# Altamira Gold Intersects High Grade Gold Mineralization within the Cajueiro Mineral Resource and Commences Drilling at the Untested Mombaque and Guillermo Porphyry Targets, Brazil Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/altamira-gold-intersects-high-grade-gold-mineralization-within-the-cajueiro-mine--bf7c63af-0d23-4fb6-900a-11196c7ced9a Original source: https://money.tmx.com/en/quote/ALTA/news/6249490273886470/altamira-gold-intersects-high-grade-gold-mineralization-within-the-cajueiro-mine Publisher: tmx Original announcement: 2026-01-28T12:30:00.000Z 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, Resource update - Extracted: 2026-08-21 02:49:26 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Altamira Gold has reported high-grade gold drill results from the Cajueiro Central project in Brazil, including a 0.7m @ 19.0 g/t Au intercept that extends the known mineralized zone. The company is also commencing drilling at two previously untested porphyry targets, Mombaque and Guillermo. Reasoning: The release reports high-grade gold intercepts \(up to 19.0 g/t\) that extend the known resource and announces the commencement of drilling at new porphyry targets. - Positive factor: High-grade gold intercepts reported - Positive factor: Mineralization confirmed extending beyond existing resource boundaries - Positive factor: New untested porphyry targets being drill tested Facts used in scoring: 9 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: 0.7m @ 19.0 g/t gold is exceptionally high grade for the deposit type. Evidence · text > 0.7m @ 19.0g/t gold , representing the highest-grade primary intercept reported to date **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 laboratory \(SGS Geosol\), assay methods \(50g fire assay, ICP\), and QC protocols \(blanks, standards, duplicates\). Evidence · text > For all drilling, half core is submitted to SGS Geosol... Quality control of drillhole assays follows normal industry procedures of inserting control samples randomly **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Hole CJO 114 was drilled outside the current resource and confirmed mineralization extension. Evidence · text > Hole CJO 114, drilled outside the current resource... confirming that mineralization extends beyond the existing resource boundaries. **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: The resource estimate includes a significant Inferred component. Evidence · text > 12.66Mt @ 1.26 g/t gold for a total of 515,000 oz in the Inferred Resource category ## Extracted facts Stored fact records: 9.

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.
