## Minestarters Atlas summary

Silverco Mining Ltd. has commenced a 15,000-meter exploration drill program at its La Negra Project in Querétaro, Mexico, utilizing two rigs for surface and underground drilling. The program aims to test high-grade silver zones near existing mine infrastructure, building on a database of over 2,850 historical drill holes. While the release highlights significant historical assay results, no new drill results are presented.

Reasoning: Silverco has commenced a 15,000-meter exploration drill program at its 100% owned La Negra project in Mexico, targeting high-grade silver zones based on strong historical results, but this release does not include new assay results.

- Positive factor: Commencement of 15,000-meter exploration drill program

- Positive factor: Targeting high-grade silver zones near existing mine infrastructure

- Positive factor: Strong historical drill results provide exploration targets

- Positive factor: Established QA/QC protocols for the new drilling program

- Positive factor: Project is 100% owned

- Negative factor: No new drill results reported in this release, only historical data

- Negative factor: QA/QC protocols for historical drilling cannot be fully verified

- Negative factor: Intervals reported are downhole core lengths with no true width stated

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

Facts used in scoring: 108

## Classification and evidence

**Stale Data Re-release**

Polarity: negative

Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty.

Why it applies: The document presents 'Selected historical results' in Tables 1 and 2 as the primary data, rather than new assays from the current drill program.

Evidence · text

> Selected historical results are presented in Tables 1 and 2.

**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 'Standardized core logging protocols and QA/QC procedures have been established for the 2026 program, and drill core will be submitted for multi-element analysis, providing the geochemical dataset needed to vector toward silver-rich portions of the zoned skarn system.'

Evidence · text

> Standardized core logging protocols and QA/QC procedures have been established for the 2026 program

**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: The scientific and technical information has been reviewed and approved by Nico Harvey, P.Eng., Vice President Project Development of Silverco, a Qualified Person as defined in National Instrument 43-101.

Evidence · text

> The scientific and technical information contained in this news release has been reviewed and approved by Nico Harvey, P.Eng., Vice President Project Development of Silverco, a Qualified Person as defined in National Instrument 43-101.

**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: Note \(2\) explicitly states that 'Reported intervals are downhole core lengths,' indicating that true widths are not provided.

Evidence · text

> \(2\) Reported intervals are downhole core lengths.

Reasoning: Historical intercept of 18.3 m at 180.3 g/t silver \(344 g/t AgEq\) with associated gold, lead, and zinc in the Maravillas zone, representing an exceptional grade-thickness product over a strong width, but is historical data with unverified QA/QC.

- Positive factor: Moderate silver grade \(180.3 g/t\)

- Positive factor: Exceptional silver grade-thickness product \(3300.09 g/t·m\)

- Positive factor: Strong intercept width \(18.3 m\)

- Positive factor: Significant associated gold \(0.57 g/t\), lead \(2.50%\), and zinc \(2.30%\) grades

- Negative factor: Historical data with unverified QA/QC

- Negative factor: Apparent width only \(18.3 m\)

#### Tags used in scoring

**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: qaqc\_disclosed is 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

**Stale Data Re-release**

Polarity: negative

Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty.

Why it applies: the fact restates a prior release

## 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.
