## Minestarters Atlas summary

Oroco Resource Corp. announced the fifth batch of assay results from its Phase 2 drilling program at the Santo Tomás copper project in Mexico, highlighted by 234.6 meters at 0.52% CuEq in hole S045. The results confirm and extend mineralization within the South Zone, supporting an expanded resource model and advancing the project towards a pre-feasibility study. The company also reported a high-grade polymetallic intercept in hole S050, though this style of mineralization is not currently planned for processing.

Reasoning: The drill results confirm and extend mineralization at the Santo Tomás project, with several wide, high-grade copper equivalent intercepts, supporting an expanded resource model and advancing the project towards a pre-feasibility study. A new style of polymetallic mineralization was also encountered, though not currently planned for processing.

## 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 states that "QA/QC protocols that include certified reference materials, blanks and duplicates" were followed.

Evidence · text

> QA/QC protocols that include certified reference materials, blanks and duplicates.

**Compositing Transparent**

Polarity: positive

Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals.

Why it applies: The document specifies that "Significant intervals are at least 10 m long and comprise samples that grade at least 0.15% Cu, but may include individual intervals of up to 4 m grading at least 0.05% Cu."

Evidence · text

> Significant intervals are at least 10 m long and comprise samples that grade at least 0.15% Cu, but may include individual intervals of up to 4 m grading at least 0.05% Cu.

**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 "All intervals are downhole lengths; true widths remain to be confirmed.".

Evidence · text

> All intervals are downhole lengths; true widths remain to be confirmed.

**PEA-Supporting**

Polarity: neutral

Story-specific tag

Definition: Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study.

Why it applies: The Phase 2 drilling program is designed to provide data for resource conversion and to "support pre-feasibility study \("PFS"\)-level mine planning", building on the existing PEA.

Evidence · text

> Phase 2 is designed primarily to provide the drilling density and technical data needed to evaluate the potential conversion of Inferred Mineral Resources to the Indicated category in the South Zone. The program is also collecting geotechnical, hydrogeological and metallurgical data to support pre-feasibility study \("PFS"\)-level mine planning.

**Compositing Transparent** — Rejected; excluded from scoring

Polarity: positive

Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals.

Reason: The document specifies that "Significant intervals are at least 10 m long and comprise samples that grade at least 0.15% Cu, but may include individual intervals of up to 4 m grading at least 0.05% Cu."

**Apparent Width Only** — Rejected; excluded from scoring

Polarity: negative

Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.

Reason: The document states that "All intervals are downhole lengths; true widths remain to be confirmed."

**Infill Drilling**

Polarity: neutral

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

Why it applies: drill\_program\_type is "resource"

**Nearology Play**

Polarity: neutral

Definition: Value premise rests on proximity to a known deposit rather than own results.

Why it applies: proximity is offered as the value premise: "MORE MINING NEWS Provenance Gold Provides an Update on the First Two Core Holes at Eldorado West, Encountering Numerous "

#### Rejected tags

**Refractory Ore** — Rejected; excluded from scoring

Polarity: negative

Definition: Ore requires oxidation/pressure treatment before recovery — a processing and recovery risk.

Reason: The document states that "There are currently no plans to process this style of mineralization", implying potential metallurgical or economic challenges.

Evidence · text

> There are currently no plans to process this style of mineralization

**QA/QC Disclosed** — Rejected; excluded from scoring

Polarity: positive

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

Reason: The release explicitly states that "QA/QC protocols that include certified reference materials, blanks and duplicates" were followed.

Evidence · text

> QA/QC protocols that include certified reference materials, blanks and duplicates.

**Compositing Transparent** — Rejected; excluded from scoring

Polarity: positive

Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals.

Reason: The document specifies that "Significant intervals are at least 10 m long and comprise samples that grade at least 0.15% Cu, but may include individual intervals of up to 4 m grading at least 0.05% Cu."

Evidence · text

> Significant intervals are at least 10 m long and comprise samples that grade at least 0.15% Cu, but may include individual intervals of up to 4 m grading at least 0.05% Cu.

**Apparent Width Only** — Rejected; excluded from scoring

Polarity: negative

Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.

Reason: The document states that "All intervals are downhole lengths; true widths remain to be confirmed."

Evidence · text

> All intervals are downhole lengths; true widths remain to be confirmed.

## 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.
