The latest assays confirm continuity of mineralization over 1.1km, extend known mineralization by up to 50m down dip, and identify high-grade zones on previously undrilled sections. The company believes the project has substantial depth potential and is located near major gold deposits. Reasoning: The announcement reports high-grade gold intercepts from 18 RC holes at Golden Boulder, extending known mineralization by up to 50m down dip and identifying high-grade zones on previously undrilled sections. These results demonstrate significant depth potential and continuity over 1.1km, comparing favorably to prior project averages. Detailed QA/QC procedures are disclosed, but true widths are not confirmed. - Positive factor: High-grade intercepts - Positive factor: Continuity of mineralization - Positive factor: Step-out extension - Positive factor: Mineralization from surface - Positive factor: Depth potential - Positive factor: Proximity to major deposits - Positive factor: Detailed QA/QC disclosed - Negative factor: Apparent width only - Negative factor: No true width reported Facts used in scoring: 101 ## Classification and evidence No classification tags are available. ## Extracted facts Stored fact records: 101.

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.
