The 2025-2026 infill and geotechnical drilling program aims to upgrade Inferred resources to higher-confidence categories and will incorporate over 40,000 meters of drilling at Altar and 30,000 meters at the new Radio Porphyry target into an upcoming 2026 mineral resource estimate. These results are expected to support a Pre-Feasibility Study scheduled for 2027. Reasoning: The drill results demonstrate exceptional intercept lengths and significant higher-grade zones within a large porphyry system, with clear intent to upgrade resources and incorporate new targets. The transparency in reporting and QA/QC further supports a strong positive interpretation, despite the presence of arsenic. - Positive factor: Exceptional intercept lengths, including 1,728.9 meters in ALD-26-260, indicating a large mineralized system. - Positive factor: High-grade included intervals, such as 756 meters at 0.68% CuEq in ALD-26-260 and 196 meters at 0.73% CuEq in ALD-26-265, exceeding the 75th percentile for porphyry copper deposits. - Positive factor: Explicit disclosure that intervals represent true thickness, enhancing confidence in the reported widths. - Positive factor: The drilling program is designed to upgrade Inferred resources to Measured and Indicated categories, de-risking the project. - Positive factor: Upcoming inclusion of the Radio Porphyry target in the mineral resource estimate, representing a new area of potential growth. - Positive factor: Comprehensive QA/QC protocols, certified lab usage, and QP sign-off ensure data reliability. - Positive factor: Metal equivalent assumptions are fully disclosed, providing transparency for calculations. - Negative factor: Presence of arsenic as a deleterious element, which could pose processing or concentrate quality challenges. - Negative factor: Some intervals, particularly the broader ones, show grades below the project average for copper, though still significant due to length.

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.
