This update resulted in a 60% increase in contained copper equivalent metal and substantial growth in contained gold, copper, molybdenum, and rhenium. The NI 43-101 compliant estimate, with an effective date of July 31, 2026, will be used for the ongoing pre-feasibility study, which is targeted for completion in Q1 2027. Reasoning: The integrated resource estimate shows significant increases in Indicated tonnage and contained metal for copper, gold, molybdenum, and rhenium, with a high M&I percentage, supporting the ongoing pre-feasibility study. - Positive factor: Tonnage Growth - Positive factor: Contained Metal Growth - Positive factor: Category Upgrade - Positive factor: QP/CP Signed - Positive factor: NI 43-101 Compliant - Positive factor: Cut-off Disclosed - Positive factor: PFS-Supporting Facts used in scoring: 157 ## Classification and evidence **Indicated Resource** Polarity: positive Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves. Why it applies: The document reports a significant Indicated Resource of 1.2 billion tonnes, representing a high level of geological confidence. Evidence · text > The 2026 Resource Estimate contains an Indicated Resource of 1.2 billion tonnes **Category Upgrade** Polarity: positive Definition: Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured. De-risking signal. Why it applies: The company successfully converted Inferred material to Indicated at Northwest Expo, increasing Indicated tonnage by 133%. Evidence · text > At Northwest Expo, we successfully converted Inferred material, increasing Indicated tonnage by 133% **Tonnage Growth** Polarity: positive Definition: Tonnage increase reaching the strong tier vs prior estimate, with grade maintained or improved. Why it applies: Indicated Resources increased by 330 million tonnes, a 36% increase, compared to the prior estimate. Evidence · text > Increased Indicated Resources by 330 million tonnes \(+36%\) **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 equivalent metal in Indicated Resources increased by 60%, with contained gold up 81%, copper up 84%, molybdenum up 46%, and rhenium up 43%. Evidence · text > 60% increase in contained Cu Eq. metal in Indicated Resources **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: Sue Bird, P.Eng., and Peter Mehrfert, P.Eng., both Qualified Persons as defined by NI 43-101, reviewed and approved the technical disclosure. Evidence · text > Sue Bird, P. Eng, V.P. of MMTS, and a Qualified Person as defined by NI 43-101, has reviewed and approved the scientific and technical disclosure... Peter Mehrfert, P.Eng., \(Ausenco\) reviewed and verified... Mr. Mehrfert is a Qualified Person under NI 43-101. **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 was prepared in accordance with National Instrument 43-101. Evidence · text > A technical report \(the “Technical Report”\) prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects \(“NI 43-101”\) **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 resource estimate clearly states an $11.00/tonne NSR cut-off. Evidence · text > at an $11.00/tonne NSR cut-off **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: The estimate includes a significant Inferred Resource of 260 million tonnes, which is a speculative category. Evidence · text > plus an Inferred Resource of 260 million tonnes **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The document announces an integrated mineral resource estimate for the North Island Project, updating previous estimates. Evidence · text > Northisle Announces Significant Increase to North Island Resource Estimate **PFS-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Pre-Feasibility Study — requires adequate M&I component. Why it applies: The 2026 Resource Estimate will be used for the development of a pre-feasibility study \(PFS\) on the North Island Project. Evidence · text > The 2026 Resource Estimate will be used for the development of a pre-feasibility study \(“PFS”\) on the North Island Project ## Extracted facts Stored fact records: 157.

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.
