The results feature significant continuous copper-equivalent mineralization, including an interval exceeding 1.7 km in hole ALD-26-260, supporting an upcoming mineral resource update. Reasoning: Strong continuous copper-equivalent intercepts from an infill program designed to upgrade resource confidence. - Positive factor: Long continuous mineralized intervals \(up to 1.7 km\) - Positive factor: Infill drilling supporting resource upgrade to Measured/Indicated - Positive factor: Expansion towards Radio Porphyry target - Negative factor: Some holes drilled for geotechnical purposes only Facts used in scoring: 16 ## Classification and evidence **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The program is described as an infill and geotechnical drilling program to upgrade resource confidence. Evidence · text > results from all remaining holes of the 2025-2026 infill and geotechnical drilling program **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 document mentions refining geological and geotechnical models based on recent drilling, though specific lab names/methods are not in this snippet, the context of a formal program is implied. Evidence · text > refining and improving our geological and geotechnical models based on this recent drilling ## Extracted facts Stored fact records: 16.

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.
