## Minestarters Atlas summary

Prospectiva Resources has reported initial assay results from its maiden exploration program at the São Francisco Copper-Gold Project in northeastern Brazil. The first three diamond drill holes intersected high-grade, near-surface copper mineralization, including 7.15 m at 4.78% Cu and a bonanza intercept of 0.75 m at 15.9% Cu. These results confirm geophysical anomalies and extend the known mineralization, suggesting a VMS-style system.

Reasoning: Initial drill results from the maiden exploration program at São Francisco delivered very high-grade, near-surface copper intercepts, confirming geophysical anomalies and extending mineralization along strike. The results suggest a VMS-style system with significant potential.

- Positive factor: High-grade copper intercepts

- Positive factor: Near-surface mineralization

- Positive factor: Maiden drill program success

- Positive factor: Confirms geophysical targets

- Positive factor: Potential VMS-style system

- Positive factor: QA/QC disclosed

- Positive factor: QP signed

- Positive factor: Step-Out Extension

- Negative factor: Apparent width only

- Negative factor: True width not established

Facts used in scoring: 24

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

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

Why it applies: The intercept of 0.75 m at 15.9% Cu in SF\_26\_003 is exceptionally high-grade for copper in a VMS-style deposit.

Evidence · table

> 15.9

Context: 0.75

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The drilling is systematically progressing eastwards to extend the zone of known mineralisation at SF1.

Evidence · text

> systematically drilling eastwards to extend the zone of known mineralisation at SF1

**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 details the QA/QC program including certified reference materials, blanks, and duplicate samples, and mentions review by a Qualified Person.

Evidence · text

> Prospectiva maintains a quality assurance and quality control \(QA/QC\) programme incorporating the insertion of certified reference materials \(CRMs\), blanks and duplicate samples into the analytical sample stream. QA/QC results are reviewed alongside the laboratory's internal quality-control data to assess the reliability of the analytical results. The Qualified Person has reviewed the available analytical results and associated QA/QC information to assess their suitability for public disclosure.

**Compositing Transparent**

Polarity: positive

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

Why it applies: The release states that significant intersections are calculated using a nominal lower cut-off grade of 0.20% Cu with no internal dilution applied.

Evidence · text

> Significant intersections are calculated using a nominal lower cut-off grade of 0.20% Cu. All reported intervals comprise contiguous samples exceeding the cut-off, with no internal dilution applied.

**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 release explicitly states that reported intervals are downhole lengths and true widths have not yet been established.

Evidence · text

> Reported intervals are downhole lengths; true widths have not yet been established.

**Cut-off Disclosed**

Polarity: positive

Story-specific tag

Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: The release clearly states a nominal lower cut-off grade of 0.20% Cu for significant intersections.

Evidence · text

> Significant intersections are calculated using a nominal lower cut-off grade of 0.20% Cu.

## 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.
