## Minestarters Atlas summary

Critical Elements Lithium Corporation announced high-grade assay results from its 10,000-metre drill program at the Rose West Discovery in Québec. The program successfully expanded the mineralized footprint from 450m x 370m to 1250m x 800m and identified three new spodumene-bearing pegmatitic bodies. Key intercepts include 3.11% Li2O over 7.40m and 2.75% Li2O over 3.00m, demonstrating excellent lateral continuity and high-grade lithium and tantalum mineralization.

Reasoning: The drill program at Rose West has yielded multiple high-grade lithium intercepts, significantly expanded the known mineralized footprint, and identified new pegmatite bodies, indicating strong potential for resource growth and continuity.

- Positive factor: High-grade lithium intercepts \(up to 3.11% Li2O\)

- Positive factor: Significant expansion of the mineralized footprint from 450m x 370m to 1250m x 800m

- Positive factor: Discovery of three new spodumene-bearing pegmatitic bodies

- Positive factor: Excellent lateral continuity of mineralization

- Positive factor: True thickness estimated to be 80-95% of core length

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

Facts used in scoring: 22

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

Definition: Exceptionally high-grade zone, well above the deposit-type norm.

Why it applies: Multiple intercepts exceed the exceptional threshold for lithium \(e.g., 3.11% Li2O, 2.75% Li2O, 2.61% Li2O\), indicating very high-grade zones.

Evidence · text

> 3.11% Li 2 O and 48 ppm Ta 2 O 5 over 7.40 m

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The drill program successfully expanded the mineralized footprint from 450 m x 370 m to 1250 m x 800 m, significantly extending known mineralization.

Evidence · text

> The Phase 1 Winter 2026 drill program has successfully expanded the Rose West mineralized footprint from 450 m x 370 m to 1250 m x 800 m

**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 details QA/QC procedures including insertion of standards, duplicates, and blanks, use of ALS Minerals laboratory, and QP sign-off.

Evidence · text

> Quality assurance and quality control procedures have been implemented to ensure best practices in sampling and analysis of the drill core samples. Standards, duplicate and blanks were regularly inserted into the sample stream. The drill core samples were delivered, in secure tagged bags to the ALS Minerals laboratory facility in Val-d'Or, Québec.

**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 document states 'Core length; the true thickness is between 80 to 95% of the core length' but does not provide a single calculated true width for any intercept.

Evidence · text

> \* Core length; the true thickness is between 80 to 95% of the core length.

## 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.
