## Minestarters Atlas summary

Critical Elements Lithium Corporation has announced the final assay results from its Winter 2026 drill program at the Rose West Discovery in Québec, reporting high-grade lithium, tantalum, and cesium intercepts. The program successfully expanded the mineralized footprint from 450m x 370m to 1,250m x 800m, demonstrating excellent lateral grade continuity and confirming the effectiveness of the geological model. Preparation is now underway for a follow-up Summer 2026 drilling program to continue this expansion.

Reasoning: Critical Elements reports high-grade lithium, tantalum, and cesium intercepts from its winter drill program at Rose West, successfully expanding the mineralized footprint and confirming lateral continuity. Several intercepts show exceptional lithium grades over significant widths, with notable tantalum and cesium values, particularly in hole RW-26-43.

## 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 explicitly states that quality assurance and quality control procedures were implemented, including the insertion of standards, duplicates, and blanks, and names ALS Minerals as the laboratory.

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.

**QP/CP Signed**

Polarity: positive

Story-specific tag

Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Why it applies: Kenneth Williamson, Géo, M.Sc. Director of Exploration at Critical Elements, is named as the Qualified Person who reviewed and approved the technical contents of the news release.

Evidence · text

> Kenneth Williamson, Géo, M.Sc. Director of Exploration at Critical Elements, is the Qualified Person that has reviewed and approved the technical contents of this news release on behalf of the Corporation.

**True Width Disclosed**

Polarity: positive

Definition: Actual thickness perpendicular to structure is stated, not just downhole length.

Why it applies: The document states that 'the true thickness is between 80 to 95% of the core length', providing a general range for true width.

Evidence · text

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

**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 450m x 370m to 1,250m x 800m, indicating step-out drilling.

Evidence · text

> The Phase 1 Winter 2026 drill program has delivered positive results demonstrating the successful expansion of the Rose West mineralized footprint from 450 m x 370 m to 1,250 m x 800 m

**Bonanza Intercept**

Polarity: positive

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

Why it applies: Hole RW-26-43 includes an intercept of 2,796 ppm Ta2O5 over 1.2m, which is an exceptionally high grade for tantalum.

Evidence · text

> including 2.28% Li 2 O, 2,796 ppm Ta 2 O 5 and 876 ppm Cs 2 O over 1.20 m

**Pegmatite Deposit**

Polarity: neutral

Story-specific tag

Definition: No canonical definition is currently available.

Why it applies: The project is described as a 'lithium-rich pegmatite bearing zone' and refers to 'spodumene-bearing pegmatitic bodies'.

Evidence · text

> Rose West is a near surface lithium-rich pegmatite bearing zone

## 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.
