The program also tested a magnetic target, identifying IOCG-style magnetite alteration and significant iron mineralization. Reasoning: Maiden drilling successfully identified a new porphyry-style target in addition to the expected IOCG-style mineralization, expanding the project's geological potential. - Positive factor: unexpected porphyry-style mineralization - Positive factor: strong sulphide system - Positive factor: maiden drill program success - Negative factor: low individual copper grades Facts used in scoring: 13 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The results expand understanding of copper mineralization and provide a new target style. Evidence · text > The results from the drilling expand our understanding of the copper mineralization in the area. **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: Release includes details on field duplicates, standards, and blanks. Evidence · text > The QA/QC procedure for this drilling program utilizes field duplicates, standards and blanks ## Extracted facts Stored fact records: 13.
