## Minestarters Atlas summary

Spark Energy Minerals has reported a second discovery at its Arapaima Project in Brazil, identifying a new mineralized centre at the Boa Vista target. The maiden drilling returned project-record gallium grades of 114.3 g/t Ga2O3 and broad rare earth intervals, with mineralization appearing open in all directions.

Reasoning: Maiden drilling at Boa Vista target has identified a significant new gallium-rare earth-scandium mineralized centre with project-record gallium grades.

- Positive factor: Project-record gallium grade

- Positive factor: Maiden discovery of a second mineralized centre

- Positive factor: Broad rare earth intervals

- Positive factor: Presence of scandium

- Positive factor: Mineralization open in all directions

- Negative factor: True widths not known

- Negative factor: No metallurgical recovery demonstrated

Facts used in scoring: 5

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The company states the drill pattern has not closed off mineralization, providing potential to expand through step-out drilling.

Evidence · text

> providing clear potential to expand the mineralized footprint through step-out drilling

**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 use of blanks, field duplicates, and certified reference materials, and names an independent laboratory.

Evidence · text

> quality-control sample population comprised one blank at the start of each hole, one field duplicate per hole and two certified reference materials per hole

## 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.
