The Measured & Indicated resource now stands at 50.4Mt at 2.0% CuEq, representing a 113% increase in contained copper for that category. Reasoning: The announcement reports a major expansion of the Green Bay Mineral Resource, with tonnage increasing by 51% and contained copper more than doubling in the M&I category compared to the October 2024 estimate. - Positive factor: Significant tonnage growth \(51%\) - Positive factor: Substantial contained copper increase \(+113% M&I\) - Positive factor: High grade copper equivalent \(2.0% CuEq M&I\) - Positive factor: Project advancing towards PEA completion Facts used in scoring: 3 ## Classification and evidence **Tonnage Growth** Polarity: positive Definition: Tonnage increase reaching the strong tier vs prior estimate, with grade maintained or improved. Why it applies: Total Mineral Resource increased by 51% compared to the previous MRE. Evidence · text > This was a 51% increase from the previous Mineral Resource Estimate \(MRE\) of October 2024 **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: Contained copper in the M&I category increased by 113%. Evidence · text > Contained copper increased to 863kt M&I \(+113%\) **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The document reports a revised Mineral Resource Estimate. Evidence · text > Total Green Bay Mineral Resource increased to 50.4Mt @ 2.0% Copper Equivalent \(CuEq\) **PEA-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study. Why it applies: The resource update is part of a Preliminary Economic Assessment \(PEA\) currently underway. Evidence · text > Preliminary Economic Assessment on Green Bay Copper-Gold Project on track for completion ## Extracted facts Stored fact records: 3.

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.
