provided details on its 2025 Mineral Resource Estimate, which includes 475 Mt Indicated at 0.88% CuEq and 1,511 Mt Inferred at 0.75% CuEq.

Reasoning: ATEX Resources announced new high-grade drill results from the Valeriano Copper-Gold Project, extending the B2B Zone mineralization by 100 meters to the north. The results include broad intervals of significant copper equivalent grades, with the drilling program progressing ahead of schedule, further validating the project's potential.

- Positive factor: Significant high-grade copper-gold-molybdenum intercepts

- Positive factor: Extension of high-grade mineralization along strike

- Positive factor: Drilling program ahead of schedule

- Positive factor: Large existing mineral resource estimate

- Negative factor: Qualified Person not independent of the company

- Negative factor: Lengthened assay laboratory turnaround times

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

Reasoning: A 124m intercept at 0.66% CuEq in the porphyry zone is a moderate result, indicating continued mineralization at greater depth.

- Positive factor: Long intercept length

- Positive factor: Moderate copper equivalent grade for a porphyry deposit

- Negative factor: Apparent width only, true width not stated

Reasoning: This is a historical intercept from Phase V, providing context for follow-up drilling but not new information. The grade and length are good for a porphyry deposit.

- Positive factor: Good copper equivalent grade

- Positive factor: Moderate intercept length

- Negative factor: Historical data, not new information

#### Review

- Needs Review: No
- Interp. Status: scored
- Historical: No

#### Dates

- Event date: 2026-02-12T00:00:00.000Z

Reasoning: Expanded from assay table. 2 g/t silver is weak against the default band \[500, 200, 100, 30\] g/t. Grade×width 248.0 g/t·m is weak \(grade alone is below; the better of the two is used\).

- Negative factor: Scored from rubric bands during table expansion, not from document context.

## 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.
