Key intercepts include 44.7 meters at 3.0% copper equivalent at Minto North, confirming grade continuity and extending mineralization. These results are crucial for an upcoming resource update in Q1 2027, which will support the project's feasibility study. Reasoning: Selkirk Copper reported strong Phase 2 drill results from its Minto project, including high-grade copper equivalent intercepts over significant widths, which exceeded the planned meterage and will feed into a 2027 resource update supporting a feasibility study. - Positive factor: High-grade copper equivalent intercepts - Positive factor: Significant intercept widths - Positive factor: Drilling exceeded planned meterage - Positive factor: Confirmation of grade continuity - Positive factor: Extension of known mineralization - Positive factor: Results feeding into upcoming resource update for feasibility study - Negative factor: Internal waste noted in a key intercept - Negative factor: True widths are estimated as a range, not precisely stated - Negative factor: No QA/QC disclosure in the release - Negative factor: Cut-off grades for compositing are not disclosed Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 22 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: The 44.7-meter intercept at Minto North grading 3.0% copper equivalent, including higher-grade sub-intervals up to 6.45% CuEq, is described as one of the best grade-by-width results of the entire drill program. Evidence · text > 44.7 meters grading 2.12% copper, 1.16 grams per tonne gold and 10.7 grams per tonne silver, or 3.0% copper equivalent. ... The company ranks the 44.7-meter result among the best grade-by-width intercepts across Phase 1 and Phase 2 combined. **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Step-out drilling at Area 118 extended the 301, 120, and 160 lenses, and a new 302 Lens was identified at Copper Keel, open to the east and south. Evidence · text > Area 118 Step-Outs Extended Lenses Close to Existing Underground Development ... 2 other holes tested the newly identified 302 Lens, where mineralization is open to the east and south at 50 to 70 meters below surface. **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: Infill drilling at Minto North's 202 Lens, Copper Keel's 101 Lens, and Minto Main's 114/117 lenses confirmed grade continuity and modeled geometry. Evidence · text > Infill drilling at the 202 Lens returned 44.7 meters grading... Copper Keel Infill Confirmed the Modeled Geometry... Infill drilling across the 114 and 117 lenses at Minto Main returned 27 meters grading... **Apparent Width Only** Polarity: negative Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: Intercepts are reported as drill-core lengths, with true widths estimated as 80% to 90% of these lengths, indicating that precise true widths are not provided. Evidence · text > Reported intercepts represent drill-core lengths; the company estimates true widths at approximately 80% to 90% of the core lengths. **No QA/QC Disclosure** Polarity: negative Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document. Why it applies: The release does not disclose any information regarding QA/QC procedures, laboratory certifications, or Competent/Qualified Person sign-off. Evidence · text > Selkirk Copper's Phase 2 Drilling Feeds Into Minto's 2027 Resource Update: 7 Things You Need to Know **Cut-off Undisclosed** Polarity: negative Definition: High-grade interval reported without stating the cut-off grade used for compositing. Why it applies: High-grade intervals are reported without stating the cut-off grade used for compositing. Evidence · text > Selkirk Copper's Phase 2 Drilling Feeds Into Minto's 2027 Resource Update: 7 Things You Need to Know **Compositing Transparent** Polarity: positive Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals. Why it applies: The main 44.7-meter intercept at Minto North explicitly states it includes an internal waste interval grading less than 0.1% copper equivalent. Evidence · text > Selkirk reported the Minto North result as a single 44.7-meter interval, which includes an internal waste interval grading less than 0.1% copper equivalent. ## Extracted facts Stored fact records: 22.

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.
