The Berenguela Pre-Feasibility Study remains on track for early 2027, while the Challacollo project continues with an extended diamond drilling program. Reasoning: The company is advancing its Berenguela PFS and continuing exploration at Challacollo, though the resource data provided for Challacollo is a restatement of a 2020 estimate. - Positive factor: PFS on schedule - Positive factor: ongoing drilling at two projects - Positive factor: resource update provided for Challacollo - Negative factor: Challacollo resource is historical \(2020\) Facts used in scoring: 19 ## Classification and evidence **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: Challacollo project contains a significant portion of Inferred resources. Evidence · text > Inferred \| Open Pit \| 2,360 \| 117 \| 0.15 **Indicated Resource** Polarity: positive Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves. Why it applies: Challacollo project has Indicated resources reported. Evidence · text > Indicated \| Open Pit \| 5,597 \| 170 \| 0.27 **QP/CP Signed** Polarity: positive Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

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.
