The report is dated January 13, 2025 and has an effective date of December 3, 2024, with no material differences from the results disclosed on that date. The release also restates the project's current Proven and Probable Mineral Reserve estimate of 42.3 Mt grading 91 g/t Ag and 0.81 g/t Au, containing approximately 124 Moz silver and 1.1 Moz gold. Reasoning: This is primarily a PFS filing announcement, with a reserve summary and a mention of an earn-in JV elsewhere in the body. The news is positive for project de-risking, but the release itself is mostly administrative and does not disclose the full economic model. - Positive factor: Updated NI 43-101 compliant pre-feasibility study filed for Diablillos. - Positive factor: The report has an effective date of December 3, 2024 and is described as having no material differences from the December 3, 2024 results disclosure. - Positive factor: The project's current Proven and Probable Mineral Reserve estimate is stated in the release. - Negative factor: No detailed study metrics such as NPV, IRR, capex, opex, or payback are provided in this release. - Negative factor: No new resource or reserve figures are announced beyond the summary reserve statement. - Negative factor: The release says there are no material differences from the prior disclosure, limiting incremental novelty. - Rubric flag: resource\_update completeness — If the full PFS contains an estimate table or economic metrics, extract those separately only when they are explicitly present in the provided document text. Facts used in scoring: 2 ## Classification and evidence **PFS-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Pre-Feasibility Study — requires adequate M&I component. Why it applies: The title and body state that a 'updated pre-feasibility study' has been filed. Evidence · text > filed on SEDAR+ a National Instrument 43-101 – Standards of Disclosure for Mineral Projects compliant updated pre-feasibility study **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The report is stated to be 'National Instrument 43-101 ... compliant'. Evidence · text > National Instrument 43-101 – Standards of Disclosure for Mineral Projects compliant updated pre-feasibility study **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The release restates the current Proven and Probable Mineral Reserve estimate for Diablillos.

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.
