The infill and geotechnical drilling program, aimed at upgrading resources and supporting a future Pre-Feasibility Study, confirmed long continuous intervals of copper mineralization. The company plans to incorporate over 70,000 meters of new drilling into an updated mineral resource estimate, which will include the Radio Porphyry target for the first time. Reasoning: The drilling program at Altar delivered exceptionally long copper-gold-silver-molybdenum intercepts, with several intervals exceeding the 75th percentile for porphyry copper grades, confirming significant and continuous mineralization for the upcoming resource update and pre-feasibility study. The disclosure of true widths and robust QA/QC procedures further enhances confidence in these results. - Positive factor: Exceptionally long intercepts, including one over 1.7 km, confirming significant and continuous mineralization. - Positive factor: Several high-grade sub-intervals exceeding the 75th percentile for porphyry copper deposits. - Positive factor: Infill drilling program designed to upgrade Inferred resources to higher-confidence Measured and Indicated categories, de-risking the project. - Positive factor: True width of intervals is explicitly stated, providing high confidence in reported thicknesses. - Positive factor: Comprehensive QA/QC procedures are disclosed, including certified lab and QP sign-off. - Positive factor: Upcoming resource update will incorporate significant new drilling and include the Radio Porphyry target for the first time, positioning the project for a Pre-Feasibility Study. - Negative factor: Arsenic is reported as a deleterious element in several intercepts, which could pose processing or concentrate quality challenges.

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.
