The survey results provide new structural targets for follow-up drilling to test for mineralization extensions. Reasoning: The seismic survey provides geophysical evidence that supports the continuity of the discovery zone, providing high-confidence targets for future drilling. - Positive factor: seismic survey identifies low-velocity anomalies correlating with known mineralization - Positive factor: targets identified for follow-up drilling - Positive factor: survey results consistent with previous drill program Facts used in scoring: 4 ## Classification and evidence **QA/QC Disclosed** Polarity: positive Story-specific tag Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The release mentions that the survey was subject to field quality-control procedures and reviewed by a Qualified Person. Evidence · text > Survey data were subject to field quality-control procedures **QP/CP Signed** Polarity: positive Story-specific tag 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: Robert Marvin, P.Geo., a Qualified Person, has reviewed and approved the technical information. Evidence · text > Robert Marvin, P.Geo., a Qualified Person as defined by NI 43-101, has reviewed the survey methodology ## Extracted facts Stored fact records: 4.

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.
