# Altamira Gold Intersects 395.5m @ 0.4 g/t gold in First Deep Drill Hole at Maria Bonita, Expanding Mineralized System, Cajueiro District, Brazil Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/altamira-gold-intersects-395-5m-0-4-g-t-gold-in-first-deep-drill-hole-at-maria-b--642a2f85-8a59-4b92-91e4-9811f4a2882a Original source: https://money.tmx.com/en/quote/ALTA/news/4916101023461352/altamira-gold-intersects-395-5m-0-4-g-t-gold-in-first-deep-drill-hole-at-maria-b Publisher: tmx Original announcement: 2025-10-15T11:30:00.000Z 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 05:28:10 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Altamira Gold reported significant drill results from its first deep hole at the Maria Bonita project, intersecting 395.5m at 0.4 g/t gold. The results demonstrate that the quartz porphyry mineralized system is considerably larger and deeper than previously estimated. Reasoning: The first deep drill hole \(MBA032\) successfully intersected a very wide \(395.5m\) mineralized interval, proving the porphyry system extends significantly at depth. - Positive factor: significant depth extension of mineralized system - Positive factor: remarkable continuity of mineralization - Positive factor: demonstrated porphyry system scale Facts used in scoring: 8 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: MBA032 is described as the first deep drill hole below the resource, extending the mineralized system at depth. Evidence · text > significantly extends the size of the mineralized porphyry system, particularly at depth **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 laboratory, certified references, and blanks. Evidence · text > Gold analysis has been conducted by SGS method FAA505... Analytical quality is monitored by certified references and blanks. ## Extracted facts Stored fact records: 8.

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.
