# Bonterra Intersects High-Grade, Visible Gold at O'Brien East Deep Target at its 100% Owned Desmaraisville South Project Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/bonterra-intersects-high-grade-visible-gold-at-o-brien-east-deep-target-at-its-1--e41e0431-eca0-42f6-b2bb-ef7c060ea0c2 Original source: https://www.newsfilecorp.com/release/314277/Bonterra-Intersects-HighGrade-Visible-Gold-at-OBrien-East-Deep-Target-at-its-100-Owned-Desmaraisville-South-Project Publisher: newsfile Original announcement: 2026-09-15T10:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Bonterra Resources Inc. - Ticker: BTR - Exchange: Unavailable - Region: Quebec - Primary commodity: Gold - Secondary commodities: None reported - Document categories: Drill results - Extracted: 2026-09-15 10:19:02 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Bonterra Resources has reported preliminary 2026 drill results from its Desmaraisville South Project in Quebec, highlighting high-grade gold intercepts at the O'Brien East Deep and Céré-Murgor targets. Notable results include 16.03 g/t Au over 0.4 m in hole BRDS-26-114 and 4.05 g/t Au over 0.6 m in hole BRDS-26-128A. The program is part of an ongoing exploration campaign to test deep targets near the O'Brien intrusive. Reasoning: The release reports several high-grade gold intercepts, including a 16.03 g/t Au interval with visible gold, supporting the identification of new exploration targets. - Positive factor: High-grade gold intercepts with visible gold - Positive factor: QA/QC protocols disclosed with multiple certified labs - Positive factor: Discovery of new targets east of the O'Brien intrusive - Negative factor: Apparent widths reported without true width disclosure Facts used in scoring: 7 ## Classification and evidence **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 MSALABS and AGAT Laboratories, use of blanks, duplicates, and standards, and ISO-17025 accreditation. Evidence · text > Blanks, duplicates, and certified reference standards are inserted into the sample stream **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: 16.03 g/t Au is exceptionally high grade for this type of exploration target. Evidence · text > 16.03 g/t Au over 0.4 m \(visible gold\) **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 states that true widths are not yet known. Evidence · text > Reported intervals represent drilled core lengths; true widths are not yet known. ## Extracted facts Stored fact records: 7.

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.
