## Minestarters Atlas summary

Stuve Gold Corp. announced high-grade polymetallic drill results from its initial diamond drilling program at the Teresa/Coba SW property in Chile. The program successfully extended copper, gold, silver, and cobalt mineralization 240m southwest and to a depth of 175m. The company also engaged Red Cloud Securities for market-making services to improve share liquidity.

Reasoning: The document reports high-grade copper, gold, silver, and cobalt intercepts from an initial diamond drilling program, confirming the extension of mineralization at the Teresa/Coba SW property. The results are significant for an early-stage exploration program, with good QA/QC disclosure. However, the lack of true width disclosure and cut-off grades introduces some uncertainty.

- Positive factor: High-grade polymetallic intercepts confirm extension of mineralization

- Positive factor: Initial drilling program successfully identified significant mineralization

- Positive factor: QA/QC procedures are disclosed, including certified lab and QP sign-off

- Negative factor: True width not disclosed for intercepts, potentially overstating thickness

- Negative factor: No cut-off grade disclosed for compositing, reducing transparency

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

Facts used in scoring: 24

## 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 explicitly mentions QA/QC procedures, including sample handling, delivery to ALS prep-lab, and analysis by ALS in Lima, Peru, with review by a Qualified Person.

Evidence · text

> During the drilling program all samples were cut from the drill core using a diamond saw by experienced Stuve Gold staff under the supervision of Eric Hanson P. Geo, a qualified person within the meaning of National Instrument 43-101. Each sample, consisting of one half of the relative core interval selected, was bagged and sealed on site and delivered by Stuve Gold staff to the ALS prep-lab in La Serena for processing. ALS subsequently shipped a 30g sub-sample pulp to their laboratory in Lima, Peru where they were analysed for gold by fire assay pre-concentration, AA finish and 35 other elements, including copper, silver and cobalt, by the ICP technique following Agua Regia digestion.

**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: The document reports downhole intercept lengths without providing true width estimates or drill orientation relative to mineralization.

Evidence · text

> The high-grade drill hole intercepts are as follows: Hole From To Width Cu% Au g/t Ag g/t Co% COBA-21-01 92.6 98.71 6.11

**No Cut-off Disclosure**

Polarity: negative

Story-specific tag

Definition: No canonical definition is currently available.

Why it applies: The document reports drill intercepts but does not state the cut-off grade used for compositing the intervals.

Evidence · text

> The high-grade drill hole intercepts are as follows: Hole From To Width Cu% Au g/t Ag g/t Co% COBA-21-01 92.6 98.71 6.11

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The drilling confirmed the extension of mineralization 240m southwest and to a total depth of 175m, beyond existing workings.

Evidence · text

> The results from the five holes intersecting mineralization confirm the extension of significant copper, gold, silver and cobalt mineralization and a productive zone a further 240m southwest and to a total depth of 175m \(60m below the existing underground workings of the South \(secondary\) shaft\)

Reasoning: This intercept shows a moderate silver grade over a significant width in an initial exploration hole, contributing to the extension of mineralization. However, the lack of true width and cut-off grade disclosure reduces confidence in the reported interval's representativeness.

- Positive factor: Moderate silver grade over a significant width for an initial exploration hole

- Positive factor: Part of a program extending known mineralization

- Negative factor: True width not disclosed

- Negative factor: No cut-off grade disclosed

Reasoning: This included intercept shows a high cobalt grade, indicating a high-grade core within the broader mineralized zone. The lack of true width and cut-off grade disclosure remains a negative factor.

- Positive factor: High cobalt grade within a broader mineralized zone

- Positive factor: Confirms high-grade core within the intercept

- Negative factor: True width not disclosed

- Negative factor: No cut-off grade disclosed

#### Tags used in scoring

**No QA/QC Disclosure**

Polarity: negative

Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document.

Why it applies: qaqc\_disclosed is not true

**Cut-off Undisclosed**

Polarity: negative

Definition: High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: no cutoff\_grade was stated

## 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.
