## Minestarters Atlas summary

Pinnacle Silver and Gold Corp. announced the first results from its underground drilling program at the El Potrero gold-silver property in Durango, Mexico, reporting high-grade intercepts including 59.2 g/t gold and 424 g/t silver over 1.07 metres with visible gold. The program successfully extended the known strike length of mineralization at the Pinos Cuates mine to at least 70 metres. Despite some challenges with core recovery and true width estimation for certain intercepts, the results are described as extremely encouraging and will be used to generate an internal resource estimate.

Reasoning: The initial underground drilling program at El Potrero delivered exceptional gold and strong silver grades, including visible gold, significantly extending the known strike length of mineralization. While QA/QC is robust, concerns regarding poor core recovery and the lack of true width for some key intercepts slightly temper the overall confidence.

- Positive factor: Bonanza grades for gold and silver

- Positive factor: Visible gold observed

- Positive factor: Significant extension of strike length

- Positive factor: First results from underground drilling program

- Positive factor: Strong QA/QC disclosure

- Negative factor: Poor core recovery in some holes

- Negative factor: Potential loss of fine-grained gold during drilling

- Negative factor: True width not provided for all significant intercepts

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

Facts used in scoring: 48

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

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

Why it applies: The intercept of 59.2 g/t Au over 1.07 metres is exceptionally high-grade, well above the typical thresholds for epithermal gold deposits.

Evidence · text

> 59.2 grams per tonne gold \(g/t Au\) and 424 grams per tonne silver \(g/t Ag\) over 1.07 metres

**Bonanza Intercept**

Polarity: positive

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

Why it applies: The intercept of 9.69 g/t Au over 13.18 metres represents an exceptional grade-width product for an epithermal gold deposit.

Evidence · text

> 9.69 g/t Au and 143 g/t Ag over a core length of 13.18 metres

**True Width Disclosed**

Polarity: positive

Definition: Actual thickness perpendicular to structure is stated, not just downhole length.

Why it applies: True width is explicitly stated for several intercepts, such as 0.49m for EPUG26019 and 1.36m for EPUG26021.

Evidence · table

> 0.49

Context: 0.75

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The drilling program successfully extended the known strike length of mineralization to the northwest by approximately 20 metres and to the southeast by up to 21 metres.

Evidence · text

> extended the known strike length of the mineralization to the northwest by approximately 20 metres

**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 technical results are reported in accordance with NI 43-101, a Qualified Person has reviewed and approved the information, and samples were analyzed by an ISO/IEC 17025:2017 accredited SGS laboratory with standard QA/QC procedures including certified reference materials and blanks.

Evidence · text

> The technical results contained in this news release have been reported in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects \("NI 43-101"\). Pinnacle has implemented industry standard practices for sample preparation, security and analysis given the stage of the Project. This has included common industry QA/QC procedures to monitor the quality of the assay database, including inserting certified reference material samples and blank samples into sample batches on a predetermined frequency basis.

**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: For many significant intercepts, including the highest-grade ones, the estimated true width is noted as 'Along strike', indicating that only apparent width is reported without a calculated true width.

Evidence · table

> Along strike

Context: 1.07

**Poor Core Recovery**

Polarity: negative

Story-specific tag

Definition: No canonical definition is currently available.

Why it applies: The document explicitly states that 'Oxidation and fracturing of the rock resulted in very poor core recoveries in some holes, locally averaging as low as 20%'.

Evidence · text

> Oxidation and fracturing of the rock resulted in very poor core recoveries in some holes, locally averaging as low as 20%

**Potential Gold Loss**

Polarity: negative

Story-specific tag

Definition: No canonical definition is currently available.

Why it applies: The presence of fine-grained visible gold combined with poor core recoveries suggests that 'it is likely that some of this is being washed away by the water used in drilling', potentially understating actual grades.

Evidence · text

> With the gold-silver being very fine grained \(50 to 80 microns as per the mineralogical studies reported on June 2, 2026 \), it is likely that some of this is being washed away by the water used in drilling.

**Infill Drilling**

Polarity: neutral

Definition: Confirmatory drilling to raise resource confidence, not new discovery.

Why it applies: The program's objective includes drilling 'closely spaced holes from with the historic mine workings to better understand the size, shape and average grade of the mineralized zones', which is characteristic of infill drilling.

Evidence · text

> more than 100 short, closely spaced holes from with the historic mine workings to better understand the size, shape and average grade of the mineralized zones

## 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.
