## Minestarters Atlas summary

Tres-Or Resources announced that Type II microdiamonds, which lack measurable nitrogen and are highly desirable, dominate samples from its Guigues Kimberlite pipe in Quebec. Of 17 microdiamonds tested by SRC, 14 were classified as Type II. This positive result, along with other geological indicators, is advancing the project towards macro-diamond tests.

Reasoning: The announcement reports that Type II microdiamonds, which are rare and highly desirable, dominate the samples from the Guigues Kimberlite pipe, indicating potential for high-value diamond occurrences. This is a significant positive indicator for the project's potential, although it is based on microdiamond analysis and does not guarantee the presence of larger stones.

- Positive factor: Dominance of highly desirable Type II microdiamonds \(14 out of 17 tested\)

- Positive factor: Lack of detectable nitrogen in Type II diamonds

- Positive factor: Testing conducted by a reputable laboratory \(SRC\) using industry-standard techniques

- Positive factor: Variability testing across different parts of the kimberlite pipe

- Negative factor: Results are from microdiamonds only, not macro-diamonds

- Negative factor: No guarantee that microdiamond results translate to large Type II diamonds

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

Facts used in scoring: 17

## Classification and evidence

**Type II Diamond Dominance**

Polarity: positive

Story-specific tag

Definition: No canonical definition is currently available.

Why it applies: 14 out of 17 microdiamonds lacked detectable nitrogen and are classified as Type II, which are rare and highly desirable.

Evidence · text

> In total, SRC reports 14 out of the 17 +0.150 mm microdiamonds lacked detectable nitrogen \(zero parts per million - 0 ppm\), and thus are the highly desirable Type II.

**Bench Scale Only**

Polarity: negative

Definition: Only preliminary bench tests completed — no locked-cycle or pilot work.

Why it applies: The microdiamond characterization was conducted at a lab scale using micro-Fourier Transform Infrared Spectroscopy \(FTIR\), not a pilot plant.

Evidence · text

> The nitrogen measurements were conducted by the Saskatchewan Research Council Geoanalytical Laboratories Diamond Services \(SRC\) on all Guigues +0.150 mm microdiamonds, using the industry-standard technique of micro-Fourier Transform Infrared Spectroscopy \(FTIR\).

**Multi-Domain Tested**

Polarity: positive

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

Why it applies: The 305 kgs of material processed comprised 3 samples from half-split drill core testing different parts of the pipe.

Evidence · text

> These Type II results are from microdiamonds recovered from 305 kgs of material processed at SRC for microdiamonds comprised of 3 samples from half-split drill core \(HQ size\) testing different parts of the pipe.

**Single Domain Only**

Polarity: negative

Definition: Testing limited to one composite or domain — representativeness not established.

Why it applies: only one composite was 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.
