These results are crucial for upgrading mineral resources from Inferred to Measured and Indicated categories, supporting a future Pre-Feasibility Study and the declaration of Proven and Probable reserves. The company is actively drilling with six rigs, focusing on infill and geotechnical work, with an updated mineral resource estimate anticipated for Q3-2026. Reasoning: The infill drilling program delivered exceptionally long and high-grade copper equivalent intercepts, which are explicitly aimed at upgrading Inferred resources to Measured and Indicated categories, a critical step for the upcoming Pre-Feasibility Study and the declaration of Proven and Probable reserves, significantly de-risking the Altar project. - Positive factor: long\_intercepts - Positive factor: high\_grade\_intercepts - Positive factor: resource\_conversion\_potential - Positive factor: pfs\_support - Positive factor: true\_width\_disclosed - Positive factor: qaqc\_disclosed - Positive factor: qp\_signed - Positive factor: certified\_lab - Negative factor: deleterious\_elements\_present 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: Hole ALD-26-049EXT reported 936.00 m of 0.66% CuEq, including 194.00 m of 0.99% CuEq, which is an exceptionally long and high-grade intercept for a porphyry copper deposit. Evidence · text > 936 m of 0.66% CuEq \(0.62% Cu, 0.09 g/t Au and 1.16 g/t Ag\), including 194 m of 0.99% CuEq \(0.92% Cu, 0.19 g/t Au and 1.02 g/t Ag\) **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. **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The document mentions that 'Holes with the suffix EXT are extensions of previously drilled holes', indicating step-out drilling. Evidence · text > Holes with the suffix EXT are extensions of previously drilled holes. **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 includes a detailed 'Sampling and Analytical Procedures' section outlining systematic and rigorous QA/QC protocols, including certified standards, blanks, and duplicates. Evidence · text > Altar follows systematic and rigorous sampling and analytical protocols which meet and exceed industry standards. These protocols are summarized below and are available on the Aldebaran website at www.aldebaranresources.com . **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The drilling program is explicitly described as an 'infill drilling program' aimed at upgrading resources. Evidence · text > results of five holes from the infill drilling program at the Altar project **Category Upgrade** Polarity: positive Definition: Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured. De-risking signal. Why it applies: The primary goal of the drilling was to 'upgrade resource blocks classified as Inferred to the Measured & Indicated categories'. Evidence · text > The goal of these holes was to upgrade resource blocks classified as Inferred to the Measured & Indicated categories. **PFS-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Pre-Feasibility Study — requires adequate M&I component. Why it applies: The results will 'provide valuable information as we move toward a resource update and pre-feasibility study' and are 'critical for mineral resource conversion' for a prefeasibility study. Evidence · text > These holes will provide valuable information as we move toward a resource update and pre-feasibility study. **Deleterious Elements Present** Polarity: negative Definition: Penalty elements \(arsenic, antimony, etc.\) or refractory concerns noted in the release. Why it applies: Arsenic \(As\) is reported in the assay table for multiple intercepts, indicating its presence in the mineralization. Evidence · table > As \(ppm\) Context: Interval \(m\) ## Extracted facts Stored fact records: 102.

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.
