The company also reviews historical drill results at the Amalia gold-silver project in Mexico and existing inferred resources at the Holly project in Guatemala. Reasoning: The release highlights positive permitting progress in Peru and provides a summary of existing resource/historical data across the portfolio, though it notes a work suspension at one JV project. - Positive factor: Permitting milestone achieved at Tierra Roja \(technical review for access approved\) - Positive factor: Existing resource at Holly project provides established baseline - Positive factor: Historical high-grade drill results at Amalia project - Negative factor: Amalia project work suspended by JV partner Pan American Silver Facts used in scoring: 5 ## Classification and evidence **Permitting Milestone** Polarity: positive Story-specific tag Definition: No canonical definition is currently available. Why it applies: Technical review for access at Tierra Roja approved by Regional Government of Arequipa Evidence · text > The technical review for access has been approved by the Regional Government of Arequipa \(GREM\) **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: Holly project Peña vein hosts inferred resources Evidence · text > Holly’s Peña vein hosts inferred resources of 1.32Mt at 6.46 g/t Au and 256 g/t Ag **QA/QC Disclosed** Polarity: positive Story-specific tag Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: Qualified Person Bruce Smith is named and has approved the technical information Evidence · text > Qualified Person Bruce Smith, M.Sc. \(Geology\)... has prepared and approved the technical information contained in this news release. ## 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.
