# Coast Copper Highlights its Sweeney Silver Project and Congratulates Surge Copper Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/coast-copper-highlights-its-sweeney-silver-project-and-congratulates-surge-coppe--b859f068-e0ac-4889-9102-bc258812d929 Original source: https://money.tmx.com/en/quote/COCO/news/7000510838617461/coast-copper-highlights-its-sweeney-silver-project-and-congratulates-surge-coppe Publisher: tmx Original announcement: 2026-03-02T14:12:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Coast Copper Corp. - Ticker: COCO - Exchange: TSX - Region: British Columbia - Primary commodity: Silver - Secondary commodities: Gold, Copper, Lead, Zinc - Document categories: Drill results, Resource update - Extracted: 2026-09-13 19:10:24 UTC Narrative sentiment: 0.10 · Bullish ## Minestarters Atlas summary Coast Copper Corp. is highlighting its Sweeney silver project in northwestern British Columbia, which includes the past-producing Emerald mine. The company presented historical 2012 drill results from the Miya Vein, showing high-grade polymetallic mineralization including silver, gold, copper, lead, and zinc. Additionally, an unclassified historical reserve from the Emerald Vein was noted, though both the drill results and reserve estimate are explicitly stated as not NI 43-101 compliant and not verified by a Qualified Person. Reasoning: The release highlights historical high-grade polymetallic drill results from 2012 and an unclassified historical resource estimate at the Sweeney project. While the grades are strong, the data is old, not NI 43-101 compliant, and not verified by the current QP, limiting its current materiality and confidence. Future exploration plans are positive but lack detail. - Positive factor: High historical grades - Positive factor: Polymetallic mineralization - Positive factor: Future exploration plans - Positive factor: Strategic location near active mining camps - Negative factor: Drill results are historical \(2012\) - Negative factor: Historical data not NI 43-101 compliant - Negative factor: Historical data not verified by current QP - Negative factor: No true width disclosed for drill intercepts - Negative factor: Historical resource estimate is unclassified and non-compliant Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 39 ## Classification and evidence **Stale Data Re-release** Polarity: negative Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty. Why it applies: The document highlights drill results from 2012 and historical reserves, which are not new assays or reinterpretation. Evidence · text > Historical mining of silver \(" Ag "\), copper \(" Cu "\), lead \(" Pb "\) and zinc \(" Zn "\) on the Emerald Vein...subsequent drilling on the crosscutting Miya Vein confirmed similar polymetallic mineralization with the addition of gold \(" Au "\) values up to 7 grams per tonne \(" g/t "\) Au in 2012 drilling. **No QA/QC Disclosure** Polarity: negative Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document. Why it applies: The document explicitly states that historical information cannot be relied upon as the Company's QP has not prepared nor verified it, indicating a lack of verifiable QA/QC for the presented historical data. Evidence · text > Historical information provided cannot be relied upon as the Company's QP as defined under NI 43-101 has not prepared nor verified the historical information. **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 there is insufficient geological information to determine true widths of mineralization for the reported drill intercepts. Evidence · text > \* There is insufficient geological information available to determine true widths of mineralization. **Historical Estimate Only** Polarity: negative Definition: Estimate pre-dates or does not comply with current JORC/NI 43-101 standards — requires verification drilling. Why it applies: The document refers to 'Unclassified historical reserves' and explicitly states that 'The stated resource is not NI 43-101 compliant, and a Qualified Person has not done sufficient work as per NI 43-101 to classify the historical estimate as a current mineral resource'. Evidence · text > Unclassified historical reserves were reported on the Emerald Vein of 40,800 tonnes grading 355 grams per tonne \(" g/t "\) Ag, 8.23% Pb, 9.49 % Zn and 1.13 g/t Au... The stated resource is not NI 43-101 compliant, and a Qualified Person has not done sufficient work as per NI 43-101 to classify the historical estimate as a current mineral resource **No QP/CP Disclosure** Polarity: negative Definition: No Qualified Person or Competent Person named — lower credibility for the estimate. A QP/CP should be a member of a recognized professional association with relevant experience. Why it applies: The historical resource estimate is explicitly stated as not NI 43-101 compliant and not verified by a Qualified Person. Evidence · text > The stated resource is not NI 43-101 compliant, and a Qualified Person has not done sufficient work as per NI 43-101 to classify the historical estimate as a current mineral resource and Coast Copper Corp. is not treating this historical estimate as current mineral resources. **Nearology Play** Polarity: neutral Definition: Value premise rests on proximity to a known deposit rather than own results. Why it applies: The company highlights its project's location relative to other deposits and operations, including the Huckleberry mine and Surge's Berg deposit, to emphasize its potential. Evidence · text > The road accessible Sweeney project \(1,492 hectares\) is centrally located in the Huckleberry mine camp and is 7 km north-northwest of the past producing Huckleberry mine, 3 km west of Huckleberry Mines Ltd.'s Whiting Creek deposit and 8 km southeast of Surge's Berg deposit ## Extracted facts Stored fact records: 39.

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.
