# Altamira Gold Intersects Additional Mineralized Porphyry outside the Maria Bonita Mineral Resource, Extending the Exploration Footprint within the Cajueiro District, Brazil Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/altamira-gold-intersects-additional-mineralized-porphyry-outside-the-maria-bonit--6f96c715-01ab-4e9d-bfc1-802fce4b17b6 Original source: https://money.tmx.com/en/quote/ALTA/news/4536147501356871/altamira-gold-intersects-additional-mineralized-porphyry-outside-the-maria-bonit Publisher: tmx Original announcement: 2026-05-12T11:29:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Altamira Gold Corp. - Ticker: ALTA - Exchange: TSX - Region: Mato Grosso, Brazil - Primary commodity: Gold - Secondary commodities: None reported - Document categories: Drill results, Other - Extracted: 2026-08-20 23:10:27 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Altamira Gold has reported successful scout drilling at the Maria Bonita project in Brazil, intersecting a 70.6m gold interval that extends the known porphyry system to the west. The results indicate a separate, early-stage porphyry body that is open for further exploration. Reasoning: Scout drilling \(MBA036\) successfully intersected a wide, mineralized porphyry interval 100m outside the existing Maria Bonita resource, demonstrating significant exploration upside and extension of the system. - Positive factor: Step-Out Extension - Positive factor: Discovery of new porphyry body - Positive factor: Continuity of mineralization to the west Facts used in scoring: 3 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Intercept lies 100m below and to the west of the previously estimated mineral resource. Evidence · text > This intercept lies 100m below and to the west of the previously estimated mineral resource **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 mentions SGS Geosol lab, use of blanks, standards, and duplicates. Evidence · text > For all drilling, half core is submitted to SGS Geosol... inserting control samples randomly... comprising field duplicates, independent reference samples and 'blank' samples. ## Extracted facts Stored fact records: 3.

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.
