Drill holes MBA-042 and MBA-043 returned wide, coherent gold intercepts, suggesting the system extends further west and at depth. Reasoning: The drilling confirmed a new, distinct porphyry body with significant width and continuity, extending the known mineralized system at Maria Bonita. - Positive factor: Discovery of a new mineralized porphyry body - Positive factor: Wide coherent mineralized intersections \(MBA-042 and MBA-043\) - Positive factor: Mineralization remains open to the west and at depth - Positive factor: Consistent gold grades observed - Negative factor: True widths not yet determined Facts used in scoring: 6 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drilling tested the western extension of the Maria Bonita porphyry system, confirming a new body. Evidence · text > tested the western extension of the Maria Bonita gold porphyry system **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 details assay protocols, including 50g fire assay, ICP atomic absorption, and use of blanks, standards, and duplicates. Evidence · text > inserting control samples randomly into the submitted batch, comprising field duplicates, independent reference samples and "blank" samples. **Apparent Width Only** Polarity: negative Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: The document explicitly states that true widths have not yet been determined. Evidence · text > True widths have not yet been determined. ## Extracted facts Stored fact records: 6.

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.
