## Minestarters Atlas summary

ATEX Resources announced drill results from its Valeriano Copper-Gold Project in Chile, extending the high-grade B2B breccia strike length to 600m and expanding the mineralized corridor by 200m to the east. Key intercepts include 70m at 0.99% CuEq in ATXD19A, 306m at 0.82% CuEq in ATXD26C, and a shallow 10m at 2.34% CuEq in ATXD35. These results confirm the continuity and expansion potential of the porphyry system, although average grades are below the project's prior best intercepts.

Reasoning: The drill results significantly extend the strike length of the high-grade B2B breccia and expand the broader mineralized corridor, demonstrating strong CuEq grades consistent with a porphyry system. While individual intercept grades are generally below the project's prior best average, the substantial step-out success and identification of new high-grade conduits indicate significant growth potential. The company's comprehensive QA/QC disclosure supports the reliability of the results.

- Positive factor: significant strike length extension

- Positive factor: expansion of mineralized corridor

- Positive factor: high-grade shallow intercept

- Positive factor: strong CuEq grades for porphyry deposit

- Positive factor: comprehensive QA/QC disclosure

- Negative factor: true widths unknown

- Negative factor: average grades below prior best intercepts

Valeriano Copper-Gold Project · copper

#### Identity

- Hole ID: Incl.
- Project: Valeriano Copper-Gold Project
- Commodity: copper
- Region: chile
- Reported Region: Atacama region of Chile
- Ticker: ATX

#### Geometry

- Grade: 0.45
- Grade Unit: %
- Intercept: 52 m
- From: 1580 m
- To: 1632 m

#### Classification

- Deposit Type: porphyry
- Sample Type: drill
- Group ID: Incl.:1580-1632
- Mining Method: open\_pit

#### Review

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

#### Dates

- Event date: 2026-05-26T00:00:00.000Z

Reasoning: Expanded from assay table. 0.45 % copper is strong against the porphyry deposit band \[0.8, 0.4, 0.25, 0.15\] %. Grade×width 23.4 %·m is weak \(grade alone is strong; the better of the two is used\).

- Positive factor: 0.45 % copper is strong on the porphyry deposit band.

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

Valeriano Copper-Gold Project · silver

#### Identity

- Hole ID: Incl.
- Project: Valeriano Copper-Gold Project
- Commodity: silver
- Region: chile
- Reported Region: Atacama region of Chile
- Ticker: ATX

#### Geometry

- Grade: 1.7
- Grade Unit: g/t
- Intercept: 52 m
- From: 1580 m
- To: 1632 m

#### Classification

- Deposit Type: porphyry
- Sample Type: drill
- Group ID: Incl.:1580-1632
- Mining Method: open\_pit

#### Review

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

#### Dates

- Event date: 2026-05-26T00:00:00.000Z

Reasoning: Expanded from assay table. 1.7 g/t silver is below against the default band \[500, 200, 100, 30\] g/t. Grade×width 88.4 g/t·m is below.

- Negative factor: 1.7 g/t silver is below the weak threshold \(30 g/t\) on the default band.

- 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.
