**Cut-off Disclosed**

Polarity: positive

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

Why it applies: The Mineral Resource is stated at a cut‐off grade of $137.40 NSR, determined based on economic assumptions provided in Table 2.

Evidence · text

> Mineral Resources are stated at a cut‐off grade of $137.40 NSR, determined based on economic assumptions provided below.

**Resource Update**

Polarity: neutral

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

Why it applies: The document presents a new Mineral Resource Estimate for the Berenguela Silver-Copper- Manganese Project, following a current NI 43-101 mineral resource estimate published on December 4, 2025.

Evidence · text

> The Report presents a new Mineral Resource Estimate for the Berenguela Silver-Copper- Manganese Project

**PFS-Supporting**

Polarity: neutral

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

Why it applies: The report includes recommendations for further metallurgical and engineering work with the objective of completing a preliminary feasibility study during 2026.

Evidence · text

> recommendations for further metallurgical and engineering work with the objective of completing a preliminary feasibility study during 2026.

**Measured Resource**

Polarity: positive

Definition: Highest confidence category — tonnage, grade, shape well-established from closely-spaced drilling. Basis for Proven Reserves.

Why it applies: The resource estimate includes a Measured category of 8.49 Mt.

Evidence · table

> Measured

Context: 8.49

**Indicated Resource**

Polarity: positive

Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves.

Why it applies: The resource estimate includes an Indicated category of 43.06 Mt.

Evidence · table

> Indicated

Context: 43.06

**Inferred Resource**

Polarity: negative

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

Why it applies: The resource estimate includes an Inferred category of 14.33 Mt.

## 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.
