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 porphyry body with significant width and continuity, extending the known mineralized footprint. - Positive factor: Discovery of a new mineralized porphyry body - Positive factor: Wide coherent mineralized intersections - Positive factor: Mineralization remains open to the west and at depth - Positive factor: Consistent gold grades - Negative factor: True widths not yet determined Facts used in scoring: 5 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drilling confirmed a new mineralized porphyry body to the west of the existing system. Evidence · text > confirming the presence of a new mineralized early porphyry body **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: The release details assay protocols, including blanks, standards, and duplicates, and names a commercial laboratory. Evidence · text > 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: 5. Some facts used in scoring do not have a stored record. ## Drill Results (5) ### MBA-042 [Link to this fact](https://atlas-staging.minestarters.com/news/altamira-gold-discovers-new-mineralized-porphyry-body-at-maria-bonita-west-cajue--e63b5d1c-ecaf-4cfd-851f-b1ab8e992169#fact-drill-facts-0) Maria Bonita West · gold #### Identity - Hole ID: MBA-042 - Project: Maria Bonita West - Commodity: gold - Region: brazil - Reported Region: Mato Grosso, Brazil - Ticker: ALTA.V #### Geometry - Grade: 0.4 - Grade Unit: g/t - Intercept: 36.2 m - From: 0 m - To: 36.2 m #### Classification - Deposit Type: porphyry - Program: exploration - Sample Type: drill - Group ID: MBA-042:0.0-36.2 - Mining Method: open\_pit #### QA/QC - Laboratory: SGS Geosol - QA/QC Disclosed: Yes - Lab Certified: Yes - QP Signed: Yes - QA/QC Methods: blanks, duplicates, standards #### Review - Needs Review: No - Interp.

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.
