The update will include a revised Mineral Resource Estimate for both Colquipucro and Ayawilca, with results expected in early 2027. Reasoning: The announcement of a new PEA update evaluating a staged development strategy \(open-pit silver followed by underground polymetallic\) is a significant project de-risking and value-enhancement signal. - Positive factor: Commencement of PEA update to evaluate staged development - Positive factor: Potential to reduce initial capital requirements via Colquipucro open-pit - Positive factor: Significant increase in silver prices since previous assessment - Positive factor: Planned 5,000m drilling programme to expand resources - Negative factor: Results not expected until early 2027 Facts used in scoring: 6 ## Classification and evidence **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The company has commenced an updated Mineral Resource Estimate for Colquipucro and Ayawilca.

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.
