These studies aim to support environmental permitting and underground mine engineering, following a strong Preliminary Economic Assessment. Reasoning: The company is advancing the New Amalga project through critical environmental and engineering studies \(geochemical and backfill testing\) required for permitting and mine design. - Positive factor: Initiation of formal geochemical characterization to advance permitting - Positive factor: Backfill testwork to support underground mining design - Positive factor: High-grade historical intercepts mentioned - Positive factor: Strong PEA economics \(NPV $721m at $3,200 gold\) - Negative factor: Geochemical testing is a standard requirement, not a discovery Facts used in scoring: 19 ## Classification and evidence **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: The release mentions previous geochemical testing and current program oversight by SGS North America and Stantec. Evidence · text > Labwork will be performed by SGS North America with program design and technical oversight provided by Stantec Consulting Services Inc. **Bonanza Intercept** Polarity: positive Story-specific tag Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Multiple intercepts exceed high-grade thresholds for gold. Evidence · text > 3.1 m grading 79.2 g/t Au **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The resource estimate and technical disclosure are reviewed and approved by a QP under NI 43-101. Evidence · text > Kyle Mehalek, P.E.., is the QP within the meaning of NI 43-101 ## Extracted facts Stored fact records: 16.

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.
