# Cleghorn Minerals Reports on Recent Channel Sampling Results from Historical Trenches & Pits on The Meech Lake - Matachewan Prospect Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/cleghorn-minerals-reports-on-recent-channel-sampling-results-from-historical-tre--3ba11c92-1cce-4bc2-955a-fea6ecd30422 Original source: https://money.tmx.com/en/quote/CZZ/news/4649796076015826/cleghorn-minerals-reports-on-recent-channel-sampling-results-from-historical-tre Publisher: tmx Original announcement: 2024-11-14T14:18:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Cleghorn Minerals Ltd. - Ticker: CZZ - Exchange: TSX - Region: northeastern Ontario - Primary commodity: Nickel - Secondary commodities: Copper, Platinum, Palladium, Gold, Silver, Zinc - Document categories: Drill results, Other - Extracted: 2026-09-15 19:18:33 UTC Narrative sentiment: 0.40 · Bullish ## Minestarters Atlas summary Cleghorn Minerals has reported surface channel sampling results from historical trenches and pits at the Meech Lake - Matachewan Prospect in Ontario. Highlights include a high-grade Ni-Cu-PGE intercept at Kell's Showing and several Au-Ag-Zn intercepts at the Waterhole and Kell's Cabin showings, confirming two distinct mineralized systems. Reasoning: The release reports high-grade surface channel samples that confirm the presence of two mineralized trends \(Ni-Cu-PGE and Au-Ag-Zn\), though they lack the depth/volume certainty of drill results. - Positive factor: High-grade Ni-Cu-PGE intercepts in Trench 5 - Positive factor: Confirmation of two distinct mineralized systems - Positive factor: QA/QC protocols and QP sign-off disclosed - Negative factor: Results are from surface channel sampling, not drill intercepts Facts used in scoring: 12 ## 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 ALS Minerals as an accredited laboratory and details specific assay methods \(4 Acid/ICP-AES, fire assay\). Evidence · text > All channel samples were submitted to ALS Minerals, an accredited mineral analysis laboratory. **QP/CP Signed** Polarity: positive Story-specific tag Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience. Why it applies: Michael P. Rosatelli, P.Geo. is designated as the Qualified Person. Evidence · text > Michael P. Rosatelli, P.Geo. and senior geological consultant to Cleghorn, is the designated "qualified person" ## Extracted facts Stored fact records: 12.

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.
