# Canstar Resources Intersects Potential VMS Feeder Zone at Mary March - 118 m of Copper- and Zinc-Bearing Stringer and Disseminated Mineralization Within Intervals Totalling 270 m of Altered Rhyolite Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/canstar-resources-intersects-potential-vms-feeder-zone-at-mary-march-118-m-of-co--33e5fa65-38ad-410d-a99d-079974398387 Original source: https://money.tmx.com/en/quote/ROX/news/7198303840122846/canstar-resources-intersects-potential-vms-feeder-zone-at-mary-march-118-m-of-co Publisher: tmx Original announcement: 2026-07-08T11:45:00.000Z 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: Copper - Secondary commodities: Zinc, Lead - Document categories: Drill results, Agreement transaction - Extracted: 2026-09-18 18:31:33 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Canstar Resources has intersected a 118m zone of copper- and zinc-bearing sulphide stringers and disseminations in its first drill hole \(MM-26-41\) of the 2026 program at the Mary March VMS Project. The intercept is interpreted as a potential feeder zone within a large rhyolite package that shows strong stratigraphic similarity to the high-grade Buchans district. Assays are currently pending. Reasoning: The announcement reports a significant, wide intercept of base-metal sulphides in a highly prospective VMS feeder zone, supported by strong geological and geochemical evidence, though actual assay grades are pending. - Positive factor: Significant intercept of 118m of sulphide stringers/disseminations - Positive factor: Geological model supported by intersection of predicted rhyolite and basal contact - Positive factor: Independent litho-geochemical study confirms stratigraphy similarity to high-grade Buchans camp - Positive factor: Presence of copper and zinc sulphides confirmed by pXRF - Negative factor: Assays are still pending; current results are based on visual/pXRF only - Negative factor: True widths not yet determined Facts used in scoring: 3 ## Classification and evidence **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 118m interval is reported as a downhole/apparent width and true widths are not yet determined. Evidence · text > These are apparent widths; true widths and grades are not yet known. **Nearology Play** Polarity: neutral Definition: Value premise rests on proximity to a known deposit rather than own results. Why it applies: The project's value is heavily contextualized by its proximity and stratigraphic similarity to the historic Buchans mining camp. Evidence · text > The Buchans mining camp is well-known for producing some of the highest-grade VMS deposits in North American mining history. ## Extracted facts Stored fact records: 2.

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.
