Highlights include 936 meters at 0.66% CuEq, with a higher-grade section of 194 meters at 0.99% CuEq. These results demonstrate consistent mineralization and are crucial for the upcoming resource update and pre-feasibility study, with all intervals representing true thickness. Reasoning: The infill drilling program at the Altar project delivered very long intercepts with strong to exceptional copper equivalent grades, confirming mineralization consistency and supporting the upgrade of resources for a pre-feasibility study. The transparent reporting enhances confidence in the results, despite the presence of arsenic. - Positive factor: Exceptional and strong copper equivalent grades over significant widths for a porphyry deposit - Positive factor: Infill drilling successfully targets resource conversion from Inferred to Measured & Indicated categories, de-risking the project - Positive factor: Transparent disclosure of metal equivalent assumptions, QA/QC procedures, and true width of intercepts - Positive factor: Results support an upcoming resource update and pre-feasibility study - Negative factor: Presence of arsenic, a deleterious element, is noted in some intercepts Facts used in scoring: 102 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: The intercept of 194 m at 0.99% CuEq is an exceptionally high-grade zone for a porphyry copper deposit, exceeding the exceptional threshold of 0.8% CuEq. Evidence · table > 0.99 Context: 194.00 **True Width Disclosed** Polarity: positive Definition: Actual thickness perpendicular to structure is stated, not just downhole length. Why it applies: The document explicitly states that 'Intervals represent the true thickness of the deposit.' Evidence · text > Intervals represent the true thickness of the deposit. **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 release details systematic sampling protocols, use of certified control standards, blanks, and duplicates, and mentions ALS as the certified laboratory. Evidence · text > Altar follows systematic and rigorous sampling and analytical protocols which meet and exceed industry standards. ... Aldebaran independently inserts certified control standards \(Super Certified Reference Materials \(SCRM’s\), coarse field blanks, and duplicates into the sample stream to monitor data quality. **Compositing Transparent** Polarity: positive Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals. Why it applies: The document states 'The grades are uncut' and provides clear from/to depths and interval lengths, implying transparent compositing. Evidence · text > The grades are uncut. **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The drilling program is explicitly described as 'infill drilling program' with the goal to 'upgrade resource blocks classified as Inferred to the Measured & Indicated categories'. Evidence · text > infill drilling program at the Altar project in San Juan, Argentina. The goal of these holes was to upgrade resource blocks classified as Inferred to the Measured & Indicated categories. **Deleterious Elements Present** Polarity: negative Definition: A source-stated penalty, refractory or recovery concern in the fact's scope. Element detection alone, including measured elements explicitly below penalty thresholds, does not trigger this tag. Respect negation and retain a separately stated concern even when another risk is explicitly absent. Why it applies: Arsenic \(As\) is reported in the assay table for multiple intercepts, which is a known deleterious element in copper concentrates.

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.
