The MRE defines a total Indicated Mineral Resource of 10.04 million tonnes at 1.0% CuEq and a total Inferred Mineral Resource of 18.15 million tonnes at 1.7% CuEq, demonstrating substantial resources at shallow depths. The estimate, prepared by independent Qualified Persons, highlights the project's potential for expansion and supports its advancement towards a Preliminary Economic Assessment. Reasoning: T2 Metals announced a maiden NI 43-101 compliant Mineral Resource Estimate for its Sherridon Project, defining significant Indicated and Inferred resources of copper, zinc, gold, and silver across four VMS deposits, with clear potential for expansion and strong infrastructure, supporting advancement to a PEA. - Positive factor: Maiden NI 43-101 compliant MRE for the project - Positive factor: Substantial Indicated and Inferred resources defined - Positive factor: High-grade near-surface mineralization identified - Positive factor: Deposits remain open for expansion along strike and at depth - Positive factor: Multiple Qualified Persons signed off on the estimate - Positive factor: Good infrastructure with year-round road and rail access - Positive factor: Co-funding received from Manitoba Mineral Development Fund - Positive factor: MRE supports advancement to a Preliminary Economic Assessment - Negative factor: No Measured resource category defined Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 68 ## 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 explicitly stated as an 'independent NI 43-101 Mineral Resource Estimate'. Evidence · text > independent NI 43-101 Mineral Resource Estimate **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 MRE was prepared by and reviewed by multiple independent Qualified Persons \(QPs\) as defined by NI 43-101. Evidence · text > The MRE was prepared by Geoffrey Reed, MAIG, MAusIMM \(QP\) Geo, of ReedLeyton Consulting Pty Ltd, independent Qualified Person, NI 43-101. **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 is the first formal Mineral Resource Estimate for the Sherridon Project. Evidence · text > This NI 43-101 resource at Sherridon confirms what we have long believed, that this is a robust VMS system with scale, grade, and clear growth potential. **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: The MRE includes a substantial Inferred Mineral Resource of 18.15 million tonnes. Evidence · text > Total Inferred Mineral Resource of 18.15 million tonnes grading 1.08% Cu, 1.00% Zn, 0.27 g/t Au and 7.05 g/t Ag **Indicated Resource** Polarity: positive Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves. Why it applies: The MRE includes a Total Indicated Mineral Resource of 10.04 million tonnes. Evidence · text > Total Indicated Mineral Resource of 10.04 million tonnes \(Mt\) grading 0.39% Cu, 0.83% Zn, 0.30 g/t Au and 4.75 g/t Ag **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 and underground mining methods 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. **PEA-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study. Why it applies: The scale and grade of the MRE are stated to support advancement to a Preliminary Economic Assessment \(PEA\). Evidence · text > Scale and grade of the MRE supports advancement of Sherridon to a Preliminary Economic Assessment \(PEA\) **Tonnage Growth** Polarity: positive Definition: Significant tonnage increase \(≥15%\) vs prior estimate with grade maintained or improved. Why it applies: The maiden MRE defines substantial Indicated and Inferred tonnages for the project. Evidence · text > 10.04 Million Tonnes @ 1.0% CuEq 1 Indicated Plus 18.15 Million Tonnes @ 1.7% CuEq1Inferred **Contained Metal Growth** Polarity: positive Definition: True scale improvement — contained metal ounces/tonnes increased vs prior, accounting for both tonnage and grade changes. Why it applies: The MRE reports significant contained metal for copper, zinc, and gold in both Indicated and Inferred categories. Evidence · text > Project contains 86 million lb of copper and 96,000 oz of gold in the Indicated category and 430 million lb of copper and 158,000 oz gold in the Inferred category ## Extracted facts Stored fact records: 68.

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.
