## Minestarters Atlas summary

Pinnacle Silver and Gold Corp. provided an update on the El Potrero gold-silver project in Mexico, highlighting high preliminary gold recoveries of 95.1%. The company is advancing underground rehabilitation, submitting environmental permits, and conducting a second round of metallurgical testing to optimize the flowsheet.

Reasoning: The company is providing a comprehensive project update showing progress across metallurgy, permitting, and community relations, moving towards a production decision.

- Positive factor: High gold recovery \(95.1%\) from preliminary testing

- Positive factor: Robust head grades reported for metallurgical composites

- Positive factor: Progress on permitting and community agreements

- Positive factor: Transitioning to underground delineation drilling

- Negative factor: Requirement for powerline feasibility study

- Negative factor: Need to resolve land ownership technicality via new agreement

Facts used in scoring: 6

## Classification and evidence

**Mill Route**

Polarity: neutral

Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\).

Why it applies: The company is optimizing a flowsheet including gravity separation and leach tests for a plant.

Evidence · text

> determining the best parameters for processing will allow for the design of an efficient flow sheet

**QA/QC Disclosed**

Polarity: positive

Story-specific tag

Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).

Why it applies: The release names a Qualified Person \(Mr. Jorge Ortega, P. Geo\) and a Director \(Mr. David Salari, P.Eng.\) who have reviewed and approved the technical information.

Evidence · text

> Mr. Jorge Ortega, P. Geo, a Qualified Person... has reviewed, verified and approved for disclosure the technical information

**Gravity Route**

Polarity: neutral

Definition: Gravity separation forms a material part of the flowsheet.

Why it applies: the document describes a gravity route \("gravity"\)

**Multi-Domain Tested**

Polarity: positive

Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed.

Why it applies: 3 distinct composites were tested

## 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.
