## Minestarters Atlas summary

Prospectiva Resources reported strong initial assay results from the first three holes of its maiden drilling programme at the São Francisco Copper-Gold Project in Brazil. The holes intersected high-grade copper, gold, and zinc mineralisation, with one intercept reaching 9.17% Cu.

Reasoning: Initial maiden drill results show very high-grade copper \(up to 9.17%\) and consistent mineralisation at shallow depths, supporting a VMS-style model.

- Positive factor: High-grade copper intercepts \(up to 9.17% Cu\)

- Positive factor: Consistent mineralisation across all three initial holes

- Positive factor: VMS-style stratabound system interpretation

- Positive factor: Near-surface discovery

- Positive factor: QA/QC protocols disclosed

- Negative factor: True widths not yet established

Facts used in scoring: 21

## 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: Release includes details on CRM, blanks, and duplicates, and names ALS as the laboratory.

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

**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 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.

## 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.
