# Canstar Trenching Reveals up to 5% Copper, +30% Zinc in Early Bedrock Spot Analysis, Reveals Semi-Massive Sulphide in Footwall Mineralization Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/canstar-trenching-reveals-up-to-5-copper-30-zinc-in-early-bedrock-spot-analysis--5ab8a469-e7a0-4021-b47e-f4226b35a263 Original source: https://money.tmx.com/en/quote/ROX/news/7369738703126539/canstar-trenching-reveals-up-to-5-copper-30-zinc-in-early-bedrock-spot-analysis- Publisher: tmx Original announcement: 2025-10-16T11:25:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Canstar Resources Inc. - Ticker: ROX - Exchange: TSX - Region: Newfoundland - Primary commodity: Zinc - Secondary commodities: Copper, Lead, Gold, Silver - Document categories: Drill results, Agreement transaction - Extracted: 2026-08-26 06:52:23 UTC Narrative sentiment: 0.70 · Bullish ## Minestarters Atlas summary Canstar Resources reported encouraging trenching results at the Mary March project in Newfoundland, with pXRF spot analyses showing up to 30% zinc, 4% copper, and 3% lead. The trenching exposed semi-massive sulphides and potentially extends historic mineralization to the surface. Additionally, the company entered option agreements to acquire 29 mineral claims adjacent to the project. Reasoning: Trenching revealed high-grade base metal spot analyses and semi-massive sulphides, suggesting extension of historic VMS mineralization, though formal assays are still pending. - Positive factor: High-grade pXRF spot analysis - Positive factor: Semi-massive sulphide exposure - Positive factor: Extension of historic mineralization - Positive factor: Strategic land acquisition - Negative factor: pXRF results are preliminary and selective - Negative factor: Assay results pending Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 10 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Trenching potentially represents the up-dip extension of mineralization identified in 1999/2000. Evidence · text > potentially represent the up-dip extension of mineralization first identified in 1999/2000 **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: The release mentions that assay results from accredited laboratories will be reported and notes the pXRF calibration. Evidence · text > Assay results from accredited laboratories will be reported when available. ## Extracted facts Stored fact records: 10.

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.
