## Minestarters Atlas summary

Critical Elements Lithium Corporation announced positive assay results from its Phase 1 Winter 2026 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. Significant intercepts include 1.89% Li2O and 207 ppm Ta2O5 over 13.50m in hole RW-26-32, and 2.18% Li2O and 68 ppm Ta2O5 over 12.60m in hole RW-26-46, with true thicknesses estimated between 80% to 95% of core length.

Reasoning: The drill program successfully expanded the mineralized footprint and identified new high-grade lithium and tantalum pegmatite bodies, demonstrating strong exploration success and continuity. QA/QC is well-disclosed, and true width is estimated.

- Positive factor: High-grade lithium and tantalum intercepts

- Positive factor: Significant expansion of mineralized footprint

- Positive factor: Identification of new spodumene-bearing pegmatitic bodies

- Positive factor: Excellent lateral continuity demonstrated

- Positive factor: True width disclosed

- Positive factor: QA/QC procedures disclosed and QP signed off

- Positive factor: Bonanza grade lithium intercept \(2.61% Li2O\)

- Positive factor: Good intercept length \(6.35m\)

- Positive factor: True width disclosed \(80-95% of core length\)

- Positive factor: Discovery of new Pegmatite 5 body

## 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.
