## Minestarters Atlas summary

Pambili Natural Resources has completed due diligence on the London Wall gold project in Zimbabwe, identifying high-grade potential through metallurgical testing and historical mine plans. The company plans to re-equip the East Shaft for near-term production and conduct surface drilling to test the large-scale potential of the system.

Reasoning: The announcement reports promising metallurgical results \(8.87 g/t Au\) and identifies significant historical resource potential, though it explicitly notes the data is non-compliant and the metallurgical sample was hand-sorted.

- Positive factor: high-grade metallurgical results

- Positive factor: identification of large-scale potential

- Positive factor: near-term production potential at East Shaft

- Negative factor: historical resource is non-compliant

- Negative factor: metallurgical sample is non-representative \(hand-sorted\)

- Negative factor: requires significant rehabilitation/re-equipping

Facts used in scoring: 7

## Classification and evidence

**QA/QC Disclosed**

Polarity: positive

Story-specific tag

Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).

Why it applies: The release mentions a review by an independent geologist \(Gayle Hanssen\) who is a Qualified Person.

Evidence · text

> This news release has been reviewed by Gayle Hanssen... a qualified person as defined by Canadian National Instrument 43-101.

**Inferred Resource**

Polarity: negative

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

Why it applies: The historical resource estimate is described as non-compliant and lacks formal classification, implying high uncertainty.

Evidence · text

> The Historic Mine Plan contained a non-compliant resource estimate

gold

#### Identity

- Commodity: gold
- Ticker: PNN

#### Test Work

- Program Status: preliminary
- Test Type: metallurgical test
- Processing Route: gravity, CIL
- Sample: 18 kg sample recovered from illegal miner's stockpile at West Shaft

#### Recovery

- Recovery: 84.6 %
- Recovery Basis: actual\_test
- Head Grade: 8.87
- Head Grade Unit: g/t

#### Review

- Needs Review: No
- Historical: No

#### Dates

- Event date: 2025-05-15T00:00:00.000Z

Reasoning: 8.87 g/t is a high grade, but the company admits the sample was hand-sorted and likely higher grade than run-of-mine.

- Positive factor: high head grade

- Negative factor: non-representative sample \(hand-sorted\)

Evidence · text

> average gold assay results of 8.87 g/t and a carbon in leach \(“CIL”\) recovery rate of 84.6%

## 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.
