## Minestarters Atlas summary

Lara Exploration has filed an independent NI 43-101 technical report for its Planalto Copper-Gold Project in Brazil. The report supports a maiden mineral resource estimate of 154 Mt at 0.36% Cu and 0.04 g/t Au, consisting of 47.7 Mt Indicated and 106.3 Mt Inferred resources.

Reasoning: The filing of a formal NI 43-101 technical report for a maiden resource provides significant de-risking and formalizes the project's scale, though the grades are relatively low and the resource is heavily weighted toward the Inferred category.

- Positive factor: Maiden resource established

- Positive factor: Significant tonnage reported

- Positive factor: QP/CP sign-off provided

- Positive factor: NI 43-101 compliant technical report filed

- Negative factor: Low grade copper

- Negative factor: High proportion of Inferred resource

Facts used in scoring: 8

## Classification and evidence

**Maiden Resource**

Polarity: neutral

Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. No prior estimate exists, so every change band is not applicable.

Why it applies: The technical report supports the initial resource estimate for the Planalto project.

Evidence · text

> supporting the initial resource estimate

**NI 43-101 Compliant**

Polarity: positive

Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard.

Why it applies: The technical report was prepared in accordance with NI 43-101 standards.

Evidence · text

> prepared in accordance with National Instrument 43-101

**QP/CP Signed**

Polarity: positive

Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Why it applies: Qualified Persons Leonardo de Moraes Soares and Michael Bennell are named and have signed off on the disclosure.

Evidence · text

> Qualified Person Mr. Leonardo de Moraes Soares MAIG, is a Qualified Person under NI 43-101

**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 report explicitly states the copper-equivalent cut-off grade used.

Evidence · text

> reported above a 0.16 % copper-equivalent cut off

## 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.
