## Minestarters Atlas summary

Blackrock Silver announced drill results from its Tonopah West project in Nevada, extending silver and gold mineralization 600 metres to the northwest. The program identified a new intrusive complex as a priority exploration target. Significant intercepts include 0.43 m of 1,114.4 g/t AgEq and 0.76 m of 1,036.6 g/t AgEq, with assays for 12 additional drillholes pending.

Reasoning: Blackrock Silver's drill results from the Tonopah West project demonstrate a significant 600-metre extension of high-grade silver and gold mineralization to the northwest, identifying a new intrusive target with bonanza-grade intercepts. While true widths are not precisely stated and some deleterious elements are noted, the overall results are highly positive for resource expansion and future exploration potential.

- Positive factor: Significant high-grade silver and gold intercepts, with several exceeding 500 g/t AgEq, including a bonanza intercept of 1,114.4 g/t AgEq over 0.43 m.

- Positive factor: Drilling extends mineralization 600 metres to the northwest, significantly expanding the known mineralized footprint.

- Positive factor: Identification of a new intrusive complex as a priority exploration target for silver and gold concentration.

- Positive factor: Comprehensive QA/QC procedures are disclosed, including certified lab, QP sign-off, and use of blanks, standards, and check assays.

- Positive factor: Metal equivalent assumptions are fully disclosed, providing transparency for the AgEq calculations.

- Negative factor: Intercepts are reported as downhole lengths, with true width estimated to be 40-65% of the interval, indicating apparent width only.

- Negative factor: Narrow intercept lengths, with most significant results being less than 2 metres.

- Negative factor: Mention of elevated arsenic and antimony in one hole \(TXC26-190\) indicates the presence of deleterious elements, which could pose processing challenges.

Facts used in scoring: 38

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

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

Why it applies: Several intercepts, including 1,114.4 g/t AgEq over 0.43 m, 1,036.6 g/t AgEq over 0.76 m, and 1,096.0 g/t AgEq over 0.49 m, are exceptionally high-grade, well above the deposit-type norm for epithermal silver.

Evidence · table

> 1,114.40

Context: 0.43

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The NW Step Out Program drilling extends the inner mineralized high-grade corridor an additional 600 metres northwest along the projection of the Denver vein system.

Evidence · text

> 600-metre northwest extension: NW Step Out Program drilling extends the inner mineralized high-grade corridor an additional 600 metres northwest along the projection of the Denver vein system.

**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 includes a detailed 'Quality Assurance/ Quality Control' section, mentioning supervision by project geologists, strict chain of custody, use of American Assay Laboratory \(AAL\), and insertion of blanks, standards \(certified reference material\), and data verification.

Evidence · text

> All sampling is conducted under the supervision of the Company’s project geologists, and a strict chain of custody from the project to the sample preparation facility is implemented and monitored.

**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 states that 'True thickness is 40 to 65% of interval thickness based on the modelled vein geometries' rather than providing a specific true width for each intercept.

Evidence · text

> True thickness is 40 to 65% of interval thickness based on the modelled vein geometries

**Deleterious Elements Present**

Polarity: negative

Definition: Penalty elements \(arsenic, antimony, etc.\) or refractory concerns noted in the release.

Why it applies: Drillhole TXC26-190 intersected altered limestones carrying elevated arsenic and antimony, indicating the presence of penalty elements.

Evidence · text

> It bottomed at 1,383 metres in altered Palmetto Group limestones carrying elevated gold, arsenic and antimony at the volcanic contact.

Reasoning: Moderate silver equivalent grade over a very narrow width, confirming mineralization extension in the NW Stepout Program.

- Positive factor: Intercept contributes to the 600-metre northwest extension of mineralization.

- Negative factor: Very narrow intercept length \(0.34 m\).

- Negative factor: Silver equivalent grade is below the 75th percentile for epithermal silver deposits \(165 g/t AgEq\).

- Negative factor: True width is not precisely stated, only estimated as 40-65% of interval thickness.

## 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.
