The 10,000m programme aims to de-risk the existing 10.6Mt Inferred Lithium Resource and the Medcalf West Exploration Target, funded by the recent sale of the Bynoe Lithium Project. Reasoning: The announcement focuses on the re-mobilisation of a second drill rig to advance an existing project rather than reporting new assay results. - Positive factor: re-commencement of drilling - Positive factor: fully funded programme - Positive factor: commitment to scoping study Facts used in scoring: 4 ## Classification and evidence **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The document references the existing Medcalf Lithium Resource and the ongoing drilling to de-risk it. Evidence · text > designed to test extensions and provide further infill at the 10.6Mt Medcalf Lithium Deposit **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: The primary resource mentioned is in the Inferred category.

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.
