# 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-extractions.minestarters.com/news/altamira-gold-intersects-high-grade-gold-mineralization-within-the-cajueiro-mine--2ca4fc4e-9b97-4d5d-8ef4-9c1439c3de5e 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: 2026-09-13 11:15:17 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Altamira Gold reported high-grade gold drill results from the Cajueiro Central project in Brazil, including a 0.7m @ 19.0 g/t Au intercept. The results confirm mineralization extends beyond current resource boundaries and the company has commenced drilling at two new porphyry targets, Mombaque and Guillermo. Reasoning: Successful resource extension drilling with a bonanza-grade intercept \(19.0 g/t Au\) and expansion into new porphyry targets. - Positive factor: High-grade intercept of 19.0 g/t Au - Positive factor: Mineralization confirmed outside existing resource boundaries - Positive factor: Step-out drilling successful at Cajueiro Central - Positive factor: Commencement of drilling at new porphyry targets - Negative factor: Narrow widths on some high-grade intercepts 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 sector. Evidence · text > 0.7m @ 19.0g/t gold **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: CJO 114 was drilled outside the current resource and confirmed mineralization. Evidence · text > Hole CJO 114, drilled outside the current resource... confirming that mineralization extends beyond the existing resource boundaries. **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 QA/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 ## Extracted facts Stored fact records: 9.
