The drilling is supporting the upgrade of mineral resources to the Measured category and aims to define Proven Mineral Reserves within the starter pit. Reasoning: The announcement reports successful infill drilling results that are supporting the upgrade of resources to the Measured category and the future declaration of Proven Reserves, which is a key de-risking milestone for the Feasibility Study. - Positive factor: high Mineral Resource conversion rate - Positive factor: definition of Measured zone - Positive factor: consistent grades with expectations - Positive factor: QA/QC disclosed - Negative factor: only 62% of assays received to date Facts used in scoring: 5 ## 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 drilling program to define Measured resources and Proven reserves. Evidence · text > planned Feasibility Study infill 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 release details the use of blanks, standards, and duplicates and names the laboratory. Evidence · text > implemented a full QA/QC program using blanks, standards, and duplicates **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The drilling is focused on infill and definition within the starter pit rather than new discovery. Evidence · text > tighter space drilling, providing a basis for the targeted declaration of Proven Mineral Reserves ## Extracted facts Stored fact records: 5.

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.
