## Minestarters Atlas summary

Savannah reported new lithium drill results from the Grandao and Pinheiro deposits at the Mina do Barroso project in northern Portugal. The company highlighted several significant intercepts and said drilling is continuing to expand both deposits, with better grades at depth at Grandao. The release also includes a JORC table, QA/QC details, and metallurgical sample preparation notes.

Reasoning: The release reports new drill intercepts from the Mina do Barroso lithium project, with several significant intersections and evidence of continuity at depth. It also contains JORC disclosure and drill-method details, but the intervals are apparent widths only and the program remains exploration/resource-definition oriented.

- Positive factor: multiple lithium intersections reported at Grandao and Pinheiro

- Positive factor: drilling confirms continuity and grade increase at depth

- Positive factor: QA/QC and Competent Person disclosure included

- Positive factor: cut-off grade and internal dilution disclosed in JORC table

- Negative factor: results are downhole intercepts; true width not stated for the reported intervals

- Negative factor: one interval is noted as a twin hole for metallurgical purposes

- Negative factor: this is exploration/definition drilling, not a resource estimate

- Rubric flag: drill\_results deposit\_type — The release describes spodumene-bearing pegmatites, but the provided rubric does not include a pegmatite deposit style; deposit\_type was left as 'other'.

Facts used in scoring: 27

## Classification and evidence

**Infill Drilling**

Polarity: neutral

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

Why it applies: The release says the Grandao diamond drilling was aimed at infill drilling of deep sections and continuity of mineralisation for future mine planning.

Evidence · text

> The infill drilling was carried out to target the continuity of the west dipping pegmatite ore body at depth

**True Width Disclosed**

Polarity: positive

Definition: Actual thickness perpendicular to structure is stated, not just downhole length.

Why it applies: The release states the drill holes were oriented to get as close to true width as possible, though the reported table still presents downhole intercepts.

Evidence · text

> The drill holes were orientated at either -60 degrees or -90 degrees depending on the dip of the pegmatite in an attempt to get drill holes as close to true width as possible

**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 JORC appendix names ALS laboratories and describes blanks, certified reference standards and duplicates.

Evidence · text

> The samples were analysed using ALS laboratories ME-MS89L Super Trace method

**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: Both tables are reported using a 0.5% Li2O cut-off, and the appendix reiterates the weighted-average basis with no more than 2m internal dilution.

Evidence · text

> using a 0.5% Li2O cut-off

**Compositing Transparent**

Polarity: positive

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

Why it applies: The appendix states that high grade intercepts were weighted averages using a 0.5% Li2O cut-off with no more than 2m of internal dilution.

Evidence · text

> High Grade Intercepts are weighted averages using a 0.5% Li₂O cut off with no more than 2m of internal dilution

**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 reported intersections are downhole intercepts and the document says true width is only approached, not stated for the intervals.

Evidence · text

> Exploration results are reported as down hole intercepts

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The release says drilling continues to expand both the Grandao and Pinheiro deposits and that mineralisation is confirmed over significant strike lengths.

Evidence · text

> Drilling continues to expand both the Grandao and Pinheiro deposits

## 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.
