At New Afton, drilling at the K-Zone extended mineralization by over 300 meters, with notable copper-gold intercepts. At Rainy River, expansion and infill drilling demonstrated strong gold-silver mineralization, extending underground zones and supporting potential resource upgrades and open-pit connectivity. Reasoning: Coeur Mining's exploration update reports strong drill results from both New Afton and Rainy River, demonstrating significant extensions of mineralization and potential for resource growth and mine life extension, supported by true width disclosures and QP review. The results include high-grade intercepts and indicate potential for resource upgrades. - Positive factor: Significant step-out extensions of mineralization at both projects - Positive factor: High-grade gold intercepts, particularly at Rainy River - Positive factor: True widths disclosed for all reported intercepts - Positive factor: Potential for resource classification upgrades from infill drilling - Positive factor: Qualified Person sign-off on technical information Facts used in scoring: 53 ## Classification and evidence **True Width Disclosed** Polarity: positive Definition: Actual thickness perpendicular to structure is stated, not just downhole length. Why it applies: The document explicitly states 'All drill intervals are estimated true widths.' for the reported intercepts. Evidence · text > All drill intervals are estimated true widths. **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: The news release states that the scientific and technical information has been reviewed and approved by a 'qualified person' under Item 1300 of Regulation S-K. Evidence · text > The scientific and technical information concerning our mineral projects in this news release has been reviewed and approved by a “qualified person” under Item 1300 of Regulation S-K **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The expansion drilling program at K-Zone has extended mineralization by more than 300 meters beyond the original footprint. Evidence · text > The expansion drilling portion of this year’s program has extended mineralization by more than 300 meters beyond the original footprint **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The 2026 program includes infill drilling at K-Zone and ODM Main Zone to confirm existing mineralization and support resource conversion. Evidence · text > The infill drilling portion of the 2026 program has confirmed existing mineralization **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: The intercept RR26-2110-W1A returned 43.6 g/t gold over 5.8 meters, which is exceptionally high-grade for an orogenic underground deposit. Evidence · text > 5.8 meters at 43.6 g/t gold **Category Upgrade** Polarity: positive Definition: Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured. De-risking signal. Why it applies: Infill drilling results at Rainy River are expected to support the potential upgrade of mineral resource classification from inferred to measured and indicated. Evidence · text > The positive results are expected to support the potential upgrade of mineral resource classification from inferred to measured and indicated at year-end. ## Extracted facts Stored fact records: 53.

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.
