The Berenguela program aims to infill for resource conversion and explore high-grade copper targets, while the Challacollo program seeks to expand the existing resource. Reasoning: The announcement focuses on the commencement of new drilling programs at two projects and references a very recent MRE update for Berenguela. - Positive factor: continuation of drilling at flagship Berenguela - Positive factor: commencement of drilling at Challacollo - Positive factor: recent MRE update at Berenguela Facts used in scoring: 24 ## Classification and evidence **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The document references a new MRE published on December 4, 2025, for Berenguela. Evidence · text > A new MRE was published on December 4, 2025 **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The Challacollo resource is based on a NI 43-101 technical report. Evidence · text > substantial historic NI43-101 silver resource ## Extracted facts Stored fact records: 24.
