## Minestarters Atlas summary

Sonoro Gold Corp. announced assay results from 26 drill holes at its Cerro Caliche gold project in Sonora, Mexico, revealing continued expansion of higher-grade gold mineralization. The drilling identified new mineralized zones at La Colorada and extended known mineralization at Diana, supporting the project's district-scale epithermal potential. Notable intercepts include 28.95m at 2.598 g/t Au and 47.24m at 1.552 g/t Au, with several higher-grade sub-intervals.

Reasoning: The drill results demonstrate significant expansion of high-grade gold mineralization in new and existing zones at the Cerro Caliche project, validating the company's exploration strategy and supporting the potential for a larger epithermal system.

- Positive factor: High-grade intercepts

- Positive factor: Expansion of mineralization

- Positive factor: New mineralized zones identified

- Positive factor: District-scale potential

- Positive factor: Good QA/QC disclosure

- Positive factor: QP signed off

- Positive factor: Transparent compositing

- Negative factor: True width not explicitly stated for individual intercepts

Facts used in scoring: 68

## Classification and evidence

**QA/QC Disclosed**

Polarity: positive

Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).

Why it applies: The release states that blanks, certified reference materials \(standards\), and duplicate samples are systematically inserted, and samples are sent to Bureau Veritas laboratories.

Evidence · text

> blanks, certified reference materials \(standards\), and duplicate samples are systematically inserted into the sample stream. Personnel from either Sonoro Gold Corp. or Bureau Veritas \(BV\) collect the samples directly from the drill site and transport them to BV’s sample preparation laboratory in Hermosillo, Sonora.

**QP/CP Signed**

Polarity: positive

Story-specific tag

Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Why it applies: Stephen Kenwood, P.Geo., is named as a Qualified Person within NI 43-101 and has approved the news release.

Evidence · text

> Stephen Kenwood, P.Geo., an Independent Director of Sonoro, is a Qualified Person within the context of National Instrument 43-101 \(NI 43-101\) and has read and approved this news release.

**Compositing Transparent**

Polarity: positive

Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals.

Why it applies: The cut-off grade used for compositing intervals is clearly stated as 0.13 g/t Au.

Evidence · text

> Mineralized intervals were composited using a nominal reporting cut-off grade of 0.13 g/t Au.

**Apparent Width Only**

Polarity: negative

Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.

Why it applies: True widths are estimated as a range \(60% to 90%\) for the entire program, not explicitly stated for individual intercepts.

Evidence · text

> True widths are estimated to represent approximately 60% to 90% of the reported drilled interval lengths.

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The drilling is described as 'continued expansion of higher-grade mineralization' and 'newly-identified mineralized zone at La Colorada', validating the decision to 'expand the north extension' at Diana.

Evidence · text

> continued expansion of higher-grade mineralization at Cerro Caliche

## 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.
