These results confirm the extension of gold mineralization at depth below the current pit design and will be incorporated into an updated block model and pit design to support a revised life-of-mine plan and Mineral Reserve estimate. The company plans to release an updated Mineral Resource and Mineral Reserve estimate in Q1 2027. Reasoning: The infill drilling program at Lindero Mine returned multiple long intercepts with gold grades consistent with or higher than the block model, extending mineralization at depth and supporting an upcoming Mineral Resource and Reserve estimate update. The program also included robust QA/QC. - Positive factor: Long intercepts with good gold grades for a porphyry deposit - Positive factor: Extends gold mineralization significantly below current reserve pit design - Positive factor: Infill drilling confirms continuity and upgrades Inferred Mineral Resources - Positive factor: Supports an upcoming updated Mineral Resource and Reserve estimate - Positive factor: Comprehensive QA/QC procedures disclosed with QP sign-off - Negative factor: True width not defined due to circular nature of mineralization, leading to apparent width only Facts used in scoring: 3 ## Classification and evidence No classification tags are available. ## Extracted facts Stored fact records: 3.

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.
