These results demonstrate potential for resource expansion and include both shallow and deeper mineralisation targets. Reasoning: New drill intercepts at Yannery and Austin prospects extend the known mineralised footprint outside the current Whundo resource, providing significant upside for a future resource update. - Positive factor: Step-Out Extension - Positive factor: Mineralisation outside existing resource Facts used in scoring: 8 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drill hits at Yannery and Austin are outside the current mineralised envelopes/resource. Evidence · text > returned copper-zinc-silver mineralisation outside Whundo’s existing resource ## Extracted facts Stored fact records: 8.

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.
