## Minestarters Atlas summary

Savannah says phase one of the Mutamba pre-feasibility study in Mozambique has started and TZMI has been appointed to carry out that work. The company also says the 20tph pilot plant is being assembled and will support metallurgical and product test work by Rio Tinto. The document includes background on the Mutamba resource and consortium terms, but no new assay, resource or recovery results for this announcement.

Reasoning: The release is primarily a corporate/project progress announcement about commencing phase one of the Mutamba PFS, with some supporting resource and metallurgical context in the background. It is mildly positive because it advances the project and a consortium milestone, but it does not provide new technical results.

- Positive factor: Phase one of the Mutamba pre-feasibility study has commenced

- Positive factor: TZMI has been appointed to complete this phase of work

- Positive factor: The 20tph pilot plant assembly is well underway

- Positive factor: A 35% interest in the Mutamba Consortium is tied to PFS completion

- Negative factor: This announcement reports a study commencement, not completed study results

- Negative factor: No assays, grades, recoveries or resource numbers are disclosed for the main Mutamba update

- Rubric flag: other vs resource\_update — Classify the document primarily as other because the main event is commencement of PFS work, with resource and metallurgy only as background context.

Facts used in scoring: 8

## Classification and evidence

**PFS-Supporting**

Polarity: neutral

Definition: Resource estimate prepared to support a Pre-Feasibility Study — requires adequate M&amp;I component.

Why it applies: The announcement states that phase one of the pre-feasibility study has commenced.

Evidence · text

> phase one of the pre-feasibility study \(‘PFS’\) ... has now commenced

**Resource Update**

Polarity: neutral

Definition: Revised estimate for an existing resource — compare to prior to assess progress.

Why it applies: The release restates the existing initial Indicated and Inferred Mineral Resource Estimate for Mutamba.

Evidence · text

> an established initial Indicated and Inferred Mineral Resource Estimate of 4.4 billion tonnes at 3.9% THM

**Theoretical Recovery Only**

Polarity: negative

Definition: Only theoretical or liberation-derived recovery reported, with no actual test result.

Why it applies: The pilot plant is said to provide product for metallurgical and product test work, but no actual recovery result is reported in this document.

Evidence · text

> provide product for metallurgical and product test work

**Mill Route**

Polarity: neutral

Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\).

Why it applies: the document describes a flotation route \("concentrate"\)

#### Tags used in scoring

**Inferred Resource**

Polarity: negative

Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.

Why it applies: category is "inferred"

**Cut-off Undisclosed**

Polarity: negative

Definition: High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: no cutoff\_grade was stated

**No Contained Metal**

Polarity: negative

Definition: Tonnage and grade reported but contained metal not calculated or disclosed — incomplete reporting.

Why it applies: contained\_metal was not reported

## 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.
