The update reflects a reduction in total lithium carbonate equivalent \(LCE\) tonnage from 21.68 Mt to 15.08 Mt, driven by the strategic expiration of non-core mineral licenses to reduce annual fees. Reasoning: The resource estimate shows a significant tonnage decline \(approx 28%\) due to strategic reduction in license holdings, though grades remain high and the project remains a large-scale inferred resource. - Positive factor: high grade - Positive factor: QP/CP Signed - Negative factor: Tonnage Decline - Negative factor: Inferred Resource Facts used in scoring: 3 ## Classification and evidence **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: The entire resource is classified as inferred. Evidence · text > 15,082,000 tonnes of inferred LCE **Tonnage Decline** Polarity: negative Definition: Resource tonnage decreased vs prior estimate — pit optimization removed marginal material or geological model revised down. Why it applies: Total LCE tonnage decreased from 21.68 Mt to 15.08 Mt due to license reductions. Evidence · text > originally reported 21,681,000 tonnes of inferred LCE... The updated... totals 15,082,000 tonnes **QP/CP Signed** Polarity: positive 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: Alex Haluszka P. Geo. is named as the Qualified Person who reviewed and approved the estimate. Evidence · text > reviewed and approved by Alex Haluszka P. Geo. of Montrose Environmental Solutions Canada Inc. **Cut-off Disclosed** Polarity: positive Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison. Why it applies: The resource estimation was completed using a cut-off of 50 mg/L Li. Evidence · text > resource estimation was completed and reported using a cut-off of 50 mg/L Li ## Extracted facts Stored fact records: 3.

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.
