The results extend mineralisation at the Howards, Heron South, and Melbourne Bitter prospects, strengthening the potential for significant resource growth. Reasoning: Strong RC drilling results across three prospects \(Howards, Heron South, Melbourne Bitter\) confirmed mineralisation continuity and provided high-grade intercepts, supporting upcoming resource updates. - Positive factor: strong gold intercepts - Positive factor: extension of mineralisation - Positive factor: resource growth potential - Positive factor: high-grade intercepts Facts used in scoring: 15 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drilling confirmed an 800-metre southern extension to known gold mineralisation at Howards. Evidence · text > drilling confirmed an 800-metre southern extension to known gold mineralisation **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The announcement discusses drilling results intended to support upcoming resource updates. Evidence · text > strengthening the potential for resource growth ahead of updated estimates ## Extracted facts Stored fact records: 15.
