# T2 Metals Files NI 43-101 Mineral Resource Estimate Report for the Sherridon Copper-Zinc-Gold-Silver Project, Manitoba, Canada Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/t2-metals-files-ni-43-101-mineral-resource-estimate-report-for-the-sherridon-cop--669384ba-b9e2-45f7-8d6a-b6a47f27b4c0 Original source: https://money.tmx.com/en/quote/TWO/news/8611002055032240/t2-metals-files-ni-43-101-mineral-resource-estimate-report-for-the-sherridon-cop Publisher: tmx Original announcement: 2026-06-26T10:30:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: T2 Metals Corp. - Ticker: TWO - Exchange: TSX - Region: Manitoba, Canada - Primary commodity: Copper - Secondary commodities: Zinc, Gold, Silver - Document categories: Resource update - Extracted: 2026-08-20 21:30:53 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary T2 Metals Corp. has filed an NI 43-101 compliant Mineral Resource Estimate for its Sherridon Copper-Zinc-Gold-Silver Project in Manitoba, Canada, defining significant Indicated and Inferred resources across four VMS deposits. The estimate includes 10.04 million tonnes Indicated and 18.15 million tonnes Inferred, with a substantial portion accessible via open pit and supported by existing infrastructure. While the report highlights strong resource potential, a notable discrepancy in the reported contained zinc for one Indicated resource requires further clarification. Reasoning: The company has filed a maiden NI 43-101 compliant Mineral Resource Estimate for its Sherridon project, defining significant copper, zinc, gold, and silver resources across four VMS deposits, with a substantial portion accessible via open pit and good infrastructure. However, a notable discrepancy in contained zinc for one Indicated resource requires clarification. - Positive factor: Significant contained metal in both Indicated and Inferred categories - Positive factor: NI 43-101 compliant report with QP sign-off - Positive factor: Maiden resource estimate for four VMS deposits - Positive factor: Deposits open at depth and along strike - Positive factor: Good existing infrastructure profile - Positive factor: High-grade near-surface mineralization identified - Negative factor: Significant portion of the resource is in the Inferred category - Negative factor: Discrepancy in reported contained zinc for Cold Lake UG Indicated resource - Rubric flag: Contained metal calculation discrepancy — The reported contained zinc for the Cold Lake UG Indicated resource \(40.00 M lb\) is approximately 10 times higher than the calculated contained metal based on the reported tonnes \(0.31 Mt\) and grade \(0.58% Zn\), which should be ~3.96 M lb. This suggests a significant error in the table. Facts used in scoring: 85 ## Classification and evidence **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The resource estimate is prepared in compliance with National Instrument 43-101. Evidence · text > National Instrument 43-101 \("NI 43-101"\) Technical Report **QP/CP Signed** Polarity: positive 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: The Technical Report was authored by independent Qualified Persons as defined under NI 43-101, and the company's President & CEO, a Qualified Person, has reviewed and approved the contents. Evidence · text > Mr. Geoffrey Reed of ReedLeyton Consulting, Mr. Bengt Anders Hogrelius of Hogrelius Geological Consultants, and Mr. Bouke van 't Riet of Arundon Mining Solutions Oy, each an independent Qualified Person as defined under NI 43-101. Each QP has read and approved the scientific and technical information in this news release relating to the Technical Report and the MRE. **Cut-off Disclosed** Polarity: positive Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison. Why it applies: The cut-off grades for both open pit \(US$20/t\) and underground \(US$55/t\) resources are clearly stated. Evidence · text > Mineral resources are estimated at a NSR cut-off of US$20 per tonne and US$55 per tonne for open pit and underground respectively. **Maiden Resource** Polarity: neutral Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. Why it applies: This report defines the initial Mineral Resource Estimate for the four VMS deposits at the Sherridon project. Evidence · text > The MRE encompasses four copper-dominant volcanogenic massive sulphide \("VMS"\) deposits ## Extracted facts Stored fact records: 85.

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.
