## Minestarters Atlas summary

Lahontan Gold Corp. reported significant gold mineralization at the Santa Fe Mine Project, including a 3.25 g/t Au intercept in hole CAL26-03C. The results from Calvada Central and the South Slab Open Pit reinforce the project's resource potential as it advances toward 2027 construction.

Reasoning: The release reports high-grade gold intercepts from holes originally intended for geotechnical work, reinforcing the resource at Calvada Central, supported by robust QA/QC disclosure.

- Positive factor: High-grade gold intercept \(3.25 g/t Au\) in CAL26-03C

- Positive factor: Significant gold mineralization intercepted in geotechnical holes

- Positive factor: QA/QC protocols clearly disclosed with certified lab \(AAL\)

- Positive factor: Continuity of mineralization described as excellent

- Negative factor: True width is only estimated \(80-100% of drilled interval\)

Facts used in scoring: 6

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

Definition: Exceptionally high-grade zone, well above the deposit-type norm.

Why it applies: 3.25 g/t Au intercept in CAL26-03C is noted as high-grade for the deposit.

Evidence · text

> High grade gold mineralization grading 3.25 g/t Au \(116.7 – 118.1m\) in CAL26-03C

**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: Release includes detailed QA/QC protocols, including CRM and blank insertion rates and lab name.

Evidence · text

> Lahontan conducts an industry standard QA/QC program for its core and RC drilling programs.

**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 thickness is only estimated as a percentage of the drilled interval.

Evidence · text

> True thickness of the intercepts is estimated to be 80-100% of the drilled interval.

**Cut-off Disclosed**

Polarity: positive

Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: A current resource fact retains the disclosed cut-off grade

## 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.
