The company also announced the appointment of Richard Leclerc as General Manager and provided updated Mineral Resource figures from its recent PEA. Reasoning: The announcement of a major 40,000m infill program to upgrade resources for a feasibility study is a significant de-risking milestone for a copper-gold project. - Positive factor: Commencement of large 40,000m infill drilling program - Positive factor: Significant existing resource base \(357 Mt total\) - Positive factor: Clear path to feasibility study - Positive factor: Appointment of experienced General Manager - Negative factor: High proportion of Inferred resources \(72%\) Facts used in scoring: 4 ## Classification and evidence **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The 40,000m program is explicitly described as infill drilling to support resource conversion. Evidence · text > 40,000-metre infill drilling program underway **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: A large portion of the reported resource \(256.3 Mt\) is in the Inferred category. Evidence · text > Inferred Mineral Resources - 256.3 Mt at 0.34% copper **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 specific QA/QC methods including standards, blanks, and duplicates. Evidence · text > The Company employed a rigorous QAQC program involving certified standards, blank, ¼ core duplicates and coarse reject duplicates. ## Extracted facts Stored fact records: 4.

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.
