# Onyx Gold Discovers New High-Grade Vein Zone at the C Zone, Munro-Croesus Project Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/onyx-gold-discovers-new-high-grade-vein-zone-at-the-c-zone-munro-croesus-project--e93014ba-5c83-442b-bf52-e68def78d289 Original source: https://money.tmx.com/en/quote/ONYX/news/7658345596845198/onyx-gold-discovers-new-high-grade-vein-zone-at-the-c-zone-munro-croesus-project Publisher: tmx Original announcement: 2026-01-06T12:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Onyx Gold Corp. - Ticker: ONYX - Exchange: TSX - Region: Ontario - Primary commodity: Gold - Secondary commodities: Silver, Copper, Lead, Zinc - Document categories: Drill results - Extracted: 2026-09-18 15:09:00 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Onyx Gold has reported high-grade surface channel sampling results from the newly identified C Zone at the Munro-Croesus Project in Ontario. Highlights include an intercept of 124 g/t Au over 0.62 m, representing the highest-grade surface result to date for the project. The company is well-funded with $30 million in treasury to support an ongoing 75,000 m drill program. Reasoning: The discovery of a new high-grade vein zone with intercepts significantly exceeding the 75th percentile for orogenic gold deposits \(124 g/t vs 4.965 g/t\) represents a high-impact exploration milestone. - Positive factor: High-grade surface intercepts \(124 g/t Au\) - Positive factor: New high-grade vein zone identified - Positive factor: Fully funded 75,000 m drill program - Positive factor: QA/QC protocols and certified lab \(ALS\) disclosed Facts used in scoring: 4 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: 124 g/t Au over 0.62 m is exceptionally high-grade for an orogenic gold system. Evidence · text > 124 g/t Au over 0.62 m **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 ALS Geochemistry's ISO 17025 accreditation and the use of blanks, standards, and duplicates. Evidence · text > The Company maintains a robust QA/QC program that includes the collection and analysis of duplicate samples and the insertion of blanks and standards **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The C Zone is described as a new target within the broader Munro-Croesus Project. Evidence · text > The results from the C Zone underscore the potential for additional high-grade discoveries across the broader Munro-Croesus Project area ## Extracted facts Stored fact records: 4.

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.
