The company is also expanding drilling programs at both Berenguela and the Challacollo silver-gold project in Chile. Reasoning: The company is advancing its Berenguela PFS and expanding drilling at both Berenguela and Challacollo, supported by high-grade historical intercepts. - Positive factor: PFS on track and on budget - Positive factor: Expansion of drilling programs at two assets - Positive factor: High-grade silver intercept reported Facts used in scoring: 4 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: 14,252 g/t silver is exceptionally high grade. Evidence · text > 14,252g/t silver **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: Company is performing infill drilling at Berenguela to upgrade resource categories. Evidence · text > including infill drilling ## 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.
