## Minestarters Atlas summary

Madoro Metals has discovered a potential lithium-bearing pegmatite dyke swarm at its First Green Lithium property in Quebec. Initial surface grab sampling identified elevated lithium and pathfinder elements, with highly fractionated K/Rb ratios indicating significant potential.

Reasoning: The discovery of a highly fractionated pegmatite swarm is a significant exploration milestone, though the lack of specific assay grades and the extremely small sample size \(5 grabs\) limit immediate economic certainty.

- Positive factor: discovery of lithium-bearing pegmatite dyke swarm

- Positive factor: highly fractionated K/Rb ratios \(<160 and <60\)

- Positive factor: presence of pathfinder elements \(Rb, Cs, Be, Ta\)

- Positive factor: first-pass exploration success

- Negative factor: very limited sampling \(only 5 grab samples\)

- Negative factor: no specific lithium grades reported

- Negative factor: dense moss and tree cover limiting exposure

Facts used in scoring: 5

## 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 release mentions review and approval by a Qualified Person \(John Langton, P.Geo.\)

Evidence · text

> reviewed and approved by John Langton, P.Geo., who is a Qualified Person \(QP\)

**Nearology Play**

Polarity: neutral

Definition: Value premise rests on proximity to a known deposit rather than own results.

Why it applies: The property is located in a rapidly emerging lithium belt with large holdings by other companies.

Evidence · text

> within a rapidly emerging lithium belt where large mineral claim holdings have been assembled by Brunswick Exploration Inc.

## 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.
