## Minestarters Atlas summary

Lupaka Gold Corp. announced encouraging sampling results from the newly developed 3430 sublevel at its Invicta Gold Development Project in Peru. The program returned an average of 9.22 g/t Au-Eq. over a 130-meter strike length with an average width of 4.2 meters, exceeding the estimated grade in the block model. The results demonstrate continuity of mineralization and suggest potential for more efficient mining, although the production decision is not yet based on a feasibility study.

Reasoning: The sampling program on the newly developed 3430 sublevel returned strong average gold equivalent grades, exceeding prior estimates and confirming continuity of the Atenea vein. Several individual samples show bonanza grades, and the geological observations suggest improved mining efficiency. QA/QC procedures are well-documented, supporting the reliability of the results.

- Positive factor: High-grade gold equivalent results from new sublevel

- Positive factor: Average grades exceed block model estimates

- Positive factor: Demonstrated continuity of mineralization along strike and up-dip

- Positive factor: Potential for more efficient mining and lower dilution due to merging veins

- Positive factor: Comprehensive QA/QC disclosure and accredited laboratory use

- Negative factor: PEA is preliminary and includes Inferred Mineral Resources

- Negative factor: Production decision not based on a feasibility study

- Negative factor: Intervals are apparent width only from channel sampling

Low confidence — this extraction should be reviewed alongside the original source.

Facts used in scoring: 39

## Classification and evidence

**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 analyses for this sampling campaign were carried out by ALS, an accredited laboratory, in Lima, Peru, exercising a thorough Quality Assurance and Control program \(QA/QC\). As part of QA/QC protocol, duplicates, standards and blanks were inserted into the sample processing stream.

Evidence · text

> The analyses for this sampling campaign were carried out by ALS, an accredited laboratory, in Lima, Peru, exercising a thorough Quality Assurance and Control program \(QA/QC\). As part of QA/QC protocol, duplicates, standards and blanks were inserted into the sample processing stream.

**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 'Width metres' for channel samples are apparent widths, and no true width is stated for individual samples.

Evidence · text

> Individual sample channels vary between 0.2 to 2.5 metres wide.

**Infill Drilling**

Polarity: neutral

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

Why it applies: The sampling program was conducted on a newly developed sublevel in preparation for the first block of mining production and to compare grades with the current Mineral Resource block model, indicating a resource definition purpose.

Evidence · text

> Development on the newly constructed 3430 sublevel was initiated in preparation for the first block of mining production \(located between the 3400 Level and the 3430 sublevel\)

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The results demonstrate continuity of the Atenea mineralization both up-dip from the 3400 Level and along strike, extending the known mineralization.

Evidence · text

> demonstrates the continuity of the Atenea mineralization both up-dip from the 3400 Level and along strike.

**Multi-Domain Tested**

Polarity: positive

Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed.

Why it applies: 2 distinct composites were tested

## 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.
